Automatically-protected electric control voltage transformation case of intelligent manufacturing amusement equipment

The invention provides an automatically-protected electric control voltage transformation case of intelligent manufacturing amusement equipment. A mounting block is arranged in the middle of the bottom end in a cabinet body, water tanks are arranged at the positions, located on the two sides of the mounting block, of the bottom end in the cabinet body, and rubber rings are installed on the inner walls of the left side and the right side of the cabinet body; an electric appliance element cabinet is installed in the middle of the interior of the cabinet body, and threaded rods are installed at the positions, located in front of and behind the electric appliance element cabinet, of the interior of the cabinet body. When the external temperature rises, mercury in the connecting column and thetelescopic rod expands, the telescopic rod is pushed to expand the rubber ring outwards, the circulation area of air is increased, when rainwater or water vapor is attached to the surface of the baffle and gradually accumulat
