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 ...
