DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Reference Figure 1-Figure 7 As shown, a scratch-resistant and wear-resistant heavy-load tire comprises a wheel hub 1, a tire 2 and a protective plate 3. The tire 2 is fixedly sleeved on the outer ring of the wheel hub 1, and the surface of the protective plate 3 is provided with an adhesive rubber ring 4 for gluing to the surface of the wheel hub 1. The protective plate 3 is glued to the surface of the wheel hub 1 by the adhesive rubber ring 4, which can prevent external objects from directly contacting the wheel hub 1 during driving of the tire, thereby preventing the wheel hub 1 from being scratched. At the same time, there is no need to replace the wheel hub 1, and only the protective plate 3 that is severely worn needs to be replaced.

[0021] A sealing assembly is provided on the surface of the protective plate 3, which is used to prevent rainwater from contacting the adhesive rubber ring 4. The sealing assembly includes an annular airbag 5 fixedly installed on the surface of the protective plate 3. The diameter of the annular airbag 5 is larger than the diameter of the adhesive rubber ring 4. A plurality of telescopic springs 6 are fixedly installed in a circular shape inside the annular airbag 5. Both ends of the telescopic spring 6 are fixedly connected to the inner wall of the annular airbag 5. When the protective plate 3 is bonded to the surface of the wheel hub 1 through the adhesive rubber ring 4, the annular airbag 5 will also be against the wheel hub 1. Since the diameter of the annular airbag 5 is larger than the diameter of the adhesive rubber ring 4, the adhesive rubber ring 4 can be covered to prevent external water from contacting the adhesive rubber ring 4, thereby reducing the viscosity of the adhesive rubber ring 4 and improving the stability of the adhesion.

[0022] A T-shaped mounting groove is provided on the surface of the protective plate 3, and an adsorption component is provided in the mounting groove. The adsorption component is used to adsorb the wheel hub 1. The adsorption component includes a hollow rod 7 with a closed end and a suction cup 8 fixedly installed on the open end of the hollow rod 7. A mounting ring 9 is fixedly sleeved on the hollow rod 7, and a connecting rod is symmetrically fixedly installed on the outer ring wall of the mounting ring 9. One end of the connecting rod is fixedly connected to the wall of the mounting groove. An air inlet 10 is provided on the surface of the hollow rod 7. An arc plate 11 for blocking the air inlet 10 is slidably arranged in the hollow rod 7. A rotating port is provided at one end of the hollow rod 7 that is closed, and a rotating shaft 12 is sealed and rotatably installed in the rotating port. The rotating shaft 12 is located at One end in the hollow rod 7 is connected to the arc plate 11 through a connecting rod, a circular plate 13 is fixedly installed at one end of the rotating shaft 12 located outside, a torsion spring 14 is sleeved on the rotating shaft 12, and the two ends of the torsion spring 14 are respectively fixedly connected to the circular plate 13 and the hollow rod 7, a mounting opening is opened at the center of the surface of the protective plate 3, a first spring rod 15 is fixedly installed in the mounting opening, a friction strip 16 is vertically arranged in the mounting groove, the side wall of the circular plate 13 is provided with anti-slip grooves, the friction strip 16 corresponds to the position of the circular plate 13, the mounting opening wall is provided with a through opening connected to the mounting groove, a U-shaped fixing rod 17 is fixedly installed on the top of the first spring rod 15, and one end of the fixing rod 17 The protective plate 3 passes through the through opening and is fixedly connected with one end of the friction strip 16; when the protective plate 3 is bonded to the wheel hub 1 through the adhesive rubber ring 4, the suction cup 8 will also be pressed against the wheel hub 1, and under the influence of the pressing force, the suction cup 8 will be deformed, and the gas in the suction cup 8 will slip out from the gap between the suction cup 8 and the wheel hub 1, so that the suction cup 8 will be attracted to the wheel hub 1. When the viscosity of the adhesive rubber ring 4 fails, the protective plate 3 will still be attracted to the wheel hub 1 due to the adsorption force of the suction cup 8 and will not be separated, thereby improving the stability of the fixed protective plate 3; and when it is necessary to release the adsorption of the suction cup 8, just control the first spring rod 15 to shrink , so that the friction strip 16 moves. During the movement, the friction strip 16 will resist the circular plate 13. Under the action of friction, the circular plate 13 will rotate with the rotating shaft 12 and the arc plate 11 until the arc plate 11 rotates to no longer cover the air inlet 10. At this time, the gas in the outside will enter the hollow rod 7 from the air inlet 10, thereby releasing the adsorption of the suction cup 8. When the first spring rod 15 is released, the friction strip 16 will quickly move and reset, and the circular plate 13, the rotating shaft 12 and the arc plate 11 will also quickly rotate and reset under the elastic potential energy of the torsion spring 14, and the arc plate 11 will rotate again to cover the air inlet 10.

[0023] The surface of the protective plate 3 is symmetrically provided with mounting grooves, in which second spring rods 18 are fixedly installed, and baffles 19 are fixedly installed at one end of the two second spring rods 18. Two limiting plates 20 are fixedly installed on the surface of the baffle 19, and a limited displacement space 21 for limiting the movement of the fixing rod 17 is formed between the two limiting plates 20; in the initial state, the baffle 19 will cover the mounting opening under the elastic potential energy of the two second spring rods 18, thereby improving the overall aesthetics of the protective plate 3, and at this time the fixing rod 17 will be located in the limited displacement space 21 between the two limiting plates 20, thereby preventing the first spring rod 15 from being extended and retracted due to the influence of centrifugal force during the rotation of the wheel hub 1, and when it is necessary to control the contraction of the first spring rod 15, it is only necessary to pull the baffle 19 so that the baffle 19 no longer covers the mounting opening, so that the two second spring rods 18 are stretched until the fixing rod 17 moves out of the limited displacement space 21.
