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.
