Fast locking and connecting device

Abstract

The invention relates to locking and connecting hardware fittings, in particular to a fast locking and connecting device. The fast locking and connecting device comprises a telescopic rod fixing block which is fixed on a first fixed surface, and a tensioning block which is fixed on a second fixed surface. A through hole is formed in the telescopic rod fixing block, and a telescopic rod which can stretch and retract in the through hole is arranged in the through hole. The top of the telescopic rod is provided with a driving mechanism which controls the telescopic rod to conduct stretching and retracting actions. The bottom of the telescopic rod is in a flat structure which is symmetric about a central axis. The tensioning block is provided with a locking hole, and the shape of the locking hole is matched with the bottom outline of the telescopic rod. The driving mechanism drives the telescopic rod to extend downwardly and outwardly. After the flat structure of the bottom of the telescopic rod passes through the locking hole, the driving mechanism is rotated to drive the telescopic rod to rotate, and locking between the telescopic rod and the locking hole is realized through the difference of the transverse length and the longitudinal length of the flat structure. By means of the fast locking and connecting device, the whole operation process is simple, a special tool is not needed, and the operation can be realized with hands.

Description

technical field [0001] The invention relates to locking and connecting hardware fittings, in particular to a fast locking and connecting device. technical background [0002] In daily life and industrial production, it is often necessary to splice some boxes, frames and other objects. The existing general splicing method is to cooperate with the screw and the nut. First, the screw passes through the two objects to be spliced. Then lock it with a nut. This type of locking connection structure is very inconvenient during installation, requiring a large number of installation and locking operations of screws and nuts, and the workload is very large, and when some boxes or frames need to be replaced, repaired and other maintenance operations At the same time, it is necessary to dismantle the relevant screws and nuts and then install them, and for the different specifications of the screws and nuts, it is necessary to use special tools that do not pass the specifications to real...

Problems solved by technology

This type of locking connection structure is very inconvenient during installation, requiring a large number of installation and locking operations of screws and nuts, and the workload is very large, and when some boxes or frames need to be replaced, repaired and other maintenance operations At the same time, it is necessary to dismantle the relevant screws and nuts and then install them, and for the different specifications of the screws and nuts, it is necessary to use special tools that do not pass the specifications to realize the operation, so this type of locking connection structure no matter A large number of locking and unlocking operations are required in the early installation and later maintenance processes, the workload is heavy, the operation is complicated, and the efficiency of the entire working process is low
