Abstract
The utility model discloses a detection hole structure which aims to provide a detection hole structure with simple structure, low cost and convenience in manufacturing and installing. The detection hole structure comprises a detection window (1) and a transparent plug (8), wherein the transparent plug (8) is arranged on the detection window (1) and is in interference fit with the detection window (1); and the outer side of the transparent plug (8) is provided with a groove (11). The detection hole structure can be widely applied in the field of the toner cartridge.
Description
Technical field
The utility model relates to a kind of detection mouth structure.
Background technology
Along with people's becomes increasingly high to the requirement of printing technique, and laser printer just arises at the historic moment.Laser printer can be used as electrophotographic image and generates equipment, can also print as paper as general printer, and its function is many-sided.The employed cartridge of laser printer is installed on the laser printer removably, is used for carbon dust to laser printer being provided, at present; For cartridge can better go work, the sidewall of cartridge is provided with the detection mouth structure that is used to detect the carbon dust surplus, and is as shown in Figure 1; This detection mouth structure comprise detection window 1 and with the suitable transparent plug 2 of buckle-type of detection window 1; Extension limiting section (3,4), the inboard that transparent plug 2 sidewalls of this buckle-type are provided with two symmetries is provided with boss, arranged outside that sealing gasket is installed has at least one lug boss 5, and the cartridge box body is provided with two clamping parts (6,7), be encased in the transparent plug 2 of this buckle-type in the detection window 1 after; Pin lug boss 5 rotations; Make extension limiting section (3,4) be positioned at clamping part (6,7) below, blocked by clamping part (6,7), thus the transparent plug 2 of locking buckle-type; Such structure more complicated; And make and install more loaded down with trivial details, and also need increase sealing gasket in addition and cost is higher, so just there is this certain weak point.
The utility model content
The utility model technical matters to be solved is the deficiency that overcomes prior art, provide a kind of simple in structure, cost is lower, manufacturing and detection mouth structure easy for installation.
The technical scheme that the utility model adopted is: the utility model comprises detection window, transparent plug, and said transparent plug is arranged on said detection window place and said detection window interference fit.
Said detection window is a counterbore, the said transparent boss that is provided with beyond the Great Wall, and said transparent plug and said counterbore are suitable, the aperture interference fit of said boss and said counterbore.
The arranged outside of said transparent plug is fluted.
The beneficial effect of the utility model is: because the utility model comprises detection window, transparent plug; Said transparent plug is arranged on said detection window place and said detection window interference fit; Compared with prior art, it has omitted sealing gasket, simultaneously; Simplified the structure of cartridge box body and transparent plug; And installing and locating gets final product through said transparent plug is filled in said detection window, has avoided rotating the trouble that transparent plug makes its aligned position, so the utility model is simple in structure, cost is lower, manufacturing and easy for installation.

Fig. 2 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, existing detection mouth structure comprise detection window 1 and with the suitable transparent plug 2 of buckle-type of detection window 1, the extension limiting section 3 that transparent plug 2 sidewalls of this buckle-type are provided with two symmetries with extend limiting section 4, the inboard is provided with boss, arranged outside that sealing gasket is installed that at least one lug boss 5 is arranged; The cartridge box body is provided with two clamping parts 6 and clamping part 7; After being encased in the transparent plug 2 of this buckle-type in the detection window 1, pin lug boss 5 rotations, make said extension limiting section 3 and said extension limiting section 4 lay respectively at said clamping part 6 and said clamping part 7 belows; Blocked with said clamping part 7 by said clamping part 6; Thereby lock the transparent plug 2 of said buckle-type, such structure more complicated, and make and install more loaded down with trivial details; Therefore; The applicant improves this, and the detection mouth structure after the improvement is as shown in Figure 2, and said detection mouth structure comprises detection window 1, transparent plug 8; Said transparent plug 8 is arranged on said detection window 1 place and said detection window 1 interference fit
Said detection window 1 is a counterbore, i.e. a little round tube hole and a big round tube hole, and said transparent plug 8 is provided with boss 9; Said boss 9 is positioned at the inboard on the said transparent plug 8, the aperture interference fit of said boss 9 and said counterbore, and the macropore that said transparent plug 8 is positioned at said counterbore is suitable with it; Compared with prior art, it has omitted sealing gasket, simultaneously; Simplified the structure of cartridge box body and transparent plug, and installing and locating through being filled in said detection window, said transparent plug gets final product, and has avoided rotating the trouble that transparent plug makes its aligned position; In addition; The arranged outside of said transparent plug 8 is fluted 10, is the thickness that is equivalent to reduce transparent plug 8 like this, makes that the effect that detects is clearer.
The novel cartridge field that is widely used in of this use.
