AI Technical Summary

Technical Problem

The decorative cover of the existing lacing device is difficult to replace, the magnetic connection is easy to fall off, and the buckle connection requires tools and is easily damaged, which cannot meet the need for convenient replacement.

Method used

Design a screw cap structure that facilitates the replacement of the outer shell. The inner screw cap and the outer shell are linked together by a locking block and a splitting structure. The outer shell can be rotated to the separation groove to separate without tools. The assembly guide and the guided part are combined to achieve non-precise alignment and locking.

Benefits of technology

It enables convenient assembly and disassembly of the outer shell and inner screw cap, simplifies the replacement process, improves assembly accuracy and convenience, and is suitable for fastening items such as shoes, clothing, hats and bags.

Abstract

Disclosed in the present invention are a turn buckle structure facilitating face shell replacement and a lacing device comprising same. The turn buckle structure facilitating face shell replacement comprises an inner turn buckle and a face shell; the face shell is detachably mounted and arranged on the outer side of the inner turn buckle, and the face shell is provided with a fastening block; the inner turn buckle is provided with a separating-fastening structure, the fastening block being fitted to the separating-fastening structure to realize the fastening and separation between the inner turn buckle and the face shell. The separating-fastening structure comprises a snap-fit portion and a separation recess, and the fastening block and the snap-fit portion are in a snap-fit connection, such that the face shell and the inner turn buckle are in a linkable connection. The face shell can also rotate relative to the inner turn buckle to rotate the fastening block to the separation recess, and separate the face shell from the inner turn buckle by means of the separation recess, thereby meeting the requirement of a user for quickly replacing the face shell.
