Folding Mechanism for Playground Bar

Abstract

A folding mechanism for a game bed guard bar. The left and right guard bars located on both sides include a housing, first and second swing clips, first and second movable pieces, first and second elastic mechanisms, first and second The second swing piece, the pull cord, one end of the left and right guard rods respectively extend into the gap, and the lower part of the other end can swing up and down with the corresponding horizontal axis as the center of the circle, the swing clips are respectively connected with the corresponding guard rods and the movable piece, and the movable piece is connected with the movable piece. The corresponding swinging pieces are movably connected, and the swinging piece is movably placed in the piercing rod, and the piercing rod can be moved up and down and placed in the vertical strip-shaped cavity. The side of the housing extends out of the housing. Its advantages are: the inventive folding mechanism adopts a "herringbone" linkage structure, so that the left and right guard bars can be unfolded and folded synchronously, and the guard bars can be automatically locked and unlocked after unfolding, and the left guard bar does not interfere with each other when unfolded and folded. It not only reduces the pulling force on the pull cord, but also makes the stacking mechanism more flexible and labor-saving.

Description

technical field [0001] The invention relates to the technical field of making a children's game bed, in particular to a folding mechanism for a play bar guard bar. Background technique [0002] There is an existing Chinese utility model patent with the application number CN201320434899.9 titled "A Kind of Beam Folding Joint for Children's Amusement Bed", which discloses a structure. It also includes a crossbeam connecting piece whose two ends are respectively hinged with the first half-beam and the second half-beam, and a step holder is fixed on the crossbeam connection piece, and the two sides of the step holder are provided with Locking steps, the first half-beam and the second half-beam are respectively hinged with locking blocks that can be locked on the locking steps, and the locking blocks are connected to the beam stay rope , Pressing torsion springs are respectively provided between the locking block and the first half-beam and the second half-beam. The purpose of ...

Problems solved by technology

But its disadvantage is that the structure of the folding mechanism is complicated, there are many parts, and the production cost is high, and the stability of this folding joint is low, and the fixing fastness is not enough, so its structure still needs to be improved.
