Description

The double purpose air valve device

Technical field

Model utility relates to a kind of double purpose air valve device, and it can conveniently connect establishes the multi-form joint of inflating, and treats inflatable product and inflates operation.

Background technique

Common air-inflating device only has the single form structure of American valve or French valve, can't inflate operation for multi-form product of inflating joint, and essential standby multi-form air-inflating device respectively causes user's acquisition cost burden and portably uses quite inconvenience.

People are researching and solving this problem always, as " tool automaticallyes switch and selects to connect the inflator valve joint of mouth " scheme of application number 200610065585.0.This scheme comprises: a head shell, this head shell tool one gas-entered passageway; This branch was communicated with above-mentioned gas-entered passageway in housing is located in the chamber to the chamber in one minute; Two connect nozzle assembly, are located in this head shell, and each is communicated with to the chamber with described branch with a runner, and its connection place forms a pore respectively; One switch piece is hubbed on described branch to indoor with the centre, and the pivot both sides form a swing arm respectively, and described two swing arms are that the axle center swings up and down with institute's pivot, and one of them closes corresponding two and connects a wherein pore of nozzle assembly with two swing arms.

The switch piece of this scheme is actual to be with the seesaw principle, when seesaw other the limit design of decline naturally of rising on one side, when using first to connect mouth, utilize on the valve that is connected and push away switch piece, make the runner of top be the unlatching shape, and other side of switch piece descends and block another runner, and an order wherein runner that is connected with valve is held open.

Though it has the mouth that connects of two kinds of different specification sizes, and can select one and select for use according to product is multi-form, still complicated in the right design, on actual the use gas leakage or the fragile phenomenon of structure are arranged easily then, its reason is as follows:

One, utilize two to connect each top retainer component in the nozzle assembly and push against and connect nozzle assembly and rise with the pushing and pressing switch piece, and push runner open as the seesaw principle, and with switch piece in addition side seal close another runner, so switch piece of the seesaw member of must pulling in addition in the design, reach two groups and can rise and fall connect nozzle assembly, member is various relatively.

Two moreover switch piece system utilize the root edge periphery to fill in the runner hole, so its precision want precisely, otherwise the defective products that Yi Chenghui leaks gas, relative processing cost also can improve; With the strength of switch piece jam-pack in the runner hole, actual is to be caused via the strength of pushing up on the top retainer component by another switch piece again, so established not at that time when valve and top retainer component group, connecing nozzle assembly can't push away switch piece when pulling to the extreme higher position, just can cause gas leak phenomenon; The start that connects nozzle assembly and switch piece simultaneously is the friction that can cause the two, must be the antifriction material, otherwise easily causes abrasion because of long-term the use, and then makes product gas leakage, and other connects nozzle assembly and switch piece as if then increasing cost of material with the antifriction material.

Summary of the invention

In order to overcome the prior art above shortcomings, the utility model provides a kind of double purpose air valve device, establishes the multi-form joint of inflating can accurately switch gas flow, conveniently to connect, and fast treats the inflation operation of inflatable product.
