Detailed Description

The invention will be further described with reference to the embodiments shown in the drawings to which:

example 1

As shown in fig. 1 and 3, a key buckle used in cooperation with a key ring comprises a connecting band 1, wherein a sub-buckle 2 is fixedly connected to one end of the connecting band 1, a female buckle 3 is fixedly connected to the other end of the connecting band 1, and the sub-buckle 2 and the female buckle 3 are detachably and fixedly connected. The male button 2 and the female button 3 are positioned on the same side of the connecting belt 1. The sub-buckle 2 comprises a connecting column 21 fixed on the connecting belt 1, an elastic truncated cone-shaped fixture block 22 is fixedly connected to the end part of the connecting column 21 back to the connecting belt 1, and the side surface of the fixture block 22 protrudes relative to the side surface of the connecting column 21; female buckle 3 including fixing the connecting seat 33 on connecting band 1, connecting seat 33 back to the tip of connecting band 1 be equipped with spliced pole 21 complex connecting hole 31, connecting hole 31 towards the tip of connecting band 1 be equipped with fixture block 22 complex joint hole 32, spliced pole 21, connecting hole 31 are the round platform shape structure of mutually supporting. The design of the round platform shape has the guiding function, and a user can conveniently oppositely buckle the male buckle and the female buckle. The inner diameter of the end part of the connecting hole 31 facing the clamping hole 32 is smaller than the inner diameter of the end part of the clamping hole 32 facing the connecting hole 31, so that a step surface matched with the clamping block 22 is formed between the connecting hole 31 and the clamping hole 32. The latch 22 is caught in the catching hole 31 by this stepped surface. The clamping hole 32 penetrates through the connecting belt 1, and the clamping block 22 is prevented from being buckled into the clamping hole 32 to form negative pressure to influence subsequent detachment. The length of spliced pole 21 equals with the length of connecting hole 31, behind the joint hole 32 is gone into to fixture block 22 card, the connecting band of 2 ends of son knot is laminated with the connecting seat 33 of box 3, and the joint is more stable like this.
