Abstract:
The present invention provides a spirit level having reflection bubble which comprises an elongate body, a first surface and a second surface, a cavity which has an opening on the second surface is arranged between the first surface and the second surface; the spirit level arranged in the cavity comprising: a non-opaque body having a slope and a first viewing plane; a bubble component has a longitudinal axis perpendicular to the first surface is mounted in the body of the level, and the first surface is mounted between the first end of the bubble component and the measured surface, the first viewing plane is mounted between the second end of the bubble component and user; the image of the bubble component is formed by the reflection of the slopes; users can observe the image of bubble component from the first viewing plane via reflected by the slope. The present invention provides a spirit level having reflection bubble which using the reflection of light through the interface makes user can observe the bubble component from the front when the user measures the verticality, the spirit level is formed integrally, additional assembly and calibration are not needed, so the manufacturing is simple and the costs of production is low.

Claim (Index 52):
The bubble level according to  claim 41 , wherein the body of the level further comprises a first end and a second end.
