[0003] Although the nylon wheel in the prior art has achieved the effect of cost saving, it still has some shortcomings: when the existing nylon wheel is used as a load-bearing roller, its own elastic effect is poor, resulting in greater vibration on uneven roads, which in turn causes damage to the internal bearings; secondly, although the nylon wheel has a wear-resistant effect, it will also cause severe wear on the outside under long-term use, and when used as a roller, it will reduce the overall height of the upper device of the roller, and when the entire device is replaced, it will lead to an increase in cost. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figures 1 to 4 As shown, the utility model provides a reinforced nylon wheel, comprising: an outer ring layer 1, a middle ring layer 2, an elastic member 3 and an inner ring layer 4, the rear side of the outer ring layer 1 is provided with a back plate 12 of an integral structure, and the inner ring of the outer ring layer 1 is provided with a connecting block 14 of an integral structure, and a reinforcing block 11 is connected between the outer ring layer 1 and the middle ring layer 2, a threaded hole 111 is opened on the front side of the reinforcing block 11, and a yield step 13 is provided on the front side of the reinforcing block 11, the elastic member 3 is connected between the middle ring layer 2 and the inner ring layer 4, and a bearing 5 is installed on the inner side of the inner ring layer 4.

[0023] In this embodiment, the outer ring layer 1, the middle ring layer 2, the elastic member 3 and the inner ring layer 4 constitute the main structure of the reinforced nylon wheel involved in this application.

[0024] Among them, the outer ring layer 1, the middle ring layer 2, the inner ring layer 4, the reinforcing block 11 and the back plate 12 are all made of carbon fiber nylon material, that is, carbon fiber is compounded in the nylon material to increase its wear resistance.

[0025] Specifically, a metal threaded sleeve is embedded in the threaded hole 111 to enhance the stability of the bolt connection.

[0026] As a preferred embodiment, by providing a clearance step 13, when the connecting block 14 contacts the reinforcing block 11, the front side of the outer ring layer 1 is flush with the overall end surface of the nylon wheel.

[0027] like Figure 2 and Figure 3As shown, a groove is provided on the front side of the back plate 12, and the reinforcement blocks 11 are arranged in a ring shape and equidistantly in the groove, and the reinforcement blocks 11 are set to an isosceles trapezoidal structure, and the connecting blocks 14 are arranged in a ring shape and equidistantly on the inner ring side of the outer ring layer 1, and a connecting hole is opened in the connecting block 14, and the connecting hole is aligned with the threaded hole 111, the front and rear end surfaces of the outer ring layer 1 are flush with the middle ring layer 2 and the inner ring layer 4, and the middle ring layer 2 is connected to the inner side of the back plate 12, and the outer ring layer 1 is sleeved on the outer ring of the reinforcement block 11 and the back plate 12.

[0028] As a preferred implementation, the grooves are provided to save materials for making the nylon wheel and reduce the weight of the nylon wheel, thereby reducing costs and reducing the effect of the wheel's own weight on wear.

[0029] As a preferred implementation, the reinforcing block 11 is provided to play the role of reinforcing ribs, thereby reducing the manufacturing material while having good internal support strength.

[0030] like Figure 1 and Figure 4 As shown, the elastic members 3 are arranged in an annular matrix structure, and the elastic members 3 are provided with a double layer in the axial direction of the middle ring layer 2. The elastic members 3 include end tubes 31 on the inner and outer sides, and the end tubes 31 are respectively fixedly connected to the middle ring layer 2 and the inner ring layer 4, and a piston rod 35 is slidably connected between the end tubes 31, and a spring 36 is sleeved on the outer side of the piston rod 35. Piston blocks 34 are connected to both ends of the piston rod 35, and the piston block 34 is slidably connected to the inside of the end tube 31, and hydraulic oil 32 is provided inside the end tube 31, and a connecting cavity 33 is opened on the inner wall of the end tube 31, and the piston block 34 is located between the two ports of the connecting cavity 33.

[0031] As a preferred embodiment, by providing multiple groups of elastic members 3, a radial damping and shock absorbing effect is achieved during the rolling of the nylon wheel, thereby reducing damage to the internal bearing 5 and providing shock absorbing protection to the transfer device installed on the nylon wheel.

[0032] When in use, the end tube, piston rod, piston block and spring included in the elastic part are utilized so that when the nylon wheel vibrates, the piston block slides inside the end tube, thereby squeezing the hydraulic oil, so that the hydraulic pressure flows from one side of the piston block through the connecting cavity to the other side. Since the inner diameter of the flow cavity is small, it has a deceleration effect on the hydraulic oil, and then has a buffering and damping effect on the piston block, so that the nylon wheel has a shock-absorbing and buffering effect, thereby reducing the damage to the internal bearing. During replacement, when the outer ring layer is severely worn, the bolts inside the connecting hole are removed, and then the outer ring layer is taken out from the side of the give way step, and then the new outer ring layer is re-installed on the outside of the reinforcement block, while keeping the connecting block corresponding to the reinforcement block until the connecting block is blocked by the reinforcement block limit. At this time, the outer ring layer is rotated so that the hole positions of the connecting hole and the threaded hole are opposite, and then they are connected and fixed by bolts to complete the replacement.

[0033] The reinforced nylon wheel of the utility model can effectively solve the problems that the existing nylon wheel has no shock-absorbing effect when used as a roller, is not convenient for partial replacement, and has high cost of use. It realizes the addition of the shock-absorbing function of the nylon wheel on the basis of the existing reinforced nylon wheel technology, and is convenient for partial replacement of the nylon wheel.
