Abstract

The utility model provides a bicycle, relates to the transportation field, and more adjustment need be done to the production process of frame to present bicycle when the style of production different dimensional parameters, the utility model provides a bicycle reduces the adjustment of making the production process of frame when the style of production different dimensional parameters, the frame of bicycle contains girder, standpipe, well pipe, the girder is parallel with the horizontal direction, the standpipe is perpendicular with the horizontal direction, and the girder is connected to one end, and the five-way is connected to the other end, well pipe is perpendicular with the horizontal direction, and runs through in the girder, if need adjust vehicle dimensional parameters, only need less length or the welding position of modifying individual pipe material even singly.

Description

Bicycle with a wheel

Technical Field

The utility model belongs to the technical field of the transportation and specifically relates to the bicycle field.

Background

At present, the bicycle needs to be adjusted more in the production process of the bicycle frame due to different geometric angles among the tube materials of the bicycle frame when the styles with different size parameters are produced, the adjustment process is complicated by adjusting the lengths, the notch shapes, the notch angles, the production molds and the like of a plurality of tube materials, and the tube materials among the bicycle frames with different size parameters are difficult to be used universally.

Disclosure of Invention

The utility model discloses aim at: a bicycle is provided that reduces adjustments to the manufacturing process of the frame when producing styles of different dimensional parameters.

The utility model provides an adopted technical scheme of its technical problem is: the frame of bicycle contains girder, standpipe, well pipe, the girder is parallel with the horizontal direction, is the main part of frame, the standpipe is perpendicular with the horizontal direction, and the girder is connected to one end, and the five-way is connected to the other end, well pipe is perpendicular with the horizontal direction, and run through in the girder, insert the seat pipe in the well pipe.

The utility model has the advantages that: the main pipe materials of the frame of the bicycle are in an orthogonal relationship in geometry, if vehicle size parameters such as vehicle length, five-way height, front and rear positions of the five-way, front and rear positions of a seat pipe and the like need to be adjusted, the length or welding position of each pipe material only needs to be modified less or even singly, and the adjustment of the production process is simplified.

Description of the drawings:

FIG. 1 is a perspective view of a bicycle

FIG. 2 is a side view of a bicycle

In the figure: 1. girder 2, standpipe 3, five-way 4, seat pipe 5, seat pipe clamp 6, well pipe.

The specific implementation mode is as follows:

the frame of bicycle in the embodiment contains girder (1), standpipe (2), well pipe (6), girder (1) is parallel with the horizontal direction, for the main part of frame, and the front end connector pipe, the back vent is connected to the rear end, standpipe (2) are perpendicular with the horizontal direction, and girder (1) is connected to one end, and five-way (3) are connected to the other end, well pipe (6) are perpendicular with the horizontal direction, and run through in girder (1), seat pipe clamp (5) are equipped with on its top, inside insert seat pipe (4). The main pipe materials of the frame of the bicycle are in an orthogonal relation in geometry, if vehicle size parameters such as the length of the vehicle, the height of the five-way joint (3), the front and back positions of the seat pipe (4) and the like need to be adjusted, the length or the welding position of each pipe material only needs to be modified less or even singly, and the adjustment of the production process is simplified.

Claims

1. A bicycle, characterized in that: the bicycle frame comprises a crossbeam, a vertical pipe and a middle pipe, wherein the vertical pipe is vertical to the horizontal direction, one end of the vertical pipe is connected with the crossbeam, the other end of the vertical pipe is connected with a five-way joint, the middle pipe is vertical to the horizontal direction and penetrates through the crossbeam, and a seat pipe is inserted into the middle pipe.

2. A cycle as claimed in claim 1, wherein: the crossbeam is parallel to the horizontal direction.

3. A cycle as claimed in claim 1, wherein: the front end of the crossbeam is connected with the head pipe, and the rear end of the crossbeam is connected with the rear fork.
