[0003] The utility model provides a folding rod assembly for a game bed with a simple structure, the main purpose of which is to overcome the problem that the existing game bed rods have a relatively complex structure and are cumbersome to operate during folding.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A folding rod assembly for a play yard with a simple structure comprises an articulated joint and two upper surrounding rods, the two upper surrounding rods being arranged symmetrically on the left and right sides of the articulated joint. An opening is provided on the left and right sides of the articulated joint, a guide sleeve is hinged in the opening, one end of the upper surrounding rod passes through the guide sleeve, two groups of guide grooves are provided on the articulated joint, each group of guide grooves corresponds to an upper surrounding rod, each group of guide grooves consists of two guide grooves arranged front and back, each guide groove comprises an inclined groove and a transverse groove connected to the top of the inclined groove, a first shaft rod is passed through each group of guide grooves, and the first shaft rod passes through the upper surrounding rod.

[0006] Furthermore, the present invention further comprises two lower enclosure rods, which are symmetrically arranged on both sides, and one end of each lower enclosure rod is hinged in the opening.

[0007] Furthermore, a rod connector is provided at one end of each lower enclosure rod, and the rod connector is hinged in the opening. Two groups of elliptical holes are provided on the hinge joint, and each group of elliptical holes corresponds to a lower enclosure rod. Each group of elliptical holes is composed of two elliptical holes arranged front and back, and each group of elliptical holes is passed through a second shaft rod, and the second shaft rod passes through the rod connector and the lower enclosure rod.

[0008] Furthermore, a groove is provided at the end of the lower enclosure rod close to the hinge joint, and both side surfaces of the groove are inclined surfaces.

[0009] Furthermore, the articulated joint includes a front joint piece, a rear joint piece, and a top piece connected between the middle portion of the front joint piece and the middle portion of the rear joint piece.

[0010] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following advantages: the present invention has a novel structure and an ingenious design. When the playbed is in use, the two upper surrounding rods are in an unfolded state, and the first shaft rod is located in the transverse groove; when the playbed is folded, the first shaft rod will detach from the transverse groove and fall into the inclined groove. At this time, the hinge joint moves downward. As the hinge joint continues to descend, the first shaft rod moves toward the bottom of the inclined groove until the two upper surrounding rods are folded upward. The two upper surrounding rods can move along the guide sleeve during the folding process, making the folding of the playbed smoother. When the playbed is to be unfolded, the hinge joint is lifted. At this time, the two upper surrounding rods are unfolded, and the first shaft rod moves toward the top of the inclined groove until the first shaft rod enters the transverse groove. The present invention adopts a simpler structure to achieve the folding of the folding rod assembly. There is no need to press a button when folding, and the operation is more convenient.

[0015] Reference Figure 1 and Figure 2 A simple-structured play yard folding rod assembly includes an articulated joint 1 and two upper enclosure rods 2, the two upper enclosure rods 2 being symmetrically arranged. The left and right portions of the articulated joint 1 are each provided with an opening 3, within which a guide sleeve 4 is hingedly connected, through which one end of the upper enclosure rod 2 passes. The articulated joint 1 is provided with two sets of guide grooves 5, each set of guide grooves 5 corresponding to one upper enclosure rod 2. Each set of guide grooves 5 consists of two guide grooves 5 arranged front and back, each guide groove 5 including an inclined groove 51 and a transverse groove 52 connected to the top of the inclined groove 51. A first shaft rod 6 is passed through each set of guide grooves 5, which passes through the upper enclosure rod 2.

[0016] Reference Figure 1 and Figure 2 The present invention further comprises two lower enclosure rods 7, which are arranged symmetrically with respect to each other. One end of each lower enclosure rod 7 is hingedly connected to the opening 3. A rod connector 8 is provided at one end of each lower enclosure rod 7, which is hingedly connected to the opening 3. The hinge joint 3 is provided with two groups of elliptical holes 9, each group of elliptical holes 9 corresponding to one lower enclosure rod 7. Each group of elliptical holes 9 consists of two elliptical holes 9 arranged in a front-to-rear manner. Each group of elliptical holes 9 is penetrated by a second shaft rod 10, which passes through the shaft connector 8 and the lower enclosure rod 7. A groove 71 is provided at the end of the lower enclosure rod 7 near the hinge joint 3, and both sides of the groove 71 are inclined surfaces 72.

[0017] Reference Figure 1 and Figure 2 The articulated joint 1 comprises a front joint piece 11, a rear joint piece 12 and a top piece 13 connected between the middle portion of the front joint piece 11 and the middle portion of the rear joint piece 12. The guide groove 5 and the elliptical hole 9 are provided on both the front joint piece 11 and the rear joint piece 12.

[0018] Reference Figures 1 to 4 The design principle of the present invention is as follows: When the playbed is in use, the two upper enclosure bars 2 and the two lower enclosure bars 7 are both in the unfolded state, and the first shaft rod 6 is located in the transverse groove. When the playbed is folded, the hinge joint 3 moves downward, at which point the first shaft rod 6 disengages from the transverse groove 52 and falls into the inclined groove 51. The two upper enclosure bars 2 and the two lower enclosure bars 7 fold relative to the hinge joint 3. As the playbed folds, the hinge joint 3 continues to descend, and the first shaft rod 6 moves toward the bottom of the inclined groove 51 until the two upper enclosure bars 2 and the two lower enclosure bars 7 are completely folded upward. During the folding process, the two upper enclosure bars 2 can move along the guide sleeve 4, making the folding of the playbed more stable. When the playbed is to be unfolded, the hinge joint 3 is lifted, at which point the two upper enclosure bars 2 and the two lower enclosure bars 7 unfold, and the first shaft rod 6 moves toward the top of the inclined groove until the first shaft rod 6 enters the transverse groove 52. The lower enclosure rod 7 makes the playbed more stable, the elliptical hole 9 provides a movable space for the second shaft rod 10, and makes the lower enclosure rod 7 smoother in folding. The groove 71 makes the end of the lower enclosure rod 7 close to the hinge joint 3 less likely to break. At the same time, the groove 71 can also provide a space for the guide sleeve 4 after the upper enclosure rod 2 and the lower enclosure rod 7 are folded.

[0019] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
