The developer box that the utility model provides; Through elastic device is set on box body; Compel to push away the photoreceptor unit through elastic device, need not developing cell to be offered different dies, thereby strengthened the versatility of developing cell for satisfying different photoreceptor unit; Reduced the cost of production, accumulating and sale, made that also user's use is more convenient.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do one to the accompanying drawing of required use in embodiment or the description of the Prior Art below introduces simply; Obviously, the accompanying drawing in describing below is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the developer box that the utility model provided;
Fig. 2 is the cut-open view of Fig. 1 along the B-B direction;
Fig. 3 is provided for the utility model embodiment one removes the structural representation of the developer box behind the elastic device;
The structural representation of the elastic device that Fig. 4 is provided for the utility model embodiment one;
Fig. 5 is provided for the utility model embodiment two removes the structural representation of the developer box behind the elastic device;
The structural representation of the elastic device that Fig. 6 is provided for the utility model embodiment two.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, intactly description; Obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is the structural representation of the developer box that the utility model provided; Fig. 2 is the cut-open view of Fig. 1 along the B-B direction; Fig. 3 is provided for the utility model embodiment one removes the structural representation of the developer box behind the elastic device, the structural representation of the elastic device that Fig. 4 is provided for the utility model embodiment one.With reference to Fig. 1～Fig. 4, the developer box of the utility model comprises developing cell 1 and photoreceptor unit (not shown on the figure).Developing cell 1 comprises box body 3, developer roll 5, powder feeding roller 6, powder delivery cutter 7, puddle support 8 and elastic device 2.
There is one to be positioned at conplane handle 33, and the groove 30 that is positioned at handle 33 belows, and two symmetrically arranged limiting components 31 on the end of developer box 1 with box body 2 upper surfaces.
Limiting component 31 comprises limited block 31a and guide groove 31b.
After elastic device 2 was encased in box body 1, breach 23 matched with limited block, was specially guide groove 31b and was embedded in the middle of the breach 23, and limited block 31a is positioned at breach 23 tops and briquetting 20 butts, prevents that briquetting from coming off.Elastic device 2 is under the effect that is under pressure, and briquetting 20 can be along the guide groove to-and-fro movement.
The developer box that present embodiment provides; When developing cell 1 is encased in photosensitive unit; The elastic device 2 of developing cell 1 and the framework butt of photosensitive unit, framework is given 2 one urgent thrusts forward of developing cell, makes the developer roll 5 of developing cell 2 fully contact with the photosensitive drums of photosensitive unit.Simultaneously; A sealing opening is arranged on the photosensitive unit framework; The convexity 21 of elastic device 2 upper holder blocks 20 and the opening clamping on the photosensitive unit; Can realize the locking of developing cell 1 and photosensitive unit thus, so also just can become developer box to be encased in imaging device with photoreceptor unit one developing cell.In the time will taking off developing cell, because convexity is the arc convex piece, so only need pin the photoreceptor unit framework on the other hand, an other hand is up carried the handle of developing cell, just can take off developing cell from the photoreceptor unit easily.
Embodiment two
Present embodiment and embodiment one something in common are this no longer superfluous chatting.
Fig. 5 is provided for the utility model embodiment two removes the structural representation of the developer box behind the elastic device, the structural representation of the elastic device that Fig. 6 is provided for the utility model embodiment two.Like Fig. 5 and shown in Figure 6, developer box that present embodiment provided and embodiment one difference are that elastic device 2 is different with developing cell 1 matching relationship.
Developing cell 1 comprises box body 3, handle 33 and is positioned at the groove 30 of handle below, and is installed on the elastic device 2 between handle 33 and the groove 30.
Also include two two guided ways 32 that are mutually symmetrical and are provided with on the box body 3, guided way 32 is positioned at the end of groove 30 near handle.
After elastic device 2 is encased in this developing cell, when elastic device receives a force of compression, briquetting 20 will turn an angle along axle 24, give thrust forward of box body simultaneously.
The developer box that present embodiment provided; After developing cell is encased in photosensitive unit; The framework butt of elastic device and photosensitive unit, power of framework retroaction is given developing cell thus, and the developer roll of compeling thus to push away in the developing cell fully contacts with the photosensitive drums of photosensitive unit.Simultaneously, the locking of developing cell and photosensitive unit is accomplished in convexity on the briquetting and the sealing opening clamping on the framework thus.In the time will taking off developing cell, because convexity is the arc convex piece, so only need pin the photoreceptor unit framework on the other hand, an other hand is up carried the handle of developing cell, just can take off developing cell from the photoreceptor unit easily.
Compare with traditional developer box, the developer box that the utility model provided is provided with elastic device through the rear end at box body, compels to push away the framework of photosensitive unit through elastic device, makes developer roll fully contact with photosensitive drums.Make that so same developing cell can general different photoreceptor unit, practiced thrift cost, also convenient user's use.
What should explain at last is: above embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to previous embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the spirit and the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
