Abstract

The utility model relates to a developer box and consists of a sensitization drum which is able to supply the developer of the developer box to the developing roller of the sensitization drum, a shell which is able to protect the sensitization drum and the developing roller and is provided with a hub rotating part on the surface and a handle which consists of a protruding arm which is provided with a hub rotation and is connected on the hub rotating part and a connecting plate which is surrounded by the protruding arm; and the distance between the outer edge of the connecting plate and the handle rotating center is a little larger than the largest distance between the axis center of the hub rotating part and the outer surface of the hub rotating part. Therefore the clearance between the connecting plate and the hub rotating part is not enough for the finger; and the utility model is able to effectively prevent the finger from being blocked when operating a developer box and the utility model is safer to be used.

Description

Developing powder box

Technical field

The utility model relates to a kind of developing cell that is used for video generation device, particularly a kind of Developing powder box with folding handle.

Background technology

In video generation device, as Xerox or digital duplicating machine and one printer, be provided with and be used for developing apparatus that the electrostatic latent image that is formed on the photosensitive drums is developed, this developing apparatus is laid in contrasting power on the electrostatic latent image and develops, and the contrasting power that is consumed that develops is generally provided by Developing powder box, this Developing powder box releaseably is installed on the mounting portion that is located at the developing apparatus assigned position, after the contrasting power in the box uses up, with the Developing powder box that more renews.

Existing a kind of Samsung ML-1610 Developing powder box, as shown in Figure 1, this Developing powder box 2 comprises: housing 21, be equipped with contrasting power in it; Developer roll (not shown), its pivotable being installed in the housing 21; And photosensitive drums (not shown), its pivotable being installed in the housing 21.Wherein, photosensitive drums forms electrostatic latent image by the light of exposing unit (not shown) irradiation of video generation device, and developer roll is provided to contrasting power on the photosensitive drums.This Developing powder box also comprises a handle 22, and it has and a pair ofly pivotablely is connected to the projection arm (221,222) of surface of shell and is located at web joint 223 between projection arm (221,222).Handle has the primary importance of unused state and the second place of user mode.Be provided with a projecting platform 211 in handle 22 and the position that housing 21 articulates, make 211 of web joint 223 and projecting platforms be formed with a high about 18mm, be about the vacancy part 23 of 80mm.

When powder box 2 did not use, handle 22 was in folded state, reduced packaging volume when being convenient to pack.When powder box 2 used, deploying handles 22 was put into powder box the darker installation portion of printer and is made it fixing, can print work.But, when needs take out powder box 2 in video generation device, operator custom hold from the side of handle 22 into, what thumb was very natural like this extend in the vacancy part 23.This moment, projecting platform 211 can directly block thumb, thereby damages if powder box overturns.

For this reason, provide a kind of novel Developing powder box real for necessary.

The utility model content

The purpose of this utility model provides a kind of Developing powder box safe in utilization.

For achieving the above object, the utility model provides following technical scheme: Developing powder box comprises: photosensitive drums; Contrasting power in the powder box is provided to developer roll on the photosensitive drums; The housing of protection photosensitive drums and developer roll, its surface has pivot part; And handle, it has the web joint that is connected in the projection arm on the pivot part and is surrounded by the projection arm portion of pivot, and the distance between web joint outward flange and handle rotation center is slightly larger than the ultimate range of the axle center of pivot part to the pivot part outside surface.

Compare with existing Developing powder box, the utlity model has following effect: because the distance between web joint outward flange and handle rotation center is slightly larger than the ultimate range of the axle center of pivot part to the pivot part outside surface, make the gap between web joint and the pivot part be not enough to allow finger stretch into wherein, finger is blocked in the time of can effectively preventing to operate powder box like this, uses safer.

Stereographic map when Fig. 3 is in unused state for the utility model Developing powder box;

Fig. 4 is the exploded view of the utility model Developing powder box handle and housing.

The utility model is described in further detail below in conjunction with each figure and most preferred embodiment.

Embodiment

Referring to Fig. 2 to Fig. 4, Developing powder box 1 comprises housing 11, and contrasting power is housed in it.Have pivot part 111 on the housing 11, pivot part 111 outside surfaces are circumferential surface, and its center has through hole; Developer roll (not shown), its pivotable being installed in the housing 11; And photosensitive drums (not shown), its pivotable being installed in the housing 11.Wherein, photosensitive drums forms electrostatic latent image by the light of exposing unit (not shown) irradiation of video generation device, and developer roll is provided to developer on the photosensitive drums.This Developing powder box 1 also comprises a handle 12, this handle 12 has a pair of projection arm (121,122) and establishes the web joint 123 that is surrounded by projection arm (121,122) part, web joint 123 portion 111 that is pivoted relative to each other has not the outward flange that is surrounded by projection arm (121,122).Projection arm (121,122) is gone up the relative bearing pin (131,132) that is provided with.When inserting in the through hole of pivot part 111 when bearing pin (131,132), handle 12 portion 111 that can be pivoted relative to each other rotates.In the present embodiment, web joint 123 outward flanges and the bearing pin (131 of handle 12,132) distance between the axle center is slightly larger than the ultimate range of the axle center of pivot part 111 to pivot part 111 outside surfaces, so just can guarantee that web joint 123 portion 111 that is pivoted relative to each other rotates smoothly, guaranteed that simultaneously the slit between web joint 123 and the pivot part 111 is not enough to allow finger pass, and can avoid finger to be hindered by card.Handle 12 also can be connected with pivot part 111 by similar structures such as hinges, as long as can guarantee handle 12 with respect to housing 11 rotation, and the ultimate range that pivot part 111 outside surfaces are arrived in the axle center that is slightly larger than pivot part 111 of the distance between web joint 123 outward flanges and handle 12 rotation centers gets final product.As shown in Figure 2, when powder box was in user mode, handle 12 was opened; As shown in Figure 3, when powder box was in unused state, handle 12 was folded to housing 11 upper surface places, the volume in the time of can reducing compact package like this.
