Problems solved by technology

[0006] However, the size of the driving force receiver of the existing driving force transmission assembly is very small, and a gap 14 is formed at the bottom of the guide groove 11, for example, a gap 14 is formed between the driving gear 16 and the protrusion 17 of the electronic imaging device 10
Due to the relatively small size of the driving force receiving part, it is easy to slide into the gap 14, making it difficult for the driving force receiving part to slide to the position matched with the drive shaft 18, resulting in the inability to install the toner cartridge, affecting the installation and use of the toner cartridge

Abstract

The invention provides a driving force transmission assembly, a rotating member, a toner cartridge and electronic imaging equipment. The driving force transmission assembly comprises a driving force receiving piece and a driving gear. The driving force receiving piece is provided with a rod body and a driving force receiving part located at one end of the rod body, and the rod body is inserted into the driving gear and drives the driving gear to rotate. The rod body is sleeved with a reset piece installed in the driving gear, and the rod body is further provided with a limiting piece. The end face, away from the driving gear, of the driving force receiving part is an outer end face, and driving force receiving teeth extending outwards are arranged on the outer end face. The end face, close to the driving gear, of the driving force receiving part is an inner end face, the diameter of the inner end face is larger than that of the outer end face, a guiding face is formed between the inner end face and the outer end face, and the diameter of the inner end face is larger than the gap size of the bottom of a guiding groove of the electronic imaging equipment. The rotating member comprises a barrel and the driving force transmission assembly. The toner cartridge is provided with the rotating member. According to the invention, smooth mounting of the toner cartridge can be ensured.

Description

technical field [0001] The present invention relates to the technical field of printing consumables used in laser printers, in particular to a driving force transmission assembly, a rotating member having the driving force transmission assembly and a toner cartridge, and an electronic imaging device having the above toner cartridge. Background technique [0002] In electronic imaging equipment, such as electrostatic copiers or digital copiers and all-in-one printers, a toner cartridge loaded with toner is provided. Usually, the toner cartridge includes a toner bin containing toner, and a photosensitive drum is arranged on one side of the toner bin , developing roller and other rotating parts. Usually, the photosensitive drum, developing roller and other rotating parts are rotatably supported between the two end walls of the box body of the toner cartridge, and the rotating parts include a cylinder body and a driving force transmission assembly installed at the axial end of t...
