Abstract
The utility model provides a bicycle saddle tube. The bicycle saddle tube comprises a saddle tube base and a retractable tube, wherein a connection head is arranged on the saddle tube base; one end of the retractable tube is fixedly connected with the saddle tube base through the connection head; the retractable tube is a hollow round tube; the inner wall of the retractable tube comprises four surfaces, two surfaces opposite to each other are arc surfaces, and the other two surfaces are plane surfaces; the connection head works together with the inner wall of the retractable tube. The bicycle saddle tube has the benefits that relative rotation between the saddle tube base and the retractable is prevented.
Description
Technical field
The utility model belongs to bicycle accessories field, especially relates to a kind of bicycle saddle tube.
Background technology
Bicycle saddle tube comprises that hollow telescopic pipe and one are connected to the seat Guan Ji of hollow telescopic pipe one end, seat Guan Ji is for fixing vehicle seat, existing telescopic pipe inwall is circular, after seat Guan Jiyu telescopic pipe is fixedly connected with, under the effect around telescopic pipe center shaft rotational force, seat Guan Jiyu telescopic pipe easily relatively rotates, make vehicle seat and vehicle frame not point-blank, impact is ridden.The technical matters that exists seat Guan Jiyu telescopic pipe easily to relatively rotate.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of bicycle saddle tube, is especially suitable for preventing relatively rotating between a base Guan Ji and telescopic pipe.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: bicycle saddle tube, comprise a Guan Ji and telescopic pipe, and described seat Guan Ji is provided with connector, and one end of described telescopic pipe is fixedly connected with by described connector with described seat Guan Ji; Described telescopic pipe is hollow circular-tube; Described telescopic pipe inwall comprises four faces, and wherein two opposite faces are cambered surface, and two other opposite face is plane, described connector and described telescopic pipe inwall cooperating.
Further, described telescopic pipe tube wall thickness is 2.5mm～3.5mm, and thinnest part thickness is 1mm～2mm.
Further, described telescopic pipe is carbon fiber telescopic pipe.
Further, described telescopic pipe is aluminum alloy telescopic pipe.
Further, described telescopic pipe is titanium alloy telescopic pipe.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, prevent relatively rotating between a Guan Ji and telescopic pipe; Have advantages of simple in structure, reliable and stable.
Accompanying drawing explanation
Fig. 1 is part sectional view of the present utility model;
Fig. 2 is the utility model telescopic pipe sections birds-eye view;
Fig. 3 is the utility model seat pipe base section upward view.
In figure:
1, seat pipe base 2, telescopic pipe 3, connector
The specific embodiment
As Figure 1-3, the utility model bicycle saddle tube, comprises a pipe base 1 and telescopic pipe 2, and seat pipe base 1 is provided with connector 3, and one end of telescopic pipe 2 is fixedly connected with by connector 3 with seat pipe base 1; Telescopic pipe 2 is hollow circular-tube; Telescopic pipe 2 inwalls comprise four faces, and wherein two opposite faces are cambered surface, and two other opposite face is plane, connector 3 and telescopic pipe 2 inwall cooperatings; Telescopic pipe 2 tube wall thickness are 2.5mm～3.5mm, and thinnest part thickness is 1mm～2mm; Telescopic pipe 2 is carbon fiber telescopic pipe 2; Telescopic pipe 2 is aluminum alloy telescopic pipe 2; Telescopic pipe 2 is titanium alloy telescopic pipe 2.
The working process of this example: seat pipe base 1 produces relative to the power of rotating with telescopic pipe 2 under the effect around telescopic pipe 2 center shaft rotational forcees, because two opposite faces of telescopic pipe 2 inwall are cambered surface, another two opposite faces are that the cross-sectional plane of plane and seat pipe base 1 connecting portion is identical with telescopic pipe 2 inner chamber shape of cross sections, can prevent that the pipe base 1 from rotating relative to telescopic pipe 2, the saddle being fixedly connected with seat pipe base 1 is remained and vehicle frame straight line.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
