Abstract

A clamping combination siphon head nozzle comprises a first nozzle, a second nozzle and a clamping elastic sheet. The first nozzle comprises a first clamping column. The first clamping column is provided at least one clamping pit which is matched with the clamping elastic sheet and is provided with four walls. The second nozzle comprises a second clamping end and at least one elastic sheet fixing groove which is arranged on the inner side wall of the second clamping end and is used to fix the clamping elastic sheet. The elastic sheet is meshed with the clamping pit to fix relative positions of the first nozzle and the second nozzle. Due to the fact that the clamping pit and the clamping elastic sheet are arranged, at assembling time, the clamping portion of the clamping elastic sheet can be arranged in the clamping pit in a clamping mode only after the first clamping column of the first nozzle is inserted into the second clamping end of the second nozzle, thereby fixing the relative positions of the first nozzle and the second nozzle. Compared with the prior art, the first nozzle or the second nozzle is screwed without need of being rotated, thereby saving assembling time and reducing labor cost.

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 to Fig. 6, be a kind of plug-in combination siphon nozzle 10 that present embodiment provided.Said nozzle 10 comprises that 11, one at one first nozzle is arranged at second nozzle 12 on said first nozzle 11, and a clamping shell fragment 13 that is arranged in said second nozzle 12.In the present embodiment, said first nozzle 11 is connected with snap fit with second nozzle 12.Said clamping shell fragment 13 is used for fixing the relative position of said first,

second nozzle

11,12 between axially.

Said first nozzle 11 comprises one first body 111; First siphon port 112 that is 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.Said first clip-connecting rod 114 is provided with at least one clamping hole 115, is used for matching with said clamping shell fragment 13, with said first,

second nozzle

11,12 of clamping.This clamping hole 115 be a kind of around the square groove of tool wall, with axially or radially mobile of restriction clamping shell fragment 13.Said first siphon port 112 has a upwind leg 116 near a side of second nozzle 12, and the normal direction of this upwind leg 116 and outside air flow into the in the opposite direction of first nozzle 11.

Said second nozzle 12 comprises that 121, one of one second bodies are arranged on second joint end 122 of these second body, 121 1 sides, and at least one is arranged on second siphon port 123 between said second body 121 and second joint end 122.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 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.With first siphon port 112, said second siphon port 123 has identical effect with first siphon port 112.The madial wall of said second joint end 122 is provided with a shell fragment holddown groove 124, is used for ccontaining said clamping shell fragment 13, its length greater than with the length of this clamping shell fragment 13 when not compressing.Said second siphon port 123 has a limit 125 with the wind near a side of first siphon port 112, and normal direction on limit 125 is identical with the direction that outside air flows into first nozzle 11 with the wind for this, and this with the wind the length D2 on limit 125 equate with the length D1 of upwind leg 116.Because first siphon port 112 is near the upwind leg 116 of second siphon port, 123 1 sides and second siphon port 123 equal in length near the limit with the wind 125 of first siphon port, 112 1 sides; Make at this upwind leg 116 and the air-flow width that gets on the limit 125 with the wind consistent; Thereby can reduce from of the interference of first siphon port, 112 inhaled airs stream, and then can avoid reducing arrival by the air-flow of dedusting face to forming from second siphon port, 123 inhaled airs stream.

Said clamping shell fragment 13 comprises 131, one Access Divisions 132 that are connected with this stiff end 131 of a stiff end, and an elongated end 133.Said stiff end 131 is fixed on the side towards inlet of said shell fragment holddown groove 124, is beneficial to when first clip-connecting rod 114 during from this inlet insertion second joint end 122, and said clamping shell fragment 13 is fixed, and moves to elongated end 133.Said stiff end 131 and elongated end 133 all can be arc, so that it has elasticity.Said Access Division 132 cooperates with clamping hole 115 to be replaced, and is limited in wherein by clamping hole 115, so these Access Division 152 best axis perpendicular to said first clip-connecting rod 114.Said elongated end 133 abuts against in the shell fragment holddown groove 124, when first clip-connecting rod 114 when this inlet inserts second joint end 122, just, move to guide said Access Division 132 along the basal sliding of shell fragment holddown groove 124.

Owing to have the clamping hole 115 of said first nozzle 11; And be arranged on the clamping shell fragment 13 on second nozzle 12; When assembling; As long as first clip-connecting rod 114 of first nozzle 11 is inserted second joint end 122 of second nozzle 12, the Access Division 132 of said clamping shell fragment 13 just can be fastened in the said clamping hole 115, and clamping shell fragment 13 moving axially or radially can be limited in clamping hole 115.Thereby can fix the relative position of said first, second nozzle.Compared with prior art, need not rotate first or second nozzle with this first, second nozzle that is spirally connected, thereby practice thrift built-up time, reduce cost of labor.

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.
