Embodiment 1

[0052] A kind of planar dot-matrix coding safety lock, its structure comprises key 1, lock core 3 and lock body guard 2 outside the lock core; The inside of the lock body guard is divided into two chambers, which are respectively used for reversing the key. The reversing cavity 204 and the lock cylinder chamber 205 where the lock cylinder is located, the key is correspondingly fitted on the lock cylinder through the key hole provided by the lock body shield. The structure and process are simple, and the processing cost is low. The lockset described in this patent only consists of three parts: a lock cylinder, a shield and a key, without a precise linkage mechanism, so the structure and process are simple, and the processing cost is low. The structure of the lock is only composed of the lock core and the shield. During the process of opening and closing the lock, the lock core directly drives the linkage system, and the overall strength can be infinitely improved, preventing th...

Embodiment 2

[0054] A kind of planar dot-matrix coding safety lock, its structure comprises key 1, lock core 3 and lock body guard 2 outside the lock core; The inside of the lock body guard is divided into two chambers, which are respectively used for reversing the key. The reversing cavity 204 and the lock cylinder chamber 205 where the lock cylinder is located, the key is correspondingly matched with the lock cylinder through the key hole provided by the lock body shield, and the key holes on the lock body shield are two places, one The top keyhole 202 that is opened for the upper end of the reversing chamber to allow the key to enter the reversing chamber, and the other is the middle keyhole 203 between the reversing chamber and the lock cylinder chamber, the top keyhole and the middle key The hole orientation is different.

[0055] The key hole of the lock adopts a labyrinth reversing design, and the key handle and the opening part are perpendicular to each other. In the absence of a k...

Embodiment 3

[0057] A kind of planar dot-matrix coding safety lock, its structure comprises key 1, lock core 3 and lock body guard 2 outside the lock core; The inside of the lock body guard is divided into two chambers, which are respectively used for reversing the key. The reversing cavity 204 and the lock cylinder chamber 205 where the lock cylinder is located, the key is correspondingly matched with the lock cylinder through the key hole provided by the lock body shield, and the key holes on the lock body shield are two places, one The top keyhole 202 that is opened for the upper end of the reversing chamber to allow the key to enter the reversing chamber, and the other is the middle keyhole 203 between the reversing chamber and the lock cylinder chamber, the top keyhole and the middle key The hole orientation is different. The key is composed of a handle 102 and a key frame 101 at the front end of the handle, and the lock core is composed of a lock core plate 302 and a lock core shaft ...

Abstract

The invention provides a planar lattice coding safe lock comprising a key, a lock core and a lock body protective cover which is arranged outside the lock core; the inside of the lock body protective cover is divided into two chambers, i.e. a reversing chamber which reverses the key and a lock core chamber in which the lock core is located; and the key is correspondingly matched on the lock core through a key hole on the lock body protective cover. The key comprises a handle and a key rack which is arranged on the front end of the handle, and the lock core comprises a lock core plate and a lock core shaft which is arranged below the lock core plate; and a lattice shaft which is arranged on the key rack is correspondingly matched on a coding band which is arranged on the lock core plate. The lock core adopts a planar irregular hollow lattice coding technology to code three-dimensionally, so that a coding space is extended infinitely, and the coincident code probability is zero theoretically. The protruded lattice of the key is matched with the hollow hole lattice code of the lock core, a lattice protruded column which corresponds to the planar irregular hollow lattice is adopted, so that the portability for carrying and using of the planar lattice coding safe lock is not affected when a high-strength material is adopted.

Description

technical field [0001] The invention relates to a lock, in particular to a plane dot matrix coding safety lock. Background technique [0002] Mechanical locks have a history of more than 3,000 years as unlocking tools, and are essential tools for protecting family personal or social wealth and rights. With the development of society and the progress of science and technology, it changes with each passing day in form, and its production precision continues to increase. It is widely used in people's daily life and work, and is closely related to people's lives. [0003] All kinds of mechanical locks and locking devices are created on the basis of various mechanical principles. The function of the key is to make corresponding changes in the locking mechanism in the lock. In the process of unlocking (decoding), only when the key code and the lock code are identified and matched in the mechanism can the lock bolt and lock be activated through the transmission parts. Tongue acti...
