Quick disassembly and assembly connecting structure of plastic part

Abstract

The invention discloses a quick dismounting and connecting structure for a plastic part, and belongs to the technical field of quick connecting parts. The device mainly comprises an insertion piece and a clamping piece capable of being clamped with or separated from the insertion piece, the insertion piece comprises a body, an insertion sleeve located at the front end of the body, two positioning piles clamped between the body and the insertion sleeve and a supporting block located between the two positioning piles, and an insertion block is arranged at the front end of the body; a supporting groove used for storing the supporting block is formed in the front end of the inserting block, two positioning arms are arranged on the two sides of the supporting groove respectively, the positioning piles are arranged between the two positioning arms on one side in a sliding mode respectively, and fixing arms used for clamping the inserting block are arranged on the two sides of one end of the inserting sleeve respectively. The inner walls of the opposite sides of the two fixing arms correspond to the two side walls, not provided with the positioning arms, of the inserting block. According to the connecting structure, a connecting rod can be omitted when the plastic parts are hinged.

Description

technical field [0001] The invention relates to the technical field of plastic products, in particular to a quick disassembly and assembly connection structure for plastic parts. Background technique [0002] The commonly used articulating method of quick connectors for plastic parts is to insert the connecting block of one plastic connecting part into the connecting groove of another plastic connecting part, then use a connecting rod to pass through the connecting block and the inner wall of the connecting groove, and connect the connecting rod to the connecting groove. Blocks or connecting grooves are fixed to complete the hinge. [0003] Since one of the plastic connectors needs to be fixedly connected with the connecting rod, interference fit is usually used. If the plastic part is not elastic enough, after the connecting rod is inserted, the connection of the plastic part is easy to crack. If the plastic part has sufficient elasticity, during use, The torque during the...

AI Technical Summary

Problems solved by technology

[0003] Since one of the plastic connecting parts needs to be fixedly connected with the connecting rod, an interference fit is usually used. If the plastic part is not elastic enough, the joint of the plastic part is easy to crack after the connecting rod is inserted. If the plastic part is sufficiently elastic, during use, The torque during the rotation between the connecting parts will easily drive the connecting rod to rotate. Due to the soft material of the plastic parts, it is easy to wear and tear with the connecting rod. Long-term use will easily cause the connecting rod to loosen and eventually fall off.
