Description

Technical Field

[0001] This utility model belongs to the technical field of mechanical parts for transportation vehicles, specifically relating to a brake grip for a bicycle. Background Technology

[0002] The bicycle brake lever is a key control component of the bicycle braking system. By applying force with the hand, it can activate the braking system to achieve deceleration or stopping.

[0003] Existing bicycle brake grips have different handlebar diameters depending on the brand and model of the bicycle, such as the common 22.2mm and 25.4mm. Traditional brake grips are often only compatible with a single diameter. If the handlebar diameter does not match, problems such as inability to install or looseness and wobbling after installation will occur. Therefore, this utility model proposes a bicycle brake grip.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4This utility model provides a technical solution: a bicycle brake grip, including a main body 1, a brake fine-tuning knob 3 disposed on one side of the top of the main body 1, and a handle 2 disposed on the other side of the top of the main body 1. An adjustable diameter mounting assembly 5 is disposed on the inner side of the main body 1. The adjustable diameter mounting assembly 5 consists of a diameter A 51, a diameter B mounting sleeve 52, multiple positioning components 53, and multiple engaging components 54. The diameter A 51 is opened on the inner side of the main body 1, the diameter B mounting sleeve 52 is disposed inside the diameter A 51, and the multiple engaging components 54 are disposed at the connection between the outer side of the diameter B mounting sleeve 52 and the inner wall of the diameter A 51. The multiple engaging components 54 are all disposed on both sides of the main body 1. Each of the multiple engaging components 54 consists of a slot 541 and a block 542. The slot 541 is located inside the diameter A 51, and the block 542 is located inside the slot 541. The end of the block 542 is fixed to the outer wall of the diameter B mounting sleeve 52. The surface of the block 542 is adapted to the inner wall of the slot 541. The cross-section of the block 542 is T-shaped, and the length of the block 542 is the same as the depth of the diameter B mounting sleeve 52. Multiple positioning components 53 consist of a threaded post 531, a telescopic groove 532, a movable component 533, and a positioning groove. The movable component 533 consists of a movable groove 5331 and a movable block 5332. The movable groove 5331 is located inside the main body 1. On the side, the movable block 5332 is disposed inside the movable groove 5331. When it is necessary to disassemble the diameter B mounting sleeve 52 to adapt the brake grip to the size of the bicycle handlebar, the movable block 5332 is pushed, causing it to rotate inside the movable groove 5331. Through the threaded connection between the threaded post 531 and the movable block 5332, the end of the movable component 533 separates from the positioning groove that engages with the outer wall of the diameter B mounting sleeve 52, causing the diameter B mounting sleeve 52 to lose its limiting position with the diameter A51. Then, the diameter B mounting sleeve 52 is slidably separated from the diameter A51, completing the adaptation of the diameter B mounting sleeve 52, thereby achieving the size of the brake grip mounting diameter. The adjustable grip has a telescopic groove 532 on the inner side of the main body 1, which is connected to the movable groove 5331. A threaded post 531 passes through the inner side of the movable block 5332 and the inner side of the telescopic groove 532. The surface of the threaded post 531 is threadedly connected to the inner side of the movable block 5332. A positioning groove is opened on the outer surface of the diameter B mounting sleeve 52. A brake stroke adjustment bolt 4 is provided on the inner side of the main body 1. A fixing bolt 6 passes through the bottom of the main body 1. The fixing bolt 6 passes through the main body 1 and the adjustable diameter mounting component 5, which firmly fixes the entire grip to the bicycle handlebars, preventing the grip from loosening due to vibration or force during use, and ensuring the stability and safety of the braking system.

[0021] In this embodiment, preferably, a silicone pad is fixed to the inner wall of the B-diameter mounting sleeve 52. The elasticity of the silicone pad can fill the tiny gap between the handlebar and the mounting sleeve, making the fit tighter after installation, avoiding loosening and shaking caused by slight differences in diameter, and improving structural stability.

[0022] The working principle and usage process of this utility model: When the brake lever is in operation, rotating the brake fine adjustment knob 3 can finely adjust the tension of the brake cable through the internal thread structure, thereby achieving fine adjustment of the brake sensitivity. Tightening the brake stroke adjustment bolt 4 can adjust the relative position of the handle 2 and the main body 1, optimize the lever arm when braking, and make it easier for the rider to squeeze the handle.

[0023] When the rider squeezes the handle 2, the force exerted by the hand is amplified by the lever principle, using the connecting shaft with the main body 1 as the fulcrum, and transmitted to the brake cable, thereby driving the brake device to clamp the wheel and achieve braking.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
