Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As it can be seen, the drive assembly of photosensitive drum 1 that this utility model provides, including photosensitive drums 2, driving head 3, compel pushing mechanism 4, flange 5 and limiting component 6.
Driving head 3 engages with flange 5, and flange 5 is arranged on one of them end of photosensitive drums 2.Driving head 3 accepts driving force from imaging device, and transmits power to photosensitive drums 2 by flange 5, drives photosensitive drums 2 to rotate around photosensitive drum shaft.
Compel pushing mechanism 4 for driving head 3 being compeled to be pushed into the position that at least two is different, wherein, during primary importance: driving head 3 substantially overlaps with photosensitive drum shaft；During the second position, driving head 3 is positioned at the position substantially parallel with photosensitive drum shaft.
Specifically, as shown in Figures 2 to 11.Compel pushing mechanism 4 to include compeling pushing block 40, support member 42 and flexible member 41.Driving head 3 includes Part I 30 and Part II 33, and Part I 30 is provided with through hole 31, arranges pin 32 in through-holes, and Part II 33 connects Part I, and Part II has at least two projection along driving head is axially arranged.Projection is for receiving the driving force of imaging device.Compel pushing block 40 to be flexibly connected with driving head 3.
Limiting component 6, for axial support lugn 5, is provided with opening 60, and driving head 3 is connected with flange 5 by opening 60.Supporting surface 60 it is additionally provided with on limiting component 6, supporting surface 60 is arranged along open annular, can be continuously or intermittently, at least include upper part and lower part, for coordinating restriction handle box position in an imaging device with imaging device when installing handle box to forming apparatus.Being additionally provided with guide rail 62 on limiting component 6, compel pushing block 40 and be arranged on guide rail 62, it can slide around guide rail 62, and one end of transition 62 is additionally provided with screwed hole 63, is used for installing screw and prevents urgent pushing block 40 from coming off from transition 62.
Support member 42 includes circular hole 420 and boss 422, and circular hole 420 diameter passes circular hole 420 more than the maximum gauge of driving head 3 Part I, driving head 3 Part I.Boss 422 is used for supporting flexible member 41.Flexible member 41 one end abuts with limiting component 6, the other end abuts with boss,
Flange 5 includes caving in 51 and the locating part 52 that is arranged in depression 51.The end of driving head 3 Part I abuts with depression 51, and pin 32 can engage with locating part 52, drives photosensitive drums to rotate with transmission from the driving force that imaging device accepts.
In this utility model embodiment, it is to be realized by the engagement of pin and 2 locating parts that driving head transmits power to flange.Can also is that alternatively and arrange just like the projection shown in Part II on driving head Part I, the cooperation being provided with arc-shaped concave at flange realizes.As long as engaging between driving head with flange there are enough magnitudes of interference, all can realize.Specifically driving head first move a certain amount of after the most just drive flange to rotate, during dismounting, also allow for driving head driving force transmission position and accept position with flange driving force and first separate, this is no longer going to repeat them.
Being illustrated in figure 8 the partial structurtes schematic diagram of imaging device, as shown in Figure 8, imaging device 100 includes the attachment rail 101 of side, imaging device driving head 102 and projection 103.The schematic diagram mounted and dismounted for the drive assembly of photosensitive drum provided with this utility model and handle box as shown in Figures 9 to 11.
As shown in the figure, when handle box is installed to imaging device 100, installation direction is X-direction, compel pushing block 40 first to contact with projection 103, user is to one thrust F forward of handle box ', projection is given and is compeled one counteracting force F of pushing block accordingly, compel pushing block 40 and power F is transferred to driving head 3, two component F1 and F2 will be produced in the position that urgent pushing block 40 contacts with driving head 3, wherein F1 is for rotating to an angle driving head 3, and driving force F2 is for overcoming flexible member 41 to the elastic force of driving head.Namely under the effect of power F, driving head 3 will rotate to an angle and return to the position the most coaxial with photosensitive drum shaft around the axial O of driving head.Then, imaging device driving head 102 engages with projection 33, and under the effect of imaging device driving head 102, driving head 3 therefrom accepts driving force and is transferred to flange 5 thus drives photosensitive drums 2 to rotate together.
When demounting process cartridge, user pulls outward handle box, compel pushing block 40 to separate with projection 103, under the effect of flexible member 41, driving head 3 moves toward the direction of deviation photosensitive drum shaft, and occur to rotate around the axial O of driving head 3 under the effect of elastic force, thus, projection 33 separates with imaging device driving head 102, and handle box takes out from imaging device.
Installed above and dismounting during, the state between power transfering part and the power receiving portion of flange of driving head separate with contact between switching.
The drive assembly of photosensitive drum of this utility model offer and handle box, solve the problem driving assembly to come off the most in transit in prior art.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model each embodiment technical scheme.
