Description
Technical field
The present invention relates to the electronic lock provided with sliding block avoiding mechanism, is a kind of limited unlocking electronic lock.
Background technology
Door lock is a kind of equipment for being used for door lock to live, and is generally divided into mechanical, electronic, coded lock etc., some of door locks
For metal cabinet door or control device screen, such cabinet lock is mainly used in opening for the metal cabinet doors such as power distribution cabinet, file cabinet, locker
Close；And the electronic lock for being used for above-mentioned cabinet door generally requires forceful electric power or light current provides unlocking power；According to the mode of its electronic induction
Difference, it is divided into electronic password lock, electronic induction lock etc..Existing some intelligent electronic locks used in the industry use dual-coil electromagnetic valve knot
Structure, its operation principle usually break movable slider by a magnetic valve, complete work of locking, another is normal open electricity magnetic valve.Work as door
After locking closes, normal open electricity magnetic valve pins mechanical latch always, and in the case where there is electricity, mechanical key is limited, it is desirable to Wu Fakai
Open, only in the event of a loss of power, after normal open electricity magnetic valve automatically springs open, mechanical key can be opened.But such smart electronicses
The maximum application problem of lock is：After magnetic valve normal open electricity, easily generate heat perishable, when normal open electricity magnetic valve bad after, mechanical key is with regard to energy
Open, so as to not reach the limited purpose of mechanical key.
The content of the invention
To overcome above-mentioned deficiency, the purpose of the present invention is to provide a kind of limited unlocking electronic lock to this area, makes its solution
Existing like product structure design is not good enough, causes stability not good enough, the technical problem being further improved.The purpose is to pass through
