Abstract
The utility model relates to an elastic structure of a powder box. The powder box comprises a bracket; a spring chute is formed in the bracket; a spring is arranged at the bottom of the spring chute; the upper end of the spring is equipped with a lining used for fixing the spring and an iron shaft of a developing roller; and the iron shaft of the developing roller is fixed between the top of the lining and the top of the spring chute. According to the utility model, the developing roller and a drum form elastic connection via a spring compensation mechanism and elasticity within a certain range and in the direction of axle centers of the developing roller and the drum to ensure that no gap formed in normal developing is generated during the operation of the developing roller and the drum. The powder box provided by the utility model can overcome defects of the prior art, thereby completely preventing the defects caused by new component design compatibility and a plastic cement material as well as cycle frequency of an OEM power box, and greatly improving production qualification rate and stability.
Description
Technical field
The utility model relates to the printing consumables technical field, especially a kind of powder box elastic construction.
Background technology
The powder box of HP series laser printer (for example HPCP1215,2025,1525 etc.), its visualization way is that contact is developed.Concrete, very close to each other between developer roll and the photosensitive drums, be complete contact-type.If produce the slit between developer roll and the photosensitive drums, will cause the carbon dust on the developer roll not arrive the electrostatic latent image zone on the photosensitive drums through the development bias voltage effectively, thereby cause the print quality defective.And existing compatible powder box is because of designing and material cause the gap between the two that produces when being difficult to avoid developer roll and photosensitive drums in working order fully during batch process, thereby the white piece defective in generation printing sample manuscript edge.
The utility model content
In view of this, be necessary problem, a kind of new structure of avoiding producing between developer roll and the photosensitive drums slit is provided to the prior art existence.
The purpose of the utility model realizes through following technical scheme:
A kind of powder box elastic construction; It comprises a support; Be provided with a spring slide slot in the said support; One spring is arranged at the bottom of said spring slide slot, said spring upper end be provided with one be used for fixing the iron axle of spring and locating development roller lining, the iron axle of said developer roll is fixed between the top of top and said spring slide slot of said lining.
Compared to prior art, the advantage of the utility model is:
The utility model is through the spring compensation mechanism; Make developer roll and photosensitive drums form a kind of Elastic Contact; Through developer roll is applied in the certain limit scope, along the elastic force of developer roll and photosensitive drums axle center direction; The deficiency that guarantee not have the gap when developer roll and photosensitive drums are worked in the normal development, this technology can overcome prior art; Thereby stop fully greatly to improve the stability of production qualification rate and product because of the design of the new part of compatibility and plastic cement material problem, OEM powder box reclaim this defective that frequency problem produces.

Fig. 1 is the powder box one-piece construction cut-open view that has this elastic device;
Fig. 2 is the enlarged diagram at D position among Fig. 2;
Fig. 3 is the powder box elastic construction exploded view of the utility model;
The cut-open view of the powder box elastic construction of Fig. 4 the utility model.
Embodiment
Show that like Fig. 1 Fig. 4 the said powder box that has the elastic mechanism of present embodiment comprises developer roll 1, photosensitive drums 2, is used to control the developer roll stop collar 5 of the spacing between developer roll 1 and the photosensitive drums 2.
Said powder box elastic construction comprises a support 3; Be provided with a spring slide slot 7 in it; One spring 4 is arranged at the bottom of said spring slide slot 7; Spring 4 upper ends be provided with one be used for fixing the iron axle 11 of spring 4 and locating development roller 1 lining 6, the iron axle 11 of said developer roll 1 is fixed between the top of top and said spring slide slot 7 of said lining 6.
Contrast original-pack powder box; The powder box elastic construction of present embodiment has increased elastic mechanism compensation system D; Be designed to spring slide slot 7 to the change of the hole of locating support 3 locating development rollers 1; Produce a flexible automatically space for the location of developer roll 1, realize that whole elastic mechanism can be to the adjustable in pressure joint property of developer roll; Use this patent product; Thereby pressure assurance seamless contact the between the two between the two ends of regulating developer rolls 1 through the spring in the elastic mechanism device 4 and developer roll lining 6 automatically and the photosensitive drums 2; Make developer roll 1 and photosensitive drums 2 very close to each other when powder box work is developed, do not have the phenomenon of turning white thereby realize printing.
The above embodiment has only expressed several kinds of embodiments of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
