Description
Technical field
The utility model relates to waveguide technical field of sealing technology, particularly relates to a kind of waveguide black box.
Background technology
Not only the effect of waveguide sealing is in order to make electromagnetic wave transmit but also the air-flow that can seal in waveguide or liquid high permeability, be mainly used in the ventilation orifice place of plumbing, EMI (Electro-Magnetic Interference, electromagnetic interference) shielding can be realized and ventilate.
At present, conventional waveguide hermetically-sealed construction is generally offer mounting groove on flange, is fixed in mounting groove by the dieelctric sheet of sealing.But because mounting groove offered by needs, so the structural design of flange is comparatively complicated, and dieelctric sheet must mate completely with mounting groove, or even interference fit, otherwise easily occur loosening, affect sealing.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of waveguide black box, can simplify the structure of flange, and fast and easy is installed.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of waveguide black box, described waveguide black box comprises first wave guide, second waveguide, first flange, second flange and medium diaphragm, one end of first wave guide described in described first flange connect, one end of second waveguide described in described second flange connect, the edge of the end face of described first flange is protruding with stage portion, described stage portion encloses annular space at the end face of described first flange, the edge of the end face of described second flange caves inward forming station terrace, described stage portion matches with described step surface, and the degree of depth of described step surface is greater than the width of described stage portion, described medium diaphragm is located on the end face of described first flange, and be positioned at described annular space, the end face of described first flange and the end face of described second flange paste merga pass securing member and are fastenedly connected.
Preferably, described securing member is bolt assembly.
Preferably, the size of described medium diaphragm and described annular space adaptation, and the edge of described medium diaphragm is against described stage portion.
The beneficial effects of the utility model are: the situation being different from prior art, waveguide black box of the present utility model is by arranging stage portion and step surface respectively at the edge of the end face of two flanges, medium diaphragm is placed in the annular space that stage portion encloses, owing to not needing that again flange arranges mounting groove, thus the structure of flange can be simplified, fast and easy is installed.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model waveguide black box embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, 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 belong to the scope of the utility model protection.
See Fig. 1, it is the schematic diagram of the utility model waveguide black box embodiment.The waveguide black box of the utility model embodiment comprises first wave guide 1, second waveguide 2, first flange 3, second flange 4 and medium diaphragm 5, first flange 3 connects one end of first wave guide 1, second flange 4 connects one end of the second waveguide 2, the edge of the first flange 3 end face is protruding with stage portion 31, stage portion 31 encloses annular space 32 at the end face of the first flange 3, the edge of the end face of the second flange 4 caves inward forming station terrace 41, stage portion 31 matches with step surface 41, and the degree of depth L2 of step surface 41 is greater than the width L1 of stage portion 31, medium diaphragm 5 is located on the end face of the first flange 3, and be positioned at annular space 32, the end face of the first flange 3 and the end face of the second flange 4 paste merga pass securing member 6 and are fastenedly connected.
Specifically, stage portion 31 is annular on the end face of the first flange 3, and annular space 32 is also annular.Preferably, the size of medium diaphragm 5 and annular space 32 adaptation, and the edge of medium diaphragm 5 is against stage portion 31.That is, the diameter of medium diaphragm 5 at least with the equal diameters of annular space 32.Further, the diameter of medium diaphragm 5 can be a bit larger tham the diameter of annular space 32, makes medium diaphragm 5 and stage portion 31 form interference fit.After medium diaphragm 5 is placed in annular space 32, by securing member 6 first flange 3 and the second flange 4 be fastenedly connected and form a whole, in fastener cycle, first flange 3 and the second flange 4 compress medium diaphragm 5 gradually, thus ensure that medium diaphragm 5 reliably seals first wave guide 1 and the second waveguide 2.Alternatively, securing member 6 is bolt assembly.Further, bolt assembly is multiple, and evenly in the edge circle distribution of the first flange 3 and the second flange 4.Medium diaphragm 5 can be teflon plate.
By the way, the waveguide black box of the utility model embodiment is cooperatively interacted by the step surface in the stage portion on the first flange 3 and the second flange 4, when fastening first flange 3 and the second flange 4, medium diaphragm 5 completes the sealing to first wave guide 1 and the second waveguide 2, whole waveguide path is made to have highly reliable sealing property and signal stabilization transmission performance, and owing to not needing to offer mounting groove, the processing technology of flange is simple, thus the structure of flange can be simplified, fast and easy is installed.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
