Problems solved by technology

This kind of expansion buckle can be reused 3-4 times, but the mold is relatively complicated, and the manufacturing cost is relatively high; and this kind of expansion buckle needs to be assembled and disassembled by cross lifting, which takes a long time to disassemble
[0004] 2. Non-detachable expansion buckle
[0005] Therefore, the existing two kinds of expansion buckles cannot be reused for a long time, and the installation and disassembly are extremely inconvenient, and the required working time is relatively long

Abstract

The invention relates to an actuating travel self-unlocking type expansion buckle consisting of an auxiliary buckle and a master buckle, wherein the head part of the master buckle is provided with a cap which is provided with a hole in the middle, and the tail part of the master buckle is provided with a blocking end; a limiting table is arranged in the part of the blocking end, close to the cap, while the other end of the master buckle is provided with a blocking reverse buckle; the auxiliary buckle is of a nail-type structure and is provided with a first travel slot and a master buckle yielding unlocking slot; and the outer surface of the auxiliary buckle is provided with a master buckle locking and blocking groove. The expansion buckle is configured into a two-actuating-travel limiting structure, and meanwhile, the master buckle yielding unlocking slot is arranged in the auxiliary buckle in a second actuating travel, so that the functions of expanding and locking the auxiliary buckle in the first actuating travel and self-locking the auxiliary buckle by the master buckle in the second actuating travel are achieved.

Description

technical field [0001] The invention belongs to the technical field of buckle and buckle connection structures, and in particular relates to a push-range self-unlocking expansion buckle structure. Background technique [0002] There are two types of expansion buckle structures commonly used at present: [0003] 1. Thread fit expansion buckle. The outer surface of the sub-button and the inner surface of the female buckle of this kind of expansion buckle are designed as matching threads, and the head of the sub-button is designed with a cross groove. This kind of expansion buckle can be reused 3-4 times, but the mold is relatively complicated, and the manufacturing cost is relatively high; and this kind of expansion buckle needs to be assembled and disassembled by cross lifting, and the disassembly time is long. [0004] 2. Non-detachable expansion buckle. The surface of the sub-button and the female buckle of this kind of expansion buckle is smooth, and the space between t...
