Abstract
The invention provides a reverse self-locking mechanism of a rotating shaft, comprising the rotating shaft, a stop disc, a stop hook, a supporting plate and a fixed shaft, wherein a rotating shaft hole is formed in the supporting plate, the supporting plate sleeves the rotating shaft through the rotating shaft hole, the rotating shaft can rotate freely, the stop disc is mounted on the rotating shaft and rotates along with the rotating shaft, the fixed shaft is fixed on supporting plate, the stop hook comprises a fixed end and a free end, the fixed end is fixed on the fixed shaft, the stop hook rotates freely around the fixed shaft, and the free end is lapped on the stop disc. When a weight is lifted, the free end of the stop hook slides freely on the stop disc; and when the weight stops at an arbitrary position, the free end of the stop hook stops the stop disc from rotating. According to the reverse self-locking mechanism of the rotating shaft provided by the invention, as the design of the stop disc and the stop hook is adopted, the reverse self-locking mechanism of the rotating shaft cannot influence operation of lifting equipment during the lifting; however, when the lifting is stopped to be kept at a proper height or the weight drops suddenly in case of a special condition, the stop hook can quick lock the stop disc and the rotating shaft to avoid from happening an accident, and therefore the safety is greatly improved.
