DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] The present utility model provides as Figures 1-3An antenna waveguide sealing device shown in the figure comprises a first waveguide tube 1 and a second waveguide tube 2. A connecting plate 3 is provided at the port of the first waveguide tube 1, and a sealing groove 4 is provided on the connecting plate 3. A mounting plate 5 is provided on the second waveguide tube 2, and a sealing block 6 is provided on the mounting plate 5. The sealing block 6 is matched with the sealing groove 4 in a concave-convex manner. A gasket 7 is provided on the connecting plate 3, and the gasket 7 is located on the inner side of the sealing groove 4. A protrusion 8 is provided on the mounting plate 5, and one end of the protrusion 8 is movably connected to the gasket 7. The gasket 7 is composed of two spherical blocks 9 and a supporting block 10 connected thereto, and the diameters of the two spherical blocks 9 decrease from the outside to the inside. One end of the protrusion 8 is movably connected to the outer wall of the supporting block 10, and the outer walls of the adjacent two sides thereof are in contact with the two spherical blocks 9 respectively. When connecting the first waveguide 1 and the second waveguide 2, the connecting plate 3 is docked with the mounting plate 5 in the horizontal direction, so that the sealing block 6 is inserted into the sealing groove 4 to achieve concave-convex matching. While the two are in contact with each other and connected, one end of the protrusion 8 also matches with the outer wall of the gasket 7 to achieve connection. The protrusion 8 is connected to the support block 10 set in the middle of the gasket 7, and in the subsequent fixation, the distance between the connecting plate 3 and the mounting plate 5 is gradually reduced through the connection between the fixing bolts 12 and the nuts 13, so that the two spherical blocks 9 on the gasket 7 are gradually deformed, and the protrusion 8 is tightly connected with the support block 10. Sealing is achieved through the cooperation between the sealing block 6 of the outer ring and the sealing groove 4, and between the inner ring protrusion 8 and the gasket 7. The operation is simple, the workload is reduced, and the maintenance operation is convenient. The sealing groove 4 and the gasket 7 are both rectangular and made of rubber. The two spherical blocks 9 of the gasket 7 are hemispherical, with a larger outside and a smaller inside. After the protrusion 8 is connected, the spherical block 9 on the outside can touch and squeeze the mounting plate 5, and the contact area can be increased by deformation. The internal spherical block 9 is smaller, and the gap between the outer walls on the opposite sides of the protrusion 8 can be reduced by deformation of the spherical blocks 9 on the inner and outer sides, thereby ensuring the sealing effect.

[0020] Specifically, the connecting plate 3 and the mounting plate 5 are both provided with an extension block 11, and the extension block 11 is provided with a fixing bolt 12. The extension block 11 is provided with a mounting hole 14, one end of the fixing bolt 12 extends to the outside of the mounting hole 14, and a nut 13 is threadedly connected to the outer wall of the extension block 11. The nut 13 is movably connected to the outer wall of one side of the extension block 11. Figure 2 , 3As shown, the fixing bolts 12 respectively penetrate through the mounting holes 14, and the nuts 13 are threadedly connected to the outer walls of the fixing bolts 12. By adjusting the connection between the nuts 13 and the fixing bolts 12, the distance between the connecting plate 3 and the mounting plate 5 is gradually reduced. And the sealing block 6 and the sealing groove 4, the convex block 8 and the washer 7 are in close contact when the distance between the connecting plate 3 and the mounting plate 5 is gradually approaching. Through the cooperation of the inner ring and the outer ring, the tight connection between the first waveguide 1 and the second waveguide 2 is realized. And there are several extension blocks, and the fixing bolts and nuts can be adjusted according to the actual situation to achieve the best use effect; wherein a waveguide medium is provided on the inner wall of the end of the first waveguide 1 where the connecting plate 3 is arranged for use.

[0021] Working principle: Horizontally butt the first waveguide 1 and the second waveguide 2 in the similar direction respectively, so that the sealing block 6 is inserted into the sealing groove 4. Protrusions are provided on the outer walls of the opposite sides of the sealing block 6. Under the action of a certain force, the sealing block 6 is installed into the sealing groove 4. The basic sealing and fixing are realized through the cooperation of the protrusions and the sealing groove 4, so as to facilitate the subsequent fixing work. After connection through the cooperation of the fixing bolts 12 and the nuts 13, through the cooperation of the sealing block 6 and the sealing groove 4 on the outer ring and the cooperation of the convex block 8 and the washer 7 on the inner ring, the tight connection between the first waveguide 1 and the second waveguide 2 is realized, which is simple and convenient and beneficial to use.
