Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example one

Referring to fig. 1-2, a clamp for detecting the air tightness of an upper battery cover comprises a support frame 1, and is characterized in that a plurality of clamps 3 for fixing the upper battery cover 2 are arranged on the support frame 1;

referring to fig. 2, the clamp 3 comprises a cylinder 31, a connecting block 32, a lever 33, a mounting plate 34 and a pressure plate 35, and the connection is as follows:

the cylinder 31 is installed on the support frame 1, the connecting block 32 is installed on the outer surface of the cylinder 31, the cylinder 31 is provided with a piston rod, the piston rod of the cylinder 31 is rotatably connected with the lever 33, the lever 33 is rotatably connected on the connecting block 32, one end of the lever 33 far away from the cylinder 31 is fixedly connected with the mounting plate 34, and the pressing plate 35 is fixedly connected on the mounting plate 34.

In this embodiment, the pressing plate 35 may be rectangular, and the material may be rubber, metal, polymer, or the like.

The clamp 3 has the functions that the lever 33 is driven to perform lever motion through the telescopic motion of the cylinder 31, the pressure plate 35 is driven to move upwards or downwards through the mounting plate 34 when the lever 33 performs lever motion, and the battery upper cover 2 can be mounted or dismounted when the lever 33 moves upwards; when moving downwards, the edge of the upper cover 2 of the battery can be fixed.

It is worth mentioning that the hole at the connection of the lever 33 and the piston rod of the cylinder 31 should be suitably large to avoid the lever 33 from being jammed during the lever movement.
