Description

Technical Field

[0001] The utility model relates to the field of bicycle parts, in particular to a hidden fixing structure of a bicycle vertical pipe. Background Art

[0002] Bicycle is a very good means of transportation. Its kinetic energy comes from manual pedaling, which is very environmentally friendly. It can be used for transportation, competition, sports, etc. Each component of the bicycle is very important. Whether it is the pursuit of riding comfort, body stability, competition ability, etc., the quality and structure of each component must be pursued. The vertical tube (stem) of the bicycle components can be said to be one of the core parts for controlling the steering of the bicycle. It is used to connect the front fork and the handlebar so that the handlebar can control the rotation of the front fork. However, the current common combination structure between the vertical tube and the front fork has gradually failed to meet the needs of most bicycle players. The reason is that with the advancement of technology, the structure of bicycles has become quite mature and has not changed much in recent years. For ordinary players who are not competitive and do not need to pursue extreme performance, small improvements do not have much significance. Therefore, many bicycle players begin to pursue the beauty presented in the appearance. When viewing a bicycle, the overall appearance of the bicycle can be more clearly observed from a side view angle. Therefore, side viewing is the main viewing angle for bicycles. However, among the products currently on the market, the fixation of the vertical tube and the front fork tube must rely on the lateral locking of screws. Therefore, when observing the bicycle from the side, the aforementioned lateral locking screws can be seen, which greatly destroys the overall beauty. Summary of the invention

[0003] Purpose of the invention: The technical problem that the utility model mainly solves is to provide a hidden fixing structure design for a bicycle vertical tube, which not only has a high locking force and can meet the locking force requirements of bicycle assembly, but also has a simple and reasonable structure and simple assembly operation, which improves assembly efficiency and reduces production costs. In addition, the overall shape is beautiful, which not only increases the overall appearance of the bicycle, but also increases its safety.

[0004] Technical solution: The utility model discloses a hidden fixing structure for a bicycle vertical tube, comprising a main handlebar, a clamping block and a hexagonal screw. The main handlebar is an integrated handlebar, and the handlebar is formed by welding a handlebar and a head pipe together. The clamping block is arranged in the head pipe, and a through hole is opened on the head pipe. The hexagonal screw passes through the through hole to fix the clamping block.

[0005] Preferably, four through holes are provided, and four hexagonal screws are provided at the same time, and the four hexagonal screws are provided at positions corresponding to the four corners of the clamping block.

[0006] Preferably, the opening of the through hole located on the surface of the head pipe is arranged as a recessed portion, and the head of the hexagonal screw is completely embedded in the recessed portion.

[0007] Preferably, a groove is provided on the handlebar, and an instrument is embedded in the groove.

[0008] Compared with the prior art, the utility model has the following beneficial effects: through the above method, the utility model provides a hidden fixing structure design of the vertical tube of the bicycle, which not only has a high locking force and can meet the assembly requirements, but also has a beautiful shape, thereby improving the aesthetics of the entire handlebar. After the utility model is installed on the vertical tube of the front fork, the screws used cannot be observed from the side. BRIEF DESCRIPTION OF THE DRAWINGS
