Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present utility model. It will be apparent, however, to one skilled in the art that the utility model may be practiced without one or more of these details. In other instances, well-known features have not been described in detail in order to avoid obscuring the utility model.

The utility model provides a battery constant temperature test box, which comprises a box body 1, wherein a plurality of groups of partition boards 2 are distributed in the box body 1, and at least two groups of partition boards 2 are arranged for placing batteries to be detected. The two ends of the partition board 2 are provided with convex connecting ends 201; the limiting plate 3 is connected to the inner side of the box body 1 in a sliding manner and distributed on two sides of the partition plate 2, a plurality of straight notch 301 are formed in the limiting plate 3, and the connecting end 201 is correspondingly and cooperatively connected with the straight notch 301; the fixed plate 4 is arranged at the side end of the limiting plate 3, a plurality of displacement holes 401 are formed in the fixed plate 4, and the limiting plate 3 moves up and down along the displacement holes 401. When the baffle plate 2 and the limiting plate 3 are combined for use, the connecting end 201 on the baffle plate 2 is matched and connected with the corresponding straight slot 301 on the limiting plate 3, the protruding height of the connecting end 201 in the initial state is slightly larger than the thickness of the fixing plate 4, and the limiting plate 3 is connected to the limiting plate 3 and is provided with a gap with the fixing plate 4. The two sides of the limiting plate 3 are connected with the inside of the box body 1 through sliding rails so as to facilitate the lifting movement of the pushing separation plate 2. The limiting plate 3 moves up and down in the box body 1 along the sliding rail, so that the distance between the partition plates 2 is changed. When the battery testing device is used, the distance between the adjacent partition boards 2 can be adjusted according to different sizes of the batteries, so that the batteries are ensured to be placed orderly, and the battery testing device is suitable for testing requirements of various batteries.
