[0002] The bicycle front fork is located at the front of the bicycle. The upper end of the front fork is connected to the handlebars, and the lower end of the front fork is connected to the front axle, forming the bicycle's steering system.

[0003] The existing front fork is formed by connecting a lower leg for assembling the front wheel and a fork stem with a handlebar mounted horizontally at the top. The lower leg has two opposing inner tubes and fork legs that slide relative to the inner tubes. The fork legs are used to assemble the fork legs together at both ends of one axle of the front wheel. An elastic shock absorber is supported between the inner tubes and the fork legs to generate a shock-absorbing effect. This allows the front fork and the front wheel to reduce relative reciprocating vibration, thereby reducing the impact on the handlebars, avoiding discomfort to the rider's hands, and improving its controllability.

[0004] Existing shock-absorbing forks generally have a fixed shock absorption effect, making it inconvenient to flexibly adjust the preload of the shock-absorbing springs according to different road conditions (such as flat roads or bumpy mountain roads), which reduces riding comfort under complex road conditions. At the same time, shock-absorbing forks require manual lubrication periodically to reduce friction wear between components, but the manual lubrication process is very cumbersome.

[0005] Therefore, it is necessary to provide a bicycle shock-absorbing fork sliding sleeve assembly to solve the above-mentioned technical problems. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figures 1-6 This utility model provides a bicycle shock-absorbing front fork sliding sleeve assembly, including: a front fork stem 1, a connecting frame 2, and a front fork sleeve 5. The bottom of the front fork stem 1 is provided with a protective sleeve 3 and is fixedly connected to the connecting frame 2. The lower sides of both ends of the connecting frame 2 are fixedly connected with front fork sliding sleeves 4. The front fork sleeve 5 is slidably connected to the front fork sliding sleeve 4. The lower end of the front fork sliding sleeve 4 is fixedly connected with a sliding sealing seat 6. The front fork sleeve 5 is slidably connected to the sliding sealing seat 6. The front fork sliding sleeve 4 is provided with a first adjusting part 7 and a second adjusting part 8. The second adjusting part 8 is located below the first adjusting part 7 and is fixedly connected to the front fork sleeve 5. A lubrication part 9 is also provided above the front fork sleeve 5. In use, the first adjustment part 7 can be adjusted according to the shock absorption adaptation requirements of different road conditions, so that the second adjustment part 8 can be changed, thereby changing the preload of the second circular plate 82 on the shock absorption spring 85 and realizing the adjustment of the shock absorption stroke and capacity. While completing the shock absorption operation, the lubrication part 9 uses the shock absorption operation of each component to discharge the lubricating medium and cover the sliding mating surface below, so that the lubrication work does not need to be completed manually.

[0019] The fork support 5 includes a main body 51, a sliding block 52 on the outer side of the main body 51, and a top plate 53 fixedly connected to the top of the main body 51. An oil outlet 54 is opened on the outer side of the top plate 53. The oil outlet 54 at the top of the top plate 53, together with the lubrication part 9, serves as an output channel for the lubricating medium, providing continuous lubrication to the sliding mating surfaces and reducing friction wear on various components.

[0020] The sliding closure 6 includes an annular body 61, with a closing ring 62 fixedly connected to the top of the annular body 61. A sliding groove 63 is formed on the inner side of the annular body 61, and a sliding block 52 is slidably connected to the sliding groove 63. The sliding groove 63 on the inner side of the annular body 61 is adapted to the sliding block 52, which enhances the stability of the fork sleeve 5 during sliding, guides the sliding direction of the main rod 51 and limits the sliding distance, thereby controlling the sliding path of the fork sleeve 5 and ensuring the smoothness of the fork's shock absorption operation.

[0021] The first adjustment part 7 includes a lifting adjustment screw 71 and a base 73. The lifting adjustment screw 71 passes through both ends of the connecting frame 2 and extends above it. A rotating wheel 72 is fixedly connected to the upper end of the lifting adjustment screw 71. The base 73 is fixedly connected to the lower surfaces of both ends of the connecting frame 2, and a sliding rod assembly 74 is fixedly connected to the base 73. By rotating the rotating wheel 72, the lifting adjustment screw 71 is rotated, thereby adjusting the relative position of the second adjustment part 8 and realizing the adjustment of the shock absorption stroke to adapt to the user's shock absorption needs under different road conditions. The sliding rod assembly 74 on the base 73 increases the stability of the second adjustment part 8 after installation.

[0022] The second adjustment section 8 includes a first circular plate 81 and a second circular plate 82. A mating sleeve assembly 82 is fixedly connected between the first circular plate 81 and the second circular plate 82. A passage 84 is opened in the middle of the first circular plate 81. A shock-absorbing spring 85 is fixedly connected to the lower part of the second circular plate 82, and the other end of the shock-absorbing spring 85 is fixedly connected to the top plate 53. The mating sleeve assembly 82 corresponds to the sliding rod assembly 74. When the lifting adjustment screw 71 rotates, the first circular plate 81 and the second circular plate 82 move along the sliding rod assembly 74, thereby changing the preload of the second circular plate 82 on the shock-absorbing spring 85 to adapt to the user's shock absorption needs under different road conditions.

[0023] The lubrication section 9 includes a rigid tube 91 and an annular oil reservoir 93. The lower end of the rigid tube 91 is fixedly connected to the top plate 53. The lower end of the rigid tube 91 is provided with evenly distributed oil drain grooves 92. The rigid tube 91 passes through the through port 85. The annular oil reservoir 93 is set on the first circular plate 81. An oil storage cotton 94 is provided inside the annular oil reservoir 93. A fixing plate 95 is fixedly connected to the upper end of the rigid tube 91. A pressing rod 96 is fixedly connected to the fixing plate 95. The upper end of the pressing rod 96 extends into the interior of the annular oil reservoir 93 and is located below the oil storage cotton 94. An oil outlet pipe 97 is provided at the end of the annular oil reservoir 93 away from the pressing rod 96. The lower end of the oil outlet pipe 97 is connected to the side of the rigid tube 91. When the lubricating medium enters the rigid tube 91, it can flow through the drain groove 92 through the top plate 53 until it completely covers the area below that needs lubrication from the oil outlet 54, thus improving the lubrication effect. The port 84 provides installation and movement space for the rigid tube 91, while the oil reservoir 94 can store a sufficient amount of lubricating medium, eliminating the need for frequent refilling. When the fork performs vibration damping operation, the relative movement of the top plate 53 can drive the rigid tube 91 and the squeeze rod 96 to move upward and squeeze the oil reservoir 94, causing the lubricating medium in the oil reservoir 94 to continuously seep out. The lubricating medium is then transported to the rigid tube 91 for discharge through the oil outlet 97.

[0024] An oil filling pipe 98 is fixedly connected to the upper end of the annular oil reservoir 93. The upper end of the oil filling pipe 98 extends above the connecting frame 2, and a sealing plug 99 is provided at the upper end of the oil filling pipe 98. The oil filling pipe 98 extends above the connecting frame 2, allowing oil filling operations to be performed from above the connecting frame 2. The sealing plug 99 prevents the lubricating medium in the annular oil reservoir 93 from evaporating, while also preventing external dust and impurities from entering the oil filling pipe 98.

[0025] The working principle of this utility model is as follows: In use, the first adjustment part 7 can be adjusted according to the shock absorption adaptation requirements of different road conditions, so that the second adjustment part 8 can be changed, thereby changing the preload of the second circular plate 82 on the shock absorption spring 85 and realizing the adjustment of the shock absorption stroke and capacity. While completing the shock absorption operation, the lubrication part 9 uses the shock absorption operation of each component to discharge the lubricating medium and cover the sliding mating surface below, so that the lubrication work does not need to be completed manually.

[0026] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
