an electronic locking device comprises a bottom shell, wherein a gear train and a motor are installed in the bottom shell, the gear train is connected with an output gear of the motor in a matching mode, the gear train is fixed in the bottom shell through screws, and a manual unlocking device is installed at the lower end of the gear train and the bottom shell; a PCBA circuit board is further installed in the bottom shell, and the motor is assembled on the PCBA circuit board; the gear train is provided with a rack, and the rack is provided with a rack inclined plane side pressure structure for locking and unlocking; the motor is provided with an upper cover, and the upper cover and the bottom shell are mounted in a closed mode to form an integral electronic locking device.

Preferably, the lower end of the bottom shell is further provided with a rubber piece.

Preferably, the PCBA circuit board further comprises a remote control end, and the remote control end is in wired connection with the PCBA circuit board through a cable or a connector.

Preferably, two position feedback switches are also mounted on the PCBA circuit board).

Preferably, the rubber member is of a laminated structure.

Preferably, the gear train is provided with a cam structure and a boss, and the cam structure on the gear train is supported on the boss.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses an electron locking means is owing to increase the cam structure on the gear train and promote the electronic lock holding power, mistake pull out rifle/steal rifle in the time of can effectively preventing to charge, adopts simultaneously to fold and fold formula structure rubber seal spare and promote locking mechanism waterproof reliability.
