Title:
MULTIPURPOSE ROTARY LOCKING CHAIN AND POSITIONING AND STORAGE DEVICE FOR SERIES ROTARY LOCKING CHAIN
Document Type and Number:
WIPO Patent Application WO/2023/109542
Kind Code:
A1
Abstract:
A multi-purpose rotary locking chain, which achieves the function of rotating and locking any two connected chain blocks (2a-2h) within a specified angle range by means of axially shifting a movable locking shaft (1). The setting of non-perfectly-circular cross-sectional shapes of the movable locking shaft (1) and a locking shaft hole can achieve the function of locking and unlocking any two connected chain blocks (2a-2h) at different locking angles. By setting a certain angle between rotation axes of adjacent connecting ends of a series rotary locking chain, the direction of relative rotation between the connected chain blocks (2a-2h) is adjusted. The rotary locking chain can be widely applied to various fields such as daily life and industry. Further provided is a positioning and storage device for a series rotary locking chain. The device can unfold, position and store a series rotary locking chain.
