furthermore, a support body 21 which supports the pressing member 4 is bent at the upper part of the clamping member 2, and a clamping body 22 which is clamped with the teeth 11 on the reel 1 is arranged at the lower part of the clamping member 2.
Further, the lower portion of the pressing member 4 is provided with an accommodating groove 41 for accommodating the abutting body 21, and the tail end of the accommodating groove 41 is provided with a blocking protrusion 42.
The clamping part 2 is hinged to the side wall of the tractor shell 6 through the first cylindrical pin 7, meanwhile, the abutting body 21 at the upper part of the clamping part 2 is accommodated in the accommodating groove 41 at the lower part of the pressing part 4, meanwhile, the stopping lug 42 is fixed at the tail end of the accommodating groove 41 to limit the front-back movement of the abutting body 21, the abutting body 21 is prevented from falling off from the accommodating groove 41 in the rotating process of the clamping part 2, and the continuity of the advancing and resetting movement of the clamping part 2 is ensured.
furthermore, when the pressing piece 4 is pressed, the pressing piece 4 pushes the clamping piece 2 to rotate on the first cylindrical pin 7, then the lower part of the clamping piece 2 is inserted into the reel 1, the clamping body 22 on the clamping piece 2 is clamped with the tooth 11 on the reel 1, so that the reel 1 is braked, and the reel 1 is prevented from further rotating. The teeth 11 on the reel 1 are arranged in an annular array, an insertion space 111 is arranged between every two adjacent teeth 11, the distance of the insertion space 111 is twice the width of the clamping body 22, so that the lower part of the clamping part 2 can be inserted into the reel 1, the success rate of braking is improved, more collision between the lower part of the clamping part 2 and the teeth 11 on the reel 1 is prevented, and the service life of parts is prolonged.
Furthermore, a stop wall 62 is disposed on one side of the sidewall of the retractor housing 6, which is located on the first cylindrical pin 7, the elastic element 3 is sleeved on the first cylindrical pin 7, one end of the elastic element 3 abuts against the stop wall 62, and the other end abuts against the inner wall of the locking element 2.
during normal traction, the elastic part 3 is in an open state, one end of the elastic part 3 abuts against the abutting wall 62, and the other end abuts against the inner wall of the clamping part 2, so that the lower part of the clamping part 2 is far away from the reel 1, namely, the reel 1 keeps a rotating state.
When braking, external force pushes the pressing piece 4 and the clamping piece 2, the clamping piece 2 is clamped with the wire wheel 1 so as to promote the wire wheel 1 to stop rotating, and meanwhile, the clamping piece 2 extrudes the elastic piece 3 so as to compress the elastic piece 3 to generate elastic potential energy; after the external force is lost, the elastic piece 3 releases elastic potential energy, and then the clamping part 2 and the pressing piece 4 are pushed, so that the lower part of the clamping part 2 is far away from the reel 1, namely the reel 1 keeps a rotating state.
Referring to fig. 3, a sliding block 53 is disposed in the middle of the push button 5, the pressing member 4 is provided with a sliding groove 43 for the sliding block 53 to slide forward and backward, and the sliding block 53 is provided with an anti-slip strip 531 for preventing the push button 5 from falling off from the sliding groove 43.
The utility model discloses a slider 53 with spout 43 will push away button 5 with pressing part 4 is constituteed as an organic wholely, still adds simultaneously anticreep strip 531, job stabilization nature and smooth and easy nature of operation are good. When the push button 5 and the pressing piece 4 are in the initial positions, the reel 1 keeps rotating, the push button 5 and the pressing piece 4 are pressed, and then the clamping piece 2 is pushed to be clamped with the reel 1, so that the reel 1 is prompted to stop rotating. When the clamping part 2 moves downwards to the right position and simultaneously the push button 5 is pulled backwards, the sliding block 53 slides backwards in the sliding groove 43, so that the locking hook 52 on the push button 5 is abutted with the locking block 61 to promote the locking of the reel 1. Due to the adoption of the structural design, namely the push button 5 is matched with the pressing piece 4, the pressing piece 4 is matched with the clamping stop piece 2, and the push button 5 is matched with the locking block 61, the three working states of starting, suspending and locking the wire wheel 1 are realized, the use is convenient, the operation is convenient, and the braking reliability is high.
the toggle block 51 plays a role in unlocking and locking the reel 1 through the mutual matching of the locking hook 52 at the lower part and the locking block 61. Preferably, the dial block 51 is provided with a rear dial portion 511 for dialing backwards and a front push portion 512 for pushing forwards, a plurality of anti-slip bumps 5111 are uniformly arranged on the rear dial portion 511, and an anti-slip bump 5121 is convexly arranged on the front push portion 512 outwards.
When the reel 1 is locked, the backward shifting part 511 is shifted backwards, so that the dead locking hook 52 is abutted to the dead locking block 61 to promote the reel 1 to be locked, and the friction force is effectively increased by the plurality of anti-slip salient points 5111, thereby being beneficial to shifting operation.
When the reel 1 is opened, the front pushing part 512 is pushed forward, so that the dead locking hook 52 is separated from the dead locking block 61 to promote the reel 1 to keep a rotating state, and the anti-slip bump 5121 effectively increases friction force, which is beneficial to pushing operation.
Referring to fig. 3 and 4, a positioning block 44 is protruded from the end of the pressing member 4, and a positioning groove 513 matched with the positioning block 44 is formed in the end of the toggle block 51. After the wire wheel 1 is locked, the dead lock hook 52 is abutted to the dead lock block 61, and meanwhile, the positioning groove 513 on the toggle block 51 is fixed to the positioning block 44 on the pressing piece 4, so that the safety of the locked wire wheel 1 is enhanced, and the dead lock hook 52 is prevented from falling off from the dead lock block 61.
The utility model discloses a theory of operation does:
When the rotation of the reel 1 needs to be suspended: the user applies external force to the push button 5 and the pressing piece 4, the pressing piece 4 is abutted against the clamping piece 2, so that the clamping piece 2 rotates around the first cylindrical pin 7 clockwise, the elastic piece 3 is compressed, the lower part of the clamping piece 2 is inserted into the reel 1, and the clamping body 22 on the clamping piece 2 is clamped with the tooth 11 on the reel 1, so that the reel 1 is braked.
When the reel 1 needs to be locked: on the basis of finishing the pause step, the user exerts backward external force on the toggle block 51, and the backward toggle part 511 toggles backward, so that the dead locking hook 52 abuts against the dead locking block 61 to cause the reel 1 to be locked, and meanwhile, the positioning groove 513 on the toggle block 51 is fixed with the positioning block 44 on the pressing piece 4, so that the user does not need to continuously exert external force on the push button 5 and the pressing piece 4, and the normal work of the pet tractor can be ensured.
When the rotation of the reel 1 needs to be started: the user applies a forward external force to the toggle block 51, and pushes the forward pushing part 512 forward to separate the locking hook 52 from the locking block 61, so that the user does not apply any external force any more, the elastic piece 3 releases elastic potential energy, and then pushes the clamping piece 2, the pressing piece 4 and the push button 5, so that the lower part of the clamping piece 2 is far away from the reel 1, that is, the reel 1 keeps a rotating state.
the foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of the ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, its framework form can be nimble changeable, can derive series of products. But merely as a matter of simple deductions or substitutions, should be considered as belonging to the scope of patent protection of the present invention as determined by the claims submitted.
