Concrete sealingdoor with sealing device

Abstract

The invention discloses a concrete sealing door with a sealing device. The key points of the technical scheme of the concrete sealing door with the sealing deviceare that the concrete sealing door with the sealing device comprises a door body, a door frame, and a sealing mechanism arranged on the four sides of the door frame;the sealing mechanism comprises an upper and lower sealing mechanism, a left and right sealing mechanism, a driving mechanism,and a retracting mechanism, a first sealing groove with length being consistent with the width of the door body is formed in the upper and lower side surfaces of the door body respectively, a second sealing groove with length being consistent with the height of the door body is formed inthe left and right side surfaces of the door body respectively, the upper and lower sealing mechanisms are matched with the corresponding first sealing grooves in a sealing moderespectively, the left and right sealing mechanisms are matched with the corresponding second sealing grooves in a sealing moderespectively, the driving mechanism is in through connection with a high pressure gas pipe, and the retracting mechanism is arranged in each ofsliding moving grooves. According to the concrete sealing door with the sealing device, sealing between the concrete door body and a door frame gap can be improved, so that the using effect of the concrete door and the sealing level of a protection space are improved.

Description

technical field [0001] The invention relates to a concrete protective door, more specifically, it relates to a concrete airtight door with a sealing device. Background technique [0002] In some protection projects, due to the special environmental requirements, the protection space needs to be sealed, but the current concrete door sacrifices some of the sealing requirements around the door body in order to maintain operability, so that in the actual application process, the concrete door After the body is closed, the sealing performance of the protection level cannot be achieved. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a concrete airtight door with a sealing device that can adjust the sealing of the space and improve the sealing effect of the space. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a concrete airtight d...
