[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a processing box with a novel protective cover that reduces production costs, improves production efficiency and is easy to assemble.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes a processing box body, on which a photosensitive drum and a protective cover are provided. The protective cover is a long strip component with a U-shaped cross-section and an opening facing downwards. The photosensitive drum is located in the protective cover. The processing box body includes a frame, a first end cover, and a second end cover. The first end cover and the second end cover are respectively provided at both ends of the frame. The photosensitive drum is located between the first end cover and the second end cover. A first mounting hole is opened on the first end cover, and a second mounting hole is opened on the second end cover. A limiting block is provided at one end of the long strip component and inserted into the first mounting hole, and an elastic locking block is provided at the other end and engaged in the second mounting hole.

[0005] Furthermore, a pressure plate is provided at the other end of the elongated component. The pressure plate is located above the elastic locking block and abuts against the upper surface of the second end cap when the elongated component is installed in place.

[0006] Furthermore, an indicator section is provided on the pressure plate.

[0007] Furthermore, one side of the elongated member has an extension portion extending downwards.

[0008] Furthermore, a developing roller is provided on the frame, the developing roller abuts against the photosensitive drum, a first gear is connected to the developing roller, and a second gear and a coupling are connected to the photosensitive drum, the second gear meshing with the first gear.

[0009] Furthermore, the frame is also equipped with a stirring rack, and a third gear is connected to the stirring rack. An intermediate gear is connected between the third gear and the first gear for transmission.

[0010] The beneficial effects of this utility model are:

[0011] In contrast to the shortcomings of existing technologies, this invention addresses the shortcomings of existing technologies by designing the protective cover as a long strip component with a U-shaped cross-section and a downward-facing opening. This allows the protective cover to effectively cover the outside of the photosensitive drum, providing better protection. Furthermore, the integrated structure of this protective cover saves production costs and simplifies assembly while increasing production efficiency. During installation, the protective cover is secured by inserting a limiting block at one end of the long strip component into the first mounting hole, and then engaging the elastic locking block at the other end of the long strip component into the second mounting hole. The elastic locking block's inherent elasticity facilitates the assembly of the long strip component between the first and second end caps. Therefore, this invention offers advantages such as reduced production costs, increased production efficiency, and ease of assembly. Attached Figure Description

[0026] like Figures 2 to 5As shown, in this embodiment, the present invention includes a processing box body 1, on which a photosensitive drum 2 and a protective cover 3 are provided. The protective cover 3 is a long strip component 5 with a U-shaped cross-section and an opening facing downwards. The photosensitive drum 2 is located in the protective cover 3. The processing box body 1 includes a frame 6, a first end cap 7 and a second end cap 8. The first end cap 7 and the second end cap 8 are respectively provided at both ends of the frame 6. The photosensitive drum 2 is located between the first end cap 7 and the second end cap 8. The first end cap 7 has a first mounting hole 9, and the second end cap 8 has a second mounting hole 10. One end of the long strip component 5 is provided with a limiting block 11 that is inserted into the first mounting hole 9, and the other end is provided with an elastic locking block 12 that is engaged in the second mounting hole 10.

[0027] In contrast to the shortcomings of existing technologies, this invention addresses the shortcomings of existing technologies by designing the protective cover 3 as a long strip component 5 with a U-shaped cross-section and a downward-facing opening. This allows the protective cover 3 to effectively cover the outside of the photosensitive drum 2, providing better protection. Furthermore, the integrated structure of this protective cover 3 saves production costs and simplifies assembly while increasing production efficiency. During installation, the protective cover 3 is secured by inserting the limiting block 11 at one end of the long strip component 5 into the first mounting hole 9, and then engaging the elastic locking block 12 at the other end of the long strip component 5 into the second mounting hole 10. The elastic locking block 12's elasticity facilitates the assembly of the long strip component 5 between the first end cap 7 and the second end cap 8. This invention offers advantages such as reduced production costs, increased production efficiency, and ease of assembly.

[0028] like Figure 2 and Figure 3 As shown, in some embodiments, a pressure plate 13 is provided at the other end of the elongated member 5. The pressure plate 13 is located above the elastic locking block 12, and the pressure plate 13 abuts against the upper surface of the second end cover 8 when the elongated member 5 is installed in place. An indicator portion 15 is provided on the pressure plate 13. Specifically, after the elongated member 5 is installed, it is determined whether it is installed in place by observing whether the pressure plate 13 abuts against the upper surface of the second end cover 8. In addition, the arrow markings on the indicator portion 15 indicate the installation direction. Moreover, the setting of the pressure plate 13 and the indicator portion 15 can play a foolproof role. When the installation direction of the elongated member 5 is incorrect, the first end cover 7 will block the pressure plate 13 and the indicator portion 15, thereby avoiding reverse installation.

[0029] like Figure 3 and Figure 4As shown, in some embodiments, one side of the elongated member 5 has an extension portion 16 extending downward. Specifically, by having an extension portion 16 extending downward on one side of the elongated member 5, one side of the elongated member 5 is longer than the other side, thereby increasing the coverage of the protective cover 3 over the photosensitive drum 2 and enhancing the protective effect of the protective cover 3.

[0030] like Figure 6 As shown, in some embodiments, a developing roller 17 is provided on the frame 6, which abuts against the photosensitive drum 2. A first gear 18 is connected to the developing roller 17, and a second gear 19 and a coupling 14 are connected to the photosensitive drum 2. The second gear 19 meshes with the first gear 18. A stirring frame is also provided on the frame 6, and a third gear 20 is connected to the stirring frame. An intermediate gear 21 is drivingly connected between the third gear 20 and the first gear 18. Specifically, the photosensitive drum 2 is driven to rotate by connecting to the coupling 14 through an external device. Furthermore, the meshing of the first gear 18 and the second gear 19, and the meshing of the third gear 20 and the first gear 18 with the intermediate gear 21, enable the processing box to achieve transmission through a single drive. This single drive method has a simple structure, is easy to install, and improves adaptability.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
