Coupled mechanical password anti-theft lock

Abstract

The invention provides a coupling type mechanical code anti-theft lock which comprises a lock seat board, a main lock rod and an auxiliary lock rod. The coupling type mechanical code anti-theft lock is characterized in that a shield is arranged on the lock seat board, a pin rod fixing pipe is arranged in the middle of the lock seat board, code rotary disc assemblies are sequentially arranged on the pin rod fixing pipe and divided into inner rotary wheels and an outer rotary wheel through the lock seat board, the inner rotary wheels comprise odd wheels and even wheels, the odd wheels and the even wheels are combined in a sleeved mode through a connecting pipe and connected with the outer rotary wheel in the shield, the rotary wheels are separated through thin planet boards, the outer rotary wheel and the connecting pipe are connected with an outer connecting wheel in an interference fit mode, and the outer rotary wheel is provided with volute spiral springs and limiting nails, wherein the volute spiral springs and the limiting nails are arranged for limiting. The inner rotary wheels are provided with reset springs and pins for localization. Each wheel is provided with ten wire holes connected with an alarm device. The odd wheels and the even wheels are respectively provided with one code ball hole which corresponds to a code rod assembly. An annular groove is formed in the side face of the last odd wheel. The bottom of the groove is provided with an undulating cushion block and a mobile phone is clicked through a trigger device in the process of rotation. A blocking piece controlled by codes, an anti-buckling device internally provided with a trigger and a main operating lock rod and an auxiliary lock rod are arranged below the lock seat board. The defect that a mechanical lock key hole in the prior art is easily intruded by a stolen matched key, a universal key and impurities and foreign things blocking the key hole is overcome and safety of the lock is improved.

Description

technical field [0001] The patent of the present invention relates to a lock, in particular to a coupled mechanical password anti-theft lock. Background technique [0002] Locks are an indispensable product in people's lives. It has been widely used in all households and facilities that need protection. In people's lives, locks are one of the products that are important for the protection of important properties. They are important in promoting social security. It has played a great role in promoting stability, economic prosperity, and protecting the interests and safety of the people. [0003] In recent years, due to the weak anti-theft of ordinary locks, the theft rate has remained high, and thefts have occurred frequently due to damage to home locks.

[0003] In recent years, due to the shortcomings of ordinary locks that are not effective in preventing theft, the theft rate has remained high, and home locks have been damaged and theft cases have occurred frequently

From the analysis of the lock market currently in use, ordinary mechanical locks occupy most of the market share, and the existing various mechanical locks are similar in structure and function, especially the universal keyhole locks have a single function. The simple structure leaves a great potential safety hazard, allowing some people with bad intentions to block foreign objects into the keyhole, and criminals can use the master key to directly crack the lock. How can it be safe?
