Detailed Description
Referring to fig. 3, an embodiment of the present invention provides a process cartridge for an image forming apparatus, which can be detachably mounted in a cavity of the image forming apparatus, the cavity includes an inner wall and a cover plate, the cover plate is used for covering the process cartridge, the process cartridge includes a housing 301, at least one abutting member 302 is convexly disposed on an outer surface of the housing 301, and the abutting member 302 is used for abutting against the inner wall of the cavity and/or the cover plate, so as to position the process cartridge in the cavity.
In this embodiment, since the abutting member 302 is convexly disposed on the outer surface of the casing 301, and when the processing cartridge is installed in the cavity of the image forming apparatus, the abutting member 302 can abut against the inner wall and/or the cover plate of the cavity of the image forming apparatus to position the processing cartridge in the cavity, the positioning of the processing cartridge in the cavity can be realized by the abutting member 302 without arranging a positioning column on the casing 301 to match with the guide rails disposed on the two sides of the cavity, and even if the positions and sizes of the guide rails of the image forming apparatus are different, the use of the processing cartridge provided by the present invention is not affected.
In this embodiment, two sides of the housing 301 may be formed as a plane or a groove, or may be formed as a protrusion that does not touch the inner wall of the cavity or extend into the guide rail of the image forming apparatus, so as to ensure the versatility of the process cartridge.
In this embodiment, the abutting member 302 is preferably used for abutting against the cover plate. Because the cover plate covers the processing box after the processing box is placed in the cavity, a certain space variable exists between the cover plate and the processing box, even if the distance between the cover plate and the processing box is slightly increased due to the fact that the abutting piece 302 abuts against the cover plate, normal use of equipment cannot be influenced, the abutting piece 302 is used for abutting against the cover plate to enable the processing box to be positioned in the cavity, requirements for the size and the deformation performance of the abutting piece 302 in the positioning process can be reduced, and the universality of the processing box is further improved.
Referring to fig. 4, in the present embodiment, preferably, the supporting member 302 includes a bottom plate 303, a first end of the bottom plate 303 is provided with a protrusion 304, the protrusion 304 protrudes from an upper surface of the bottom plate 303, the protrusion 304 is used for supporting the inner wall of the cavity and/or the cover plate, a second end of the bottom plate 303 is provided with a connecting member 305, the connecting member 305 protrudes from a lower surface of the bottom plate 303, and the connecting member 305 is connected to the housing 301. Thus, the holding member 302 is formed in a zigzag shape, and the deformation performance of the holding member 302 can be improved, thereby further improving the versatility of the process cartridge.
Referring to fig. 4 and 5, in the embodiment, preferably, the connecting member 305 is a first retaining member, and the outer surface of the housing 301 is provided with a first groove 306, and the first retaining member is configured to be retained in the first groove 306 so as to connect the abutting member 302 with the housing 301. Therefore, the abutting piece 302 and the shell 301 are connected in a clamping manner, so that the disassembly is convenient, meanwhile, the deformation performance of the abutting piece 302 can be improved by the connecting mode of clamping connection, in addition, the first grooves 306 can be arranged at a plurality of positions on the outer surface of the shell 301, so that the abutting piece 302 can be arranged at a plurality of positions on the outer surface, and the image forming device can be used in image forming devices of different models more easily. Of course, the connecting member 305 may be connected to the housing 301 by welding or bolting.
In this embodiment, preferably, the holding member 302 further includes a second retaining member 307, and the second retaining member 307 is connected to the first retaining member through a connecting plate 308; the outer surface of the housing 301 is further provided with a second groove 309, and the second retaining member 307 is used for retaining in the second groove 309. Thereby, the stability of the connection between the holding member 302 and the housing 301 can be further increased.
In this embodiment, it is preferable that the cross sections of the first retaining member and the second retaining member 307 are both U-shaped, the second end of the bottom plate 303 is connected to one side of the open end of the first retaining member, the first end of the connecting plate 308 is connected to the other side of the open end of the first retaining member, and the second end of the connecting plate 308 is connected to one side of the open end of the second retaining member 307. Since the cross sections of the first and second retaining members 307 are U-shaped, the first and second retaining members 307 have a certain amount of deformation, and can be better engaged with the first and second grooves 306 and 309.
In this embodiment, the supporting member 302 is preferably an integrally formed supporting member 302. Therefore, the toughness of the holding piece 302 is better, the deformation performance of the holding piece 302 is improved, and the universality of the processing box is further improved.
In this embodiment, the supporting member 302 may be made of one or more materials such as polyoxymethylene, polypropylene, acrylonitrile butadiene styrene copolymer, etc. to ensure the deformation performance of the supporting member 302, but the supporting member 302 may also be made of other plastic materials, rubber materials or metal materials.
In this embodiment, preferably, the protrusion 304 includes a top surface 312 and a first side surface 313, the first side surface 313 is connected to the top surface 312 and faces away from the second end of the bottom plate 303, and the top surface 312 and/or the first side surface 313 are used for abutting against the inner wall of the cavity and/or the cover plate. Since the top surface 312 and the first side surface 313 of the protrusion 304 can both abut against the inner wall of the cavity and/or the cover plate, the process cartridge can be positioned in the cavity of image forming apparatuses of more models, and the versatility of the process cartridge is further improved. Because the first side surface 313 faces away from the second end of the bottom plate 303, when the first side surface 313 abuts against the inner wall of the cavity and/or the cover plate, the protruding portion 304 and the bottom plate 303 can both deform, thereby facilitating the abutting member 302 to exert better deformation performance in the abutting process.
Referring to fig. 6, in the present embodiment, preferably, the protruding portion 304 is detachably connected to an elastic element 310, and the elastic element 310 is used for abutting against the inner wall of the cavity and/or the cover plate. Because the elastic element 310 has better self-deformation performance, the abutting piece 302 can better abut against the inner wall of the wall body or the cover plate, and the universality of the processing box can be further improved. The elastic element 310 may be a sponge pad, a rubber member, or a spring.
In this embodiment, it is preferable that the holding member 302 is plural, whereby the stability of positioning of the process cartridge in the cavity of the image forming apparatus can be improved.
In this embodiment, preferably, the outer surface of the housing 301 is further provided with a flexible positioning column 311, which is slidably disposed in the guide rails disposed on the two sides of the cavity. The flexible positioning columns 311 are slidably arranged in the guide rails arranged on the two sides of the cavity, so that the positioning stability of the processing box in the cavity of the image forming device can be improved. The flexible positioning column 311 can be made of a flexible metal material, and a user can change the shape of the flexible positioning column 311 according to the position and size of the guide rail, so that the flexible positioning column 311 can be matched with the guide rail. Of course, the flexible positioning column 311 may also be a rubber or spring member as long as it has a deformation property.
