Embodiment Construction

[0091] The following will be described in conjunction with the accompanying drawings and a specific embodiment.

[0092] see Figure 1 to Figure 27 . A kind of mechanical lock described in this embodiment includes two inner and outer base plates 100 for installing various components. The two base plates 100 are two mutually parallel plates of the mechanical lock housing. Different positions for small range of fine-tuning. The base plate 100 is provided with a handle shaft hole 101, a clutch pressing block assembly groove 102, a seesaw shaft 103, a rotating fork shaft 104, a total transmission block assembly groove 105, a limit post 106, a first lock tongue assembly groove 107, and a first safety bolt The shaft 108, the inner lock bolt assembly hole 109, the second spring fixing column 110, the fifth spring fixing column 111, and a key socket are also arranged on the outdoor base plate. The handle shaft hole 101 is used for installing the handle shaft. The handle includes an...

Abstract

The invention discloses a mechanical lock. The mechanical lock comprises an inner base plate and an outer base plate, wherein the inner base plate and the outer base plate are used for installation of various parts, and the parts include a main transmission block used for controlling a locking dog to stretch or contract, a warped plate used for controlling the main transmission block to move up and down, a clutch device used for controlling the warped plate to rotate, a lock hook used for controlling the clutch device to move up and down, and a lock cylinder used for controlling the rotating angle of the clutch device. According to the mechanical lock, the technical defects caused by the structure, in the prior art, that a lock cylinder is exposed out of a lock and a user needs to insert a key into the lock cylinder and rotate the key to achieve unlocking are overcome, and the safety performance of the lock is greatly improved; the problems that the existing lock cylinder can be unlocked and damaged easily, the safety performance is poor due to the high mutual-unlocking rate, the design structure is complicated, and the cost is high are solved.

Description

technical field [0001] The invention relates to a lock. Background technique [0002] Now the marbles and blade lock cylinders that are available on the market usually need to insert a key in the lockhole, and the lock can be opened when the key is turned under normal conditions. The lock core of this lock is provided with a rotatable lock hole shaft and a non-rotatable lock core seat. One side of the lock hole is provided with one or more rows of marbles. In the locked state, the lock column is stuck between the lock core seat and the lock hole shaft under the elastic force of the spring. When the key is inserted into the lock hole, the concave and convex parts on the key press the pin, and the pin pushes the lock cylinder, and the lock cylinder presses the spring and completely retreats into the lock cylinder seat. At this time, the lock shaft can rotate with the key, and the lock shaft rotates to drive the setting A cam at the end or in the middle of the shaft, the cam ...
