Title:
EQUATORIAL MOUNT LOCKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/024314
Kind Code:
A1
Abstract:
An equatorial mount locking device comprises a declination locking handle (20), a declination locking block (19), a copper pad (8), a declination worm wheel locking nut (7), a declination shaft locking nut (4), a tensioning block A (10), a tensioning block B (12), an hour angle locking handle (18), a lens holder base (11), a declination base (14), a declination worm shaft (5), a declination worm wheel (13), an hour angle base (1), an hour angle worm shaft (16), an hour angle worm wheel (17), an hour angle base bearing (3), a declination shaft (9), and a right ascension shaft (2). The equatorial mount locking device has reasonable design and an advanced structure. The arrangement of the tensioning block A (10) and the tensioning block B (12) enables tight engagement between the declination worm wheel (13) and the right ascension shaft (2) and between the hour angle worm wheel (17) and the declination shaft (9), thereby increasing precision of an equatorial mount.
