Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Embodiment
Fig. 1 shows the developer reservoir 1 with a kind of driving connecting member of the present utility model; comprise that is roughly a columned bottle 7; the neck front end of bottle 7 is provided with driving connecting member 3, and the front portion of bottle 7 is provided with the bottle cap 2 that is used for protecting driving connecting member 3, and bottle cap 2 is opened in use.Being provided with a meal outlet, one at the neck of bottle 7 is used for the annular cover 4 of this meal outlet of opening and closing and one and can drives the spring 6 that annular cover 4 is closed meal outlet, the inboard of this annular cover 4 is provided with and is used to the sealing sponge that prevents that carbon dust from leaking outside, sidewall is provided with a pair of chute, thereby makes outlet cap 4 open and close meal outlet under external force when external force loses.Bottle 7 inside are provided with the puddle support that is used to stir powder feeding.There are a base 10 and a dome 11 in the rear portion of bottle 7.
Referring to Fig. 2 to Fig. 4, this driving connecting member 3 constitutes by base 31 with along the driving force acceptance division 32 that axially outwards protrudes out of this base 31, driving connecting member 3 is fastenedly connected in the front end of bottle 7 necks hermetically by its base 31, thereby makes the driving connecting member 3 and the neck of bottle 7 become a coaxial integral body.Described driving force acceptance division 32 has comprised that two driving forces that are anti-" 7 " font receive arm 33,34, two driving forces receive the axis rotation symmetry of arm 33,34 about driving connecting member 3, in addition, in the circular gap of two driving forces reception arms 33,34, also be provided with the reference column that two xsects are " V " font, be used for when driving connecting member 3 cooperates with the drive part 5 of imaging device, providing the location.Because two driving force reception arm 33,34 shapes are symmetrical, existing is example with one of them driving force reception arm 33, and its structure is specifically described.This driving force receives arm 33 and has comprised the circumferential cantilever 332 that extends of sway brace 331 and edge that is connected in base 31 and extension vertically, the outer end of the stiff end of this cantilever 332 and sway brace 331 is connected as a single entity, and the free end of this cantilever 332 is formed with a locking projection triangular in shape 333.See that along axis direction this cantilever 332 roughly is circular-arc.The width that sway brace 331 is connected in the part of base 31 increases from outside to inside gradually, increased the load-bearing capacity that its reception comes from the circumferential driving force of drive part 5.In driving force acceptance division 32 and process that drive part 5 cooperates, sway brace 331 has stronger rigidity and does not deform substantially, and cantilever 332 then has amount of deflection preferably, and it can be around its stiff end at circumferencial direction generation elastic bending deflection.
The front end of cantilever 332 and locking projection 333 thereof is formed with and imports inclined-plane 334, this imports the cooperating of inclined-plane 53 of inclined-plane 334 and drive part 5 porch, make driving force acceptance division 32 successfully be entered in the drive part 5, in the process that enters, cantilever 332 is in circumferencial direction generation elastic deformation, when locking projection 333 enters in the lock hole 51 of drive part 5, cantilever 332 resilience and cooperate fully under himself elastic reaction then with lock hole 51.When drive part 5 when (from driving connecting member 3 to drive part 5) is from rotation around counterclockwise, the driving force receiving plane 339 of locking projection 333 is resisted against on the mating surface 55 of lock rib 54, makes driving connecting member 3 receive the rotary driving force that comes from drive part 5.
The rear end of locking projection 333 is formed with pulls out inclined-plane 335, makes driving connecting member 3 to separate from drive part 5 under external force effect vertically.And the rear end of cantilever 332 also is formed with chamfering inclined-plane 336, tangles and is difficult to make driving connecting member 3 to pull from drive part 5 with the right-angle side of the annulus part 52 of avoiding 5 porch, cantilever 332 driven portions.In addition, the rear end of cantilever 332 also is formed with a baffle plate 337, and this baffle plate 337 can prevent that by the barrier effect of annulus part 52 medial surfaces cantilever 332 outwards is out of shape the excessive driving connecting member 3 that causes and can't be pulled when cooperating with lock hole 51.Be provided with a breach 338 between this baffle plate 337 and the sway brace 331, its effect is the amount of deflection that increases cantilever 332, makes cantilever 332 be easy to take place elastic deformation to pack into or to get loose.
The following brief description course of work of the present utility model, developer reservoir 1 is loaded on the developer reservoir carriage of imaging device, the operating grip of rotation tomography equipment, make the developer reservoir carriage drive the internal motion of developer reservoir 1 to imaging device, simultaneously, the drive part 5 of imaging device is towards developer reservoir 1 motion.At first, the annulus part in the locking projection 333 on the driving connecting member 3 and the drive part 5 52 forms and contacts.Then, continue to make developer reservoir 1 and drive part 5 move toward one another, annulus part 52 compressing locking projections 333, make that cantilever 332 is that the center is around circumferential elastic deformation with its stiff end, thereby locking projection 333 can be coupled in the lock hole 51 in the drive part 5, the driving force receiving plane 339 of locking projection 333 is resisted against on the mating surface 55 of lock rib 54 of drive part 5, makes driving connecting member 3 receive the rotary driving force that comes from drive part 5.Meanwhile, annular cover 4 is produced relative motion with developer reservoir 1, thereby opens meal outlet by imaging device internal mechanism one end pushing tow, and developer reservoir 1 enters applying working condition.When the developer in the developer reservoir 1 exhausts, only need developer reservoir 1 is a little firmly outwards extracted out, can realize separating of driving connecting member 3 and drive part 5.
