Through the cooperation of the ventilation pipes 7, ventilation holes 5 and empty shell 6, the air circulation between the inside of the constant temperature and humidity test chamber body 1 and the outside is realized, thereby realizing heat dissipation. An activity frame 9 is movably installed outside the empty shell 6, and a dust-proof net 13 is fixedly installed in the inner cavity of the activity frame 9.

[0023] Please refer to Figure 3 and Figure 4, The connecting mechanism includes four round tubes 14 which are arranged in a rectangular distribution, and all four round tubes 14 are fixedly connected to the outer wall of the constant temperature and humidity test chamber body 1. A spring 15 is arranged in the inner cavity of the round tube 14. One end of the spring 15 is fixedly connected to the outer wall of the constant temperature and humidity test chamber body 1, and the other end of the spring 15 is fixedly connected to a round rod 16.

During the ventilation and heat dissipation period, the setting of multiple dust-proof nets 13 can prevent external dust from entering the inside of the constant temperature and humidity test chamber body 1 along the ventilation pipe 7 and affecting the heat dissipation effect of the internal electronic components. After working for a period of time, the threaded connection between the threaded block 18 and the threaded sleeve 17 can be released to realize the disassembly between the movable frame 9 and the empty shell 6, and further realize the disassembly of the dust-proof net 13, so that the dust-proof net 13 can be cleaned. Subsequently, the threaded block 18 and the threaded sleeve 17 are used for installation, and the operation is convenient. When the constant temperature and humidity test chamber body 1 is transported, the rubber pads 12 on the outer sides of the multiple movable frames 9, the movable frames 9 and the empty shell 6 separate the constant temperature and humidity test chamber body 1, and the setting of multiple groups of springs 15 can play a buffering effect between two adjacent constant temperature and humidity test chamber bodies 1 to avoid collision and play a protective effect.
