Description

Technical Field

[0001] This utility model relates to the field of bicycle handlebar technology, and in particular to a bicycle handlebar that is easy to adjust in angle. Background Technology

[0002] Bicycle handlebars play a crucial role in steering, maintaining balance, and assisting riding. They are the key component for controlling the direction of the bicycle. By turning the handlebars, the rider changes the direction of the front wheel, thus determining the bicycle's path. This allows the rider to flexibly avoid obstacles and choose suitable routes. During riding, the rider relies on the handlebars to adjust their center of gravity and maintain the bicycle's balance.

[0003] Chinese utility model patent CN218172487U discloses a bicycle handlebar. The key technical points are: it includes a stem for mounting on the fork stem, a fixing component fixedly mounted on the stem, a handlebar body fixedly mounted on the fixing component, and mounting bolts for fixing the fixing component to the stem; the handlebar body has two sides that slope downwards from the center, and the handlebar body also has several fitting holes for engaging with the fixing component, allowing for height adjustment by flipping the handlebar body for installation. This application has the advantage of improving the usability of the handlebar.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: Traditional bicycle handlebars are generally fixed by means of bolts, which are highly stable, but the operation is cumbersome when adjusting the angle. The adjustment process requires special tools such as Allen wrenches and torque wrenches, and the operation process is complicated. If the angle suddenly shifts during riding, it is impossible to make emergency adjustments without tools, which affects the continuity of the stroke. Moreover, the adjustment accuracy depends on experience. Utility Model Content

[0038] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] like Figures 1-5 As shown in the figure, this application discloses a bicycle handlebar that is easy to adjust in angle, including a U-shaped mounting base 1, a handlebar stem 2, a handlebar crossbar 3, a bicycle handlebar grip assembly, and an angle adjustment assembly 4. Brakes and other components can be installed on both sides of the handlebar crossbar 3, all of which are existing mature devices.

[0040] like Figure 3 As shown, the U-shaped mounting base 1 has mounting holes 5 at both ends, and guide holes 6 are provided on the upper side of the mounting holes 5 at both ends of the U-shaped mounting base 1. The guide holes 6 have an arc-shaped structure. Guide rods 9 are fixedly installed at both ends of the handlebar 2. One end of the guide rod 9 extends into the guide hole 6. When in use, the center of the arc-shaped guide hole 6 coincides with the center of the rotating rod 7. When the angle of the bicycle handlebar is manually adjusted, the guide rods 9 at both ends of the handlebar 2 move in the guide hole 6, so that the handlebar 2 moves smoothly. At the same time, it also limits the swaying of the handlebar 2 in bumpy scenarios and improves the overall rigidity of the structure.

[0041] Rotate one end of the upright 2 and install it inside the U-shaped mounting base 1. Fix the rotating rods 7 at both ends of the upright 2 and insert one end of the rotating rods 7 into the mounting hole 5.

[0042] The crossbar 3 is fixedly installed on the upper end of the upright bar 2;

[0043] The bicycle handlebar grip assembly is fixedly installed at both ends of the handlebar 3. The bicycle handlebar grip assembly includes a first handlebar grip 10 and a second handlebar grip 11. The first handlebar grip 10 is fixedly installed at one end of the handlebar 3, and the second handlebar grip 11 is fixedly installed at the other end of the handlebar 3. Both the first handlebar grip 10 and the second handlebar grip 11 are provided with handlebar sleeves 12 on their outer sides. The handlebar sleeves 12 are made of silicone. When in use, the silicone handlebar sleeves 12 have anti-slip and shock-absorbing properties, improving grip comfort.

[0044] like Figure 4 and Figure 5 As shown, the angle adjustment component 4 includes:

[0045] The damping telescopic rod 401 has a circular groove 8 at one end of the rotating rod 7, and one end of the damping telescopic rod 401 is rotatably installed in the circular groove 8. A spring 402 is sleeved on the outside of the damping telescopic rod 401.

[0046] Rotate the circular plate 403, one end of which is fixedly connected to the free end of the damping telescopic rod 401;

[0047] Limiting rods 404 are arranged in a circular array at one end of the rotating circular plate 403. Positioning grooves 405 are arranged in a circular array at both ends of the upright rod 2 and the U-shaped mounting base 1. One end of the limiting rods 404 extends into the positioning groove 405. One end of the damping telescopic rod 401 is mounted in the circular groove 8 via a plane bearing. One end of the spring 402 is fixedly connected to the rotating circular plate 403, and the other end of the spring 402 is rotatably mounted in the circular groove 8. During use, the damping telescopic rod 401, spring 402, and limiting rods 404 are all made of stainless steel and use wear-resistant components such as plane bearings to extend their service life. The number of positioning grooves 405 is determined according to actual needs. One end of the upright rod 2 has a semi-circular structure. When the upright rod 2 is rotated to adjust its angle, its own positioning groove 405 will rotate with it. When fixed, the limiting rods 404 can simultaneously embed into two positioning grooves 405. When the angle needs to be adjusted, first manually move the rotating disc 403 outward so that the limiting rod 404 at one end disengages from the positioning groove 405, releasing the fixing effect on the handlebar stem 2. Place one end of the limiting rod 404 in the gap between the positioning grooves 405, and then adjust the angle of the bicycle handlebars according to the actual needs. The angle of the bicycle handlebars can be adjusted with the help of the position of the positioning groove 405. At this time, the free end of the damping telescopic rod 401 moves, and the spring 402 is stretched. After adjusting the angle, move the limiting rod 404 to the corresponding end of the positioning groove 405. Under the action of the deformation force of the spring 402, it automatically resets and the limiting rod 404 is embedded in the corresponding positioning groove 405, completing the locking. The spring 402 provides a continuous preload force to ensure that the limiting rod 404 and the positioning groove 405 are tightly engaged. With the buffering effect of the damping telescopic rod 401, it effectively resists the loosening caused by riding vibration.
