[0027] During actual use, the rim to be tested is sleeved on the rotating rod 11, and the hydraulic rod 4 is turned on, which drives the lifting plate 7 to move up and down, and the lifting plate 7 drives the slider 10 and the rotating rod 11 to move up and down, so that the rim contacts the bottom plate 1, and the pressure sensor 5 detects the pressure of the hydraulic rod 4, and the pressure is displayed on the display screen 6. Then the motor 9 is turned on, and the motor 9 drives the screw rod 901 to rotate, and the screw rod 901 drives the slider 10 to move left and right along the screw rod 901. The slider 10 drives the rim to move downward through the rotating rod 11 and rolls on the bottom plate 1, so as to achieve the effect of rim pressure resistance detection, and the durability of the rim pressure resistance is detected by the timer on the display screen 6.

[0028] In this embodiment, the pressure sensor 5 is electrically connected to the display screen 6, and a timer is provided on the display screen 6, so that the display screen 6 can display the pressure sensed by the pressure sensor 5 and detect the durability of the rim's resistance to pressure through the timer.

[0029] In this embodiment, the guide sleeve 701 is sleeved on the guide column 2, and the guide sleeve 701 can be lifted up and down along the guide column 2 to ensure the stability of the lifting plate 7.

[0030] In this embodiment, the left diameter of the rotating rod 11 is larger than the right diameter, and the rotating rod 11 gradually decreases in a step-like manner, so that the rotating rod 11 is suitable for the installation and detection of rims with different central apertures.

[0031] In this embodiment, an anti-slip assembly is fixedly provided on the left side surface of the slider 10, and the anti-slip assembly includes a mounting plate 12, an electric telescopic rod 13, a rectangular sleeve 14, a blocking rod 15 and a handle 1501.

The friction between the through rod 1401 and the blocking rod 15 can achieve the effect of limiting the blocking rod 15.

[0035] By providing an anti-slip assembly, when the rim is installed on the rotating rod 11, the electric telescopic rod 13 is extended, and the fixing plate 1402 is pulled upward so that the through rod 1401 does not contact the blocking rod 15, and then the blocking rod 15 is pulled to the left so that the blocking rod 15 does not affect the installation of the rim. After the rim is installed, the blocking rod 15 is pushed to the right so that the blocking rod 15 is on the outside of the rim, and the fixing plate 1402 is released. The elastic force of the sleeve spring 1403 makes the through rod 1401 contact the blocking rod 15 to position the blocking rod 15, and then the electric telescopic rod 13 is contracted so that the blocking rod 15 contacts the rim, thereby preventing the rim from falling off the rotating rod 11.
