[0035] Example 1

[0036] like Figures 1-5 As shown, a guide structure for a garbage bin includes: a rotating sleeve 1, a guide sleeve 2, a first guide disc 3, and a second guide disc 4. The rotating sleeve 1 is rotatably connected to a frame 5. The guide sleeve 2 is fitted onto the rotating sleeve 1 and is used to rotate and guide the bottom longitudinal beam of the garbage bin. The first guide disc 3 is mounted on the frame 5 and has a first guide body 301, which is in rotatable contact with one end face of the guide sleeve 2. The second guide disc 4 is mounted on the frame 5 and has a second guide body 401, which is in rotatable contact with one end face of the rotating sleeve 1. The first guide disc 3 and the second guide disc 4 position the integral structure formed by the rotating sleeve 1 and the guide sleeve 2 on the frame 5.

[0037] Specifically, such as Figure 2 As shown, the crossbeam at the rear of the frame 5 is connected to the lugs on the longitudinal beam of the frame 5. The two ends of the crossbeam extend outwards toward the lugs to form cylindrical connecting sections 6. The connecting sections 6 are used to rotatably connect to the rotating sleeve 1. The crossbeam is also used to hinge with the rear of the tilting frame.

[0038] Specifically, such as Figure 2 As shown, the rotating sleeve 1 has a first guide portion and a second guide portion. The second guide portion guides the longitudinal beam toward the first guide portion, and the first guide portion provides rotational support for the longitudinal beam. The first guide portion has a cylindrical shape, and the second guide portion has a conical shape with its small end connected to the first guide portion. When the position of the longitudinal beam at the bottom of the garbage bin shifts, the conical surface guides the longitudinal beam, causing it to gradually move toward the cylindrical shape during movement. By guiding the longitudinal beam's position with the second guide portion, the longitudinal beam's position can be corrected, allowing it to move onto the first guide portion, thereby adjusting the garbage bin to the center position of the frame 5.

[0039] Specifically, such as Figure 2As shown, the guide structure of the garbage can further comprises: a fixed sleeve 7 fixedly connected to the frame 5, and the rotating sleeve 1 is sleeved and rotated on the fixed sleeve 7. The fixed sleeve 7 is sleeved on the connecting section 6, and can be bolted, tightly fitted, threaded or fixed to the connecting section 6. The rotating sleeve 1 is also inserted into the inner hole of the guide sleeve 2 and positioned by the end plate in the guide sleeve 2, and can be fixedly connected to the rotating sleeve 1 by means of tight fit, bolt connection, welding, etc. The rotating sleeve 1 and the fixed sleeve 7 are made of wear-resistant materials, such as copper. By arranging the rotating sleeve 1 and the fixed sleeve 7 between the guide sleeve 2 and the connecting section 6, a rotating connection structure is formed by the rotating sleeve 1 and the fixed sleeve 7, so that wear occurs between the rotating sleeve 1 and the fixed sleeve 7, and no wear occurs between the guide sleeve 2 and the connecting section 6, thereby improving the wear resistance between the rotating structures and facilitating later maintenance and replacement operations.

[0040] Specifically, as shown in Figure 2 、 5 , the frame 5 is provided with a first oil hole 601, the fixed sleeve 7 is provided with a second oil hole 701, and the inner hole of the rotating sleeve 1 is provided with an oil groove 101. The second oil hole 701 communicates the first oil hole 601 and the oil groove 101. The first oil hole 601 comprises an axial hole and a radial hole. The axial hole is provided along the axis of the connecting section 6, and the port of the axial section is connected with a pressure injection oil cup. The radial hole is provided along the radial direction of the connecting section 6 and communicates with the axial section. The second oil hole 701 corresponds to the first oil hole 601. The fixed sleeve 7 is also provided with an inner ring groove 702 and an outer ring groove 703 at the second oil hole 701. The inner ring groove 702 facilitates the butt joint of the first oil hole 601 and the second oil hole 701, and the outer ring groove 703 facilitates the butt joint of the second oil hole 701 and the oil groove 101. The oil groove 101 is a spiral groove, so that the oil can be evenly applied to the contact surface of the fixed sleeve 7 and the rotating sleeve 1. By arranging the oil path, lubricating oil can be added to the rotating structure, thereby ensuring the rotation performance.

[0041] Specifically, as shown in Figure 2 , the guide structure of the garbage can further comprises: a nut 8 and a gasket 9. The nut 8 is a slotted nut, and the nut 8 is threadedly connected to the connecting section 6. The gasket 9 is sleeved on the connecting section 6 and arranged between the nut 8 and the end plate.

[0042] Specifically, as shown in Figure 3As shown, the first guide plate 3 further includes: a first plate body 302 and a first pressure cap 303. The first pressure cap 303 is connected to the first plate body 302 and restricts the rotation of the first guide body 301 within the first plate body 302. The first guide body 301 is a sphere. The first plate body 302 has a hemispherical groove corresponding to the sphere. The first pressure cap 303 has an arc-shaped through hole corresponding to the sphere. The gap between the spheres is set in the corresponding groove and through hole. The part of the sphere extends to the other side through the through hole. There are multiple first guide bodies 301 and they are evenly distributed on the same circumference with the axis of the first plate body 302 as the center line. The end plate has an annular groove with an arc-shaped cross section corresponding to the first guide body 301. When the guide sleeve 2 rotates, the first guide body 301 rolls in the annular groove.

[0043] Specifically, such as Figure 4 As shown, the second guide plate 4 also includes: a second plate body 402 and a second pressure cover 403. The second plate body 402 is bolted to the ear plate, and the second pressure cover 403 is connected to the second plate body 402. The second pressure cover 403 limits the rotation of the second guide body 401 to the second plate body 402. The second guide body 401 is a sphere. The second plate body 402 has a hemispherical groove corresponding to the sphere. The second pressure cover 403 has an arc-shaped through hole corresponding to the sphere. The gap between the spheres is set in the corresponding groove and through hole. The part of the sphere extends to the other side through the through hole. There are multiple second guide bodies 401 and they are evenly distributed on the same circumference with the axis of the second plate body 402 as the center line. The rotating sleeve 1 has an annular groove with an arc-shaped cross section corresponding to the second guide body 401. When the guide sleeve 2 rotates, the second guide body 401 rolls in the annular groove.

[0044] Specifically, such as Figure 3 , 4 As shown, the guiding structure of this type of trash can also includes: a first seal 10 and a second seal 11. The first seal 10 is disposed between the guide sleeve 2 and the first guide disc 3, and the second seal 11 is disposed between the guide sleeve 2 and the frame 5. Both the first seal 10 and the second seal 11 are sealing rings. A first sealing ring groove is formed around the connecting section 6 on the end face of the first disc 302, and the first sealing ring is inserted into the first sealing ring groove. A second sealing ring groove is formed around the connecting section 6 on the end face of the ear plate, and the second sealing ring is inserted into the second sealing ring groove. Since both the first seal 10 and the second seal 11 are located at the rotating position, both the first seal 10 and the second seal 11 need to be dynamic sealing rings. The first seal 10 and the second seal 11 prevent debris from entering the rotating structure, thereby improving the stability of the environment between the rotating parts and ensuring the durability and smoothness of the rotation performance.

[0045] like Figure 6When the hook arm drags the garbage can to move up or down, the longitudinal beam at the bottom of the garbage can contacts the surface of the guide sleeve 2, and the guide sleeve 2 is driven to rotate through friction, and in the rotating process of the guide sleeve 2, the rotating sleeve 1 rotates relative to the outer periphery of the fixed sleeve 7, so as to avoid the abrasion of the connection part of the guide sleeve 2 and the frame 5, and the guide sleeve 2 and the fixed sleeve 7 are made of wear-resistant material, so as to improve the service life of the rotating structure, the first guide disc 3 and the second guide disc 4 clamp the guide sleeve 2 on the connecting section 6, and rotate and position the rotating sleeve 1 and the guide sleeve 2, so as to improve the stability of the positioning of the guide sleeve 2 and the stability of the rotating process, so as to roll guide and support the movement of the longitudinal beam during the movement of the garbage can.
