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 lock with strong anti-technical opening ability and large amount of encoded information.

Embodiment 1

[0042] Such as Figure 1 to Figure 3 The shown lock head includes a clutch type lock cylinder, a transmission mechanism and a lock sleeve.

[0043] The bottom of the lock sleeve 9 is cylindrical, and the outer wall of the lock sleeve 9 is provided with two pin holes connected to the inside of the lock sleeve, which are respectively a jack pin hole 91 and a limit pin hole 92, and a slidable jack is placed in the jack pin hole 91. Pin 71, a slidable stop pin 72 is placed in the stop pin hole 92, and the two pin holes can be set as blind holes, and a spring is installed between the bottom of the blind hole and the top pin 71 and the stop pin 72 (not shown in the figure). ), to facilitate the movement of the ejector pin 71 and the limit pin 72. The inner wall of the sleeve of the locking sleeve 9 is provided with a groove, the groove extends in the axial direction, and the groove intersects with the pin hole.

[0044] The transmission mechanism includes an inner sleeve 8, an eje...

Embodiment 2

[0066] Such as Figure 18 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

[0068] Such as Figure 19 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.

[0069] 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

An on-off type lock and a key. The lock comprises an on-off type lock cylinder, a transmission mechanism and a lock sleeve (9); the key (1) is matched with the lock cylinder; the transmission mechanism comprises an inner sleeve (8), a lifting pin (71), a limiting pin (72) and an on-off pin (6); the lock cylinder rotates to form an on-off through groove (200), the lower part of the on-off pin (6) enters the on-off through groove (200) after the on-off pin (6) is extruded by the lifting pin (71), and the upper part of the on-off pin (6) is located in an on-off pin strip-shaped hole (81) of the inner sleeve (8), so that linkage unlocking between the lock cylinder and the inner sleeve (8) is realized; and after the lock cylinder rotates reversely and is locked, the limiting pin (72) limits the inner sleeve (8) from continuously rotating, the lock cylinder continues rotating reversely to extrude the lower part of the on-off pin (6) into the on-off pin strip-shaped hole (81), and the upper part of the on-off pin (6) enters a groove of the lock sleeve (9), so that linkage between the lock cylinder and the inner sleeve (8) is removed.

Description

technical field [0001] The invention relates to a clutch type lock head and a key matched with the lock head. Background technique [0002] Anti-theft door locks are a daily necessity. Existing anti-theft locks generally include lock operating systems, lock cylinders, and transmission mechanisms. There have been many developments and their safety performance has been greatly improved. However, in terms of structural design and stability There are still deficiencies; the lock cylinder is the most critical part of the lock, which determines the anti-theft performance of the lock head. At present, there are pin locks commonly used in daily life. , has a very high security 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 a...
