Description
Technical field
The imaging device that the utility model relates to a kind of Delevoping cartridge and comprises this Delevoping cartridge.
Background technology
Conventionally, imaging device by laser instrument, accommodate the acting in conjunction of the parts such as Delevoping cartridge and transfer roll of carbon dust, complete development and the transfer printing of carbon dust on paper, wherein, Delevoping cartridge comprises the parts such as charging roller, photosensitive drums, developer roll and powder feeding roller.Development and the transfer process of carbon dust are as described below, first, charging roller is to photosensitive drum charging, make certain electric charge on photosensitive drum surface band, then laser instrument, to photosensitive drums Emission Lasers, forms the electrostatic latent image corresponding to required image on the surface of photosensitive drums, then developer roll is reprinted carbon dust to photosensitive drums, make the electrostatic latent image of photosensitive drum surface become visual carbon dust image, last transfer roll is transferred to the carbon dust image in photosensitive drums on paper, thereby makes the paper can document image.
For guaranteeing good picture quality, photosensitive drums need to maintain stable rotational speed.In tradition Delevoping cartridge, photosensitive drums is rotatably supported on Delevoping cartridge by back shaft, back shaft can rotate with the rotation of photosensitive drums, if but back shaft rotates, this back shaft tends to because the rotation of self produces erratic beating, this beating can be added in photosensitive drums, causes the rotational speed of photosensitive drums to change, rotation that can not be stable.
For fear of above-mentioned generation of beating, back shaft need to non-rotatably be fixed on Delevoping cartridge, rather than rotates together with photosensitive drums.
Fig. 1 shows the anti-rotation structure in traditional Delevoping cartridge, conventionally the axle head of back shaft 100 is designed to D shape, then this D oblique crank Z end 100 is inserted on Delevoping cartridge end cap in corresponding D shape hole 101, realizes the anti-rotation function of back shaft.But the assembling between this D oblique crank Z end 100 and D shape hole 101 often needs higher precision, packaging technology requires high.The axle head 100 of this back shaft is installed to D shape hole 101 when interior, if not alignment mutually, axle head 100 will be withstood, in cannot patchhole 101, need artificial constantly rotation support shaft, after axle head 100 and hole 101 are fitted like a glove, can install, in the time that production quantity is larger, increase undoubtedly workman's work burden, efficiency of assembling is low.
Utility model content
The utility model provides a kind of Delevoping cartridge, high as effectively preventing that the rotation of photosensitive drum shaft from causing the packaging technology accuracy of photosensitive drum shaft to require to solve existing Delevoping cartridge, the technical matters that efficiency of assembling is low.
For achieving the above object, the technical scheme that the utility model is taked is:
A kind of Delevoping cartridge, comprising:
Housing;
Photosensitive drums, rotatable being arranged in described housing;
Photosensitive drum gear, is arranged on the end of described photosensitive drums, for receiving driving force, drives photosensitive drums to rotate together;
End cap, is arranged on the end of described housing, and this end cap is provided with spacing hole;
Back shaft, for supporting above-mentioned photosensitive drums, the end of this back shaft is arranged in described spacing hole;
It is characterized in that, described spacing hole inner side is provided with stop part, and the end of described back shaft is provided with the retainer corresponding with stop part, and described retainer can relatively described stop part in described spacing hole be rotated within same direction is less than the scope of a week.
When described retainer rotates to the position of stop part in described spacing hole, retainer is proceeded relative rotation to stop described back shaft described in described stop part butt.
Described stop part is a projection, and described retainer is " one " font.
The xsect of described retainer is triangle.
The xsect of described retainer is D font.
The xsect of described retainer is cruciform.
Described retainer is at least one.
Described stop part is at least one.
The utility model also provides a kind of imaging device, comprises Delevoping cartridge, it is characterized in that, described Delevoping cartridge is above-mentioned arbitrary Delevoping cartridge.
Adopting after technique scheme, because described retainer can relatively described stop part in described spacing hole be rotated within same direction is less than the scope of a week, in the time that back shaft is installed, arbitrary position that retainer only need be placed in the scope that can rotate relative to stop part in spacing hole all can complete assembling, do not need accurate aligning, easy for installation, alleviate workman's work burden, improve the efficiency of assembling of product.Having solved existing Delevoping cartridge is that the rotation that effectively prevents photosensitive drum shaft causes the packaging technology accuracy requirement of photosensitive drum shaft high, the technical matters that efficiency of assembling is low.
