In addition, the elastic structure is arranged below the barrel inner container 4, so that the up-and-down operation of the barrel inner container 4 is more gentle.

Preferably, the garbage can further comprises a second can cover locking mechanism, the second can cover locking mechanism comprises a second can cover locking connecting rod 13, one end of the second can cover locking connecting rod is hinged to the can inner container 4, and the middle of the second can cover locking connecting rod is hinged to the can body; the bottom end of the second barrel cover locking damping rod 14 is hinged with the other end of the second barrel cover locking connecting rod 13, the top end of the second barrel cover locking damping rod 14 is hinged with the barrel cover 1, and the hinged position of the second barrel cover locking damping rod 14 and the barrel cover 1 and the opening and closing end of the barrel cover 1 are respectively positioned on two sides of the hinged position of the barrel cover 1 and the barrel body 2; when the bucket liner 4 moves downwards, the second bucket cover locking connecting rod 13 drives the second bucket cover locking damping rod 14 to rotate inwards, and then the opening and closing end of the bucket cover 1 is driven to be buckled on the bucket body downwards.

As shown in fig. 1, when the inner container 4 is placed on the base 3 through the elastic structure, under the self-gravity of the inner container 4 and the gravity of the stored waste, the inner container 4 compresses the elastic structure to move downward, and synchronously drives the second lid locking link 13 to move downward together with the hinged end of the inner container 4, at this time, the second lid locking link 13 rotates around the hinged point of the second lid locking link 13 and the can body, and the second lid locking link 13 further drives the second lid locking damping rod 14 to move upward, so that the opening and closing end of the can lid 1 is closed under the lever action formed by the hinged position of the second lid locking damping rod 14 and the can lid 1 (i.e. the lid locking damping rod fixing hinge 16) and the hinged position of the can lid 1 and the can body 2 (i.e. the can lid fixing hinge 15), and the self-locking function of the trash can.

That is to say, the utility model discloses utilize first bung locking mechanical system and second bung locking mechanical system to realize 1 dual self-locking function of bung, bung 1's the reliability of closing is better. Of course, the present application may also include only the first bung locking mechanism.

As shown in fig. 1, the tub cover 1 is connected with the tub body 2 through a tub cover fixing hinge 15, and the tub cover 1 is connected with the second tub cover locking damping bar 14 through a tub cover locking damping bar fixing hinge 16. During installation, after the barrel cover 1 and the barrel cover fixing hinge 15 on the upper edge of the barrel body 2 are connected, the upper end of the second barrel cover locking damping rod 14 and the barrel cover locking damping rod fixing hinge 16 on the barrel cover 1 are connected, and then the lower end of the second barrel cover locking damping rod 14 and the second barrel cover locking connecting rod 13 are connected.

In order to facilitate the opening of the barrel cover 1, the barrel cover 1 opening mechanism comprises a barrel cover opening connecting screw rod 18 which is movably arranged on the barrel cover 1 along the horizontal direction, and a first locking head 20 is arranged on the barrel cover opening connecting screw rod 18; the barrel cover opening connecting screw rod 18 is driven to move along the horizontal direction so that the first locking head 20 is separated from the opening handle 5 of the second locking head 21, and the opening handle 5 is hinged in a handle mounting groove 24 at the top of the barrel cover 1 and is hinged with the barrel cover opening connecting screw rod 18 through a synchronous rotating arm.

As shown in fig. 14-17, the opening handle 5 is installed in the handle installation groove 24, one end is connected with the opening handle fixing hinge 17 on the barrel cover 1, and the other end is connected with the barrel cover opening connecting screw rod 18 through the synchronous rotating arm.

In this embodiment, the first locking head 20 is connected to the opening handle 5 through the lid opening connecting screw rod 18, and when the opening handle 5 is pulled upward, the lid opening connecting screw rod 18 is driven to move horizontally in a direction (i.e., right side in fig. 14) away from the second locking head 21, so that the first locking head 20 is separated from the second locking head 21, and the lid 1 is unlocked, thereby opening the lid 1.

This embodiment is opened connecting screw rod 18 drive first locking head 20 horizontal migration through opening handle 5 and bung, and is convenient laborsaving, of course, this application can also directly set up the button of dialling that the horizontal direction can be stirred to realize the effect of the first locking head 20 horizontal migration of same drive. It can be understood that the opening mechanism of the barrel cover 1 may also be a handle for driving the second locking head 21 to move upwards, so as to achieve the same effect of unlocking the first locking head 20 and the second locking head 21 when the barrel cover 1 needs to be opened, and the present invention is not limited in this respect.

In a further technical scheme, the opening mechanism of the barrel cover 1 further comprises two horizontal movement limiting plates 23 for limiting the horizontal movement position of the barrel cover opening connecting screw rod 18, and the horizontal movement limiting plates 23 are arranged on the barrel cover 1; and the locking head return spring 19 can drive the barrel cover opening connecting screw rod 18 to move towards the direction close to the second locking head 21 when the barrel cover opening connecting screw rod is deformed, and the locking head return spring 19 is sleeved on the barrel cover opening connecting screw rod 18.

In the embodiment, after the opening handle 5 is loosened, the elastic force of the locking head return spring 19 drives the barrel cover opening connecting screw rod 18 to horizontally move towards the direction (namely, the left side in fig. 14) close to the second locking head 21, so as to drive the opening handle 5 to return to the original position, so that the first locking head 20 can return to the position where the first locking head 21 can be meshed, and when the barrel cover 1 is closed, the self-locking of the barrel cover 1 can be realized again. Handle 5 is opened in the operation when this application only need open bung 1, facilitate the use. Of course, the present application can also drive the first locking head 20 to move in two directions by rotating the opening handle 5 in different directions.

During assembly, after the opening handle 5 is arranged at the position of a handle mounting groove 24 on the barrel cover 1, the opening handle is connected with the opening handle fixing hinge 17, the locking head return spring 19 is arranged between the two horizontal movement limiting plates 23, the barrel cover opening connecting screw rod 18 sequentially penetrates through the barrel cover opening connecting screw rod limiting hole 27, the horizontal movement limiting plate 23 and the locking head return spring 19 and is fixedly connected with the first locking head 20, the length of the barrel cover opening connecting screw rod 18 is adjusted, and therefore the first locking head 20 and the second locking head 21 can be stably and freely meshed in the horizontal direction.

In order to facilitate the locking heads to return to the self-locking position, the first locking head 20 is provided with a sliding inclined surface, the second locking head 21 is provided with a guiding inclined surface, and when the barrel cover 1 is closed, the first locking head 20 slides along the guiding inclined surface to a position below the second locking head 21 through the sliding inclined surface.
