Abstract

The invention discloses an inflatable device, which includes a support tube with a hollow tubular structure. One end of the support tube is opened as the intake end, and the other end is opened as the exhaust end. The support tube is between the intake end and the exhaust end. The middle part of the pipeline between them is provided with a ventilation ring groove adjacent to the exhaust end; an air needle is slidingly matched in the support tube, and the air needle includes a support base and a needle tube connected with the support base, the support base is slidably arranged in the support tube and It can move along the central axis of the support tube. The support base is provided with a radial air hole a and a radial air hole b arranged along its radial direction and having at least one open end. The radial air hole a and the radial air hole b are independent of each other and mutually If it is not connected, the side of the support seat facing the intake end of the support tube is provided with a communication hole for connecting the radial air hole a and the air intake chamber, and the support seat is provided with a connecting hole for connecting the radial air hole b, The central airway of the needle lumen.

Description

technical field [0001] The invention relates to an inflatable device, in particular to a portable inflatable device applicable to inflatable balls such as basketballs and footballs. Background technique [0002] The existing inflation equipment for inflatable balls such as basketballs and footballs is a hollow air needle. The air inlet end of the air needle is connected to the exhaust port of compressed air equipment such as an air cylinder. Gas process; the current gas needle is small in size, the needle tube of the gas needle extends long and the exhaust end of the needle tube is relatively sharp, which makes it inconvenient to carry the gas needle, and there are safety hazards in the process of children's use. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide an inflatable device that is easy to carry and has the function of hiding the needle tube of the air needle, so as to improve...
