A dust-proof mechanical lock

Abstract

The invention discloses a dust-proof mechanical lock, which comprises a device box body. A lock cylinder cavity is arranged in the device box body, and a lock cylinder device is arranged in the lock cylinder cavity, as the dust-proof and anti-theft protection of the first protection. The existence of the plate increases the time for the lock to be cracked, effectively prevents the exposure of the lock hole, and makes it impossible for thieves who do not carry suitable tools to open it. The cylindrical lock cylinder cavity and lock sleeve and the pin mechanism distributed at 360 degrees It makes it difficult to operate the opening method of the traditional pinch-type technology, and the part of the alarm pin of the alarm device exposed in the lock cylinder cavity is exactly the same as other pins outside the lock cylinder. When the thief moves the alarm pin inside, the alarm activation module will alarm Pushed by the rotating spring of the module, the module passes through the alarm activation chamber and touches the alarm activation button to activate the alarm system, thereby playing a good role in anti-theft. At the same time, it prevents dust from directly entering the lock cylinder cavity and affecting the unlocking effect.

Description

technical field [0001] The invention relates to the technical field of a dust-proof mechanical lock, in particular to a dust-proof mechanical lock. Background technique [0002] At present, locks refer to utensils that play a sealing role. It includes locks, keys and accessories. It is generally interpreted as "a seal that must be opened with a key." Locks are not only protective products, but also have the functions of "management" and "decoration". With the development of modern locks, people have thoroughly studied the structure and mechanism of locks. In the face of habitual thieves , Two steel wires or a few simple tools can quickly open these locks. Therefore, methods and tools for unlocking without keys are emerging in an endless stream, and the traditional keyholes are prone to dust, which affects the smoothness of unlocking. , need a kind of dust-proof mechanical lock that can effectively prevent technology from opening.
