The connecting seat is fixedly connected inside the hinge joint. The two first iron sheets are connected to the connecting seat front and back. The first iron sheet is provided with two first guiding grooves that are symmetric left and right, and the two first guiding grooves are in a shape similar to an "eight". The left and right ends of the top of the first iron sheet are provided with extension parts in a direction away from the connecting seat. The left and right end faces of the first iron sheet are inclined surfaces, and the inclined surfaces are parallel to the first guiding grooves. An arc-shaped groove is formed between the bottom of the extension part and the top of the inclined surface. The ends of the two upper railings close to the hinge joint are connected with a second iron sheet. The thickness of the second iron sheet is adapted to the distance between the two first iron sheets. The second iron sheet is located between the two first iron sheets. The end of the hinge joint away from the connecting seat is provided with two second guiding grooves that are symmetric front and back and arranged horizontally. The arc-shaped groove is aligned with one end of the second guiding groove close to the first iron sheet. The first iron sheet is provided with a first guiding pin and a second guiding pin. The first guiding pin and the second guiding pin respectively pass through the first guiding groove and the second guiding groove. When the upper railing is unfolded, the first guiding pin is stuck at the top of the first guiding groove, and the second guiding pin is stuck inside the arc-shaped groove. The ends of the two lower railings close to the hinge joint are hinged to the hinge joint.

[0007] Further, the top of the first guiding groove is an arc-shaped clamping groove.

[0008] Further, the connecting seat is in a shape similar to a triangle. The connecting seat is connected inside the hinge joint through three first connecting pins. The three first connecting pins are arranged in a triangular pattern, and the three first connecting pins pass through the first iron sheet.

[0009] Further, the connecting seat is provided with two installation grooves arranged front and back. The tops of the two installation grooves are of an open structure. The middle part of the first iron sheet is located inside the installation groove.

[0019] Refer to Figures 1 to 3A play yard fence assembly with better stability includes a hinge joint 1, two upper fences 2, two lower fences 3, a connecting seat 4, and two first iron sheets 5. The connecting seat 4 is fixedly connected to the hinge joint 1, and the two first iron sheets 5 are connected to the connecting seat 4 frontally and rearwardly. The first iron sheet 5 is provided with two first guide grooves 51 symmetrical on the left and right sides. The two first guide grooves 51 are in an "eight" shape. The top of the first guide groove 51 is an arc-shaped slot 52. The left and right ends of the top of the first iron sheet 5 are provided with extensions 53 in a direction away from the connecting seat 4. The left and right end faces of the first iron sheet 5 are both inclined surfaces 54. The inclined surfaces 54 are parallel to the first guide grooves 51. An arc-shaped slot 55 is formed between the bottom of the extension 53 and the top of the inclined surface 54. The ends of the two upper enclosure rods 2 near the articulated joint 1 are connected to a second iron sheet 6. The thickness of the second iron sheet 6 matches the distance between the two first iron sheets 5. The second iron sheet 6 is located between the two first iron sheets 5. The end of the articulated joint 1 away from the connecting seat 4 is provided with two second guide grooves 11 that are symmetrical in front and back and arranged laterally. The arc-shaped groove 53 is directly opposite to the end of the second guide groove 11 near the first iron sheet 5. The first iron sheet 5 is provided with a first guide pin 7 and a second guide pin 8. The first guide pin 7 and the second guide pin 8 pass through the first guide groove 51 and the second guide groove 11 respectively. When the upper enclosure rod 2 is unfolded, the first guide pin 7 is stuck on the arc-shaped slot 52 of the first guide slot 51, and the second guide pin 8 is stuck in the arc-shaped slot 52. The ends of the two lower enclosure rods 3 near the articulated joint 1 are hinged to the articulated joint 1.

[0020] Reference Figures 1 to 3 The thickness of the second iron sheet 6 matches the distance between the two first iron sheets 5, and the second iron sheet 6 is located between the two first iron sheets 5. This structural design prevents the second iron sheet 6 from shaking, making the upper enclosure 2 more stable during deployment and folding. When deployed, the first guide pin 7 engages with the arcuate slot 52 of the first guide groove 51, and the second guide pin 8 engages within the arcuate slot 52. This connects the upper enclosure 2 to both the two first iron sheets 5 and the hinge joint 1, thereby improving the connection strength of the upper enclosure 2. Furthermore, when the playpen is covered with a cloth cover, the contact area between the second iron sheet 6 and the cloth cover is smaller, making it less likely for the second iron sheet 6 to get caught in the cloth cover when the playpen is folded.

[0021] Reference Figures 1 to 3 The connecting base 4 is triangular in shape and is connected to the hinge joint 1 via three first connecting pins 9. The three first connecting pins 9 are arranged at three points and pass through the first iron plate 5. The connecting base 4 is provided with two mounting slots 41 arranged in the front and rear. The tops of the two mounting slots 41 are open structures, and the middle of the first iron plate 5 is located within the mounting slots 41.

[0022] Reference Figures 1 to 3 The end of the upper enclosure rod 2 close to the hinge joint 1 is connected to an iron sheet connecting rod 10, and the second iron sheet 6 is connected to the iron sheet connecting rod 10. Specifically, the iron sheet connecting rod 10 is provided with a stopper 12 and a clamping portion 13 at one end close to the first iron sheet 5, and the end of the upper enclosure rod 2 close to the hinge joint 1 is provided with a clamping slot 21. The iron sheet connecting rod 10 is located in the upper enclosure rod 2, the stopper 12 is in conflict with the end face of the upper enclosure rod 2, and the clamping portion 13 is located in the clamping slot 21. The iron sheet connecting rod 10 is provided with a slot 14, and the half of the second iron sheet 6 away from the first iron sheet 5 is inserted into the slot 14. The iron sheet connecting rod 10 is connected to the upper enclosure rod 2 through a second connecting pin 15, and the second connecting pin 15 passes through the second iron sheet 6. The height of the half of the second iron sheet 6 away from the first iron sheet 5 is smaller than the height of the half of the second iron sheet 6 close to the first iron sheet 5, so that the second iron sheet 6 has a step surface 61. When the half of the second iron sheet 6 away from the first iron sheet 5 is inserted into place from the slot 14, the step surface 61 conflicts with the blocking portion 12.

[0023] Reference Figure 1 and Figure 4 The present invention also discloses a play yard that utilizes the aforementioned play yard rod assembly, comprising a foldable base 16, four upper connectors 17, four vertical rods 18, four lower connectors 19, four connecting rods 20, and four sets of the play yard rod assembly. The connecting rods 20 are connected between the foldable base 16 and one of the lower connectors 19, the vertical rods 18 are connected between one of the upper connectors 17 and one of the lower connectors 19, and the play yard rod assembly is hinged between two adjacent upper connectors 17. The foldable base 16 is a conventional structure and will not be described in detail herein. When lifted upward, it drives the four connecting rods 20 to fold upward.

[0024] Reference Figures 1 to 4, the design principle of the present utility model is as follows: When the playpen is unfolded and in use, the first guide pin 7 is engaged with the arc-shaped card slot 52 of the first guide groove 51, and the second guide pin 8 is engaged within the arc-shaped groove 52. When the playpen needs to be folded, the folding base 16 is lifted upward. The folding base 16 simultaneously drives the four connecting rods 20 to perform a folding action upward, thereby pulling the four lower connectors 19 to converge towards the folding base 16. At this time, the lower parts of the four vertical rods 18 are pulled inward due to the acting force. Since the length of the lower surrounding rod 3 remains unchanged all the time, when the lower parts of the vertical rods 18 are pulled inward, the upper parts of the vertical rods 18 will expand outward. The upper parts of the vertical rods 18 will pull the upper surrounding rod 2 to move outward through the upper connector 17. When the upper surrounding rod 2 moves outward, it drives the first guide pin 7 to separate from the arc-shaped card slot 52 and gradually move outward and downward along the first guide groove 51, thereby starting to fold the upper surrounding rod 2. While the first guide pin 7 is moving outward and downward, the second guide pin 8 also moves outward along the second guide groove 11. At the same time, the hinge joint 1 gradually descends under the action of the inward convergence of the vertical rod 18. As the hinge joint 1 gradually descends, the hinge end of the lower surrounding rod 3 relative to the hinge joint 1 rotates and folds.

[0025] The above is only the specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive modification made to the present utility model using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
