Description

Carbon fiber antenna support

Technical Field

The utility model relates to an antenna boom's technical field, concretely relates to carbon fiber antenna boom.

Background

During testing processes such as long-distance wireless data transmission in an external field, an antenna needs to be erected for operation. Simply speaking, the antenna is fixed on the top of the antenna bracket and then raised to a height of about 3-4 m. The existing antenna mount is similar in structure to the mount of a camera, including a telescoping tube, a tripod, and an antenna on top of the telescoping tube.

The tripod is basically fixed with the telescopic pipe through a pipe clamp structure, and the antenna is connected with the telescopic pipe through a non-standard structural part when being connected with the telescopic pipe although the antenna has a specific threaded connection structure. The solutions of the connection structure in the prior art are various.

With regard to the bellows, aluminum alloy materials are commonly used in the prior art, typically with a density of 2.7. When the antenna bracket is used, the total length can reach 3-4 meters, so that the telescopic rod occupies most of the weight of the antenna bracket, the whole antenna bracket is heavier, and when the antenna bracket is used in an external field, a larger burden is brought when the antenna bracket is carried, particularly under the condition that the position needs to be frequently moved.

The novel material adopted at present is carbon fiber, the density of which is smaller and is approximately 1.5-1.8, and the tensile strength is very high, so that the carbon fiber can be suitable for the severe environment of an outfield. If the carbon fiber material is used, the weight of the extension tube can be reduced by nearly one time. However, carbon fiber is different from a metal material, and has many problems. First, in the prior art, the two sections of pipe bodies are relatively fixed by using the jackscrews, and the position of the jackscrews is at the overlapped part of the two sections of pipe bodies, but the surface of the metal has enough hardness to resist the jacking of the jackscrews. But carbon fiber tubular product is by carbon cloth layer by layer with resin solidification, in case use jackscrew top tight, the fracture between very easy emergence layer, carbon fiber is not wear-resisting in addition, and the rotatory in-process of jackscrew just can drill out the recess on the carbon fiber surface, in case exert oneself the top tight will destroy the surface wear of carbon fiber pipe. The applicant has experimented with the use of a jackscrew to jack a carbon fiber tube.

Therefore, if the carbon fiber material is used for manufacturing the telescopic tube, the jackscrew must be abandoned and a new structural scheme is used.

It is to be noted that the tube clamp structure used by the antenna 3 and the tripod 2 is an existing structure solution, and the application does not improve the structure.

Different from the prior art, the outer tube 12 and the inner tube 11 are both made of carbon fiber, and the fastening structure 4 is arranged between the inner tube 11 and the outer tube 12.

The fastening structure 4 comprises a support ring 41, an overhanging attachment 42 and a bolt 43.

Wherein the support ring 41 is a broken ring structure having a break 411. The support ring 41 is provided with a plurality of threaded holes 412, the threaded holes 412 are distributed around the axis of the support ring 41 at equal angles, and the threaded holes 412 are through holes. The support ring 41 is disposed inside the outer tube 12, and has an outer wall attached to the inner wall of the outer tube 12 and an inner wall attached to the outer wall of the inner tube 11. The overhanging portion 42 has a cylindrical structure, and a connecting portion 421 is integrally formed at one end thereof. The connection portion 421 has a screw structure. The connecting portion 421 is fitted with the threaded hole 412 and is adapted to be screwed into the threaded hole 412. The overhanging joint 42 is provided with a second through hole 422, and the direction of the second through hole 422 is perpendicular to the axial direction of the overhanging joint 42.
