Fig. 2 is the decomposition texture synoptic diagram of handle box of the present invention;
Fig. 3 is the structural representation of compeling to push away the unit briquetting of handle box of the present invention;
Fig. 4 is the inside structure synoptic diagram of compeling to push away the unit briquetting of handle box of the present invention.
Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Fig. 1 is the synoptic diagram of handle box of the present invention, and Fig. 2 is the decomposition texture synoptic diagram of handle box of the present invention, and Fig. 3 compels to push away the structural representation of unit briquetting for handle box of the present invention, and Fig. 4 is the inside structure synoptic diagram of compeling to push away the unit briquetting of handle box of the present invention.With reference to Fig. 1～Fig. 4, handle box of the present invention comprises developing cell 1 and photoreceptor unit (not shown on the figure).Developing cell 1 comprises box body 2, developer roll 3, powder feeding roller 20, powder delivery cutter 21 and compels to push away unit 4.
Compeling to push away unit 4 has two, because its structure is identical, only describes one of them at this.Compel to push away unit 4 and be positioned on the another side of box body with respect to developer roll 3, and, compel to push away unit 4 and comprise briquetting 9, flexible member 5 and support 6 near two ends.
Be provided with two on the briquetting 9 symmetrically and close shape mouth 10 and round boss 11,9 one-tenth " U " shapes of briquetting, difference is that the one side that goes up most is plane 9a, making plane 9a here is convenient location, can certainly make the face of other shape.Close shape mouth 10 and preferably extend along boss, its shape can be oval, also can be rectangle.
Also having a face 9b on the briquetting 9, be preferably curved surface, also can be the inclined-plane, and it mainly acts on is to make things convenient for installing process cartridge.
Two sidewalls 11 are arranged on the support 6, two side 11 inwardly respectively becomes a direction recess 11a, respectively there is a pilot hole (not shown on the figure) to reach the reference column 7 that is complementary with the hole on two sidewalls 11, reference column 7 can be pin, peg, can be movable also can after installing, fixing, here repeat no more.
The bottom of support also has a round boss 8.
One end of flexible member 5 is supported by the round boss on support 6 bottoms 8 movably, and the other end is supported by the boss on the briquetting 9 11 versatilely.
Concave surface 11a engagement on the sidewall 9c of briquetting 9 and support 6 sidewalls fixes by the peg on the sidewall 11 7 again.Fixedly under certain pressure, briquetting 9 and support 6 are meshed behind the flexible member 5 when installing, load onto reference column 7 then.
When packing into handle box in imaging device, the face 9b that at first compels to push away unit 4 contacts with the frame of imaging device, under with certain downward dynamics, make handle box pack into then to imaging device, compel this moment to push away unit 4 briquetting 9 plane 9a and imaging device the frame butt and fix.
Compare with traditional handle box, handle box provided by the invention is compeled to push away the unit and is forced developing element to photoreceptor element Elastic Contact by using, make developer roll fully contact with photosensitive drums, and compel to push away the unit and realize by compeling to push away box body, can not cause the distortion of developer roll or photosensitive drums, the user can access good image quality.
The present invention also provides a kind of imaging device, comprises handle box provided by the present invention.Imaging device can be printer, facsimile recorder, duplicating machine and electrophotographic imaging forming apparatus etc.
One of ordinary skill in the art will appreciate that:
The location of briquetting and support and guiding are not limited to above to be mentioned, and at first, shape mouth, gathering sill and the reference column of closing above-mentioned can exchange on briquetting and support.Secondly, above the briquetting that should be mentioned that is the inboard that is positioned at support, but briquetting can also be the outside of support, perhaps can make hollow or solid cylinder to the sidewall of support, and correspondingly the right cylinder that briquetting is made solid or hollow is realized coupling each other.
In addition, compel to push away the structure that element should be not limited to above to be mentioned, can also make such as the known elastic construction of starting writing certainly.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, 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 modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
