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, a kind of siphon with post detent mechanism 10 for present embodiment provides.Said siphon 10 comprises one first nozzle 11; Second nozzle 12 that is arranged on said first nozzle 11; A screw rod 13 that is arranged in second nozzle 12; A spring 14 that is arranged in said second nozzle 12, and a push rod 15 that is arranged in said second nozzle 12, and an elastic washer 16 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 14 is used for said push rod 15 is replaced to first nozzle 11 to locate said first, second nozzle 11, relative position between 12.Said screw rod 13 is used for said spring 14 is fixed on second nozzle 12 with push rod 15.
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 the double-screw bolt 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.The head diameter of the cross section of the screw thread of said double-screw bolt 114 and push rod 15 is suitable, and being beneficial to push rod 15 can be threaded into said double-screw bolt 114 in second nozzle 12 around this screw thread.
Please consult Fig. 5, Fig. 6 in the lump, the side near first siphon port 112 of said double-screw bolt 114 is provided with a through hole 115.The diameter of this through hole 115 is used for the part that ccontaining said push rod 14 exposes second nozzle more than or equal to the diameter of said push rod 15.This through hole 115 is arranged on the axis of one of them first siphon port 112.
Please consult Fig. 3 and Fig. 4 again; Said second nozzle 12 comprises one second body 121; A joint end 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 the joint end 122, and madial wall that is arranged on said joint end 122 and towards the gasket groove 126 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 joint end 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 joint end 122 is provided with the tapped through hole 124 in a L shaped cross section.This tapped through hole 124 the diameter of porch less than the diameter of remainder, thereby form said L shaped cross section.Said tapped through hole 124 is arranged on the axis of any one first siphon port 112, so that said first siphon port 112 is alignd with the axis of corresponding second siphon port 123 respectively.With first siphon port 112, said second siphon port 123 has identical effect with first siphon port 112.The notch of said gasket groove 126 is towards the double-screw bolt 114 of first nozzle 11, and less than the wall thickness of its width and double-screw bolt 114.
Said push rod 15 has axial step cross section, and the minor diameter of the diameter of an end and screw thread logical 124 is suitable, and the major diameter of the diameter of the other end and tapped through hole 124 is suitable, thereby forms a step push rod, is beneficial to be connected in the said L shaped tapped through hole 124.
The external diameter of said spring 14 is plugged in the said tapped through hole 124 to replace the large-diameter portion of said push rod 15.The length of this spring 14 is can replace said push rod 15 and to have certain decrement to be advisable.
The inside diameter of the diameter of said screw rod 13 and tapped through hole 124 is suitable; And be screwed onto in this tapped through hole 124; And be arranged on the opposite side with respect to push rod 15 of said spring 13, with the relative position of L shaped tapped through hole 124 fixing said push rods 15 with spring 14.
Said elastic washer 16 is contained in the said gasket groove 126, and the free end face interference fit of the free end face of this elastic washer 16 and double-screw bolt 114.Because when ball 14 matches with pit 125; Be difficult to guarantee that the double-screw bolt 114 and the internal thread of joint end 122 just in time screw tight; This will produce two kinds of situation, and a kind of is that double-screw bolt 114 screws tight with joint end 122, and ball 14 does not but cooperate with pit 125; Another kind is that double-screw bolt 114 does not also screw tight with joint end 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 double-screw bolt 114 and joint end 122, eliminates above two kinds of flaws that possibly occur.
Owing to have spring 14 and push rod 15 on said second nozzle 12; And first detent mechanism that constitutes of through hole 115 on the nozzle 11; When said first nozzle 11 and second nozzle 12 are assembled; The part that said push rod 15 exposes joint end 122 madial walls is placed in this through hole 115 fully, four first siphon port 112 of first nozzle 11 and four siphon port 123 of second nozzle 12 is aligned, simultaneously the relative position of fixing said first, second nozzle 11,12.Thereby 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 16 can guarantee that said ball 14 matches with pit 125, can guarantee that also said double-screw bolt 114 screws tight with joint end 122 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.
