Description

Technical Field

[0001] This utility model relates to the field of bicycle suspension fork technology, and in particular to an adjustable damping hydraulic suspension fork. Background Technology

[0002] The front fork is located at the front of the bicycle structure. Its upper end is connected to the handlebar assembly, the frame assembly mates with the head tube, and its lower end mates with the front axle assembly, forming the bicycle's steering system.

[0003] The prior art patent application with publication number CN218986855U describes a mechanism that uses an oil outlet adjustment mechanism. By rotating the adjustment bolt, the blocking block is moved, thereby adjusting the area of ​​the oil outlet and thus the size of the oil outlet. This allows for adjustment of the amount of hydraulic oil entering the oil tank, which can be freely adjusted according to the weight of the electric vehicle driver, thereby improving the driver's riding comfort.

[0004] However, when the adjusting bolt is turned to one side and moved to the side to move a section out of the connecting plate, the bolt is prone to loosening when the hydraulic shock absorber fork is used. This causes the size of the oil outlet to change, and the exposed section is prone to sticking to foreign objects. After the bolt is restored, the foreign objects will enter the interior of the connecting pipe and contaminate the hydraulic oil.

[0005] Therefore, it is necessary to provide an adjustable damping hydraulic shock-absorbing fork 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] First embodiment: Please refer to the following: Figures 1-4 The first embodiment of this invention provides an adjustable damping hydraulic shock-absorbing fork, which includes: a shock-absorbing device 1 and a limiting device 2; The limiting device 2 includes a support sleeve 21, a guide device 22, a sliding sleeve 23, a rotating groove 24, two rotating rods 25, two torsion springs 26, two limiting sleeves 27, and two compression sleeves 28. One end of the support sleeve 21 is fixedly connected to one end of the shock-absorbing device 1. The guide device 22 is disposed inside the support sleeve 21. The sliding sleeve 23 is slidably connected to the surface of the support sleeve 21. The rotating groove 24 is opened inside the sliding sleeve 23. Both rotating rods 25 are rotatably connected to the inside of the sliding sleeve 23. The two torsion springs 26 are respectively sleeved on the surface of the two rotating rods 25. One end of each of the two limiting sleeves 27 is fixedly connected to the surface of the two rotating rods 25. One end of each of the two compression sleeves 28 is fixedly connected to one end of each of the two limiting sleeves 27.

[0019] The shock absorber 1, through the setting of the oil outlet adjustment mechanism, rotates the adjustment bolt to drive the blocking block to move, thereby adjusting the area of ​​the oil outlet and thus adjusting the size of the oil outlet, and adjusting the amount of hydraulic oil entering the oil tank. This allows it to be freely adjusted according to the weight of the electric vehicle driver, thereby improving the driver's riding comfort.

[0020] The support sleeve 21 can be a polygonal sleeve, while the sliding sleeve 23 is a polygonal sleeve that is adapted to the support sleeve 21.

[0021] The adjusting bolt of the shock absorber 1 is threadedly connected to the inside of the support sleeve 21.

[0022] The two ends of the torsion spring 26 are fixedly connected to the inside of the limiting sleeve 27 and the sliding sleeve 23, respectively, so that the limiting sleeve 27 can be rotated to one side to a suitable position and then automatically reset after being released.

[0023] The two compression sleeves 28 are inwardly tapered, which are used to rotate and open the two limiting sleeves 27 to one side after the tool is inserted into the two compression sleeves 28.

[0024] The limiting device 2 also includes a return spring 29, which is sleeved on the surface of the support sleeve 21.

[0025] The return spring 29 is used to push the sliding sleeve 23 to move to one side, thereby limiting the adjusting bolt through the pressure of the sliding sleeve 23 moving to one side, increasing the limiting effect, and at the same time pushing the sliding sleeve 23 to move to one side to reset.

[0026] The guide device 22 includes two sliding grooves 221 and two sliding blocks 222. The two sliding grooves 221 are both opened inside the support sleeve 21, and the two sliding blocks 222 are slidably connected to the inside of the two sliding grooves 221 respectively.

[0027] The surfaces of both sliding blocks 222 are fixedly connected to the inner wall surface of the sliding sleeve 23.

[0028] When the sliding sleeve 23 slides, it drives the two sliding blocks 222 to move inside the two sliding grooves 221 respectively, thereby limiting the sliding sleeve 23.

[0029] The working principle of this first embodiment is as follows: In use, by rotating the two limiting sleeves 27 to one side, the two rotating rods 25 are rotated to one side, while the two torsion springs 26 are tightened.

[0030] By rotating the adjusting bolt of the shock absorber 1 to one side, the sliding sleeve 23 is moved on the surface of the support sleeve 21.

[0031] After adjustment, the two torsion springs 26 reset and drive the two rotating rods 25 connected to the two limiting sleeves 27 to rotate and merge to one side, thereby limiting the adjustment bolt.

[0032] Second embodiment: Please refer to the following: Figure 5 Based on the adjustable damping hydraulic shock-absorbing fork provided in the first embodiment of this application, the second embodiment of this application proposes another adjustable damping hydraulic shock-absorbing fork. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0033] Specifically, the second embodiment of this application provides an adjustable damping hydraulic shock absorber fork that also includes two sealing sleeves 3. Both sealing sleeves 3 are disposed on the surface of the shock absorber 1, and both sealing sleeves 3 are threadedly connected to a sealing cap 4 inside.

[0034] One end of the sealing sleeve 3 is fixedly connected to one end of the hydraulic rod of the shock absorption device 1.

[0035] The sealing sleeve 3 has a cleaning component 5 inside, and the sealing cover 4 has a cleaning sleeve 6 fixedly connected inside.

[0036] The cleaning sleeve 6 is used to clean impurities adhering to the surface of the hydraulic rod.

[0037] The cleaning component 5 is a cleaning cotton, which is slidably connected to the inside of the sealing sleeve 3.

[0038] The cleaning cotton is used to clean and lubricate the surface of the hydraulic rod when it absorbs lubricating oil and the hydraulic rod of the shock absorber 1 retracts.

[0039] The working principle of this second embodiment is as follows: During use, when the shock absorber 1 retracts, the cleaning sleeve 6 cleans the debris attached to the surface of the shock absorber 1, while the cleaning component 5 lubricates the surface of the shock absorber 1, thereby preventing debris from adhering to the surface of the shock absorber 1, causing scratches, etc., and increasing its service life.

[0040] 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.
