Moreover, the structure is simple and easy to operate, effectively improving the use effect of the brake.

[0031] In this embodiment, sliding grooves one 13 are formed on both of the two mounting seats 2. U-shaped plates 6 are slidably connected in both of the two sliding grooves one 13. The U-shaped plates 6 are slidably connected to the corresponding spheres 5. Under the action of the pressure of hydraulic oil, the U-shaped plates 6 slide in the sliding grooves one 13 and act on the plurality of spheres 5. During this process, the U-shaped plates 6 push the plurality of spheres 5 and the plurality of spheres 5 are respectively engaged with a plurality of card slots 14.

[0032] In this embodiment, a spring 7 is fixedly connected to one side of the U-shaped plate 6, and one end of the spring 7 is fixedly connected to the mounting seat 2. Due to the elastic potential energy of the spring 7, the U-shaped plate 6 slides reversely in the sliding groove one 13 and returns to its original state. During this process, the U-shaped plate 6 extrudes the hydraulic oil in the sliding groove one 13, and conveys the hydraulic oil into the liquid storage groove 8 through the connection groove on the mounting seat 2.

The U-shaped plate 6 is adapted to the plurality of spheres 5, and the sliding groove one 13 is adapted to the U-shaped plate 6.

[0033] In this embodiment, a liquid storage tank 8 is formed on the mounting base 2. A moving plate 9 is slidably connected in the liquid storage tank 8. The moving plate 9 facilitates the extrusion of the hydraulic oil in the liquid storage tank 8. A connecting groove is formed on the mounting base 2 and is connected to the liquid storage tank 8 and the first sliding groove 13.

By rotating the rotating plate 11 on the threaded rod 10, the threaded rod 10 performs a threaded drive with the mounting base 2. At the same time, one end of the threaded rod 10 rotates on the moving plate 9, and one end of the threaded rod 10 pushes the moving plate 9 to slide in the liquid storage tank 8. At the same time, the moving plate 9 extrudes the hydraulic oil in the liquid storage tank 8. At the same time, through the function of the connecting groove on the mounting base 2, the hydraulic oil is transported into the first sliding groove 13, so that the pressure in the first sliding groove 13 increases. A first sealing ring is fixedly sleeved on the moving plate 9, and the first sealing ring is slidably connected to the mounting base 2 to improve the sealing performance.

[0035] In this embodiment, a first bearing is fixedly sleeved on one end of the threaded rod 10, and the outer wall of the first bearing is fixedly connected to the moving plate 9, which facilitates the rotation of the threaded rod 10. The other end of the threaded rod 10 is fixedly connected to a rotating plate 11, which is convenient for personnel to rotate the threaded rod.

[0036] In this embodiment, a plurality of clamping grooves 14 are formed on both of the two mounting plates 3. The plurality of clamping grooves 14 are respectively adapted to the plurality of spheres 5, which facilitates the limiting and fixing of the two mounting plates 3 by the plurality of spheres 5.

[0037] In this embodiment, a first sealing gasket is fixedly connected to one side of the U-shaped plate 6. The first sealing gasket is slidably connected to the mounting base 2 to improve the sealing performance. A limiting rod is fixedly connected to each of the plurality of spheres 5, and the plurality of limiting rods are respectively slidably connected to the corresponding mounting base 2. The plurality of spheres 5 drive the plurality of limiting rods to slide on the corresponding mounting base 2. At the same time, the plurality of limiting rods can prevent the plurality of spheres 5 from detaching.

[0038] In this embodiment, hydraulic oil is provided in both the liquid storage tank 8 and the first sliding groove 13.

[0039] In this embodiment, the brake caliper body 1 includes a pressure arm and an adjustment mechanism assembly. Through the function of the pressure arm and the adjustment mechanism assembly on the brake caliper body 1, the two mounting bases 2 can be driven, and the two mounting bases 2 drive the two friction blocks 4 to clamp the brake disc through the two mounting plates 3, so as to achieve the braking effect. The specific structures of the brake caliper body 1, the pressure arm and the adjustment mechanism assembly can refer to the document with the application number: 202420361995.3 proposed in this application. This is the prior art and will not be elaborated here.

[0040] Working principle: When in use, the pressure arm on the brake caliper body 1 and the adjustment mechanism assembly are used to drive the two mounting seats 2, and the two mounting seats 2 drive the two friction blocks 4 to clamp the brake disc through the two mounting plates 3, so as to achieve the braking effect;

[0041] The friction block 4 is installed in the installation groove 12 on the mounting seat 2; it should be noted that since the friction block 4 and the mounting plate 3 are usually made into an inseparable whole, the "friction block" of the present utility model refers to a whole composed of the friction block 4 and the mounting plate 3; and multiple card slots 14 on the mounting plate 3 respectively correspond to multiple spheres 5 on the corresponding mounting seat 2. Then, rotate the turning plate 11 on the threaded rod 10, so that the threaded rod 10 is in threaded transmission with its mounting seat 2. At the same time, one end of the threaded rod 10 rotates on the moving plate 9, and one end of the threaded rod 10 pushes the moving plate 9 to slide in the liquid storage tank 8. At the same time, the moving plate 9 squeezes the hydraulic oil in the liquid storage tank 8, and through the action of the connecting groove on its mounting seat 2, the hydraulic oil is conveyed into the sliding groove one 13, so that the pressure in the sliding groove one 13 increases. At this time, under the action of the pressure, the U-shaped plate 6 slides in the sliding groove one 13 and acts on the multiple spheres 5. During this process, the U-shaped plate 6 pushes the multiple spheres 5 and makes the multiple spheres 5 respectively engage with the multiple card slots 14. At the same time, through the blocking and limiting of the multiple spheres 5 by the U-shaped plate 6, the multiple spheres 5 limit and fix the corresponding friction block 4, so as to achieve the effect of quickly installing the friction block 4;

[0042] During the process of the U-shaped plate 6 sliding in the sliding groove one 13, the U-shaped plate 6 pulls the spring 7, so that the spring 7 is stretched and stores energy;

[0043] When it is necessary to disassemble the friction block 4, by reversely rotating the turning plate 11 and the transmission of the threaded rod 10, the moving plate 9 returns to its original state. At this time, under the action of the elastic potential energy of the spring 7, the U-shaped plate 6 slides reversely in the sliding groove one 13 and returns to its original state. During this process, the U-shaped plate 6 squeezes the hydraulic oil in the sliding groove one 13, and through the action of the connecting groove on the mounting seat 2, conveys the hydraulic oil into the liquid storage tank 8. At the same time, the U-shaped plate 6 is separated from the multiple spheres 5, so as to achieve the purpose of releasing the limit on the multiple spheres 5, and further enable the multiple spheres 5 to move on the corresponding mounting seat 2, and further achieve the purpose of releasing the limit on the friction block 4. Then, the friction block 4 is taken out from the installation groove 12, so as to achieve the effect of quickly disassembling the friction block 4.

[0044] The technical progress obtained by the present utility model compared with the prior art is that through the cooperation of each component, the friction block 4 can be quickly installed and disassembled without external tools, which improves the convenience and efficiency. Moreover, the structure is simple and easy to operate, effectively improving the use effect of the brake.
