AI Technical Summary

Technical Problem

Existing shoe buckle structures are prone to slipping when tightening shoelaces, resulting in ineffective locking. They are also mainly suitable for children's shoes and cannot meet the needs of sports shoes and other scenarios where higher locking reliability is required.

Method used

A stabilizing locking buckle was designed, which uses a combination structure of three winding holes through the reel, a double elastic element positioning center shaft, a positioning rack ring and elastic strip anti-reverse teeth, and a positioning ring groove and positioning ring to increase the contact area and friction between the shoelace and the reel, ensuring stability, and enabling convenient operation through the buckle and convex ring structure.

Benefits of technology

It improves locking stability, expands the applicable scenarios to sports shoes, reduces the risk of shoelaces slipping and loosening, balances ease of operation and flexibility of use, and extends the service life of shoelaces.

Abstract

The utility model discloses a stable rotation lock catch device, which comprises a fixed base, a mounting seat is fixedly clamped at the top of the fixed base, an I-shaped take-up device is arranged in the mounting seat in a limiting manner, a positioning piece capable of driving the take-up device to rotate is arranged at the top of the mounting seat, and a rotary upper cover is fixedly clamped at the top of the positioning piece. A limiting placing groove for placing the take-up device is formed in the mounting seat, and a take-up space is formed between the middle part of the take-up device and the inner wall of the limiting placing groove; compared with the prior art, the shoelace take-up device has the advantages that the locking stability is improved, the adaptive scene is widened, the contact area and friction force between a shoelace and the take-up device are increased by arranging the three winding through holes penetrating through the take-up device in the winding hole in cooperation with a shoelace cross threading mode, and the slipping and loosening risks of the shoelace are effectively reduced; stability and operation convenience are both considered; rotation prevention is combined with flexible transmission; assembly and maintenance are convenient, and the shoelace is protected.
