Problems solved by technology
[0003] Existing toner cartridges generally can only be used with one type of imaging device. The reason is that the structure of the drive head in different types of imaging devices is different, so the existing toner cartridge cannot be used with various imaging devices. It is not conducive to the use of end users, and increases the cost of users, so it is very practical to increase the compatibility of the driving force transmission parts of the toner cartridge for different imaging devices

Embodiment Construction
[0031] refer to figure 1 , figure 1 is a structural diagram of the toner cartridge 1. The toner cartridge 1 includes a frame 11 and a roller rotatably supported in the frame 11. The roller includes at least one of the developing roller 12, the powder feeding roller or the stirring frame. The gear assembly 13 includes a driving force transmission component 2 for receiving external driving force.
[0032] refer to figure 2 with image 3 , figure 2 with image 3 It is a structural diagram of the driving force transmission part 2 under different viewing angles. The driving force transmission member 2 includes a gear seat 21 , which is a rotating body centered around the axis L1 and extends in a cylindrical shape. A gear 22 is arranged on the outer peripheral wall of the first axial end of the gear seat 21 , and the gear 22 extends axially.
[0033] On the second end of the gear seat 21 in the axial direction, a circular groove 23 concave in the axial direction is formed....

The invention provides a driving force transfer part and a toner cartridge. The driving force transfer part comprises a cylindrical extending gear base, wherein the peripheral wall of the gear base is provided with gears along the circumferential direction, and a concave circular groove is formed in the end part of the gear base along the axial direction; two driving force receiving blocks are arranged from the peripheral wall of the circular groove to inside, the two driving force receiving blocks are symmetrically arranged relative to the axis of the gear base, the radial end surfaces of the driving force receiving blocks are successively provided with first driving force receiving parts, arc-shaped limiting parts and second driving force receiving parts; the arc-shaped limiting parts are arranged between first driving parts and second driving parts, the second driving force receiving parts are more close to the axis of the bearing base than the first driving force receiving parts, and a toner cartridge is provided with the driving force transfer part. The different driving heads can be well matched with a driving wheel transfer part by virtue of the driving force transfer part provided by the invention, so that driving force transfer is realized, the driving force transfer part is simple in structure and good in compatibility, and can be conveniently used by end-users.
Description
technical field [0001] The invention relates to the field of printing consumables, in particular to a driving force transmission component and a toner cartridge installed with the driving force transmission component. Background technique [0002] A toner cartridge is generally used in an imaging device as a toner supply source for imaging, and most existing toner cartridges can be detachably installed in the imaging device for use. Usually, the photosensitive drum, the developing roller, the powder feeding roller and the stirring frame all receive the driving force of the imaging device through the gears assembled at the ends to work in rotation. [0003] Existing toner cartridges generally can only be used with one type of imaging device. The reason is that the structure of the drive head in different types of imaging devices is different, so the existing toner cartridge cannot be used with various imaging devices. It is not conducive to the use of end users, and increase...
