[0031] In a specific embodiment of the present invention, the box body 1 serves as the main structure for providing a high and low temperature test environment. An explosion-proof mechanism is provided inside the box body 1. The mating rotator 2 is installed in the box body 1 for transmitting the rotational force. The first rotating shaft 3 is connected to the mating rotator 2 and drives the support rod 4 to move by rotation.

[0040] For details, please refer to Figures 1-4The front end of the box body 1 is rotatably connected to two cabinet doors 15, the front end of the box body 1 is fixedly connected to a controller 16, the rear end of the cabinet door 15 is fixedly connected to a second explosion-proof partition 8, and the other second explosion-proof partition 8 is fixed on the inner wall of the box body corresponding to the cabinet door 15. After the first explosion-proof partition moves to a specified position, it fits with the other second explosion-proof partition 8, and then after closing the cabinet door 15, the two first explosion-proof partitions and the two second explosion-proof partitions will form an explosion-proof space.

[0041] In this embodiment: the cabinet door 15 is connected to the front end of the box body 1 by rotation and can be easily opened and closed, ensuring that the operator can easily access the test samples. The controller 16 is installed at the front end of the box body 1 to control the temperature changes and other parameter settings in the box body 1.

[0042] The working principle and use process of the present invention are as follows: first, the device is started through the controller 16 to prepare for the high and low temperature impact test, then the cabinet door 15 is opened, and the test part is placed on the experimental platform 13. According to the size and position requirements of the test part, the adjusting rod 6 is rotated to adjust the first explosion-proof partition 5 to the required position, and then the position of the adjusting rod 6 is fixed by the fixing pin 603. Then, the second explosion-proof partition 8 on the front side of the first explosion-proof partition 5 works together with the first explosion-proof partition 5 to form a multiple protection barrier to ensure the stability of the test part. Finally, the cabinet door 15 is closed, and the high and low temperature impact parameters are set through the controller 16 to start. The heating or cooling system, the cold air outlet 9 provides a low-temperature environment, and the centralized heating pipe 10 and the hot air outlet 12 provide a high-temperature environment to ensure that the test parts experience high and low temperature shocks. After the test is completed, the cabinet door 15 is opened, the test parts are taken out, and the equipment is turned off. By using this device, the explosion risk caused by the lack of appropriate explosion-proof protection parts inside the traditional high and low temperature shock box is solved. If there is flammable gas or liquid in the test box and there are no effective explosion-proof protection measures, once an ignition source appears, it may cause an explosion accident and fire hazards. Even if there is no complete explosion, it may also cause a fire due to overheating or other reasons.
