Problems solved by technology

For example, the patent CN104409797A completes the sealing design by designing a concave-convex structure on the waveguide flange and combining it with a polytetrafluoroethylene sheet, but it is locked by screws, which cannot meet the requirements of quick disassembly, electromagnetic sealing, and cannot solve the problem of limited maintenance space; patents CN208753476U, CN106763017B Invented a device for fast locking by setting large locking rings at both ends of the flange, but there is no sealing measure, and the required operating space is large

Abstract

The invention discloses a waveguide flange capable of realizing rapid assembly, disassembly and sealing and a connecting device thereof. The waveguide flange comprises a first waveguide, a second waveguide, a sealing ring and a locking hoop, the first waveguide comprises a first waveguide tube, one end of the first waveguide tube is connected with a first flange, and the first flange is provided with a first positioning assembly; the second waveguide comprises a second waveguide tube, one end of the second waveguide tube is connected with a second flange, a sealing groove is formed in the middle of the second flange, a sealing ring is installed in the sealing groove, and a second positioning assembly is arranged on the second flange; and the first flange and the second flange are positioned and connected through a first positioning assembly and a second positioning assembly, and the first flange and the second flange are fastened and connected through a locking hoop. The waveguide adopts a flange structure and a locking device thereof so that airtight sealing / electromagnetic shielding and quick assembly and disassembly can be realized, and maintainability is improved.

Description

technical field [0001] The invention belongs to the technical field of microwave waveguide transmission lines, and in particular relates to a waveguide flange capable of fast assembly, disassembly and sealing and a connecting device thereof. Background technique [0002] The waveguide is mainly used for microwave and millimeter wave transmission. It has the advantages of small insertion loss and high power density, and is widely used in the field of microwave transmission. Due to the limitations of the space environment and the transmission distance, it is often necessary to segment the waveguide and assemble it to form a complete transmission line, and each section of the waveguide needs to be fastened and sealed. At present, most of the waveguide structure and installation schemes adopt the connection method that meets the requirements of the national standard, that is, flange structures with mounting holes are arranged at both ends of the waveguide, and the two sections o...
