[0003] Therefore, a quick tightening strap structure of sports shoes in the prior art is disclosed, with publication number CN220571658U, comprising a connecting piece, the outer surface of the connecting piece is fixedly connected to a cylindrical wire-taking frame with a hollow interior, the front end of the wire-taking frame is laterally rotatably connected to a rotating column, a plurality of supporting rings are fixedly connected to the middle of the inner cavity of the wire-taking frame, a wire-taking rod is movably and laterally arranged inside the plurality of supporting rings, two wire-taking rollers are fixedly connected to the middle of the outer surface of the wire-taking rod, two wire-entry holes corresponding to the two wire-taking rollers are respectively provided on the outer surface of the wire-taking frame, two ends of the shoelace extend to the interior of the wire-taking frame through the two wire-entry holes and are respectively fixedly connected to the outer surfaces of the two wire-taking rollers.

[0004] The device tightens the shoelaces by rotating the take-up roller, but the shoelaces can only be wound around the take-up roller at a fixed position on the surface of the take-up roller. After being wound around the take-up roller for multiple turns, the shoelaces may pile up, and the piled and wound shoelaces may slip when a person moves, causing the shoelaces to loosen, resulting in a poor user experience when the device is actually used.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-4 As shown, an automatic tightening mechanism for sports shoes comprises a shell 1, a take-up rod 5 and a shoelace 2 which are arranged inside the shell 1 and pass through the side wall of the shell 1. Both ends of the partial take-up rod 5 located inside the shell 1 are sleeved with limiting rings 7 fixedly connected to the shell 1, and a fixing block 13 is fixedly connected at the center. The opposite surfaces of the two limiting rings 7 are rotatably connected to two reciprocating screws 6 rotatably connected to the shell 1, one end of one of the reciprocating screws 6 and a position on the surface of the take-up rod 5 are fixed with pulleys, and a belt strip 15 is sleeved between the two pulleys, a sliding block 14 slidably connected to the shell 1 is threadedly connected to the reciprocating screw 6, one end of the shoelace 2 is tied to the fixing block 13, and the other end is wound around the take-up rod 5 and passes through the sliding block 14 to extend to the outside of the shell 1, and a wire entry hole 12 for the shoelace 2 to pass through is opened on the side of the shell 1, and the end of one of the reciprocating screws 6 extends toward the other reciprocating screw 6 and is fixed to one end of the other reciprocating screw 6.

[0024] By adopting this technical solution, a reciprocating screw rod 6 is set up, so that the shoelaces 2 can be wound around different positions of the wire take-up rod 5 when being tightened by the wire take-up rod 5. The specific implementation method is that a person rotates the wire take-up rod 5, and the rotation of the wire take-up rod 5 drives the reciprocating screw rod 6 to rotate through the belt strip 15. The rotation of the reciprocating screw rod 6 drives the slider 14 to perform reciprocating linear motion on the reciprocating screw rod 6. When the slider 14 moves, it drives the shoelaces 2 received in the housing 1 to be wound around the wire take-up rod 5 at different positions of the wire take-up rod 5, thereby preventing the shoelaces 2 from accumulating and winding around the wire take-up rod 5.

[0025] like Figure 2 , Figure 3 and Figure 4As shown, a spring rod 10 is fixedly installed on the inner wall of the shell 1, the take-up rod 5 is hollow, and a fixed shaft 3 is slidably installed inside, both ends of the fixed shaft 3 extend from the inside of the take-up rod 5, and one end is located inside the shell 1 and fixedly connected to a limit plate 9, and the other end of the limit plate 9 is fixed to the telescopic end of the spring rod 10, and one end of the take-up rod 5 is also fixedly connected to a hollow plate 8, and a protrusion 16 is fixedly connected to one side of the limit plate 9, and the limit plate 9 is plugged into the hollow plate 8 through the protrusion 16 on its surface.

[0026] When the shoelace 2 is tightened, the limiting plate 9 and the hollow plate 8 are set to fix the wire-winding rod 5, so as to prevent the wire-winding rod 5 from rotating under the pulling of the tightened shoelace 2, causing the shoelace 2 to loosen. The specific implementation method is that, by pressing one end of the fixed shaft 3, the limiting plate 9 at the other end of the fixed shaft 3 moves, driving the protrusion 16 to move out of the hollow part of the hollow plate 8, and then rotating the wire-winding rod 5 to pull the shoelace 2 to be wound around the wire-winding rod 5. After tightening, the fixed shaft 3 is released, and the fixed shaft 3 moves under the push of the spring rod 10, and drives the limiting plate 9 to move toward the hollow plate 8. At this time, the wire-winding rod 5 is twisted to adjust the position of the hollow plate 8 so that the protrusion 16 is inserted into the hollow part of the hollow plate 8, so that the hollow plate 8 cannot rotate, thereby fixing the wire-winding rod 5.

[0027] like Figure 1 and Figure 2 As shown, the end surface of the partial take-up rod 5 located outside the housing 1 is fixedly connected with a twisting block 11 and a cover plate 4 rotatably installed to protect the other end of the fixed shaft 3, and the cover plate 4 and the twisting block 11 are fixed by magnetic attraction.

[0028] By adopting this technical solution, the fixed shaft 3 is protected by providing a cover plate 4 to prevent the fixed shaft 3 from being pressed in an accidental situation, resulting in the loss of fixation of the take-up rod 5. The twisting block 11 is provided to facilitate personnel to twist the take-up rod 5. In addition, the cover plate 4 and the twisting block 11 are fixed by magnetic attraction so that the cover plate 4 can always cover the end of the fixed shaft 3 when no one flips it, thereby achieving the effect of protecting the fixed shaft 3.

[0029] Working principle: When installing before use, open the shell 1, feed one end of the shoelace 2 into the shell 1 through the wire entry hole 12, and after passing through the sliding block 14 and the wire-taking rod 5, tie it to the fixed block 13. When in use, press the fixed shaft 3, rotate the wire-taking rod 5, pull the shoelace 2 and make it wind around the wire-taking rod 5. At this time, the reciprocating screw rod 6 is driven to rotate due to the rotation of the wire-taking rod 5, thereby driving the slider 14 to perform reciprocating linear motion, so that the shoelace 2 can be evenly wound around the wire-taking rod 5. After tightening the shoelace 2, loosen the fixed shaft 3, so that the limit plate 9 moves toward the hollow plate 8 under the push of the spring rod 10 and is plugged with the hollow plate 8 through the protrusion 16, thereby fixing the tightening rod 5.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
