The invention relates to a communication machine room with good anti-theft performance and the waterproof function. The communication machine room comprises a main body and a door plate, and further comprises an anti-theft mechanism and a waterproof mechanism; the anti-theft mechanism comprises an identification assembly and an unlocking assembly; and the waterproof mechanism comprises an air cylinder, a pushing block, a telescopic frame, a sliding block, a lifting plate and a supporting table. In the communication machine room with the good anti-theft performance and the waterproof function,through the anti-theft mechanism, unlocking and door opening can be conducted after face identification and screening, the locking effect of the door plate is good, and the door plate is hard to damage manually due to the fact that two clamping blocks are arranged in the door plate; in addition, the door plate is locked simultaneously through the two clamping blocks, so that the anti-theft performance is further improved, and the situation that people who have an ulterior motive damage and steal important communication equipment inside the communication machine room is avoided; and through thewaterproof mechanism, an air conditioner outdoor unit can be raised, the situation that the air conditioner outdoor unit is immersed by accumulated water is avoided, the situation that an air conditioner is damaged and consequently adjustment of the temperature and humidity inside the machine room is affected is prevented, and the practicality of the machine room is greatly improved.
