Abstract
Description
Technical Field
[0001] This utility model relates to the field of brake cables, specifically a brake cable tension adjustment device. Background Technology
[0002] Brake cables, as a key component connecting the brake lever or pedal to the braking device, are typically composed of multiple strands of high-strength steel wires and are wrapped in a protective sleeve. Their main function is to accurately and efficiently transmit the force applied by the driver to the brake control components to the brake actuator, causing the braking device to produce a braking effect, thereby achieving effective control of the vehicle or equipment speed and ensuring safe stopping.
[0003] Currently, the tension of brake cables is generally adjusted by a specific adjusting nut. In bicycle braking systems, there is an adjusting nut at the brake caliper or brake lever. By rotating the nut, maintenance personnel or users can change the position of the brake cable at the fixed point, thereby adjusting the overall tension of the brake cable.
[0004] When adjusting the tightness of the brake cable, maintenance tools are usually needed to tighten it. When using tools to tighten the brake cable, a large amount of force needs to be applied. This method of tightening the brake cable with maintenance tools is cumbersome and physically demanding. Utility Model Content

First, the adjuster 5 is fixedly installed on the vehicle crossbeam 1 using the mounting ring 7 and mounting sleeve 701. Then, the brake cable 3 is placed inside the adjuster 5. The driver 6 is rotated using an iron bar. The driver 6 drives the fastening plate 8 to pull the brake cable 3. According to the lever principle, the rotation of the driver 6 by the iron bar reduces the force required for manual rotation of the driver 6, thus making it easier for personnel to adjust the tightness of the brake cable 3.
[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The bottom of the regulator 5 is fixed with a mounting ring 7, and the bottom end of the mounting ring 7 is movably connected with a mounting sleeve 701. The outer wall of the regulator 5 is provided with an anti-slip pad 502. The mounting ring 7 at the bottom end of the regulator 5 is placed on the outer wall of the vehicle crossbeam 1, the mounting sleeve 701 is flipped over, and then the mounting sleeve 701 is fixedly connected to the mounting ring 7 with bolts, so that the regulator 5 is installed and fixed on the vehicle crossbeam 1. This makes it convenient for personnel to install and fix the regulator 5 on the vehicle crossbeam 1. In addition, the anti-slip pad 502 on the surface of the regulator 5 can increase the friction between the regulator 5 and the personnel's hands, preventing the personnel from slipping when holding the regulator 5.
[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 Both the mounting ring 7 and the mounting sleeve 701 have gaskets inside, and the gaskets have a certain elasticity. When the mounting ring 7 and the mounting sleeve 701 are fixed on the vehicle crossbeam by bolts, the mounting ring 7 and the mounting sleeve 701 press against the outer wall of the vehicle crossbeam 1 through the gaskets, so that the mounting ring 7 and the mounting sleeve 701 can be firmly fixed on the vehicle crossbeam 1.
[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 Limiting blocks 801 are provided on both sides of the fastening plate 8, and the limiting blocks 801 slide inside the regulator 5. When the fastening plate 8 moves inside the regulator 5, the regulator 5 limits the fastening plate through the limiting blocks 801 to prevent the fastening plate 8 from deflecting during its movement due to uneven force on its surface.
[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The top of the fastening plate 8 has a groove 802, which is U-shaped. After opening the cover plate 501, the limiting block 301 at the end of the brake line 3 is placed inside the adjuster 5, and the brake line 3 is fastened in the groove 802 of the fastening plate 8. The groove 802 limits the limiting block 301, so that the fastening plate 8 can pull the brake line 3 during movement.
[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The width of the groove 802 is greater than the diameter of the brake line 3. When the brake line 3 is placed inside the groove 802, the limiting block 301 is located on one side of the groove 802, and the groove 802 limits the limiting block 301.
[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The driver 6 is pentagonal, and the outer wall of the driver 6 has a socket 602. The driver 6 is pentagonal, and each side of the driver 6 has a socket 602, so that when the driver 6 is rotated, the operator can adjust the rotation angle of the driver 6.
[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 One end of the regulator 5 is fixed with a fixing plate 601, and the driver 6 is sleeved on the end of the fixing plate 601. The fixing plate 601 limits the driver 6 to prevent the driver 6 from shaking during rotation.
[0041] In practical operation, the following steps are taken: First, the mounting ring 7 at the bottom of the adjuster 5 is fitted onto the outer wall of the vehicle crossbeam 1. The mounting sleeve 701 is then flipped over, and bolts are used to fix the mounting sleeve 701 to the mounting ring 7, thus fixing the adjuster 5 onto the vehicle crossbeam 1. The cover plate 501 is then opened, and the limiting block 301 at the end of the brake cable 3 is placed inside the adjuster 5. The brake cable 3 is then clipped into the groove 802 of the fastening plate 8. The cover plate 501 is then closed, and the nut 4 is rotated. Rotating the nut 4 releases the retainer 201 from the brake. After securing the brake cable 3, insert the iron rod into the socket 602 on the outer wall of the driver 6. Press the cover plate 501 with your hand to prevent the brake cable 3 from slipping out of the regulator 5. Rotate the iron rod to make the driver 6 rotate.
