Abstract
The patent of the utility model relates to a circuit structure, in particular to a high-tightness circuit structure, which is applied in civil air defense works. The high-tightness circuit structure comprises a door frame, the outer wall of the door frame is provided with a door leaf, the door frame and the door leaf are positioned by a bearing plate, the inner side of the bearing plate is provided with a sealed circuit, an embedded bar is arranged in the sealed circuit, and the bottom of the embedded bar is fixedly connected with the door leaf. The high-tightness circuit structure is simple and can be operated conveniently, and the tightness and the personal safety can be improved.
Description
Technical field
The utility model patent relates to a kind of loop structure structure, relates in particular to a kind of high closed loop structure, is used for civil air defense constructions and installations.
Background technology
Sealing system in the present sealed door of the prior art, the structure relative complex, and also airtight intensity is not high, is easy to generate the dead angle, thus cause poison gas to get into engineering inside.
Chinese patent CN201020640607.3 discloses the airtight blast door that a kind of large tunnel civil air defense constructions and installations is used.Comprise door leaf, doorframe, hinge mechanism, blocking mechanism, resetting-mechanism, wicket, trench cover plate.Airtight performance is poor, influences personal safety.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the prior art, provides a kind of simple in structure, and airtight performance is high, improves the high closed loop structure of safety factor.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of high closed loop structure comprises doorframe, and the outer wall of described doorframe is provided with door leaf; Locate mutually through bearing plate between described doorframe and door leaf; The inboard of described bearing plate is provided with sealed circuit, is provided with embedded pressing bar in the described sealed circuit, and the bottom and the door leaf of described embedded pressing bar fix.
Adopt sealed circuit, when door leaf was closed, weather strip compressed simultaneously around the door leaf, does not produce the dead angle, stoped poison gas to get into the inside of engineering fully.
As preferably, the material of described sealed circuit is a sponge rubber.
As preferably, the bottom width in described sealed circuit cross section is 12mm.
Therefore, the high closed loop structure of the utility model, simple in structure, easy to operate, improve seal, improve personal safety.
Description of drawings
Fig. 1 is the structural representation of the utility model.
