Specific implementation manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Referring to Figures 1-6 , a cleaning device for a bicycle transmission and braking system, includes a nozzle 1 and a water pipe 2 connected to one end of the nozzle 1. A partition plate 3 is fixedly installed inside the nozzle 1. A rectangular hole is opened on the partition plate 3, and a control component for controlling the water flow rate is provided on the partition plate 3.

[0026] One end of the water pipe 2 is connected to a faucet. When the faucet is opened, water will spray out through the water pipe 2 and the nozzle 1, thereby flushing the bicycle transmission and braking system.

[0027] A liquid inlet pipe 4 is fixedly connected to the nozzle 1. One end of the liquid inlet pipe 4 is communicated with the inside of the nozzle 1. A liquid storage tank 5 is fixedly installed at the upper end of the liquid inlet pipe 4. A cleaning agent is filled in the liquid storage tank 5. A sealing plate 6 is fixedly installed at the end of the liquid inlet pipe 4 connected to the nozzle 1. A plurality of liquid outlet holes are opened on the surface of the sealing plate 6. A pressure valve 7 is fixedly installed in the plurality of liquid outlet holes. A moving hole is opened on the sealing plate 6. A moving rod 8 is vertically slidably installed in the moving hole. A disc 9 is fixedly installed at the upper end of the moving rod 8. A moving ring 11 is installed on the sealing plate 6 through a spring rod 10. The side of the moving ring 11 is in sealed sliding contact with the inner wall of the liquid inlet pipe 4. A transmission component for driving the moving rod 8 to move up and down is provided inside the nozzle 1.

[0028] When the water flow enters the nozzle 1, it will drive the moving rod 8 to move up and down through the transmission component. When the moving rod 8 moves upward, it drives the disc 9 to move upward in the liquid inlet pipe 4. At this time, the disc 9 is separated from the moving ring 11, and the cleaning agent in the liquid storage tank 5 will flow to the lower part of the moving ring 11. When the moving rod 8 moves vertically downward, it drives the disc 9 to move vertically downward. During the movement of the disc 9, it will contact the upper surface of the moving ring 11. At this time, the disc 9 will block the inner ring of the moving ring 11 and drive the moving ring 11 to move vertically downward, and the spring rod 10 is compressed. At this time, a sealed space will be formed between the moving ring 11 and the sealing plate 6. As the moving ring 11 continues to move downward, the sealed space decreases and the pressure increases. When the pressure reaches the critical value of the pressure valve 7, the pressure valve 7 opens, and the cleaning agent below the moving ring 11 will be sprayed out from the pressure valve 7 and enter the nozzle 1, where it is mixed with the water in the nozzle 1. The water mixed with the cleaning agent can effectively clean the oil stains and improve the cleaning effect of the cleaning device.

[0029] An annular groove is formed in the inner wall of the nozzle 1. The transmission component includes a turbine 12 rotatably installed in the annular groove, a rotating shaft 13 horizontally and fixedly installed on the turbine 12, a rotating disc 14 fixedly installed at one end of the rotating shaft 13, and a transmission rod 15 rotatably installed on the rotating disc 14. One end of the transmission rod 15 away from the rotating disc 14 is rotatably connected to one end of the moving rod 8.

[0030] When the water flows in the nozzle 1, under the action of the water flow, it will drive the turbine 12 to rotate. At this time, the turbine 12 drives the rotating shaft 13 and the rotating disc 14 to rotate. The rotating connection of the transmission rod 15 and the rotating disc 14 is not located at the center of the rotating disc 14. Therefore, during the rotation of the rotating disc 14, it will drive the moving rod 8 to move up and down through the transmission rod 15.

[0031] The control component includes a U-shaped frame 16 fixedly installed on the partition plate 3, two moving plates 17 symmetrically and slidably installed on the U-shaped frame 16, a plurality of first telescopic springs 18 respectively fixedly installed on the two moving plates 17, and a pressing component for driving the two moving plates 17 to move away from each other. One end of the first telescopic spring 18 away from the moving plate 17 is fixedly connected to the U-shaped frame 16. The moving plate 17 is in sealed sliding contact with the partition plate 3. A circular hole is formed in the nozzle 1. The pressing component includes a pressing rod 19 vertically slidably installed in the circular hole through an elastic part, a V-shaped rod 20 fixedly installed at the lower end of the pressing rod 19, and two limiting blocks 21 respectively fixedly installed on the two moving plates 17. The V-shaped rod 20 is in sliding contact with the two limiting blocks 21. The elastic part includes a pressing block 22 fixedly installed at the upper end of the pressing rod 19 and a second telescopic spring 23 sleeved on the pressing rod 19. The two ends of the second telescopic spring 23 are respectively fixedly connected to the pressing block 22 and the nozzle 1.

[0032] Two moving plates 17 are slidably mounted on the U-shaped frame 16. When it is necessary to control the water flow rate, the pressing block 22 can be pressed to drive the pressing rod 19 to move vertically downward, and the second telescopic spring 23 is compressed. When the pressing rod 19 moves downward, it will drive the V-shaped rod 20 to move vertically downward. At the same time, under the action of the V-shaped rod 20, the two moving plates 17 will be driven to move away from each other through the two limit blocks 21. The larger the distance between the two moving plates 17, the larger the water flow passing through the rectangular hole. The width of the opening of the rectangular hole can be controlled according to the usage situation, and the water flow rate ejected from the nozzle 1 can be controlled, improving the practicability of the cleaning device.

[0033] The diameter of the disc 9 is larger than the aperture of the moving ring 11. A sealing ring is fixedly mounted on the upper surface of the moving ring 11. When the disc 9 contacts the moving ring 11, the disc 9 will contact the sealing ring. Under the action of the seal, the sealing performance between the disc 9 and the moving ring 11 can be improved.

[0034] In the present utility model, when the water flow enters the nozzle 1, it will drive the moving rod 8 to move up and down through the transmission assembly. When the moving rod 8 moves upward, it drives the disc 9 to move upward in the liquid inlet pipe 4. At this time, the disc 9 is separated from the moving ring 11, and the cleaning agent in the liquid storage tank 5 will flow to the lower part of the moving ring 11. When the moving rod 8 moves vertically downward, it drives the disc 9 to move vertically downward. During the movement of the disc 9, it will contact the upper surface of the moving ring 11. At this time, the disc 9 will block the inner ring of the moving ring 11 and drive the moving ring 11 to move vertically downward, and the spring rod 10 is compressed. At this time, a sealed space will be formed between the moving ring 11 and the sealing plate 6. As the moving ring 11 continues to move downward, the sealed space decreases and the pressure increases. When the pressure reaches the critical value of the pressure valve 7, the pressure valve 7 opens, and the cleaning agent below the moving ring 11 will be ejected from the pressure valve 7 and enter the nozzle 1, mixing with the water in the nozzle 1. The water mixed with the cleaning agent can effectively clean the oil stain and improve the cleaning effect of the cleaning device.

[0035] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
