Description

Balanced type fast aeration structure

Technical field

The utility model is about one inflation equipment, refers to a kind of balanced type fast aeration structure especially.

Background technology

What existing gas cylinder had low pressure also to have high pressure, low pressure be all the non-return structure that withstands of the single spring of application, also being identical being inflated end, so all will very firmly go to top could inflate both ways, holding air pressure high if be inflated, can do not fill completely, if high pressure person, general manpower cannot be inflated, in order to provide the article of more realistic demand by breakdown, inventor researches and develops, to solve the force problem that existing use easily produces.

Utility model content

Main purpose of the present utility model is to provide a kind of balanced type fast aeration structure, no matter that gas very successfully can be filled with and is inflated room by how many atmospheric pressures by gas in gas filling bottle, startup force is therebetween very little, and changing large pressure in the past need by the using state of instrument.

For reaching above-mentioned object, the utility model provides a kind of balanced type fast aeration structure, its have in a gas filling bottle end an inflation element be inflated one of room port in one and be inflated element, inflation element has touch a slide bar in a plenum chamber, a ring edge is had outside slide bar, an elastic component is had between the end in ring edge and plenum chamber, drop-stopping ring and an outer drop-stopping ring in the inner peripheral surface location one of plenum chamber, the both ends of the surface of slide bar offer a kerve and an inverted draw cut respectively inwardly, in kerve with inverted draw cut, the end, pushes up to bore a hole with a bottom hole and one respectively and passes to plenum chamber inner peripheral surface mutually, during unaerated, top perforation is positioned at the foreign side of outer drop-stopping ring, when moving in slide bar, bored a hole in top and move to the interior side of outer drop-stopping ring, conducting gas flows out, be inflated element to contain a valve groove and insert by slide bar, be communicated with an air flue in valve groove, in air flue, the end, is provided with at least one horizontal perforation to being inflated room, each horizontal perforation be inflated room interfascicular fasciculus and have a drop-stopping ring, back down drop-stopping ring when gas flow is flowed out by horizontal perforation.

In an embodiment of the present utility model, being wherein inflated element is be fixed in the main body being inflated room mouth, forms a scrobicular ring to locate this drop-stopping ring in main body the inner.

In an embodiment of the present utility model, wherein elastic component is a spring.

Balanced type fast aeration structure of the present utility model, during use, starts force little, has good usability and convenience.

Technology, means and the effect that further can understand the utility model for making your juror and take for reaching predetermined object, hereby for a better feasible embodiment, and coordinate graphic being described in detail as follows, believe the purpose of this utility model, feature & benefits, go deep into and concrete understanding when one can be obtained thus.

Detailed description of the invention

As shown in Figures 1 to 7, for a kind of balanced type fast aeration of the utility model structure, have in gas filling bottle 1 end an inflation element 10 be inflated room 2 end (as the room of being inflated is implemented on a peashooter part by Fig. 5 in one, but not as limit) mouth one be inflated element 20, inflation element 10 has touch a slide bar 12 in a plenum chamber 11, there are a ring edge 125 and a clasp 14(clasp for preventing from moving excessively outside slide bar 12 and design), the body 100 of inflation element 10 can containing a pressure regulator 3(as Fig. 1, separate case application), one end interlocking of body 100 is as one of taper hollow pullover 103, body and pullover 103 overlaps with an apical ring ditch 101 therebetween an apical ring circle 102, a ring set 19 is had in pullover 103, the interior of ring set 19 is the air chamber of channel-style and allows slide bar 12 pass, the external lock of ring set 19 is connected to the port of body 100, and a middle ring 192 is had with middle circular groove 191 cover in appearance, have between the end in ring edge 125 and plenum chamber 11 in an elastic component 13(figure is spring), the inner peripheral surface of plenum chamber 11 once on groove 15 and a groove 16 locate drop-stopping ring 17 and an outer drop-stopping ring 18 in one, the both ends of the surface of slide bar 12 offer kerve 121 and an inverted draw cut 122 respectively inwardly, in kerve 121 with inverted draw cut 122, the end, pushes up perforation 124 with a bottom hole 123 and one respectively and passes to plenum chamber 11 inner peripheral surface mutually, the foreign side that perforation 124 is positioned at outer drop-stopping ring 18 is pushed up during unaerated, when inflating, toward interior top (slide bar 11), when moving in slide bar 11, top perforation 124 is made to move to the interior side of outer drop-stopping ring 18, the gas of conducting kerve 121 arrives plenum chamber inner peripheral surface 11 through bottom hole 123, flow out outwardly after flowing into inverted draw cut 122 by top perforation 124, as Fig. 2 A and Fig. 6, being inflated element 20 allows slide bar 12 insert containing a valve groove 21, an air flue 22 is communicated with in valve groove 21, in air flue 22, the end, is provided with at least one horizontal perforation 23 to being inflated room 2, each horizontal perforation 23 be inflated room 2 interfascicular fasciculus and have a drop-stopping ring 24, back down drop-stopping ring 24 when gas flow is flowed out by horizontal perforation 23.Being inflated element 20 is be fixed in the main body 25 being inflated 2 mouthfuls, room, forms a scrobicular ring 26 to locate this drop-stopping ring 24 in main body 25 the inner.A ring is all provided with to strengthen stopping leak effectiveness in the inner circumferential of the periphery of main body 25 and valve groove 21; Be inflated room 2 other end only to illustrate, no longer illustrate with this case is irrelevant.

Structure in sum, the utility model uses the equalizing pressure of particular design in gas filling bottle part, the pressure of air pressure and elastic component 13 props up, when the outlet side that slide bar 12 is formed that exerts a force, as long as overcome the pressure of elastic component, naturally because the gas in gas filling bottle 1 flows out to plenum chamber 11 inner peripheral surface by the bottom of plenum chamber 11 through kerve 121 to the bottom hole 123 of slide bar 12, gas flows outward along the gap between slide bar 12 appearance and plenum chamber 11, slide bar 12 is flowed out after flowing into inverted draw cut 122 by top perforation 124 soon, horizontal perforation 23 place entering air flue 22 to bottom back down drop-stopping ring 24 flow out to be inflated room 2(as Fig. 7 or Fig. 4) in, when not inflating, when being inflated by what be inflated room 2 the inflation element 10 that element 20 unplugs gas filling bottle end 1, the position (as Fig. 6 or Fig. 3) of just automatically with its elastic force, slide bar 12 being rebounded closed by elastic component 13, just no longer give vent to anger, apply the two-way closed effectiveness of a pair drop-stopping ring exactly, complete balance delicate between gas turnover gas, overall structure allows people the most easily understand and implements, so good usability and convenience can be provided, be one completely from existing different mechanism.

The above is the detailed description of the utility model preferred embodiment and graphic, not be used for limiting this creation, all scopes of the present utility model should be as the criterion with following the scope of the claims, the embodiment of the spirit change similar with it of all the scope of the claims and approximate construction, all should be contained among the utility model.
