Detailed description of the invention

Below in conjunction with the accompanying drawings, embodiment of the present utility model is described in detail.Should be appreciated that described herein Specific embodiment, only in order to explain this utility model, is not used to limit this utility model.

First, as shown in Figures 1 to 3, the handle box that this utility model provides includes developing device 1 and photosensory assembly 20.Aobvious The installation of shadow assembly 1 dismounting is in photosensory assembly 20, including having the housing 2 of developer containing part, and the development of bearing developer Roller 3, for locking the locking mechanism 4 in developing device 1 to photosensory assembly 20.Housing 2 has the first side wall 2a and the second sidewall 2b, developer roll 3 is rotatably arranged between the first side wall 2a of housing 2 and the second sidewall 2b, and the axis of developer roll 3 is first Sidewall 2a upwardly extends towards the right and left between the second sidewall 2b.Developer roll 3 is arranged on the front end of housing 2 relative to housing 2. At housing 2, the rear end of developer roll 3 is provided with the first in command 13.Optical assembly 20 includes that framework 21, framework 21 include the 3rd Sidewall 21a, the 4th sidewall 21b and the diapire 21c extended between the 3rd sidewall 21a and the 4th sidewall 21b, Electrifier frame, photoreceptor 22 can Rotate is arranged on framework 21, and it has the axis extended from the 3rd sidewall 21a towards the 4th sidewall 21b, here by photosensitive One end of component 22 place framework 21 is referred to as the front end of framework 21, is arranged on the second of framework 21 rear end relative to Electrifier frame, photoreceptor 22 Handle 25, is provided with lever 24 on the 4th sidewall 21b, and lever 24 can be around a fulcrum.In order to reduce photosensory assembly 20 Frame size, further reduces manufacturing cost, and the second in command 25 is arranged on the bottom of framework 21 rear end, specifically, at frame Frame is liked to be not provided with rear wall relative to the offside of Electrifier frame, photoreceptor 22 on 21.This set, so that the housing 2 of developing device 1 Protruding from the rear end of the framework 21 of photosensory assembly 20, it is bigger that developing device 1 can do, and photosensory assembly 20 need not accordingly Do big.

As Fig. 4 is to shown in 5, and the side of developing device 1, the locking mechanism of the developing device that this utility model provides includes activity Bar 5 and torsion spring 6, motion bar 5 comprises main body bar 5a, sticking department 5b, first free end installation portion 5c, spiral installation portion 5d, torsion spring 6 Comprise helical body 6c, the first free end 6a and the second free end 6b.One side of housing 2 is provided with the second free end installation portion 8, installation portion 9 it is provided with in housing bottom, the powder cabin part of housing 1 comprises the first receiving portion 12 and the second receiving portion 11, and first Receiving portion 12 has the first puddle support (not shown), and the second receiving portion 11 has the second puddle support (not shown), peace Dress portion 9 is arranged between the first puddle support of the first receiving portion 12 and the second puddle support of the second receiving portion 11.When installing locking During mechanism, motion bar 5 inserts in installation portion 9, and helical body 6c of torsion spring 6 is installed to spiral installation portion 5d, the first free end 6a Installing to the first free end installation portion 5c, the second free end 6b installation is to the second free end installation portion 8, then fixes with screw 7 State installation portion at 3.It is provided with holding section 5e and bending part 5f on motion bar 5, installation portion 9 is provided with connecting hole 9a and support 9b, support 9b have hollow structure, after the main part 5a of motion bar 5 is through multiple support 9b, holding section 5e through connecting hole 9a The periphery of connecting hole 9a, bending part 5f is stopped restriction described motion bar 5 shifting in the lateral direction by the first side wall 2a of housing 2 Dynamic.Optionally, it is less that the diameter of connecting hole 9a can make the diameter than the main part 5a of movable part, so has only to card Conjunction portion 5e can complete the location of movable part 5 through connecting hole 9a.So, motion bar 5 is rotatably mounted to the end of housing 2 Portion.The bottom that motion bar 5 is installed to housing 2 can avoid motion bar 5 to do with the parts in developing device 1 and photosensory assembly 20 Relating to, make the gap between the bottom of developing device 1 and the bottom of photosensory assembly 20 be utilized simultaneously, the structure of handle box is also Compacter, thus the overall dimensions of handle box can be reduced.

As shown in figures 6 a and 6b, it is the lock-out state of developing device and photosensory assembly, now, developer roll 3 and photosensitive structure Part 22 contacts, and this position is referred to as contact position, and now, sticking department 5b contacts with the second in command 25, and catches on the second in command 25, turns round The elastic force of spring 6 makes what sticking department 5b can be stable to catch on the second in command 25 and do not get loose.Optionally, sticking department What 5b can also be arranged engages with remaining groove position in photosensory assembly.

As illustrated in figs. 7 a and 7b, when needing to release the locking between developing device and photosensory assembly, user applies one Power F is to lever 24, and the clicking section 24a of lever 24 stirs the first free end installation portion 5c on motion bar 5, and makes motion bar 5 Rotating, the sticking department 5b of motion bar 5 is disengaged from the second in command 35, when lever 24 continues to rotate, and clicking section 24a will lead to Cross and on the first free end installation portion 5c, promote developing device 1 to make developing device move further into a developer roll 3 and photosensitive The position that component 22 separates, this position is referred to as separation point position.Optionally, the first free end installation portion 5c is as developing device In 1, the power acceptance division of locking mechanism is a preferred version, it is of course also possible to select remaining part to receive thick stick as power acceptance division The power of bar 24, such as, arranges another one on revolving part 5 and is not used in the projection of the first free end installation portion 5c and joins with lever 24 Merge the thrust receiving lever 24, equally release the lock-out state between developing device 1 and photosensory assembly 20.

In the present embodiment, after being arranged to the motion bar in the locking mechanism in developing device rotate locking simply one excellent Selecting embodiment, optionally, the motion of motion bar can also be slidingtype, is slided too by lever pushing motion bar The lock-out state of developing device and photosensory assembly can be released.

The handle box that the present embodiment provides, by arranging rotatable motion bar, in photosensory assembly in developing device Lever is set, motion bar locking developing device to photosensory assembly, the lever in press sense optical assembly can promote motion bar rotate with Releasing developing device and the locking of photosensory assembly, simple in construction, locking is stable, solves and needs change user to make in prior art By the unstable technical problem of custom and locking.

Above example only in order to the technical solution of the utility model to be described, is not intended to limit；Although with reference to aforementioned reality Execute example this utility model has been described in detail, it will be understood by those within the art that: it still can be to front State the technical scheme described in each embodiment to modify, or wherein portion of techniques feature is carried out equivalent；And these Amendment or replacement, do not make the essence of appropriate technical solution depart from spirit and the model of this utility model each embodiment technical scheme Enclose.
