Patent ID: 11635478

Abstract:
A fastening device for releasably fastening a probe (1) to an NMR magnet (2). An insert part (3) fastens the probe to a retaining system (4) connected to the magnet. A force-variable connection is established by the insert part with spring elements (8). The probe fastens to the insert part with rigid retaining elements (6). When closed, a connection without mechanical play exists between the insert part and the retaining elements when the spring elements are under tension. An annular disc-shaped pretensioning element (9) is arranged between the insert part and the retaining system. By rotating the pretensioning element relative to the insert part, the pretensioning element presses on and pretensions the spring elements. When open, the spring elements and the retaining elements are configured to connect with a mechanical play of 0.5 to 5 mm between the insert part and the retaining elements when the spring elements are pretensioned.
