Three-point locking safety door lock for pressure steamer

Abstract

The invention provides a three-point locking type safety door lock for a pressure steamer, which is composed of a lock box, a main bolt, a handle, an upper bolt, a lower bolt, a rotating shaft, a connecting rod, a connecting rod seat, and a connecting rod pin. There is a safety mechanism in the buckle box, and the lower end hole of the cylinder head communicates with the inside of the steamer through a steam pipe. The lock box is installed on the door frame of the steaming cabinet, and other components are installed on the door of the steaming cabinet through the rotating shaft. After closing the door, turn the handle, the lock tongue enters the lock box, the upper and lower lock tongues respectively enter the lock tongue holes of the upper and lower door frames, and the steamer door is locked. When the pressure in the steamer rises, the steam pushes the ejector rod, and the ejector rod pushes the safety buckle to lock the main bolt, and the door of the steamer cannot be opened. When the pressure in the steaming cabinet drops to the safe pressure, the ejector rod and the safety buckle fall off under the action of gravity, and the door of the steaming cabinet can be opened by turning the handle.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, in particular to a door lock of a pressure steamer. Background technique [0002] The door lock of the steaming cabinet generally adopts a one-point locking method, that is, a deadbolt is inserted into the buckle; The door is deformed, the seal of the steaming cabinet is destroyed, and air leakage occurs; some steaming cabinets are locked at multiple points, and each point is generally locked separately, which is inconvenient to operate. [0003] There is often pressurized high-temperature steam in the steamer. If the door of the steamer is opened in this case, this high-temperature steam will be sprayed out, which may burn people and pose a safety hazard. The current steam cabinet door locks usually do not have a safety protection device. When there is pressure in the steam cabinet, the door lock is easy to open, and there are unsafe factors.
