[0025] To better understand the purpose, structure and function of the present utility model, the following further describes in detail a toner cartridge with an internal double-sealing structure according to the present utility model with reference to the accompanying drawings.

[0026] As Figures 1-6 shown, a toner cartridge with an internal double-sealing structure according to the present utility model includes a toner cartridge body 1. A cartridge 2 is installed on the surface of the toner cartridge body 1. A cover plate 3 is installed on the surface of the cartridge 2. An external thread ring 10 is welded on the surface of the cover plate 3. An internal thread cover 11 is sleeved on the surface of the external thread ring 10. A sealing plug 12 is adhesively bonded inside the internal thread cover 11. The sealing plug 12 is embedded inside the internal thread ring. An internal thread seat 18 is fixedly connected to the surface of the internal thread cover 11. By installing the external thread ring 10 and the internal thread seat 18, the external thread ring 10 can provide a fixing effect for the sealing plug 12, and the internal thread seat 18 can provide a fixing effect for the sealing ring 14, so that the sealing stability is relatively strong. A lead screw 20 is sleeved inside the internal thread seat 18. A stop piece 13 is welded at one end of the lead screw 20. A sealing ring 14 is installed on the surface of the stop piece 13. The surface of the sealing ring 14 is attached to the back of the cover plate 3. By installing the sealing plug 12 and the sealing ring 14, the sealing plug 12 and the sealing ring 14 can provide sealing effects for both ends of the external thread ring 10, so that the cartridge 2 has an internal double-sealing structure and has relatively strong sealing performance during use.

[0027] A second card slot 16 is opened on the surface of the stop piece 13. A clamping ring 15 is fixedly connected to the surface of the sealing ring 14. The clamping ring 15 is located inside the second card slot 16. By installing the clamping ring 15 and opening the second card slot 16, a replaceable effect can be provided for the sealing ring 14. When the sealing ring 14 needs to be replaced, the sealing ring 14 can be directly taken out and a intact sealing ring 14 can be installed on the stop piece 13 until the clamping block 8 is embedded inside the card slot. It is very convenient to use.

[0028] A clamping frame 7 is fixedly connected to the back of the cover plate 3. A clamping block 8 is fixedly connected to the surface of the clamping frame 7. A sealing frame 6 is provided on the surface of the clamping frame 7. A first card slot 9 is opened inside the sealing frame 6. The clamping block 8 is located inside the first card slot 9. By installing the sealing frame 6, the sealing frame 6 can provide a sealing effect for the gap between the cover plate 3 and the cartridge 2, so that the toner inside the cartridge 2 will not leak out and has relatively strong sealing performance during use.

[0029] A fixing frame 4 is welded on the surface of the cover plate 3, and a fixing frame 5 is welded on the surface of the ink cartridge 2. The fixing frame 4 penetrates through the fixing frame 5, and the fixing frame 5 is connected to the fixing frame 4 by bolts. By installing the fixing frame 5 and the fixing frame 4, when it is necessary to fix the cover plate 3, the fixing frame 4 and the fixing frame 5 can be fixed by bolts, and the stability is strong during use.

[0030] A limiting ring 17 is welded on the back of the cover plate 3. A retaining piece 13 is sleeved inside the limiting ring 17. The surface of the sealing ring 14 fits against the inner wall of the limiting ring 17. By installing the limiting ring 17, the limiting ring 17 can provide a limiting effect for the retaining piece 13, and by fitting against the sealing ring 14, the sealing performance can be further improved.

[0031] The other end of the lead screw 20 is welded with a grip ring 19. The retaining piece 13 is located inside the ink cartridge 2. By installing the grip, when it is necessary to rotate the lead screw 20, the force application point of the grip ring 19 can be utilized, and the lead screw 20 can be directly driven to rotate through the grip ring 19, which is very convenient during use.

[0032] The working principle of the toner cartridge with an internal double-sealing structure: When using the toner cartridge with an internal double-sealing structure, the cover plate 3 should be installed on the ink cartridge 2 first. At this time, the card frame 7 can be directly inserted into the ink cartridge 2 until the surface of the sealing frame 6 fits against the inner wall of the ink cartridge 2. At this time, the fixing frame 4 will penetrate through the fixing frame 5, and then the fixing frame 4 can be fixed inside the fixing frame 5 by bolts to fix the cover plate 3. After that, toner can be added to the ink cartridge 2. When adding toner to the ink cartridge 2, the toner can be directly added to the ink cartridge 2 through the external thread ring 10. When the toner addition is completed, the internal thread cover 11 can be installed on the surface of the external thread ring 10 until the sealing plug 12 is located inside the external thread ring 10. Then rotate the lead screw 20. Under the action of the internal thread seat 18, the retaining piece 13 can be driven to move, and then the sealing ring 14 can be driven to move. When the sealing ring 14 fits against the cover plate 3, it is okay. At this time, the external thread ring 10 can provide a fixing effect for the sealing plug 12, and the internal thread seat 18 can provide a fixing effect for the sealing ring 14, so that the sealing stability is strong, and the sealing plug 12 and the sealing ring 14 can provide sealing effects for both ends of the external thread ring 10, so that the ink cartridge 2 has an internal double-sealing structure and the sealing performance is strong during use.

[0033] It can be understood that the present invention is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present invention, various changes or equivalent replacements can be made to these features and embodiments. In addition, under the teaching of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present invention.
