[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0020] See Figure 1-3An explosion-proof high and low temperature test device includes a chamber 1, with support legs at the bottom of the chamber 1. Bearing seats 2 with built-in bearings are set on the left and right sides of the bottom of the chamber 1. A lead screw 3 is set between the bearing seats 2. One end of the lead screw 3 is connected to a motor 4 for transmission. A slider 5 is threadedly connected to the lead screw 3. A strip hole 6 is opened on the bottom plate of the chamber 1. The slider 5 is set through the strip hole and a material discharge groove 7 is set on the slider 5. The material discharge groove 7 includes a bottom plate, a left side plate and a right side plate. A high temperature chamber 8 and a low temperature chamber 9 are respectively set on the left and right sides of the chamber 1. The high temperature chamber 8 and the low temperature chamber 9 have the same structure and no bottom plate. They are open at the end facing the material discharge groove. A hot air blower 10 is set on the top of the high temperature chamber 8. The hot air blower 10 is connected to the high temperature chamber 8 by a pipe. The high temperature chamber is also connected to an explosion-proof mechanism 11. A cold air blower 12 is set on the top of the low temperature chamber 9. The cold air blower 12 is connected to the low temperature chamber 8 by a pipe. Specifically, the test sample is placed in the discharge trough 7, and the motor 4 drives the lead screw 3 to rotate. The lead screw 3 drives the slider 5 to move along the strip hole 6. The discharge trough 7 first moves into the high-temperature chamber 8, and the test sample is tested in a hot environment by the hot air blower 10. After the test is completed, the motor 4 rotates in the opposite direction, and the discharge trough 7 enters the low-temperature chamber 9, where the test sample is tested in a cold environment by the cold air blower 12. This alternating switching can realize the alternating hot and cold environment test of the product. When the discharge trough 7 enters the high-temperature chamber 8 and the low-temperature chamber 9, the left and right side plates simultaneously seal the openings of the high-temperature chamber 8 and the low-temperature chamber 9, thereby improving the sealing and facilitating the test.

[0021] In this embodiment, the explosion-proof mechanism 11 includes a nitrogen cylinder 111, which is connected to the high-temperature chamber via a pipeline, and a regulating valve 112 is provided on the outlet of the nitrogen cylinder. Nitrogen gas is introduced into the high-temperature chamber 8 through the nitrogen cylinder 111, thereby reducing the probability of explosion, and the regulating valve 112 can adjust the input amount.

[0023] In this embodiment, temperature sensors (not shown in the figure) are installed inside the high-temperature chamber 8 and the low-temperature chamber 9, and a temperature display 15 is installed externally. The temperature display 15 is electrically connected to the temperature sensors. The temperature display 15 and the temperature sensors are used to monitor the temperature inside the high-temperature chamber 8 and the low-temperature chamber 9, thereby facilitating observation and operation.

[0024] In this embodiment, the inner walls of both the high-temperature chamber 8 and the low-temperature chamber 9 are provided with insulation layers to improve the insulation effect of the high-temperature chamber 8 and the low-temperature chamber 9 and ensure the quality of the test.
