In this embodiment, by providing the protrusion structure 21 on the transmission member 20 and providing the first groove 31 on the rotation member 30, when the transmission member 20 rotates under the driving of the driving member 10, the protrusion structure 21 can extend into the first groove 31 and squeeze the side wall of the first groove 31, so as to drive the rotation member 30 to move together, when the rotation member 30 rotates in place, i.e. the locking member 40 moves to the locking position or the unlocking position, if the driving member 10 continues to rotate, the protrusion structure 21 can withdraw from the first groove 31, so that the protrusion structure is not contacted with the rotation member 30 any more, the normal rotation of the transmission member 20 is not affected by the rotation of the rotation member 30, so that the rotation of the driving member 10 has a certain redundancy, the blocking and the blocking of the driving member 10 are avoided, the normal operation of the driving member 10 is ensured, and meanwhile, the volume of the locking mechanism is reduced, and the protrusion structure 21 is convenient to apply to various locks.

In this embodiment, the driving member 10 is a motor, the driving member 20 is a driving wheel, the rotating member 30 is a sheave, the locking member 40 is a steel ball, the axis of the driving wheel intersects with and is perpendicular to the axis of the sheave, and the first groove 31 is disposed on the end face of the sheave and can penetrate the sheave.

As shown in fig. 1, the protruding structure 21 is a protruding column, the transmission member 20 and the rotation member 30 are wheel-shaped, the protruding column is obliquely arranged with the end surface of the transmission member 20, and the protruding column extends along the radial direction of the rotation member 30. Correspondingly, the first groove 31 is also formed along the radial direction of the grooved pulley, so that when the driving wheel rotates, the convex columns rotate together, extend into the first groove 31 along with the rotation of the driving wheel, squeeze the first groove 31 to enable the grooved pulley to rotate, and when the convex columns drive the grooved pulley to rotate by a certain angle, the convex columns rotate out of the first groove 31, so that the convex columns do not drive the grooved pulley to rotate any more, and a certain redundancy is provided for the rotation of the motor.

In this embodiment, the transmission member 20 further includes a limiting rod 22, the limiting rod 22 is disposed at the axial center of the transmission member 20 and located on the same end face as the protrusion structure 21, and the rotating member 30 has a second groove 32 for accommodating the limiting rod 22.

In particular, the axis of the transmission wheel passes through the sheave, that is to say at least a portion of the projection of the sheave onto the plane of the end face of the transmission wheel is located on the end face of the transmission wheel, ensuring that the stud can extend into the first recess 31. The cross section of the limit rod 22 is semicircular, so that a notch is formed in one side, facing the convex column, of the limit rod 22, and the notch enables the limit rod 22 to avoid the grooved pulley when the grooved pulley rotates. When the protruding column does not extend into the first groove 31, the limit rod 22 is located in the second groove 32 and stops the grooved pulley, so that the grooved pulley cannot rotate, locking of the grooved pulley is achieved, when the protruding column is about to extend into the first groove 31, the plane portion of the side wall of the limit rod 22 rotates to a position facing the grooved pulley, along with rotation of the protruding column, the limit rod 22 rotates together, the notch moves to a rotating path of the grooved pulley, and meanwhile in the rotating process of the grooved pulley, the grooved pulley passes through the notch, and rotation is achieved. The arrangement mode not only locks the grooved pulley when the grooved pulley does not need to rotate, but also provides avoidance for the movement of the grooved pulley when the convex column drives the grooved pulley, and ensures the normal operation of the locking mechanism.

With the forward rotation and the reverse rotation of the grooved pulley, the steel ball is switched back and forth between the locking position and the unlocking position, the forward rotation and the reverse rotation of the grooved pulley are realized by driving the convex column through the driving wheel, when the steel ball is switched to the locking position or the unlocking position, although the driving wheel can continue to rotate for a certain distance, when the distance is overlarge, the convex column can collide with the end face of the grooved pulley, in order to avoid the occurrence of the situation, two third grooves 33 are arranged, the two third grooves 33 are respectively positioned on the side edge of the second groove 32 far away from the first groove 31, and the first groove 31, the second groove 32 and the third groove 33 extend along the radial direction of the grooved pulley, so that the limiting position of the rotation of the convex column is limited.

In addition to the steel ball, the locking member 40 of the present embodiment may be an assembly having a spherical structure, and at least a portion of the spherical structure may extend into or retract from the recess 34. Such as a combination of balls and rectangular blocks, etc., wherein the ball portion mates with the sheave.

As shown in fig. 1 and 2, the locking mechanism further includes a stopper 50, and the stopper 50 is in clearance fit with the rotating member 30 to block the axial movement of the rotating member 30. The limiting block 50 is matched with the end face part of the grooved pulley, which is not provided with the first groove 31, the second groove 32 and the third groove 33, so as to avoid the convex column, and a tiny gap, preferably 0.07mm to 0.1mm, is reserved between the limiting block 50 and the end face of the grooved pulley, so that the limiting block 50 can limit the axial movement of the grooved pulley, and simultaneously, the friction between the limiting block 50 and the grooved pulley is reduced, and the grooved pulley is convenient to rotate.
