a mechanical lock

Abstract

The invention provides a mechanical lock. The mechanical lock effectively solves the problem that the safety of an existing mechanical lock is prone to being cracked. According to the achieved technical scheme, the mechanical lock comprises a control box; a first disc is arranged in the control box and provided with a second disc, and a clamping plate is formed and provided with a notch; the control box is provided with a first shaft, the first shaft is provided with a sleeve, an annular plate is arranged on the right side of the first disc and provided with a second shaft, the annular plate is provided with a first blind hole, and the first blind hole is provided with a disc-shaped cam; a through hole is formed in the bottom of the first blind hole and internally provided with a pin; thepin is provided with a reset spring, and the second shaft is provided with a clamping hole; the annular plate is provided with an annular ring, the annular ring is provided with a first arc groove, afirst sliding block is arranged in the first arc groove and fixed to the annular plate, and a clamping mechanism is arranged on a right side plate of the control box; and the mechanical lock is ingenious in structure, the defect that the existing mechanical lock is prone to being cracked is effectively overcome, the security of the mechanical lock is greatly improved, and the possibility of important object losing is reduced.

Description

Technical field [0001] The invention relates to the technical field of security machinery, in particular to a mechanical lock. Background technique [0002] At present, the marble and blade lock cylinders on the market usually require a key to be inserted into the lock hole, and the lock can be opened when the key is turned under normal conditions. The lock cylinder of this kind of lock is provided with a rotatable keyhole shaft and a non-rotatable lock cylinder seat. One or more rows of marbles are arranged on one side of the keyhole. There is a lock column behind the pin, and a spring is behind the lock column. In the locked state, the lock cylinder is clamped between the lock cylinder seat and the lock hole shaft under the elastic force of the spring. When the key is inserted into the keyhole, the concave and convex part of the key presses the pin, the pin pushes the lock cylinder, the lock cylinder presses the spring and completely retracts into the lock cylinder seat, at th...
