It should be understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein can be arranged and designed in a variety of different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0029] The following combination Figure 1-8 The specific embodiment of the present invention is described as follows: a wheel limit structure for a trash can, comprising:

[0030] The shaft body 1 is installed and connected with the mounting hole of the trash can 4, and includes a positioning rod 11 and a limiting rod 12. The positioning rod 11 is threadedly connected to the limiting rod 12, and the diameter of the limiting rod 12 is larger than the diameter of the positioning rod 11. The positioning rod 11 is inserted into the two mounting holes on both sides of the trash can 4 by using the threaded fit of the positioning rod 11 and the limiting rod 12, so that the two ends of the positioning rod 11 are in contact with the two side surfaces of the trash can 4. When the positioning rod 11 and the limiting rod 12 are threadedly fitted, since the outer diameter of the limiting rod 12 is larger than the outer diameter of the positioning rod 11, the positioning rod 11 and the limiting rod 12 are threadedly connected to realize the limitation of the shaft body 1 on the trash can 4, thereby preventing the shaft body 1 from moving on the trash can 4;

[0031] The rotating wheel 2 is rotatably connected to the limiting rod 12 to serve as a moving part of the trash can 4;

[0032] The limiting member 3 is used for limiting the installation of the wheel 2 on the shaft body 1 to achieve the installation limitation of the wheel 2 on the shaft body 1 and prevent the wheel 2 from moving back and forth along the length direction of the shaft body 1. The limiting member 3 includes a limiting bolt 35, and the limiting bolt 35 is threadedly connected to the limiting rod 12. The limiting bolt 35 limits the wheel 2 at one end of the shaft body 1 to prevent the wheel 2 from moving outward on the shaft body 1.

[0033] Please refer to Figure 1 As shown, the diameter of the positioning rod 11 is equal to the distance formed between the two mounting holes of the trash can 4, so that when the shaft body 1 and the trash can 4 are installed and connected, the limiting rod 12 is threadedly connected at both ends of the trash can 4, so that the positioning rod 11 and the limiting rod 12 are threadedly connected. At the same time, the trash can 4 is clamped under the action of the threaded connection to prevent the limiting rod 12 from moving on the trash can 4. The limiting rod 12 is provided with an external thread 123, and an internal thread 111 is formed at both ends of the positioning rod 11. The internal thread 111 is adapted to the external thread 123. The positioning rod 11 and the limiting rod 12 are threadedly connected through the threaded matching of the internal thread 111 and the external thread 123. By threading the positioning rod 11 and the limiting rod 12, the installation complexity of the shaft body 1 and the trash can 4 is effectively reduced.

[0034] Please refer to Figure 1 As shown, the diameter of the limiting rod 12 is larger than the diameter of the installation hole of the trash can 4, so as to prevent the limiting rod 12 from passing through the installation hole of the trash can 4 when being installed and connected with the trash can 4.

[0035] Please refer to Figure 2-6 As shown, the limit member 3 also includes a limit ring 31, which is sleeved on the limit rod 12, and a positioning hole 121 is provided on the limit rod 12. One end of the limit ring 31 is provided with a first positioning block 312, and the first positioning block 312 is fixedly connected to the limit ring 31, and the first positioning block 312 is adapted to the positioning hole 121. One end of the limit ring 31 is in contact with the limit rod 12, and the other end is in contact with one end of the rotating wheel 2. When the limit ring 31 is connected to the limit rod 12, the first positioning block 312 fixed thereon is plugged into the positioning hole 121 provided on the limit rod 12, so that the limit ring 31 and the limit rod 12 can only abut against each other after sliding horizontally, and cannot rotate with each other.

[0036] Please refer to Figure 4-8As shown, a second positioning block 311 is provided at one end of the limiting ring 31 away from the first positioning block 312, and the second positioning block 311 is fixedly connected to the limiting ring 31. A nylon roller 32 is provided on the limiting rod 12, and the nylon roller 32 is sleeved on the limiting rod 12. The nylon roller 32 is sleeved on the limiting rod 12.

[0037] Please refer to Figure 4-8 As shown, a bearing 33 is sleeved on the nylon roller 32, and grooves 331 are formed at both ends of the bearing 33. A roller 332 is rotatably provided in the groove 331. The second positioning block 311 is plugged into the groove 331, and the roller 332 is rotatably connected in the groove 331. At the same time, the inner ring of the rotating wheel 2 is rotatably connected to the roller 332 to reduce the friction force of the rotating wheel 2 rotating on the shaft body 1. The second positioning block 311 is plugged into the groove 331 to lock the bearing 33 on the limit rod 12 to avoid rotation with the limit rod 12, thereby limiting the bearing 33.

[0038] Please refer to Figure 8 As shown, there are multiple rollers 332, and the multiple rollers 332 are distributed in a circular array along the bearing 33. The wheel 2 is sleeved on the bearing 33 and is rotatably connected to the bearing 33 to reduce the friction formed between the wheel 2 and the shaft 1 when rotating.

[0039] Please refer to Figure 2 As shown, a gasket 34 is provided on one side of the runner 2, and the gasket 34 is located between the runner 2 and the limiting bolt 35. The gasket 34 and the limiting bolt 35 are used to limit the outer side of the runner 2. The inner side of the runner 2 is limited by the limiting ring 31, and the outer side is limited by the gasket 34 and the limiting bolt 35, so that the runner 2 is limited between the limiting bolt 35 and the limiting ring 31, and is rotatably connected to the limiting rod 12.

[0040] The working principle of this utility model:

[0041] Insert the positioning rod 11 into the mounting holes on both sides of the trash can 4, and make the two ends of the positioning rod 11 fit with the end faces of the mounting holes of the trash can 4 respectively;

[0042] The limiting rods 12 are connected to both ends of the positioning rod 11 respectively, and one end of the limiting rod 12 provided with the external thread 123 is threadedly connected to the internal thread 111 of the positioning rod 11. Since the outer diameter of the limiting rod 12 is larger than the outer diameter of the positioning rod 11 and the aperture of the installation hole of the trash can 4, when the two limiting rods 12 are synchronously threadedly installed, the limiting rods 12 and the trash can 4 are gradually clamped and limited, and are limited to such an extent that the two limiting rods 12 cannot be threadedly rotated on the positioning rod 11, that is, the positioning rod 11 and the limiting rod 12 are limitedly installed on the trash can 4;

[0043] Insert the other end of the limiting rod 12 away from the external thread 123 through the limiting ring 31, and insert the first positioning block 312 at one end of the limiting ring 31 into the positioning hole 121 to prevent the limiting rod 12 and the limiting ring 31 from rotating relative to each other. Then, sleeve the nylon roller 32 onto the limiting rod 12.

[0044] The bearing 33 is sleeved onto the nylon roller 32 , and at the same time, the groove 331 on the bearing 33 is plugged into and matched with the second positioning block 311 fixedly provided on the limiting ring 31 to limit the bearing 33 ;

[0045] The wheel 2 is sleeved on the bearing 33 so that the multiple rollers 332 rotating in the grooves 331 of the bearing 33 are tangential to the inner ring of the wheel 2. At the same time, the inner ring of the wheel 2 is rotatably connected to the multiple rollers 332.

[0046] A gasket 34 is sleeved on the limit rod 12 so that the gasket 34 fits against the outer side of the wheel 2. At the same time, a limit bolt 35 is threadedly connected to the limit rod 12 and the limit bolt 35 is tightened to limit the position of the wheel 2 so that the wheel 2 can only rotate between the limit ring 31 and the gasket 34 and cannot move along the length direction of the limit rod 12.
