Bicycle valve convenient for assembly

Abstract

The bicycle valve of the present invention, which is easy to assemble, includes a housing, a valve, and a connecting pipe. The housing has a through-hole, and the inner periphery of the through-hole has an internal thread. The valve includes a valve tube and a valve core. The valve tube has a through-hole, and the inner periphery of the through-hole has a first connecting part. The valve core is disposed in the through-hole and can selectively close the through-hole. One end of the connecting pipe has an external thread and the other end has a second connecting part. The external thread is screwed into the internal thread, and the second connecting part is connected to the first connecting part. The connecting pipe has a through hole that connects the through-hole and the through-hole. The valve can be easily assembled onto the wheel rim through the above structure.

Claims

1. A bicycle valve that is easy to assemble, comprising: a housing having a through-hole, the inner periphery of which has an internal thread; a valve valve including a valve tube and a valve core, the valve tube having a through-hole, the inner periphery of which has a first connecting portion, the valve core being disposed in the hole and capable of selectively closing the hole; a connecting pipe having an external thread at one end and a second connecting portion at the other end, the external thread being screwed onto the internal thread, the second connecting portion being connected to the first connecting portion, the connecting pipe having a through hole connecting the through-hole and the hole.

2. The bicycle valve as described in claim 1, wherein the housing forms a first diameter along its maximum width at its radial outer periphery, and the valve tube forms a second diameter along its maximum width at its radial outer periphery, the second diameter being no greater than the first diameter.

3. The bicycle valve as described in claim 2, wherein an annular protrusion is provided on the outer periphery of the connecting pipe, the annular protrusion being disposed between the external thread and the second connecting portion, and the width of the annular protrusion along the radial direction of the connecting pipe being equal to or less than the second diameter.

4. The bicycle valve as described in claim 1, wherein the second connecting part is screwed to the first connecting part.

5. The bicycle valve as described in claim 3, wherein a first airtight ring and a second airtight ring are provided on the outer periphery of the connecting tube, the first airtight ring being sleeved on the side of the external thread opposite to the ring protrusion and abutting against the inner periphery of the assembly hole, and the second airtight ring being sleeved between the second connecting portion and the ring protrusion and abutting against the inner periphery of the insertion hole.

6. The bicycle valve as described in claim 1, wherein an airtight portion is provided on the inner periphery of the insertion hole, an air inlet is recessed at one end of the valve core opposite to the housing, a side hole is provided on the valve core radially along the air inlet, the side hole communicates with the air inlet and connects to the outer periphery of the valve core, an airtight member is fitted on the outer periphery of the valve core, the airtight member abuts against the airtight portion, so that the valve core closes the insertion hole, and the valve core can move toward the housing, so that the airtight member disengages from the airtight portion and opens the insertion hole.

7. The bicycle valve as described in claim 6, wherein the valve includes a pressure cap that is screwed onto the outer periphery of the valve core, wherein when the pressure cap is locked, it abuts against the end of the valve tube opposite to the housing, preventing the valve core from moving relative to the valve tube, and when the pressure cap is released, it disengages from the valve tube, allowing the valve core to move relative to the valve tube.

8. The easily assembled bicycle valve as described in claim 7, wherein the valve includes a cap that is detachably fitted onto the valve tube and covers the valve core opposite to the housing.
