an airtight door

Abstract

The invention discloses an airtight door, which comprises a wall body, a door frame is fixedly installed inside the wall body through expansion bolts, a door body is hinged inside the door frame through pin rods, and a metal Frame, the four corners of the back of the door are provided with limiting slots, and the back of the door is provided with a sealing plate. In the present invention, the arc-shaped sealing sleeve can seal the gap between the door frame and the door body through its own elastic force, and then the magnet ring drives the rubber sleeve to be pressed tightly on the surface of the metal frame through the limit mechanism, so that the rubber sleeve can pass through the magnet ring and the door body. The sealing plate performs secondary sealing on the gap between the door body and the door frame, which has the advantage of better air tightness, and solves the problem that the existing door is only sealed by a single sealing ring after closing, and the sealing effect is poor, resulting in the door The heat in the interior is easy to lose quickly due to the gaps, and at the same time, the dust is easy to enter the room through the gaps, which is convenient for people to use.

Description

technical field [0001] The invention relates to the technical field of door structures, in particular to an airtight door. Background technique [0002] A door, the entrance of a building or a device that can be opened and closed at the entrance, is an entity that divides a limited space, and can connect and block the entrances and exits of two or more spaces. [0003] Doors are divided into enclosure members or partition members according to their positions, but the existing doors are only sealed by a single sealing ring after closing, and the sealing effect is poor, which leads to the rapid loss of heat in the door due to gaps. Simultaneously, the phenomenon that dust easily enters the room through the gap is not convenient for people to use. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention provides an airtight door, which has the advantages of better airtightness, and solves th...
