[0002] A cold storage door is a door installed in cold storage equipment, freezer rooms, and other refrigerated environments to insulate and seal. An existing patent for an automatic cold storage door, patent publication number CN206556342U, includes a door frame and a sliding door. The door frame has a slide groove at the bottom, within which the sliding door can slide. A slide rail is located at the top of the door frame, and a pulley is provided on the sliding door that can roll within the slide rail. A motor and a fixed pulley are located at the top of the door frame. A pulley is mounted on the motor shaft, and a transmission belt is provided on the slide rail, connected to the pulley and fixed pulley. The pulley is fixed to the transmission belt. A switch device for turning the motor on and off is provided on one side of the door frame. When the operator needs to open the cold storage, they press a switch on one side of the door frame to start the motor. Once the motor starts, the pulley is driven by the transmission belt to accurately slide the sliding door from the door frame to one side, opening the cold storage. When the operator needs to close the cold storage, they simply press the switch again, allowing them to easily and conveniently open and close the cold storage.
