Abstract

A tire-condition sensor for installing on a wheel rim of a tire where the wheel rim defines a wheel rim platform and a valve rod. The tire-condition sensor includes a valve rod, a main body, and two positioning devices. The valve rod is for passing through the valve hole and is fixed on the wheel rim. The main body has a sensor for sensing the condition of the tire, connecting to the valve rod, and defining a positioning direction which is more or less perpendicular to the wheel rim platform. The two positioning devices, positioning on the main body, can move in the positioned direction relative to the main body, adjustably touch the wheel rim platform, and by means of this to firmly fix the tire-condition sensor.

Claims

1. A tire-condition sensor for installing on a wheel rim of a tire wherein the wheel rim defines a wheel rim platform and a valve hole, the tire-condition sensor comprising:

a valve rod for passing through the valve hole and being fixed on the wheel rim;

a main body having a sensor for sensing the condition of the tire, connecting to the valve rod, and defining a positioning direction which is more or less perpendicular to the wheel rim platform; and

two positioning devices, positioning on the main body, that can move in the positioned direction relative to the main body, adjustably touch the wheel rim platform, and by means of this to firmly fix the tire-condition sensor.

2. The tire-condition sensor of claim 1, further comprising an upper plane disposition defined along the main body.

3. The tire-condition sensor of claim 2, further comprising an outer lid for protecting the antenna and a multiplicity of slots for exposing the antenna.

4. The tire-condition sensor of claim 1, wherein the main body comprises two protuberances at both side thereof for protecting the tire-condition sensor.

5. The tire-condition sensor of claim 1, wherein its positioning device is the two-bolt, and the main body has two threaded holes each hole matches with one of the two bolts respectively that can adjustably touch the wheel rim platform of the wheel rim.
