Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; either directly, indirectly, through intermediaries, or in communication with each other. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.

In order to facilitate that the handle in the door is not linked with the handle outside the door, the aim that the handle in the door and the handle outside the door independently act and are not influenced by each other is fulfilled; the invention provides a non-linkage lock body of another conception. The method comprises the following steps:

fig. 1 shows a non-interlocking lock body according to a preferred embodiment of the present invention, comprising a housing 1, a driving mechanism 2, a clutch assembly 3, and a main lock tongue assembly 4.

Referring to fig. 2, the main latch assembly 4 includes a movable member 41, a lever 42 and a main latch 43 mounted (fixed or elastically connected by a spring) on the movable member 41, the main latch 43 is movably inserted into the housing 1, the lever 42 is pivotally connected to the housing 1 near a first end of the clutch assembly 3 (see also fig. 1), one of a second end of the lever 42 away from the clutch assembly 3 and the movable member 41 is provided with a guide groove 421, and the other is provided with a guide post 411. When the lever 42 swings relative to the housing 1, the guide post 411 moves relative to the guide slot 421 along the length direction of the guide slot 421 (the length direction of the guide slot 421 is perpendicular to the depth direction thereof, i.e., the slot depth direction according to common knowledge), so that the moving member 41 moves linearly, and the main lock tongue 43 expands and contracts relative to the housing 1.

For ease of understanding, please refer to fig. 4-7. Referring specifically to fig. 4, the clutch assembly 3 includes a first rotary seat 31, a second rotary seat 32, and a linkage seat 33 all coaxially arranged. The first rotating seat 31 and the second rotating seat 32 are respectively provided with a hole site, a boss or a slot 34 for installing a handle. The linkage seat 33 has a collar 331, the first rotating seat 31 is inserted along a first end of the collar 331 and movably sleeved with the inner ring 3311 of the collar, and the second rotating seat 32 is inserted along a second end of the collar 331 and movably sleeved with the inner ring 3311 of the collar. Referring to fig. 6, the collar 331 is radially provided with a through hole 332, a first return spring 333 is embedded in the through hole 332, a clutch pin 334 is inserted in the through hole 332, and the first return spring 333 is sleeved with the clutch pin 334 and causes the clutch pin 334 to have a movement trend away from the axis of the collar 331 along the radial direction of the collar 331 in a natural state.

Referring to fig. 7, the linkage seat 33 is further provided with a selection linkage member 35, the first rotation seat 31 is radially protruded to form a first selected linkage portion 311, and the second rotation seat 32 is radially protruded to form a second selected linkage portion 321. Only one of the first selected linkage part 311 and the second selected linkage part 321 can toggle the selected linkage member 35 so as to reversely rotate the linkage seat 33 around the axis thereof; the other is provided with a first notch 3111 for accommodating the clutch pin 334 at a corresponding position of the clutch pin 334, and the clutch pin 334 is located outside the first notch 3111 in a natural state. That is, only one of the first selected linkage portion 311 and the second selected linkage portion 321 must be located at a position where the selection linkage member 35 can be moved so that the selection linkage member 35 can be moved when the first selected linkage portion rotates, and the other one cannot move the selection linkage member 35 under the condition of idle rotation, that is, the other one can move the linkage member after being matched with the first notch 3111 through the clutch pin 334. Thus, one of the first rotating seat 31 and the second rotating seat 32 can be driven to rotate unconditionally in the door, a series of door opening actions are realized, and the other is not linked during operation; the other can control the linkage shaft to rotate on the premise that the clutch pin 334 is inserted into the first notch 3111, so as to independently realize the door opening action.

Referring to fig. 2, the driving mechanism 2 is configured to drive the clutch pin 334 to be inserted into the first notch 3111.

It should be noted here that, for ease of understanding:

Definition: in fig. 1-9, the clockwise direction is the forward direction and the counterclockwise direction is the reverse direction. That is, when the device rotates clockwise along the view angle of fig. 1-9, the device rotates forward; when rotated clockwise along the view of fig. 1-9, it is rotated in the opposite direction.

The linkage seat 33 protrudes along the axial direction perpendicular to the linkage seat itself to form a first shifting block 335 (see fig. 2), and when the linkage seat 33 rotates in a reverse direction relative to the axis of the linkage seat itself, the first shifting block 335 can press the first end of the shifting lever 42, so that the shifting lever 42 swings to drive the main lock tongue 43 on the moving member 41 to retract.

Referring to fig. 4, and in combination with fig. 2, when the first rotating seat 31 rotates forward around its own axis, the first selected linkage 311 (see fig. 2 or fig. 7) presses the first end of the lever 42, so that the lever 42 swings to drive the main lock tongue 43 on the moving member 41 to extend; and when the second rotating seat 32 rotates around its own axis in the forward direction, the second selected linkage 321 (see fig. 7) presses the first end of the shift lever 42, so that the shift lever 42 swings to drive the main lock tongue 43 on the moving member 41 to extend.

Obviously, the non-linkage lock body of the present embodiment achieves the purpose of independently controlling the rotation of the linkage seat 33 by the first rotation seat 31 and the second rotation seat 32 on the basis of using the clutch assembly 3. That is, when the first rotating seat 31 controls the linkage seat 33 to rotate, the second rotating seat 32 is in a static state; when the second rotating seat 32 controls the linkage seat 33 to rotate, the first linkage seat 33 is in a static state. By the arrangement, the linkage between the door inner handle and the door outer handle can be avoided. On the basis, the first rotating seat 31 and the second rotating seat 32 rotate the linkage seat 33, so that the shift lever 42 is shifted by the linkage seat 33 to unlock (namely, the shift lever 42 drives the main lock tongue 43 to unlock); the locking of the main bolt 43 can be achieved independently when the first rotating seat 31 and/or the second rotating seat 32 rotate forward (i.e. the main bolt 43 is driven by the driving lever 42 to extend out of the housing 1 for locking). In addition, one of the first selected linkage part 311 and the second selected linkage part 321, which can select the linkage 35, can realize the unconditional control of the rotation of the linkage seat 33 (that is, the precondition that the release pin 334 is not required to be inserted into the first notch 3111 is not required), and the other precondition that the release pin 334 is required to be inserted into the first notch 3111 is required, so that the purposes of unconditionally unlocking the door and satisfying the condition outside the door to open the door are realized. The clutch is compact in structure and convenient to manufacture, so that the manufacturing of the non-linkage lock body is facilitated, and the control mode is reliable.

It should be noted here that, in the actual application process, the operation of the driving mechanism 2 may be implemented based on the existing mature wired or wireless control technology, so that the driving mechanism 2 may drive the release pin 334 to be inserted into the first notch 3111.

In addition, it should be further explained that, in fig. 2, the moving member 41 is used as a part for linking the main bolt 43, and the main bolt 43 can be extended or contracted mainly by linear motion, and the specific structure of the moving member 41 may be a thin plate structure or a regular or irregular structure, that is, the specific structure has no substantial influence. In fig. 2, in the cooperation between the guide groove 421 and the guide post 411, the guide groove 421 may have a closed-loop structure or an open-loop structure, or may be formed of two blocks spaced apart from each other, so long as the guide groove can be linearly guided; the guide post 411 may be a portion formed by protruding one of the lever 42 or the movable member 41, or may be a component fixed to the lever 42 or the movable member 41 by fixing or removing. Obviously, the structure is only required to realize that the guide groove 421 and the guide post 411 control the extension and retraction of the main bolt 43. In addition, it should be mentioned that the driving mechanism 2 may be a combination of screw rods of the motor 21, or the motor 21 drives a transmission belt or a chain to drive a pressing block to press the clutch pin 334, and obviously, the selection of the driving mechanism 2 is not limited.

In order to further optimize the technical scheme:

Preferably, referring to fig. 4 and 7, a first notch 3111 is provided in the first rotating seat 31, a second notch 3211 for accommodating the clutch pin 334 is provided in the second rotating seat 32 at a position corresponding to the clutch pin 334, the first notch 3111 and the second notch 3211 are combined to form a composite notch 336 for accommodating the clutch pin 334, and the driving mechanism 2 is used for driving the clutch pin 334 to be inserted into the composite notch 336. The selection link 35 is detachably connected to the link seat 33, so that the selection link 35 can be moved by the first selected link portion 311 or the second selected link portion 321. In this way, as long as the clutch pin 334 is inserted into the synthesis notch 336, the first rotating seat 31 or the second rotating seat 32 can independently drive the linkage seat 33 to rotate, so as to realize the unlocking and door opening actions; therefore, after the non-linkage lock body is installed on the front or back according to the actual situation (such as according to the direction of the handle), the selection linkage member 35 is only required to be detached and then detachably installed, so that the non-linkage lock body can be driven by one of the first rotating seat 31 and the second rotating seat 32, and the other non-linkage lock body can realize the driving of the linkage seat 33 on the basis of the cooperation of the separation pin 334 and the synthesis notch 336. By the arrangement, the non-linkage lock body has stronger universality, and can be suitable for different door structures and different handle orientations.

Preferably, the selective linkage member 35 has a threaded section, the linkage seat 33 is provided with a threaded through hole 332 in threaded engagement with the threaded section, or the linkage seat 33 is symmetrically provided with two threaded blind holes in threaded engagement with the threaded section. Obviously, the parts with threaded segments have screws, bolts, jackscrews, studs, etc. However, the linkage member 35 can be selected to be detachably connected in a threaded connection manner, and other conventional technical means such as clamping, simple plugging and the like can be directly adopted; or may be a combination of plugging and clamping. But the threaded connection mode is obviously convenient for installation and disassembly, and the fixing mode is firm and safe.

Preferably, referring to fig. 1, the housing 1 is provided with a first stroke limiting hole 11 and a second stroke limiting hole (not shown in the figure) which are symmetrical to each other at two opposite sides of the housing, the first rotating seat 31 is provided with a first limiting portion 312 (referring to fig. 2), and the second rotating seat 32 is provided with a second limiting portion (not shown in the figure); the first limiting portion 312 is adapted to the first travel limiting hole 11 to limit a limiting angle of the first limiting portion 312 swinging around the axis of the first rotating seat 31, and the second limiting portion is adapted to the second travel limiting hole to limit a limiting angle of the second limiting portion swinging around the axis of the second rotating seat 32.

Preferably, referring to fig. 1, the non-interlocking lock body further comprises a tongue assembly 5 and a tongue blade 6. Referring to fig. 2, the latch assembly 5 includes a latch 51, a moving rod 52 fixedly connected to the latch 51, and a second return spring 53 sleeved on the moving rod 52. The two ends of the second return spring 53 are respectively abutted against the inclined tongue 51 and the shell 1, and the second return spring 53 is used for driving the inclined tongue 51 to extend out of the shell 1. The end of the moving rod 52 far away from the inclined tongue 51 is provided with a limiting block 54. The tongue blade 6 (see fig. 1) is pivotally connected to the housing 1, the tongue blade 6 is located on one side of the clutch assembly 3, and the rotation axis of the tongue blade 6 is arranged coaxially with the axis of the first rotating seat 31. The tongue pulling piece 6 is formed in a radially protruding manner along its own axis and is provided with a second pulling block 61 and a third pulled block 62 which are arranged at intervals along the circumference of the own axis of the tongue 51. The linkage seat 33 protrudes along its own axis to form a fourth shifting block 36 (as will be understood in detail with reference to fig. 2 and 3, the fourth shifting block 36 is used to press the third shifted block 62 to rotate the third shifted block 62 in the opposite direction). The second block 61 abuts against the stopper 54, and the third block 62 abuts against the fourth block 36; when the linkage seat 33 (see fig. 4, in which the linkage seat 33 is driven by the first rotating seat 31 or the second rotating seat 32) rotates reversely around the own axis, the fourth shifting block 36 shifts the third shifted block 62 to make the latch tongue shifting piece 6 rotate along with the linkage seat 33, and then makes the second shifting block 61 shift the limiting block 54 to make the latch tongue 51 shrink. It should be additionally explained here that the latch assembly 5 and the latch blade 6 are automatically reset by the second reset spring 53. This arrangement allows the linkage seat 33 to rotate in reverse and simultaneously allows the latch plate 6 to rotate in reverse to unlock the latch 51 (even if the latch 51 is retracted). In this way, one-step opening of the door (i.e., simultaneous opening of the latch 51 and the main latch 43 can be achieved by the linkage mount 33) can be achieved.

Preferably, referring to fig. 2, the driving mechanism 2 includes a motor 21, a driven shaft 22 drivingly connected with the motor 21, a movable seat 23 movably sleeved on the driven shaft 22, and a transmission spring 24 sleeved on the driven shaft 22. The transmission spring 24 is fixed on the movable seat 23, the driven shaft 22 radially protrudes with a transmission rod 25, and the transmission rod 25 passes through the transmission spring 24 along the radial direction so as to drive the transmission spring 24 to move along the axial direction of the driven shaft 22. The movable seat 23 has a pressing portion for pressing the clutch pin 334. Obviously, under the rotation of the driven shaft 22, the transmission rod 25 rotates synchronously with the driven shaft 22, forcing the spring to move, so that the pressing part of the movable seat 23 presses or releases the clutch pin 334.

More preferably, the driving mechanism 2 further comprises a driving gear 27 in driving connection with the motor 21 and a driven gear 26 in driving connection with the driving gear 27, and the driven shaft 22 is fixedly connected with the driven gear 26. Obviously, the reduction of the speed of the movable seat 23 can be realized by the cooperation of the driving gear 27 and the driven gear 26, and the rigid collision is alleviated.

Preferably, referring to fig. 8, the non-interlocking lock body further comprises a torsion member 7 and a locking mechanism 8. Referring to fig. 9, the linkage seat 33 radially protrudes to form a fifth dial 37, and the torsion member 7 radially protrudes to form a sixth dialed block 71 and a seventh dialed block 72. The fifth dial 37 abuts against the sixth dialed block 71, and the fifth dial 37 is used for driving the sixth dialed block 71 to rotate in the reverse direction. The locking mechanism 8 comprises a locking moving plate 81 and a locking cylinder 82 arranged on the locking moving plate 81, a locking groove 412 is formed in the moving member 41 of the main lock tongue assembly 4, and the locking cylinder 82 is used for locking the locking groove 412. The seventh dial 72 abuts against the locking moving piece 81 and serves to drive the locking moving piece 81 to move so that the locking cylinder 82 is disengaged from the locking groove 412. So configured, when the first rotating seat 31 or the second rotating seat 32 drives the linkage seat 33 to reversely rotate to unlock the main bolt 43 and the oblique bolt 51, the locking cylinder 82 can be driven by the locking moving piece 81 to disengage from the locking groove 412, so that the locking cylinder 82 is prevented from locking the moving piece 41 (see fig. 2) of the main bolt assembly 4 (i.e. avoiding the shrinkage of the interference moving piece 41).

Preferably, the locking mechanism 8 further includes a third return spring for driving the locking cylinder 82 into the locking groove 412. In this way, the lock cylinder 82 is fitted into the lock groove 412 in a natural state. Therefore, when the non-linkage seat 33 is driven, the moving member 41 (see fig. 2) is locked, i.e. the moving member 41 is prevented from being retracted, so that the main lock tongue 43 cannot be unlocked, and the anti-theft effect is better.

The third reset elastic piece is a torsion spring, a spring (namely a compression spring or a tension spring), a belt or a rubber belt and the like.

The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
