Description

Technical Field

[0001] This utility model relates to the field of test chamber technology, specifically to a high and low temperature alternating damp heat test chamber. Background Technology

[0002] High and low temperature alternating test chambers are essential testing equipment in aerospace, automotive, home appliance, and scientific research fields. They are used to test and determine the parameters and performance of electrical, electronic, and other products and materials after undergoing temperature environment changes such as high temperature, low temperature, or constant temperature testing. As the requirements of testing projects continue to change, high and low temperature alternating test chambers also require specified humidity control to make the tests more accurate.

[0003] Currently, Chinese patent publication number CN211026369U discloses a high and low temperature alternating damp heat test chamber, including a test chamber body and a control box. The control box is fixedly installed at the lower end of the test chamber body. A bearing seat is welded to the lower end of the interior of the test chamber body, and a bearing is installed inside the bearing seat. A support rod is sleeved inside the bearing, and a loading tray is welded to the outside of the support rod. A first square groove is opened inside the support rod. This utility model, by designing a bearing seat inside the test chamber, installing a bearing inside the bearing seat, installing a support rod inside the bearing, and designing three loading trays outside the support rod, also installs a spring and a first square rod inside the support rod. A chuck is designed at the upper end of the square rod. The chuck cooperates with a second square rod at the lower end of the motor shaft to form a rotation mechanism, which allows the loading trays to rotate. This allows the products on the loading trays to rotate during high and low temperature transitions, making the products more uniformly subjected to temperature changes, which is beneficial to the test.

[0004] In the above solution, the distance between the trays is fixed and cannot be adjusted, which is not convenient for heat dissipation of products of different sizes. In addition, the filter screen in the above solution is fixed, which is not convenient for cleaning and replacement. Therefore, there is an urgent need for a high and low temperature alternating damp heat test chamber to solve the above problems. Utility Model Content

The bending rod 231 slides stably along the direction of the slide rod 234 and compresses the spring 233 until one end of the bending rod 231 disengages from the positioning hole 235 on one side of the rectangular column 21. Then, the placement tray 22 can be dragged up or down to adjust its position. After adjusting to the appropriate position, release the bending rod 231. Under the restoring force of the spring 233, the bending rod 231 will enter the positioning hole 235, thus achieving the adjustment of the placement tray.
