The battery box locking mechanism comprises a bolt shaft, a shell, a sliding sleeve, a meshing end plate, a base, springs and a cover plate, the bolt shaft is arranged in the shell, the bolt shaft is sequentially sleeved with the sliding sleeve, the meshing end plate and the base, and the sliding sleeve, the meshing end plate and the base are limited through the springs; vertical bosses are uniformly distributed on the inner wall of the shell; the plum-blossom-shaped angle structure on the lower part of the bolt shaft is matched with the plum-blossom-shaped angle structure on the inner hole of the sliding sleeve; the meshing end plate is meshed with meshing teeth on the sliding sleeve; the bottom of the base is in coaxial clearance fit with the bottom of the shell; the springs comprise the first spring and the second spring, the first spring is arranged between the shaft shoulder and the meshing end plate, and the second spring is arranged between the sliding sleeve and the base. And the counter bores and the through holes which are formed in the cover plate at intervals correspond to the first fixing holes and the second fixing holes in the shell respectively. The device is reasonable in structural design and easy and convenient to operate, the battery box can be rigidly and reliably fixed, and the battery box is effectively prevented from loosening in a vibration environment.
