Problems solved by technology

When the drive head receives the drive force from the drive head of the imaging device and rotates, the force is transmitted to the bracket body through the drive contact and the pivot, and the drive force transmission is unstable
In addition, due to the space limitation at the notch, the pivot is usually thin. When the drive head receives the driving force from the imaging device and rotates, the torque generated by the rotation is very easy to damage the pivot.
Limited by the gap space, it is not convenient to install the driving contact and the rebound reset piece

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] Such as figure 1 As shown, the developing cartridge 100 includes a cartridge body 101, and the driving assembly 10 is arranged at one end of the developing cartridge 100 in the longitudinal direction, so as to engage with the driving shaft 200 of the electrophotographic imaging device to transmit the driving force to the processing members in the developing cartridge 100, and the driving shaft The end of 200 has a radial protrusion 201 . There may be components such as a photosensitive drum, a developing roller, and a powder feeding roller in the developing cartridge. The driving assembly may be arranged at the end of the photosensitive drum or developing roller and be coaxial with it, so as to receive the driving force and directly drive the photosensitive drum or developing roller to rotate. Because it is not coaxial with any component, but it...

Abstract

The invention provides a driving assembly and a developing box. The driving assembly provided by the invention comprises a cylinder part and a connection part which are coaxially arranged, wherein an acting force device is arranged on each of the cylinder part and the connection part, the connection part comprises a sleeve and a guide rod which are coaxially arranged, a connection claw is arranged at an end part of the guide post, the maximum deflection angle of the connection claw, limited by the sleeve, relative to the axis of the guide post becomes large with the outward axial movement of the guide post, and the distance of the connection claw outwards protruding along the axial direction of the guide post becomes small. The driving assembly has the advantages of structural stability, and is simple and convenient to operate, the developing box is convenient to install and disassemble, and stable transfer of a driving force can be achieved.

Description

technical field [0001] The invention relates to the field of electrophotographic imaging, in particular to a driving assembly for transmitting driving force in an electrophotographic imaging device and a developing box with the driving assembly. Background technique [0002] The imaging principle of electrophotographic imaging equipment is that firstly, the photosensitive drum or photosensitive belt coated with photosensitive material is uniformly charged, and then the surface is exposed with a laser beam, the charge of the irradiated part disappears, and the unirradiated part still carries the charge to form Electrostatic latent image, and then using a developing roller and other components to provide a developer such as toner to the electrostatic latent image for development, and then transfer to the printing medium, and fix it by heating to form a stable image on the printing medium image. [0003] Generally, a developing cartridge is detachably installed in an electroph...
