Abstract

The invention discloses a high-strength antitheft coded lock which comprises a coded lock body, a key lock and a knob. The key lock comprises a key cylinder and a spring bolt plate which are arrangedon the knob and are used for locking or unlocking the rotating state of the knob. The coded lock comprises coded wheels and a tail end coded wheel, wherein grooves are formed between adjacent numbersof each coded wheel. A locking mechanism used for limiting rotation of the coded wheel is further arranged in a shell and comprises first inclined blocks, a limiting block and a supporting plate. Oneends of the first inclined blocks abut against the grooves, and the inclined faces of the other ends of the first inclined blocks are oppositely provided with second inclined blocks. Multiple first sliding blocks capable of moving in the perpendicular direction relative to the second inclined blocks are arranged in the second inclined blocks. The high-strength antitheft coded lock is simple in structure, and an ignorant outsider cannot open the lock even if the outsider knows the codes through the ingenious locking mechanism.

Description

technical field [0001] The invention relates to the technical field of mechanical combination locks, in particular to a high-strength anti-theft combination lock. Background technique [0002] The mechanical combination lock is a reliable all-mechanical combination lock with a large key volume without electronic devices; the mechanical combination lock usually used is a dial-type mechanical combination lock; it has the characteristics of not easy to crack, high security, small size and weight Lightweight, suitable for use in very important places such as vault doors, gun cabinets, safes, etc., but the digital combination of button-type mechanical combination locks currently on the market is single, easy to crack, and easy to be cracked by other people's locks, safe Sex is poor. Contents of the invention [0003] The main purpose of the present invention is to provide a high-strength anti-theft combination lock to solve the above-mentioned deficiencies in the prior art, wh...
