Document Type and Number:
WIPO Patent Application WO/2022/151373
Kind Code:
A1
Abstract:
Disclosed are a stretching-resistant structure for improving the stability of a folding screen and a display apparatus. The stretching-resistant structure comprises: reinforcing rib lines closely attached to the back of the folding screen. Each reinforcing rib line is provided with a plurality of positioning blocks, and the back of the folding screen is provided with a plurality of limit seats that cooperate with the positioning blocks. When the folding screen is unfolded, the positioning blocks cooperate with the limit seats to provide an upward supporting force for the folding screen when the reinforcing rib lines are pulled upwards by means of a lifting apparatus. In the present invention, longitudinal reinforcing steel wires are arranged on the back of the folding screen, and in order to provide support for each display unit, three solutions are provided for arranging the positioning blocks on the reinforcing steel wires so that same cooperate with the limit seats on the back of the folding screen, so that the overall force of the folding screen is balanced and not too concentrated, and the longitudinal stretching resistance of the screen is enhanced. When the folding screen needs to be folded, the lifting apparatus releases the reinforcing steel wires downward, and there is no force connection between the limit seats and the positioning blocks, thus avoiding affecting the folding and unfolding action of the screen.
