Title:
LEG TUBE SLIDING LOCKING MECHANISM FOR OPENING AND CLOSING FOLDING TENT
Document Type and Number:
WIPO Patent Application WO/2021/184715
Kind Code:
A1
Abstract:
Disclosed is a leg tube sliding locking mechanism for opening and closing a folding tent, the mechanism comprising a sliding support sleeved on a leg tube, a jumping bead, and a V-shaped spring. One end of the V-shaped spring is connected to the jumping bead, and the other end of the V-shaped spring is fixed on an inner wall of the leg tube. A bushing is also fittingly mounted on an inner wall of the sliding support. A pressing piece extends downward at an upper end of the bushing, and a lower end of the pressing piece extends to a lower end of the sliding support. The pressing piece covers the jumping bead. In the present invention, the bushing is fitted inside of the sliding support, thus the jumping bead need not be directly pressed when the folding tent is folded and contracted; moreover, a pressing piece having a larger area is pressed, thus achieving easy contraction and preventing hands from being clamped. The transformation of the described structure is simple and easy to implement.
