Description

The double-deck water wing of built-in gas filled device

Technical field

The utility model relates to a kind of double-deck water wing, relates in particular to a kind of double-deck water wing of built-in gas filled device.

Background technology

At present, people are when using double-deck water wing, it is cumbersome to double-deck water wing inflation that feel in the capital, blow very effort of inflation with mouth, if the valve of present especially double-deck water wing is not grasped certain skill, be difficult to blow into gas with mouth, if children and women inflate that is just more difficult for double-deck water wing with mouth, and use Floor Pump to carry in addition, very inconvenient, in order to address the aforementioned drawbacks, I had once invented a kind of water wing of built-in gas filled device, the patent No. 201020201757.4, this water wing can be inflated to water wing by built-in gas filled device, very laborsaving convenience, but this built-in gas filled device can only be given the water wing inflation of an air chamber, and inflate for two air chambers of double-deck inflation water wing simultaneously.

The utility model content

Problem to be solved in the utility model provides a kind of double-deck water wing that can give two gas filed built-in gas filled devices of air chambers while of double-deck water wing.

For addressing the above problem, the utility model adopts following design plan: a kind of double-deck water wing of built-in gas filled device, it comprises cylinder, handle, push rod, piston, O-ring seal, outer circle body, the internal layer circle body, annular gland, annular end cap, the annular bottom, soft sealing plug, big soft seal strip, valve, it is characterized in that: the center of described annular bottom end face is processed with circular hole, be processed with one with upper vent hole around center hole, the circular hole that big soft seal strip central protuberance is inserted annular bottom end face center is fixedly connected on the outside of annular bottom, annular bottom side be processed with annular bottom in the projection pipe that is communicated with, ventilation flue's one end is with the airtight connection of inner layer ring body wall, inner another cavity conducting of separating of ventilation flue with the internal layer circle body, on the protruding pipe of ventilation flue's other end socket annular bottom side, the airtight arbitrary position that is connected in ventilation flue and the projection pipe of one-way exhaust valve, described one-way exhaust valve comprises base, little soft seal strip, the center of base end face is processed with circular hole, center around the base end face also is processed with one with upper vent hole, in the middle of the little soft seal strip columnar projections is arranged, the circular hole internal fixation that columnar projections is inserted base end face center connects, and makes little soft seal strip be attached to the outside of base end face and covers air extractor vent.

Be that the end face of described one-way exhaust valve base is the shallow sphere of indent or the indent butt conical surface as further improvement of the utility model.

After adopting said structure, during inflation, push away before the piston, little soft seal strip in the big soft seal strip of annular bottom end face and the end cap lateral projections pipe on the one-way exhaust valve base is subjected to gaseous tension and opens simultaneously, and two air chambers in water wing are inflated simultaneously respectively, when piston is pulled back, big soft seal strip and little soft seal strip seal cooresponding air extractor vent simultaneously, gas in the cylinder can only pass through cylinder back-end, suck from the outside of circle body, can realize a built-in gas filled device so repeatedly simultaneously to two air chambers inflations, convenient and practical.

Description of drawings

Below in conjunction with the drawings and the specific embodiments the utility model is further described:

Fig. 1 is the structural representation of the double-deck water wing of the built-in gas filled device of the utility model.

Fig. 2 is the semi-sictional view enlarged drawing that the double-deck water wing of the built-in gas filled device of the utility model is fixed on the gas filled device on the airbag wall.

Fig. 3 is the amplification view of the double-deck water wing one-way exhaust valve of the built-in gas filled device of the utility model.

The specific embodiment

As Fig. 1, the double-deck water wing of a kind of built-in gas filled device shown in Figure 2, it comprises cylinder 1, handle 2, push rod 3, piston 4, O-ring seal 5, outer circle body 6, internal layer circle body 7, annular gland 8, annular end cap 9, annular bottom 10, soft sealing plug 11, big soft seal strip 12, valve 17, wherein be processed with circular hole at the center of annular bottom 10 end faces, be processed with one with upper vent hole around center hole, the circular hole internal fixation that big soft seal strip 12 central protuberance are inserted annular bottom 10 end face centers is connected the outside of annular bottom 10, and cover air extractor vent, annular bottom 10 sides are processed with and the annular bottom 10 interior projection pipes 13 that are communicated with, an end of ventilation flue 14 is socketed on the projection pipe 13 of annular bottom 10 sides, ventilation flue 14 the other end and airtight connection of internal layer circle body 7 walls, ventilation flue's 14 tube walls can directly 7 heat seals be connected with the internal layer circle body, also can adopt base that has protruding pipe of heat seal on the inner layer ring body wall earlier, the mode that the ventilation flue is socketed on the protruding pipe connects then, the airtight arbitrary position that is connected in ventilation flue 14 and the projection pipe 13 of one-way exhaust valve, corresponding each cavity is fixedly connected with a valve respectively on the circle body outer wall.

As shown in Figure 3, one-way exhaust valve comprises base 15, little soft seal strip 16, the center of base 15 end faces is processed with circular hole, center around base 15 end faces also is processed with one with upper vent hole, in the middle of the little soft seal strip 16 columnar projections is arranged, the circular hole internal fixation that columnar projections is inserted base 15 end face centers connects, make little soft seal strip be attached to the outside of base end face and cover air extractor vent, in order to make little soft seal strip 16 with better sealing between base 15 end faces, the end face of base 15 is the shallow sphere of indent or the indent butt conical surface, when the columnar projections of little soft seal strip centre was inserted the circular hole of base centre, little soft seal strip can utilize elasticity of self and end face to seal better like this.

During inflation, push away before the piston 4, the big soft seal strip 12 of annular bottom 10 end faces and the little soft seal strip 16 on the one-way exhaust valve base 15 in the end cap lateral projections pipe 13 are opened simultaneously, and two air chambers in water wing are inflated simultaneously respectively, when piston 4 is pulled back, big soft seal strip 12 and little soft seal strip 16 seal cooresponding air extractor vent simultaneously, gas in the cylinder 1 can only pass through cylindrical shell 1 rear end, suck from the outside of circle body, can realize that so repeatedly a built-in gas filled device is simultaneously to two air chambers inflations, when needing venting, be connected two valves on the air chamber and just can exit as long as open respectively, convenient and practical.

The double-deck water wing of the built-in gas filled device of the utility model is not limited to above-mentioned embodiment, and for example, circular hole also can be processed in the side of annular bottom, and the ventilation flue inserts circular hole by interference fit and is tightly connected; The projection pipe of annular bottom side also can be more than one; connect a plurality of cavitys respectively; be appreciated that every water wing that an interior gas filled device is given two or more cavity inflatable structures simultaneously that passes through, how conversion is all within the utility model protection domain regardless of connection mode.
