Abstract
The utility model relates to a joint structure of an inflating device using an air storage cylinder. A holding chamber for the extending of the valve nozzle of an inflating product is arranged at a casing, and an elastic link block and a pushing element contacted with the link block are arranged in the holding chamber. The casing is also provided with an inserting hole for inserting the bottle nozzle of a gas storage bottle, and the hole extends to the perisporium of the holding chamber. An air hole penetrates from the inner end of the inserting hole to the holding chamber, and a movable valve member is arranged at the inner end of the inserting hole. The air hole is plugged by the movable valve by the pushing of the air pressure of the gas storage bottle in ordinary times. A pressing handle is pivoted on the casing, and is contacted with the pushing element when pressed. The elastic link block is deformed by the pressing, and is tightly contacted with the valve nozzle. When the pushing element is moved, the valve member which extends in the holding chamber is returned back by a pushing bevel on the peripheral surface, and the air hole is opened.
