Abstract
Description
Technical Field
[0001] This utility model relates to the field of shock absorber knob technology, specifically a shock absorber preload adjustment knob structure. Background Technology
[0002] In the automotive industry and high-end machinery manufacturing, shock absorbers are indispensable core components. The accuracy of their preload adjustment directly determines the damping efficiency and dynamic response quality of the shock absorption system, and is closely related to the reliability of the machinery throughout its entire life cycle. Scientifically and rationally set preload adjustments can effectively reduce impact loads during equipment operation and delay component wear.
[0003] In the automotive and mechanical equipment sectors, most shock absorber preload adjustment knobs still employ a smooth surface or shallow textured design. When an operator manually turns the knob, the coefficient of friction between their fingers and the knob surface is difficult to match the resistance threshold of the preload spring. This mismatch in force transmission often leads to noticeable sticking and resistance during knob rotation, increasing operating time and costs. Furthermore, repeated force application can accelerate surface wear, affecting the durability of adjustment accuracy. Utility Model Content

[0027] Example 1
[0028] Combination Figures 1 to 4 A shock absorber preload adjustment knob structure includes a shock absorber 1, a knob 2 fixedly connected to the top of the shock absorber 1, an auxiliary mechanism 4 provided on the knob 2, and a stabilizing mechanism 3 provided on the auxiliary mechanism 4.
[0029] The auxiliary mechanism 4 includes a fixed ring 43, which is fixedly connected to the surface of the knob 2. Fixed plates 46 are fixedly connected to the left and right sides of the fixed ring 43. A T-shaped groove 44 is provided on the top of the fixed plate 46. A T-shaped block 401 is slidably connected inside the T-shaped groove 44. A sleeve 42 is fixedly connected to the top of the T-shaped block 401. A round hole groove 402 is provided inside the sleeve 42. A handle 403 is fixedly connected to the top of the sleeve 42. A connecting plate 41 is fixedly connected to the left and right sides of the sleeve 42. A connecting seat 49 is fixedly connected to the bottom of the connecting plate 41. A trapezoidal plate 48 is fixedly connected to the bottom of the connecting seat 49. Trapezoidal seats 47 are fixedly connected to both ends of the top of the fixed plate 46. A trapezoidal groove 45 is provided on the top of the fixed plate 46.
[0030] The bottom and back of the circular slot 402 are open, the surface of the knob 2 is inserted into the inside of the circular slot 402, there are two trapezoidal slots 45 and two T-shaped slots 44, the two trapezoidal slots 45 are set on the outside of the two T-shaped slots 44, the top and front of the trapezoidal slots 45 are open, the surface of the trapezoidal plate 48 is inserted into the inside of the trapezoidal slots 45, and the trapezoidal slots 45 are set between the two trapezoidal seats 47.
[0031] Furthermore, the sleeve 42 drives the T-block 401 to slide within the T-slot 44. Simultaneously, the sleeve 42 is positioned on top of the knob 2, and the trapezoidal plate 48 is driven to insert into the trapezoidal slot 45. At the same time, the trapezoidal plate 48 is positioned within the two trapezoidal seats 47, allowing the two trapezoidal inclined surfaces to contact each other. The large-size surfaces of the trapezoidal plate 48 and the trapezoidal seats 47 face opposite directions, which can fix the sleeve 42 on the knob 2. This facilitates direct rotation of the handle 403, ultimately causing the knob 2 to rotate, allowing for pressure adjustment of the shock absorber 1 as needed.
[0032] Example 2
[0033] See Figure 1-6 Furthermore, based on Embodiment 1, the stabilizing mechanism 3 includes a hinge plate 35, which is hinged to the left and right sides of the connecting seat 49. A telescopic plate 34 is hinged to the other side of the hinge plate 35. A long groove 33 is provided at the bottom of the connecting plate 41, and a slot 32 is provided at the top of the inner wall of the long groove 33. Bolts 31 are threadedly connected to the front of the telescopic plate 34 and the connecting plate 41.
[0034] There are four long slots 33, which are arranged in pairs. Two long slots 33 are set on the left and right sides of the connecting seat 49. The bottom of the long slot 33 is set as an opening. The top and bottom of the slot 32 are set as openings. The surface of the telescopic plate 34 is inserted into the inside of the slot 32.
[0035] Furthermore, the hinge plate 35 rotates on one side of the connecting seat 49, so that the telescopic plate 34 is set at the bottom of the slot 32. The telescopic plate 34 is stretched and inserted into the slot 32 again. The telescopic plate 34 and the connecting plate 41 are threadedly fixed by the bolt 31. Under the principle of triangular stability, the knob 2 can also rotate steadily when the handle 403 is rotated.
[0036] In actual operation, when this device is used and the knob 2 needs to be rotated for pressure adjustment, the sleeve 42 can be used to drive the T-shaped block 401 to slide in the T-shaped groove 44. At the same time, the sleeve 42 is set on the top of the knob 2, and the trapezoidal plate 48 is driven to be inserted into the trapezoidal groove 45. The trapezoidal plate 48 is set in the two trapezoidal seats 47, and can finally be contacted by the two trapezoidal inclined surfaces. At the same time, the large-size surfaces of the trapezoidal plate 48 and the trapezoidal seat 47 face opposite directions, which can fix the sleeve 42 on the knob 2. It is convenient to directly rotate the handle 403, which can finally make the knob 2 rotate, and facilitate the pressure adjustment of the shock absorber 1 according to the needs.
[0037] As the hinge plate 35 rotates on one side of the connecting seat 49, the telescopic plate 34 is positioned at the bottom of the slot 32. The telescopic plate 34 is then stretched and inserted into the slot 32. The telescopic plate 34 and the connecting plate 41 are threadedly fixed using bolts 31. Under the principle of triangular stability, the knob 2 can rotate steadily when the handle 403 is turned.
