Description

Technical Field

[0001] The utility model relates to the technical field of printer accessory structures, in particular to a toner cartridge protection structure and a toner cartridge thereof. Background Art

[0002] Toner cartridges, also known as photosensitive drums, are generally composed of a basic substrate made of aluminum and a photosensitive material coated on the substrate. In laser printers, most of the imaging components are concentrated in the toner cartridge, and the quality of printing is actually largely determined by the toner cartridge. The toner cartridge is equipped with structural components such as a powder bin, a magnetic roller, and a photosensitive drum. Specifically, under the irradiation of laser, a latent image is formed on the surface of the photosensitive drum, and the toner is adsorbed on the latent image to form a real image, and finally the image is transferred to the paper to complete the printing. Since the photosensitive drum structure is exposed to the toner cartridge, in order to prevent the exposed part of the photosensitive drum from being contaminated by external dust, a protective structure is usually provided on the toner cartridge to cover the photosensitive drum during transportation to prevent the photosensitive drum from being contaminated by dust and affecting the printing effect. When the toner cartridge is in working state, the lifting structure on the printer will lift the protective structure to expose the photosensitive drum. Therefore, the existing toner cartridge protection structure is provided with a linkage mechanism that cooperates with the printer lifting structure, and its structure and manufacturing process are relatively complex. In the event of a failure, the toner cartridge cannot be protected, which affects the service life of the printer. Summary of the invention

[0033] Reference Figure 3 The embodiment of the utility model also provides a toner cartridge, including a main body 400 and the toner cartridge protection structure as described above; one end of the main body 400 is provided with a card slot 410 that cooperates with the fixing part 200, the other end of the main body 400 is provided with a rotating shaft 420 that cooperates with the through hole 320, and a protrusion 430 is provided under the rotating shaft 420; the main body 400 is inserted into the buckle 310 through the protrusion 430 and is fixedly connected to the protective cover 100.

[0034] By setting the fixing part 200 and the buckling part 300, the fixing part 200 is inserted into the card slot 410, and the protrusion 430 is inserted into the buckle 310, so that the protective cover 100 can be stably and accurately installed on the main body 400, ensuring the connection stability between the protective cover 100 and the main body 400, and improving the installation convenience and working stability of the toner cartridge protection structure; by setting the cover plate 110 and the shielding part 111, it is ensured that the protective cover 100 can fit the opening position of the toner cartridge, effectively increasing the protection area of ​​the protective cover 100, and improving the protection performance and working stability of the toner cartridge.

[0035] The working principle of the utility model is further explained below.

[0036] During use, a toner cartridge protection structure of corresponding specifications is used according to the size of the main body 400, so that when the fixing part 200 is inserted into the card slot 410, the rotating shaft 420 can be inserted into the through hole 320, and at the same time, the protrusion 430 is inserted into the buckle 310, so that the protective cover 100 fits the main body 400. Since the fixing parts 200 and the pressing parts 300 at both ends of the protective cover 100 are fixed on the main body 400, it can ensure that the protective cover 100 can completely cover the exposed position of the photosensitive drum structure on the main body 400, that is, the protective cover 100 can completely cover the opening position on the main body 400.

Especially during the transportation and storage of the main body 400, the fixing parts 200 and the pressing parts 300 at both ends of the protective cover 100 can effectively use the original rotating shaft 420 and the protrusion 430 on the main body 400 for fixing, preventing the protective cover 100 from falling off from the main body 400. When the main body 400 needs to be installed inside the printer, it is only necessary to pull open the buckle 310 so that the protrusion 430 leaves the buckle 310; then pull up the side of the protective cover 100 close to the buckle 310 to disengage the fixing portion 200 from the through hole 320; finally, pull up the side of the protective cover 100 close to the fixing portion 200 to disengage the rotating shaft 420 from the card slot 410, and the toner cartridge protection structure on the main body 400 can be quickly disassembled to ensure that the toner cartridge can be quickly installed and used.

[0037] From the above description, it can be seen that the toner cartridge protection structure and toner cartridge of the present invention can stably and accurately install the protective cover 100 on the main body 400 by setting the fixing part 200 and the buckling part 300, the fixing part 200 is inserted into the card slot 410, and the protrusion 430 is inserted into the buckle 310, thereby ensuring the connection stability between the protective cover 100 and the main body 400, and improving the installation convenience and working stability of the toner cartridge protection structure; by setting the cover plate 110 and the shielding part 111, it is ensured that the protective cover 100 can fit the opening position of the toner cartridge, effectively increasing the protection area of ​​the protective cover 100, and improving the protection performance and working stability of the toner cartridge.
