[0032] By adopting the above technical solution, the first hinge plate 18 and the second hinge plate 19 form a limiting effect. When the first hinge plate 18 swings slowly, the front side of the support plate 2 is driven by the second hinge plate 19 to slowly hinge and rotate along a pair of second ear seats 11, thereby adjusting the inclination angle of the support plate 2 and the tire.

[0033] In the specific implementation process, Figure 3 and Figure 5 As shown, a horizontally placed double-axis motor 13 is provided in the middle of the top surface of the bottom plate 1, and the model of the double-axis motor 13 is D59L-2460-50.

The driving gear 15 engages to drive the driven gear 17, the driven shaft 16 and the first hinge plate 18 to swing slowly, which facilitates driving the pair of first hinge plates 18 to perform hinged swing.

[0036] It should be noted that: in the present embodiment, a semicircular notch is provided in the middle of the rear side of the support plate 2, and a single-axis motor 26 with the output end facing downward is installed inside the semicircular notch, and the model of the single-axis motor 26 is STP28D1004; the motor shaft end of the single-axis motor 26 is sleeved with a concentrically fixed driving pulley, and the bottom end of the fixed shaft 21 is sleeved with a concentrically fixed driven pulley, and the driving pulley is connected to the driven pulley through a driving belt 27;

[0037] By adopting the above technical solution, the motor shaft of the single-axis motor 26 drives the active pulley to rotate synchronously, and the active pulley drives the driven pulley, the fixed shaft 21, and the fixed disk 22 to rotate slowly through the driving belt 27, which facilitates driving the fixed disk 22 to rotate.

[0038] Embodiment 2: In Embodiment 1, there is still a problem that when the tire tilts with the tilt of the support plate 2, the tire is not firmly fixed during maintenance. Therefore, based on Embodiment 1, this embodiment also includes:

[0039] In the specific implementation process, Figure 1 and Figure 6 As shown, the clamping assembly includes an elliptical slider 24 and a connecting rod 23. Three elliptical through holes 28 are opened on the top surface of the support plate 2, and the three elliptical through holes 28 are arranged in a circle around the fixed shaft 21; a fixedly connected elliptical slider 24 is provided in the middle of the bottom surface of each arc-shaped clamping plate 25, and each elliptical slider 24 is slidably engaged in the corresponding elliptical through hole 28, and a fixedly connected connecting pin is provided in the middle of the bottom surface of each elliptical slider 24. Three movably hinged connecting rods 23 are provided on the outer edge of the top surface of the fixed plate 22, and the outer end of each connecting rod 23 is movably hinged to the corresponding connecting pin;

[0040] By adopting the above technical solution, when the fixed plate 22 rotates, the connecting rod 23 forms a limiting effect with the elliptical slider 24 through the connecting pin shaft, and the elliptical slider 24 is driven by the connecting rod 23 to slide inward synchronously along the elliptical through hole 28, thereby driving the three arc-shaped clamping plates 25 to slowly close, thereby clamping and fixing the tire, thereby enhancing the firmness of the tire fixation.

[0041] Specifically, the working principle and operation method of the utility model are as follows:

[0042] Step 1: Place the tire to be inspected between the three arc-shaped clamping plates 25, and start the single-axis motor 26. The motor shaft of the single-axis motor 26 drives the driving pulley to rotate synchronously, and the driving pulley drives the driven pulley, the fixed shaft 21, and the fixed disk 22 to rotate slowly through the driving belt 27;

[0043] Step 2: When the fixing plate 22 rotates, the connecting rod 23 forms a limiting effect with the elliptical slider 24 through the connecting pin, and the elliptical slider 24 is driven by the connecting rod 23 to slide inward along the elliptical through hole 28 synchronously, thereby driving the three arc-shaped clamping plates 25 to slowly close, thereby clamping and fixing the tire;

[0044] Step 3, start the dual-axis motor 13, the two motor shafts of the dual-axis motor 13 drive a pair of driving shafts 14 to rotate synchronously, the driving shaft 14 drives the driving gear 15 to rotate synchronously, the driving gear 15 meshes and drives the driven gear 17, the driven shaft 16 and the first hinge plate 18 to swing slowly;

[0045] In step 4, the first hinge plate 18 and the second hinge plate 19 form a limiting effect. When the first hinge plate 18 swings slowly, the second hinge plate 19 drives the front side of the support plate 2 to slowly hinge and rotate along a pair of second ear seats 11, thereby adjusting the inclination angle of the support plate 2 and the tire.

[0046] The utility model solves the problem that the tire cannot be placed tilted and fixed, and the overall structure is compactly designed, which not only facilitates the adjustment of the tilt angle of the tire when it is placed tilted, but also enhances the firmness of the clamping when the tire is placed tilted.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
