Description

Technical Field

[0001] This utility model relates to the field of toner cartridges, and in particular to a toner cartridge with a novel drum core protection structure. Background Technology

[0002] Laser printers are widely used not only in businesses, schools, and government agencies, but also in homes. They offer fast printing speeds, high resolution, and significantly lower consumable costs compared to inkjet printers. The toner cartridge is a crucial component of the printer. Directly opposite the drum core, there's a section where the drum core is exposed, which is the primary area for inkjet printing. This section is protected by a cover when the cartridge is not installed to prevent damage to the drum core during transport, thus ensuring print quality. However, this protective cover is typically removed before using the cartridge, making it prone to loss and inconvenient for secondary transport or repair. Some protective covers, even those with a rotating or sliding design, suffer from issues such as accidental repositioning after opening, large size, and positional interference. Therefore, improvements are necessary. Utility Model Content

[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a drum core protective cover that can be flipped open or closed. When opened, it occupies very little space, is not likely to interfere with other printing components, and the protective cover can be firmly fixed. The position of the protective cover is very secure whether during transportation or printing.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] A toner cartridge with a novel drum core protection structure includes a toner cartridge shell, a drum core body disposed inside the toner cartridge shell, and a protective cover for protecting the drum core body.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1 to 6 The present invention preferably provides a toner cartridge with a novel drum core protection structure, including a toner cartridge shell 1, a drum core body 11 disposed inside the toner cartridge shell 1, and a protective cover 12 for protecting the drum core body 11. A cover mounting part 2 is provided on the toner cartridge shell 1, and a photosensitive port 3 is provided on the cover mounting part 2 that can be closed or opened by the protective cover 12. Slots 4 are provided on the left and right sides of the cover mounting part 2, and a swing connector 5 is provided in each slot 4 to be hinged to the protective cover 12. Hollow fasteners 6 are provided on the left and right sides of the protective cover 12, and a mounting mating part 7 is provided on the cover mounting part 2 for snapping into the hollow fasteners 6 to achieve damping engagement. The cover mounting section is located on the side of the drum shell near the drum core. The photosensitive port is located on the lower half of the cover mounting section. The drum core can be connected to the printer through the photosensitive port. When not connected, the photosensitive port is closed by the protective cover. When opening, pull the protective cover out with a little force to allow the hollow fastener to disengage from the mounting mating part. The protective cover can then disengage from the photosensitive port. Due to the setting of the swing connector, the protective cover can be flipped upward and moved until it is closed on the upper half of the cover mounting section, exposing the photosensitive port and allowing the hollow fastener to snap into the mounting mating part for installation and fastening.

[0022] In this invention, the cover mounting portion 2 is trapezoidal in shape, protruding from one side of the toner cartridge housing 1. The photosensitive port 3 is located on the lower half of the cover mounting portion 2, and the slot 4 is located on the middle section plane of the left and right sides of the cover mounting portion 2. The trapezoidal shape facilitates the installation and removal of the protective cover. Since the photosensitive port is located on the lower half of the cover mounting portion, the upper half can be used for installation after the protective cover is opened. The slot allows the swing connector to be installed within it, reducing the exposed protective cover caused by the swing connector.

[0023] The protective cover 12 described in this invention is obtuse-angled and can fit into the trapezoidal obtuse angle of the cover mounting part 2. The obtuse angle of the protective cover is consistent with the trapezoidal obtuse angle of the cover mounting part, so the protective cover can be installed and fitted into the upper and lower obtuse angles of the cover mounting part, reducing the space occupied by the protective cover after installation.

[0024] In this invention, the swing connector 5 has a groove 51 at one end, which is hinged to the middle section of the slot 4. The other end of the swing connector 5 is hinged to the middle section of the protective cover 12. The hinge between the swing connector and the middle section of the slot is open, and the groove allows the swing connector to slide a certain distance at the hinge point of the slot, facilitating smooth opening and closing of the protective cover. The other end of the swing connector is hinged to the middle section of the protective cover, which is located at the center of the obtuse angle of the protective cover, allowing the protective cover to fit perfectly over the trapezoidal obtuse angle of the cover mounting portion.

[0025] The hollow fastener 6 described in this utility model is hollow and protruding, and the protruding part is arc-shaped. The hollow protrusion is designed to be able to be inserted into the mounting groove, and the hollow part can cooperate with the damping protrusion for sliding into it.

[0026] The mounting and mating part 7 of this utility model includes a total of four mounting grooves 71 respectively disposed on the upper and lower sections of the left and right sides of the cover mating part. Damping protrusions 72 are provided on the left and right walls of each mounting groove. The damping protrusions 72 can be engaged into the hollow portion of the hollow fastener 6. The mounting grooves allow the hollow fastener of the protective cover to be inserted. When inserted, the damping protrusions slide into the hollow position of the hollow fastener, achieving a damped fastening.

[0027] The protective cover 12 of this invention is provided with reinforcing ribs 8 to increase its strength. The reinforcing ribs enhance the strength of the protective cover, making its protective effect better.
