Problems solved by technology

[0006] The structure of the lock cylinder determines the difficulty of preventing technical opening. From the structure of the prior art, it can be seen that it does not break away from the foundation of the pin code, but is superimposed on it. This superposition only increases the difficulty of technical opening. , but it does not solve the problem fundamentally, and the key mutual opening rate is still very high

Embodiment 1

[0019] A mechanical double coding method for a lock cylinder, in which a mechanical coding group composed of several chips with coding functions is set in the lock cylinder, and each code chip is provided with a coding structure corresponding to a key, when the coding structure of the key is the same as that of the mechanical When the coding structure of the coding group is corresponding, the key is rotated to open the lock cylinder, otherwise, the code chip does not help the movement of the lock cylinder in the lock cylinder according to the structure of the lock cylinder.

[0020] At least one inner opening 2 is set on the code chip 1 for passing through the key, a position coding mechanism 3 for positioning and coding is set on the code chip inner opening, and at least one is set on the outer surface of the code chip 1 for The fixed coding mechanism 4 of the fixed coding, the described fixed coding mechanism 4 and the positioning coding mechanism 3 mechanisms set a correlati...

Embodiment 2

[0024] A kind of mechanical double coding method of lock cylinder, such as figure 1 As shown, the code chip 1 is a cylinder, and its inner opening 2 is a combination of an arc hole and a square. The positioning encoding mechanism 3 is a protrusion or groove arranged on the inner opening, and the fixed encoding mechanism 4 is arranged on the inner opening. The protrusions or grooves on the outer surface of the cylinder, the protrusions or grooves are circular, arc-shaped, polygonal or a combination of these structures, with the position of the center line of the positioning coding mechanism 3 as the initial value 0, and the position coding The angle from the center line of the mechanism 3 to the edge is used as the positioning coding value, and the angle generated between the fixed coding mechanism 4 and the positioning coding mechanism 3 in the clockwise or counterclockwise direction is used as the associated value.

[0025] Such as figure 1 In the above, the angle from the c...

Embodiment 3

[0029] As a kind of chip structure, the cross-sectional shape of the chip 1 is an arc shape less than 360°, and its inner opening 2 is an arc hole, a polygon hole or a combination of these structures, and the positioning coding mechanism 3 is arranged on the The protrusion or groove on the inner opening, the fixed coding mechanism 4 is a protrusion or groove arranged on the outer surface of the arc, and the protrusion or groove is arc-shaped, polygonal or a combination of these structures to locate The position of the centerline of the encoding mechanism is the initial value, the angle from the centerline of the positioning encoding mechanism to the edge is used as the encoding value, and the angle generated between the fixed encoding mechanism and the positioning encoding mechanism in the clockwise or counterclockwise direction is used as the associated value.

Abstract

The invention discloses a mechanical dual-coding method of a key cylinder. A mechanical coding assembly which consists of a plurality of chips with a coding function is arranged in the key cylinder; each chip is provided with a coding structure which corresponds to a key; when the coding structure of the key corresponds to the coding structure of the mechanical coding assembly, the key cylinder can be unlocked by rotating the key; and if the coding structure of the key does not correspond to the coding structure of the mechanical coding assembly, the chips move in the key cylinder but the key cylinder cannot be unlocked. The range of an existing spring lock is broken through, mechanical coding is realized by a positioning structure and a coding mechanism, mutual unlocking rate is zero in theory on the basis of cold values of coding, electronic decoding and manual decoding cannot be implemented by mechanical coding, high protection is realized, and technical unlocking cannot be implemented.

Description

technical field [0001] The invention relates to a mechanical double coding method of a lock cylinder, which belongs to the technical field of lock production. Background technique [0002] Existing lock core, its basic principle is: a row of apertures are arranged in the lock core, in the apertures are copper pillars and springs of different lengths, and the outside is sealed with aluminum. Usually, the copper pillar pops out half of it due to no force, thus blocking the rotation of the lock cylinder. When the corresponding key is inserted, the copper column and the teeth on the key contact to form a regular curve, which corresponds to the opening of the lock, so that the lock cylinder can be rotated. [0003] The lock cylinder is divided into three levels according to the difficulty of anti-technical opening, A-level is basic, B-level is anti-theft, super B-level is more than B-level anti-theft ability (the national standard does not have this statement, this is the genera...
