When the hydraulic oil enters the interior of the connecting sleeve 12, the hydraulic oil enters the interior of the second sleeve 17 through the channel on one side of the first sleeve 13. At the same time, a fixed cylinder 16 is rotatably installed on one side of the second sleeve 17, and the hydraulic oil will also enter the interior of the fixed cylinder 16 for retention. A second fixing ring 15 is fixedly installed on the surface of the second sleeve 17, and a fan-shaped plate 18 is fixedly installed inside each second sleeve 17.
[0024] Two docking plates 19 are fixedly installed on the side end of the second fixing ring 15. A spring button 21 is slidably installed on the outside of each docking plate 19. Two positioning cylinders 22 are fixedly installed on the side end of each second fixing ring 15. A slide rod 24 is slidably installed inside each positioning cylinder 22. A spring rod 23 is fixedly installed on the side end of each slide rod 24. The second fixing ring 15 pushes the spring button 21 to rub against the inside of the first fixing ring 14. The top of the spring button 21 is an arc-shaped design. The spring button 21 is squeezed into the inside of the docking plate 19. At the same time, the spring button 2 The spring installed at the bottom end of 1 pushes the spring button 21 to pop out again and is clamped on the side end of the first fixing ring 14 to limit the position of the second fixing ring 15. At the same time, by rotating the fixing cylinder 16, the fixing cylinder 16 is rotated on the side end of the second sleeve 17. The threaded sleeve on one side of the fixing cylinder 16 rotates with the inner side wall of the second sleeve 17, allowing the fixing cylinder 16 to be removed from the side end of the second sleeve 17. The first fixing ring 14 is fixedly installed on the surface of the first sleeve 13, and a gear sleeve is installed on the side end of each fixing cylinder 16 to dock with the inner side wall of the second sleeve 17.
[0025] Working principle:
[0026] In the first step, when the brake pedal is depressed, the hydraulic oil is pressurized and transported to the inside of the caliper body 11 through the brake pipe. The pressure of the hydraulic oil pushes the piston inside the caliper body 11 to move outward, so that the brake pad is tightly pressed against the brake disc. Due to the friction between the brake pad and the brake disc, the rotation of the wheel is hindered, thereby achieving braking of the car. At the same time, when the hydraulic oil enters the interior of the connecting sleeve 12, the hydraulic oil enters the interior of the second sleeve 17 through the channel on one side of the first sleeve 13. At the same time, a fixed cylinder 16 is rotatably installed on one side of the second sleeve 17, and the hydraulic oil will also enter the interior of the fixed cylinder 16 for retention. By pushing the fixed cylinder 16, the side end of the fixed cylinder 16 is fixedly connected to the second sleeve 17, driving the second sleeve 17 to slide on the side end of the first sleeve 13. A slide groove is opened on one side of the first sleeve 13, and the side end of the second sleeve 17 flows inside the slide groove, allowing the second sleeve 17 to drive the fan plate 18 to move toward the inside of the first sleeve 13.
[0027] In the second step, the surface of the fan-shaped plate 18 is a convex design, which is made of rubber. The fan-shaped plate 18 is telescopically inserted into the interior of the first sleeve 13 to block and close the channel inside the first sleeve 13. At the same time, during the movement of the second sleeve 17, the second fixing ring 15 drives the docking plate 19 to slide inside the first fixing ring 14. The docking plate 19 slides inside the first fixing ring 14, and the distance between the second fixing ring 15 and the first fixing ring 14 is reduced. The second fixing ring 15 pushes the spring button 21 to rub against the inside of the first fixing ring 14. The top of the spring button 21 is an arc-shaped design. The spring button 21 is squeezed into the interior of the docking plate 19. At the same time, the spring installed at the bottom of the spring button 21 pushes the spring button 21. It pops up again and is clamped on the side end of the first fixing ring 14 to limit the position of the second fixing ring 15. At the same time, by rotating the fixing cylinder 16, the fixing cylinder 16 is rotated at the side end of the second sleeve 17. The rotating fixing cylinder 16 squeezes the top of the slide rod 24, applies thrust to the slide rod 24, and makes the slide rod 24 slide toward the inside of the positioning cylinder 22 to squeeze the spring rod 23 for compression. The threaded sleeve on one side of the fixing cylinder 16 rotates with the inner side wall of the second sleeve 17, so that the fixing cylinder 16 is removed from the side end of the second sleeve 17. At the same time, hydraulic oil is retained in the interior of the fixing cylinder 16. By checking the hydraulic oil inside the fixing cylinder 16, the hydraulic oil circulating inside the caliper body 11 can be replaced to increase safety in use.
[0028] Finally, it should be noted that the above embodiments are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
