Abstract
A tire valve assembly is disclosed. The tire valve assembly includes a gas nozzle structure, a movable rod, an air pipe, an elastic close contact pad, a screw nut, an elastic O-ring and a dust cap. The tire valve assembly can use a punched hole on the end of the movable rod to receive the tire repair liquid flowing into the air pipe. Take out the movable rod during maintenance to remove the tire repair liquid in the punched hole. When the movable rod is reinstalled in the air pipe, the tire repair liquid remaining on the inner wall of the air pipe will also be squeezed out of the air pipe. With this, the tire repair liquid will no longer block the tire valve assembly.
Claims12
A tire valve assembly, comprising:
- a gas nozzle structure, comprising:
- an air intake tube, having a first external thread section formed on an upper end thereof externally, and a second external thread section formed below the first external thread section;
- a movable screw, mounted inside the air intake tube, wherein the movable screw has a third external thread section formed on a top end thereof, and a first seal ring is fixedly set below the third external thread section;
- and
- a limiting nut, mounted on the third external thread section, being rotatingly adjusted to limit a displaceable length of the movable screw relative to the air intake tube;
- a movable rod, successively comprising a connecting section, an indented section, a tire repair liquid accommodation section and a first installation section from top to bottom, wherein the connecting section is connected to a lower end of the movable screw, a second seal ring is fixed to the outside of the first installation section, at least one punched hole non-parallel to an axis of the movable rod is formed in the tire repair liquid accommodation section, and an outer diameter of the indented section is smaller than that of the connecting section, that of tire repair liquid accommodation section and that of the second seal ring;
- and
- an air pipe, successively comprising a fourth external thread section, a second installation section and a round mounting seat from top to bottom externally, and successively comprising a first internal thread section and a smooth section from top to bottom internally, wherein the air intake tube is able to be fixed on an upper end of the air pipe by rotationally connecting the second external thread section and the first internal thread section, and an inside diameter of the smooth section is substantially equal to or less than an outer diameter of the second seal ring so that when the movable rod is pushed and pulled by the movable screw to move within the air pipe, friction exists between the second seal ring and the smooth section.
