It is a place for processing and storing agricultural and livestock products. According to incomplete statistics from relevant departments, the total annual output of various fresh products in my country is about 700 million tons, the annual output of frozen food is more than 25 million tons, and the total output value is more than 52 billion yuan; there are about 20,000 food freezing and refrigeration companies with an annual turnover of more than 5 million yuan (including 5 million) (including cold storage workshops and cold storages in processing companies), 2.5 million employees, and the national cold storage capacity is about 9 million tons. There is an existing patent for a swing cold storage door, patent publication number CN112878815A, which includes a door frame and a door body. The door body is provided with a locking piece, and the door frame is provided with an emergency mechanism corresponding to the locking piece. The locking piece includes a fixed A lock shell in the door body, a lock pin slidably arranged in the lock shell, a movable pin connected to the lock pin, a locking piece arranged on the movable pin for locking the movable pin on the lock pin, and an unlocking piece slidably arranged in the lock shell. When the lock pin is locked on the door body and the movable pin is locked on the lock pin, the movable pin can be inserted on the door frame to lock the door body.
