Abstract
The utility model provides a unidirectional airtight door which comprises a door panel and a doorframe, wherein the door panel is filled in the doorframe; and the unidirectional airtight door is characterized in that a seal groove is arranged at the outer side of the periphery of the doorframe, an inflation seal ring is installed in the seal groove, and a sliding block is respectively and fixedly arranged at each of the upper and the lower ends of the doorframe. Through arranging the inflation seal ring in the seal groove at the periphery of the doorframe to realize sealing, compared with the traditional seal mode, the unidirectional airtight door has better sealing performance. Moreover, the upper and the lower ends of the doorframe are respectively provided with the sliding block, the sliding blocks are matched with guide rails which are installed at the upper and lower ends of the doorframe, so the unidirectional airtight door can be opened and closed. The working mode enables the unidirectional airtight door to be conveniently opened, and the automatic control of the unidirectional airtight door is easy to realize.
Description
Technical field
The utility model relates to a kind of hermatic door body.
Background technology
In many equipment that need sealed environment, all be provided with the hermatic door body; Existing hermatic door body generally all adopts door body inner plane edge and is arranged between the rubber seal on the body plane and pushes and realize sealing; But this mode can make door lock stressed big; It is heavier to open the door, and sealing effectiveness is bad.
Summary of the invention
The utility model is to the deficiency of above-mentioned prior art, a kind of good seal performance is provided, opened lightly, and realizes the one-way sealing door body of control automatically easily.
The utility model is realized through following technical scheme:
A kind of one-way sealing door body comprises door-plate and door body framework, and door-plate is filled in the body framework; It is characterized in that arranged outside has seal groove around the door body framework, and the gas-flow closure circle is installed in the seal groove, the two ends up and down of door body framework all are set with slide block.
Further, the two ends up and down of door body framework all are set with at least two slide blocks.
Further, said slide block all is installed on the body framework through the slide block installing plate.
Further, said gas-flow closure circle adopts silastic material to process.
Further, said door-plate is provided with many reinforcing ribs.
Further, all adopt round-corner transition for four angles of said door body framework.
The described one-way sealing door of the utility model body is realized sealing through the gas-flow closure circle is set in the seal groove around the door body framework, compare with the conventional seals mode, and its sealing performance is better.Simultaneously the utility model is provided with slide block at the two ends up and down of door body framework, slide block be installed in a body framework about the guide rail at two ends cooperate, can realize opening and closing of this one-way sealing door body.It is light that this kind working method makes this one-way sealing door body open, and realize the automatic control of one-way sealing door body easily.
Description of drawings
Fig. 1 is the front view of the described one-way sealing door of the utility model body;
Fig. 2 is an A-A profile among Fig. 1;
The implication of each label is following among the figure:
Slide block installing plate-1, fillet-2, reinforcing rib-3, door-plate-4, door body framework-5.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Shown in Fig. 1-3, the utility model provides a kind of one-way sealing door body, comprises door-plate 4 and door body framework 5, and door-plate 4 is filled in the body framework 5.Arranged outside has seal groove around the door body framework 5, and the gas-flow closure circle is installed in the seal groove, and the gas-flow closure circle adopts silastic material to process.The upper/lower terminal of door body framework 5 all is set with slide block, and said slide block is at least two.Each slide block all is installed on the body framework 5 through a slide block installing plate 1.Slide block cooperates with two guide rails that are installed in a upper/lower terminal of body framework 5, can realize opening and closing of this one-way sealing door body.After one-way sealing door body is closed, open the source of the gas control end of gas-flow closure circle, be the inflation of gas-flow closure circle, its sealed working face outwards protrudes, and realizes sealing.After one-way sealing door body is opened, close the source of the gas control end of gas-flow closure circle, the venting of gas-flow closure circle, depressurization.
In order to increase the soundness of said one-way sealing door body, also be provided with many reinforcing ribs 3 on the door-plate 4, reinforcing rib 3 is supported by door body framework 5.
In order to adapt to the corner of gas-flow closure circle, fillet 2 transition are adopted at four angles of said door body framework 5.
The utility model not only is confined to the above-mentioned specific embodiment; Persons skilled in the art are according to the disclosed content of the utility model; Can adopt other multiple specific embodiment to implement the utility model, therefore, project organization of every employing the utility model and thinking; Do some simple designs that change or change, all fall into the scope of the utility model protection.
