Description

Technical Field

[0001] The utility model relates to the technical field of meteorological radars, in particular to a quick-release waveguide structure for an airborne meteorological radar antenna. Background Art

[0002] Airborne weather radar antennas mostly use waveguide slot arrays, so the microwave channel between the antenna and the scanner needs to transmit energy through a waveguide. The existing connection method is usually to butt two waveguides together, and the middle flange is fixed with screws.

[0003] Although fasteners connecting the waveguide can provide stability, a certain amount of operating space needs to be reserved for screw removal, which brings trouble to the later disassembly work. Therefore, it is necessary to propose a quick-release waveguide structure for airborne weather radar antenna. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a quick-release waveguide structure for an airborne weather radar antenna.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A quick-release waveguide structure for an airborne weather radar antenna comprises a double-layer locking frame and a waveguide tube. The upper and lower locking frames are fixedly connected to form a whole. The locking frame consists of an upper cover plate and a lower box plate. The upper cover plate is fixedly connected to the lower box plate and an installation cavity is reserved in the middle. A locking disk and a clamping disk are respectively arranged at symmetrical positions on both sides of the inner side of the lower box plate. The locking disk is an eccentric disk with a protrusion on its edge. The inner side of the clamping disk is designed as a clamping groove for clamping the waveguide tube, and the outer side is designed as a locking groove matched with the protrusion. The outer locking disk pushes the inner clamping disk to slide toward the center of the lower box plate by rotation.

[0007] In a preferred technical solution, a flange is provided at the outer end of the waveguide.

[0008] In a preferred technical solution, the chuck is designed as a crescent-shaped structure, and sliders are respectively provided at both ends of the chuck.

[0009] In a preferred technical solution, straight grooves are respectively formed on both sides of the lower box plate along its length direction, and the sliders at the ends of the chuck are respectively built into the corresponding straight grooves and slide along them.

[0010] In a preferred technical solution, shaft holes are respectively provided on both sides of the plate surface of the lower box plate, and the shaft holes are rotatably fixed with a locking disk via a rotating shaft.

[0011] In a preferred technical solution, a through hole for inserting the waveguide is opened in the center of the locking frame.

[0012] The beneficial effects of the utility model are:

[0013] The quick-release waveguide structure proposed in this scheme solves the problem of inconvenient installation and disassembly of the waveguide tube, which causes trouble for workers. On the one hand, the locking disk with an eccentric structure can push the clamping disk to stably clamp the waveguide tube to ensure its fixation. On the other hand, the locking disk can be rotated to open, which also facilitates the rapid removal of the waveguide tube, providing convenience for workers' operation and easy use.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] In this embodiment, refer to Figure 1-2 A quick-release waveguide structure for an airborne weather radar antenna includes a double-layer locking frame 1 and a waveguide tube 2, wherein a flange 3 is disposed at the outer end of the waveguide tube 2. The upper and lower locking frames 1 are fixedly connected and integrally formed, and a through hole for inserting the waveguide tube 2 is provided in the center of the locking frame 1.

[0019] As attached Figure 2 As shown, the locking frame 1 is composed of an upper cover plate 4 and a lower box plate 5. The upper cover plate 4 is fixedly connected to the lower box plate 5 and a mounting cavity is reserved in the middle.

[0020] A locking disc 6 and a clamping disc 7 are respectively arranged at symmetrical positions on both sides of the inner side of the lower box plate 5, wherein the locking disc 6 is biased outwards and the clamping disc 7 is biased inwards. The locking disc 6 is an eccentric disc, and a protrusion 61 is arranged on its edge.

[0021] The chuck 7 is designed as a symmetrical crescent-shaped structure, the inner side of the chuck 7 is designed as a clamping groove 71 for clamping the waveguide 2 , and the outer side is designed as a locking groove 72 matched with the protrusion 61 .

[0022] Specifically describing the sliding design of the chuck 7, the two ends of the chuck 7 are provided with sliders 73, and at the same time, the two sides of the lower box plate 5 along the length direction thereof are provided with straight grooves 51, and the sliders 73 at the ends of the chuck 7 are respectively built into the corresponding straight grooves 51 and slide along them. The outer locking plate 6 pushes the inner chuck 7 to slide toward the center of the lower box plate 5 by rotating.

[0023] Finally, it should be supplemented that shaft holes 52 are respectively provided on both sides of the plate surface of the lower box plate 5 , and the shaft holes 52 are rotatably fixed with the locking disk 6 via a rotating shaft.

[0024] In this embodiment, under normal circumstances, the protrusion 61 of the locking disk 6 faces outward, and the inner clamping disk 7 is in a state of free sliding horizontally. When installing the waveguide 2, the staff only needs to rotate the locking disk 6 so that the locking disk 6 pushes the clamping disk 7 to slide inward during the rotation process until the protrusion 61 of the locking disk 6 is just embedded in the locking groove 72 on the outer side of the clamping disk 7. In this way, the clamping disks 7 on both sides can clamp the middle waveguide 2, and because the outer locking disk 6 is against the clamping disk 7, it can finally ensure that the connection of the waveguide 2 is fixed. The waveguide gap array can maintain the gap between the butt ends of the two waveguides 2 by artificial regulation.

[0025] When disassembling the waveguide tube 2, the staff only needs to rotate the locking plate 6 outward with force to disengage the protrusion 61 from the locking groove 72. In this way, the chuck 7 is in a loose state, and the staff can easily pull the waveguide tube 2 outward, which is more convenient to operate.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
