Description

Child game bed

Technical Field

The utility model relates to a child play yard.

Background

Child play yards capable of being unfolded and folded in the prior art are available in a large number of types according to different folding schemes of mechanisms. Typically comprising a plurality of sets of side frames, a plurality of uprights, a foldable lower frame connected between lower ends of the plurality of uprights, each set of side frames being pivotally connected between upper ends of adjacent uprights.

A child game enclosure as disclosed in patent application publication number CN 210144293U, comprises a plurality of vertical rods, an upper frame and a lower frame. The lower frame comprises a center seat positioned in the middle part and a plurality of groups of bottom connecting rod groups connected between the center seat and corresponding lower frame corner joints, wherein the center seat comprises an upper center group and a lower center group which can relatively move up and down, and each group of bottom connecting rod groups and the upper center group and the lower center group and the upright rods form a deformable four-bar mechanism. The upper frame comprises a plurality of surrounding rod assemblies, each surrounding rod assembly comprises an intermediate member and two surrounding frame rods, and an upper frame locking device is arranged between the two surrounding frame rods and the intermediate member. In the folding process, the upper center group is lifted upwards to deform the four-bar mechanism, so that each upright rod is inclined, each group of two surrounding frame rods approaches to the middle member, a locking piece of the upper frame locking device is separated from the locking groove section, the upper frame locking device is unlocked, and the surrounding frames of the children game are folded and folded; when the child game frame is unfolded, the upper central group is pressed downwards, the four-bar mechanism deforms to outwards open the vertical bars, each group of surrounding frame rods are pulled open and flattened, the locking piece enters the locking groove section, and the upper frame locking device locks the whole child game surrounding frame at the unfolded position. In actual use, the child game surrounding frame has potential safety hazards. If the two surrounding frame rods in the same group are subjected to opposite extrusion external force, the two surrounding frame rods can slide relative to the middle member directly, so that the locking piece can withdraw from the locking groove section, and the upper frame locking device is unlocked. Although it is mentioned in this scheme that the damping protrusion is provided on the lower surface of the locking groove section for enhancing stability in locking, preventing the locking member from exiting the locking groove section in the unfolded position, in the actual use process, the locking groove section is slightly or becomes larger with long-term use abrasion due to precise matching of the respective sizes of the locking groove section, the damping protrusion and the locking member, and thus the damping protrusion cannot play a role in preventing the locking member from exiting the locking groove section in the unfolded position, so that the structure still has a safety hazard. And, the lower frame structure of this scheme is relatively complicated.
