Description

Technical Field

[0001] This utility model relates to the field of friction pad technology, and in particular to a friction pad for a disc brake. Background Technology

[0002] Low-voltage disc brakes are braking devices that use stationary brake discs to clamp onto rotating brake discs, generating friction to reduce wheel speed. Hydraulic disc brakes are available, controlled by hydraulic systems. Their main components include the brake disc, caliper, brake pads, and brake lines. Disc brakes are characterized by rapid heat dissipation, light weight, simple construction, easy adjustment, good high-temperature resistance under high loads, and stable braking performance. However, most existing disc brake systems use multiple screws to mount the friction pads to the mounting plate. When the friction pads wear out, replacing them requires removing many screws, increasing workload, making the operation cumbersome and time-consuming, thus presenting certain limitations. Utility Model Content

[0003] The purpose of this utility model is to provide a disc brake friction pad to solve the problems mentioned in the background art and facilitate its promotion.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A disc brake friction pad includes a mounting plate with a connecting groove. A connecting block is movably connected within the connecting groove. A friction pad body is fixedly connected to the top of the connecting block. The connecting block has symmetrical slots on both sides of its outer wall. The mounting plate has symmetrical grooves on both sides of its inner wall. A U-shaped locking rod is symmetrically slidably connected within each groove. A rack is fixedly connected to one side of the outer wall of the U-shaped locking rod, meshing with a gear. A rack is meshed with the other side of the gear, meshing with a second rack. A moving rod is fixedly connected to the other end of the second rack. A spring is fixedly connected between the outer wall of the U-shaped locking rod and the inner wall of the connecting groove. The mounting plate has symmetrical inner grooves corresponding to the connecting groove on both sides of its outer wall. One side of the moving rod passes through the connecting groove and extends into the inner groove. A button is fixedly connected to one end of the moving rod in the inner groove. A sliding groove is formed on the inner wall of the connecting groove. The other end of the moving rod extends into the sliding groove and is fixedly connected to a slider, which is slidably connected to the sliding groove.

[0006] Furthermore, the U-shaped locking rod engages with the locking slot.

[0007] Furthermore, the gear is rotatably connected between the inner top surface and the inner bottom surface of the groove via a bearing.

[0008] Furthermore, the outer walls of the connecting block are symmetrically connected with limiting blocks, and the inner wall of the connecting groove is provided with a limiting groove that is nested and slidably engaged with the limiting blocks.

[0009] Furthermore, a cover plate is movably connected within the inner groove.

[0010] The beneficial effects of this utility model are as follows:

[0011] This utility model discloses a disc brake friction pad. When the friction pad body needs to be replaced after a period of use, pressing a button moves the moving rod, which in turn drives the gear to rotate via rack two, which in turn moves rack one. Then, one end of the U-shaped locking rod slides into the groove, and the other end of the U-shaped locking rod disengages from the groove. Finally, the connecting block can be pulled out of the connecting groove, achieving quick disassembly of the connecting block and the friction pad body. The operation is simple.

[0020] Depend on Figures 1 to 4 As shown, a disc brake friction pad includes a mounting plate 1. A connecting groove 2 is formed on the mounting plate 1, and a connecting block 3 is movably connected within the connecting groove 2. A friction pad body 4 is fixedly connected to the top of the connecting block 3. Slots 5 are symmetrically formed on both sides of the outer wall of the connecting block 3. Grooves 6 are symmetrically formed on both sides of the inner wall of the mounting plate 1. U-shaped locking rods 7 are symmetrically slidably connected within the grooves 6. A rack 8 is fixedly connected to one side of the outer wall of the U-shaped locking rod 7, and a gear 9 is meshed with the rack 8. The gear 9 is rotatably connected between the inner top and inner bottom surfaces of the groove 6 via a bearing. A rack 10 is meshed with the other side of the gear 9, and a moving rod 11 is fixedly connected to the other end of the rack 10. A spring 12 is fixedly connected between the outer wall of the U-shaped locking rod 7 and the inner wall of the connecting groove 2. Inner grooves 13, corresponding to the connecting groove 2, are symmetrically formed on both sides of the outer wall of the mounting plate 1. One side of the moving rod 11 passes through the connecting groove 2 and extends into the interior of the inner groove 13. A button 14 is fixedly connected to one end of the moving rod 11 located in the inner groove 13. A sliding groove 15 is provided on the inner wall of the connecting groove 2. The other end of the moving rod 11 extends into the interior of the sliding groove 15 and is fixedly connected to a slider 16. The slider 16 is slidably connected to the sliding groove 15. When the friction pad body 4 needs to be replaced after a period of use, the button 14 is pressed, which drives the moving rod 11 to move. This drives the gear 9 to rotate through the rack 2 10, which in turn drives the rack 1 8 to move. Then, the U-shaped locking rod 7 slides into the groove 6 at one end of the locking groove 5. One end of the U-shaped locking rod 7 disengages from the locking groove 5, and then the connecting block 3 is pulled out from the connecting groove 2. This allows for quick disassembly of the connecting block 3 and the friction pad body 4, and the operation is simple.

[0021] The U-shaped lever 7 engages with the slot 5 to fix the position of the connecting block 3.

[0022] Limiting blocks 17 are symmetrically connected on both sides of the outer wall of the connecting block 3. The inner wall of the connecting groove 2 is provided with a limiting groove 18 that is nested and slidably engaged with the limiting blocks 17. Through the sliding connection between the limiting blocks 17 and the limiting groove 18, the connecting block 3 can be stably positioned on the mounting plate 1, which can facilitate installation and also play a limiting protection role.

[0023] A cover plate 19 is movably connected inside the inner groove 13. By setting the cover plate 19, it can play a protective role in preventing accidental contact when not in use.

[0024] The above are merely preferred embodiments of this utility model patent and are not intended to limit this utility model patent. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
