THERMAL RADIATION SHIELD FOR SUPERCONDUCTING MAGNET SUPERCONDUCTING MAGNET AND MAGNETIC RESONANCE IMAGING DEVICE

摘要

The invention relates to an inner tube, an outer tube disposed about the periphery of the inner tube, and an annular end disposed between the inner tube and the outer tube and fixedly connected to an edge of the inner tube by an inner edge of the annular endcap Wherein the first toothed portion is formed at an outer edge of the annular end cover and the first toothed portion is engaged with a second toothed portion formed by an edge of the outer tube, Lt; / RTI Since the annular end cap adopts a toothed structure instead of a decorative boundary structure as in the prior art, it is only necessary to perform a simple cutting process on the raw material to obtain the annular end cover and the first toothed portion formed on the outer edge thereof , Thereby avoiding complicated punching, spinning and similar processing, and saving processing and time costs.
