Abstract
The utility model discloses a driving force transmission component for use in a processing box, comprising a body which is provided with a driving force transmission gear, wherein lugs which withstand the driving force are arranged on the body, and guide surfaces are formed on the front ends of the lugs. Due to design of the guide surfaces on the front ends of the lugs, the lugs are more easily to fall into concave holes of a driving force output head. During the movement of the driving force output head toward the lugs, the lugs can be self-guided to fall into the concave holes to form a stable fit with the concave holes as long as the orifice edges or the inner side faces of the concave holes contact the guide surfaces on the front end of the lugs and slide in along the guide surfaces, thereby saving a complex pre-positioning structure on a frame of the processing box, reducing the difficulties in the die sinking and the material cost of the frame of the processing frame and simplifying the structure. Moreover, the utility model also provides the processing box which adopts the driving force transmission component.
Description
Technical field
The utility model relates to a kind of driving force transferring elements that is used on the handle box, and the handle box with this driving force transferring elements.
Background technology
Such as image forming apparatus such as laser printer, duplicating machine, facsimile recorder usually use dismountable handle box as a supplement carbon dust container and be engaged in it and form image on the medium.The required driving force of handle box moving component is provided by the motor in the image forming apparatus.The driving force kind of drive between the driving force acceptance division of handle box and the driving force output mechanism of motor mainly contains two kinds: a kind of is as U.S. Pat 4,829,335 handle boxes that disclose, the driving force transferring elements of this handle box comprises the cross helical gear that is located at photosensitive drums one end, the cross helical gear of photosensitive drums is meshed on cross helical gear by driver part on the image forming apparatus and the handle box, to drive the photosensitive drums rotation.Another kind is the handle box that discloses as Chinese patent CN1217241C, the driving force transferring elements of this handle box comprises the on-circular cross-section projection of stretching out from photosensitive drums one end, and the on-circular cross-section engaging hole of driving force delivery matches to accept and transmission of drive force makes the photosensitive drums rotation on this on-circular cross-section projection and the image forming apparatus.
A kind of handle box that adopts above-mentioned second kind of power transmission mode as shown in Figure 1, it mainly is made of the powder storehouse 1 that holds carbon dust and a waste powder hopper 2 of accommodating useless powder, moving components such as puddle support, powder feeding roller, developer roll are arranged in the powder storehouse 1, moving component in the waste powder hopper 2 is a photosensitive drums, in addition, also have charging roller and cleaning doctor etc.Photosensitive drums is as a vitals of handle box, comprises the drum type cylindrical shell of being made by conductive materials and has a pair of bulging flange of axial region, and the drum flange is provided with gear, in order to other moving component transmission of drive force in handle box.Photosensitive drums rotatably is supported between two sidewalls 4 of waste powder hopper 2 by above-mentioned two bulging flanges.One of them drum flange stretches out from the circular hole of a sidewall 4 as the driving force transferring elements, and this circular forms a circular hole flange 41.Being provided with a cross section on the axial region front end face of driving force transferring elements is leg-of-mutton distortion columnar projections 3.In addition, the on-circular cross-section projection of power transmission member also can adopt non-distortion columnar projections 9 forms shown in Figure 2.In Fig. 2, motor 5, gear 6, gear 7 and the 8 usefulness double dot dash lines of driving force delivery in the image forming apparatus are represented.In the time of in photosensitive drums (handle box) is packed image forming apparatus into, driving force delivery 8 will axially moving to left along gear 7, shrinkage pool identical with protruding 9 xsects entangles projection 9 on it, and contact, thereby finish the moment of torsion transmission of motor 5 to photosensitive drums (handle box) with a side 92 of projection 9 corner part 91.
Be installed in the process of image forming apparatus at handle box, in order to make the projection on the driving force transferring elements can successfully fall in the shrinkage pool of driving force delivery, usually need to adopt pre-determined bit structure as shown in Figure 1 at present, promptly on the inner peripheral surface of circular hole flange 41 around the some ribs that extend vertically that circumferentially evenly distribute, the front end of every rib forms a spigot surface that tilts, the driving force delivery slips into along described spigot surface in the process near projection 3, to obtain good location.This pre-determined bit structure is formed on the handle box framework, and its complex structure has increased mould design difficulty and material cost.
Summary of the invention
First purpose of the present utility model provides a kind of driving force transferring elements that is used on the handle box, and it is simple in structure, the driving force delivery of image forming apparatus is successfully imported, and can reduce the die sinking difficulty and the material cost of handle box framework.
Second purpose of the present utility model provides a kind of handle box that adopts above-mentioned driving force transferring elements.
For realizing above-mentioned first purpose, the utility model provides a kind of driving force transferring elements, comprises having the body that driving force is transmitted gear, and this body is provided with the projection of accepting driving force, and the front end of described projection is formed with spigot surface.
Since in the Front-end Design of projection spigot surface, thereby can successfully fall in the shrinkage pool of driving force delivery.At the driving force delivery in the process that projection moves, as long as the orifice edge of its shrinkage pool or the spigot surface that internal face touches protruding front end, can slip into along this spigot surface, projection is successfully fallen into by leading certainly also form stable cooperation in the shrinkage pool with it, thereby saved pre-determined bit structure complicated on the handle box framework, reduced the die sinking difficulty and the material cost of handle box framework, simplified the structure.
Further, described spigot surface can be clinoplane, the front end of projection is attenuated, thereby more easily fall in the shrinkage pool of driving force delivery.In addition, spigot surface can also be outer convex globoidal.
Concrete preferably scheme is, described body also has along driving force and transmits gear shaft to the axial region that stretches out, and described projection can be stretched out vertically from the front end face of axial region.Described projection is three right cylinders that are evenly distributed on circumference of axial region front end face, and the center of circle of this circle is positioned on the axis of described axial region, and wherein the side of every right cylinder is provided with at least one anticreep groove that is basically perpendicular to described axis.When above-mentioned projection cooperated with the shrinkage pool of driving force delivery, the orifice edge engagement by anticreep groove and shrinkage pool realized transmission, made stressed more concentratedly, and transmission is more reliable; In transmission process, the driving force delivery can not be separated from the driving force transferring elements of handle box, and the reliability of transmission, stability and print quality are further guaranteed.
Another kind of scheme is that the front end face that described projection is transmitted gear from described driving force stretches out vertically.Described projection is three right cylinders that are evenly distributed on circumference of described front end face, and the center of circle of this circle is positioned on the axis of described driving force transmission gear; Wherein, the side of every right cylinder is provided with at least one anticreep groove that is basically perpendicular to described axis.
