A height of the support post is identical to a height of the slat. The slat is located outside the support post, and a gap is arranged between the support post and the slat. The support post and the slat are arranged between the support base and the pivoting piece. The two long handrail tubes are arranged opposite to each other, and the two short handrail tubes are arranged opposite to each other. The long handrail tube or the short handrail tube is arranged between two adjacent pivoting pieces of the four support assemblies.

DETAILED DESCRIPTION OF THE EMBODIMENTS

(7) Referring to FIGS. 1 to 4, a playpen frame for an easy-to-install enclosure includes four support assemblies 1, two long handrail tubes 2, two short handrail tubes 3 and a bottom frame 4. The four support assemblies 1 are distributed at four corners, and each of the support assemblies 1 includes the support base 11, the support post 12, the slat 13 and the pivoting piece 14. The height of the support post 12 is identical to the height the slat 13. The slat 13 is located outside the support post 12, and the gap 15 is arranged between the support post 12 and the slat 13. The support post 12 and the slat 13 are arranged between the support base 11 and the pivoting piece 14. The two long handrail tubes 2 are arranged opposite to each other, and the two short handrail tubes 3 are also arranged opposite to each other. The long handrail tube 2 or the short handrail tube 3 is arranged between two adjacent pivoting pieces 14 of the four support assemblies 1. The bottom frame 4 is connected to the support bases 11 of the four support assemblies 1.

(8) Referring to FIGS. 1 to 6, the lateral cross section of the support post 12 is in an oval shape in a top view. The slat 13 is a circular arc slat with a radian adapted to the outer half periphery of the support post 12. The inner peripheral surface of the slat 13 extends inwards along a height direction to form a plurality of convex ribs 131, and the plurality of convex ribs 131 can support the enclosure. The top surface of the support base 11 is provided with the first slot 111 adapted to the bottom of the support post 12 and the second slot 112 adapted to the bottom of the slat 13. The third slot 141 adapted to the top of the support post 12 and the fourth slot 142 adapted to the top of the slat 13 are provided in the middle of the pivoting piece 14. The bottom and the top of the support post 12 are inserted into the first slot 111 and the third slot 141, respectively. The bottom and the top of the slat 13 are inserted into the second slot 112 and the fourth slot 142, respectively. The containing slot 113 is provided inside the support base 11, and the four corners of the bottom frame 4 are connected into the corresponding containing slots 113, respectively.

(9) Referring to FIG. 1, the two long handrail tubes 2 and the two short handrail tubes 3 are connected to the corresponding pivoting pieces 14 by known means, and the bottom frame 4 adopts a structure that is known by skilled artisans, which will not be repeated here.

(10) Referring to FIGS. 1 to 4, the design principle of the present invention is as follows: no second tube hole is required at the four corners of the enclosure matched with the present invention, but a hook and a loop of a hook-and-loop fastener are sewn on two side ends of the enclosure, respectively. When the long handrail tubes 2 and the short handrail tubes 3 are inserted into the first tube holes corresponding to the enclosure and are then fixed, one side end of the enclosure is sequentially passed through gaps between the support posts 12 and the slats 13 of the four support assemblies 1. Finally, the two side ends of the enclosure are connected through the hook-and-loop fastener to complete the installation of the enclosure.

(11) The above described are merely specific implementations of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes made to the present invention based on the concept of the present invention shall fall within the scope of protection of the present invention.
