Description

Technical Field

[0001] This utility model relates to the field of bicycle shock absorber technology, and in particular to an adjustable pressure bicycle shock absorber. Background Technology

[0002] Bicycle shock absorbers are devices used to reduce vibration and bumps during riding. They can absorb road impacts and improve riding comfort and safety. Shock absorbers are divided into front shock absorbers and rear shock absorbers according to their position. Some bicycles have both. Their performance is related to spring stiffness, damping system, etc., and proper design can effectively improve the shock absorption effect.

[0003] However, heavier cyclists may experience excessive weight loss and power loss due to overly soft shock absorbers, which affects pedaling efficiency. On the other hand, lighter cyclists may experience a bumpy ride due to overly stiff shock absorbers that cannot effectively filter vibrations. Furthermore, when faced with complex and varied road conditions, a fixed shock absorber pressure may not be able to adapt to different impact intensities. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where heavier riders may experience excessive weight loss and power dissipation due to overly soft shock absorbers, affecting pedaling efficiency, while lighter riders may experience a bumpy ride due to overly stiff shock absorbers that fail to effectively filter vibrations. Furthermore, the fixed shock absorber pressure is difficult to adapt to different impact intensities when facing complex and varied road conditions. Therefore, this invention proposes an adjustable pressure bicycle shock absorber.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable pressure bicycle shock absorber, comprising a main rod, a hydraulic rod, a hollow tube, a spring, and an adjustment device. The hydraulic rod is fixed to the lower surface of the main rod, the hollow tube is sleeved with the hydraulic rod, the spring is sleeved on the surface of the main rod, and the adjustment device is located at one end of the hollow tube. The adjustment device includes a disc, which is fixed to one end of the hollow tube and communicates with it. A through hole is formed on the surface of the disc, and a retainer is fixedly connected to the surface of the disc. A turntable is rotatably connected to the surface of the retainer, and the turntable fits against the disc. A circular hole is formed on the surface of the turntable, and the circular hole on the surface of the turntable matches the through hole. A sealing plug is fixedly connected to the end of the hydraulic rod near the hollow tube. By setting the adjustment device, rotating the threaded rod adjusts the tightness between the resistance ring and the turntable, thereby rotating the turntable to change the size of the through hole, achieving flexible adjustment of air pressure to meet different pressure requirements. After adjustment, the set state can be stably maintained, ensuring that the shock absorption effect is adaptable to different scenarios.

[0006] Preferably, a resistance ring is fitted on the surface of the sleeve, and a crossbar is fixedly connected to the surface of the resistance ring. By setting the resistance ring, after the turntable is adjusted to a suitable position, friction is generated by the resistance ring against the turntable, which restricts the rotation of the turntable, thereby fixing the size of the through hole, maintaining the adjusted air pressure state, ensuring the stability of the shock absorber pressure, and avoiding pressure changes caused by the turntable shifting due to vibration or other factors.

[0007] Preferably, the surface of the sleeve has a strip-shaped hole, and the crossbar is slidably connected to the strip-shaped hole on the surface of the sleeve.

[0008] Preferably, the surface of the crossbar is rotatably connected to a threaded rod, the inner wall of the ferrule is threaded, and the threaded rod is threadedly connected to the ferrule. By setting the threaded rod, rotation drives the resistance ring to move, thereby locking and unlocking the turntable, thus fixing or allowing adjustment of the turntable position to complete pressure regulation and maintain the regulated state.

[0009] Preferably, the turntable has a locking tooth at one end near the resistance ring, and the resistance ring engages with the locking tooth on the surface of the turntable. By setting the resistance ring, after the turntable is adjusted to a suitable position, friction is generated by the resistance ring against the turntable, which restricts the movement of the turntable, thereby fixing the size of the through hole, maintaining the adjusted air pressure state, and ensuring the stability of the shock absorber pressure.

[0010] Preferably, the surface of the main rod is provided with a dustproof component, which includes a cloth sleeve. One end of the cloth sleeve is fixedly connected to the empty pipe, and the cloth sleeve is fitted onto the surface of the spring. The end of the cloth sleeve away from the empty pipe is fixedly connected to a hook. By setting up the dustproof component, the cloth sleeve protects the spring when the equipment is in use, effectively reducing the situation where sand and gravel get stuck on the spring, and reducing the impact of sand and gravel on the spring's shock absorption effect. At the same time, the cloth sleeve is connected to the retaining ring through the hook, which facilitates quick disassembly and stacking during maintenance without affecting maintenance operations, thereby improving the practicality and service life of the equipment.

[0011] Preferably, one end of the main rod is fixedly connected to a retaining ring, the hook is arranged in an "L" shape, there are two hooks, the two hooks are arranged symmetrically, and the hooks are engaged with the retaining ring.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting an adjustment device, when pressure adjustment is needed, rotating the threaded rod causes the resistance ring to move away from the turntable. At this time, rotating the turntable adjusts the size of the through hole. When the through hole narrows, the hydraulic rod drives the sealing plug to squeeze the air in the empty pipe. The air passage efficiency is poor when the through hole is small, so the air pressure increases. When the through hole is large, the air passes through quickly, and the air pressure decreases. When the turntable is adjusted to the appropriate position, rotating the threaded rod causes the resistance ring to abut against the turntable, making the turntable difficult to move. By setting an adjustment device, rotating the threaded rod adjusts the abutment state between the resistance ring and the turntable, thereby rotating the turntable to change the size of the through hole, realizing flexible adjustment of air pressure to meet different pressure requirements. Moreover, after adjustment, it can stably maintain the set state, ensuring that the shock absorption effect is suitable for different scenarios.

[0013] In this invention, by incorporating a dustproof component, the entire equipment is covered with a cloth cover during use, and hooks and clasps are used for attachment. The cloth cover protects the springs, reducing the likelihood of sand and gravel getting stuck and affecting the shock absorption effect. When maintenance is required, the hooks are released from the clasps, allowing the cloth cover to be stacked. This dustproof component, using the cloth cover to protect the springs during use, effectively reduces the likelihood of sand and gravel getting stuck, minimizing the impact on shock absorption. Furthermore, the connection between the cloth cover and the clasps facilitates quick disassembly and stacking during maintenance, without hindering the maintenance process, thus improving the practicality and lifespan of the equipment.

[0016] Please see Figures 1-5This utility model provides a technical solution: an adjustable pressure bicycle shock absorber, including a main rod 1, a hydraulic rod 2, a hollow tube 3, a spring 4 and an adjustment device 5. The hydraulic rod 2 is fixed to the lower surface of the main rod 1, the hollow tube 3 is sleeved with the hydraulic rod 2, the spring 4 is sleeved on the surface of the main rod 1, and the adjustment device 5 is set at one end of the hollow tube 3.

[0017] In this implementation scheme: the adjusting device 5 includes a disc 52, which is fixed to one end of the empty tube 3 and is connected to the empty tube 3. The disc 52 has a through hole 54 on its surface. A retainer 56 is fixedly connected to the surface of the disc 52. A turntable 53 is rotatably connected to the surface of the retainer 56. The turntable 53 fits against the disc 52. A circular hole is opened on the surface of the turntable 53, which matches the through hole 54. A sealing plug 51 is fixedly connected to one end of the hydraulic rod 2 near the empty tube 3. By setting the adjusting device 5, the threaded rod 57 is rotated to adjust the tightness between the resistance ring 58 and the turntable 53. Then, the turntable 53 is rotated to change the size of the through hole 54, so as to realize the flexible adjustment of air pressure to meet different pressure requirements. After adjustment, the set state can be stably maintained to ensure that the shock absorption effect is adapted to different scenarios.

[0018] Specifically, a resistance ring 58 is fitted on the surface of the sleeve 56, and a crossbar 59 is fixedly connected to the surface of the resistance ring 58. By setting the resistance ring 58, after the turntable 53 is adjusted to a suitable position, friction is generated by the resistance ring 58 against the turntable 53, which restricts the rotation of the turntable 53, thereby fixing the size of the through hole 54, maintaining the adjusted air pressure state, ensuring the stability of the shock absorber pressure, and avoiding pressure changes caused by the displacement of the turntable 53 due to vibration or other factors.

[0019] Specifically, the surface of the sleeve 56 has a strip-shaped hole, and the crossbar 59 is slidably connected to the strip-shaped hole on the surface of the sleeve 56.

[0020] Specifically, a threaded rod 57 is rotatably connected to the surface of the crossbar 59, and the inner wall of the ferrule 56 is threaded. The threaded rod 57 is threadedly connected to the ferrule 56. By setting the threaded rod 57, the rotation drives the resistance ring 58 to move, thereby locking and unlocking the turntable 53, thus fixing or allowing the position of the turntable 53 to be adjusted, so as to complete the pressure adjustment and maintain the adjusted state.

[0021] Specifically, the turntable 53 has a locking tooth at one end near the resistance ring 58, and the resistance ring 58 engages with the locking tooth on the surface of the turntable 53.

[0022] In this embodiment: by setting a resistance ring 58, after the turntable 53 is adjusted to a suitable position, the friction generated by the ring against the turntable 53 restricts the movement of the turntable 53, thereby fixing the size of the through hole 54, maintaining the adjusted air pressure state, and ensuring the stability of the shock absorber pressure.

[0023] Specifically, the surface of the main rod 1 is provided with a dustproof component 55, which includes a cloth cover 551. One end of the cloth cover 551 is fixedly connected to the empty tube 3. The cloth cover 551 is sleeved on the surface of the spring 4. The end of the cloth cover 551 away from the empty tube 3 is fixedly connected with a hook 552.

[0024] In this embodiment: by setting up a dustproof component 55, the protective spring 4 is covered with a cloth cover 551 when the equipment is in use, which effectively reduces the situation where sand and gravel get stuck on the spring 4, and reduces the impact of sand and gravel on the shock absorption effect of the spring 4. At the same time, the cloth cover 551 is connected to the retaining ring 553 through the hook 552, which facilitates quick disassembly and stacking during maintenance without affecting maintenance operations, thereby improving the practicality and service life of the equipment.

[0025] Specifically, one end of the main rod 1 is fixedly connected to a retaining ring 553, and the hook 552 is set in an "L" shape. There are two hooks 552, which are symmetrically arranged and are engaged with the retaining ring 553.

[0026] Working principle: By setting the adjustment device 5, when pressure adjustment is required, the threaded rod 57 is rotated. The threaded rod 57 drives the resistance ring 58 away from the turntable 53. At this time, the size of the through hole 54 is adjusted by rotating the turntable 53. When the through hole 54 narrows, the hydraulic rod 2 drives the sealing plug 51 to squeeze the air in the empty pipe 3. The air passage efficiency is poor when the through hole 54 is small, so the air pressure increases. When the through hole 54 is large, the air passes through quickly, and the air pressure decreases. When the turntable 53 is adjusted to the appropriate position, the threaded rod 57 is rotated. The threaded rod 57 drives the resistance ring 58 to abut against the turntable 53, making it difficult for the turntable 53 to move. By setting the adjustment device 5, the threaded rod 57 is rotated to adjust the tightness between the resistance ring 58 and the turntable 53, and then the turntable 53 is rotated to change the size of the through hole 54, so as to realize the flexible adjustment of air pressure to meet different pressure requirements. After adjustment, it can be stably maintained in the set state to ensure that the shock absorption effect is suitable for different scenarios. By setting up the dustproof component 55, the entire equipment is covered by the cloth cover 551 during use, and hooks 552 and retaining rings 553 are used for attachment. At this time, the cloth cover 551 protects the spring 4, reducing the possibility of sand and gravel getting stuck on the spring 4 and affecting the shock absorption effect. When maintenance is required, the hooks 552 are released from the retaining rings 553, and the cloth covers 551 can be stacked. By setting up the dustproof component 55, the cloth cover 551 is used to protect the spring 4 during equipment use, effectively reducing the possibility of sand and gravel getting stuck on the spring 4 and reducing the impact of sand and gravel on the shock absorption effect. At the same time, the cloth cover 551 is connected to the retaining rings 553 through the hooks 552, which facilitates quick disassembly and stacking during maintenance without affecting maintenance operations, thus improving the practicality and service life of the equipment.
