Compression and heat resistant gear-connected bar type sealing door

Abstract

The invention relates to a compression and heat resistant gear-connected bar type sealing door. The compression and heat resistant gear-connected bar type sealing door comprises a door frame, a door body, a hand wheel shaft, a hand wheel, a driving gear, driven gears, hexagon nuts, connecting rods I, guiding grooves, connecting rods II and a hinge. The door body is of a circular structure and slightly protruded in the middle, the door frame is of a ring-shaped structure, and the door frame and the door body are used in a matched mode; notches are formed in the periphery of the door body, high temperature resistant adhesive tapes are installed in the notches, so that the airtightness of the overall device is ensured, and invasion of toxic and harmful gas is prevented. According to the compression and heat resistant gear-connected bar type sealing door, the flat ends of the connecting rods II are driven to enter the door frame through movement of a gear-connected bar mechanism; with increasing of the entered flat ends of the connecting rods II, the sealing door is locked tightly, meanwhile, the self-lock function is achieved through profile connection; and the compression and heat resistant gear-connected bar type sealing door has the obvious advantages that operation is convenient, the structure is simple, the effects of compression and heat resistance, safety and reliability are achieved, and airtightness is good.

Description

technical field [0001] The invention relates to a hermetic door, in particular to a pressure-resistant and heat-resistant gear link type hermetic door. Background technique [0002] Various airtight doors are used in human life and work, and the application range of airtight doors is getting wider and wider. Airtight doors are mainly used to prevent direct convection between the isolated space and the outside air, and form a certain airtight space in the isolated space. Negative pressure to reduce the pollution of the partitioned space to the outside world and ensure that the passage is not affected by heat waves. There are various airtight doors on the market, such as: fireproof airtight door, thermal insulation airtight door and pressure-resistant airtight door, etc., but these airtight doors have many problems such as complex structure, poor reliability, poor adaptability, and single function. In view of the many disadvantages of the above-mentioned sealed door, the pres...
