Bolt lock and key

Abstract

The invention discloses a bolt lock and a key, and relates to a lock. In order to overcome the defects that an existing mechanical lock is low in key amount, is small in strength of a lock cylinder material, and is weak in a lock tongue way. A conventional axis type lock cylinder and a conventional lock tongue are cancelled, and a screw locking method is adopted, so that encodes and key codes aresufficiently arranged on three dimensions of the space, and therefore, a lock cylinder with high key amount and high strength is achieved. According to the technology adopted by the invention, an encode screen and a bolt screen are tightly adhered, the encode screen is provided with a plurality of axial encode holes, encodes and ejector pins of various models are arranged in the holes, multiple axial bolt holes are formed in the bolt screen, bolts and springs are arranged in the holes, the encode screens are connected to screw shaft levers, the appearance of the bolt screen is polygonal, the bolt screen is matched with the corresponding axial hole part, the screw part is engaged and locked with the screw hole part, key codes of various models are connected on the end surface of a key codesupport, and the rear end of the key code support is provided with a cylindrical handle.

Description

technical field [0001] The invention relates to a lock, in particular to a lock cylinder whose end faces are relatively rotated and which is engaged and locked by bolts. Background technique [0002] At present, mechanical locks are mainly pin locks and blade locks with key slots. Because the processing of key slots is difficult, the material of the lock cylinder can only use low-strength brass. The existing pin lock cylinder uses an axial lock cylinder. This requires that there must be a key slot and a key handle rod, the pins are arranged in a linear arrangement, and the key teeth are also arranged in a linear manner. The concave and convex angle of the key teeth must be less than about 45 degrees to facilitate insertion into the lock cylinder, so that the longest pin and the shortest pin The differential length cannot be much larger than the diameter of the marbles, which greatly limits the number of marbles and the number of marbles, usually only a single digit, and the ...

Problems solved by technology

[0004] In order to overcome the shortcomings of the existing mechanical locks, such as low key rate, low strength of the lock core material, and fragile lock tongue, and to solve the problem of anti-theft and anti-loosening of outdoor machinery and equipment, the present invention abandons the traditional key handle and shaft-type lock core, And the key slot, directly push the lock code needle bar with the key code needle bar, like this, the layout of the lock code and the key code, just can be released and expanded in space, compared with the traditional mechanical lock, the present invention can be in the three In three dimensions, the lock code and key code are fully arranged to achieve high key volume, miniaturization, no key slot, and high-strength lock cylinder
