Description
Technical field
The present invention mainly discloses a kind of air valve device for pump, espespecially a kind of air valve device that can switch fast to provide American valve or French valve to use.
Background technique
With reference to U.S. Patent number US5,960, No. 815, it discloses a kind of air valve of inflator joint, and this air valve of inflator joint includes a housing, a body and two connects mouth and is contained in housing, and a pulling piece is located on housing with a latch.Due in body respectively group established two and connect mouth and make this air valve of inflator joint there is the excessive shortcoming of volume, because air valve of inflator joint is widely used on bicycle tyre, the excessive volume of air valve of inflator will make in gas replenishment process body and bicycle wheel frame spoke produce to interfere and cannot inflate smoothly.
With reference to No. 2008/0236675th, U.S. Patent Publication No., it discloses a kind of air valve of inflator, its wind fairing head has the assembly hole and the adapter that communicate, assembly hole top group is established spanner, bottom is provided with can be for the American tuyere that connects mouth and penetrate location, be characterised in that: assembly hole is provided with one in tuyere top can connect the holder that mouth penetrates for French, holder top is provided with the guide hole of bringing together downwards, then assembly hole sliding force-filling device that closed between holder and spanner, between force-filling device and holder, be provided with resetting spring, force-filling device bottom is provided with the movable claw corresponding with guide hole, in this force-filling device, connect a thimble with spring, in order to do in the time that spanner interlock force-filling device moves down, this movable claw can force tuyere distortion and clamp American valve or French connects mouth, make thimble really inflate.This kind of air valve of inflator improved the excessive problem of air valve of inflator volume, but need make this movable claw can possess effect that folder is pulled or departed from caulking groove across one section of free gap between the movable claw of air valve of inflator force-filling device and thimble, therefore this force-filling device needs establish in addition a center pillar in inside and this tailstock spindle is located to this center pillar to provide thimble a sliding path, make this air valve of inflator inside there is baroque shortcoming, and free gap between thimble and movable claw also make the volume of this air valve of inflator still have the space of improvement.And, when this thimble slides when near the fixture block of movable claw, thimble only few part is sheathed on this center pillar, and therefore the easy beat of thimble even departs from sliding path and causes fixture block not correspond to this caulking groove, will cause the damage of movable claw or thimble if now rashly pull spanner.In addition, air valve of inflator assembly hole bottom group is provided with a tuyere, press down and make tuyere be out of shape to provide French valve or American valve location, but this kind of clamping mode stability is not good, and clamping tuyere is easy to wear, must often change by force-filling device.
With reference to U.S. Patent number US7,588, No. 048, it discloses a kind of air valve device, major character is the gas nozzle plug group seat in interior spatial placement one end with the shell of air-filled pore with chamber, and this chamber inner side combination one has the gas nozzle plug of penetration hole, and this penetration hole recombinant one has the top core barrel of air outlet hole, and this top core barrel cannot depart from this gas nozzle plug, the internal diameter of this shell air-filled pore is provided with and can be screwed together in the externally threaded internal thread of American valve.Therefore in the time that wish group is established American valve, American valve can be screwed together in to internal thread to reach airtight.Because this design only has the internal thread that is applicable to American valve, if when therefore wish is assembled French valve, must an external conversion adapter in air valve device, again French valve is mounted on to this conversion adapter to reach airtight, the additional volumes that the additional conversion adapter of loaded down with trivial details switching process produces makes operation upper very inconvenient, and conversion adapter is easily lost in handling process, produce on the contrary more shortcomings.
Therefore, the present invention wants get rid of or at least alleviate the problem that prior art meets with, and invents a kind ofly to have the American or French valve of quick switching concurrently and have accurate positioning and the air valve device for pump that volume is little.
Summary of the invention
The technical problem that institute of the present invention wish solves is the above-mentioned disappearance existing for prior art, and object is to provide a kind of processing ease and can significantly reduces volume and avoid this push rod to depart from the air valve device for pump of sliding path.
The present invention is for the air valve device of pump, and it includes a body, a control group and a thimble group.This body comprises a pedestal, and this pedestal has a first end and second end, and this pedestal first end is provided with an attachment hole, and this pedestal second end has a transfer port.This control group is sheathed on this body and can between a primary importance and a second place, rotates relative to this body, this thimble group is slidedly arranged on this body attachment hole and comprises a push rod, when this control group is positioned at this primary importance, this push rod can be along this attachment hole towards this pedestal second end slippage thereby a kind of valve of applicable connection, when this control group is positioned at this second place, this push rod is resisted against the first end of this pedestal and cannot moves thereby the another kind of valve of applicable connection towards the second end of this pedestal.
Can summarize the present invention with regard to the above has advantages of following:
Push rod limited part has similar non-circular profiles to this pedestal attachment hole, and by this control group make this push rod relative to this pedestal rotate and Fast transforms can be corresponding valve, this air valve device that is used for pump has advantages of processing ease.
This push rod can slippage in this pedestal attachment hole, because the attachment hole of this pedestal is solid shape, therefore between this attachment hole and push rod, does not need to increase in addition free gap, can significantly reduce volume and avoid this push rod to depart from sliding path.
This positioning means is mounted between this control group and this body and makes this control group can accurately be positioned primary importance or the second place.
This push rod need not get final product stable slippage in attachment hole thereby have advantages of simple in structure by extra guiding structure.
This installing groove is respectively equipped with the screw thread of corresponding American valve and French with perforation, therefore need not can complete by conversion adapter the assembling of American valve or French valve, and the mode that valve utilization is spirally connected is connected in cap group, what make that valve can be stable in the process of inflating is mounted on cap group.
