For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figures 1 to 5As shown, the hook-arm type garbage bin of this embodiment comprises a bin body 1, on which a lifting lug 2 is provided, and between which a buffer mechanism 3 is provided, and the buffer mechanism 3 is used to mitigate the impact of the hook arm of the garbage truck on the bin body 1.

[0035] The hook-arm type garbage bin of this embodiment, when cooperating with the hook-arm type garbage truck for loading and unloading, the hook arm of the garbage truck extends to hook the lifting lug 2. Since a buffer mechanism 3 is provided between the box body 1 and the lifting lug 2, the hook arm of the garbage truck does not directly collide with the box body 1, but instead hits the buffer mechanism 3, and the buffer mechanism 3 buffers the impact of the hook arm of the garbage truck. The hook-arm type garbage bin of this embodiment prevents the hook arm of the garbage truck from directly hitting the box body 1 by providing a buffer mechanism 3 between the box body 1 and the lifting lug 2, thereby reducing the impact and protecting the garbage bin, thereby preventing the garbage bin from being damaged due to the impact. The structure is simple and the anti-collision effect is good.

[0036] Furthermore, if Figures 6 to 10 As shown, in this embodiment, the buffer mechanism 3 includes a first buffer plate 31, a support column 33, a buffer spring 34 and a stopper 35. The first end of the support column 33 is connected to the box body 1 and the second end is connected to the stopper 35. The first buffer plate 31 is slidably connected to the support column 33. The buffer spring 34 is sleeved on the support column 33 and is located between the box body 1 and the first buffer plate 31. When a collision occurs, the hook arm of the garbage truck directly collides with the first buffer plate 31. After the first buffer plate 31 is subjected to force, it slides along the support column 33 toward the box body 1 and squeezes the buffer spring 34. The buffer spring 34 buffers the instantaneous impact force and then transmits it to the box body 1 to reduce the impact, thereby protecting the box body 1; thereafter, the buffer spring 34 is reset to push the first buffer plate 31 outward along the support column 33. The stopper 35 limits the first buffer plate 31 to prevent the first buffer plate 31 from slipping out of the support column 33, and the structure is more reliable.

[0037] Furthermore, in this embodiment, the buffer mechanism 3 also includes a second buffer plate 32 fixedly connected to the box body 1, and the first end of the support column 33 is connected to the second buffer plate 32. Preferably, the support column 33 is a screw, the head of the screw is welded to the second buffer plate 32, and the limiter 35 is a limit nut and is arranged on the rod of the screw. By providing the second buffer plate 32, the box body 1 can be partially thickened to further improve reliability. The limit nut cooperates with the screw to facilitate the disassembly and replacement of the buffer spring 34 and the first buffer plate 31, etc., and extend the service life of the trash can.

[0038] Furthermore, in this embodiment, two second buffer plates 32 are provided and are respectively located at the upper and lower sides of the lifting ear 2. That is, the first buffer plate 31 is supported by support columns 33 at the upper and lower sides of the lifting ear 2, which can adapt to the impact of the hook arm of the garbage truck on the first buffer plate 31 at different upper and lower points, and the structure is more solid.

[0039] Furthermore, in this embodiment, support columns 33 are provided at both ends of the second buffer plate 32. Since support columns 33 are provided at both ends of the second buffer plate 32, and two second buffer plates 32 are provided and are respectively located at the upper and lower sides of the lifting ear 2, that is, support columns 33 are provided at the four corners of the first buffer plate 31, the structure is more solid and reliable.

[0040] Furthermore, in this embodiment, a guide hole 311 is provided on the first buffer plate 31, and the support column 33 is inserted into the guide hole 311. The guide hole 311 is a stepped hole and the maximum inner diameter is larger than the outer diameter of the stopper 35 to accommodate the stopper 35. The first buffer plate 31 is slidably connected with the support column 33 through the guide hole 311, and is more stable when sliding, so that the buffer spring 34 is subjected to a balanced force and has a better anti-collision effect; at the same time, an accommodation space 312 is formed in the guide hole 311 to accommodate the stopper 35, so that in the normal state, even if the first buffer plate 31 is in conflict with the stopper 35 under the action of the buffer spring 34, the stopper 35 will not protrude excessively from the surface of the first buffer plate 31, preventing the stopper 35 from being directly hit, and the structure is more reliable.

[0041] Furthermore, in this embodiment, the edge of the first buffer plate 31 is provided with a folded edge 313 bent toward the box body 1. The folded edge 313 can improve the rigidity of the first buffer plate 31, prevent the first buffer plate 31 from being deformed during impact, and improve the service life of the first buffer plate 31.

[0042] Furthermore, in this embodiment, the first buffer plate 31 is also provided with an avoidance groove 314 for avoiding the lifting lug 2. The avoidance groove 314 can prevent the lifting lug 2 from swinging and interfering with the first buffer plate 31 during the lifting process, thereby reducing damage to the first buffer plate 31 and the lifting lug 2, and the structure is simple and effective.

[0043] Furthermore, in this embodiment, the box body 1 is provided with a first box door 11 and a second box door 12 hinged to the box body 1, the first box door 11 is arranged at the front and rear ends of the box body 1 opposite to the lifting ear 2, and a plurality of second box doors 12 are provided and are respectively provided at the left and right sides of the box body 1. The first box door 11 is arranged opposite to the lifting ear 2, and the arm hook of the garbage truck hooks the lifting ear 2 and lifts up, and the garbage in the box body 1 can fall out of the first box door 11 under the action of gravity, which is convenient for unloading; there are a plurality of second box doors 12, which can be flexibly selected to facilitate garbage collection.

[0044] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model has been disclosed as above in the preferred embodiment, it is not used to limit the utility model. Any technician familiar with the field can make many possible changes and modifications to the technical solution of the utility model by using the methods and technical contents disclosed above without departing from the spirit and technical solution of the utility model, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments based on the technical essence of the utility model without departing from the content of the technical solution of the utility model, still fall within the scope of protection of the technical solution of the utility model.
