Embodiment
Fig. 3 has shown the handle box of the utility model embodiment, and wherein, drum box 300 and Delevoping cartridge 400 can relatively rotate a low-angle around its common axis of rotation X-X, is provided with stressed member 10 in the position of Delevoping cartridge 400 close ends.
Fig. 4 has shown the exploded view of each parts of end of stressed member 10 place Delevoping cartridges, wherein, is provided with powder storehouse 410 in the Delevoping cartridge, is provided with waste powder hopper 310 in the drum box.Stressed member 10 1 sides link to each other with torsion spring 40, and opposite side contacts with limited bolt 20, and the opposite side of limited bolt 20 is connected with spring 30.
As Fig. 8 and shown in Figure 9, limited bolt 20 1 sides have one or more position limit arms 21, and its center has through hole 24, and opposite side has the groove 22 that is used to connect spring 30.
As shown in Figure 4, when above-mentioned these parts assembled, spring 30 was compressed between developing chamber 410 and the limited bolt 20, and limited bolt 20 can move on the direction that is parallel to turning axle x-x under the effect of spring 30 restoring forces.One end of torsion spring 40 is fixed on the location-plate 50, and its elastic tip is stuck in a side of stressed member 10.Location-plate 50 is fixed on an end in powder storehouse 410.
Stressed member 10 has as Fig. 5, Fig. 6 and structure shown in Figure 7, and the one side has the groove (not shown), is used to settle the elastic tip of torsion spring 40.Stressed member 10 also has an extension 11 and axial region 12, and a side of axial region 12 has boss 13, and the quantity of boss 13 can be 2 (as shown in Figure 7), also can be one or more, and its quantity should be corresponding with the quantity of the position limit arm 21 of limited bolt 20.Axial region 12 centers have a through hole 15 coaxial with the through hole 22 of limited bolt 20.One turning axle (not shown) is passed through hole 15 and through hole 22 simultaneously, stressed member 10 can be rotated around this turning axle, and limited bolt 20 can move axially along this turning axle.The free end of position limit arm 21 contacts with the inclined-plane 14 of boss 13.
Handle box is packed into or when taking out printer, the motion process of stressed member 10 such as Figure 10, Figure 11 and shown in Figure 12.Y represents the pack direction of handle box to printer among Figure 10-12, and-y represents the removing direction of handle box from printer.Be in after handle box is not packed the printer or the printer of packing into into when treating print state, stressed member 10 is in initial position shown in Figure 10 under the effect of torsion spring 40, promptly perpendicular to packing into/position of removing direction.
In the printer process of packing into, handle box moves towards the y direction, the extension 11 of stressed member 10 be subjected to printer installing port top (first force section) directed force F 3 promotion and to the rotation of-y direction, as shown in figure 11, the rotation of extension 11 drives boss 13 rotations, causes inclined-plane 14 to promote position limit arm 21 limited bolt 20 is moved to the direction of compression spring 30.At this moment, because the resilient force of spring 30, limited bolt 20 has applied one for stressed member 10 to stop it to-directed force F 2 that the y direction rotates, but, because printer installing port top gives directed force F 3 that extension 11 applies greater than F2, make stressed member 10 rotations so F3 overcomes the prevention power of limited bolt 20, thereby make handle box enter into printer.
When handle box enters into printer, printer installing port top disappears for the directed force F 3 of extension 11, and under the synergy of torsion spring 40 and limited bolt 20, stressed member 10 is got back to initial position (as shown in figure 10).At this moment, photosensitive drums and developer roll are connected at handle box under the effect of spring and are in contact with one another, and enter print state.
When needs cleaning photosensitive drums, the second enforcement portion (not shown) of printer applies a directed force F 4 on the direction of-y extension 11, because F4 connects the directed force F 1 of spring greater than handle box, and stop the directed force F 2 of stressed members 10 rotations less than limited bolt 20, therefore, stressed member 10 remains on initial position under the effect of limited bolt 20, in this state, stressed member 10 keeps relative fixed with Delevoping cartridge 400, therefore, stressed member 10 can drive Delevoping cartridge 400 and rotate, and photosensitive drums is separated with developer roll, thereby enter clean conditions.
In a further embodiment, spring 30 neither be necessary.The position limit arm 21 of limited bolt 20 can have elasticity, its free end contacts with inclined-plane 14, when stressed member 10 drives inclined-plane 14 rotations, inclined-plane 14 promotes the free end of position limit arm 21, makes it that elastic deformation take place, at this moment, the inclined-plane 14 of giving of position limit arm 21 applies a directed force F 2, need only directed force F 2 less than directed force F 3, and, equally also can realize packing into and photosensitive drums and developer roll detachment process of above-mentioned handle box greater than directed force F 4.At this moment, limited bolt can be not and the coaxial setting of stressed member, do not need to connect the groove of spring yet, and only be the fixedly thrust of other end contact stressed member boss of an end.
When handle box took out printer, handle box moved to-y direction, and stressed member 10 rotates to the y direction under the effect of printer installing port top directed force F 3.Because boss 13 was gone up in the opposite direction and rotated this moment, position limit arm 21 can't accept the expulsive force on inclined-plane 14, stressed member 10 is not applied spacing acting force, and F3 is far longer than the elastic force of torsion spring, therefore, stressed member 10 is easy to rotate to the y direction, thereby handle box takes out printer.
In a further embodiment, limited bolt 20 and spring 30 neither be necessary, if torsion spring 40 has enough elasticity, its acting force to stressed member 10 can satisfy greater than directed force F 2 less than directed force F 3, it just can realize the limit function to stressed member 10 separately, thereby realizes above-mentioned each process.
In addition, boss 13 also can not have the inclined-plane, and the free end of position limit arm is made into inclined-plane or slick and sly shape.
In a word, technical conceive of the present utility model is not limited in the foregoing description, can also obtain many different concrete schemes according to design of the present utility model.Any change, combination and the equivalent transformation that carry out according to design of the present utility model all should be included within the described scope of claim.
