[0024] Embodiment 1:

[0025] The adjustable damping shaft structure provided by the utility model is preferably implemented as follows: Figures 1 to 5 As shown: an adjustable damping shaft structure, comprising a fixed member 1 and a rotating member 3, a fixed seat 2 is fixedly mounted on the front of the fixed member 1, a rotating shaft 4 is fixedly mounted on the inner wall of the fixed seat 2, the rotating member 3 is movably sleeved on the outer wall of the rotating shaft 4, and adjustable damping mechanisms 5 are arranged on both sides of the fixed seat 2;

[0026] The adjustable damping mechanism 5 includes a screw rod 503, a pressure plate 504 and an annular plate 507.

A pressure plate 504 is fixedly installed on the inner side of the pressure plate 501. An annular groove 506 is provided on one side of the rotating member 3. The annular plate 507 is slidably connected to the inner wall of the annular groove 506. The pressure plate 504 penetrates one side of the fixed seat 2 and extends into the interior of the annular groove 506. One end of the pressure plate 504 is in contact with the outer surface of the annular plate 507. A limiting rod 508 is fixedly installed on the inner side of the annular plate 507. A rod groove 510 is provided on the inner wall of the annular groove 506. The limiting rod 508 is inserted into the rod groove 510.

The spring 509 is fixedly installed between the inner side of the annular plate 507 and the inner wall of the annular groove 506.

[0027] The above technical solution is specifically that when the adjustable damping shaft 4 structure is in use, the rotating plate 502 can be rotated, and the rotating plate 502 drives the screw 503 to rotate, and the screw 503 drives the pressure plate 501 to move toward the fixed seat 2, and drives the pressure plate 504 to move into the annular groove 506, so that the pressure plate 504 squeezes the annular plate 507, and the annular plate 507 compresses the spring 509, so that the reaction force of the spring 509 is increased, and the friction between the pressure plate 504 and the annular plate 507 is increased, so that the damping force generated when the rotating member 3 drives the annular plate 507 to rotate is increased, so that the rotating member 3 is more stable when fixed at a specified angle. Through this mechanism, it is convenient for personnel to adjust the damping size between the rotating member 3 and the fixed seat 2, so as to facilitate the flexible rotation angle of the rotating member 3, and solves the problem that the damping size of the existing shaft 4 structure is fixed, and it is difficult to adjust the damping size according to the force size of the rotating member 3, so that it is inconvenient to apply to applications with different intensities and has high limitations in use.

[0028] Furthermore, there are four pressure plates 504 inside the pressure plate 501, and a plate opening 505 is opened on one side of the fixing seat 2, and the pressure plates 504 movably penetrate the plate opening 505;

[0029] Among them, by setting the plate opening 505, the pressure plate 504 can be limited to ensure the stability of the pressure plate 504 when in use.

[0030] Furthermore, the annular plate 507 is matched with the annular groove 506, and the limiting rod 508 is matched with the rod groove 510;

[0031] Among them, by setting a limiting rod 508, the annular plate 507 can be limited, thereby improving the stability of the annular plate 507 in the annular groove 506.

[0032] Furthermore, a rotating plate 502 is fixedly mounted on the other end of the screw rod 503;

[0033] Wherein, by providing the rotating plate 502, it is convenient for personnel to rotate the screw rod 503 through the rotating plate 502, thereby facilitating the operation of personnel.

[0036] Specifically, the above technical solution provides a limiting slider 6 and a limiting slot 7 to limit the rotating member 3 to a certain extent, thereby improving the stability of the rotating member 3 when rotating on the fixed seat 2. The structure is simple and the practicability is strong.

[0037] Furthermore, the number of the limiting slide block 6 and the number of the limiting slide groove 7 are both two, and the limiting slide block 6 and the limiting slide groove 7 are adapted to each other.
