High and low temperature damp heat test box

Abstract

The invention discloses a high and low temperature damp heat test box. The test box comprises a box body; mounting mechanisms are symmetrically arranged in the box body; placing plates are arranged in the mounting mechanisms; a plurality of heaters are fixedly connected to the inner side wall of the box body; a plurality of refrigerators are fixedly connected to the inner side wall of the box body on one side of the plurality of heaters; and mounting shells are symmetrically and fixedly connected to the bottom of the box body. According to the test box, the placing plates can be inserted into the openings of mounting blocks and driven by electric push rods to be quickly mounted and dismounted, products at different heights can be detected, the application range of the test box is widened, the operation process is more convenient, time-saving and labor-saving, the working efficiency is improved, and the practicability is higher.

Description

technical field [0001] The invention relates to the technical field of test chambers, in particular to a high and low temperature damp heat test chamber.

Problems solved by technology

[0003] Most of the existing high and low temperature humidity test chambers are equipped with moving wheels for easy movement, but most of them do not have the effect of shock absorption. Vibration will cause damage to the electronic devices inside the high and low temperature humidity test chamber, which will affect the service life of the device. During the testing process, the test chamber is often in a closed state, and usually the interior does not have the effect of fire prevention. Once there is a safety hazard , will cause damage to the internal electronic devices. At the same time, because the support plate inside the high and low temperature humidity test chamber is usually fixed connection or fixed by screws, when it is necessary to detect products of different heights, the height of the support plate cannot be adjusted. Moreover, the process of disassembly and installation is relatively cumbersome, and the practicability is poor, which cannot meet the needs of users. In order to solve this problem, a high and low temperature damp heat test chamber is proposed.
