AIR PUMP HAVING PIVOTAL ATTACHMENT

摘要

An air valve connecting device includes a housing having an inlet mouth, a sliding member engaged in the housing and having a pathway for receiving the pressurized air from the inlet mouth, a rotary member rotatably engaged with the housing and having two or more compartments each for receiving a gasket and an inflation valve, the rotary member is rotatable relative to the housing for selectively aligning either of the compartments of the rotary member with the chamber of the housing and the sliding member, and a hand grip includes a cam member attached to the housing with a pivot shaft and engaged with the sliding member for forcing the sliding member to force the gaskets to engage with the inflation valves respectively.

1. An air valve connecting device comprising:
a housing including a chamber formed therein, and including an inlet mouth having an entrance formed in said inlet mouth and communicating with said chamber of said housing for guiding a pressurized air to flow from said inlet mouth into said chamber of said housing, said housing including a pivot axle extended therefrom, a sliding member slidably engaged in said chamber of said housing and extendible out of said chamber of said housing, said sliding member including a pathway formed in said sliding member for selectively aligning with said entrance of said inlet mouth and for receiving the pressurized air from said inlet mouth, a rotary member rotatably engaged with said pivot axle for allowing said rotary member to be rotated relative to said housing, said rotary member including a first compartment and at least one second compartment formed therein, a first gasket engaged in said first compartment of said rotary member for engaging with a first inflation valve, said rotary member being rotatable relative to said housing for selectively aligning said first compartment of said rotary member with said chamber of said housing and said sliding member, at least one second gasket engaged in said at least one second compartment of said rotary member for engaging with a second inflation valve, said rotary member being rotatable relative to said housing for selectively aligning said at least one second compartment of said rotary member with said chamber of said housing and said sliding member, and a hand grip including a cam member partially attached to said housing with a pivot shaft, and said cam member being engaged with said sliding member for selectively forcing and moving said sliding member onto of said chamber of said housing and to force said first and said at least one second gaskets to engage with said inflation valves respectively.
