The specific embodiment
Below be further elaborated based on the specific embodiment of accompanying drawing to the utility model.Should be appreciated that specific embodiment described herein as just embodiment, and be not used in the protection domain that limits the utility model.
See also Fig. 3 and Fig. 4, be a kind of combined nozzle 10 that is used to have detent mechanism that present embodiment provided.Said nozzle 10 comprises one first nozzle 11; Second nozzle 12 that is arranged on said first nozzle 11; A spring 13 that is arranged in second nozzle 12; An and ball 14 that is arranged in said first nozzle 11, and elastic washer 15 that is arranged between said first nozzle 11 and second nozzle 12.In the present embodiment, said first nozzle 11 is connected with snap fit with second nozzle 12.Said spring 13 is used for said ball 14 is replaced to first nozzle 11 to locate said first, second nozzle 11, relative position between 12.
Said first nozzle 11 comprises one first body 111; Four first siphon port 112 that are arranged on this first body 111; 113, one of an internal thread hole of jet end that are used to connect air drifting dust rifle (figure do not show) that are arranged on these first body, 111 1 ends is arranged on first clip-connecting rod 114 that is used to connect second nozzle 12 of the other end of said this first body 111.Said first siphon port 112 is opened on the sidewall of said first body 111, is evenly distributed with four first siphon port 112 in the present embodiment.What can expect is that a plurality of these first siphon port 112 arbitrarily can be set as required.The shape of this first siphon port 112 can be made as triangle, oval hole shape, circle, square or other various geometries on demand, and size also is able to suitably change, and looks demand fully and changes.When said first nozzle, 11 jet flows go out swiftly flowing compressed air; Air storage capacity with the flow consumed cabin air compressor of 150 liters of per minutes; When these first nozzle, 11 jet flows go out the air of low-voltage high speed; First siphon port 112 around this first nozzle 11 forms vacuum states, sinks the air of first siphon port, 112 external high pressures, and a large amount of air flow into compressed air with high speed jet in first nozzle, 11 internal mix jet flows by first siphon port 112; Thereby increase the flow of air-flow, and then increase dust removing effects.
Please consult Fig. 5, Fig. 6 in the lump, the side near first siphon port 112 of said first clip-connecting rod 114 is provided with four through holes 116.The diameter of this through hole 116 is less than or equal to the diameter of said ball 14, is used for the part that ccontaining said ball exposes second nozzle.At the diameter of this through hole 116 during less than the diameter of said ball 14, the part of must said ball 14 exposing second nozzle 12 is placed in this through hole 116 fully and is advisable.These four through holes 116 are separately positioned on the axis of four first siphon port 112, so that said first siphon port 112 is alignd with the axis of corresponding second siphon port 123 respectively.Said first clip-connecting rod 114 comprises that also four are arranged on this first clip-connecting rod, 114 outer surfaces, and the gathering sill 115 that is connected with said four through holes 116 respectively.
Please consult Fig. 3 and Fig. 4 again; Said second nozzle 12 comprises one second body 121; Second clip-connecting rod 122 that is arranged on these second body, 121 1 sides; At least one is arranged on second siphon port 123 between said second body 121 and second clip-connecting rod 122, and madial wall that is arranged on said second clip-connecting rod 122 and towards the gasket groove 125 of said second body 121.In order to enlarge the dedusting area of this nozzle 10, the diameter of said second body 121 is greater than the diameter of said second clip-connecting rod 122, thereby makes second siphon port 123 be arranged on the inclined-plane.In order to make each first siphon port 112 corresponding with second siphon port 123, the quantity of this second siphon port 123 equates with the quantity of first siphon port 112.The free end side of said second clip-connecting rod 122 is provided with four counterbores 124.The diameter of the porch of these four counterbores 124 is less than the diameter of said ball 14, with these ball 14 interference fit.These four counterbores 124 are except that the diameter of porch, and the diameter of the aperture of remainder and ball 14 is suitable.Said four counterbores 124 are separately positioned on the axis of four second siphon port 123.With first siphon port 112, said second siphon port 123 has identical effect with first siphon port 112.The notch of said gasket groove 125 is towards first clip-connecting rod 114 of first nozzle 11, and less than the wall thickness of its width and first clip-connecting rod 114.
The diameter of the porch of the external diameter of said spring 13 and counterbore 124 is suitable, is beneficial to this spring 13 is inserted in this counterbore 124.The length of this spring 13 is can replace said ball 14 and to have certain decrement to be advisable.
The inside diameter of the diameter of said ball 14 and counterbore 124 is suitable.Because ball 14 is interference fit with the porch of counterbore 124, when assembling, need this ball 14 is pressed into by external force in the said counterbore 124.Simultaneously,, after this ball 14 is pressed in the counterbore 124, can from this counterbore 124, not drop out, can not replaced out simultaneously yet by said spring 13 because the porch of ball 14 and counterbore 124 is interference fit.
Said elastic washer 15 is contained in the said gasket groove 126, and the free end face interference fit of the free end face of this elastic washer 15 and first clip-connecting rod 114.Because when ball 14 matches with pit 125; Be difficult to guarantee that the internal thread of first clip-connecting rod 114 and second clip-connecting rod 122 just in time screws tight; This will produce two kinds of situation, and a kind of is that first clip-connecting rod 114 screws tight with second clip-connecting rod 122, and ball 14 does not but cooperate with pit 125; Another kind is that first clip-connecting rod 114 does not also screw tight with second clip-connecting rod 122, and ball 14 matches with pit 125.Therefore the effect that adds this elastic washer 15 just is to increase the surplus that screws tight of first clip-connecting rod 114 and second clip-connecting rod 122, eliminates above two kinds of flaws that possibly occur.
Owing to have four springs 13 and four balls 14 on said second nozzle 12; And first detent mechanism that constitutes of four through holes 116 on the nozzle 11; When said first nozzle 11 and second nozzle 12 are assembled; The part that said ball 14 exposes second clip-connecting rod, 122 madial walls is placed in this through hole 116 fully; Four first siphon port 112 of first nozzle 11 and four siphon port 123 of second nozzle 12 are aligned, the relative position of fixing said first, second nozzle 11,12 simultaneously, thus can avoid in first, second siphon port 112, form sinuous flow in institute's inhaled air stream between 123; And the phase mutual interference, and then avoid reducing arrival by the air-flow of dedusting face.When the effect of adding elastic washer 15 can guarantee that said ball 14 matches with pit 125, can guarantee that also said first clip-connecting rod 114 and second clip-connecting rod 122 screw tight each other.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Interior any modification of doing of all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included in the utility model protection domain in.
