Problems solved by technology

Although some clutch-type lock heads and pin lock cylinders disclosed at present can solve the basic anti-theft function, the mutual opening rate of keys is high, the key quantity of the lock cylinder is small, and the structure of the lock cylinder is complicated, and the processing is difficult. Therefore it is necessary to design a coding and decoding mechanism for locks with strong anti-technical opening capability and a large amount of coding information.

Embodiment 1

[0034] Such as figure 1 Shown encoding mechanism, key 1 and clutch pin 6. The encoding mechanism includes a plurality of encoding slices 2, and its structure is as follows: figure 2 As shown, the encoding sheet 2 is in the shape of a circular ring, and a plurality of encoding sheets are divided into N types. The outer edge of the first type of encoding sheet 21 has a clutch groove 211 for the first type of encoding sheet, and the inner edge of the ring is provided with The bump that protrudes toward the center of the ring has a first-type coding piece tooth groove 212 on the bump; the second-type coding piece 22 has a second-type coding piece clutch groove 221 on the outer edge of the ring, and the inside of the ring The edge is provided with a protruding block protruding toward the center of the ring, and the second type coding piece tooth groove 222 is opened on the projection; the third type coding piece 23 has a third type coding piece clutch groove 231 on the outer edge...

Embodiment 2

[0054] Such as Figure 13 As shown, in this embodiment, the structure of the guide shaft 301 and the key 101 is different from that of Embodiment 1. The key 101 has only one rack, and there are four kinds of gear blocks with different heights on the rack, and the corresponding guide shaft 301 is also corresponding. There is only one bar-shaped hole, and each coding piece has 1 reset block and 4 layers of stepped tooth grooves. One of the tooth grooves of the same layer of coding pieces meshes with one of the tooth pieces, but on each coding piece, the clutch groove Groove is different from the same position of cog. Other structures are the same as in Embodiment 1.

Embodiment 3

[0056] Such as Figure 14 As shown, in the present embodiment, the structures of the coding piece and the key 102 are different from those of the first embodiment. Each coding piece has a reset block and a tooth groove, and there are 4 racks on the key 102, and each toothed rack has a There is only one kind of tooth block, but on each coding piece, the same position of the clutch groove and the tooth groove is different. Other structures are the same as in Embodiment 1.

[0057] In Embodiment 2 and Embodiment 3, since the racks on the key and the number of slots on the coding sheet are small, although this technical method can also be realized, the amount of coding information is small. Theoretically, the value of encoding information is infinite, but in the physical design, factors such as the size of the structure, the difference in encoding angle, and the performance of processing technology should be considered for comprehensive evaluation.

Abstract

The invention discloses a coding mechanism and key for a clutch type clock. A clutch pin is arranged in the lock and is in linkage with an unlocking mechanism, the coding mechanism is arranged in the lock and comprises multiple coding plates, bumps on the coding plates are provided with reset blocks and toothed grooves, the bumps on each coding plate are the same, positions, relative to clutch grooves, are not exactly the same, the multiple coding plates are stacked in the axial direction, the circle centers of circular rings are coaxial, multiple toothed blocks are arranged on the key, when the key is inserted into the coding mechanism to rotate, the multiple toothed blocks of the key are meshed with the multiple toothed grooves of the coding plates successively to drive the coding plates to rotate, and the clutch grooves of the coding plates are right opposite to the clutch pin; when the key is rotated reversely, the key drives a reset bar to be meshed with the multiple reset blocks of the coding plates successively, all the reset blocks of the coding plates are rotated to the same direction, and the clutch grooves are not in the same direction. According to the coding mechanism and key for the clutch type clock, the coding information content produced by the coding mechanism is large, and the capacity of controlling technical opening is strong.

Description

technical field [0001] The invention relates to a lockset, in particular to a coding mechanism of a clutch lock head and a key matched therewith. Background technique [0002] The lock cylinder is the most critical part of the lock, which determines the anti-theft performance of the lock. At present, there are pin locks commonly used in daily life. Safety performance against technical opening. The invention of the clutch lock head greatly improves the ability to prevent non-technical opening, especially improves the ability to prevent rotation torque damage. Although some clutch-type lock heads and pin lock cylinders disclosed at present can solve the basic anti-theft function, the mutual opening rate of keys is high, the key quantity of the lock cylinder is small, and the structure of the lock cylinder is complicated, and the processing is difficult. Therefore be necessary to design a kind of encoding and decoding mechanism that anti-technical opening ability is strong, t...
