Abstract
The utility model discloses an electromagnetic wave shielding door, belonging to shielding doors. The electromagnetic wave shielding door includes a floating gate made of metal and a metal doorframe mounted on the wall, four edges of the outer side of the metal doorframe are provided with U-shaped metal groove which is provided with a gasbag and an elevated inverse U-shaped elastic piece, one side of the inverse U-shaped elastic piece is fixed with one side of the metal groove. When filling gas into the gasbag, the inverse U-shaped elastic piece plumps up outward under the pressure of the gasbag and sticks to the floating gate tightly. Thus the electromagnetic wave enters a test room from a door gap. The advantage is that it is able to make a large-sized or a supersized shielding door, the open and the close of the door are all convenient, and the exterior electromagnetic wave is shielded from entering the test room with high efficiency; also the shielding door can be machined, produced and mounted at site.
Description
Technical field
The utility model relates to a kind of shield door, specifically is a kind of electromagnetic wave shield door.Mainly be applicable to the inside door and the external door of various bigger shield test reactor chambers.
Background technology
Present shield door mostly is the middle-size and small-size electromagnetic wave shield door of on-the-spot integral installation, and its structure is comparatively complicated, and cost of production is also high.So far do not appear in the newspapers for the 8m * 8m of special engineering special use and above large-scale and ultra-large type shield door.
Summary of the invention
The utility model provides a kind of electromagnetic wave shield door, is particularly suitable for making large-scale or superhuge shield door, opens the door and closes the door conveniently, can shield external electromagnetic wave expeditiously and enter test room inside.And can process at the scene, make, install.
The utility model is realized with following technical scheme: a kind of shield door, it comprises moving door of making of metal and the metal door frame that is installed on the body of wall, it is characterized in that U type metallic channel being installed on four limits in the metal door frame outside, the inverted U-shaped flexure strip that air bag is installed in U type metallic channel and can heaves, a side of inverted U-shaped flexure strip and a side of metallic channel are fixed together.After inflation in air bag, the moving door of being made by metal material just can outwards be heaved and be adjacent to inverted U-shaped flexure strip under the pressure of air bag.Thereby play the shielding electromagnetic wave enters test room from crack between a door and its frame effect.
The beneficial effects of the utility model are: can make large-scale or superhuge shield door, open the door and close the door conveniently, shield external electromagnetic wave expeditiously and enter test room inside.And can process at the scene, make, install.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, air bag, 2, inverted U-shaped flexure strip, 3, metallic channel, 4, moving door, 5, track, 6, construction wall, 7, metal door frame.
The specific embodiment
As shown in Figure 1, metal door frame 7 usefulness square steel pipes are made, be installed on the construction wall 6, on four limits in metal door frame 7 outsides U type metallic channel 3 is installed, air bag 1 and inverted U-shaped flexure strip 2 are installed in metallic channel 3, inverted U-shaped flexure strip 2 usefulness metal material are made, and a side of inverted U-shaped flexure strip 2 and a side of metallic channel 3 are fixed together with screw.The frame of moving door 4 is made of square steel pipe, does keel frame and filled heat insulating material in the door, and student side is equipped with track 5, can use motor-driven.
Shield door of the present utility model is applicable to the inside door and the external door of various bigger shield test reactor chambers.
