The invention relates to a rushing prevention type pneumatic fast joint, which comprises an air inlet connecting sleeve, a sealing baffle ring, an air inlet sealing ring, a valve core, a slide sleeve spring, a valve core anti-contraction bead, a sliding protection sleeve, an inner slide sleeve, an inner slide sleeve anti-contraction bead, an axial position limiting element, an air outlet sealing ring, a middle sealing ring, a valve core inner spring and a valve core outer spring, wherein the valve core is in a closed state before a bleed plug is plugged, the bleed plug pushes the inner slide sleeve and the valve core to simultaneously and leftwards move when the bleed plug is plugged, the valve core is in an open state when an air outlet hole arranged on the valve core exceeds the air inlet sealing ring, the valve core anti-contraction bead is in reliable contact with an opening step when the valve core anti-contraction bead is in contact with the opening step of the valve core, and the valve core is ensured to be in a reliable ventilation state. When the bleed plug needs to be dismounted, the valve core rightwards moves under the effects of the valve core outer spring and the air pressure, the valve core is in the closed state when a closing step is in contact with the valve core anti-contraction bead, the bleed plug only receives the elasticity of the valve core spring when being disconnected, and the reverse rushing force is very small.
