Description

Technical Field

[0001] The invention relates to the field of household appliances, and in particular to a foldable fence for infants and young children. Background Art

[0002] A baby fence is a device that provides safety protection for babies between 6 months and 3 years old. When parents are unable to look after their babies all the time, the baby fence can enclose a safe area for the baby to move around, preventing the baby from crawling into dangerous areas such as the kitchen and stairwells, and avoiding accidents caused by contact with sharp objects, swallowing small objects, or falling from heights. Parents can put the baby in the fence and let them play by themselves, so that they have time to do other things, such as housework, rest, work, etc., which reduces the burden on parents to a certain extent and allows parents to take care of the baby more calmly.

[0003] Existing baby fences are generally of overall folding structure. When children need to move freely occasionally, the whole device must be dismantled or stored, which is inconvenient. In addition, modular fences are generally self-connected, which is not conducive to various combinations with structures in the family room to adapt to different children's growth environments. Summary of the invention

[0004] In order to make up for the above deficiencies, the present invention provides a foldable playpen for infants and young children that overcomes the above technical problems or at least partially solves the above problems.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A foldable fence for infants and young children comprises a column, a fence mechanism is provided on the side of the column, and the fence mechanism comprises:

[0007] An installation frame, wherein the top and the bottom of the side of the installation frame are provided with installation plates;

[0008] A first enclosure frame, wherein the first enclosure frame is connected to the mounting plate via a damping shaft, and a first straight slot plate is provided on a side of the bottom of the first enclosure frame close to the second enclosure frame;
