Background

At present, the reticle center of the sighting telescope is arranged on the reticle, and the reticle is arranged inside the lens barrel, so that the gun calibration is realized by adjusting an inner adjusting mechanism of the sighting telescope, namely a distance compensation knob positioned right above the lens barrel and a wind deflection compensation knob positioned at the side edge of the lens barrel, wherein the distance compensation knob can enable the lens barrel to reciprocate along the vertical direction, and the wind deflection compensation knob can enable the lens barrel to reciprocate along the horizontal direction. According to the practical application condition, the distance compensation knob or the windage compensation knob is adjusted to enable the division center to move along the up-down left-right direction, so that the division center is adjusted to a position overlapped with the impact point. However, the gun calibration by the internal adjusting mechanism has the following defects: 1. because the distance between the lens body of the sighting telescope and the lens barrel arranged in the lens body is smaller, the adjustable stroke of the internal adjusting mechanism is smaller, the requirement of large-deviation adjustment cannot be met, and the shooting accuracy cannot be ensured; 2. if the inner diameter of the lens body is increased to enlarge the distance between the lens body and the lens barrel, the size of the sighting telescope is large, the weight of the sighting telescope is increased, the stability of the lens barrel is not facilitated due to the large distance between the lens body and the lens barrel, and the lens barrel is easy to shake, so that the shooting accuracy is affected; 3. since the internal adjustment mechanism adjusts the position of the lens barrel inside the sighting telescope, and the lens barrel is often provided with optical devices, moving the relative position of the lens barrel risks changing the corrected optical path inside the sighting telescope, thereby reducing the sighting accuracy of the sighting telescope.

As used herein, "upper", "lower", "left", "right", "front", "rear", "top", "bottom", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object being described is changed.

As shown in fig. 1 and 2, at least one embodiment of the present invention provides an optical adjustment connection structure for connecting a bracket body 1 and a bracket seat 2, and enabling adjustment in a single direction (up-down direction), which includes a first connection post 31 and a hand wheel device 32, wherein the first connection post 31 is used for connecting the bracket seat 2, the hand wheel device 32 is provided with a receiving hole 33 and a first connection portion 34 for connecting the bracket body 1, the receiving hole 33 is movably sleeved on the first connection post 31, the first connection portion 34 is disposed on an outer surface of the hand wheel device 32, and the hand wheel device 32 can reciprocate along a length direction of the first connection post 31. Specifically, the hand wheel device 32 is connected to the first connecting post 31 through the accommodating hole 33, and meanwhile, the accommodating hole 33 can also guide the hand wheel device 32 to reciprocate along the length direction of the first connecting post 31, when the first connecting post 31 is vertically or obliquely placed relative to a horizontal plane, the direction of reciprocation of the hand wheel device 32 is the up-down direction, so that the hand wheel device 32 drives the first connecting portion 34 and the bracket body 1 connected to the first connecting portion 34 to move up-down together in the up-down movement process. The sighting telescope is arranged on the bracket body 1 or connected to the first connecting part 34, so that the sighting telescope can be adjusted in the up-down direction, namely, the distance compensation adjustment in the gun correction or zeroing setting process is realized, the stroke of the distance compensation adjustment is not limited by the structure of the sighting telescope, and the travel of the containing hole 33 along the length of the first connecting column 31 can be changed, so that the sighting telescope is simple in structure and convenient to operate.

Note that, in this embodiment, the specific manner in which the accommodating hole 33 is movably sleeved on the first connecting post 31 is not limited, as long as the handwheel device 32 can reciprocate along the length direction of the first connecting post 31 through the accommodating hole 33. For example, in order to make the displacement of the handwheel device 32 smoother and more precise and controllable when it reciprocates along the length direction of the first connecting column 31, as shown in fig. 1 and 2, the first connecting column 31 is provided with external threads, the receiving hole 33 includes an internal threaded hole 331, the receiving hole 33 is engaged with the first connecting column 31 through internal and external threads, and the handwheel device 32 can reciprocate along the length direction of the first connecting column 31 through the engagement of the internal and external threads. Specifically, since the receiving hole 33 is connected to the first connecting post 31 by a threaded connection, the hand wheel device 32 can move along the length direction of the first connecting post 31 when rotated clockwise or counterclockwise. In addition, the direction of movement of the handwheel device 32 may be set by thread rotation, and the distance moved by the handwheel device 32 per rotation may also be varied by varying the pitch of the threads. Thus, the above-described manner of coupling the handwheel device 32 to the first coupling post 31 allows for a directional and quantitative movement of the handwheel device 32, thereby providing for smoother, more precise and controlled displacement of the handwheel device 32 during reciprocation. For another example, in other embodiments not shown in the drawings, the outer periphery of the first connecting post 31 is a polished rod, and the inner wall of the receiving hole 33 is provided with an elastic protrusion facing the first connecting post 31, and the elastic protrusion abuts against the outer periphery of the first connecting post 31. Under the elastic force action of the elastic protruding part, a larger friction force exists between the accommodating hole 33 and the first connecting column 31, so that the hand wheel device 32 is relatively fixed with the first connecting column 31 when the hand wheel device 32 is not acted by external force, the hand wheel device 32 is pushed to overcome the friction force, and the hand wheel device 32 can reciprocate along the length direction of the first connecting column 31 and move more stably.

The connection mode of the first connection portion 34 and the bracket body 1 is not limited in this embodiment, as long as the connection mode of the first connection portion 34 and the bracket body 1 does not interfere with the motion of the handwheel device 32, and the first connection portion 34 can drive the bracket body 1 to move along with the handwheel device 32. For example, as shown in fig. 1, the first connecting portion 34 includes at least two outer flanges 341 that are disposed on the outer side wall of the handwheel device 32, where the two outer flanges 341 are disposed between the upper and lower layers, and a space is formed between the two outer flanges 341 for clamping the bracket body 1, so that the bracket body 1 moves reciprocally along the length direction of the first connecting post 31 along with the handwheel device 32 under the driving of the two outer flanges 341.

The setting of initial zeroing is required to be performed according to a certain shooting distance before the sighting telescope leaves the factory, the setting is usually performed according to a distance of 100m, in order to facilitate zero marking of the adjusting device after the initial zeroing is performed on the sighting telescope, that is, the zero marking 323 on the adjusting device is aligned with the reference marking preset on the fixing device such as the sighting telescope fixing device, in this embodiment, as shown in fig. 2, the hand wheel device 32 includes a hand wheel body 321 and a zeroing adjusting piece 322 detachably connected with the hand wheel body 321, the hand wheel body 321 and the zeroing adjusting piece 322 share a shaft, the first connecting portion 34 is disposed on the outer surface of the zeroing adjusting piece 322, the accommodating hole 33 is disposed at the bottom of the zeroing adjusting piece 322, and the zeroing adjusting piece 322 is in threaded connection with the first connecting post 31 through the accommodating hole 33. Specifically, the hand wheel body 321 is provided with the zero mark 323, when initial zeroing is required, the hand wheel body 321 is connected with the zeroing adjusting piece 322, so that the hand wheel body 321 does not rotate along with rotation of the zeroing adjusting piece 322, then the zeroing adjusting piece 322 is rotated, the hand wheel body 321 and the zeroing adjusting piece 322 can move along the length direction of the first connecting column 31 by means of engagement of threads, and accordingly the bracket body 1 connected to the first connecting portion 34 or the sighting device mounted on the bracket body 1 is driven to move together, distance compensation adjustment is performed on the sighting device, after the mark center of the sighting device coincides with a set impact point or a target center of a target, the zero mark 323 of the hand wheel body 321 is aligned with a reference mark preset on a fixing device such as the sighting device, then the hand wheel body 321 is assembled and connected with the zeroing adjusting piece 322, and the hand wheel body 321 and the zeroing adjusting piece 322 can rotate together, so that zero marks are completed, and the distance zeroing adjustment is convenient and quick, and can be flexibly applied to zeroing settings of various shooting distances.

It should be noted that, the present embodiment is not limited to the detachable connection manner of the hand wheel body 321 and the zeroing adjustment member 322, as long as the hand wheel body 321 and the zeroing adjustment member 322 can be disassembled according to the requirement. For example, as shown in fig. 1 and fig. 2, in order to facilitate the processing and assembly of the parts and reduce the structural height, the zeroing adjustment member 322 and the hand wheel body 321 are movably sleeved on the first connecting post 31, and the zeroing adjustment member 322 is connected with the hand wheel body 321 in a nested manner, the hand wheel body 321 is provided with at least one first pin 324 facing the zeroing adjustment member 322, the first pin 324 is detachably connected to the hand wheel body 321, and one end of the first pin 324 abuts against the outer side wall of the zeroing adjustment member 322. In this embodiment, the first pin 324 is screwed with the hand wheel body 321, and when the first pin 324 is tightly abutted against the outer side wall of the zeroing adjustment member 322 by tightening the screw, the zeroing adjustment member 322 is connected with the hand wheel body 321 by virtue of the contact friction between the first pin 324 and the zeroing adjustment member 322; the return-to-zero adjustment member 322 may be disconnected from the hand wheel body 321 by unscrewing the first pin 324 from contact with the return-to-zero adjustment member 322. In addition, if the zeroing adjustment piece 322 fails, such as when the screw thread slips, the first pin 324 can be removed, so that the zeroing adjustment piece 322 is separated from the hand wheel body 321, and the zeroing adjustment piece 322 can be replaced, thereby being beneficial to maintenance of parts.

Further, in order to make the connection between the zeroing adjustment member 322 and the hand wheel body 321 more reliable during the rotation process, in this embodiment, as shown in fig. 1 and 2, at least one elongated groove 325 is disposed on an outer side wall of the zeroing adjustment member 322 embedded in the hand wheel body 321, a length of the elongated groove 325 extends along a rotation center line of the zeroing adjustment member 322, and one end of the first pin 324 abuts against an inner wall of the elongated groove 325. Because the inner wall of the strip-shaped groove 325 can block the first pin 324 from sliding along the circumferential direction of the zeroing adjusting piece 322, the zeroing adjusting piece 322 can be prevented from sliding along the circumferential direction in the rotating process of the hand wheel body 321, and the hand wheel body 321 and the zeroing adjusting piece 322 are more reliably connected. In order to facilitate the assembly of the first pin 324 and the elongated groove 325, in this embodiment, the elongated groove 325 is plural and uniformly distributed along the circumference of the outer sidewall of the hand wheel body 321.

To facilitate the assembly of the first pin 324 with the elongated slot 325, in this embodiment, as shown in fig. 2, an end of the first pin 324 facing the elongated slot 325 is tapered, and a small end of the taper faces the elongated slot 325. The cross section shape of the long strip groove 325 is a structure with a small bottom and a large top, and the taper is relatively matched with the cross section shape of the long strip groove 325, so that the first pin 324 can easily extend into the long strip groove 325 and is abutted against the inner wall of the long strip groove 325 in the screwing process.

As shown in fig. 1 and 2, the outer side wall of the zeroing adjustment member 322 is further provided with an annular groove 327, the rotation center line of the annular groove 327 is parallel to the rotation center line of the zeroing adjustment member 322, the hand wheel body 321 is further provided with at least one second pin 326 facing the annular groove 327, the second pin 326 is in threaded connection with the hand wheel body 321, one end of the second pin 326 is provided with an embedded portion 3261 capable of being embedded in the annular groove 327, and two opposite inner walls of the annular groove 327 are in contact connection with the embedded portion 3261. Because the second pin 326 can slide along the annular groove 327, the second pin 326 does not need to be screwed when zero marking is performed, and the second pin 326 can be utilized to move along the length of the first connecting column 31 along with the zero adjustment piece 322 without rotating the hand wheel body 321. In addition, if the zeroing adjustment piece 322 fails, such as when the screw thread slips, the second pin 326 can be removed, so that the zeroing adjustment piece 322 is separated from the hand wheel body 321, and the zeroing adjustment piece 322 can be replaced, thereby being beneficial to maintenance of parts.

In other embodiments not shown, the handwheel body 321 may be detachably connected to the return-to-zero adjustment member 322 by a latch.

Due to the effects of the machining accuracy and machining errors of the threads, radial clearances exist between the intermeshed threads, which cause radial loosening or wobble between the handwheel device 32 and the first connection post 31 that are connected by the threads, thereby affecting the stability of the handwheel device 32 when rotated and thus the aiming accuracy of the aiming tool connected to the handwheel device 32. To eliminate such loosening or rattling, and further improve the stability of the handwheel device 32 during rotation, in this embodiment, as shown in fig. 1 and 2, the receiving hole 33 further includes a non-threaded hole 332 concentric with the threaded hole 331, and the non-threaded hole 332 is in clearance fit with the first connecting post 31. Specifically, as shown in fig. 1, when the non-threaded hole 332 is in clearance fit with the first connecting post 31, the single-side radial clearance is less than or equal to 0.05mm, and the clearance fit mode is as follows:

(a) The first connecting column 31 comprises a polish rod section 312 matched with a non-threaded hole 332, the non-threaded hole 332 is in clearance fit with the polish rod section 312, and a unilateral radial clearance in clearance fit is smaller than or equal to 0.05mm. Because the fit clearance between the unthreaded hole 332 of the receiving hole 33 and the polish rod section 312 of the first connecting column 31 is smaller, the unthreaded hole 331 of the receiving hole 33 can be restricted from loosening or wobbling radially when engaged with the external thread of the first connecting column 31, so that the stability of the hand wheel device 32 during rotation can be further improved.

(B) The non-threaded hole 332 is in clearance fit with the external thread of the first connecting column 31, and a single-side radial clearance between the inner diameter of the non-threaded hole 332 and the major diameter of the external thread is less than or equal to 0.05mm. Because the clearance between the unthreaded hole 332 of the receiving hole 33 and the external thread of the first connecting post 31 is smaller, the radial looseness or wobble existing when the internal threaded hole 331 of the receiving hole 33 is engaged with the external thread of the first connecting post 31 can be restrained, and the stability of the hand wheel device 32 during rotation can be further improved.

The present embodiment is not limited to the position of the non-threaded hole 332 with respect to the internal threaded hole 331, as long as the non-threaded hole 332 and the internal threaded hole 331 are concentric. For example, the non-threaded hole 332 may be located above the internally threaded hole 331 or below the internally threaded hole 331.

In order to facilitate the contact between the two outer flanges 341 disposed on the outer side wall of the handwheel device 32 and the bracket body 1, and also to prevent loosening or adjustment errors caused by a gap between the outer flanges 341 and the bracket body 1, in this embodiment, as shown in fig. 1 and 2, the handwheel device 32 further includes a handwheel connector 328 coaxially disposed with the handwheel body 321, where the handwheel connector 328 is connected with the handwheel body 321, and the two outer flanges 341 are disposed on the outer side wall of the handwheel connector 328 and the outer side wall of the handwheel body 321, respectively. Specifically, in this embodiment, the hand wheel connecting member 328 and the hand wheel body 321 are movable independently, when the hand wheel device 32 needs to be connected to the bracket body 1 through the first connecting portion 34, the outer flange 341 on the outer side wall of the hand wheel connecting member 328 and the outer flange 341 on the outer side wall of the hand wheel body 321 are respectively connected to the bracket body 1 in contact, for example, the two outer flanges 341 are respectively connected to the top surface and the bottom surface of the bracket body 1 in contact, which is equivalent to clamping the bracket body 1 through the two outer flanges 341, and then the hand wheel connecting member 328 is fixedly connected to the hand wheel body 321, so that the bracket body 1 can move along with the hand wheel device 32 without limiting the rotation of the hand wheel device 32. Such a structure not only facilitates quick installation of the outer flange 341, but also ensures contact connection of the outer flange 341 with the bracket body 1, eliminating a gap between the outer flange 341 and the bracket body 1.

It should be noted that, the connection mode of the hand wheel connector 328 and the hand wheel body 321 is not limited in this embodiment, and the hand wheel connector 328 and the hand wheel body 321 may be fixedly connected after the two outer flanges 341 are respectively connected with the bracket body 1 by moving the relative positions of the hand wheel connector 328 and the hand wheel body 321. For example, in the present embodiment, the hand wheel connector 328 is screwed with the hand wheel body 321, the distance between the hand wheel 45 connector 328 and the hand wheel body 321 is adjusted by the engagement of the threads, so as to adjust the distance between the two outer flanges 341, and after the two outer flanges 341 are respectively connected with the bracket body 1 in contact, the hand wheel connector 328 is fixedly connected with the hand wheel body 321 by using a screw thread adhesive.

In other embodiments not shown, the hand wheel connector 328 and the hand wheel body 321 may also be connected by fasteners after the two outer flanges 341 are respectively connected to the bracket body 1 in contact.

To further improve the stability of the handwheel device 32 during rotation by eliminating loosening or wobble due to radial play during engagement of the threads, in this embodiment, as shown in fig. 1 and 2, the handwheel connector 328 is provided with a non-threaded hole 332 extending through the top and bottom surfaces thereof, and the handwheel connector 328 is in clearance fit with the first connection post 31 through the non-threaded hole 332. It should be noted that, in the present embodiment, the manner of the clearance fit between the non-threaded hole 332 and the first connecting post 31 is the same as the manner of the clearance fit between the non-threaded hole 332 and the first connecting post 31 in the previous embodiment, and reference may be made to the related content in the previous embodiment, which is not repeated here.

In order to make the zeroing adjustment member 322 better drive the bracket body 1 or the sighting device installed on the bracket body 1 to move together during zero marking, in this embodiment, as shown in fig. 1 and 2, the hand wheel body 321 is provided with a protruding block 329 facing the zeroing adjustment member 322, and the top surface and the bottom surface of the zeroing adjustment member 322 are respectively in contact connection with the bottom surface of the protruding block 329 and the top surface of the hand wheel connecting member 328. Thus, when the zeroing adjustment member 322 reciprocates along the length of the first connection post 31, it moves the bracket body 1 or the sight mounted on the bracket body 1 together by pushing against the projection 329 or against the hand wheel connection member 328.

As shown in fig. 3 and 4, at least one embodiment of the present invention provides an optical adjustment hinge structure for connecting a bracket body 1 and a bracket base 2, and enabling adjustment in a single direction (e.g., left and right directions), which includes a second connection post 41 for connecting the bracket base 2, the second connection post 41 being provided with an internal thread through hole, and a center line of the internal thread through hole being perpendicular to a length direction of the second connection post 41; the first adjusting shaft 42 is used for connecting the bracket body 1, the first adjusting shaft 42 is provided with an external thread section 421, and the first adjusting shaft 42 is meshed with the second connecting column 41 through the internal thread and the external thread. Specifically, the second connecting column 41 is fixed, and when the first adjusting shaft 42 rotates clockwise or counterclockwise, the first adjusting shaft 42 can be reciprocally inserted into the second connecting column 41, that is, the first adjusting shaft 42 can move from the left side to the right side of the second connecting column 41, and also can move from the right side to the left side of the second connecting column 41. In addition, the moving direction of the first adjustment shaft 42 may be set by the screw thread rotation direction, and the distance moved by each rotation of the first adjustment shaft 42 may be changed by changing the pitch of the screw thread. Therefore, the first adjusting shaft 42 and the second connecting post 41 are connected in such a way that the first adjusting shaft 42 can move in a fixed amount, so that the first adjusting shaft 42 moves in a stable and precise manner during the reciprocating movement. When the first adjusting shaft 42 moves, the bracket body 1 connected to the first adjusting shaft 42 also moves along with the first adjusting shaft, and at the moment, the sighting device is mounted on the bracket body 1, so that the sighting device is indirectly connected to the first adjusting shaft 42, and the left-right adjustment of the sighting device can be realized, namely, the wind deflection compensation adjustment in the gun correction or return-to-zero setting process is realized, the stroke of the wind deflection compensation adjustment is not limited by the structure of the sighting device, and the wind deflection compensation adjustment can be realized by changing the length of the external thread section 421 allowed to pass through the second connecting column 41.

In an embodiment of the connection between the bracket body 1 and the first adjusting shaft 42, as shown in fig. 3, in order to enable the first adjusting shaft 42 to rotate and drive the bracket body 1 to move along with it, the hinge structure for optical adjustment further includes a second connection portion 43 for connecting with the bracket body 1, the second connection portion 43 is provided with a connection protrusion 431, an annular groove 422 with an opening facing outwards is provided on the outer periphery of the first adjusting shaft 42, the connection protrusion 431 is embedded in the annular groove 422, and the connection protrusion 431 is in contact connection with an inner side wall of the annular groove 422, so that the first adjusting shaft 42 is rotatably connected with the bracket body 1. It should be noted that, the structure of the connection protrusion 431 is not limited in this embodiment, as long as the connection protrusion 431 can be embedded in the annular groove 422 and drive the second connection portion 43 to move along with the first adjustment shaft 42. For example, as shown in fig. 4, the connection protrusion 431 may be an independently movable connection piece, and the connection piece may be first embedded into the annular groove 422, and then fixedly connected with the second connection portion 43, so as to achieve connection between the second connection portion 43 and the first adjustment shaft 42; alternatively, in the embodiment not shown in the drawings, the connection protrusion 431 may be a second pin 326 that is independently movable, the second pin 326 is screwed with the second connection portion 43, and the second pin 326 faces the outer periphery of the first adjusting shaft 42, and the second connection portion 43 and the first adjusting shaft 42 may be positioned first, then the second pin 326 is screwed, so that one end of the second pin 326 is embedded into the annular groove 422 and is in contact with the inner side wall of the annular groove 422, so that the connection between the second connection portion 43 and the first adjusting shaft 42 may be achieved.

In order to eliminate the loosening or rattling phenomenon caused by the radial clearance during the thread engagement, and further improve the stability during the rotation of the first adjusting shaft 42, in this embodiment, as shown in fig. 4, the hinge structure for optical adjustment further includes a first elastic member 44 disposed between the second connecting post 41 and the second connecting portion 43, and two ends of the first elastic member 44 respectively abut against the outer peripheral edge of the second connecting post 41 and the end face of the second connecting portion 43 facing the second connecting post 41. Specifically, since the first adjusting shaft 42 is connected to the second connecting post 41 and the second connecting portion 43, the first elastic member 44 is disposed between the second connecting post 41 and the second connecting portion 43, and the first adjusting shaft 42 is tightly connected to the threads of the second connecting post 41 by the elastic force of the first elastic member 44, so that the threads of the internal and external threads are tightly contacted in the axial direction during the threaded connection, and the phenomenon of loosening or shaking of the threads is eliminated by increasing the friction force between the adjacent threads, thereby further improving the stability of the first adjusting shaft 42 during rotation. Preferably, the first elastic member 44 is a spring, in particular a wave spring.

In order to facilitate the rotation operation of the first adjusting shaft 42, in this embodiment, as shown in fig. 4, the hinge structure for optical adjustment further includes an adjusting hand wheel 45, where the adjusting hand wheel 45 is connected to the first adjusting shaft 42, and the adjusting hand wheel 45 may drive the first adjusting shaft 42 to rotate around the rotation center line of the first adjusting shaft 42. It should be noted that, the present embodiment is not limited to the structure of the adjusting hand wheel 45, as long as the structure of the adjusting hand wheel 45 is beneficial to the rotation operation. For example, the adjusting hand wheel 45 is a cylinder with a diameter larger than that of the first adjusting shaft 42, and the periphery of the cylinder is provided with patterns to increase the grasping friction force during rotation operation, and the adjusting hand wheel 45 is sleeved and connected with the first adjusting shaft 42; or the adjustment handwheel 45 may be a polygonal cylinder. In addition, the connection mode of the adjusting hand wheel 45 and the first adjusting shaft 42 is not limited in this embodiment, as long as the adjusting hand wheel 45 can drive the first adjusting shaft 42 to rotate.

In order to facilitate zero marking of the adjusting device after the initial zeroing of the sighting telescope, and also facilitate machining and assembly of parts, in this embodiment, the adjusting hand wheel 45 is detachably connected to the first adjusting shaft 42, that is, the adjusting hand wheel 45 and the first adjusting shaft 42 may be detached as needed. For example, as shown in fig. 4 and 5, the adjusting hand wheel 45 is sleeved with the first adjusting shaft 42, at least one first pin 324 facing the first adjusting shaft 42 is installed on the adjusting hand wheel 45, the first pin 324 is detachably connected with the adjusting hand wheel 45, and one end of the first pin 324 abuts against the outer side wall of the first adjusting shaft 42. In this embodiment, the first pin 324 is screwed with the adjusting hand wheel 45, and when the first pin 324 is tightly abutted against the outer side wall of the first adjusting shaft 42 by tightening the screw, the first adjusting shaft 42 is connected with the adjusting hand wheel 45 by virtue of the contact friction between the first pin 324 and the first adjusting shaft 42; the first adjustment shaft 42 may be disconnected from the adjustment hand wheel 45 by unscrewing the first pin 324 out of contact with the first adjustment shaft 42.

Further, in order to make the connection between the adjusting hand wheel 45 and the first adjusting shaft 42 more reliable, in this embodiment, as shown in fig. 4 and 5, at least one elongated groove 325 is provided on the outer side wall of the first adjusting shaft 42, which is matched with the adjusting hand wheel 45, the length of the elongated groove 325 extends along the length direction of the first adjusting shaft 42, and one end of the first pin 324 abuts against the inner wall of the elongated groove 325. Because the inner wall of the long strip groove 325 can block the first pin 324 from sliding along the circumferential direction of the first adjusting shaft 42, the first adjusting shaft 42 can be prevented from sliding along the circumferential direction in the process of rotating along with the adjusting hand wheel 45, and the adjusting hand wheel 45 is more reliably connected with the first adjusting shaft 42. In this embodiment, the plurality of elongated grooves 325 are uniformly distributed along the circumference of the outer sidewall of the first adjusting shaft 42.

Further, in order to prevent the adjustment hand wheel 45 from sliding along the length direction of the first adjustment shaft 42 during use, so as to affect the adjustment operation, in this embodiment, as shown in fig. 4 and fig. 5, an annular groove 327 is further provided on the outer side wall of the first adjustment shaft 42, the rotation center line of the annular groove 327 is parallel to the rotation center line of the first adjustment shaft 42, at least one second pin 326 facing the annular groove 327 is further installed on the adjustment hand wheel 45, the second pin 326 is in threaded connection with the adjustment hand wheel 45, an embedded portion 3261 capable of being embedded in the annular groove 327 is provided at one end of the second pin 326, and two opposite inner walls of the annular groove 327 are in contact connection with the embedded portion 3261. Since the second pin 326 is slidable along the annular groove 327, the second pin 326 may not be screwed during zero marking, and the second pin 326 may be used to move with the first adjustment shaft 42 without rotation of the adjustment handwheel 45. In addition, if the adjusting hand wheel 45 fails, the second pin 326 can be removed to separate the first adjusting shaft 42 from the adjusting hand wheel 45, so that the adjusting hand wheel 45 can be replaced, and the maintenance of parts is facilitated.

Or in an embodiment not shown in the figures, the first adjustment shaft 42 is screwed with the adjustment hand wheel 45. Specifically, when the adjusting hand wheel 45 is assembled with the first adjusting shaft 42, the adjusting hand wheel 45 is connected with the first adjusting shaft 42 through threaded engagement, then the first pin 324 is installed on the adjusting hand wheel 45, and the first adjusting shaft 42 is connected with the adjusting hand wheel 45 by means of contact friction between the first pin 324 and the first adjusting shaft 42. The cooperation of the first pin 324 and the elongated groove 325 can prevent the adjusting hand wheel 45 from sliding along the circumference of the first adjusting shaft 42 during use, and the threaded connection can further prevent the adjusting hand wheel 45 from sliding along the length direction of the first adjusting shaft 42 during use.

In other embodiments not shown in the figures, the adjustment hand wheel 45 may be detachably connected to the first adjustment shaft 42 by means of a bolt.

In this embodiment, the initial zero setting of the hinge structure for optical adjustment is as follows: when initial zeroing is needed, the adjusting hand wheel 45 is connected with the first adjusting shaft 42, so that the adjusting hand wheel 45 does not rotate along with the rotation of the first adjusting shaft 42, then the first adjusting shaft 42 is rotated, the adjusting hand wheel 45 is penetrated through the second connecting column 41 in a reciprocating manner by virtue of meshing of threads, the bracket body 1 connected to the second connecting part 43 or the sighting device arranged on the bracket body 1 is driven to move together, wind deflection compensation adjustment is carried out on the sighting device, after the division center of the sighting device coincides with a set impact point or the target center of a target, the zero position mark 323 of the adjusting hand wheel 45 is aligned with a reference mark preset on a fixing device such as a sighting device, then the adjusting hand wheel 45 is assembled and connected with the first adjusting shaft 42, and the adjusting hand wheel 45 and the first adjusting shaft 42 can rotate together, so that zero position marks are completed, and the adjusting hand wheel is convenient and quick, and can be flexibly applied to zeroing setting under various modes.

As shown in fig. 6, in other embodiments of an optical adjustment hinge structure, unlike the above-described embodiments of an optical adjustment hinge structure, the second connection post 41 includes an upper post 411 and a lower post 412 having a common rotation shaft 413, and the upper post 411 and the lower post 412 are rotatable about the common rotation shaft 413, the internal thread through hole is provided in the upper post 411, and a center line of the internal thread through hole is perpendicular to a length direction of the upper post 411 and parallel to a center line of the common rotation shaft 413, and the first adjustment shaft 42 is penetrated through the upper post 411 by internal and external thread engagement.

As shown in fig. 7 to 14, at least one embodiment of the present invention provides a first adjusting bracket for implementing optical adjustment in up-down or left-right directions, which includes a bracket body 1 and a bracket seat 2, wherein the bracket body 1 and the bracket seat 2 are arranged between the upper and lower layers; the present invention also includes a connecting structure for optical adjustment capable of achieving vertical adjustment in the foregoing embodiment, and a hinge structure for optical adjustment capable of achieving horizontal adjustment in the foregoing embodiment. Specifically, as shown in fig. 7 to 10, the lower end of the first connecting post 31 is slidably connected with the rear end of the bracket seat 2, and the lower end of the first connecting post 31 may slide along a direction toward or away from the front end of the bracket seat 2, the first connecting portion 34 of the hand wheel device 32 is rotatably connected to the rear end of the bracket body 1, the second connecting post 41 is mounted at the front end of the bracket seat 2, and the first adjusting shaft 42 is connected to the front end of the bracket body 1, so that the bracket body 1 may be turned around the first adjusting shaft 42 relative to the bracket seat 2 under the driving of the hand wheel device 32 in a certain range. Because the front end of the support body 1 is constrained by the second connecting column 41 and the first adjusting shaft 42, when the hand wheel device 32 drives the support body 1 to reciprocate along the length direction of the first connecting column 31, the support body 1 is actually turned around the first adjusting shaft 42 in a direction away from or close to the support seat 2, and because the lower end of the first connecting column 31 can slide along a direction towards or away from the front end of the support body 1, the external thread center line of the first connecting column 31 can be ensured to be always tangent to the turning track of the support body 1 around the first adjusting shaft 42, so that the zeroing adjusting piece 322 and the first connecting column 31 are prevented from being blocked in the process of threaded engagement. The adjustment stroke of the adjustment bracket may be changed by changing the installation distance between the first connection post 31 and the second connection post 41, and the greater the installation distance between the first connection post 31 and the second connection post 41, the greater the adjustable stroke of the adjustment bracket.

Note that, in this embodiment, the connection manner in which the lower end of the first connection post 31 and the rear end of the bracket seat 2 are slidable is not limited, as long as the connection manner is capable of satisfying that the lower end of the first connection post 31 is slidable in a direction toward or away from the front end of the bracket body 1. For example, as shown in fig. 8, the rear end of the bracket seat 2 is provided with an elongated hole 21 penetrating the top surface and the bottom surface of the bracket seat 2, the length direction of the elongated hole 21 extends towards the front end or the rear end of the bracket seat 2, the long side wall of the elongated hole 21 is provided with a mounting hole for mounting a pin shaft 91, the lower end of the first connecting column 31 is provided with an elongated through hole 311, the length direction of the elongated through hole 311 is perpendicular to the center line of the first connecting column 31, the pin shaft 91 passes through the elongated through hole 311 and then is mounted in the mounting hole, so that the lower end of the first connecting column 31 can slide towards or away from the front end of the bracket body 1 through the elongated through hole 311 after being connected with the rear end of the bracket seat 2; alternatively, in an embodiment not shown in the drawings, the long side wall of the long hole 21 is provided with a slide groove extending in the longitudinal direction toward the front end or the rear end of the bracket base 2, and the lower end of the first connecting post 31 is fitted to the slide groove by a pin 91 and is slidable in the direction along the slide groove toward or away from the front end of the bracket body 1.

In this embodiment, the manner in which the second connection post 41 is mounted on the front end of the holder 2 is not limited as long as the second connection post 41 can be connected to the front end of the holder 2. For example, the second connecting post 41 is fixedly installed at the front end of the support 2, and at this time, the second connecting post 41 is in a fixed state, so that the first adjusting shaft 42 is limited to rotate around the first connecting post 31 with the support body 1, so that the adjusting support can only be adjusted in the up-down direction, that is, the support body 1 can only be turned around the first adjusting shaft 42 in a direction away from or close to the support 2 under the driving of the handwheel device 32, and the state of the support body 1 is that the support body 1 moves upwards or downwards in this process.

As another example, as shown in fig. 11 to 14, the second connection post 41 is rotatably mounted on the front end of the bracket base 2, specifically, the second connection post 41 is rotatably mounted on the front end of the bracket base 2 around its own central axis, and the first adjustment shaft 42 is rotatably connected to the front end of the bracket body 1 around its own central axis. At this time, the second connecting column 41 is in a movably connected state, so that the first adjusting shaft 42 cannot be limited to rotate around the first connecting column 31 with the bracket body 1, and the adjusting bracket can be adjusted in the left-right direction, so that the bracket body 1 can rotate around the first connecting column 31 within a certain range under the driving of the first adjusting shaft 42, and in this process, the bracket body 1 is in a state of moving from the left side to the right side of the second connecting column 41 or from the right side to the left side of the second connecting column 41. The second connecting post 41 may be rotatably mounted on the support base 2, as shown in fig. 8, 12 and 14, where the support base 2 is provided with a connecting post mounting hole 22 and a second pin 326 facing the connecting post mounting hole 22, the center line of the connecting post mounting hole 22 is perpendicular to the bottom surface of the support base 2, the second pin 326 is in threaded connection with the support base 2, an annular groove 327 is provided at the lower end of the second connecting post 41, the lower end of the second connecting post 41 is inserted into the connecting post mounting hole 22, and the second pin 326 penetrates through the inner wall of the connecting post mounting hole 22 and is embedded into the annular groove 327 to limit the second connecting post 41 to move along the center line of the connecting post mounting hole 22, but the second pin 326 does not limit the second connecting post 41 to rotate around its center axis.

The second connecting post 41 may be rotatably mounted on the support base 2, as shown in fig. 18, where the support base 2 is provided with a connecting post mounting hole 22, the inner side wall of the connecting post mounting hole 22 is provided with a boss 221, the boss 221 extends along the center line of the connecting post mounting hole 22, and an upper limiting portion 414 and a lower limiting portion 415 connected with the top and the bottom of the boss 221 in contact with each other are provided at the lower end of the second connecting post 41, which is equivalent to that the upper limiting portion 414 and the lower limiting portion 415 clamp the boss 221 to limit the movement of the second connecting post 41 along the center line of the connecting post mounting hole 22, but not limit the rotation of the second connecting post 41 around the center axis thereof. Further, in order to facilitate the installation of the second connecting column 41 and the connecting column installation hole 22, the lower limiting portion 415 is provided with an internal thread, the lower end of the second connecting column 41 is provided with an external thread, when the second connecting column 41 is installed in the connecting column installation hole 22, the lower end of the second connecting column 41 is inserted into the connecting column installation hole 22, the upper limiting portion 414 is in contact connection with the top of the boss 221, then the lower limiting portion 415 is connected with the lower end of the second connecting column 41 through threaded engagement, the lower limiting portion 415 is in contact connection with the bottom of the boss 221, and finally the lower limiting portion 415 is fixed at the lower end of the second connecting column 41 through a threaded adhesive.

In this embodiment, as shown in fig. 8 and 10, the adjusting bracket further includes a second elastic member 92 disposed between the bracket base 2 and the bracket body 1, and two ends of the second elastic member 92 respectively abut against the bracket base 2 and the bracket body 1. Specifically, because the hand wheel device 32 is in threaded connection with the first connecting column 31, and meanwhile, the hand wheel device 32 is also connected with the bracket body 1, the second elastic piece 92 is arranged between the bracket seat 2 and the bracket body 1, and the threaded connection between the hand wheel device 32 and the first connecting column 31 is tensioned through the elastic force of the second elastic piece 92, so that the threads of the internal and external threads are in closer contact in the axial direction during the threaded connection, the phenomenon of loosening or shaking of the threads is eliminated by increasing the friction force between the adjacent threads, and the stability of the hand wheel device 32 during rotation is further improved. Preferably, the second elastic member 92 is a spring.

Further, as shown in fig. 8 and 10, the second elastic member 92 is sleeved on the first connecting post 31, and two ends of the second elastic member 92 are respectively abutted against the bracket seat 2 and the hand wheel device 32, so as to prevent the second elastic member 92 from being separated from the bracket seat 2 or the bracket body 1 due to vibration in the use process of the adjusting bracket, and meanwhile, the first connecting post 31 can guide the movement direction of the second elastic member 92 when compressing or extending, so that the second elastic member 92 compresses or extends along the length direction of the first connecting post 31.

In this embodiment, as shown in fig. 8 and 10, the top of the bracket body 1 is provided with a mounting plane 11 for mounting the sighting telescope, and the central axis of the first connecting column 31 is perpendicular to the mounting plane 11, which is beneficial to assembly of parts. The rear end of the bracket body 1 is provided with a hand wheel installation through hole 12 penetrating through the top surface and the bottom surface of the bracket body 1, the hand wheel body 321 and the hand wheel connecting piece 328 are both inserted into the hand wheel installation through hole 12, and two outer flanges 341 respectively arranged on the outer side wall of the hand wheel connecting piece 328 and the outer side wall of the hand wheel body 321 are respectively in contact connection with the top surface of the bracket body 1 and the bottom surface of the bracket body 1. The hand wheel mounting through hole 12 can limit the hand wheel body 321 and the hand wheel connecting piece 328 to move along the radial direction, so that the outer flange 341 is prevented from being separated from the bracket body 1 due to vibration in the use process of the adjusting bracket.

In this embodiment, as shown in fig. 15 (only the optical adjustment connection structure, the support body and the telescopic protrusion are shown in the drawing), the adjustment support further includes a first hand feeling enhancement mechanism, where the first hand feeling enhancement mechanism includes a plurality of recesses 35 (see fig. 1) arranged at intervals along the outer side wall periphery of the hand wheel device 32, and at least one telescopic protrusion 51 fixedly disposed on the support body 1 and adapted to the recesses 35, and the recesses 35 can rotate with the hand wheel device 32. Specifically, the recess 35 is alternatively disposed on the outer side wall of the hand wheel body 321 or the outer side wall of the hand wheel connector 328, and the telescopic protrusion 51 abuts against the inner wall of the recess 35.
