Description

Technical Field

[0001] This utility model relates to the technical field of oil filling devices, and in particular to an oil filling device for assembling shock absorber forks. Background Technology

[0002] The suspension fork is a key component of the suspension system in bicycles and motorcycles. It mainly consists of an inner tube, an outer tube, a piston, and damping oil. The piston's movement within the damping oil generates damping force, achieving shock absorption and cushioning. During assembly, filling the fork with damping oil is a crucial step to ensure its proper functioning, directly affecting its shock absorption performance and riding comfort. Different models and specifications of suspension forks have strict requirements regarding the quantity, quality, and uniformity of the damping oil. Mountain bike suspension forks require precise damping control under complex road conditions; too much or too little oil will lead to poor shock absorption or even damage to the fork components. Road bike suspension forks, on the other hand, prioritize the uniformity of the damping oil to ensure a smooth ride.

[0003] The oil filling device for suspension forks mainly consists of an oil reservoir and support and positioning components. The normal operation of a suspension fork depends on the performance of the damping oil. If the damping oil contains impurities, such as tiny metal particles or dust, it will affect the normal operation of the damping system. During shock absorption, the piston reciprocates in the oil. Impurities may cause accelerated piston wear and damage to the seals, thereby affecting the shock absorption effect and service life of the suspension fork. The internal structure of the suspension fork is precise. Some small impurities may enter and block the damping holes or get stuck between the piston and the cylinder wall, causing uneven damping force or even causing the components to seize up. This will cause the suspension fork to lose its shock absorption function or produce abnormal noises, seriously affecting the comfort and safety of riding. In the assembly workshop of suspension forks, there may be a lot of dust and metal shavings in the air. These impurities can easily mix into the damping oil during the oil filling process. If the oil filling device has poor filtration, it will not be able to effectively remove these newly mixed impurities, increasing the risk of oil contamination. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an oil filling device for assembling shock-absorbing forks, aiming to improve the problem that the normal operation of shock-absorbing forks depends on the performance of damping oil, and that if the damping oil contains impurities, such as tiny metal particles or dust, it will affect the normal operation of the damping system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an oil filling device for shock-absorbing front fork assembly, comprising a filter box and a connecting sleeve plate.

[0039] Specifically, the protective pads 20 are used to protect the oil filling plate 10 from damage during operation and to provide additional safety for the user. In addition, oil filling devices 11 are fixedly connected to the bottom of the oil filling plate 10. Protective sleeves 21 are fixedly connected to the upper and lower ends of the outer wall of the connecting sleeve plate 13. These protective sleeves 21 can not only protect the outer wall of the connecting sleeve plate 13, but also extend its service life. In the design of the filter box 1, soft pads 15 are fixedly connected to the top left and right sides of its outer wall. The function of these soft pads 15 is to reduce the vibration and noise that may be generated during the transportation or movement of the filter box 1, and at the same time, it can also protect the outer wall of the filter box 1 from damage to a certain extent. Oil inlets 16 are fixedly connected to the bottom left and right sides of the outer wall of the filter box 1. These oil inlets 16 are for facilitating the input of oil and ensuring that the filter box 1 can efficiently filter oil.

[0040] Working principle: When oil enters through the oil inlets 16 installed on the left and right sides of the outer wall of the filter box 1, the sedimentation chambers 3 opened at the left and right ends of the inner wall of the filter box 1 will settle the oil. At the same time, the filter baffles 4 fixed to the inner wall of the filter box 1 have suction holes 7 on their inner walls and suction plates 6 fixed to them to absorb impurities. Meanwhile, filter holes 5 are opened on the top of the outer wall of the filter baffles 4 to filter the oil. The H-shaped filter plate 8 fixed in the middle of the inner wall of the filter box 1 has a funnel shape that can effectively filter larger impurities in the oil. At the same time, the fine filter screens 9 installed on the left and right sides of the inner wall of the H-shaped filter plate 8 can filter small impurities, thereby achieving a multi-stage filtration effect. This effectively removes impurities, particles, water and harmful substances from the oil, preventing them from entering the shock-absorbing fork and avoiding wear or corrosion of the fork's seals, pistons and other components, thus extending the service life of the fork.

[0041] To better assist in oil filling, threaded shafts 201 are threadedly connected to the left and right sides of the outer wall of the connecting sleeve 13. A fixed circular plate 202 is rotatably connected to the inner side of the threaded shaft 201. When oil filling is required, an external force rotates the rotating plate 207, which causes the threaded shaft 201 to rotate so that the extrusion plate 203 fixed at the other end of the fixed circular plate 202 can extrude and fix the inner wall. At the same time, the connecting shaft 204 fixed to the upper and lower ends of the outer wall of the extrusion plate 203 has a spring 205 installed on its outer wall, which can effectively protect it during extrusion, thereby assisting in fixing the oil filling.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
