[0034] In order to make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0035] The present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0036] See Figures 1 - 18 , the large - cover flipping and opening - closing structure of this trash can includes a large cover 1 and a barrel body 2. The large cover 1 and the barrel body 2 flip and open - close relative to each other, and a guiding and suspended - movement mating part is provided between them. When the large cover 1 and the barrel body 2 flip and open - close, the guiding and suspended - movement mating part realizes guiding and hovering at any angle.

[0037] In this embodiment, by using the guiding and hovering functions of the guiding and suspended - movement mating part, when the large cover 1 flips and opens - closes relative to the barrel body 2, it can realize guiding opening and closing and hovering at any angle, so that the large cover 1 can stably flip and open - close on the barrel body 2, avoiding the problem of shaking when the large cover 1 flips and opens - closes. At the same time, the large cover 1 can also hover on the barrel body 2 at any flipping angle, not only preventing the large cover 1 from automatically returning to the closed position after being opened and ensuring the smooth opening of the large cover 1, but also enabling the user to freely open and close the flipping angle of the large cover 1 relative to the barrel body 2 according to the usage requirements, thereby improving the user experience.

[0038] The guiding and suspended - movement mating part includes a guide groove 3 and a sliding member 4. When the large cover 1 and the barrel body 2 flip and open - close, the sliding member 4 guides and slides along the track of the guide groove 3 and stops at any time.

[0039] The sliding member 4 and the guide groove 3 are in frictional fit, concave - convex fit, magnetic - adsorption fit, or any combination of the above to achieve stepless hovering or step - by - step hovering at any angle when the large cover 1 and the barrel body 2 flip and open - close.

[0040] In this embodiment, the sliding member 4 is located in the guiding groove 3, and there is a dimensional difference between the two, so as to achieve an interference friction type positioning fit. Or there are positions with concave-convex fits between the two, so as to achieve a concave-convex type positioning fit. Or there are magnetically attracting components between the two, so as to achieve a magnetic attraction type positioning fit.

[0041] The guiding groove 3 and the sliding member 4 correspond to each other and can be arbitrarily arranged on the large cover 1 and the barrel body 2 according to production and assembly requirements. That is, the guiding groove 3 is arranged on the large cover 1 and the sliding member 4 is arranged on the barrel body 2, or the guiding groove 3 is arranged on the barrel body 2 and the sliding member 4 is arranged on the large cover 1.

[0042] In this embodiment, it is preferably to adopt a friction method to realize the fit between the guiding groove 3 and the sliding member 4. At the same time, in order to avoid damage caused by friction between the sliding member 4 and the guiding groove 3, the contact position between the sliding member 4 and the guiding groove 3 has soft elasticity, and the two perform friction fit through the soft elastic contact position to realize the sliding stop of the two at any time.

[0043] Since the contact position between the sliding member 4 and the guiding groove 3 has soft elasticity, when the large cover 1 and the barrel body 2 are flipped and opened and closed, the sliding member 4 and the guiding groove 3 can have soft elastic interference deformation, so as to realize guiding sliding and stop at any time.

[0044] Specifically, the guiding groove 3 is arc-shaped and arranged on the barrel body 2, the sliding member 4 is a soft elastic member and protrudes on the large cover 1, the size of the sliding member 4 is larger than the inner size of the guiding groove 3, and the sliding member 4 performs elastic friction type guiding sliding along the track of the guiding groove 3 and stops at any time when the large cover 1 and the barrel body 2 are flipped and opened and closed.

[0045] In this embodiment, the sliding member 4 is a rubber part, which has soft elasticity and at the same time has a size larger than the inner size of the guiding groove 3. Therefore, the sliding member 4 can perform soft elastic deformation in the guiding groove 3 and can also be interference-fitted in the guiding groove 3, so as to realize elastic friction type guiding sliding and stop in the guiding groove 3 at any time.

[0046] The lower end of the guiding groove 3 is open and forms an opening part 5, the upper end is closed and provided with a receiving part 6, the inner size of the receiving part 6 is larger than the inner size of the guiding groove 3 and smaller than the size of the sliding member 4, and a protruding part 7 is arranged between the guiding groove 3 and the receiving part 6.

[0047] A rotating part 8 is arranged on the barrel body 2, a rotating fitting part 9 is arranged on the large cover 1 and is rotationally fitted with the rotating part 8 through the rotating fitting part 9. The guiding groove 3 is arranged in an arc shape along the periphery of the rotating part 8, and the sliding member 4 is positioned on one side of the rotating fitting part 9.

[0048] The large cover 1 is provided with a positioning hole 10, and the sliding member 4 is provided with a positioning portion 11. One end of the sliding member 4 at least partially extends outside the positioning hole 10 and is positioned on the positioning hole 10 through the positioning portion 11. A positioning member 12 is also fixedly provided on the large cover 1, and the positioning member 12 relies on the other end of the sliding member 4 for positioning.

[0049] An assembly portion 13 is provided on the barrel mouth side of the barrel body 2. An assembly mating portion 14 is provided on one side of the large cover 1 and is cooperatively connected with the assembly portion 13 through the assembly mating portion 14. The guiding groove 3 and the rotating portion 8 are provided on the assembly portion 13, and the sliding member 4 and the rotating mating portion 9 are provided on the assembly mating portion 14.

[0050] In this embodiment, an adapter 15 is provided between the large cover 1 and the barrel body 2. The shape of the adapter 15 is equivalent to the shape of the cover opening of the large cover 1 and the shape of the barrel mouth of the barrel body 2. At the same time, the adapter 15 is provided with an adapter opening communicating with the cover opening and the barrel mouth. The adapter 15 is fixed on the barrel mouth of the barrel body 2 by means of snap connection or fasteners, etc.

[0051] The assembly portion 13 is a boss and is provided at the rear side of the adapter 15. There are two guiding grooves 3 and two rotating portions 8, which are located on both sides of the assembly portion 13. The assembly mating portion 14 is a groove and is provided at the rear side of the large cover 1. There are two sliding members 4 and two rotating mating portions 9, which are located on both sides of the assembly mating portion 14.

[0052] During assembly, the assembly portion 13 and the assembly mating portion 14 are in concave-convex fit. One of the rotating portion 8 and the rotating mating portion 9 is convex and the other is concave, and the two are in socket-type rotational fit, or both are rotating holes and are rotatably fitted with each other through a rotating shaft. The sliding member 4 enters the guiding groove 3 from bottom to top through the opening portion 5. In addition, since the bottom position of the front side wall of the guiding groove 3 is higher than the bottom position of the rear side wall of the guiding groove 3, the sliding member 4 can be stably guided into the guiding groove 3. Moreover, the guiding grooves 3 and the rotating portions 8 on both sides cooperate with the sliding members 4 and the rotating mating portions 9 on both sides respectively, which can improve the flipping and opening / closing stability of the large cover 1 and avoid problems such as swinging and shaking of the large cover 1 during opening and closing.

[0053] Using the adapter 15 to realize the transfer and assembly between the large cover 1 and the barrel body 2 is not only convenient for production assembly and daily maintenance, but also can improve the assembly stability between components, and has strong practicability.

[0054] In addition, when the large cover 1 is flipped and opened relative to the barrel body 2 to the terminal position, the sliding member 4 can be limited in the accommodating portion 6. At the same time, by using the limiting effect of the protruding portion 7, the sliding member 4 can be positioned in the accommodating portion 6 without external force and will not return to the guiding groove 3 again, so as to ensure that the large cover 1 can be positioned at the terminal position on the barrel body 2.

[0055] In this embodiment, a positioning and assembling platform 16 is provided on the large cover 1. The positioning and assembling platform 16 is inside the positioning hole 10. The positioning member 12 and the positioning and assembling platform 16 are fixedly connected to each other by means of snap connection or fasteners. The side part of the positioning member 12 relies on the sliding member 4, and at the same time, the sliding member 4 is also positioned by the positioning portion 11 to effectively ensure that the sliding member 4 can be stably assembled on the positioning hole 10.
