[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figure 1 and Figure 4 As shown, in this embodiment, a sealing structure for the powder filling port of a toner cartridge includes a shell 1, a shell 2 is provided on the right side of the shell 1, a plurality of tank bodies 3 are clamped in the shell 1, a powder filling tube 4 is fixedly connected above the tank body 3, a sealing plate 5 is slidably connected in the powder filling tube 4, a slide groove 8 is provided above the shell 2, a plurality of adjustment structures 6 are connected above the shell 2, the adjustment structure 6 is slidably connected in the slide groove 8, the adjustment structure 6 is connected to the sealing plate 5, an inlet groove 9 is provided in the sealing plate 5, a plurality of cleaning structures 7 are provided above the shell 1, the adjustment structure 6 includes a sleeve plate 601 and a slider 602, a guide rod 603 is slidably connected in the sleeve plate 601, and a spring 604 is connected to the outer sleeve of the guide rod 603.

[0021] like Figure 1 and Figure 3 As shown, the tank body 3 is clamped in the shell 2, the shell 1 is clamped with the shell 2, the powder injection tube 4 is clamped in the shell 1, the powder injection tube 4 is clamped in the shell 2, the slider 602 is fixedly connected to the bottom of the sealing plate 5, the slider 602 is slidably connected in the slide groove 8, the sleeve plate 601 is fixedly connected to the top of the shell 2, one end of the guide rod 603 is connected to the sealing plate 5, and the sealing plate 5 is connected to the sleeve plate 601 through the spring 1 604.

[0022] By setting the slide groove 8 and the guide rod 603, a pulling force is applied to the guide rod 603, and the guide rod 603 will pull the slider 602 under the sealing plate 5 to slide in the slide groove 8. When the sealing plate 5 moves, it will drive the spring 1 604 to deform through the sleeve plate 601, so that the slide groove 8 and the guide rod 603 play a certain guiding role in the movement of the sealing plate 5, avoiding the phenomenon of the sealing plate 5 being offset when moving.
