Description

Technical Field

[0001] The utility model relates to the field of test boxes, in particular to a constant temperature and humidity test box. Background Art

[0002] Constant temperature and humidity test chamber is a device used to test the performance of materials in various environments. It can be used to test the heat resistance, cold resistance, dryness resistance and moisture resistance of various materials.

[0003] The existing patent with publication number CN 218339823 U provides a constant temperature and humidity test box, including a shell, a box body is fixedly connected to the top of the shell, a loading box is fixedly connected to the inside of the shell, a water tank is fixedly connected to the top of the loading box, a humidifier is fixedly connected to the top of the water tank, an air conditioner outdoor unit is fixedly connected to the top of the air conditioner outdoor unit, an air conditioner indoor unit is fixedly connected to the top of the air conditioner outdoor unit, and a first loading plate is arranged inside the box.

[0004] When the above patent is in use, the starting motor drives the second gear to rotate, and the rotation of the second gear drives the first gear to rotate. The two first gears rotate in the same direction. The rotation of the two second gears drives the two threaded rods to rotate. The rotation of the two threaded rods drives the two threaded blocks to move downward at the same time. The movement of the threaded blocks drives the sliding rod and the first loading plate to move downward, so that the distance between the first loading plate and the second loading plate can be adjusted, so that the effect of testing different sizes of notes can be achieved. However, through the operation of the motor and other structures, only the position of one loading plate can be adjusted. When multiple layers of objects need to be placed at the same time, it is difficult to adjust the spacing of multiple loading plates through the threaded rods, which is not flexible enough to use.
