Driving head includes the first flexible member 14, shaft portion 16 and the claw 15 being set on shaft portion 16.Claw 15 can be along shaft portion about 16 stretching motion.
Shaft portion 16 includes main body 160, main body 160, and one end of main body 160 is provided with depression 161, and the other end is provided with lug 162, and lug 162 extends along the direction of vertical body 160 axis, and the number of lug 162 is 2, and 2 lugs 162 are connected by contiguous block 164.Being additionally provided with the first hole 163 on shaft portion 16, shaft portion 16 is formed in one.
Claw 15 includes supporting part 150, connecting portion 151 and lobe 152, lobe 152, and the number of lobe 152 is two, and connecting portion 151 connects supporting part 150 and lobe 152.Supporting part 150 and lobe 152 extend along vertical joints 151 axial direction.The one side of supporting part 150 is for being connected with the first flexible member 14, and another side is arc or acclive, is used for compeling pushing device contact.The centre of supporting part 150 and connecting portion 151 is through hole.Connecting portion 151 is additionally provided with depression 155 near the position of lobe 152.Depression 155 is used for accommodating contiguous block 164.Lobe 152 spigot surface 154 and screens 153, screens 153 is in an acute angle with the planar shaped of vertical joints 151 axis.
Driving head also includes that snap ring 13 and pin 17, snap ring 13, for after shaft portion 16 is installed to photosensitive drum gear 12, is set in the first depression 161 and fixes shaft portion 16.Pin 17 is arranged on the first hole 163, for the driving force on shaft portion 16 is transferred to photosensitive drum gear 12.
Urgent pushing device includes compeling pushing block 21 and the second flexible member 22, compels pushing block 21 and includes the first opening 214 and the second opening 215, compels pushing block 21 and includes the first end 212 and the second end 213, and the first end 212 is for accepting the urgent thrust of imaging device, such as the lid of imaging device.Second end 213 contacts with the supporting part 150 of claw 15, is provided with arc guide surface.Second flexible member 22 is arranged between the first opening 214, connects respectively and compels pushing block 21 and protecting cover 3.Under normal condition, under the effect of the second flexible member 22, compel pushing block 21 and move toward the first end 212 direction, after the first end 212 receives the urgent thrust of imaging device lid, overcome the active force of the second flexible member 22, compel the pushing block 21 direction motion toward the second end 213.
Urgent pushing device also includes that lever 23, lever 23 include lever main body 230, the second hole 232 being arranged on lever main body 230, the 3rd end 231 and the 4th end 233 of lever 23.3rd end 231 can accept the lifting force on imaging device track, and the 4th end 233 then can contact with supporting part 150.Second hole 232 and the second opening 215 are arranged on the boss of protecting cover.In terms of an extreme direction of handle box 10, the second hole 232 is comprised by the second opening 215.
Lever 23 is for overcoming the gmatjpdumamics between claw 15 and imaging device driving head.Specifically, when handle box 10 pulled down by imaging device, need up to carry handle box, 3rd end 231 of lever 23 abuts with the track of imaging device and can apply a lifting force to track, and one power of track retroaction will be walked downward to lever, the 3rd end 231 of lever, correspondingly the 4th end 233 will be toward walking, because the 4th end 233 contacts with supporting part 150, supporting part 150 1 can be given toward the active force in photosensitive drum gear 12 direction so that screens 153 separates with imaging device driving head.
Being axis hole 121 in the middle of photosensitive drum gear 12, axis hole 121 is extended with step surface 123 and guide groove 122 toward place.Step surface 123 is for supporting one end of the first flexible member 13, and guide groove 233 is for card pin 17.
Figure 10 is installed to a kind of state diagram of imaging device for the handle box that this utility model provides, Figure 11 is the another kind of state diagram that the handle box that this utility model provides is installed to imaging device, as shown in Figure 10 and Figure 11: A is the state diagram before photosensitive drum driving head contacts with imaging device driving head 30, B is the state diagram that photosensitive drum driving head contacts with imaging device driving head 30, and C is normal operating conditions figure.Handle box 10 is in time being installed to normally use, first user can apply a motive force in X-direction when installation process box 10, after handle box driving head contacts with imaging device driving force, under the effect of this motive force, claw 15 and imaging device driving head 30 can shrink toward contrary direction, the distance that wherein imaging device driving head 30 shrinks is about 2mm, and the distance that claw 15 shrinks is more than 3mm, it is therefore preferable to 4.5mm.nullUnder the effect of motive force and spigot surface 154，It is installed to operating position，Close the lid of lower imaging device immediately，Lid compels, by giving urgent pushing block 21 1, the directed force F 1 that thrust makes urgent pushing block 21 be no longer cancel out the first flexible member 14，Directed force F 1 time at the first flexible member 14，Claw 15 is by toward moving to the direction of imaging device driving head 30，Same imaging device driving head 30 moves toward the direction of claw 15，Imaging device driving head 30 rotates to precalculated position and that is to say that imaging device driving head 30 power transfering part rotates to the position relative with convex surface 162，Imaging device driving head 30 and claw 15 all return to operating position，Imaging device driving head 30 is rotated further，Power transfering part thereon is engaged with screens 153，Thus drive claw 15 to rotate，Claw transmits power to shaft portion 16 by convex surface 162 with coordinating of depression 155，Shaft portion 16 then transfers power to photosensitive drum gear 12.
Figure 13 show the movement state diagram that handle box is pulled down from imaging device, as shown in figure 13, in the directed force F 1 ' of urgent pushing device, under F2 ', screens 153 can with the power part of the force on imaging device driving head 30 from, thus handle box 10 is taken out from imaging device.
The drive assembly of photosensitive drum of the present embodiment and handle box, by telescopically being arranged by the claw of photosensitive drum driving head, solve the problem that drive assembly of photosensitive drum in prior art comes off the most in transit.
Embodiment two
The present embodiment repeats no more with the something in common of embodiment one.As shown in Figure 13 to Figure 16, being with embodiment one difference in this enforcement, the structure of driving head is different.
Specifically, driving head includes claw 15 and shaft portion 16.Lobe 152 number of claw 15 is 2, and 2 lobe 152 are connected by annulus 156, the most extended prominent wall 157 of lobe 152, and prominent wall 157 is for accepting the power of power transfering part on imaging device driving head.
The one end in axle portion 16 is the first depression 161, and the second end is projection 162, and projection 162, for coordinating with the second depression on claw 15, accepts the driving force of claw 15.
Photosensitive drum gear 12 is with embodiment one difference, and the mid portion of embodiment one and gear parts are to be directly connected to by plane, is provided with multiple reinforcement in embodiment two, and really in two embodiments, the structure of photosensitive drum gear 12 can be exchanged.
The drive assembly of photosensitive drum of the present embodiment and handle box, by telescopically being arranged by the claw of photosensitive drum driving head, solve the problem that drive assembly of photosensitive drum in prior art comes off the most in transit.
Preferably, by urgent pushing device is provided with urgent pushing block and lever.It can also is that and is provided only with lever alternatively.
