Quick butt-joint fixture of end face of waveguide tube

Abstract

The invention discloses a quick butt-joint fixture of an end face of a waveguide tube. The quick butt-joint fixture is composed of a fixed block, a fixture unit, and a clamping plate arranged at the fixture unit. The left side wall of the fixed block is hinged to the left side wall of the fixture unit by a hinge. A cavity is formed inside one side of the fixed block; a first lead screw and a second lead screw are arranged inside the cavity; ends, opposite to each other, of the first lead screw and the second lead screw are in rotation connection with the side wall of the cavity; and the ends,facing each other, of the first lead screw and the second lead screw are connected fixedly and coaxially and a first bevel gear is connected to the connection part vertically and fixedly. Rectangularholes are formed in the two sides of the lower left side wall and the lower right side wall of the cavity; and an L-shaped rod are connected in the two rectangular holes in a sliding manner. The quickbutt-joint fixture is operated conveniently and is capable of fixing a waveguide tube clamped by the fixture, thereby preventing the waveguide tube from being separated and protecting pulse signal transmission from being affected; and a waveguide tube with the small diameter can be fixed and thus the adaptability of the fixture is enhanced.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a quick butt joint fixture for waveguide end faces. Background technique [0002] A hollow metal conduit or a metal-coated tube with a very smooth inner wall; the waveguide is used to transmit ultra-high frequency electromagnetic waves, through which the pulse signal can be transmitted to the destination with minimal loss, and the inner diameter of the waveguide depends on the size of the waveguide. The wavelength of the transmitted signal varies, and it is mostly used in the radio communication, radar, navigation and other radio fields of centimeter wave and millimeter wave. Therefore, the connection of the waveguide requires high precision, otherwise it will affect the propagation of the waveguide to the signal. [0003] After searching, the Chinese patent authorization number is CN104319432B, which discloses a waveguide end-to-face butt joint fixture and a butt joint structur...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem in the prior art that it is impossible to fix the waveguide with a well-connected clamp, and the waveguide with a smaller diameter cannot be fixed, and a quick butt joint fixture for the end face of the waveguide is proposed.
