bicycle seat tube

technical field

The utility model belongs to the technical field of bicycle frames, in particular to a bicycle standpipe.

Background technique

Bicycle is a means of transportation with a relatively long history. Today, people's awareness of environmental protection is increasing, and more and more people choose to travel by bicycle, a low-carbon and environmentally friendly way. The kind of bicycle is also increasing day by day, and multiple bicycles with special purpose have appeared in recent years, as the mountain bike used for body-building and the variable-speed bicycle used for increasing speed.

Along with the progress of science and technology, the bicycle presents the trend of multifunctional development, and some bicycles equipped with different functional electronic devices have begun to appear on the market. All kinds of electronic equipment are generally equipped with signal wires and current-carrying wires. If these signal wires and current-carrying wires are installed outside the bicycle frame, it will affect the integrity of the bicycle structure.

Utility model content

The purpose of the utility model is to provide a bicycle standpipe for the deficiencies of the prior art, which can allow the signal wires and electric wires of the electronic equipment installed on the bicycle to pass through the bicycle standpipe.

In order to achieve the above object, the utility model adopts the following technical scheme: the bicycle standpipe includes a standpipe body, the inner wall of the standpipe body is provided with a threading groove, and the standpipe is provided with several threading holes, and the threading hole is connected with the The threading slots are connected.

As an improvement of the bicycle standpipe of the utility model, the number of the threading holes is 3, one of the threading holes communicates with the upper pipe of the bicycle frame, and the other two threading holes communicate with the rear of the bicycle frame. The vertical fork is connected. Therefore, the wires can be routed inside the upper tube of the vehicle frame, so that the signal wires and energized wires of the electronic equipment assembled on the bicycle pass through the threading hole communicated with the upper tube of the vehicle frame, enter the threading slot, and then Pass through the other two threading holes and enter the inside of the rear vertical fork of the vehicle frame. The signal wires and energized wires of the electronic products equipped with the bicycle can be installed inside the frame to protect the signal wires and energized wires, prolong their service life, and maintain the integrity of the bicycle structure.

As an improvement of the bicycle standpipe of the utility model, in addition to the threading groove, several reinforcing ribs are provided on the inner wall of the standpipe body. The setting of the reinforcing rib increases the mechanical strength of the bicycle tube.

As an improvement to the bicycle standpipe of the utility model, the reinforcing ribs are evenly distributed on the inner wall of the standpipe body. The stress on the reinforcing rib is even, and the bicycle standpipe is not easy to be bent in one direction.

As an improvement of the bicycle standpipe of the utility model, the upper opening of the standpipe body is provided with a chamfer. The setting of the chamfer makes it easy to insert the seat tube of the bicycle into the body of the stand tube, which is convenient for installation.

As an improvement of the bicycle standpipe of the utility model, the threading hole is circular with a diameter of 8 to 14 mm. The threading hole is set in a circular shape, which is easy to process and reduces the processing cost. The diameter of the threading hole is set to 8 to 14mm to ensure that there is a sufficient size of the aperture for the signal line and the current conducting wire of the electronic device to pass through.

The beneficial effects of the utility model are: to provide a bicycle standpipe, which is provided with threading slots and threading holes, so that the signal lines and electrified wires of the electronic equipment equipped on the bicycle can pass through the bicycle standpipe, ensuring The integrity of the bicycle structure is ensured, and there is enough space in the threading groove to accommodate the signal wires and power wires of the electronic equipment, so as to prevent the signal wires and power wires of the electronic equipment from being crushed after the seat tube of the bicycle is inserted into the standpipe body.

Detailed ways

The utility model and its beneficial effects will be further described in detail in combination with the specific embodiments and the accompanying drawings, but the specific implementation of the utility model is not limited thereto.

As shown in Figures 1 to 3, the bicycle standpipe includes a standpipe body 1, the inner wall of the standpipe body 1 is provided with a threading groove 2, and the standpipe body 1 is provided with three threading holes 3, and the threading hole 3 communicates with the threading groove 2 , the threading hole 3 is circular, and the diameter of the threading hole 3 is 10mm. Wherein, one threading hole 3 communicates with the upper tube 4 of the vehicle frame of the bicycle, and the other two threading holes 3 communicate with the rear vertical fork 5 of the vehicle frame of the bicycle. On the inner wall of the riser body 1 , except for the threading groove 2 , evenly distributed reinforcing ribs 6 are provided to strengthen the mechanical strength of the riser body 1 . A chamfer 7 is provided at the upper opening of the standpipe body 1 to facilitate the installation of a bicycle seat tube (not shown in the figure) in the standpipe body 1 .

During use, the bicycle is equipped with electronic equipment, such as an operation panel is installed on the handlebar, and an LED light bar 8 for warning is installed on the upper tube 4 of the vehicle frame and the rear vertical fork 5 of the vehicle frame. Lead out the energized wire from the operation panel, the energized wire supplies power to the LED light bar 8 installed on the upper tube 4 of the frame, and then the energized wire passes through the inside of the upper tube 4 of the frame, and passes through the threading hole communicated with the inside of the upper tube 4 of the frame 3 penetrate the threading groove 2 of the standpipe body 1, because the threading groove 2 has enough space, the seat tube of the bicycle will not crush the live wire after being inserted into the standpipe body 1. Then the energized wire passes through the threading hole 3 communicated with the rear vertical fork 5 of the vehicle frame, penetrates the rear vertical fork 5 of the vehicle frame, and supplies power to the LED light bar 8 installed on the rear vertical fork 5 of the vehicle frame.

According to the disclosure and teaching of the above specification, those skilled in the art to which the present utility model belongs can also change and modify the above embodiment. Therefore, the utility model is not limited to the above specific implementation manners, and any obvious improvement, replacement or modification made by those skilled in the art on the basis of the utility model shall belong to the protection scope of the utility model.
