Embodiment
For the effect that describes structure of the present invention in detail and reached, now lift a preferred embodiment and conjunction with figs. and be described as follows.
As Fig. 2~shown in Figure 6, the valve joint of the embodiment of the invention includes:
One housing 40, it has a gas-entered passageway 41, be communicated with the flow channel (not shown) that goes out of inflator, present embodiment is provided with a connection-peg 42 in gas-entered passageway 41 outer ends, peg graft for a flexible pipe (not shown), being spirally connected with a stopper 43 is locked together on the default screw thread 44 of housing 40 again, and this kind pattern can have the inflator use of inflated hose for floor model pump (FloorPump) etc.Housing 40 also can be directly connected on the pump, need not to connect by flexible pipe, and for example hand-held pump (Hand Pump) or mini inflating pump pumps such as (Mini Pump) use.
It was located in the housing 40 to chamber 46 in one minute, was communicated with gas-entered passageway 41.
Two connect nozzle assembly 50,60, are located on the housing 40, and each is communicated with to chamber 46 with branch with a runner 52,62, and its connection place respectively forms a pore 53,63.
One switch piece 90, be hubbed on branch in chamber 46 with the centre, respectively form a swing arm 91,92 in the pivot both sides, two swing arms 91,92 can pivot 93 be done for the axle center and to be swung up and down, as the seesaw shape, and with two swing arms 91,92 one of them closes corresponding two and connects nozzle assembly 50,60 pore 53,63 wherein.In order to closed flow 52 or runner 62.In the present embodiment, two swing arms 91,92 of switch piece 90 have an angle not on same plane between the two, and as shown in Figure 4, when a swing arm 92 closed a pore 63,91 up perks of another swing arm made another pore 53 open (as shown in Figure 6).
Present embodiment is provided with a cross groove 401 on housing 40, and two longitudinal flutings 402,403 are communicated with cross groove 401.In cross groove 401, be embedded the whole body portion member 47,42 of connection-pegs are formed at all member 47 1 ends of body, and gas-entered passageway 41 is formed in the body portion member 47 and leads interspersed joint 42, divides also to be formed at body portion member 47 to chamber 46, and be communicated with gas-entered passageway 41, pivot 93 is located at branch in chamber 46.
Two connect nozzle assembly 50,60 is respectively an American mouth (Schrader valve) 50 and one French mouth (Prestavalve) 60, and American mouth 50 includes: a resilient sleeve 51, a bounding means 54 and a top retainer component 55.Earlier top retainer component 55 is inserted groove 402, its body portion 551 is located in being communicated with in the pore 53 of groove 402 and groove 401, top retainer component 55 has a ring-type shoulder 552, can end with inner roof wall 404 cards of groove 402, its central authorities form runner 52, one end extends to form a thimble 553, and then insert bounding means 54, bounding means 54 has a ring-type perisporium 541, one end is toward interior extension one shoulder 542, and after bounding means 54 withstood the inner roof wall 404 of groove 402,404 of its shoulder 542 and inner roof walls had a gap 543, make on top retainer component 55 is limited between the gap 543, following displacement embeds sleeve 51 at last.French mouth 60 also includes a resilient sleeve 61, a bounding means 64 and a top retainer component 65, and its group mode is identical with American mouth 50.
The mode that present embodiment urges resilient sleeve 51,61 resiliently deformables is with to commonly use mode different, but the seesaw-type mechanism for automatically switching that switch piece 90 of the present invention is adopted still can directly be diverted to before the aforementioned patent on the valve joint shown in the case.
Present embodiment includes a pressure holding piece 70 in addition, its tool one bottom 71,71 2 sides extend in parallel out two arms 72 (as Fig. 1, shown in Figure 5) from the bottom, housing 40 is contained between two arms 72 of pressure holding piece 70, one pulling piece 80 is hubbed on two arms, 72 tops of pressure holding piece 70 with a latch 81, and housing 40 is spacing, and the dual side-edge of housing 40 is respectively established a groove 45,72 of two arms of pressure holding piece 70 are contained in two grooves 45, normally are shifted in order to guiding pressure holding piece 70.Pulling piece 80 has biend 82,83, wherein first end face 82 to the distance R 1 of pivot 81 central points less than the distance R 2 of second end face 83 to pivot 81 central points, under unused state, as shown in Figure 4, the bottom 71 and two of pressure holding piece 70 connects the resilient sleeve 51 of mouth, 61 bottom butts, groove 406 bottom surfaces 407 butts that first end face of pulling piece 80 and housing 40 end faces are default, pressure holding piece 70 bottoms 71 corresponding two sleeves 51,61 position respectively is provided with a perforation 73,74, perforation 73, each sheathed lead ring 75 in 74,76, lead ring 75,76 with resilient sleeve 51,61 bearing surface 751,761,511,611 are the conical surface butt.
During use, as shown in Figure 6, American mouth 50 is connected American valve cocks (Schrader valve) (among the figure shown in the imaginary line 110), the thimble 553 of top retainer component 55 pushes up the valve of valve cock, pushed to and moved, and the swing arm 91 of backing down switch piece 90, make pore 53 be open shape, another swing arm 92 then moves down and closes another pore 63, switching pulling piece 80 makes it switch to as shown in Figure 6 use shape by unused state shown in Figure 4 then, this moment, pulling piece 80 was with second end face 83 and housing 40 butts, and force the bottom 71 of pressure holding piece 70 to recline toward housing 40, thereby oppress two resilient sleeves 51,61 distortion, wherein resilient sleeve 51 is just clamped American valve cock 110, inflates action.
As shown in Figure 7, if be connected French valve cocks (Presta valve) (among the figure shown in the imaginary line 120) with French mouth 60, top retainer component 65 is subjected to move in the ejection and backs down swing arm 92, make pore 63 be open shape, and another swing arm 91 is toward moving down and close pore 53, pull pulling piece 80 then and force resilient sleeve 51,61 distortion, and clamp French valve cock 120 with resilient sleeve 61.
After inflation is finished, only need turn back pulling piece 80 and make it, can allow resilient sleeve 51,61 restore to the original state, and decontrol the valve cock of clamping with first end face 82 and housing 40 butts.
The present invention is with the roll structure of seesaw structure replacement aforementioned patent case, and its structure is simplified, and operates infallible.
