AI Technical Summary
Existing folding tables are prone to buckling at the joints when unfolded because the two tabletops cannot lock themselves, resulting in structural instability. Improper use may cause the tabletop to bend and items to fall.
The device employs a self-locking structure, including a first connector and a second connector that can rotate relative to each other. Utilizing the design of an arc-shaped groove and a button, the first connector is locked into the enlarged hole in the unfolded state. Through the cooperation of a return spring and a convex ring, the connector is ensured to be unable to rotate, thus achieving self-locking. When it is necessary to fold, pressing the button causes the second connector to move along the arc-shaped groove, thereby achieving rotation.
The table features a self-locking mechanism on both tabletops when unfolded, ensuring tabletop stability and preventing bending. The self-locking can only be released by pressing a button, facilitating table folding.
