Abstract

The utility model discloses a powder box, which aims to provide a simple, convenient and stable chip mounting method. The powder box comprises a housing, a developing imaging component mounted on the housing, a chip, and a chip positioning and fixing structural device; a concave groove is formed on the side wall of the housing; the chip is mounted in the concave groove and fixed in a preset position through the chip positioning and fixing structural device; and when the chip with the quality problem is required to be replaced, the powder box avoids the possibility that other components of the powder box are damaged without disassembling the housing, so that the manufacture and recycling are simpler and more convenient. The utility model has the advantages that the chip is accurately positioned and has low probability of dropping off after being fixed; and the chip is protected by the housing and has low probability of being damaged.

Description

A kind of powder box

Technical field

The utility model relates to a kind of image processing system, and as printer, duplicating machine and facsimile recorder, more particularly, the utility model relates to the powder box that forms the carbon dust image on the photoreceptor of image processing system.

Background technology

Korean Patent Publication No. KR10-2005-0073954, in open day on July 18th, 2005, name is called the toner cartridge of image processing system, and this application case discloses a kind of chip mounting method of powder box.Its method is: chip is installed in the lower part of powder box, the powder box upper part is covered on the lower part that chip is housed again.

The weak point of this method is: chip needs to insert earlier a side of the lower part of housing, the upper part of housing covers on the lower part of housing then, the installation method of this chip has increased the difficulty of product manufacturing and recovery to a certain extent, quality problems have appearred in manufacture process as fruit product, need to change chip, then upper and lower two parts of housing must be taken apart, the miscellaneous part generation problem that might cause product after housing is opened has again increased the manufacture difficulty of product like this.In the recycling of product equally also similar problem can appear.

A kind of chip mounting method also is provided in the prior art.This method is summarized as follows: the back side of chip (contactless) locates to be provided with viscose glue, and chip is attached on the housing respective chip position by viscose glue.Though this method is simple, chip location and fixing all insecure, chip comes off easily, and is not protected, and is vulnerable to ectocine and destroys.

The utility model content

The utility model provides a kind of powder box that has chip location and fixed sturcture in order to overcome shortcoming of the prior art.

The technical solution of the utility model is: a kind of powder box, comprise: housing, be installed in the development image-forming block in the housing, chip, chip location and fixed sturcture device, be formed with " recessed " shape groove in described housing sidewall, chip is installed in " recessed " shape groove, and is fixed with the fixed sturcture device by described chip location.

This chip location comprises at least one screw with the fixed sturcture device, and screw is installed on the housing, and the nut of screw is positioned at a side of chip.Chip location also comprises at least one packing ring with stationary installation, and packing ring is fastening and be positioned at a side of chip by screw.

This chip location and fixed sturcture device or form by at least one button that is formed at housing and is positioned at the chip upside.

The utility model has been realized location to the chip front and back position by " recessed " shape groove, and the location by the side and fixed sturcture device have been realized the above-below direction location to chip.

Compared with prior art, the utility model has the advantages that:

1. when chip generation quality problems need be changed, need not housing is taken apart, avoided to the product miscellaneous part produce infringement may, therefore simple more, convenient on making and reclaiming.

2. chip accurate positioning, fixing back difficult drop-off; Chip is subjected to the housing protection, is difficult for being damaged.

Fig. 5 is the powder box side sectional view chip place partial enlarged drawing of the another kind of embodiment of the utility model.

Embodiment

Fig. 1, Fig. 2 are a kind of embodiment of the present utility model, and powder box 1 comprises housing 2, be installed on the housing 2 chip 3 and to the screw 4 and the packing ring 5 of 3 location of chip and fixation.

As shown in Figure 3, Figure 4, chip 3 inserts in " recessed " shape groove 7 of housing 2, and packing ring 5 is fixing by screw 4, screw 4 comprises nut 8 and screw thread 9, screw 4 is installed on the housing 2 on the corresponding screw hole, and packing ring 5 is pressed in chip 3 contactless sides, to 3 location of chip and fixation.

When the nut 8 of screw 4 was enough big, nut 8 can directly be pressed on chip 3 sides, then need not to adopt 5 pairs of chips location and fixing of packing ring.

Fig. 5 is another kind of embodiment of the present utility model, " recessed " shape groove 7 is arranged on the housing 2, " recessed " shape groove 7 pairing housing upsides have a button 6, button 6 is outstanding and have certain elasticity from housing, give-commission 6 applies a power F, and chip 3 is inserted in " recessed " shape groove, removes power F, button 6 is returned to original state, and button 6 is pushed down the upper side of chip to 3 location of chip and fixation.

Claims
