Abstract

A mechanical coded lock not allowing code testing comprises a fixing base, a driving plate, a first driven plate, a second driven plate, a positioning frame, a plug board base, a supporting block and a magnetic block and is characterized in that a rotary plate is arranged under the fixing base and connected with a rotary shaft; the rotary shaft penetrates through the fixing base and connects the first driven plate, the second driven plate and the positioning frame together; the driving plate and the rotary shaft are fixed together through a metal pin; first grooves and a driving plate insertion grooves are formed in the edge of the driving plate; first driven plate grooves and a first driven plate insertion groove are formed in the edge of the first driven plate; second driven plate grooves and a second driven plate insertion groove are formed in the edge of the second driven plate; the positioning frame is provided with T-shaped grooves, positioning blocks and a protrusion block; and a positioning shaft is arranged on the protrusion block. The secrecy performance of the mechanical rotary plate coded lock can be greatly improved.

Description

technical field [0001] The invention relates to locks, in particular to a mechanical combination lock which cannot be tested for combination. Background technique [0002] Today, the turntable mechanical combination lock is widely used in safes, file cabinets, security doors, warehouse doors and mechanical blocking mechanisms. The advantage of this combination lock is that it does not need a key, does not need a power supply, does not need a battery, and is easy to operate; because it is a fully mechanical structure and simple in structure, it can withstand quite harsh external environments, is strong and reliable, and has a wide range of applications. However, the turntable type mechanical combination lock is more likely to be tested by an experienced illegal unlocker to test out the password data, so there is a serious potential safety hazard. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a mechanical comb...
