Pushing disconnection type mechanical coded lock

Abstract

The invention provides a pushing disconnection type mechanical coded lock and relates to the field of rotating disc number-checking type mechanical coded locks. Six knob discs are directly rotated tocomplete number-checking operation. A handle drives a cam mechanism to rotate to achieve unlocking and locking. In the number-checking process, after a linkage shaft movably connected with all knob shafts penetrates through a lock body, an overload protection device and a code changing device are driven to rotate, then the linkage shaft coaxially returns into the lock body, a sawtooth wheel and apulling wheel are driven to rotate, and finally, six following wheels provided with notches follow to rotate. In the unlocking process, a cam firstly pushes a locking plate to be inserted into a toothgroove of the sawtooth gear, all the knob discs cannot rotate, then a pushing plate enables a transverse sliding plate and the following wheels to move transversely, the following wheels break away from contact with an ejection pin on the pulling wheel, finally, an inserting plate is pushed to be inserted into the notches of all the following wheels, the cam continues rotating for achieving unlocking, and the lock cannot be unlocked technically. When the handle or the knob discs are turned around with brute force, the handle or the knob discs can idle, and code changing operation and code confusing operation can be carried out easily.

Description

technical field [0001] The invention relates to the field of turntable-marked mechanical coded locks, in particular to a push-and-release mechanical coded lock. Background technique [0002] The turntable matching mechanical code lock has a wide range of applications. As a mechanical blocking mechanism, it is often used on file cabinets, vaults, safes, safes, and security doors. However, there have been a series of problems for a long time. First, the registration process takes too long 1. The operation is inconvenient; second, the password cannot be changed, which is very inconvenient for hiding and storing the password or remembering the password; third, the anti-theft opening performance cannot be opened technically, because the knob plate is in direct contact with the blocking mechanism inside the lock through the knob shaft. It is easy to crack by hearing, feeling and experience; fourth, the anti-destructive performance is not good enough, especially the combination loc...

Problems solved by technology

[0005] However, there are certain problems with the "hole-sealed mechanical combination lock", mainly because the registration operation process is relatively complicated: when registering, you need to press each knob first, and insert the convex edge of the knob shaft into the docking groove of the turntable shaft In order to complete the check number operation; after unlocking and locking, in order to prevent the password from being stolen, it is necessary to confuse the numbers corresponding to the sights on each knob plate, that is, the garbled code operation process also needs to be completed by pressing the knob plate first and inserting the convex edge into the docking groove. , causing some trouble to users
