As shown in fig. 9-12, the present embodiment also provides two types of unitary construction for the child play enclosure. The following detailed description is provided.

The first embodiment of the upper frame of the game enclosure, as shown in fig. 1-3 and 9, includes four sets of enclosure rod assemblies 10 respectively disposed between four upper frame corner joints 13, each set of enclosure rod assemblies 10 includes two enclosure rod assemblies 11 located at the left and right sides and having one end respectively pivoted to the corresponding upper frame corner joint 13 about the top two-axis S2, and further includes an intermediate member 12 located between the other ends of the two enclosure rod assemblies 11.

The other end of each surround frame rod 11 is respectively connected with the corresponding side part of the middle member 12 in a manner of sliding left and right and rotating around the top shaft S1, when the upper frame 1 is in the unfolding position, the top shaft S1 of each surround frame rod assembly 10 is positioned below the horizontal connecting line of the two adjacent top shafts S2, and an upper frame locking device 100 is arranged between the middle member 12 and the other end of the two surround frame rods 11.

As shown in fig. 1 to 3, the other end of each of the frame surrounding rods 11 is provided with a guide groove 104 having a length direction identical to that of the frame surrounding rod 11, and a top shaft S1 is fixed to a corresponding side of the intermediate member 12, and the top shaft S1 is movably and rotatably inserted in the guide groove 104. The upper frame locking device 100 includes two latch grooves formed in the left and right sides of the middle member 12, and two latches 103 fixed to the other end of the surrounding frame rod 11. Each locking piece groove comprises a locking groove section 101 with the length extending along the left-right direction and an avoiding space 102 communicated with the locking groove section 101, in this embodiment, the avoiding space 102 is an arc-shaped groove, and in fact, the shape of the avoiding space 102 is not limited as long as the movement of the locking piece 103 is not affected.

The upper frame locking device 100 has a locking position and an unlocking position, when the upper frame locking device 100 is in the locking position, the two surrounding frame rods 11 are laid and unfolded relatively, the locking piece 103 is inserted into the locking groove section 101, the tension relatively far away between the two surrounding frame rods 11 enables the locking piece 103 to be stably inserted into the locking groove section 101, the locking groove section extends in the left-right direction, so that the surrounding frame rods 11 are limited to rotate around the top shaft S1, and the upper frame locking device 100 is stably in the locking position. When each set of two frame surrounding rods 11 approach relatively, the lock 103 is disengaged from the lock groove section 101 and moves into the avoiding space 102, so that the corresponding upper frame locking device 100 is switched from the locking position to the unlocking position, thereby allowing the middle member 12 to move downwards, the frame surrounding rods 11 can rotate around the top axis S1, and the two frame surrounding rods 11 are relatively merged and close together.

The guide groove 104 is located below the level of the lock groove section 101. When locked, the lock 103 is located above the horizontal plane of the top axis S1, and the locking is more secure.
