Patent ID: 8210501

Claim:
An inflation valve comprising: a longitudinal valve body having an axially extending hole disposed therein, a projecting edge arranged in the axially extending hole, a round through hole disposed on a center of the projecting edge, and an alignment member formed by at least one projecting body and/or one concave slot arranged on an inner surface of the through hole; a valve member mounted in the axially extending hole of the longitudinal valve body having a valve head whose rear end is disposed with a valve stem connected with an air intake member; the air intake member having an axial hole connecting with the axially extending hole of the longitudinal valve body; the valve head arranged with a neck part for being sleeved with a seal ring while the valve member together with air intake member are formed integratedly; wherein an alignment member is disposed on an outer edge of the valve head and having at least one projecting body and/or one concave slot corresponding to the alignment member on the inner surface of the through hole of the longitudinal valve body; and an elastic member sleeved on the valve stem of the valve member while one end of the elastic member presses against a rear end surface of the projecting edge of the longitudinal valve body and the other end thereof presses against a stopping part of the air intake member of the valve member; wherein while being assembled, the valve member inserts into the axially extending hole of the longitudinal valve body and the valve head moves forward to pass the through hole by the alignment member on the outer edge of the round valve head of the valve member being aligned with the alignment member on the through hole of the longitudinal valve body; the valve head is rotated by an angle so as to make two alignment members in staggered positions for finishing the assembling; by elasticity of the elastic member, the valve head of the valve member presses and locks onto the round through hole of longitudinal valve body tightly and the inflation valve is in a closed state; while being disassembled, the two alignments are rotationally aligned so that the valve head is turned back and moved out of the through hole.
