Technical field
The present invention is relevant with inflator, is meant a kind of structure of valve joint of inflator especially.
Background technique
As shown in Figure 1, be the preceding case of novel No. 135498 patent in Taiwan (US 5,960,815), known pump valve joint includes a housing 10, one bodies 18 and two and connects mouth 14,15 and be contained in the housing 10, and a pulling piece 27 is located on the housing with a latch 28.What this patent disclosed is the structure that two valve joints are arranged, and single valve joint structure of commonly using only need dispense one and connect mouth and automatic transfer valve wherein gets final product.Known valve joint must will connect the lowermost end that mouth 14,15 is filled in housing 10, fill in body 18 again, this kind structure makes the dimensional accuracy that connects mouth 14,15 must be very high, and the size that rubber connects mouth 14,15 only needs bigger, it be filled in the housing lowermost end and just be easy to generate difficulty.Moreover when pulling pulling piece 27 and make body 18 produce relative displacements, must overcome the frictional force between body 18 and top seal ring 33 thereof and housing 10 inwalls, the application of force that needs are bigger with housing 10.
Summary of the invention
At the problems referred to above, main purpose of the present invention is to provide a kind of valve joint of inflator, and its assembling is more convenient.
Another purpose of this is to provide a kind of valve joint of inflator, and the application of force was lighter when it used.
For achieving the above object, the valve joint of a kind of inflator provided by the present invention is characterized in that including: a housing, and it has a gas-entered passageway; At least one nozzle assembly that connects is located at described housing, is communicated with described gas-entered passageway, and the described nozzle assembly that connects includes a resilient sleeve; One pressure holding piece has a bottom, and extends two parallel arms from described bottom, and described housing is contained between two arms of described pressure holding piece, and corresponding each described sleeve position that connects nozzle assembly, the bottom of described pressure holding piece respectively is provided with a perforation; One pulling piece, with a latch it is hubbed between described pressure holding piece two arms, it has biend, wherein first end face to the distance of pivot center point less than the distance of second end face to pivot center point, when first end face and described housing butt, the described resilient sleeve that connects nozzle assembly is in relaxed state, when described second end face and described housing butt, the bottom of described pressure holding piece reclines toward described housing, pushes the described resilient sleeve distortion that connects nozzle assembly.
In the technological scheme of the invention described above, the two side faces that described housing is adjacent with described pressure holding piece two arms respectively is provided with a guide groove, guides the guide groove displacement of described pressure holding piece along described housing.
In the above technological scheme of the present invention, two arms of described pressure holding piece are contained in the guide groove of described housing two sides.
In the above technological scheme of the present invention, the perforation of described pressure holding piece bottom respectively is provided with a lead ring, and the bearing surface of described lead ring and described resilient sleeve is conical surface.
Adopt above technological scheme, the present invention assembles very convenient, and it connects nozzle assembly and inserts in the default groove of housing directly location by the outside, and is more fast and convenient than commonly using structure.When pulling pulling piece, pressure holding piece and housing relative displacement, and directly oppress the resilient sleeve distortion, action does not contain the frictional resistance that other assembly is shifted relatively and produces really, than commonly using the laborsaving good operation of structure.

Embodiment
For the effect that describes structure of the present invention in detail and reached, now lift the explanation of a preferred embodiment and conjunction with figs. down.
The embodiment of the invention is to do explanation with two valve joints, and its structure also can apply to single valve joint.
As Fig. 2～shown in Figure 5, the valve joint of this example 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 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 for example use of hand-held pump (Hand Pump) or mini inflating pump (Mini Pump) etc. by flexible pipe.
Two connect nozzle assembly 50,60, are located at housing 40, are communicated with gas-entered passageway 41 respectively, and each connects nozzle assembly and respectively includes a resilient sleeve 51,61, and Local Convex is exposed at outside the housing 40 respectively.
One pressure holding piece 70 has a bottom 71, and extends two parallel arms 72 from the bottom, and housing 40 is contained between two arms 72 of pressure holding piece 70, and sleeve 51,61 positions that bottom 71 correspondences two of pressure holding piece 70 connect nozzle assembly respectively are provided with a perforation 73,74.
One pulling piece 80, with a latch 81 it is hubbed between pressure holding piece 70 2 arms 72, it has biend 82,83, wherein first end face 82 to the distance R 1 of pivot center point less than the distance R 2 of second end face 83 to pivot center point, when first end face 82 and housing 40 butts (as shown in Figure 4), two connect nozzle assembly 50,60 resilient sleeve 51,61 are in relaxed state, can insert for valve cock, when user's switching pulling piece 80 makes second end face 83 with housing 40 butts, the bottom 71 of pressure holding piece 70 reclines (as shown in Figure 6) toward housing 40, extruding connects nozzle assembly 50,60 resilient sleeves that expose 51,61, make its distortion and clamp valve cock.When turn back pulling piece 80 make first end face 82 again with housing 40 butts, promptly unclamp the valve cock of clamping.
In addition, for making action really, between the approximal surface of housing 40 and pressure holding piece 70, be provided with guide groove and guide structures such as guide rail that can cooperate with it or fin.Present embodiment respectively is provided with a guide groove 45 at housing 40 two side faces, and the arm 72 of pressure holding piece 70 then is to be contained in the corresponding guide groove 45 (as Fig. 1, shown in Figure 5), guides pressure holding piece 70 and housing 40 axial relative displacements along guide groove 45 thus.
Present embodiment connects nozzle assembly because of being provided with two, therefore be provided with an automatic switchover part 90 in housing 40, in order to two connected states that connect mouth 50,60 and gas-entered passageway 41 that automatically switch, its operating principle is identical with the preceding case of the patent in the background note, its structure separate case is filed an application, and holds and does not give unnecessary details.
For ease of assembling and guide sleeve deformation direction, the bearing surface 751,761,511,611 that respectively is provided with a lead ring 75,76, two lead rings 75,76 and resilient sleeve 51,61 in two perforation 73,74 of pressure holding piece 70 bottoms 71 is conical surface.
The invention has the advantages that assembling is very convenient, it connects the mouth assembly and is inserted in the default groove of housing by the outside Directly the location is more fast and convenient than commonly using structure. When pulling pulling piece, pressure holding piece and housing relative displacement, and Directly compressing resilient sleeve distortion, action does not contain the frictional resistance that other assembly relative shift produces really, Than commonly using the laborsaving good operation of structure.
