Variable-pitch locking dog of mechanical digital lock

Abstract

The invention relates to a mechanism digital lock. A variable-pitch locking dog of a mechanical digital lock consists of a main locking dog and an auxiliary locking dog, wherein the main locking dog is a lock clamping end, the main locking dog and the auxiliary locking dog are connected in a sliding way by a sliding rail and a track slot, the lock clamping end is provided with a return spring hole parallel to the sliding rail, two side surfaces of the return spring hole are provided with lock clamping plate driving pins, the auxiliary locking dog is provided with a spring stabilizing penetrating pin corresponding to the return spring hole of the main locking dog, a spring is arranged on the spring stabilizing penetrating pin and is assembled with the return spring hole, and the main locking dog and the auxiliary locking dog are provided with relative travel limiting devices. The variable-pitch locking dog has a simple structure, and adopts a two-body structure; the main locking dog and the auxiliary locking dog are sheathed together coaxially in a sliding way, and can slide relatively to realize a variable-pitch integral structure; and variable-pitch control on the main locking dog and the auxiliary locking dog can be conducted freely by a handle indoors and outdoors, therefore, the mechanical digital lock can be freely controlled to be opened and closed from the inner side and the outer side, and can be used on a door body such as an antitheft door and the like.

Description

technical field [0001] The invention relates to a mechanical digital lock, in particular to an accessory lock bolt thereof. Background technique [0002] The vast majority of traditional vault doors and anti-theft doors use pin cylinders and electronic anti-theft locks. Among them, the pin locks are not only low in density, but also very simple and easy to open and destructively open; It is easy to open, but it is unlocked by sending electricity to the electromagnet. This is also its most fatal flaw. Not only is the screen damaged too easily, but the consequences are more serious if you use a decoder. In summary, the current combination locks for anti-theft doors There are safety hazards. [0003] At present, mechanical digital locks are widely used in various safes. Since the safe only needs to be opened outside, the mechanical digital locks cannot be controlled freely inside and outside the door at the same time. The main reason is that the mechanical digital locks The d...

[0002] The vast majority of traditional vault doors and anti-theft doors use pin cylinders and electronic anti-theft locks. Among them, the pin locks are not only low in density, but also very simple and easy to open and destructively open; It is easy to open, but it is unlocked by sending electricity to the electromagnet. This is also its most fatal flaw. Not only is the screen damaged too easily, but the consequences are more serious if you use a decoder. In summary, the current combination locks for anti-theft doors There are safety hazards

[0003] At present, mechanical digital locks are widely used in various safes. Since the safe only needs to be opened outside, the mechanical digital locks cannot be controlled freely inside and outside the door at the same time. The main reason is that the mechanical digital locks Due to the inability of the lock tongue to rebound, and currently it is not possible to directly replace other types of lock tongues, so no matter how safe and reliable the mechanical code breaking lock is, it cannot be applied to places where anti-theft doors need to be opened both inside and outside. Insufficiency greatly affects the application range of mechanical digital locks
