Description

Technical Field

[0001] This utility model relates to the field of bicycle shock absorber technology, and in particular to a dual-damping bicycle shock absorber. Background Technology

[0002] Bicycle shock absorbers are an important component of bicycles. Their main function is to reduce vibration and bumps during riding, improve comfort and stability, and protect the rider's body. They are usually composed of springs and damping systems. Springs are responsible for absorbing impact forces, while the damping system controls the rebound speed. Shock absorbers are generally installed on the front or rear wheel, while full-suspension bicycles have them on both the front and rear wheels to better adapt to complex road conditions.

[0003] However, bicycle shock absorbers are prone to losing their normal function after prolonged use due to wear, aging, or damage to parts. Since they are fixed to the frame with bolts, replacement requires the use of tools to remove each bolt one by one, which is a tedious and laborious process. This is especially true when the bolts are rusty or too tight, which makes disassembly even more difficult, extending the replacement time and increasing the workload of maintenance personnel. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology of bicycle shock absorbers, which are prone to losing normal function due to wear, aging or damage of parts after long-term use. In addition, since they are fixed to the frame with bolts, replacement requires the use of tools to remove the bolts one by one, which is a tedious and laborious process. Especially when the bolts are rusty or too tight, the disassembly is even more difficult, which not only prolongs the replacement time but also increases the workload of maintenance personnel. Therefore, a dual-damping bicycle shock absorber is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a dual-damping bicycle shock absorber, comprising a frame, a vertical pole, a shock-absorbing device, an assembly plate, and a replacement device. The vertical pole is fixed to the lower surface of the frame, the shock-absorbing device is installed below the vertical pole, the upper surface of the frame is provided with an assembly plate, and the replacement device is disposed on the surface of the assembly plate. The replacement device includes a plug rod, which is fixedly connected to the frame. The inner wall of the plug rod is hollow, and a rotating rod is fixedly connected to the inner wall of the plug rod. A bending rod is rotatably connected to the surface of the rotating rod. A baffle is fixedly connected to the upper surface of the assembly plate. A circular hole is opened on the surface of the assembly plate, and the insertion rod is inserted into the circular hole on the surface of the assembly plate. A through hole is opened on the surface of the baffle, and the bending rod is inserted into the through hole on the surface of the baffle. By setting a replacement device, the equipment can be quickly disassembled and installed. Squeezing the push plate can make the bending rod detach from the baffle and remove the equipment. After inserting the insertion rod, releasing the push plate will allow the bending rod to be inserted into the baffle by the spring force to complete the fixation. No tools are needed, which simplifies the replacement process, saves replacement time, reduces replacement difficulty, and reduces additional damage caused by improper disassembly.

[0006] Preferably, a push plate is fixedly connected to the upper surface of the bending rod. The bending rod is L-shaped. By setting the bending rod, the device can be fixed and unlocked in conjunction with the baffle. When the push plate is squeezed, it is driven to disengage from the baffle so that the device can be removed. When the push plate is released, it is inserted into the baffle under the action of the spring force, fixing the device on the assembly plate and ensuring that the device is installed stably.

[0007] Preferably, a spring is fixedly connected to the inner wall of the insertion rod, and the end of the spring away from the insertion rod is fixedly connected to the bending rod. By setting the spring, when the push plate is released, the spring loses its restraint and generates elastic force to squeeze the bending rod, causing the bending rod to insert into the baffle, thereby firmly fixing the equipment and ensuring the stability of the equipment after installation.

[0008] Preferably, there are two insertion rods, which are symmetrically arranged. By setting the insertion rods, they are inserted into the assembly plate during equipment installation to play a positioning and guiding role, ensuring accurate docking between the frame and the assembly plate. This also facilitates the smooth insertion of the bending rod into the baffle under the action of the spring force to complete the fixation, ensuring the stability and accuracy of equipment installation.

[0009] Preferably, the surface of the shock absorber is provided with a protective component. The protective component includes a first retainer, which is fixedly connected to the shock absorber. A second retainer is fixedly connected to one end of the shock absorber near the first retainer. The surface of the second retainer has a groove. The first retainer and the groove on the surface of the second retainer are slidably connected. By providing the protective component, when the shock absorber is working, the cooperation of the first and second retainers allows the first retainer to be inserted into the second retainer by moving along the slide rail via a wheel when the shock absorber is deformed by compression. When resetting, both retainers extend out to protect the shock absorber, effectively reducing interference from external mud and sand, protecting the internal structure of the shock absorber, and extending its service life.

[0010] Preferably, a slide rail is fixedly connected to the surface of the second ferrule, and a wheel is rotatably connected to one end of the first ferrule. By setting the wheel, the first ferrule can slide smoothly along the slide rail when it moves, reducing the frictional resistance between the first ferrule and the slide rail. This allows the first ferrule to move flexibly and smoothly insert into the second ferrule when it is squeezed and deformed by the shock-absorbing device, ensuring the normal operation of the protective components and ensuring effective protection of the shock-absorbing device.

[0011] Preferably, the wheel is located in the inner wall of the slide rail, and the first and second ferrules cover the shock absorption device.

[0012] Preferably, there are two slide rails, which are symmetrically arranged. By setting the slide rails, the equipment can be quickly disassembled and installed. The equipment can be removed by squeezing the push plate to make the bending rod disengage from the baffle. After inserting the rod, the push plate is released and the bending rod is inserted into the baffle by the spring force to complete the fixation. No tools are required, which simplifies the replacement process, saves time, and reduces the difficulty of replacement.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting a replacement device, when the equipment needs to be disassembled and replaced, squeezing the push plate causes the bending rod to disengage from the baffle. Subsequently, the frame is pulled apart from the assembly plate, allowing the entire equipment to be removed. The insertion rod is then inserted into the assembly plate. After releasing the push plate, the spring, no longer restrained, generates elastic force to press the bending rod into the baffle, completing the fixation. By setting a replacement device, the equipment can be quickly disassembled and installed. Squeezing the push plate allows the bending rod to disengage from the baffle and remove the equipment. After inserting the insertion rod, releasing the push plate allows the spring force to insert the bending rod into the baffle, completing the fixation. No tools are needed, simplifying the replacement process, saving replacement time, reducing replacement difficulty, and minimizing additional damage caused by improper disassembly.

[0015] In this invention, by setting up a protective component, during use, when the shock-absorbing device is compressed and deformed, the first ferrule moves along the slide rail with the cooperation of the wheel, and at the same time, the first ferrule inserts into the second ferrule. When the shock-absorbing device returns to its original position, the first and second ferrules extend out, thus covering and protecting the entire shock-absorbing device, reducing interference from external mud and sand. By setting up the protective component, when the shock-absorbing device is working, the cooperation of the first and second ferrules allows the wheel to move along the slide rail and the first ferrule to insert into the second ferrule when the shock-absorbing device is compressed and deformed. When it returns to its original position, both extend out to cover and protect the shock-absorbing device, effectively reducing interference from external mud and sand, protecting the internal structure of the shock-absorbing device, and extending its service life.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a dual-damping bicycle shock absorber, including a frame 1, a pole 2, a shock-absorbing device 3, an assembly plate 4, and a replacement device 5. The pole 2 is fixed to the lower surface of the frame 1, the shock-absorbing device 3 is installed below the pole 2, the upper surface of the frame 1 is provided with the assembly plate 4, and the replacement device 5 is provided on the surface of the assembly plate 4.

[0023] In this implementation scheme: the replacement device 5 includes a rod 51, which is fixedly connected to the frame 1. The inner wall of the rod 51 is hollow, and a rotating rod 58 is fixedly connected to the inner wall of the rod 51. A bending rod 53 is rotatably connected to the surface of the rotating rod 58. A baffle 54 is fixedly connected to the upper surface of the assembly plate 4. A round hole is opened on the surface of the assembly plate 4, and the rod 51 is inserted into the round hole on the surface of the assembly plate 4. A through hole 55 is opened on the surface of the baffle 54, and the bending rod 53 is inserted into the through hole 55 on the surface of the baffle 54. By setting the replacement device 5, the equipment can be quickly disassembled and installed. Squeezing the push plate 52 can make the bending rod 53 disengage from the baffle 54 and remove the equipment. After inserting the rod 51, releasing the push plate 52 allows the bending rod 53 to be inserted into the baffle 54 by the elastic force of the spring 57 to complete the fixation. No tools are needed, which simplifies the replacement process, saves replacement time, reduces replacement difficulty, and reduces additional damage caused by improper disassembly.

[0024] Specifically, a push plate 52 is fixedly connected to the upper surface of the bending rod 53. The bending rod 53 is set in an "L" shape. By setting the bending rod 53, the device can be fixed and unlocked in conjunction with the baffle 54. When the push plate 52 is squeezed, it is driven to disengage from the baffle 54 so that the device can be removed. When the push plate 52 is released, it is inserted into the baffle 54 under the elastic force of the spring 57, fixing the device on the assembly plate 4 and ensuring that the device is installed stably.

[0025] Specifically, a spring 57 is fixedly connected to the inner wall of the insertion rod 51. The end of the spring 57 away from the insertion rod 51 is fixedly connected to the bending rod 53. By setting the spring 57, when the push plate 52 is released, the spring 57 loses its restraint and generates elastic force to squeeze the bending rod 53, so that the bending rod 53 is inserted into the baffle 54, thereby firmly fixing the equipment and ensuring the stability of the equipment after installation.

[0026] Specifically, there are two insertion rods 51, which are symmetrically arranged. By setting the insertion rods 51, they are inserted into the assembly plate 4 during equipment installation to play a positioning and guiding role, ensuring that the frame 1 and the assembly plate 4 are accurately connected, and facilitating the smooth insertion of the bending rod 53 into the baffle 54 under the elastic force of the spring 57 to complete the fixation, thus ensuring the stability and accuracy of equipment installation.

[0027] Specifically, the surface of the shock absorber 3 is provided with a protective component 56. The protective component 56 includes a first retainer 561, which is fixedly connected to the shock absorber 3. A second retainer 562 is fixedly connected to one end of the shock absorber 3 near the first retainer 561. The surface of the second retainer 562 has a groove. The first retainer 561 and the groove on the surface of the second retainer 562 are slidably connected. By setting the protective component 56, when the shock absorber 3 is working, the cooperation of the first retainer 561 and the second retainer 562 allows the shock absorber 3 to move along the slide rail 563 via the wheel 564 when it is squeezed and deformed, so that the first retainer 561 can be inserted into the second retainer 562. When resetting, both retainers extend out to protect the shock absorber 3, effectively reducing the interference of external mud and sand, protecting the internal structure of the shock absorber 3, and extending its service life.

[0028] Specifically, a slide rail 563 is fixedly connected to the surface of the second ferrule 562, and a wheel 564 is rotatably connected to one end of the first ferrule 561.

[0029] In this embodiment: when the first ferrule 561 moves, it slides smoothly along the slide rail 563, reducing the frictional resistance between the first ferrule 561 and the slide rail 563, so that the first ferrule 561 can move flexibly and smoothly insert into the second ferrule 562 when the shock absorber 3 is squeezed and deformed, ensuring the normal operation of the protective component 56 and ensuring effective protection of the shock absorber 3.

[0030] Specifically, the wheel 564 is located in the inner wall of the slide rail 563, and the first ferrule 561 and the second ferrule 562 fit the shock absorption device 3.

[0031] Specifically, there are two slide rails 563, which are arranged symmetrically.

[0032] In this embodiment: by setting the slide rail 563, the device can be quickly disassembled and installed. The device can be removed by squeezing the push plate 52 to make the bending rod 53 disengage from the baffle 54. After inserting the insertion rod 51, the push plate 52 is released and the bending rod 53 is inserted into the baffle 54 by the elastic force of the spring 57 to complete the fixation. No tools are required, which simplifies the replacement process, saves time, and reduces the difficulty of replacement.

[0033] Working principle: By setting up the replacement device 5, when the equipment needs to be disassembled and replaced, the push plate 52 is squeezed, and the push plate 52 drives the bending rod 53 to disengage from the baffle 54. Then, the frame 1 is pulled to separate from the assembly plate 4, and the whole equipment can be removed. The insertion rod 51 is inserted into the assembly plate 4, and then the push plate 52 is released. The spring 57 loses its restraint and generates elastic force to squeeze the bending rod 53 into the baffle 54 to complete the fixation. By setting up the replacement device 5, the equipment can be quickly disassembled and installed. Squeezing the push plate 52 can make the bending rod 53 disengage from the baffle 54 to remove the equipment. After inserting the insertion rod 51, the push plate 52 is released, and the elastic force of the spring 57 makes the bending rod 53 insert into the baffle 54 to complete the fixation. No tools are needed, which simplifies the replacement process, saves replacement time, reduces replacement difficulty, and reduces additional damage caused by improper disassembly.

[0034] By setting the protective component 56, when the shock absorber 3 is deformed by compression during use, the first ferrule 561 moves along the slide rail 563 with the cooperation of the wheel 564. At the same time, the first ferrule 561 inserts into the second ferrule 562. When the shock absorber 3 is reset, the first ferrule 561 and the second ferrule 562 extend out, covering and protecting the entire shock absorber 3, reducing interference from external mud and sand. By setting the protective component 56, when the shock absorber 3 is working, the cooperation of the first ferrule 561 and the second ferrule 562 allows the first ferrule 561 to insert into the second ferrule 562 by moving along the slide rail 563 with the wheel 564 when the shock absorber 3 is deformed by compression. When the shock absorber 3 is reset, both extend out to cover and protect the shock absorber 3, effectively reducing interference from external mud and sand, protecting the internal structure of the shock absorber 3, and extending its service life.
