Abstract
A dual-gauge air pump has two round dial pressure gauges that are configured in a back-to-back arrangement, i.e. 180 degrees to each other, and to rotate through 360 degrees simultaneously for a user's easy observation.
Claims2
A dual-gauge air pump comprising:
- a barrel;
- a piston, being installed in the barrel;
- a pumping shaft, having one end fixed to the piston and an opposite end jutting out one end of the barrel;
- a gauge casing, having one end fixed to an opposite end of the barrel and being provided with two round dial pressure gauges, in which one is a high-pressure gauge and the other is a low-pressure gauge, wherein the two pressure gauges are on each other's back, facing the exterior, and communicated with the barrel through respective air paths;
- and
- a nozzle casing, being pivotally connected to an opposite end of the gauge casing and freely rotatable through 360 degrees, containing therein a nozzle assembly, and being communicated with the barrel through an air path.

- a barrel;
- a piston, being installed in the barrel;
- a pumping shaft, having one end fixed to the piston and an opposite end jutting out one end of the barrel;
- a handle, being fixed to an opposite end of the piston;
- an air guide, being installed in the barrel and having an exposed end;
- a hose, having one end connected to an exposed end of the air guide;
- a nozzle, being fixed to an opposite end of the hose;
- an air-guiding path, being communicated with the air guide;
- and
- a gauge casing, being provided with two round dial pressure gauges, in which one is a high-pressure gauge and the other is a low-pressure gauge that are on each other's back and facing the exterior, and having laterally a post that is formed centrally an air path running from the exterior to the interior, wherein the two dial pressure gauges are communicated with the air path respectively and the gauge casing has its post pivotally connected to the air-guiding path so as to be freely rotatable through 360 degrees.
