Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] Example:

[0029] The embodiment of the utility model provides a foam wheel with high strength and strong supporting force, which is intended to solve the technical problems in the prior art that the foam wheel body is easy to fall off during use and is inconvenient to replace;

[0030] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0031] A foam wheel with high strength and strong supporting force, comprising a wheel hub 1, an outer sleeve wheel 2 is sleeved on the outer side of the wheel hub 1;

The center ring 101 is sleeved on the inner side of the outer sleeve wheel 2, the fixing ring 102 is fixedly connected to the rear end of the outer side of the center ring 101, and the blocking ring 103 is sleeved on the front end of the outer side of the center ring 101. The center ring 101 mainly supports the outer sleeve wheel 2, and the fixing ring 102 and the blocking ring 103 fix and block the outer sleeve wheel 2 to prevent the outer sleeve wheel 2 from falling off. Several support plates 104 are fixedly connected to the inner side of the center ring 101 and are evenly spaced. Several support plates 104 support the center ring 101, and the bearing 105 is fixedly connected to the connection between the several support plates 104. The bearing 105 is used for an external connecting shaft for easy installation.

[0034] Among them, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The connection between the center ring 101 and the support plate 104 is chamfered. The circular chamfer can increase the support strength between the center ring 101 and the support plate 104, and the circular chamfer is not easy to crack, which can increase the service life. A number of limit grooves 3 are evenly spaced at the front end of the center ring 101. The middle section of the center ring 101 is recessed inward into an arc shape.

The plurality of reinforcing ribs 5 can increase the strength of the fixing ring 102 and the blocking ring 103, and effectively increase the service life of the fixing ring 102 and the blocking ring 103. The outer rings of the fixing ring 102 and the blocking ring 103 expand toward the front and rear ends respectively, and the cross-section is fan-shaped and open, so that when the outer sleeve wheel 2 is in use, the fixing ring 102 and the blocking ring 103 can better disperse the pressure.

[0037] For further information, see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The inner side of the blocking ring 103 is fixedly connected to the positions corresponding to the plurality of limit grooves 3 with limit feet 6, the limit feet 6 are adapted for use with the limit grooves 3, a through hole 7 is provided at the position corresponding to the limit feet 6 and the limit grooves 3, the through hole 7 runs through the front and rear ends of the center ring 101, a bolt 8 is sleeved on the inner side of the through hole 7, and a nut 9 is threadedly connected to the front end of the bolt 8. During the installation process, the limit feet 6 are aligned with the limit grooves 3, the bolt 8 is inserted from the rear end of the through hole 7, and the nut 9 is tightened, so that the blocking ring 103 can be sleeved on the right end of the center ring 101.

[0038] For further information, see Figure 1 and Figure 2 A plurality of anti-skid grooves 10 are evenly spaced on the outside of the outer sleeve wheel 2, which can increase the grip of the outer sleeve wheel 2 and prevent the outer sleeve wheel 2 from slipping. A clamping groove 11 is provided on the front and rear sides of the outer sleeve wheel 2, which is adapted for use with the circular clamping ring 4. The clamping groove 11 is clamped with the circular clamping ring 4 to prevent the outer sleeve wheel 2 from falling off.
