Connecting structure capable of being rapidly mounted and dismounted

Abstract

The invention relates to a connecting structure capable of being rapidly mounted and dismounted. The connecting structure comprises a locking pin and a locking block. The locking pin comprises a pin shaft and a pin shaft sleeve arranged on the lower portion of the pin shaft in a sleeving mode through threads. The bottom surface of the pin shaft is a conical surface. The lower portion, under the pin shaft, of the pin shaft sleeve is provided with a plurality of through holes evenly distributed around the axis, and a steel ball which can freely move but can not fall out is arranged in each through hole. The locking block is provided with a connecting hole and a containing cavity, the connecting hole is formed in the top surface of the locking block, and the bottom of the connecting hole is communicated with the top of the containing cavity, and the top surface of the containing cavity is a conical surface. In the installation process, the pin shaft sleeve and the locking block are fixed to a connector and a connected part respectively, the pin shaft sleeve penetrates through the connector and enters the containing cavity of the locking block through the connecting hole, the pin shaft is rotated downwards so that the steel balls can be pushed to squeeze the conical top surface of the containing cavity through the conical bottom surface of the pin shaft, and the connector and the connected part squeeze and fix each other when subjected to force in opposite directions. In the dismounting process, the pin shaft is rotated upwards, the steel balls are not subjected to force, and then the connector and the connected part are separated.

Description

technical field [0001] The invention relates to a connection mechanism, in particular to a connection mechanism that can be quickly installed and disassembled. Background technique [0002] When the connecting piece and the connected piece need to be frequently installed and disassembled, it is generally necessary to connect through a detachable connecting piece. The traditional detachable connection mainly uses bolts and threaded holes to fix the connecting part and the connected part. The installation process of this traditional threaded connection is slow (the bolt needs to be screwed into the entire thread), and a wrench, screwdriver, etc. are required for disassembly. Tools, installation and disassembly are time-consuming and laborious, and a certain operating space must be reserved for the wrench, which cannot be adapted to a narrow space. Contents of the invention [0003] The purpose of the present invention is to provide a connecting mechanism that can be quickly...
