Description

Technical Field

[0001] The utility model relates to the technical field of test chambers, and particularly relates to an expandable test chamber with convenient product loading and unloading. Background Art

[0002] The actual temperature and humidity sensed by the temperature sensor and humidity sensor inside the test chamber product are converted into electrical signals, which are amplified by the microcomputer controller to control the operation of the heater, refrigeration compressor, and humidifier, so as to achieve the required temperature and humidity.

[0003] When the existing test chamber is in use, the product support plate inside it is usually installed by clamping, and it cannot slide after installation, resulting in the need for the staff to reach into the test chamber to take the product, which may knock down the product during the process, and there is a certain degree of inconvenience.

[0004] Therefore, aiming at the problem that the product support plate of the existing test chamber cannot slide during use and it is not convenient for the staff to take the test product, an expandable test chamber with convenient product loading and unloading can be designed. By setting a sliding groove, the support plate can slide inside the sliding groove, so that the staff can easily pull out the support plate outward, achieving the purpose of facilitating the loading and unloading of products and avoiding the support plate slipping out of the sliding groove and causing the upper products to fall. Summary of the Utility Model
