Hidden lever drawing type locking connection structure for connection between plates

Abstract

The invention relates to a hidden lever drawing type locking connection structure for connection between plates. The hidden lever drawing type locking connection structure comprises an embedding body,a mounting fixing mechanism, a lock pin, a padlock block, a lever sliding block mechanism and a spiral drawing mechanism, wherein the mounting fixing mechanism is arranged on the embedding body; thelever sliding block mechanism comprises a fixed lever piece and a movable lever piece, the fixed lever piece is fixedly arranged in the embedded body, the movable lever piece is arranged in a lever cavity formed in the embedded body in a sliding mode, and an upper protruding part arranged on the movable lever piece and a lower protruding part arranged on the fixed lever piece can be stacked together; and the lock pin is connected with the movable lever piece, the padlock block is arranged on the lock pin, and the spiral drawing mechanism can enable the movable lever piece to drive the lock pinand the padlock block to make a padlock action. The scheme has the advantages of simple structure, easiness in implementation, convenience in assembly, firmness and tightness in connection, no gap atthe joint, capability of realizing repeated assembly and disassembly, no damage to the integrity and perfection of the plates or workpieces and the like.

Description

technical field [0001] The invention relates to the technical field of fittings for fixed connection between workpieces, in particular to a fast and reliable locking and connecting fitting mechanism that is very easy to use. Background technique [0002] In the assembly and fixed connection between the existing workpieces, the most commonly used method is to fix the connection with self-tapping screws. For example, in the assembly of all-aluminum furniture cabinets, when the aluminum alloy plates are fixedly connected with the aluminum alloy plates, an aluminum alloy square bar is usually fixed on the side of one of the aluminum alloy plates with self-tapping screws; There is a groove on the end surface of an aluminum alloy plate, which is nested on the aluminum alloy square bar, and then locked into the aluminum alloy square bar with self-tapping screws from the outside of the groove to realize the gap between the two aluminum alloy plates. vertical assembly connections. ...

AI Technical Summary

Problems solved by technology

In the practical application of this method, there are mainly some shortcomings: first, self-tapping screws are used for fixed connection, and the occlusal contact area between the self-tapping screws and the aluminum alloy material is small. When the connected aluminum alloy plate is subjected to Under the action of external force, the connection of self-tapping screws is prone to deformation and tearing, which affects the firmness and reliability of the assembly connection between aluminum alloy sheets; the second is to use self-tapping screws for fixed connection, usually one Self-tapping screws cannot be fixed, but several self-tapping screws are used for multi-point fixing, which usually leaves several screw heads on the surface of the aluminum alloy sheet, which affects the all-aluminum furniture cabinet. Third, self-tapping screws are used for fixed connection, because the same screw hole cannot be restored after being expanded once, and the same screw hole cannot be locked when it is used repeatedly, so that the all-aluminum furniture cabinet cannot be assembled and disassembled repeatedly. It greatly affects the moving of the all-aluminum furniture cabinet; Fourth, due to the lack of elastic squeeze or tension force, after assembly, there will be a large gap between the contact surfaces between the aluminum alloy sheet and the aluminum alloy sheet. Poor assembly tightness and poor assembly quality
