Document Type and Number:
WIPO Patent Application WO/2018/161617
Kind Code:
A1
Abstract:
A folding locking mechanism comprises: a locking box (1); a locking shaft (2), passing through the locking box (1) and capable of rotating relative to the locking box (1), wherein the locking shaft (2) is radially provided with radial locking holes (21) passing through the center of the locking shaft (2); a locking assembly (3), disposed in the locking box (1), wherein the locking assembly (3) comprises locking rods (31) corresponding to the radial locking holes (21) and pushing springs (33) for pushing the locking rods (31) into the radial locking holes (21); an unlocking button (4), wherein one end of the unlocking button (4) is disposed in the locking box (1), the other end is exposed out of the locking box (1), the end of the unlocking button (4) disposed in the locking box (1) is used to push the locking rods (31) away from the radial locking holes (21); and a return spring (5), used to provide a returning force for the unlocking button (4). The folding locking mechanism of the invention has a simple structure and is easy to install. The locking rods (31) and the radial locking holes (21) have a large engagement length and a large contact area, and therefore are more stable when subjected to a force, effectively preventing the locking shaft (2) and the locking box (1) from rotating relative to each other, and meeting use requirements.
