Description

[Technical field]

[0001] The utility model relates to the technical field of printing consumables equipment, in particular to a structure for a side cover baffle of a toner cartridge. [Background technology]

[0002] In office equipment such as printers and copiers, toner cartridges, as core consumable components, undertake the important task of transferring images or text from electronic devices to paper media. In the existing assembly structure of toner cartridges, firstly, the powder bin shell usually has a lug connection structure connected to the waste powder bin shell, and this lug connection structure is mostly a molded plate with a long protruding length, and the plate surface is protruded with an integrally formed convex edge. In order not to interfere with the rotation of the photosensitive drum after assembly, the convex edge is generally arc-shaped and is located on the side of the end of the photosensitive drum after assembly. This structure will cause the lug connection structure to have more stress concentration points, resulting in poor strength and easy to break during transportation; secondly, the side cover baffle used to be installed on the side of the powder bin and the waste powder bin during the assembly of the toner cartridge is generally a relatively flat plate, which is also easy to bend and deform during transportation. Therefore, a structure for the side cover baffle of the toner cartridge is needed, which can not only reduce the stress concentration points of the lug connection structure between the powder bin and the waste powder bin, but also increase the bending strength of the side cover baffle, so that both are not easy to break and are easy to transport.

The structure of the toner cartridge side cover baffle of the present embodiment is provided with a reinforcing mechanism 2 on the baffle assembly 1, and adopts a first flange 21 provided on the first side cover 11 and a second flange 22 provided on the second side cover 12 to replace the flanges on the lug connection structure between the powder bin and the waste powder bin in the existing toner cartridge structure, so that the powder bin shell structure corresponding to the baffle assembly can effectively reduce the plate area of ​​its lug connection structure in design, so as to reduce the stress concentration point of the lug connection structure between the powder bin and the waste powder bin, and facilitate the transportation of the powder bin shell parts; at the same time, the first flange 21 and the second flange 22 are arranged in a curved arc shape, which not only make way for the installation of the photosensitive drum, but also serve as reinforcing ribs for the first side cover 11 and the second side cover 12 respectively, so that each side cover baffle is not easy to bend, and the transportation of the side cover baffle parts is convenient.

[0024] Further, the first flange 21 is convexly arranged on the edge of the first side cover 11 close to the first penetration port 111, and the second flange 22 is convexly arranged on the edge of the second side cover 12 close to the second penetration port 121.
