[0015] Advantages of the present invention: In practical applications, the shoelace is wound around the pulley, and the shoelace passes through the belt holes; when it is necessary to loosen the shoelace, a downward pressing force is applied to the pressing member, so that the pressing member moves downward relative to the rotary cover. The multiple second rotating teeth of the downward-moving pressing member respectively abut and cooperate with the top inclined surfaces of the multiple rotary driving teeth of the rotary driving member. As the pressing member moves downward, the pressing member will abut the rotary driving member and move downward along the sliding hole. The multiple rotary driving teeth of the downward-moving rotary driving member respectively abut and cooperate with the bottom inclined surfaces of the multiple first rotating teeth of the pulley. As the pressing member and the rotary driving member are pressed downward, the elastic member is compressed, and the elastic member is in a state of storing elastic potential energy. And under the cooperation of the second rotating teeth, the rotary driving teeth and the first rotating teeth, the rotary driving member will drive the pulley to rotate in the reverse direction, and the pulley rotating in the reverse direction releases the shoelace wound thereon to realize the shoelace release, so as to facilitate the user to take off shoes; when the downward pressing force applied to the pressing member is released, the pressing member and the rotary driving member will reset under the resilience of the elastic member, so as to facilitate the next shoelace release operation; when it is necessary to tighten the shoelace, rotate the rotary cover in the forward direction.

The structure of the present invention is designed reasonably and ingeniously. By pressing the pressing member, the shoelace can be released, and by rotating the rotary cover, the shoelace can be tightened. The operation is simple and convenient, the stability of taking in and releasing the shoelace is good, it saves time and effort, and improves the efficiency of the user taking off and putting on shoes.

The rotary cover 2 is rotatably disposed on the base 1. The rotating wheel 4 is clamped in the rotary cover 2. The base 1 is provided with a rotation cavity 11, a belt passing hole 12 formed by opening on the side wall of the rotation cavity 11 and a ratchet 13 disposed at the open end of the rotation cavity 11. The pulley 3 is rotatably disposed in the rotation cavity 11. A plurality of first rotating teeth 31 are disposed in the inner cavity of the pulley 3. The rotating wheel 4 is located above the pulley 3. Pawls 41 are disposed on the circumference of the rotating wheel 4. The pawls 41 are engaged with the ratchet 13. A sliding hole 42 is formed in the middle of the rotating wheel 4. The rotation driving member 5 is slidably disposed in the sliding hole 42. A plurality of rotation driving teeth 51 are disposed on the circumference of the rotation driving member 5. The pressing member 7 is slidably connected to the rotary cover 2. The elastic member 6 is accommodated in the inner cavity of the pulley 3. The rotation driving member 5 is elastically connected to the base 1 via the elastic member 6. The top end of the elastic member 6 abuts against the bottom end of the rotation driving member 5. The bottom end of the elastic member 6 abuts against the bottom wall of the rotation cavity 11. The pressing member 7 is provided with a plurality of second rotating teeth 71. The plurality of rotation driving teeth 51, the plurality of first rotating teeth 31 and the plurality of second rotating teeth 71 are arranged in one-to-one correspondence. The bottom inclined surface 72 of the rotation driving tooth 51 is used to abut against the first rotating tooth 31. The top inclined surface 73 of the rotation driving tooth 51 is used to abut against the second rotating tooth 71. Specifically, the belt passing holes 12 are arranged in a circular array in the rotation cavity 11. The plurality of second rotating teeth 71 are arranged in a circular array around the central axis of the pressing member 7. The plurality of first rotating teeth 31 are arranged in a circular array around the central axis of the pulley 3. The plurality of rotation driving teeth 51 are arranged in a circular array around the central axis of the rotation driving member 5. The number of the belt passing holes 12 is two. The free ends of the two shoelaces on the pulley 3 respectively pass through the two belt passing holes 12. The number of the pawls 41 is three. The three pawls 41 are evenly distributed.

[0024] In practical applications, the shoelace is wound around the pulley 3 and passes through the belt hole 12; when it is necessary to loosen the shoelace, a downward pressing force is applied to the pressing member 7, so that the pressing member 7 moves downward relative to the rotary cap 2. The plurality of second rotating teeth 71 of the downward-moving pressing member 7 respectively abut and cooperate with the top inclined surfaces 73 of the plurality of rotary driving teeth 51 of the rotary driving member 5 one by one. As the pressing member 7 moves downward, the pressing member 7 will abut the rotary driving member 5 and move downward along the sliding hole 42. The plurality of rotary driving teeth 51 of the downward-moving rotary driving member 5 respectively abut and cooperate with the bottom inclined surfaces 72 of the plurality of first rotating teeth 31 of the pulley 3 one by one. As the pressing member 7 and the rotary driving member 5 are pressed downward, the elastic member 6 is compressed, and the elastic member 6 is in a state of storing elastic potential energy. And under the cooperation of the second rotating teeth 71, the rotary driving teeth 51 and the first rotating teeth 31, the rotary driving member 5 will drive the pulley 3 to rotate reversely, and the reversely rotating pulley 3 releases the shoelace wound thereon to realize the release of the shoelace, so as to facilitate the user to take off the shoes; when the downward pressing force applied to the pressing member 7 is released, the pressing member 7 and the rotary driving member 5 will reset under the restoring force of the elastic member 6, so as to facilitate the next release operation; when it is necessary to tighten the shoelace, the rotary cap 2 is rotated forward, and the forward-rotating rotary cap 2 drives the rotary wheel 4 to rotate forward. The forward-rotating rotary wheel 4 drives the rotary driving member 5 to rotate synchronously. The forward-rotating rotary driving member 5 abuts the side wall of the first rotating tooth 31 of the pulley 3 through the side wall of the rotary driving tooth 51, so that the pulley 3 follows the rotary driving member 5 and rotates forward synchronously. The forward-rotating pulley 3 winds the shoelace to realize the retraction of the shoelace, so that the shoelace is tightened, so as to facilitate the user to wear the shoes firmly; since the pawl 41 on the rotary wheel 4 is engaged with the ratchet 13 on the base 1, the rotary wheel 4 can only rotate forward, avoiding the unintentional loosening of the shoelace caused by the reverse rotation of the rotary wheel 4, and improving the stability of tightening the shoelace. The structural design of the present invention is reasonable and ingenious.
