[0038] Specifically, the axis lines of the threaded column 420, the fixed plate 410 and the movable plate 430 are on the same straight line.

[0039] Specifically, a rotating wheel 450 is fixedly sleeved on the outside of the threaded column 420.

[0040] Further specific description: The rotating wheel 450 is for convenient hand-held rotation, and then drives the threaded column 420 to rotate.

[0041] Specifically, rotating openings 460 are provided at the opposite ends of the fixed plate 410 and the movable plate 430, and the two ends of the threaded column 420 are respectively threadedly connected within the rotating openings 460.

[0042] Further specific description: The inner wall of the rotating opening 460 has a thread ring adapted to the outside of the threaded column 420.

[0043] Specifically, annular limiting annular grooves 470 are provided on the circumferential sides of the inner walls of the rotating openings 460. The rotating openings 460 are communicated with the limiting annular grooves 470. Limiting annular blocks 480 are fixed at both ends of the threaded column 420 inside the rotating openings 460, and the limiting annular blocks 480 are movably connected within the limiting annular grooves 470.

[0044] Further specific description: The design of the limiting annular groove 470 and the limiting annular block 480 is to limit the ends of the threaded column 420 and prevent the ends of the threaded column 420 from detaching from the fixed plate 410 or the movable plate 430 during the rotation process.

[0045] Specifically, it further includes a second adjustment assembly 500. The second adjustment assembly 500 is movably arranged at the lower end outside the cylinder body 100. The second adjustment assembly 500 is used to adjust the length of the spring 300 to achieve the effect of adjusting the damping force.

[0046] Specifically, the second adjustment component 500 includes a rotating column 510. The bottom end of the spring 300 is fixedly connected to the rotating column 510. The rotating column 510 is threadedly connected to the lower end of the cylinder 100. The rotating column 510 is sleeved on the outer lower end of the cylinder 100. There is an insertion plate 520 on the rotating column 510. One end of the insertion plate 520 passes through the rotating column 510 and is movably inserted on the cylinder 100. There is a limiting component 600 on the insertion plate 520;

[0047] A plurality of groups of slots 530 are opened up and down on the outer part of the cylinder 100. The insertion plate 520 is inserted into the inside of the slots 530. Each group of slots 530 is radially and equidistantly distributed around the axis of the cylinder 100.

[0048] Further specific description: There is a thread ring on the inner wall of the rotating column 510, and there is a threaded hole on the outer lower end of the cylinder 100. The thread ring and the threaded hole cooperate to make the rotating column 510 threadedly connected to the cylinder 100; through the design of the insertion plate 520, the rotating column 510 and the cylinder 100 can be fixedly connected together, and the insertion plate 520 is fixed by the limiting component 600, so that after the adjustment at the upper end of the spring 300 is completed, the rotating column 510 and the cylinder 100 can be stably connected.

[0049] Specifically, the limiting component 600 includes a plug rod 610 movably connected to the insertion plate 520. One end of the plug rod 610 is fixed with a threaded head 620. The other end of the threaded head 620 is screwed to the rotating column 510;

[0052] Further specific description: The outer diameter dimension of the threaded head 620 is greater than the inner diameter dimension of the insertion opening. This structural design is to prevent the threaded head 620 from slipping out of the insertion opening after the plug rod 610 is removed, that is, the threaded head 620 is separated from the slot 530.

[0053] Specifically, a first mounting plate 700 and a second mounting plate 800 are respectively fixed to the bottom end of the cylinder 100 and the top end of the movable plate 430.

[0054] Further specific description: Through the design of the first mounting plate 700 and the second mounting plate 800, the installation of the shock absorber can be facilitated.

[0055] In the actual use process of the adjustable vehicle shock absorber according to the embodiment of the present application:

[0056] When it is necessary to adapt to different vehicle chassis heights, the operation is as follows: Hold the rotating wheel 450 and turn it. The rotating wheel 450 drives the threaded column 420 to rotate. The lower end of the threaded column 420 is threadedly connected to the fixing plate 410. With the fixing plate 410 remaining stationary, the threaded column 420 moves upward. While the threaded column 420 moves upward, it drives the movable plate 430 to move upward. On the other hand, the upper end of the threaded column 420 is threadedly connected to the movable plate 430. Since the fixing plate 410 and the movable plate 430 are connected by a telescopic rod 440, the telescopic rod 440 stably limits the upward movement of the movable plate 430. The movable plate 430 further moves upward under the spiral action of the threaded column 420, thereby increasing the overall length of the shock absorber to adapt to the heights of different vehicle chassis.

[0057] When it is necessary to adjust the damping force of the shock absorber, hold the insertion rod 610 and turn it. The threaded head 620 is screwed out from the threaded port 630. Then, pull the insertion plate 520 out of the rotating column 510. Next, hold the rotating column 510 and turn it. The rotating column 510 moves upward, the length of the spring 300 decreases, and the damping force increases. Then, insert one end of the insertion plate 520 into the rotating column 510 and the cylinder body 100 in sequence. Turn the insertion rod 610 again to screw the threaded head 620 into the threaded port 630 to fix the rotating column 510 and the cylinder body 100.

[0058] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
