The folding frame as described in claim 1, characterized in that, The plurality of uprights includes a first upright, and the other end of the first connecting rod is rotatably connected to the first upright; The linkage mechanism includes: A linkage component is movably mounted on the corresponding first upright in the vertical direction and is connected to a foldable component on the support frame other than the first upright, so that the foldable component drives the linkage component to move downward during the process of the support frame changing from the supported state to the folded state. A first linkage mechanism is drivenly connected between the linkage member and the locking member; and The second linkage mechanism has one end connected to the first linkage, and the other end connected to the linkage drive during the movement stroke of the linkage.
3. The folding frame as described in claim 2, characterized in that, The first linkage mechanism includes: A turntable, rotatably mounted on the upper end of the first upright, is connected to the linkage at a position offset from its rotation center, so as to drive the turntable to rotate during the movement of the linkage; and, The cable is wound at one end to the turntable and connected to the locking element at the other end.
4. The folding frame as described in claim 3, characterized in that, The linkage is connected to the turntable to drive the turntable to rotate during its vertical movement; one of the turntable and the linkage is provided with a connecting protrusion, and the other is provided with a mating groove that engages with the connecting protrusion.
5. The folding frame as described in claim 2, characterized in that, The second linkage mechanism includes: A drive unit is movably disposed at the upper end of the first upright and located at the midpoint of the downward travel of the linkage; and, A transmission mechanism that drives the drive unit and the first connecting rod.
6. The folding frame as described in claim 5, characterized in that, The linkage is provided with a pushing part, and the driving part is provided with a mating part. The mating part is located below the pushing part and is spaced apart from the pushing part. The driving part is provided with a first rack part, which extends in the vertical direction. The transmission mechanism includes: A first gear section is rotatably mounted on the upper end of the first upright and meshes with the first rack section; and, The second gear is fixedly mounted on the first connecting rod and meshes with the first gear.
7. The folding frame as described in claim 2, characterized in that, The frame also includes a connecting bottom rod rotatably connected to the lower end of the first upright. In the supported state, the connecting bottom rod rotates away from the first upright. In the folded state, the connecting bottom rod rotates close to the first upright. The rotation of the connecting bottom rod drives the linkage to move. The lower end of the linkage is connected to a second rack portion, which extends in the vertical direction. The connecting base rod is provided with a third gear, which meshes with the second rack, so that when the connecting base rod is rotated and folded, the second rack is driven to move downward, thereby driving the linkage to move downward.
8. The folding frame according to claim 1, characterized in that, The upper rod assembly also includes a hinge seat, the first connecting rod and the second connecting rod are respectively rotatably connected to the hinge seat, and the hinge seat is provided with a mating part; The locking member is movably disposed along the length direction of the first connecting rod. In the locked position, the locking member engages with the mating part, and in the unlocked position, the locking member disengages from the mating part.
9. The folding frame according to claim 1 or 8, characterized in that, The folding frame also includes an elastic element disposed between the locking member and the first connecting rod, the elastic element generating an elastic force that drives the locking member to move toward the locking position.
10. A children's product, characterized in that, The child equipment includes a folding frame as described in any one of claims 1 to 9, and the child equipment includes a child's bed.
