Rapid locking and unlocking device

Abstract

The invention relates to a rapid locking and unlocking device. The rapid locking and unlocking device comprises a fixed rod, a plurality of moving parts and spring assemblies; the moving parts can move in the length direction of the fixed rod; the fixed rod is provided with a plurality of limiting grooves; the moving parts are provided with through holes, and the through holes can cover the limiting grooves; the spring assemblies are positioned in the limiting grooves; when the moving parts move along the fixed rod and pass through the spring assemblies, positioning modules of the spring assemblies extend out of the through holes and lock the moving parts; when the moving parts are locked, the moving parts can move along the fixed rod under the action of external force to press the spring assembly positioning modules into the limiting grooves, and unlocking is achieved. A sleeve is quickly locked through locking stop pins of the spring assemblies, connecting parts such as screws are not needed, and operation is convenient and fast. Unlocking of the sleeve and replacement of the position of the sleeve can be rapidly achieved by applying external force to pull the sleeve upwards, connecting parts such as screws do not need to be disassembled, and the sleeve is rapidly moved to replace the position.

Description

technical field [0001] The invention relates to the technical field of connection components, in particular to a quick locking and quick unlocking device. Background technique [0002] In daily life, the fixing between two parts usually uses screws or bolts to achieve locking. If screw locking is used, it is necessary to use a screwdriver and other tools to tighten the screws when fixing, and use a screwdriver and other tools to remove the screws when disassembling. [0003] However, for those connection occasions that do not have strict requirements on the locking force and need to be frequently disassembled and replaced, screw connections are used, which greatly reduces the working efficiency of the connecting parts when changing the working position. [0004] How to provide a brand-new connection structure, which is applied to connection occasions where the location is often disassembled and replaced, is a technical problem to be solved urgently in this field.
