Accepting groove 31b is arranged on the below of compression zone 31a in X direction and along the through extensible member 31 of Y-direction, it is configured to hold meshing part 34 to wherein.
First flexible member mounting groove 31c is configured to installation first flexible member 33.
Guide part 31d is the direction protrusion of the external peripheral surface being formed at extensible member 31, and during installation, guide part 31d coordinates with the gathering sill 38d of geared parts 38, in order to the slip of guide extension parts 31.
Deformation component 32 is mounted in the accepting groove 31b of extensible member 31, to have in the normal direction Y-direction of developer roll axial direction X to be outstandingly formed with radial deformations 32a, and radial deformations 32a is stressed, and elastic deformation occurs.
First flexible member 33 is contained in the first flexible member mounting groove 31c, one end abuts extensible member 31, the other end abuts geared parts 38, it provides restoring force F1 (see Fig. 7) to extensible member 31, make it relative to geared parts 38 Telescopic sliding, in the present embodiment, the first flexible member 33 is a Compress Spring, and it can also be set to other flexible members such as elastic caoutchouc.
Meshing part 34 is contained in accepting groove 31b, geared parts 38 is fixed to by bayonet lock 35, meshing part 34 is provided with the meshing part mounting hole 34c coordinated with bayonet lock 35, it can at disengaged orientation, (Fig. 4 a) and between the position of engagement (Fig. 4 b) rotates around meshing part mounting hole 34c, meshing part 34 is set to two and has the joggle post 34a engaged with machine driving head 100 in image processing system, meshing part 34 is also provided with hook part 34b, hook part 34b is set to coordinate with the second flexible member 37, thus make meshing part 34 be in disengaged orientation.
Second flexible member 37 is contained in geared parts 38, its one end connects meshing part 34, the other end connects 38e bottom geared parts, and it applies torsion to meshing part 34 makes meshing part 34 be in disengaged orientation, and in the present embodiment, the second flexible member 37 is a torsion spring.
See Fig. 4, geared parts 38 is arranged on the side of box body 10, geared parts 38 is formed with four erection column 38b to be connected by erection column hole clipping 38a extensible member 31, geared parts 38 excircle is provided with gear teeth 38c, the driving force that gear 38c engages in order to be received by meshing part 34 with developing roller gear 40 (see Fig. 2) transfers to developer roll, and geared parts 38 back side is also formed with the gathering sill 38d of guiding guide part 31d.
The installation process of a kind of handle box provided by the invention is described in detail below in conjunction with Fig. 5-7.
See Fig. 5, handle box 1 of the present invention is when disengaged orientation, and the second flexible member 37 applies elastic force to meshing part makes it be in disengaged orientation.
Installation process is see Fig. 6, when handle box 1 of the present invention is mounted in image processing system, the front end of machine driving head 100 has arc surface 102 and plane 101, first arc surface 102 contacts with the compression zone 31a of extensible member 31, along with handle box is installed further, machine driving head 100 applies extruding force F to extensible member 31, extruding force F overcomes the restoring force F1 of the first flexible member, thus extensible member 31 in axial direction X retraction, the deformation component 32 in axial direction X extruding meshing part 34 in extensible member 31 is mounted in retraction process, meshing part 34 is stressed to be rotated around erection column hole clipping 38a, when the plane 101 of machine driving head 100 contacts extensible member 31, the joggle post 34a of meshing part 34 rotates completely to the position of engagement, two projections mesh of itself and machine driving head, thus the driving force that can receive from machine driving head 100.
Unloading process is see Fig. 7, when needing to take out handle box 1 of the present invention, along-direction demounting process cartridge contrary with installation direction, the plane 101 of machine driving head 100 is radially moved relative to extensible member 31, because now joggle post 34a still engages with machine driving head, machine driving head 100 radially extrudes single joggle post 34a, extruded joggle post 34a rotary squeezing deformation component 32, because deformation component 32 has stressed deformable radial deformations 32a, the stressed radial deformation of radial deformations 32a, therefore single meshing part 34 is made to have a small amount of radial displacement, the arc surface 102 of machine driving head 100 contacts compression zone 31a extensible member 31 is stretched out vertically under the effect of the restoring force F1 of the first flexible member 33 subsequently, along with extensible member 31 axially stretches out, extensible member 31 no longer extrudes meshing part 34, under the second flexible member 37 twisting force, meshing part 34 is driven to rotate to disengaged orientation, the taking-up handle box 1 that now can not interfere with machine driving head 100.
Driven unit due to handle box of the present invention arranged telescopic extensible member 31 and drive the meshing part 34 rotating and engage with machine driving head by extensible member, flexible from extensible member 31 of the control of engaging of meshing part 34 and machine driving head 100, and the extension and contraction control of extensible member 31 is from the extruding of machine driving head, this kind of vibrational power flow makes driving head 100 can well engage transmission power with meshing part, there will not be the defect coming off with do not engage.
Deformation component 32 has radial deformations 32a, is squeezed as meshing part provides the displacement of radial direction, handle box can be removed efficiently when dismantling.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
