See Fig. 2, photosensitive drums protective cover 03 lower end is formed with buckle 0331 and 0332, buckle 0331 and 0332 matches with the draw-in groove be formed on housing 021, and the lower end of photosensitive drums protective cover 03 is removably fastened on the housing 021 of developing cell 02.When on the housing 011 that the upper end of photosensitive drums protective cover 03 is fastened on drum unit 01, biside plate 0341 and 00342 fastens on the two ends of handle box accordingly.So must have an effect to the upper plectrum 032 of photosensitive drums protective cover 03, just photosensitive drums protective cover 03 can be taken off.
See Fig. 3, the inflow point of waste powder hopper is rotatably provided with photosensitive drums 012, and the some work face of photosensitive drums 012 is exposed.The exit in powder storehouse is rotatably provided with developer roll.Developing cell 02 is fixedly connected with by being connected pin 04 with the junction at drum unit 01 two ends, thus drum unit 01 can be rotated around connection pin 04 relative to developing cell 02, and left end both being kept by the elastic supporting member for supporting optical member of being located at right-hand member against together, thus can effectively guarantee that the workplace of developer roll and the workplace of developer roll keep predetermined gap.
In the process of taking off photosensitive drums protective cover 03; press with thumb and on plectrum 032, promote photosensitive drums protective cover 03 and taken off, but be limited to the size of plectrum 032, thumb is difficult to have an effect; and easily skid, be not easy photosensitive drums protective cover 03 to take off from handle box.
Summary of the invention
The purpose of this utility model is to provide a kind of handle box being convenient to take off photosensitive drums protective cover.
To achieve these goals, the utility model provides a kind of handle box, and it comprises drum unit, developing cell, photosensitive drums protective cover and connects pin, and drum unit rotatably connects by being connected pin with developing cell; The housing of drum unit surrounds the waste powder hopper for holding useless powder, and the inflow point of waste powder hopper is rotatably provided with photosensitive drums; The housing of developing cell surrounds the powder storehouse for holding carbon dust, and the exit in powder storehouse is rotatably provided with developer roll; One end of photosensitive drums protective cover is removably connected by buckle and coordinating of draw-in groove with the housing of developing cell, and the other end of photosensitive drums is fastened on the housing of drum unit, and photosensitive drums protective cover covers in outside the exposed workplace of photosensitive drums; The edge that photosensitive drums protective cover is fastened on one end of drum unit is formed with a plectrum extended along the direction away from this drum unit; The outside surface of drum unit housing is formed with the crown groove of an ellipsoid, the crown groove of this ellipsoid is positioned at the below of plectrum.
From above scheme, outside surface due to drum unit housing is formed the crown groove of an ellipsoid, and the crown groove of this ellipsoid is positioned at the below of plectrum, user is in the process of taking off photosensitive drums protective cover, and thumb can put into the crown groove of ellipsoid, and presses on plectrum, thus be convenient to thumb and have an effect, and be not easy to skid, compared with prior art, be more convenient for taking off photosensitive drums protective cover; Because groove is ellipsoid coronal structure, be convenient to the delivery in housing injection moulding process, and save material.In addition, because groove is ellipsoid coronal structure, in the process of handle box reclaiming, the useless powder in waste powder hopper can not residue in waste powder hopper because the sidewall of waste powder hopper being formed with a projection, is convenient to reclaim the regeneration of handle box.
Concrete scheme is axial arranged along photosensitive drums of the long axis direction of the crown groove of ellipsoid.Be convenient to take off photosensitive drums protective cover.
More concrete scheme is the maximum length of the crown groove of ellipsoid, the value of breadth extreme and depth capacity is respectively 6 millimeters.The groove with this size better can adapt to the size of thumb, is convenient to take off photosensitive drums protective cover.
