Abstract

A machine combination lock with a password incapable of being tested comprises a fixing base, a drive disc, a first driven disc, a second driven disc, a positioning rack, an insert board base, supporting blocks and magnet blocks, and is characterized in that a rotary disc is arranged under the fixing base and connected with a rotary shaft; the rotary shaft penetrates through the fixing base to string the first driven disc, the second driven disc and the positioning rack together; a metal pin is used for fixing the drive disc to the rotary shaft; first grooves are formed in the edge of the drive disc, and a drive disc insert groove is formed in the drive disc; first driven disc grooves are formed in the edge of the first driven disc, and a first driven disc insert groove is formed in the first driven disc; second driven disc grooves are formed in the edge of the second driven disc, and a second driven disc insert groove is formed in the second driven disc insert groove; and a T-shaped groove is formed in the positioning rack, positioning blocks and protruding blocks are arranged on the positioning rack, and a positioning shaft is arranged on the protruding blocks. By adoption of the machine combination lock with the password incapable of being tested, the secrecy performance of the mechanical rotary disc combination 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...
