Self-locking buckle

Abstract

The invention discloses a self-locking buckle, and relates to the technical field of building decoration. The self-locking buckle is used for directly or indirectly connecting a first target object and a second target object; a first fixed piece is directly or indirectly connected with the first target object; the first fixed piece is provided with an elastic clamping groove; at least two groups of penetrating horizontal clamping teeth are arranged on the outer side of the elastic clamping groove; multiple rows of chutes are arranged on the inner-side horizontal clamping teeth of the elastic clamping groove; a second fixed piece is directly or indirectly connected with the second target object; and a bulge matched with the first fixed piece is arranged on the second fixed piece. The self-locking buckle provided by the invention has the beneficial effects that the screwing occlusion of a bolt and a nut is changed into linear occlusion, and the progressive locking from shallow to deep can be realized just like threaded connection. Due to linear occlusion, the occlusion area is large, the occlusion force is high, the self-locking buckle is suitable for all long and narrow spaces, in addition, one material with favorable elasticity can be directly connected with workpieces made of different materials, and the self-locking buckle is free of punching, does not damage the material stress, and does not occupy space.

Description

technical field [0001] The invention relates to the technical field of building decoration, in particular to a self-locking buckle. Background technique [0002] The most common hardware connection is a variety of threaded connections (including screw and bolt connections with the same principle as threaded connections) and buckle connections based on the snap button principle (including round buckles and strip buckles). Each connection method has advantages. The threaded connection can be gradually locked by thread rotation, thereby gradually increasing the connection force. But all kinds of threaded connections need screw rods and nuts, and there must be enough space to rotate the nuts, and real fast assembly cannot be realized. Although various snap connections do not require space for rotating the nut, they can also be quickly installed, but they do not have the force progressive function of thread tightening, and most of them only have the connection function, no lock...

Problems solved by technology

However, all kinds of threaded connections require screws and nuts, and there must be enough space to rotate the nuts, and it is impossible to achieve real quick assembly

Although various snap connections do not require space for rotating the nut, they can also be quickly installed, but they do not have the force progressive function of thread tightening, and most of them only have the connection function, no locking function, and the connection force is constant. and limited
