[0053] Please refer to Figures 1 to 9, the utility model provides a durable trash can wheel set for installation on the wheel set mounting seat 100 at the bottom of the trash can. The wheel set mounting seat 100 is provided with a shaft hole 110, and the durable trash can wheel set includes a wheel shaft 1, rolling wheels 2, a limiting mechanism 3 and a locking mechanism 4.

[0054] The wheel shaft 1 is arranged through the shaft hole 110.

[0055] The rolling wheels 2 are rotatably arranged at both ends of the wheel shaft 1.

[0056] The limiting mechanism 3 is arranged on the wheel shaft 1 and abuts against the wheel set mounting seat 100 for limiting the axial movement of the wheel shaft 1.

[0057] The locking mechanism 4 connects the wheel shaft 1 and the rolling wheels 2 for limiting the axial movement of the rolling wheels 2.

[0058] Please refer to Figure 2 , when installing the trash can wheel set, first pass the wheel shaft 1 through the shaft hole 110 on the wheel set mounting seat 100, then install the limiting mechanism 3 on the wheel shaft 1 to avoid the axial movement of the wheel shaft 1, and then install the rolling wheels 2 at both ends of the wheel shaft 1. Among them, the wheel shaft 1 can be fixedly installed on the wheel set mounting seat 100 or rotatably installed. When the wheel shaft 1 is fixedly installed on the wheel set mounting seat 100, the rolling wheels 2 are rotatably connected to both ends of the wheel shaft 1 to realize the rolling of the wheel set; when the wheel shaft 1 is rotatably installed, the rolling wheels 2 can be either fixedly connected to the wheel shaft 1 or rotatably connected to the wheel shaft 1 to facilitate the rolling of the wheel set. The locking mechanism 4 can lock the rolling wheels 2 on the wheel shaft 1 to limit the axial movement of the rolling wheels 2 relative to the wheel shaft 1.

[0059] The durable trash can wheel set provided by this embodiment restricts the axial movement of the wheel shaft 1 by arranging the limiting mechanism 3 on the wheel shaft 1, avoiding the offset of the wheel shaft 1 when dragging the trash can; and by connecting the wheel shaft 1 and the rolling wheels 2 with the locking mechanism 4, the mechanical strength of the connection between the rolling wheels 2 and the wheel shaft 1 is enhanced, and the connection structure is not easily damaged when the rolling wheels 2 are axially stressed, solving the problems in the background technology.

[0060] Further, please refer to Figure 3 , in Embodiment 1 provided by this embodiment:

[0061] The shaft diameters at both ends of the wheel shaft 1 are reduced to form mounting ends 11 for mounting the rolling wheels 2.

[0062] The locking mechanism 4 includes gaskets 41 arranged on both sides of the rolling wheels 2 and locking nuts 42 threadedly arranged at the ends of the mounting ends 11.

[0063] Specifically, both ends of the wheel axle 1 are small-diameter ends. When installing the rolling wheel 2 on the mounting end 11, a gasket 41 can be placed on each side of the mounting hole of the rolling wheel 2. The two gaskets 41 respectively abut against the connection between the large-diameter and small-diameter parts of the wheel axle 1 and the locking nut 42. When tightening the locking nut 42, the gasket 41 enhances the stability between the rolling wheel 2 and the wheel axle 1.

[0064] Furthermore, a sliding enhancement mechanism 5 is also included between the wheel axle 1 and the rolling wheel 2. The sliding enhancement mechanism 5 includes a nylon sliding sleeve 51 and / or a bearing 52. The wheel axle 1, the nylon sliding sleeve 51 and / or the bearing 52, and the rolling wheel 2 are sleeved in sequence.

[0065] Among them, the sliding enhancement mechanism 5 can increase the sliding smoothness by reducing the friction between the wheel axle 1 and the rolling wheel 2. The sliding enhancement mechanism 5 can include a single nylon sliding sleeve 51 or a single bearing 52, or both a nylon sliding sleeve 51 and a bearing 52.

[0066] Please refer to Figure 4 , in Embodiment 2 provided in this embodiment, the sliding enhancement mechanism 5 includes a nylon sliding sleeve 51. The nylon sliding sleeve 51 is sleeved on the mounting end 11, and the rolling wheel 2 is mounted on the nylon sliding sleeve 51. When installing the nylon sliding sleeve 51, gaskets 41 can be additionally provided on both sides of the nylon sliding sleeve 5 to enhance the connection stability. It should be noted that in order for the rolling wheel 2 to roll smoothly on the nylon sliding sleeve 51, the length of the nylon sliding sleeve 51 can be greater than the axial length of the rolling wheel 2. Similarly, the nylon sliding sleeve 51 can also be replaced by a bearing 52, and the installation method is the same as above.

[0067] Please refer to Figure 5 and Figure 6 , in Embodiment 3 provided in this embodiment, the sliding enhancement mechanism 5 includes a nylon sliding sleeve 51 and a bearing 52. When installing, the mounting end 11, the nylon sliding sleeve 51, the bearing 52, and the rolling wheel 2 are sleeved in sequence. Specifically, the nylon sliding sleeve 51 and the bearing 52 can be sleeved first and then placed in the mounting hole of the rolling wheel 2, and then restricted from sliding out through structures such as end caps. It should be noted that in order for the rolling wheel 2 to rotate smoothly, the length of the nylon sliding sleeve 51 can be greater than the axial length of the rolling wheel 2, that is, both ends of the nylon sliding sleeve 51 can extend from both sides of the rolling wheel 2 to abut against the gasket 41.

[0068] Furthermore, please refer to Figure 3 , the limiting mechanism 3 includes a limiting groove 31 and a limiting retaining ring 32.

[0069] The number of the limiting grooves 31 is two, which are arranged circumferentially around the wheel axle 1.

[0070] The limiting retaining ring 32 is sleeved in the limiting groove 31 and abuts against the wheel set mounting seat 100.

[0071] Among them, the limiting retaining ring 32 can be a conventional shaft elastic retaining ring. By using tools such as needle-nose pliers, the limiting retaining ring 32 can be conveniently installed in or removed from the limiting groove 31. During installation, the axle 1 can first be passed through the axle hole 110 of the wheel set mounting seat 100, aligning the limiting groove 31 with the position of the baffle on the wheel set mounting seat 100, and then the limiting retaining ring 32 is installed in the limiting groove 31, abutting against the baffle on the wheel set mounting seat 100 to limit the axial movement of the axle 1.

[0072] Further, please refer to Figure 7 and Figure 8 , in Embodiment 4 provided in this embodiment, the locking mechanism 4 includes a first limiting portion 43, a second limiting portion 44, a card slot 45, and a clamping block 46.

[0073] The first limiting portion 43 is arranged on one side of the rolling wheel 2 adjacent to the end of the axle 1.

[0074] The second limiting portion 44 is arranged on one side of the rolling wheel 2 away from the end of the axle 1.

[0075] The card slot 45 is arranged in a circumferential direction around the axle 1.

[0076] The number of the clamping blocks 46 is multiple. The multiple clamping blocks 46 are arranged in a circumferential direction along the inner circumferential side of the rolling wheel 2 and are located between the first limiting portion 43 and the second limiting portion 44. The clamping blocks 46 are in clamping fit with the card slot 45.

[0077] Among them, the clamping blocks 46 can be fixedly arranged in the mounting holes of the rolling wheel 2. When the axle 1 passes through the mounting holes of the rolling wheel 2, the clamping blocks 46 can clamp the card slot 45, thereby avoiding the axial movement of the rolling wheel 2. Since the clamping blocks 46 are arranged in multiple along the inner circumferential side of the mounting holes, when in clamping fit with the card slot 45, they can have sufficient connection strength and are not easily damaged when axially stressed. The first limiting portion 43 and the second limiting portion 44 can be in transitional fit with the axle 1 to support the rolling wheel 2 during rotation.

[0078] Further, the slip increasing mechanism 5 is arranged between the first limiting portion 43 and the clamping block 46, and / or the slip increasing mechanism 5 is arranged between the second limiting portion 44 and the clamping block 46.

[0079] Specifically, the number of the slip increasing mechanisms 5 can be one or two. When there is only one slip increasing mechanism 5, the slip increasing mechanism 5 can be arranged between the first limiting portion 43 and the clamping block 46 or between the second limiting portion 44 and the clamping block 46; when there are two slip increasing mechanisms 5, the two slip increasing mechanisms 5 can be respectively arranged on both sides of the clamping block 46.

[0080] Please refer to Figure 8, in the embodiment provided by this embodiment, the number of the anti-slip mechanisms 5 is one, and it is located between the second limiting portion 44 and the clamping block 46, and the anti-slip mechanism 5 is a bearing 52 to effectively reduce the friction force.

[0081] Further, please refer to Figure 7 and Figure 9 , the locking mechanism 4 further includes an elastic steel ring 47. A plurality of elastic steel sheets 471 are arranged at intervals around the side of the elastic steel ring 47 away from the first limiting portion 43. The elastic steel sheets 471 are bent towards the first limiting portion 43 and inclined along the direction close to the clamping groove 45, and the elastic steel sheets 471 form the clamping block 46.

[0082] Among them, the design of the elastic steel ring 47 is convenient for production and installation. Specifically, during installation, the elastic steel ring 47 and the bearing 52 can be sequentially placed in the installation hole of the rolling wheel 2, and their axial movement is restricted by the first limiting portion 43 and the second limiting portion 44 to prevent the elastic steel ring 47 and the bearing 52 from slipping out. The extending direction of the elastic steel sheets 471 faces the end side of the wheel shaft 1. When the wheel shaft 1 is inserted into the installation hole of the rolling wheel 2, the end of the wheel shaft 1 can pass through the elastic steel ring 47, and the elastic steel sheets 471 can be stuck to the limiting groove 31.

[0083] Further, in the embodiment provided by this embodiment, the inner peripheral diameter of the first limiting portion 43 is smaller than the inner peripheral diameter of the second limiting portion 44. Specifically, the inner diameters of the bearing 52, the elastic steel ring 47 and the first limiting portion 43 decrease in sequence. The inner diameter of the second limiting portion 44 can be equal to the inner diameter of the bearing 52, and the end diameter of the wheel shaft 1 can be smaller than its middle diameter, which is convenient for installing the elastic steel ring 47 and the bearing 52 to make the bearing 52 block the elastic steel ring 47 to prevent the elastic steel ring 47 from slipping out, and is also convenient for the wheel shaft 1 to be smoothly inserted into the installation hole of the rolling wheel 2.

[0084] Further, the second limiting portion 44 is a cover plate, and the cover plate is threadedly connected to the rolling wheel 2.

[0085] Further, the limiting mechanism 3 includes a limiting sliding sleeve 33 movably sleeved on the wheel shaft 1. One end of the limiting sliding sleeve 33 is close to the second limiting portion 44, and the other end is close to the wheel set mounting seat 100 to limit the axial movement of the wheel shaft 1.

[0086] Further, the limiting sliding sleeve 33 is integrally connected to the second limiting portion 44 for easy installation.

[0087] Working principle:

[0088] Please refer to Figure 1 and Figure 2, when installing the trash can wheel set, first pass the wheel axle 1 through the axle hole 110 on the wheel set mounting seat 100, then install the limiting mechanism 3 on the wheel axle 1 to prevent axial movement of the wheel axle 1, and then install the rolling wheels 2 at both ends of the wheel axle 1. Among them, the wheel axle 1 can be fixedly installed on the wheel set mounting seat 100 or rotatably installed. When the wheel axle 1 is fixedly installed on the wheel set mounting seat 100, the rolling wheels 2 are rotatably connected to both ends of the wheel axle 1 to realize the rolling of the wheel set; when the wheel axle 1 is rotatably installed, the rolling wheels 2 can either be fixedly connected to the wheel axle 1 or rotatably connected to the wheel axle 1 to facilitate the rolling of the wheel set.
