Three-dimensional code bolt-external lock

Abstract

The invention discloses a three-dimensional code bolt-external lock, and relates to a lock. In order to overcome the defects that existing mechanical lock secret key amount is small, the lock cylindermaterial strength is small, and the spring bolt manner is weak, a traditional axis type lock cylinder is abandoned, lock codes and key codes are sufficiently distributed, a key code needle rod directly pushes a lock code needle rod, and the high-strength lock cylinder with the higher than trillion high secret key amount is achieved. A lock cylinder technology is adopted, a lock code sieve and a bolt honeycomb are tightly attached, many holes are distributed on the lock code sieve according to a two-dimensional manner, lock codes with multiple code numbers are installed in the holes, and three-dimensional distribution of the lock codes is formed; and many nests are arranged in the bolt honeycomb according to a two-dimensional manner, bolts and springs are installed in the nests, a screw shaft rod is connected to the lock code sieve and is divided into a shaft rod part and a screw part, the outer surface of the bolt honeycomb is polygonal, the screw part and a screw pipe are meshed andlocked in cooperation with a corresponding axial pipe, and fastening pieces can be connected to the outer edges of the axial pipe and the screw pipe.

Description

technical field [0001] The invention relates to a lock, especially a lock core with a lock code and a key code arranged in a three-dimensional space, and a lock with a bolt inserted into a screw hole. 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, usuall...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortcomings of existing mechanical locks such as low key rate, small strength of lock cylinder material, and low prying resistance of the door buckle, the present invention abandons the traditional key shank, shaft-type lock cylinder, and key slot, and directly uses the key code The needle bar pushes the lock code needle bar, so that the layout of the lock code and the key code can be released and expanded in space. Compared with the traditional mechanical lock, the present invention can fully arrange the lock code in three dimensions of space And key code, achieve high key volume, miniaturization, no key slot, high-strength lock cylinder
