To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
As illustrated, the drive assembly of photosensitive drum 1 that the present invention is provided, including photosensitive drums 2, driving head 3, compel pushing mechanism 4, flange 5 and limiting component 6.
Driving head 3 is engaged with flange 5, and flange 5 is arranged on one of end of photosensitive drums 2.Driving head 3 receives driving force from imaging device, and transmits power to photosensitive drums 2 by flange 5, drives photosensitive drums 2 to be rotated around photosensitive drum shaft.
Compeling pushing mechanism 4 is used to compel driving head 3 to be pushed at least two different positions, wherein, during first position：Driving head 3 is substantially overlapped with photosensitive drum shaft；During the second place, driving head 3 is located at the position substantially parallel with photosensitive drum shaft.
Specifically, as shown in Figures 2 to 11.Compeling pushing mechanism 4 includes compeling pushing block 40, support member 42 and flexible member 41.Driving head 3 includes being provided with through hole 31 on Part I 30 and Part II 33, Part I 30, sets pin 32 in through-holes, and the connection Part I of Part II 33, Part II has at least two projections along driving head is axially arranged.Projection is used for the driving force for receiving imaging device.Compel pushing block 40 to be flexibly connected with driving head 3.
Limiting component 6 is used for axial support lugn 5, is provided with opening 60, driving head 3 is connected by opening 60 with flange 5.Supporting surface 60 is additionally provided with limiting component 6, supporting surface 60 is set along open annular, can be continuously or intermittently, at least including upper part and lower part, for coordinating the position of limitation handle box in an imaging device with imaging device when handle box is attached into forming apparatus.Guide rail 62 is additionally provided with limiting component 6, compels pushing block 40 and is arranged on guide rail 62, it can be slided around guide rail 62, one end of transition 62 is additionally provided with screwed hole 63, prevents that compel pushing block 40 comes off from transition 62 for installing screw.
Support member 42 include circular hole 420 and boss 422, circular hole 420 with diameter greater than the Part I of driving head 3 maximum gauge, the Part I of driving head 3 pass through circular hole 420.Boss 422 is used to support flexible member 41.The one end of flexible member 41 is abutted with limiting component 6, the other end abuts with boss,
Flange 5 includes depression 51 and the locating part 52 being arranged in depression 51.The end of the Part I of driving head 3 is abutted with depression 51, and pin 32 can be engaged with locating part 52, drives photosensitive drums to rotate to transmit the driving force received from imaging device.
In the embodiment of the present invention, driving head, which transmits power to flange, to be realized by engaging for pin and 2 locating parts.The projection set on driving head Part I just like shown in Part II is alternatively can also be, is provided with the cooperation of arc-shaped concave to realize in flange.As long as engaging between driving head and flange there are enough magnitudes of interference, it can realize.Specifically driving head first move it is a certain amount of after just drive flange to rotate, during dismounting, also allow for driving head driving force transmission position and receive position with flange driving force and first separate, this is no longer going to repeat them.
The partial structural diagram of imaging device is illustrated in figure 8, as shown in figure 8, imaging device 100 includes the attachment rail 101 of side, imaging device driving head 102 and projection 103.It is as shown in Figures 9 to 11 the schematic diagram of drive assembly of photosensitive drum and the handle box installation and removal provided with the present invention.
As shown in the figure, when handle box is attached into imaging device 100, installation direction is X-direction, compel pushing block 40 to contact with projection 103 first, user gives handle box one thrust F ' forward, accordingly projection, which is given, compels one reaction force F of pushing block, compel pushing block 40 and power F is transferred to driving head 3, the position contacted in urgent pushing block 40 with driving head 3 will produce two component F1 and F2, wherein F1 is used to rotate to an angle driving head 3, and driving force F2 is used for the elastic force for overcoming flexible member 41 to driving head.Namely in the presence of power F, driving head 3 will rotate to an angle around driving head axial direction O and return to position substantially coaxial with photosensitive drum shaft.Then, imaging device driving head 102 is engaged with projection 33, in the presence of imaging device driving head 102, and driving head 3 therefrom receives driving force and is transferred to flange 5 to drive photosensitive drums 2 to rotate together.
In demounting process cartridge, user pulls outward handle box, compel pushing block 40 to separate with projection 103, driving head 3 is moved toward the direction for deviateing photosensitive drum shaft in the presence of flexible member 41, and occur to rotate around the axial direction of driving head 3 O in the presence of elastic force, thus, projection 33 is separated with imaging device driving head 102, and handle box takes out from imaging device.
During installed above and dismounting, the state between the power transfering part of driving head and the power receiving portion of flange switches between separation and contact.
Drive assembly of photosensitive drum and handle box that the present invention is provided, solve the problem of drive component easily comes off in transit in the prior art.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although the present invention is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It can still modify to the technical scheme described in foregoing embodiments, or carry out equivalent to which part technical characteristic；And these modifications or replacement, the essence of appropriate technical solution is departed from the spirit and scope of various embodiments of the present invention technical scheme.
