Mobile phone rear cover lock

Abstract

The invention discloses a mobile phone rear cover lock and relates to a lock. In order to prevent a mobile phone from being stolen, a traditional axis type lock cylinder is abandoned, lock codes and key codes are fully distributed in the three dimensions of the space, key code needle rods are directly adopted to push lock code needle rods, high secret key amount which is over trillions is achieved, microminiaturization is achieved, no key groove is needed, and a lock cylinder is high in strength. According to the lock cylinder technology adopted by the invention, a screw lock code sieve and alatch honeycomb are tightly adjacent to each other, many holes are formed in the screw lock code sieve in a two-dimensional arrangement mode, the lock codes different in code number are contained in the holes, and then a three-dimensional layout of the lock codes is formed; many nests are arranged in the latch honeycomb in a two-dimensional mode, and latches and springs are contained in the nests;and a bolt opening is formed in a mobile phone rear cover, a threaded hole and an axial hole are formed in a framework of a mobile phone, the latch honeycomb is polygonal and corresponds to the axialhole, and the outer edge of the screw lock code sieve is in a lead screw shape and is engaged with the threaded hole for locking.

Description

technical field [0001] The invention relates to a lock, in particular to a mobile phone back cover lock with a three-dimensional spatial layout of a lock code and a key code lock cylinder, and a bolt inserted into a screw hole. Background technique [0002] As we all know, mobile phones are now small and light, and mobile phones are easy to be stolen. A mobile phone is expensive, but the information stored inside is more important. Thieves who steal mobile phones worth thousands of dollars often only buy a few hundred yuan and sell them. The important information in the mobile phone is stolen and used illegally, which makes people who have stolen mobile phones very distressed. Mobile phones are different from other supplies. Mobile phones are closely related to people's lives today. It is difficult to separate them and must be carried with them. This gives the thief many opportunities. .

[0002] As we all know, mobile phones are now small and light, and mobile phones are easy to be stolen. A mobile phone is expensive, but the information stored inside is more important. Thieves who steal mobile phones worth thousands of dollars often only buy a few hundred yuan and sell them. The important information in the mobile phone is stolen and used illegally, which makes people who have stolen mobile phones very distressed. Mobile phones are different from other supplies. Mobile phones are closely related to people's lives today. It is difficult to separate them and must be carried with them. This gives the thief many opportunities.

Why can't mobile phones be installed with anti-theft locks? Mobile phones are not equipped with anti-theft locks. One is that the mobile phone is too small, which is different from large items such as cars, which can be locked to prevent theft. The lock is useless, the stealing is correct

Therefore, the current anti-theft methods for mobile phones are to use various anti-theft software. The shortcomings of these anti-theft software are obvious. By removing the battery and mobile phone card, and modifying the system by hackers, it can be easily solved.

[0003] 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 few digits, and the key quantity is only a few thousand. The key rate is low, the material strength of the lock cylinder is small, and the lock cylinder The smaller the size, the smaller the difference between the size of pins and pins of different code numbers, not only the amount of keys is reduced, but also very close to the error rate necessary for traditional lock cylinder technology, so the smaller the lock, the easier it is to unlock technically , plus the necessary linkage mechanism, it is technically difficult to make the traditional mechanical lock into a screw lock, and it has no use value
