The first rim 1 and the second rim 2 are equipped with vertical rings, and the vertical rings are provided with air nozzles, and the air nozzles are installed at the inner lower ends of the first rim 1 and the second rim 2.

[0027] When the first rim 1 and the second rim 2 are assembled, the positioning rod 10 is aligned and inserted into the positioning hole 11. Only in this way can the threaded mounting holes 7 on the first rim 1 and the second rim 2 be aligned.

[0028] A vertical ring is installed on the rim, and an air nozzle is arranged on the vertical ring. The air nozzle is installed at the inner lower end of the first rim 1 and the second rim 2. The vertical ring can limit the left and right sides of the solid tire and the vacuum tire. After installation, the positioning is more accurate, more stable during use, and the effect is better.

[0029] When installed as a vacuum tire, it can be inflated through an air nozzle. It can be applied to both vacuum tires and solid tires, and has greater applicability.

[0030] See also Figure 1-2 The anti-falling mechanism includes a fixing plate 12 fixed on the first rim 1, an elastic sheet 13 is fixed on the fixing plate 12, a spring 14 is fixed on the elastic sheet 13, a resistance plate 15 is fixed on the other end of the spring 14, a telescopic rod 16 is fixed between the resistance plate 15 and the elastic sheet 13, the spring 14 is sleeved on the telescopic rod 16, and a storage cylinder 17 is fixed on the resistance plate 15.

After the installation is completed, loosen the elastic sheet 13, and the elastic sheet 13 and the spring 14 are reset. Finally, the storage cylinder 17 will be sleeved on the end of the threaded rod 8, and the end of the threaded rod 8 and the contact plate 15 will use the spring to tighten the nut 9, effectively preventing the nut from vibrating and falling off.

[0035] After installation, the secondary elastic sheet 26 is loosened, so that the secondary elastic sheet 26 is reset, and the secondary spring 27 drives the secondary contact plate 28 to press against the head of the secondary threaded rod 24, thereby effectively preventing the secondary threaded rod 24 from being loosened.

[0036] A storage cylinder as described above may also be designed on the secondary contact plate 28 , and the storage cylinder of the secondary contact plate 28 wraps the head of the secondary threaded rod 24 to further prevent the secondary threaded rod 24 from loosening.

[0037] Similarly, the head of the threaded rod 8 can also be prevented from loosening by this method, which is a structure disclosed in the present application and will not be described in detail here.

[0038] During specific operation, the first rim 1 and the second rim 2 are assembled, the first sealing ring 4 is bonded into the sealing step 3, and the second sealing ring 6 is bonded into the sealing groove 5. When the two are butt-jointed, double sealing is achieved. When used with a vacuum tire, the sealing performance can be improved, air leakage can be prevented, and the tire pressure can be stabilized.

[0039] When in use, a solid tire or a vacuum tire is installed on the first rim 1, and when the second rim 2 is assembled, the first rim 1 and the second rim 2 are butt-jointed, so that the threaded mounting holes 7 thereon correspond to each other, and the threaded rod 8, that is, the bolt, passes through the threaded mounting holes 7 on the first rim 1 and the second rim 2.

[0040] The threaded rod 8 first passes through the threaded mounting hole 7 on the second rim 2, and then passes through the threaded mounting hole 7 on the first rim 1. The threaded end is then threaded onto the nut 9, so that the first rim 1 and the second rim 2 can be fixedly installed.
