Description

Technical Field

[0001] The utility model relates to a pipe body wiring structure and a bicycle seat tube, and is mainly applied to the technical fields of pipe bodies and bicycles. Background Art

[0002] In recent years, bicycles have been widely accepted by users with different needs because they can be used as a means of transportation, leisure or sports. The development of bicycle components has become more and more diversified and functional, such as brakes, gear shifting and other functional components, and even provide navigation equipment, monitoring instruments that record riding status and warning lights and other electronic components. These functional components and electronic components usually require different wires such as steel cables, pipelines, signal wires or power lines to be laid between the operating end and the action end in order to effectively produce functions and effects. However, no matter how the wires of brakes, gear shifting or electronic components are laid along the outside of the handlebars, vertical tubes or seat tubes, if they are not organized and gathered, the wiring will be loose, scattered and exposed, which will not only destroy the appearance of the whole vehicle, but may also cause safety problems due to the wires accidentally hooking foreign objects.

[0003] Taking the rear warning light as an example, since the rear warning light irradiating backwards is arranged under the seat cushion, its height can provide the best viewing field for the rear vehicles, so most of the rear warning lights are currently installed on the top of the seat tube of the seat cushion assembly and below the seat cushion. However, in order to facilitate the insertion and meet the needs of riders of different heights, the existing seat cushion assembly is usually installed and adjusted in height by inserting the seat tube of the seat cushion assembly into the vertical tube of the frame.

[0004] As mentioned above, laying out the wires on the tube through external routing not only easily causes the routing to be bulky and messy, which affects the appearance of the tube as a whole, but also makes it possible for the wires to be hooked by external foreign objects, which may cause danger. In order to solve the aforementioned problem of external routing of the tube, the industry adopts the method of opening holes at both ends of the circumference of the tube, so that the wires can be routed internally, pass through the through holes into the tube, and then enter the frame to connect the rear warning light and the battery or motor. Although this can solve the problems of clutter and appearance, the processing of holes on the tube will damage the strength of the tube, and rainwater will seep in through the holes, causing rust problems. This will only reduce the strength of the tube and even cause safety problems such as the tube breaking during use, which needs further improvement. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to provide a tube wiring structure and a bicycle seat tube, which can effectively limit and protect the wires without damaging the external appearance of the tube, and at the same time prevent foreign objects from hooking the wires, thereby greatly improving the safety of use; secondly, it can reduce the secondary processing of the tube body to ensure the stress strength of the tube body, and will not cause the tube body to break during use, thereby improving its practicality and overcoming the shortcomings of the prior art.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a tube body wiring structure, which is composed of a tube body, the tube body has a coaxial outer wall and an inner wall, the tube body has a thickened portion extending toward the axis on the inner wall, the outer wall of the tube body has a wiring groove extending along the axis relative to the thickened portion, the depth of the wiring groove of the tube body is greater than the diameter of a wire to be laid, the inner walls on both sides of the wiring groove of the tube body form inner inclined surfaces that converge outwards, and the wiring groove has a necked opening, which is smaller than the diameter of the wire.

[0007] The utility model adopts another technical solution: a bicycle seat tube, which is composed of a tube body and a joint installed on the tube body; the tube body is provided with the tube body wiring structure as described above, the joint has a plug-in section, the joint can be selectively plugged into the top end of the tube body using the plug-in section, and the joint has a hanging part for selectively locking a rear warning light, so that the rear warning light can be electrically connected to the wire.

[0008] Preferably, a limit score line is formed on the outer peripheral wall surface of the tube body adjacent to the top end to limit the insertion depth of the tube body.

[0009] Preferably, the wiring groove of the tube body is formed with an expanded groove portion at a portion exceeding the limit mark line to facilitate bending of the wire and routing of the wire.

[0010] Preferably, the outer wall surface of the tube body is formed with at least one groove below the limit mark, and an O-ring is inserted into the groove to secondary prevent the wire from being exposed from the tube body.

[0011] The beneficial effect of the utility model is as follows: through the display of the aforementioned technical means, the tube wiring structure and the bicycle seat tube using the same utilize the wiring groove of the tube to lay out a wire, so that the wire will not be exposed outside the tube and the wire can be prevented from escaping at will, thereby effectively restricting and protecting the wire and not damaging the external appearance of the tube. At the same time, foreign objects can be prevented from hooking the wire, and the secondary processing of the tube can be reduced to ensure the stress strength of the tube, so as to prevent the tube from breaking during use, thereby greatly improving the safety of use, improving its practicability, effectively increasing its added value, and enhancing its economic benefits.
