[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. 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.

[0030] 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.

[0031] The following combination Figure 1-6 The present invention is a specific embodiment of a trash can wheel set that is easy to install, comprising:

[0032] The positioning rod 1 has mounting threads 10 formed at both ends. The positioning rod 1 serves as an axis for mounting with the trash can 14 and is installed and connected in the mounting holes at both ends of the trash can 14.

[0033] The limiting rod 2 is sleeved on the positioning rod 1. The limiting rod 2 is formed with a mounting step 9. The mounting step 9 is rotatably provided with a rotating wheel 7. The limiting rod 2 is respectively connected to the rotating wheel 7 and the positioning rod 1; the mounting step 9;

[0034] The limiting member 3 is located between the positioning rod 1 and the limiting rod 2. The diameter of the limiting member 3 is larger than the diameter of the mounting hole of the trash can 14. The limiting member 3 is sleeved on the intersection of the positioning rod 1 and the limiting rod 2 by means of the sleeve connection between the positioning rod 1 and the limiting rod 2. The limiting member 3 is clamped between the positioning rod 1 and the limiting rod 2 by means of the connection between the positioning rod 1 and the limiting rod 2. Since the diameter of the limiting member 3 is larger than the diameter of the mounting hole of the trash can 14, the limiting member 3 limits the positioning rod 1, preventing it from moving laterally within the mounting hole of the trash can 14.

[0035] The locking bolt 8 is located at the end of the rotating wheel 7 away from the limiting member 3 and is threadedly engaged with the mounting thread 10. The locking bolt 8 is used to lock the limiting rod 2 and the limiting member 3 on the positioning rod 1. The locking member thread is threadedly engaged with the mounting thread 10 formed on the positioning rod 1, and the threaded engagement between the two is utilized to achieve mutual locking between the positioning rod 1 and the limiting rod 2, so that the limiting rod 2 cannot move along the length direction of the positioning rod 1, further achieving the locking of the limiting rod 2 and the limiting member 3 on the positioning rod 1.

[0036] Please refer to Figure 6 As shown, the positioning rod 1 includes:

[0037] The length of the first rod section 15 is equal to the distance between the outer end surfaces of the mounting holes at both ends of the trash can 14. When the first rod section 15 is plugged into the mounting holes of the trash can 14, it is plugged into the mounting holes at both ends of the trash can 14 to achieve the installation connection between the positioning rod 1 and the trash can 14, and realize mutual locking. At the same time, the two ends of the first rod section 15 are flush with the outer end surfaces of the mounting holes.

[0038] The second rod segment 16 has a diameter smaller than that of the first rod segment 15, providing a socket space for the installation of the limiting rod 2. The mounting thread 10 is located at the end of the first rod segment 15 away from the first rod segment 15. The limiting rod 2 is socketed on the second rod segment 16 to achieve the socket installation between the positioning rod 1 and the limiting rod 2;

[0039] The limiting member 3 is located at the joint of the first rod segment 15 and the second rod segment 16. By installing the limiting rod 2 on the second rod segment 16, the limiting member 3 is clamped on the second rod segment 16 so that it is located at the joint between the first rod segment 15 and the second rod segment 16.

[0040] Please refer to Figure 6As shown, the diameter of the mounting step 9 is smaller than the diameter of the limiting rod 2 , and a positioning strip 11 is provided on the mounting step 9 . The positioning strip 11 is fixedly connected to the circumference of the mounting step 9 . The mounting step 9 is used to mount the runner 7 .

[0041] Please refer to Figure 2-6 As shown, a bearing 6 is provided on the mounting step 9, the inner ring of the bearing 6 is spline-connected to the mounting step 9, the runner 7 is fixedly connected to the outer ring of the bearing 6, and the runner 7 is spline-connected to the runner 7 through a positioning bar 11, so that the bearing 6 is mounted and connected on the mounting step 9. At the same time, the inner ring of the bearing 6 is fixedly connected to the limit rod 2 so that it cannot rotate with the mounting step 9. The runner 7 is mounted on the outer ring of the bearing 6 and is rotatably connected to the limit rod 2 through the bearing 6 to reduce the friction generated when the runner 7 rotates.

[0042] Please refer to Figure 5-6 As shown, a first limit retaining ring 4 is provided at the junction of the installation step 9 and the limit rod 2, and the first limit retaining ring 4 is sleeved on the installation step 9, one end of the first limit retaining ring 4 is in contact with the limit rod 2, and the other end is in contact with the inner ring of the bearing 6; a second limit retaining ring 5 is provided at the end of the rotating wheel 7 away from the first limit retaining ring 4, one end of the second limit retaining ring 5 is in contact with the locking bolt 8, and the other end is in contact with the inner ring of the bearing 6, the first limit retaining ring 4 and the second limit retaining ring 5 are respectively located at both ends of the bearing 6, and are respectively used to limit the installation connection of the bearing 6 on the limit rod 2, so as to avoid the outer ring of the bearing 6 from contacting the limit rod 2 and increasing the friction generated when the rotating wheel 7 rotates, and the second limit retaining ring 5 is used to prevent the locking bolt 8 from directly contacting the outer ring of the bearing 6 to form friction.

[0043] In the first embodiment of the limiting member 3, please refer to Figure 3 As shown, the limiting member 3 is a deformable retaining ring 12, and the deformable retaining ring 12 limiting member 3 is sleeved on the second rod segment 16. The deformable retaining ring 12 limiting member 3 is deformed when squeezed, and the deformable retaining ring 12 limiting rod 2 is sleeved and installed on the positioning rod 1. Under the installation pushing action of the deformable retaining ring 12 limiting rod 2 on the positioning rod 1, the deformable retaining ring 12 limiting member 3 is deformed after being clamped, thereby changing the outer diameter of the deformable retaining ring 12 limiting member 3, so that its outer diameter is larger than the diameter of the installation hole of the trash can 14.

[0044] In the second embodiment of the limiting member 3, please refer to Figure 3-6As shown, the limiting member 3 is a sheet-shaped limiting member 3, the diameter of which is larger than the diameter of the mounting hole of the trash can 14. Compared with the previous embodiment, the sheet-shaped limiting member 3 can directly display the limiting installation of the positioning rod 1 on the trash can 14, avoiding squeezing the limiting member 3 and forcing it to deform, thereby reducing the force applied when installing the locking bolt 8.

[0045] The working principle of this utility model:

[0046] Insert the positioning rod 1 into the mounting holes on both sides of the trash can 14 so that both ends of the first rod section 15 in the positioning rod 1 are flush with the outer cross-section of the mounting holes of the trash can 14, thereby achieving the insertion and installation of the positioning rod 1 on the trash can 14;

[0047] Sleeve the limiting piece 13 into the second rod segment 16 so that one end of it fits in with the first rod segment 15, and then sleeve the limiting rod 2 so that the limiting member 3 is clamped between the positioning rod 1 and the limiting rod 2;

[0048] The first limit ring 4 is sleeved on the mounting step 9 on the limit rod 2, and then the bearing 6 is sleeved, so that the first limit ring 4 is clamped between the limit rod 2 and the bearing 6, so that the two ends of the first limit ring 4 are respectively in contact with the limit rod 2 and the inner ring of the bearing 6;

[0049] Install the runner 7 on the bearing 6 to achieve a plug-in connection between the runner 7 and the bearing 6, thereby achieving a mutually locked connection between the bearing 6 and the runner 7;

[0050] Then, the second limiting retaining ring 5 is sleeved on one end of the second rod segment 16 (that is, the end of the rotating wheel 7 away from the first limiting retaining ring 4), so that the second limiting retaining ring 5 abuts against the inner ring of the bearing 6, and finally the locking bolt 8 is installed in the mounting thread 10 formed on the second rod segment 16. The locking bolt 8 cooperates with the thread of the second rod segment 16 to lock and position the shaft limiting rod 2 on the second rod segment 16, so that it is clamped and limited on the positioning rod 1. The installation of the wheel set only requires the installation work that is compatible with the locking bolt 8, and the plug-in, locking, clamping and other limiting and positioning methods between different components of the wheel set are used to achieve convenient installation of the wheel set.
