Abstract

The invention belongs to the field of color selectors and particularly relates to a gas-blowing system of a color selector. The gas-blowing system of the color selector comprises a nozzle main body, wherein a pore which is a stepped hole is formed in the nozzle main body and comprises a large aperture section and a middle aperture section which are sequentially arranged, the aperture of the middle aperture section is matched with the diameter of a gas pipe, and the middle aperture section is communicated with a groove which is formed on one side face of the nozzle main body; a snap ring which is arranged on the gas pipe in a sleeving manner is placed in the large aperture section, a pressure plate is arranged on the nozzle main body to prevent the snap ring from falling, and a through hole, through which a gas supply pipe passes through is formed on the pressure plate. The gas pipe is fixed by virtue of the snap spring. During installation, the snap spring is directly placed in the large aperture section of the pore and the snap spring is limited in the large aperture section by virtue of the pressure plate, and the gas pipe inserted is locked by virtue of the snap spring. The gas-blowing system of the color selector is simple in structure and convenient to install. More importantly, the snap spring is very low in cost relative to an inflating valve.

Description

Color selector scavenger system

Technical field

The invention belongs to field of color sorter, particularly a kind of color selector scavenger system.

Background technology

Scavenger system is the requisite parts of color selector, material defective can be produced by boasting the object reaching separation by scavenger system.Existing a kind of scavenger system structure as Figure 1-5, Fig. 1 is the perspective view of scavenger system in prior art, it comprises blow gun body 1 and is fixedly mounted on the valve cock 2 on blow gun body 1, Fig. 3 is the lateral side view of blow gun body 1, here with valve cock 2, that relative side of side is installed in the rear side said and Fig. 1, blow gun body 1 is provided with the pore 3 of height interlaced arrangement, one end of pore 3 is provided with internal thread 5 and forms with valve cock 2 and coordinate, the other end communication groove 4 of pore 3.

When using, need valve cock 2 to be fixedly installed on blow gun body 1, after treating that all valve cocks 2 are all fixed on blow gun body 1, then blow gun body 1 and other parts are fixed, finally tracheae is directly planted in valve cock 2.Like this, air-flow is by groove 4, and---pore 3---valve cock 2---tracheae forms path.In this structure, although tracheae can be inserted in valve cock 2 very easily, because valve cock 2 and blow gun body 1 are threaded engagement and the One's name is legion of valve cock 2, as shown in Figure 2, the installation of valve cock 2 taking time and effort very; In addition, because valve cock 2 has outer-hexagonal projection, so just limit the layout density of each pore; Meanwhile, the valve cock 2 of numerous quantity causes the increase of installation cost.

Summary of the invention

The object of the present invention is to provide a kind of color selector scavenger system, convenience fixes tracheae and cost is low.

For realizing above object, the technical solution used in the present invention is: a kind of color selector scavenger system, comprise blow gun body, blow gun body is provided with pore, described pore is shoulder hole, it comprises large aperture section, the mesoporous section of arranging successively, and the aperture of mesoporous section and the diameter of tracheae match, and mesoporous section is connected with the groove that a side of blow gun body is offered; Being placed with the jump ring for being set on tracheae in the section of large aperture, blow gun body being provided with pressing plate and preventing jump ring from dropping, pressing plate offering the through hole that air supply pipe passes through.

Compared with prior art, there is following technique effect in the present invention: realizes fixing tracheae by jump ring, when mounted, jump ring is placed directly in the large aperture section of pore, then is limited in the section of large aperture by pressing plate by jump ring, is locked when tracheae inserts by jump ring, this structure is simple, easy for installation, the more important thing is, jump ring is very low relative to valve cock cost.

Detailed description of the invention

Below in conjunction with Fig. 6 to Figure 10, the present invention is described in further detail.

Consult Fig. 6, Fig. 7, a kind of color selector scavenger system, comprise blow gun body 10, blow gun body 10 is provided with pore 11, described pore 11 is shoulder hole, it comprises large aperture section 111, the mesoporous section 112 of arranging successively, and the aperture of mesoporous section 112 and the diameter of tracheae 40 match, and mesoporous section 112 is connected with the groove 12 that a side of blow gun body 10 is offered; Being placed with the jump ring 20 for being set on tracheae 40 in large aperture section 111, blow gun body 10 being provided with pressing plate 30 and preventing jump ring 20 from dropping, pressing plate 30 offering the through hole 31 that air supply pipe 40 passes through.Realize tracheae 40 by jump ring 20 fixing, bring many benefits: one, when avoiding assembling valve cock, valve cock is screwed to the trouble in screwed hole; Its two, significantly reduce costs; Its three, it is more that the pore 11 on blow gun body 10 can be arranged, that is, when needing to specify the pore 11 of number, can reduce the volume of blow gun body 10, being arranged in color selector more easily.

In use, only need the large aperture section 111 jump ring 20 being put into successively each pore 11, then pressing plate 30 is fixed on blow gun body 10, finally tracheae 40 is inserted from through hole 31.Under the effect of external force, tracheae 40 is when through hole 31 inserts, deformation can be there is and allow that tracheae 40 inserts in jump ring 20, can stop when the end of tracheae 40 is inserted to mesoporous section 112 applying external force, now jump ring 20 is set on the periphery wall of tracheae 40, because jump ring 20 is limited in large aperture section 111 by the ladder in pore 11 and pressing plate 30, therefore tracheae 40 is also just fixed.

Consult Fig. 8, Fig. 9, as preferred version of the present invention, described pore 11 also comprises small-bore section 113, and large, medium and small aperture section 111,112,113 is arranged successively, and mesoporous section 112 is connected with the groove 12 that a side of blow gun body 10 is offered through small-bore section 113.After small-bore section 113 is set, during one end of tracheae 40 can be resisted against, the step place that formed of small-bore section 112,113, increase sealing effectiveness further.

The structure of blow gun body 10 has a variety of, in the present embodiment, described blow gun body 10 is in rectangular-shaped, one side of blow gun body 10 offers groove 12, another side parallel is with it fixedly installed described pressing plate 30, pore 11 is communicated with these two parallel sides and the axle core of pore 11 and this two lateral vertical.

Consult Figure 10, preferably, the body 21 of described jump ring 20 is in annulus sheet, and the internal diameter of jump ring body 21 is less than the caliber of tracheae 40, large aperture section 111 matches along the size of shaft core direction and the thickness of jump ring body 21, and such jump ring 20 would not rock in large aperture section 111.The periphery of described jump ring body 21 offers the opening of the first breach 22, first breach 22 outside annulus; The inner circumferential of jump ring body 21 offers the second breach, the opening of the second breach 23 is inside annulus, first and second breach 22,23 all circumferentially interval is evenly arranged and the first breach 22 and the second breach 23 interlaced arrangement, also, all in dentation from the periphery or inner circumferential of jump ring 10.By first and second breach 22,23 that jump ring body 21 is arranged, make the deformability of jump ring 20 itself moderate, can insert and reliably hold tracheae 40 tightly by air supply pipe 40 very easily.
