Problems solved by technology

But between the door leaf and the doorframe of existing airtight door, owing to be to cooperate and seal by door sill and sealing strip, when airtight door is in closed state, generally all can have certain gap, thereby influence the sealing effect of airtight door; There will be more dirt and dust entering the threshold, which will also affect the sealing performance of the airtight door
At the same time, the sealing strips on the existing airtight doors are generally installed on the door leaf by sections first, and then the adjacent sealing strips are overlapped. After a long time of use, the sealing performance between the adjacent sealing strips will decrease. , which affects the overall airtight performance of the airtight door; since the sealing strip is fixed on the door leaf in sections, adjacent sealing strips are prone to uneven compression when under pressure, which seriously affects the sealing effect
Therefore, the existing airtight door has the problem of unsatisfactory airtight effect

Abstract

The invention discloses a lifting horizontal-moving-type air-tight door which comprises a door frame (1) and a door leaf (2). An annularly-formed sealing clamping groove (3) is formed in the outer edge surface of the door leaf (2) and is internally provided with an integral-type sealing strip; two hinge mechanisms (5) which are vertically symmetrically arranged are arranged on the side surface ofthe door leaf (2), and a lifting mechanism (6) which is fixed to the door frame (1) is arranged above the hinge mechanism (5) at the lower end; and side surface horizontal moving mechanisms (7) are arranged on the two sides of the door leaf (2), and an upper horizontal moving mechanism (8) is arranged above the door leaf (2). The lifting horizontal-moving-type air-tight door has the characteristicthat the air-tight effect of the air-tight door can be improved.

Description

technical field [0001] The invention relates to a protective door, in particular to a lifting and translation type airtight door. Background technique [0002] In civil air defense projects, airtight doors are required to prevent and resist disasters. But between the door leaf and the doorframe of existing airtight door, owing to be to cooperate and seal by door sill and sealing strip, when airtight door is in closed state, generally all can have certain gap, thereby influence the sealing effect of airtight door; There will be more dirt and dust entering the threshold, which will also affect the sealing performance of the airtight door. At the same time, the sealing strips on the existing airtight doors are generally installed on the door leaf by sections first, and then the adjacent sealing strips are overlapped. After a long time of use, the sealing performance between the adjacent sealing strips will decrease. , affecting the overall sealing performance of the airtight ...
