Abstract

The utility model relates to a consumptive material for a laser printer, in particular to a general developer box which can be used for printers of different series. The developer box comprises a shell forming a carbon powder bunker by encirclement and a down concave chip groove which is arranged on the outer surface of the shell and used for installing chips. Two threaded-hole stations which are arranged on left and right are arranged in the chip groove the inside of which is also provided with three lug bosses the top surfaces of which and all the threaded-hole stations have the same plane. A chip is selectively supported on one of the threaded-hole stations and at least two lug bosses, and is fixed in the chip groove by a screw. The developer box of the utility model can be suitably applied to printers of different series.

Description

Developer box

Technical field

The utility model relates to the laser printer consumptive material, especially a kind of universal developer box that can use on the printer of different series of being used for.

Background technology

In existing laser printer, the developer box of storage developer all is to be removably mounted in the printer.Usually, the employed developer box of the printer of same serial different model is also incomplete same, and a kind of developer box of structure only is applicable to a kind of printer of model.For example, developer box shown in Figure 1 only is used for the printer of first model; Developer box shown in Fig. 3 only is used for B-mode number printer.Pack into B-mode number printer of developer box shown in Figure 1 then can not be worked, and in like manner, pack into the printer of first model of developer box shown in Figure 3 can not be worked.A kind of developer box of structure only is used for a kind of printer of model, and this has increased manufacturer's production cost and customer using cost undoubtedly, has also increased the complicacy of manufacturer's production and the complicacy that the user uses thereof simultaneously.

Summary of the invention

The purpose of this utility model provides a kind of developer box that can be common to a series of multiple model printers.

For achieving the above object, the utility model provides following technical scheme: developer box comprises

Surround the housing of toner;

Be positioned at the following concavity chip groove that is used to install chip on the housing outer surface;

Be provided with the threaded hole platform of arranging about two in the described chip groove;

Wherein,

Also be provided with three boss in the described chip groove, the end face copline of each threaded hole platform and boss;

One chip is supported on one of them threaded hole platform and two boss selectively at least, and by a screw retention in the chip groove.

The utility model developer box is compared than prior art, has changed the structure in the chip groove, has changed the position of the threaded hole that is used for fastening chip, has increased the boss that is used for supporting chip simultaneously.Like this, just go for the printer of different series by the placement location that changes chip.Become a bit fastening (a place screw thread) by original fastening (two place's screw threads or a screw thread add a pin) at 2, cooperate the fixing of chip but set up boss.

For realizing better technique effect, better technical scheme is:

Described chip is supported on a threaded hole platform and two boss, this threaded hole platform and this two boss distribution triangular in shape in described chip groove.

Can make the installation of chip more stable by the boss that increases supporting chip.

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment

Developer box generally comprises toner, and puddle support and developer roll are installed in the toner, and stirring vane is housed on the puddle support; The toner housing outer surface is provided with the following concavity chip groove that holds chip.

Referring to Fig. 1 to Fig. 4, in the prior art, first kind of developer box 10 is different with the structure that second kind of developer box 20 key distinction is chip grooves on the housing.

Chip groove on developer box 10 housings as shown in Figure 1 and Figure 2, its concrete structure is as shown in Figure 2.For developer box 10, mainly with the mode that the threaded hole platform 111,112 of chip groove 11 cooperates chip is fixed in the chip groove 11 by two screws; On the plane that Fig. 2 shows, chip groove 1 width be D1, highly for H1, threaded hole platform 111 to chip groove 11 right side wall back gauge D2, threaded hole platform 112 to chip groove 11 right side walls apart from being that D3, threaded hole platform 111,112 are H2 to the distance of chip groove 11 upper walls.In addition, in chip groove 11, lay stablely, be provided with the coplanar boss 113 of one and two threaded hole platforms in the bottom of chip groove 11, with the supported at three point of formation to die bottom surface for guaranteeing chip.

Chip groove 21 on developer box 20 housings as shown in Figure 3, Figure 4, its concrete structure is as shown in Figure 4.The bottom supporting of chip register pin platform 212, threaded hole platform 211 and with both coplanar boss 213 on, form supported at three point to die bottom surface, simultaneously, cooperate the tightening of realization to chip by screw and threaded hole platform 211.On the plane that Fig. 4 shows, chip groove 21 width be d1, highly for h1, threaded hole platform 211 to chip groove 2 right side walls distance for d2, register pin platform 212 to chip groove 2 right side walls apart from being that d 3, register pin platform 212, threaded hole platform 211 are h2 to the distance of chip groove 2 upper walls.

Be applicable to respectively that as mentioned above the utility model is realized same developer box general to these two kinds of model printers by the structure of improving the chip groove with the difference of two kinds of developer boxes of a series of two kinds of model printers.Its specific embodiment as shown in Figure 5 and Figure 6, respectively there is a threaded hole platform 312,311 at two ends, chip groove 31 left and right sides on developer box 30 housings, and be positioned at three boss 313,314,315 of chip groove 3, the end face copline of 312,311 and three boss 313,314,315 of threaded hole platform, boss is used for supporting chip, makes chip more stable.Chip is supported on one of them threaded hole platform and two boss selectively, and by a screw retention in chip groove 3.When developer box 30 and aforementioned developer box 10 are general, chip is placed on the right-hand member of developer box 30 chip grooves, and threaded hole 311, boss 314,315 supporting chips steadily are placed on the powder storehouse 31, with a screw retention, it is of a size of DD2 and equals that D2, HH1 equal H1, HH2 equals H2.When developer box 30 and aforementioned developer box 20 are general, chip is placed on the left end of developer box 30 chip grooves, threaded hole 312, boss 313,315 supporting chips, steadily be placed on the powder storehouse 31, with a screw retention, wherein dimension D D1 equals d1, DD3 and equals that d3, HH1 equal h1, HH2 equals h2.So according to the developer box 30 of this scheme implementation, can fall into the corresponding chip induction of aforementioned first series printer groove, also can fall into the corresponding chip induction of second series printer groove.

Certainly, above-mentioned boss is mainly used in supporting chip, and therefore, its quantity and placement location can be made appropriate change according to general knowledge.

The structure composition of the utility model carbon dust tube is not limited to above-mentioned embodiment.Conspicuous change is carried out in prompting according to the foregoing description, and other every changes that do not break away from essence of the present invention, all should be included within the described scope of claim.
