Abstract
The utility model relates to an automatic pressing mechanism for a drying box door on a freezing dryer, which is characterized in that the upper end and the lower end of a frame of a cylinder are respectively fixed with a socket sleeve of the gas cylinder and a bolt gas cylinder by screws; a rod of the bolt cylinder is connected with a rotary extensible bolt. One end of a rotary handle is connected with the lower end of the extensible bolt by a self-lubricating bearing, and the other end is connected with a locking cylinder. The locking cylinder is arranged on an installing frame of the locking cylinder, and is fixed with the frame of a drying box body by the screws. A pressing block is arranged on the upper end of the extensible bolt by a pressing bolt and the self-lubricating bearing. The socket sleeve of the cylinder is arranged outside the extensible bolt, an O-shaped sealing ring and a self-lubricating belt are arranged between the socket sleeve of the cylinder and the extensible bolt, and another O-shaped sealing ring is arranged between the socket sleeve of the cylinder and the frame of the drying box door. The utility model has the advantage that the drying box door on the freezing dryer is conveniently closed without manual operation.
