Description

technical field [0001] The invention belongs to the field of locks, in particular to an intelligent padlock. Background technique [0002] At present, the mechanical locks commonly used in street lamps, substations, and power supply boxes are easily damaged, especially in the wild, where the environmental conditions are harsh and the locks are easily damaged. Now there are some smart padlocks, but these locks require active power supply. The power supply cannot work, and the maintenance is not timely after the lock is broken, which will easily cause great losses. So how to design a kind of indestructible a kind of intelligent padlock becomes the problem demanding prompt solution in this area. Contents of the invention [0003] In view of this, the present invention aims to provide a smart padlock that is not easily damaged. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] An intelligent padlock,...
