[0029] The utility model provides an improved air pressure simulation test box for battery testing. The technical solution of the utility model is:

[0030] like Figure 1-Figure 5 As shown, a pressure simulation test box for battery testing includes a pressure simulation test box body 1, a fixed shell 2 is arranged on the side wall of the pressure simulation test box body 1, a T-slot 3 is opened through the side wall of the fixed shell 2, a plurality of groups of resistance springs 4 are connected with equal intervals on the side wall of the inner cavity of the T-slot 3, an anti-collision plate 5 is connected between the plurality of groups of resistance springs 4 on the side away from the inner cavity side wall of the T-slot 3, a fixing component 6 is slidably arranged on the top of the fixed shell 2, and the bottom of the fixing component 6 extends downward into the inner cavity of the T-slot 3, a T-block 7 which cooperates with the T-slot 3 is arranged on the side of the pressure simulation test box body 1 which is away from the fixed shell 2, and a fixing groove 8 which cooperates with the fixing component 6 is opened on one side of the top of the T-block 7.

[0031] Furthermore, the fixing assembly 6 includes a fixing rod 601 slidably arranged on the top of the T-slot 3, and the fixing rod 601 extends downward into the inner cavity of the T-slot 3, and a mounting plate 602 is connected to the top of the fixing rod 601, and a fixing spring 603 is wound around one side of the fixing rod 601 outside the T-slot 3, and the fixing spring 603 is connected between the top of the fixing shell 2 and the bottom of the mounting plate 602. When in use, multiple groups of air pressure simulation test box main bodies 1 are pushed to be arranged horizontally, so that the T-blocks 7 of two adjacent groups of air pressure simulation test box main bodies 1 are displaced into the T-slots 3. In the process of the T-blocks 7 being displaced into the T-slots 3, the T-blocks 7 first push the fixing rods 601 upwards. When the fixing grooves 8 at the top of the T-blocks 7 are displaced to the bottom of the fixing rods 601, the fixing rods 601 are inserted into the fixing grooves 8 under the action of the elastic force of the fixing springs 603. With the help of the fixing rods 601, the T-blocks 7 are limited and fixed, thereby realizing the limited and fixed positions of the two adjacent groups of air pressure simulation test box main bodies 1. At the same time, the resistance springs 4 and the anti-collision plates 5 cooperate with each other to reduce the vibration caused by the collision between the adjacent air pressure simulation test box main bodies 1 during the assembly process.

[0032] Among them, universal wheels 10 are arranged at the four corners of the bottom of the air pressure simulation test box body 1 , and the arranged universal wheels 10 facilitate the movement of the air pressure simulation test box body 1 .

The bottom of the fixing rod 601 is wedge-shaped, and the fixing slot 8 is a wedge-shaped slot that cooperates with the fixing rod 601, which facilitates the T-block 7 to push the fixing rod 601 to move upward. A pull ring 9 is connected to the top of the mounting plate 602, and the pull ring 9 is provided to facilitate pulling the fixing rod 601.

[0034] Working principle: When in use, push multiple groups of air pressure simulation test box main bodies 1 to be arranged horizontally, so that the T-blocks 7 of two adjacent groups of air pressure simulation test box main bodies 1 are displaced into the T-slots 3. In the process of the T-blocks 7 being displaced into the T-slots 3, the T-blocks 7 first push the fixing rod 601 upwards. When the fixing slot 8 at the top of the T-block 7 is displaced to the bottom of the fixing rod 601, the fixing rod 601 is inserted into the fixing slot 8 under the action of the elastic force of the fixing spring 603. With the help of the fixing rod 601, the T-block 7 is limited and fixed, thereby realizing the limited fixation of the two adjacent groups of air pressure simulation test box main bodies 1. At the same time, the resistance spring 4 and the anti-collision plate 5 cooperate with each other to reduce the vibration caused by the collision between the adjacent air pressure simulation test box main bodies 1 during the combination process.
