处理盒

Abstract

本实用新型公开了一种处理盒，可拆卸地安装到图像形成设备主体中的容置腔内；所述容置腔设有定位部和限制部，所述处理盒还包括：鼓单元，包括鼓框架和感光鼓；所述感光鼓沿所述鼓框架的纵向方向设置并被设置为能够围绕旋转轴旋转；显影单元，包括显影框架和可旋转地被所述显影框架支撑的显影辊，所述显影辊可供应显影剂至所述感光鼓；和筋板，设置在所述处理盒上并朝向所述图像形成设备主体，所述筋板设置为从所述处理盒的上表面突出；本实用新型的处理盒不对定位部和限制部形成导槽式限位，减少处理盒在安装过程中与图像形成设备主体上的筋条产生干涉或碰撞，具有结构简单和装机顺畅的优点。

Claims

1. A process cartridge detachably mountable to a housing cavity in an image forming apparatus main body; said housing cavity provided with a positioning portion and a restricting portion, said restricting portion at least partially overlapping said positioning portion as viewed in a mounting direction of said process cartridge; characterized in that, The processing box also includes: A drum unit includes a drum frame and a photosensitive drum; the photosensitive drum is arranged along the longitudinal direction of the drum frame and is configured to rotate about a rotation axis; The developing unit includes a developing frame and a developing roller rotatably supported by the developing frame, the developing roller supplying developer to the photosensitive drum; A rib is disposed on the processing box and facing the image forming device body. The rib is configured to protrude from the upper surface of the processing box. There are multiple ribs, which are spaced apart, or one rib is disposed and extends along the installation direction. During the installation of the processing box, the rib is configured to contact the limiting part and / or the positioning part to guide and limit the installation of the processing box.

2. The process cartridge according to claim 1, wherein, The number of stiffeners is two, and in the installation direction, the two stiffeners are spaced apart and respectively correspond to the positioning part and the limiting part.

3. The process cartridge of claim 2 wherein, The stiffening plates are staggered relative to each other in the installation direction.

4. The process cartridge according to any one of claims 1-3, wherein, The longitudinal direction is perpendicular to the installation direction, and the projections of the stiffeners do not overlap in the longitudinal direction.

5. The process cartridge according to claim 4, wherein, In the longitudinal direction, the side from which the processing box receives the driving force from the main body of the image forming device is the driving side; the rib is disposed on the driving side, and the rib includes a first rib and a second rib.

6. The process cartridge of claim 5 wherein, In the longitudinal direction, the first rib is located on the side further away from the driving side, and the second rib is located on the other side closer to the driving side; or the first rib is located on the side closer to the driving side, and the second rib is located on the other side further away from the driving side.

7. The process cartridge of claim 5 wherein, In the longitudinal direction, both the first stiffener and the second stiffener are located on the side closer to / away from the driving side.

8. The process cartridge of claim 1, wherein, In the longitudinal direction, the side of the stiffener contacts the limiting part and / or the positioning part.

9. The process cartridge of claim 1, wherein, The number of stiffening plates is one, and the stiffening plate includes multiple sub-stiffening plates spaced apart from each other, and the multiple sub-stiffening plates together form the stiffening plate.

10. The processing box according to any one of claims 1-3, 8 and 9, characterized in that, The image forming device body is provided with a box pressing member; when the processing box is installed in place, the box pressing member limits the processing box, so that the processing box is kept in the correct installation position.
