Embodiment
Now lift following examples and by reference to the accompanying drawings structure of the present invention and effect be elaborated.
Double-purpose wind fairing head of the present invention can directly be made on a hand-held inflator, or is connected to a pump or the air supply source of other form by a flexible pipe.
As shown in Figure 1 and Figure 2, American mouth of the present invention and French mouth double-purpose wind fairing head include:
One housing 10, has an axis hole 11, and housing 10 sides, toward extension one end portion 12, have a through hole 13 in the middle of end 12, are communicated with axis hole 11.The end 12 of the present embodiment can be connected with an air supply hose (not shown); Or be made of one with hand-held inflator.If be made of one, end 12 forms the running shaft of housing 10.
One rotating component 20, there is the body portion 21 of a stock shape, body portion 21 two ends respectively have the head 22 that an external diameter is larger, 23, rotating component 20 is to be contained in the axis hole 11 of housing 10 with its body portion 21, its two head 22, 23 lay respectively at outside housing 10, rotating component 20 can be rotated in the axis hole of housing 10 11 and can not deviate from, rotating component 20 is by two heads 22, 23 exterior edge faces are toward the interior bolt apertures 221 that is respectively provided with, 231, the a wherein bolt apertures 221 French mouth (as shown in Figure 3) that can be spirally connected, another bolt apertures 231 American mouth (as shown in Figure 4) that can be spirally connected, in the middle of the body portion 21 of rotating component 20, be provided with a containing space 24, containing space 24 is with two through hole 222, 232 respectively with two bolt apertures 221, 231 are communicated with, rotating component body portion 21 outer wall are concaved with an annular groove 211, annular groove 211 forms an annular air channel 25 in the axis hole 11 of housing 10, annular air channel 25 is communicated with the through hole 13 of the end 12 of housing 10 again, rotating component body portion 21 establishes a perforation 212 in annular groove 211 positions, be communicated with annular air channel 25 and containing space 24.
Two O shape seal rings 30, are located at rotating component 20 body portions 21 and lay respectively at the both sides of annular groove 211, form the leak-stopping assembly of annular air channel 25 both sides.The present embodiment is established two grooves 213 in body portion 21, for sheathed two O shape seal rings 30.
One spheroid 40, is contained in containing space 24.Wherein the internal face of containing space 24 is respectively forming a hemisphere or approximate hemispheric recess 241,242 with the position that is communicated with of two through hole 222,232, the radius of spheroid 40 is less than the radius of recess 241,242, is greater than the radius of connecting through hole 222,232.
A wherein head or two heads of rotating component 20 are to arrange respectively with rotating component, more affixed integral.The present embodiment is to adopt the head 23 of American mouth bolt apertures 231 positions to separate manufacture with body portion 21, and body portion establishes 21 outer ends a spiro union portion 214, and head 23 is and covers shape, internal face establish spiro union portion 232 with the spiro union portion 214 of body portion 21 be spirally connected lock integral.Certainly can with adhesive, fix again.Except being spirally connected, also can adopt interlocking, gluing etc. mode to link into an integrated entity.Head 23 central authorities are provided with a screw 233.
The body portion 21 of rotating component 20 with the fixed connecting end of head 23 from the outer pothole 215 that is concaved with toward in, in pothole 215, be embedded an abaculus 26, and form aforesaid containing space 24 between abaculus 26 and pothole 215 inner end wall.Two 241,242 of recesses lay respectively on pothole 215 inner end wall and abaculus 26.As shown in Figure 1, abaculus 26 is provided with a hemispherical depression and forms aforesaid recess 242, and outside is provided with a groove 261, and centre is provided with a perforation, and this perforation forms aforesaid through hole 232, and abaculus 26 is provided with breach 262 in bottom.One O shape encircles 27, is enclosed within the groove 261 of abaculus 26, to form airtight with pothole 215 internal faces.One thimble piece 28, is located at and in pothole 215, is positioned at abaculus 26 outsides.One packing ring 29, is located at thimble piece 28 outsides.Thimble piece 28, packing ring 29 and the common joint that forms American mouth of head 23.Bolt apertures 221 is interior is provided with an O shape ring 31, leak-stopping while connecting for French mouth near going out muzzle end.
As shown in Figure 3, when bolt apertures 221 is spirally connected a French mouth (in figure shown in imaginary line), the air being entered by through hole 13, through annular air channel 25 and perforation 212, enter containing space 24, originally air can be released by bolt apertures 231, but the suction that air-flow causes can drive rapidly spheroid 40 to seal the through hole 232 of recess 242 sides, makes to be airtight, and the high-pressure air in containing space 24 enters bolt apertures 221 French mouth is inflated.
As shown in Figure 4, when bolt apertures 231 is spirally connected an American mouth (in figure shown in imaginary line), if there is air in object to be inflatable, the air-flow releasing just can promote spheroid 40 self-closeds and live through hole 222, otherwise, as aforementioned, the air that the initial stage is entered by through hole 13 can be released by through hole 222, and the suction that air-flow causes can drive spheroid 40 to seal through hole 222, make to be airtight, enter continuously the air of containing space 24 to American valve inflation.
Feature of the present invention is structure simplifying very, therefore volume is also very small and exquisite, in operation, do not take up space, again with screw thread locking mode, can not wrong when docking screws togather valve cock, even can rotate the be spirally connected sensation of valve cock of rotating component with finger under dim light, judge mistake, once and be spirally connected upper just very firmly, without the anxiety coming off, very convenient in use.
