[0025] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "inside", "outside", "front", "back", "horizontal", and "vertical" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0027] It should be noted that the terms “horizontal” and “vertical” in the present invention are used to describe a rough positional relationship, rather than a strict “horizontal plane” or “vertical plane”.

[0028] like Figures 1 to 7 FIG. 1 shows a preferred embodiment of a trash can anti-fall structure, comprising:

[0029] The back plate assembly 1 is extended in the vertical direction, and a rotation hole is provided at the lower end of the back plate assembly 1;

[0030] The counterweight block 3 is arranged on the back plate assembly 1. The counterweight block 3 is provided with a mounting hole, and the rotation hole is directly opposite to the mounting hole;

[0031] Rotating shaft 2, both ends of which pass through the mounting hole and the rotation hole, and the rotating shaft 2 connects the back plate assembly 1 and the counterweight 3;

[0032] The limiting plate 4 is arranged at the lower end of the back plate assembly 1. The limiting plate 4 is connected to the back plate assembly 1. The counterweight block 3 can contact the limiting plate 4. The limiting plate 4 is used to limit the movement range of the counterweight block 3 to ensure that the counterweight block 3 can contact the limiting plate 4, thereby effectively preventing the trash can hook 7 from falling off.

[0033] Furthermore, as a preferred embodiment, when the trash can hanging ears 7 are respectively leaning against the two back plate assemblies 1, the counterweight 3 is in the initial state; then the back plate assembly 1 is flipped to 45 degrees by the external flipping mechanism, at this time the trash can hanging ears 7 enter the rotating groove along the back plate 5 under the action of gravity, and at this time the counterweight 3 will swing a certain angle around the rotating axis 2 under the action of gravity to ensure that the trash can is safely fixed, and the trash can will not fall or fall off in this state; when the back plate assembly 1 is flipped to 90 degrees by the external flipping mechanism, the trash can is in a horizontal state at this time. The counterweight block 3 contacts the limit plate 4 under the action of gravity. At this time, the horizontal distance between the upper end of the counterweight block 3 and the back plate assembly 1 is smaller than the outer diameter of the trash can hanging ear 7. An opening smaller than the size of the trash can hanging ear 7 is formed between the counterweight block 3 and the back plate assembly 1, thereby effectively preventing the trash can hanging ear 7 from falling out; when the back plate assembly 1 is flipped to 135° by the external flipping mechanism, the trash can hanging ear 7 will be firmly clamped between the back plate assembly 1 and the counterweight block 3, and even in the falling state, it cannot escape the obstruction of the limit plate 4, thereby ensuring the safe storage and unloading of the trash can.

[0034] Further, as a preferred embodiment, the backrest assembly 1 includes: two backrests 5, each backrest 5 is provided with a rotating hole at the lower end, the counterweight 3 is arranged between the two backrests 5, the rotating shaft 2 connects the two backrests 5 and the counterweight 3, and the limit plate 4 is connected to the two backrests 5.

[0035] Furthermore, as a preferred embodiment, the support plate 5 has an inclined portion 6 , the rotation hole is provided at one end of the inclined portion 6 , and the limiting plate 4 is provided at the other end of the inclined portion 6 .

[0036] Furthermore, as a preferred embodiment, the counterweight 3 includes: a first part and a second part, the first part is fixedly connected to the second part, the mounting hole is provided in the first part, and the second part can contact with the limiting plate.

[0037] Furthermore, as a preferred embodiment, the first part and the second part are both plate-like structures, the cross-section of the first part is trapezoidal, the first part has an inclined edge, the second part has an arc edge and a straight edge, the straight edge can contact the limiting plate 4, and the straight edge is fixedly connected to the inclined edge.

[0038] Furthermore, as a preferred embodiment, the outer contour of the first part is larger than the outer contour of the second part, and the weight of the first part is greater than the weight of the second part, so that the counterweight block 3 can swing around the rotating axis 2 at a certain angle under the action of its own gravity when rotating with the back plate 5.

[0039] Furthermore, as a preferred embodiment, the first part and the second part are preferably an integrated structure.

[0040] Furthermore, as a preferred embodiment, the sides of the two support plates 5 that are close to each other are fixedly connected to the external turning mechanism.

[0041] Furthermore, as a preferred embodiment, the two support plate assemblies 1 are respectively welded to the two ends of the external flip mechanism, the left hanging ear and the right hanging ear of the trash can are respectively leaned on the two support plate assemblies 1, and the trash can hanging ear 7 can move between the two support plates 5.

[0042] Furthermore, as a preferred embodiment, nuts are sleeved on the outer peripheries of both ends of the rotating shaft 2 , and the rotating shaft 2 is connected to the back plate assembly 1 via the nuts.

[0043] Furthermore, as a preferred embodiment, the rotating shaft 2 is threadedly connected to the nut. Further, by tightening the nut, the rotating shaft 2 will not fall off from the back plate assembly 1, and the counterweight 3 can rotate around the rotating shaft 2.

[0044] Furthermore, as a preferred embodiment, the distance between the two supporting plates 5 is greater than the width of the counterweight 3 along the axis of the rotating shaft, and the counterweight 3 can rotate between the two supporting plates 5 through the rotating shaft 2.

[0045] Furthermore, as a preferred embodiment, each support plate 5 is provided with an opening, and the two openings are connected to form a rotation groove. Furthermore, the trash can hanging ear 7 can slide in the rotation groove.
