Abstract

An inflatable coaxial pressure release device makes use of the insertion relationship between a check valve lantern ring and a draught pipe joint and cooperates with the rotary operation mode of a pressure release control ring to achieve the effects of inflating by screwing tightly and releasing pressure by unscrewing aiming at the inflatable objects. A draught pipe joint is arranged in the pressure release control ring at the front end of the pressure release device and a closed element is sheathed at the back end of the draught pipe joint. The back end of the pressure release device is composed of a check valve lantern ring which is provided with a check valve and screwed to an air sac joint. The front section of the air sac joint is provided with an air-in hole with a back ball arranged in, and the front and back ends of the pressure release device are screwing sheathed by jointing screw teeth inside the pressure release control ring and in the front section of the air sac joint. Therefore, with the rotary control mode of the pressure release control ring, when screwed in to have the check valve lantern ring tightly connected with the draught pipe joint, an object can be inflated; when screwed out to relax, the air emits from the clearance between the check valve lantern ring and the draught pipe joint so as to achieve the two movement functions of both inflating and pressure releasing with a same axis.
