Description

A kind of pump that places air bag inside

Technical field

The utility model relates to a kind of pump, relates in particular to a kind of pump that places air bag inside.

Background technique

At present, the employed pump of known inflatable product all is the outside that places air bag, pump charges into air bag inside by the valve of air bag with gas, as inflate water wing, the inflation swim suit, inflatable air cushion, air dome, Air-filled bathtub, and various inflatable toys or the like, the valve of these inflatable product air bags is all narrower and small, be used for to the valve of the pump of airbag aeration also very narrow and small equally, in order to allow the air bag fast aeration, need bigger pressure gas could be charged into air bag fast, therefore, everybody can feel to require great effort very much when airbag aeration is given in the outside with this common pump, and its pump also will carry very trouble separately.

The model utility content

The technical problems to be solved in the utility model provides a kind of air bag inside that can be built in and not only had been convenient for carrying but also had inflated the labour-saving pump.

For addressing the above problem, the utility model adopts following design proposal: a kind of pump that places air bag inside, it comprise the almost coaxial heart cylinder, place piston in the cylinder, be socketed in O-ring seal, inflator handle on the piston, be used to connect the push rod of handle and piston; It also comprises the soft sealing plug that is socketed on the handle projection pipe and cylinder is fixed on ring-type gland on the airbag wall, the top end mask of described cylinder has extended projection pipe, this projection pipe and the cylinder almost coaxial heart but diameter are less than cylinder, the end face of described ring-type gland has and also has extended projection pipe, this projection pipe and the ring-type gland almost coaxial heart but diameter are less than gland, the cylinder projection is managed corresponding with gland projection pipe sidewall surfaces and is formed a fixed connection, and airbag wall places between gland and the cylinder; The general shape of soft sealing plug is that inverted frustum is tubular, its bottom external diameter is slightly less than the internal diameter of cylinder projection pipe, the top external diameter is slightly larger than the internal diameter of cylinder projection pipe, this soft sealing plug is socketed in the root of handle projection bar, subordinate soft on time sealing plug is inserted the inner chamber of cylinder projection pipe and finish sealing, guarantee cylinder interior and extraneous airtight isolation; Push rod one end is with the adhering junction of cylinder inner carrier, and the other end is socketed in the front end adhering junction of handle projection bar; Center at another Closed End of cylinder has a circular hole, also has at least two vents around its end face center; Described soft diaphragm seal center is a columnar projections, and the slightly larger in diameter of columnar projections is in the circular hole at end face center, and the columnar projections of soft diaphragm seal is plugged in the center hole of cylinder front-end face, makes soft diaphragm seal be attached to the outside of cylinder front-end face.

Handle can also be another with the connection of soft sealing plug, push rod, and the front end of handle projection bar is processed with annular boss, and soft sealing plug is enclosed within on the protruding bar, is connected between boss and the handle, and it is bonding that push rod inserts the inner circular aperture of protruding bar.

As further improvement of the utility model be, the other end of cylinder closure is the shallow sphere of indent or the butt conical surface, the end face indent can make soft diaphragm seal be fixed on behind the cylinder front end outside because the elasticity of self is close to the outer surface that is attached to end face, can guarantee the better sealing at itself and end face like this.

After adopting said structure, pushing away when inflation soft diaphragm seal before piston is subjected in the cylinder gas pressure and opens, soft diaphragm seal falls the vent of closed cylinder front-end face after rise during the piston post-tensioning, because the bottom of inflator cylinder does not have narrow valve, so gas can flow through the front end vent during inflation under less air pressure, it is very laborsaving that inflation can be felt, and inflator is connected by airtight connection set, and air bag inside is also very convenient carries.
