Abstract
The utility model discloses a kind of closed guard gate's hermetically-sealed construction, comprise people's air defense doorframe, people's air defense door leaf, weather strip, pressing plate and screw, the outer wall of described people's air defense doorframe is provided with people's air defense door leaf, described people's air defense doorframe is directly located by weather strip mutually with described door leaf, described weather strip is a convex shape, and centre is hollow, and described weather strip two ends are equipped with pressing plate, pressing plate described in every block is equipped with screw, by described screw, described weather strip is fixed on people's air defense doorframe.The utility model is simple and reasonable, is directly carried out the location of people's air defense doorframe and people's air defense door leaf by weather strip, and has carried out unique design to weather strip, and in a convex shape, so just do not need to arrange seal groove on people's air defense doorframe, easy to operate, cost is low; Moreover owing to being hollow in the middle of weather strip, and the whole circle of weather strip does not all have seam, increases the contact surface area of laminating, enhances sealing performance.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction, specifically a kind of closed guard gate's hermetically-sealed construction, belongs to civil air defense projects safeguard production mounting technique field.
Background technology
Due to the particularity of civil air defense projects, the sealing performance of the safeguard adopted as closed guard gate is most important, and the closed guard gate's hermetically-sealed construction relative complex in currently available technology, and sealing intensity is not high, easily produces dead angle, thus cause leakage phenomenon to occur.A kind of protective door sealed door of large tunnel civil air defense constructions and installations disclosed in Chinese patent CN201020640607.3, comprise door leaf, doorframe, hinge mechanism, blocking mechanism, resetting-mechanism, wicket and trench cover plate, not only complex structure, and poor sealing performance, affect personal safety; And for example high closed loop structure disclosed in Chinese patent CN201220138775.1, although it is relatively convenient to operate, sealing is relatively better, but this structure is also provided with seal groove, moreover weather strip is solid, the contact surface area of laminating is just little, and weather strip exists seam, so the simple degree of its structure and sealing performance still have much room for improvement.
Utility model content
For the problems referred to above, the problem that the utility model quasi-solution is determined is to provide simple, the easy to operate and closed guard gate's hermetically-sealed construction that sealing performance is strong of a kind of structure.
For achieving the above object, the utility model is by the following technical solutions: a kind of closed guard gate's hermetically-sealed construction, comprise people's air defense doorframe, people's air defense door leaf, weather strip, pressing plate and screw, the outer wall of described people's air defense doorframe is provided with people's air defense door leaf, described people's air defense doorframe is directly located by weather strip mutually with described door leaf, described weather strip is a convex shape, and centre is hollow, described weather strip two ends are equipped with pressing plate, pressing plate described in every block is equipped with screw, by described screw, described weather strip is fixed on people's air defense doorframe.
As preferably, the shape of cross section of described weather strip central hollow section is circular.
The beneficial effects of the utility model: the utility model is simple and reasonable, directly carry out the location of people's air defense doorframe and people's air defense door leaf by weather strip, and have carried out unique design to weather strip, in a convex shape, so just do not need to arrange seal groove on people's air defense doorframe, easy to operate, cost is low; Moreover owing to being hollow in the middle of weather strip, and the whole circle of weather strip does not all have seam, increases the contact surface area of laminating, enhances sealing performance.When people's air defense door leaf cuts out, be pressed on the high spot of weather strip, because weather strip has deformation behavior, thus make closed guard gate airtight.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1-people's air defense doorframe, 2-people's air defense door leaf, 3-weather strip, 4-pressing plate, 5-screw.
Detailed description of the invention
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the present embodiment, clear, complete description is carried out to the technical scheme in the utility model embodiment.
As shown in Figure 1, the utility model discloses a kind of closed guard gate's hermetically-sealed construction, comprise people's air defense doorframe 1, people's air defense door leaf 2, weather strip 3, pressing plate 4 and screw 5, the outer wall of described people's air defense doorframe 1 is provided with people's air defense door leaf 2, described people's air defense doorframe 1 and described door leaf 2 are directly located by weather strip 3 phase, described weather strip 3 is in a convex shape, and centre is hollow, described weather strip 3 two ends are equipped with pressing plate 4, pressing plate 4 described in every block is equipped with screw 5, by described screw 5, described weather strip 3 is fixed on people's air defense doorframe 1, the shape of cross section of described weather strip 3 central hollow section is circular.
The utility model is simple and reasonable, is directly carried out the location of people's air defense doorframe 1 and people's air defense door leaf 2 by weather strip 3, and has carried out unique design to weather strip 3, in a convex shape, so just do not need to arrange seal groove on people's air defense doorframe 1, easy to operate, cost is low; Moreover owing to being hollow in the middle of weather strip 3, and the whole circle of weather strip 3 does not all have seam, increases the contact surface area of laminating, enhances sealing performance.When people's air defense door leaf 2 cuts out, be pressed on the high spot of weather strip 3, because weather strip 3 has deformation behavior, thus make closed guard gate airtight.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
