The snap connection between the bottom 4 and the body 3 of the barrel makes the connection convenient and facilitates the mold manufacturing of the two.

The arrangement of the inner partition 2 is as follows: the barrel body 3 is provided with longitudinal ribs 31, and the inner partition 2 and the longitudinal ribs 31 are limited to be located between the longitudinal ribs 31 and the side walls of the barrel 1. The "longitudinal" mentioned here refers to the depth direction of the trash can. Supported by the bottom of the trash can, the rotating arm of the inner partition 2 is relatively large, and the longitudinal ribs 31 are provided to prevent the inner partition 2 from falling over.

Further, in this embodiment, the bottom 4 of the barrel is provided with a transverse rib 41, and the inner partition 2 and the transverse rib 41 abut and are limited to be located between the transverse rib 41 and the side wall of the barrel 1. The transverse ribs 41 are perpendicular to the longitudinal ribs 31, which increase the restriction of the inner partition 2 in another direction, thereby stably restricting the inner partition 2 to the rear of the barrel 1.

Further, in this embodiment, the installation structure of the trash can further includes screws 13. The bottom 4 of the barrel and the inner partition 2 are connected by screws 13.

By adding the third groove, the embedding point during the closing process of the protrusion 6011 is increased, and the stopping point of the shaft 1 can be formed at the third groove, and the shaft 1 between the third groove and the second groove 6022 is further reduced. The rotation speed of the barrel cover 6 is more stable.

In this embodiment, the implementation between the grooves and the protrusions 6011 is as follows: the first grooves 6021 are two symmetrically distributed. The second grooves 6022 are two symmetrically distributed. The protrusions 6011 are two symmetrically distributed.

The second end of the rod 101 is formed with a lower end surface 1021 on which the second timing belt 1032 is installed. At this time, the rod 101 is located between the two first timing belts 1031, and both ends are driven by the two first timing belts 1031 at the same time.

The fixing of the pressing plate 102 and the rod 101 may be a snap connection or a fastener connection. In this embodiment, the pressure plate 102 is formed with a threaded through hole 1022, the rod 101 is formed with a threaded hole 1013 matching the threaded through hole 1022, and the pressure plate 102 and the rod 101 are fastened with screws 103.

Preferably, this embodiment further includes a cross bar 105. The cross rod 105 and the rod 101 are arranged to move in a cross direction. The rod 101 includes an upper end surface 1015 and a lower end surface 1016. The cross bar 105 is provided between the upper end surface 1015 and the lower end surface 1016. Therefore, the rod 101 wraps the cross rod 105, which can prevent the bag from being trapped during the closing process.

The pressing plate 102 may be fixedly connected with the upper end surface 1015 and the lower end surface 1016, or the pressing plate 102 may be fixedly connected with the lower end surface 1016. In this embodiment, the pressing plate 102 is fixedly connected to the upper end surface 1015.

Preferably, the upper end surface 1015 and the lower end surface 1016 are flush against the end surfaces of the garbage bag.

Preferably, the trash can further includes a guide rail 104. The guide rail 104 is arranged in parallel with the first timing belt 1031, the rod 101 is provided with a through hole 1014, and the rod 101 passes through the guide rail 104 and is slidably connected to the guide rail 104. Therefore, when the rod 101 is driven by the first timing belt 1031 to move, it slides along the guide rail 104.
