An equilateral triangle carbon fiber telescopic rod

Abstract

The invention discloses an equilateral triangular carbon fiber telescopic rod. The shape of a single pipe is an equilateral triangular prism shape, including an inner conduit at the front end, a connecting pipe in the middle and an outer conduit at the tail end. The shape of the inner conduit is consistent with that of the connecting pipe. The shape of the outer conduit is larger than that of the connecting pipe, and protrudes from the surface of the connecting pipe; the hole of the inner conduit is smaller than the connecting hole of the connecting pipe, and the inner wall of the inner conduit hole protrudes from the inner wall of the connecting pipe hole, and the connecting hole is consistent with the hole of the outer conduit; the inner conduit , the inner conduit hole, the connecting pipe, the connecting pipe hole, the outer conduit and the outer conduit hole are coaxial; at least two single pipes constitute the whole telescopic rod. The invention adopts the structure of equilateral triangle, the matching gap between the inner layers and the outer layer is good, the coaxiality is high, and the expansion and contraction is relatively stable; the radial position of the carbon fiber rod is consistent during the expansion process, the corresponding resistance is uniform, and the straightness High, can be widely used in the fields of automatic telescopic arm, automatic parallel stretching rod, automatic side hook hanging rod and calligraphy and painting paper stretching rod products.

Description

technical field [0001] The invention relates to the technical field of carbon fiber rod products, in particular to a carbon fiber telescopic rod. Background technique [0002] Telescopic rods are used in many fields because they can be changed in length. The carbon fiber telescopic rods in the prior art are all tapered circular tubes, and the tapers are relatively large, and they are all fish rod types. When the multi-layer tube is inlaid, the outer tube and the inner tube can rotate mutually. The gap between the tube and the tube is inversely proportional to the pull-out length of the rod, and self-locking occurs when it is stretched to the longest. The disadvantage of this traditional telescopic rod is that there are inconsistencies in the radial relative angular position between the inlaid tubes during the expansion and contraction process, and the axial resistance and coaxiality change with the pull-out length, which weakens its application effect and restricts its use....
