Description

Technical Field

[0001] This utility model relates to the field of bicycle accessories technology, specifically a bicycle handlebar. Background Technology

[0002] As a crucial control component during cycling, the handlebars' structural design directly impacts riding comfort, handling, and accessory expandability. Traditional bicycle handlebars suffer from the following shortcomings: the connection between the handlebar assembly and the main stem is limited, making it difficult to flexibly adjust the handlebar assembly position according to different riding needs (such as different hand sizes and riding postures); the handlebars have poor compatibility with various accessories (such as lights, cycling computers, and phone holders), resulting in cumbersome installation; the connection structure between the handlebars and the bicycle fork lacks stability, easily loosening over time and affecting riding safety; and the grip design is inadequate in terms of anti-slip and comfort, leading to slippage and hand fatigue in wet or prolonged riding conditions.

[0003] Therefore, there is an urgent need for a bicycle handlebar that is flexible, adaptable, structurally stable, and comfortable to hold. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a bicycle handlebar, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bicycle handlebar, comprising a main stem and a handlebar assembly.

[0006] Main shaft structure: The main shaft includes the shaft body, with grooves at both ends to guide the sliding of the handlebar assembly. A long hole along the length of the shaft body is located at the bottom center of the groove, allowing for adjustment and fixation of the handlebar assembly using adjusting bolts. A connecting beam is fixedly connected to the lower center of the front end of the shaft body, connecting the shaft body and the sleeve. It adopts a Z-shaped structure, ensuring structural strength while adapting to the installation space of the bicycle fork. A sleeve is fixedly connected to the end of the connecting beam away from the shaft body. The sleeve has a snap-fit ​​structure with an open rear end for quick assembly with the bicycle fork stem. The inner wall has internal anti-slip textures to increase friction with the fork stem and improve connection stability. Ear plates are located on both sides of the rear opening, with connecting holes between the two side walls of the ear plates. Bolts passing through these connecting holes further secure the sleeve to the fork stem.

[0007] Handlebar assembly structure: The handlebar assembly includes a sliding arm that slides within a T-shaped groove. The sliding arm's cross-section is also T-shaped, ensuring stable sliding and preventing detachment. An adjusting bolt is fixedly connected to the bottom of the sliding arm. This bolt passes through a corresponding elongated hole and is secured with a nut. Loosening the nut allows the adjusting bolt to slide along the length of the shaft within the elongated hole, adjusting the position of the handlebar assembly on the shaft. Tightening the nut secures the position. A handlebar accessory mounting platform is fixedly connected to the rear side of the sliding arm, away from the main shaft. The top of the platform has a rectangular surface with evenly spaced anti-slip grooves to increase friction during installation and improve stability. Four threaded mounting holes are arranged in a rectangular array on the handlebar. The handlebar mounting platform facilitates the installation of various handlebar accessories, such as speedometer brackets and lights. Bolts are used to secure the components to the mounting holes. A handlebar accessory mounting base is fixedly connected to the side of the mounting platform, featuring a single, oblong hole aligned with the length of the mounting base. This hole accommodates accessories of different sizes and mounting hole positions, improving compatibility. A curved grip handle is fixedly connected to the rear of the mounting platform. The outer surface is covered with anti-slip teeth, which are raised strips aligned with the length of the grip handle. These teeth are evenly distributed to increase friction during gripping, enhancing anti-slip performance and comfort, and reducing hand fatigue during long rides.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] 1. In this utility model, the position can be flexibly adjusted. Through the cooperation of the sliding groove, the elongated hole and the adjusting fastening bolt, the position of the handlebar assembly can be flexibly adjusted along the length of the main body to adapt to the needs of different riders' hand sizes and riding postures, thereby improving riding comfort and control convenience. The accessories are highly compatible. The mounting holes of the handlebar accessory mounting platform and the waist-shaped holes of the handlebar accessory mounting seat can be adapted to the installation of a variety of handlebar accessories. The installation operation is simple and expands the functionality and practicality of the handlebar.

[0010] 2. In this utility model, the structure is stable and reliable. The Z-shaped connecting beam and the sleeve-shaped connecting tube cooperate with the inner anti-slip texture and the fastening of the connecting hole to make the main rod body and the bicycle front fork firmly connected and not easy to loosen. The sliding cooperation between the T-shaped slide groove and the sliding arm ensures the structural stability of the handlebar assembly during adjustment and use. It is comfortable and non-slip to hold. The arc-shaped grip handle conforms to the curve of the human palm. The anti-slip teeth increase the grip friction, effectively preventing slippage during riding, while relieving hand fatigue during long-term riding and improving the riding experience.
