Rainproof airtight door device

Abstract

The invention discloses a rainproof airtight door device which mainly comprises a diversion trench door frame, a turnup-edge door, sealing pads and small holes. The rainproof airtight door device is characterized in that the door frame is in a shape as specified in the specifications, and a diversion trench structure is formed in the diversion trench door frame through bending; the turnup-edge door is in a shape as specified in the specifications, the turnup edge of the diversion trench door frame and the inner side of the turnup-edge door compress the sealing pads inwards, and the turnup edge of the turnup-edge door and the inner side of the diversion trench door frame compress the sealing pads inwards, so that a double-layer sealing structure is formed; and the small holes are formed in the portion, on the lower portion of the turnup-edge door, of the edge of the turnup-edge door. The rainproof airtight door device has the advantages that a simple combined structure is utilized, and the demand of protecting the device against rainwater is met; and the device is low in machining precision, efficient in rainproof performance, and capable of being integrated with carriers such as a building and a shelter during installation, free of occupying the indoor space, and meanwhile, maintenance is extremely easy and convenient. By adoption of the rainproof airtight door device, the production cost is lowered, the space utility rate is increased, efficient rain prevention is achieved, the production efficiency is improved, and the rainproof airtight door device has high social benefits and high economic benefits.

Description

technical field [0001] The invention relates to the field of airtight doors, in particular to a rainproof airtight door device. Background technique [0002] At present, in general industrial and civil buildings, shelters, box covers, etc., and equipment that may be exposed to rain, the door devices that need to be opened and closed frequently are installed in order to achieve rainproof sealing, and most of them adopt the structural form of "sealing" and "blocking". Due to processing and manufacturing errors, the flatness is not enough, and the close fit between the door and the door frame cannot be achieved during use, the effect of "sealing" and "blocking" cannot reach the ideal state, or the use of profiles with complex structures and occupying a large space, Or use sealant to seal, resulting in complex processing, cumbersome installation, occupying a large indoor area, and high maintenance costs. [0003] The invention utilizes a bending structure to form the door frame...
