DETAILED DESCRIPTION

[0023] The following is combined with Figures 1 to 6 The utility model is described in detail.

[0024] The utility model is an explosion-proof horizontal temperature shock test chamber, comprising a test chamber main body 1, wherein the test chamber main body 1 is provided with a high temperature test chamber 2 for performing high temperature tests and a low temperature test chamber 3 for performing low temperature tests, and the high temperature test chamber 2 and the low temperature test chamber 3 are connected to each other side by side, and the bottoms of the high temperature test chamber 2 and the low temperature test chamber 3 are both provided with slide rails 4; further comprising a movable test frame 5 and a driving mechanism 6, wherein the movable test frame 5 is movably connected with the slide rail 4, and both sides of the movable test frame 5 are provided with limit plates 51 which can seal the connection between the low temperature test chamber 3 and the high temperature test chamber 2; the driving mechanism 6 drives the movable test frame 5 to reciprocate along the slide rail 4 between the high temperature test chamber 2 and the low temperature test chamber 3; the high temperature test chamber 2 and the low temperature test chamber 3 are both provided with test doors 7, and the test doors 7 are equipped with a plurality of explosion-proof chains 71, and the test chamber main body 1 also has an explosion-proof function during the test process at extreme temperatures.

[0025] When the utility model is in use, it can not only carry out an independent high temperature test in the high temperature test chamber 2, but also carry out an independent low temperature test in the low temperature test chamber 3, and it can also combine the high temperature test chamber 2 and the low temperature test chamber 3 to carry out a temperature shock test between the high and low temperature tests, so that the tested product can obtain more comprehensive test data, and the performance of the tested product can be more comprehensively understood, with higher safety.

[0026] In order to further improve the explosion-proof function of the test chamber, the tops of the low-temperature test chamber 3 and the high-temperature test chamber 2 are both provided with explosion-proof pressure relief ports 21, and the explosion-proof pressure relief ports 21 are provided with pressure relief covers 22, one side of the pressure relief covers 22 is hinged to the test chamber body 1, and the other end is detachably connected to the test chamber body 1. When individual tested products explode due to excessive temperature and produce a high-pressure environment, the pressure relief covers 22 can be opened in time to release the gas inside the test chamber and relieve the high pressure.

[0027] Preferably, an explosion-proof chain 71 is connected between the pressure relief cover 22 and the test box body 1. Even if the pressure relief cover 22 is bounced open due to excessive pressure, it can be pulled in time by the explosion-proof chain 71, which can prevent the pressure relief cover 22 from being directly bounced open due to excessive pressure and injuring the staff. The explosion-proof chain 71 set on the test door 7 also has this function, minimizing the adverse effects of the pressure relief process.

[0028] In the present invention, a heating channel 8 is further provided at the rear end of the high temperature test box 2 , and a plurality of first air inlet holes 81 are provided above the heating channel 8 and the high temperature test box 2 , and a plurality of first air return holes 82 are provided below the heating channel 8 and the high temperature test box 2 .

The evaporator 94 and the second humidifier 95 are arranged between the second air inlet 91 and the second air return 92. The refrigeration principle of the refrigeration channel 9 is similar to that of the heating channel 8. The second air supply device 93 sucks the airflow into the refrigeration channel 9, and the airflow is introduced into the low-temperature test chamber 3 through the second air inlet. After passing through the tested product, the airflow flows back to the refrigeration channel 9 through the second air return port. The airflow passes through the second humidifier 95 and the evaporator 94 in sequence, and then flows into the low-temperature test chamber 3 after the temperature is reduced. After the above airflow cycle, the product is continuously subjected to a low-temperature test.

[0032] The test box body 1 further includes a refrigeration unit 96 disposed at the bottom of the test box body 1 . The refrigeration unit 96 is connected to the evaporator 94 to provide refrigeration power for the evaporator 94 .

The movement process of the movable test frame 5 is more stable and more convenient to use by directly connecting the movable test frame 5 to the groove at the bottom of the test chamber body 1.

[0034] Preferably, a sealing rubber ring 72 is provided on one side of the limit plate 51 close to the movable test frame 5. When the movable test frame 5 is completely moved to the high temperature test chamber 2 or the low temperature test chamber 3, the limit plate 51 abuts against the connection between the two test chambers, and the sealing rubber ring 72 is used to separate the two test chambers to form two independent test chambers.
