The invention provides a locking device with a hand-operated device. The locking device comprises the hand-operated device, a handwheel and a padlock, wherein a fixing plate is mounted on the box body of the hand-operated device; the locking device further comprises a bolt penetrating the fixing plate; a plurality of through holes matched with the bolt are uniformly distributed at the circumference of the handwheel; a locking hole is formed at the end part of the bolt; and the padlock is hung on the locking hole. The locking device has the benefits of simple structure and good locking effect.
Description
Technical field [0001] The invention relates to a locking mechanism, in particular to a locking device of a worm drive. Background technique [0002] At present, most of the locking devices used in worm transmissions use a support plate fixed on the box body of the manual device, a hole is punched on the support plate, and a chain passes through the hole on the support plate and the hand wheel to lock it with a padlock. Since the handwheel generally has three evenly distributed wheels, the chain cannot completely lock the handwheel, and accidents often occur when non-operators misuse the handwheel. Contents of the invention [0003] In order to overcome the problem that the locking device of the existing manual device cannot completely lock the hand wheel, and non-operators often cause accidents due to misoperation of the hand wheel, the present invention provides a locking device for a worm drive. [0004] The technical solution adopted by the present invention to solve ...
