Referring to fig. 1 to 3, the head according to the embodiment of the present invention includes a main body shaft 10, a head cover 20, a sprocket 30, and a driving device. The main body shaft 10 penetrates through the head cover 20, the chain wheel 30 is installed on the main body shaft 10 in a rolling way through the deep groove bearing 31, and the locking cap 34 is arranged at the top end of the main body shaft 10, so that the parts on the main body shaft 10 cannot be separated from the main body shaft 10. The sprocket cover 32 covers the end face of the sprocket 30, and the driving device is connected to the top end of the head cover 20 through a clutch device. The sprocket 30 is connected to the drive means so that when the sprocket 30 rotates it can drive the drive means, causing the drive means to control the clutch means and thus the brake cover 20.
Referring to fig. 4 to 7, a driving device is mounted on the main body shaft 10, the driving device including an outer driving sleeve 40 and an inner driving sleeve 50, the outer driving sleeve 40 being rotatably sleeved outside the inner driving sleeve 50, a base 42 of the outer driving sleeve 40 being provided with a second engagement portion, the outer driving sleeve 40 being connected to the sprocket 30 through the second engagement portion, the sprocket 30 being capable of driving the outer driving sleeve 40. The drive device is also located in the head cover 20, and a needle bearing 33 is arranged between the drive device and the head cover, so that the drive device and the head cover can move independently of each other. The top end of the side wall of the outer driving sleeve 40 is provided with a first groove 411, the top end of the side wall of the inner driving sleeve 50 is provided with a second groove 51, a position-changing groove is formed at the inner and outer overlapped and opposite part of the first groove 411 and the second groove 51, and the clutch device is abutted with the position-changing groove. When the outer driving sleeve 40 and the inner driving sleeve 50 relatively rotate, the area where the first groove 411 and the second groove 51 overlap changes, so that the depth of the displacement groove changes, and the clutch device moves along the axial direction along with the change of the depth of the displacement groove due to the abutment of the clutch device and the displacement groove.
Preferably, the first groove 411 and the second groove 51 are V-shaped grooves, and the areas of the first groove 411 and the second groove 51 are equal. Since the first groove 411 and the second groove 51 are both V-shaped grooves, the displacement grooves are also V-shaped grooves, so that when the outer driving sleeve 40 rotates relative to the inner driving sleeve 50, the clutch device moves more continuously and smoothly along with the displacement grooves, and the phenomenon of jamming during the movement of the clutch device is avoided. In addition, the deflection groove is a V-shaped groove, so that the clutch device can be better clamped in the deflection groove and cannot be separated when the driving device rotates, and the motion connection is disconnected.
Further, in order to make the stress of the clutch device more uniform and reduce the probability of the clutch device shifting during the movement process, the driving device is provided with a plurality of shifting grooves, namely the outer driving sleeve 40 is provided with a plurality of first grooves 411, correspondingly, the inner driving sleeve 50 is provided with a plurality of second grooves 51, and the first grooves 411 and the second grooves 51 are in one-to-one correspondence; the deflection grooves are arranged at equal intervals to ensure that the clutch device is uniformly stressed.
The clutch device comprises a clutch sleeve 81 and a spring 82, one end of the spring 82 is abutted on the clutch sleeve 81, the other end of the spring 82 is abutted on the inner top of the brake cover 20, and preferably, gaskets are arranged at two ends of the spring 82. The end surface of the clutch sleeve 81 away from the top of the head cover 20 is provided with an abutting portion abutting against the shifting groove, and preferably, the abutting portion includes at least one abutting column abutting against the bottom of the shifting groove. In an embodiment, the abutment portion includes a plurality of abutment posts, and each of the abutment posts is equidistantly spaced along a circumferential direction of the clutch sleeve. Further, the clutch cover 81 has a first engagement portion provided on an end surface thereof adjacent to the top of the head cover 20, which is engageable with the head cover 20. When the outer driving sleeve 40 and the inner driving sleeve 50 rotate relatively and the depth of the shifting groove is reduced, the clutch sleeve 81 is driven by the driving device to move along the axial direction of the main body shaft 10 near the top of the head cover 20 due to the abutting part of the clutch sleeve 81 abutting against the shifting groove, and the spring 82 is compressed while moving until the first meshing part of the clutch sleeve 81 is meshed with the inner top of the head cover 20, at this time, the sprocket 30 is linked with the head cover 20 through the driving device and the clutch sleeve 81, so that the head cover 20 can be driven to rotate. When the driving device is reset, the depth of the shifting groove is restored, and the clutch sleeve 81 is far away from the top of the head cover 20 under the action of the spring 82, so that the sprocket 30 is restored to a state of moving independently of the head cover 20.
Referring to fig. 4 to 6, a reset mechanism is further provided between the outer driving sleeve 40 and the inner driving sleeve 50, an opening 53 and a positioning slot 52 opposite to the opening 53 are provided on a side wall of the inner driving sleeve 50, the reset mechanism includes two reset torsion springs 70 arranged in opposite directions, a first end pin of each reset torsion spring 70 is fixed on the positioning slot 52, a reset space 71 is formed between a second end pin of each reset torsion spring 70, the outer driving sleeve 40 is provided with a protruding rib 421, and the protruding rib 421 can be matched with the reset space 71. Optionally, the outer driving sleeve 40 includes a sleeve body 41 and a base 42, a notch is provided at the bottom of the sidewall of the sleeve body 41, a stop block is provided on the edge of the base 42, the stop block is adapted to the notch, the protruding rib 421 is located on the inner side of the stop block, and correspondingly, the positioning groove 52 is located on the sleeve body 41. Because the outer driving sleeve 40 is mainly formed by assembling the sleeve body 41 and the base 42, the reset torsion spring 70 or other components are convenient to be installed. After the two return torsion springs 70 are reversely mounted into the sleeve 41, the stoppers are corresponding to the notches to mount the base 42 to the sleeve 41. The convex rib 421 on the stop block is clamped into the reset space 71, when the outer driving sleeve 40 rotates in one direction, the convex rib 421 pushes the end pin of one reset torsion spring 70 until the convex rib 421 contacts the side wall of the opening 53, and the outer driving sleeve 40 and the inner driving sleeve 50 rotate integrally; when the sprocket 30 stops rotating, the sprocket 30 does not exert force on the outer driving sleeve 40, at this time, the reset torsion spring 70 resets under the action of elastic potential energy, the outer driving sleeve 40 is reset by the convex rib, and then the shifting groove returns to the original state, and the clutch sleeve 81 is separated from engagement with the head cover 20. Since the two return torsion springs 70 are disposed in opposite directions, the above-described process can be repeated when the outer driving sleeve 40 rotates in the other direction, i.e., the other return torsion spring 70 can return it.
Further, a locking mechanism is provided between the outer drive sleeve 40 and the inner drive sleeve 50. The locking mechanism comprises at least one locking torsion spring 60, two end feet of the locking torsion spring 60 extend out of the opening 53, and the two end feet of the locking torsion spring 60 are respectively opposite to two sides of the opening 53 one by one. The main body shaft 10 penetrates all the locking torsion springs 60, and the locking torsion springs 60 are clasped on the main body shaft 10 in a natural state. When the outer driving sleeve 40 rotates relative to the inner driving sleeve 50, the protruding ribs 421 rotate relative to the inner driving sleeve 50 until the protruding ribs 421 are abutted against the side walls of the openings 53 to directly drive the inner driving sleeve 50 to rotate, and then the other side of the openings 53 of the inner driving sleeve 50 is abutted against the end feet of the locking torsion springs 60, so that the locking torsion springs 60 are opened, and the friction force of the locking torsion springs 60 tightly held on the main shaft 10 is reduced, so that the aim that the inner driving sleeve 50 can synchronously rotate along with the outer driving sleeve 40 is fulfilled. Since the locking torsion spring 60 is held tightly on the main body shaft 10 with its two end legs respectively opposed to the two side walls of the opening 53, the sprocket 30 can be kept stationary and stable without being pulled.
Preferably, to reduce the interaction between the return torsion spring 70 and the locking torsion spring 60, a spacer 61 may be provided between the return torsion spring 70 and the locking torsion spring 60.
The embodiment of the invention provides a bead pulling hand-push roller shutter, which comprises a shutter body, a tail making device, a bead pulling device, a roller tube and the head making device, wherein the shutter body is wound on the roller tube, two ends of the roller tube are respectively connected with the head making device and the tail making device, and the roller tube is also connected with a spring system.
The operating principle of the bead pulling hand-push roller shutter is as follows: when the curtain is lowered or raised to an unsuitable height, the pull beads may be pulled and the pull beads drive the sprocket 30 to rotate. Because the sprocket 30 is engaged with the base 42, the outer drive sleeve formed by the base 42 and the sleeve 41 is also rotated integrally therewith. The convex rib 421 on the base 42 rotates in the reset space 71, and after rotating, the convex rib 421 is abutted against one side wall of the opening 53 of the inner driving sleeve 50, so as to drive the inner driving sleeve 50 to rotate; at the same time, the first groove 411 on the outer driving sleeve 40 and the second groove 51 on the inner driving sleeve 50 are offset from each other, so that the depth of the formed displacement groove is reduced, and thus the clutch sleeve 81 moves closer to the top of the head cover 20 in the axial direction of the main body shaft 10. The clutch sleeve 81 moves, the spring 82 is compressed, the clutch sleeve 81 moves to be meshed with the inner top of the head cover 20, and at the moment, the chain wheel drives the head cover 20 to rotate by driving the outer driving sleeve 40 and the clutch sleeve 81, so that the retraction of the upper curtain body of the roller tube can be controlled.
When the curtain is put in place, the pull beads are loosened. The outer driving sleeve 40 is not acted by the chain wheel 30 at this time, and the convex rib 421 drives the whole outer driving sleeve 40 to reset under the action of the reset torsion spring 70. The displacement groove formed on the driving device is restored to the original state, and the depth of the displacement groove is increased. The clutch sleeve 81 is always in contact with the bottom of the displacement groove by the action of the spring 82, so that the clutch sleeve is far away from the inner top of the head cover 20, and the clutch sleeve 81 is disconnected from the head cover 20. At this time, the movement of the head cover is controlled by the rolling tube and the spring system, so that the function of pushing the rolling shutter is realized.
While the preferred embodiments of the present application have been illustrated and described, the present application is not limited to the embodiments, and various equivalent modifications and substitutions can be made by one skilled in the art without departing from the spirit of the present application, and these equivalent modifications and substitutions are intended to be included in the scope of the present application as defined in the appended claims.
