For this reason, many efforts are made by the technical staff, such as the chinese patent of patent No. ZL201320434899.9, a children entertainment bed cross beam folding joint (issued notice No. CN 203354119U), which includes a first half beam, a second half beam, and a cross beam connecting piece with two ends hinged to the first half beam and the second half beam respectively, a step clamping seat is fixedly arranged on the cross beam connecting piece, two sides of the step clamping seat are provided with clamping steps, the first half beam and the second half beam are respectively hinged with a clamping block capable of being clamped on the clamping steps, the clamping block is connected with a cross beam pull rope, and a pressing torsion spring is respectively arranged between the clamping block and the first half beam and the second half beam. The folding joint of the folding children entertainment bed cross beam can be driven by the folding stay rope. Although the operation brings great convenience, the folding structure is complex, the parts are more, and the production cost is high; meanwhile, the folding structure has lower stability, insufficient fixation fastness and potential safety hazard.
As an improvement, the applicant discloses a chinese utility model patent application publication of folding mechanism of play yard guard bar (publication No. CN104545130 a), see application No. 201410857407.6. In this application, rapid folding and unfolding is achieved by four bar linkages of guard bars, movable plates, swinging clips and swinging plates. The locking and unlocking are not mutually interfered after the guard bar is unfolded, and the operation is flexible and labor-saving. However, the stacking mechanism is complex in structure, more in parts, higher in product precision requirement in the manufacturing process, and inflexible and convenient due to the resistance of the springs in unlocking.
On the basis, the utility model is published in China patent application No. 201510243167.5 of the folding device of the game bed guard bar (publication No. CN 104799624A), the application adopts a magnet structure for resetting and locking, the magnet can adsorb the movable piece to accelerate the resetting speed and reduce the resetting force, and when the guard bar is completely unfolded, the magnet can continuously adsorb the movable piece to prevent the movable piece from moving again, thereby playing the role of locking the guard bar and improving the stability of the folding device. The unlocking operation is quick, that is, the unlocking operation is free from resistance only by disengaging the magnet, so that the unlocking operation can be instantaneously performed.
The Chinese patent application with the application number 201610297474.6 is referred to as a folding structure of a guard bar of a game bed (application publication number CN 105768705A), and the internal structure of the guard bar is improved, so that false locking is avoided, and safety accidents caused by the false locking can be avoided.
