[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] The following is for reference. Figures 1-14 Description of a game bed frame 100 according to an embodiment of the present utility model.

[0020] Reference Figures 1-3 The playpen frame 100 according to an embodiment of the present invention includes: a frame 10 and a side support frame 20. The frame 10 defines an accommodating space 11 in which an infant can lie or sit. The frame 10 includes an upper rail 12, which is located at the top of the frame 10 and surrounds the accommodating space 11. The upper rail 12 is rectangular, and for example, it may include four sequentially connected rods. Adjacent rods may be detachably connected, and the rods may be hollow tubular structures, for example, the cross-section of the rods may be circular or annular.

[0021] There are at least two side support frames 20, each symmetrically connected to the frame 10 in pairs. For example, there are two side support frames 20, symmetrically connected to both sides of the frame 10 along a first direction (e.g., referring to direction e1 in the attached figure). The frame 10 can be rectangular, and the two side support frames 20 can be located on both sides of the length direction of the frame 10. Each side support frame 20 is connected to the frame 10, and each side support frame 20 is used to jointly support the frame 10.

[0022] Each side support frame 20 includes a column 21 and a leg 24. The column 21 extends vertically and can be a hollow structure. The frame 10 is connected to the columns 21 of the multiple side support frames 20. The columns 21 can be located on the outer periphery of the frame 10 and connected to the frame 10. The legs 24 are connected to the bottom of the columns 21 and can be used to support the frame on the ground. For example, the legs 24 can extend in a second direction (e.g., refer to direction e2 in the figure), which allows for a larger support area between the side support frame 20 and the ground, thereby improving the stability of the multiple side support frames 20 supporting the frame 10.

[0023] The upper end of the column 21 of each side support frame 20 is connected to the upper wall rod 12 by a connector 30. The number of connectors 30 is the same as the number of side support frames 20 and they correspond one-to-one. The upper end of each column 21 is connected to the upper wall rod 12 by a corresponding connector 30.

[0024] Each connector 30 includes a connecting cylinder 40, which is sleeved outside the upper surrounding rod 12, for example, on the outer periphery of the rod. The inner peripheral wall of the connecting cylinder 40 is provided with a first rib 41 and a support rib 42, which are spaced apart along the circumferential direction of the connecting cylinder 40. The first rib 41 and the support rib 42 can improve the structural strength of the connecting cylinder 40. Both the first rib 41 and the support rib 42 abut against the outer peripheral wall of the upper surrounding rod 12. The support rib 42 is located on the side of the connecting cylinder 40 away from the receiving space 11, which can enhance structural stability.

[0025] The first protruding rib 41 and the supporting rib 42 can both be integrally formed with the connecting cylinder 40. The connecting part 30 can be a plastic part, for example, the connecting part 30 can be an integral injection molded part.

[0026] When connecting the upper end of the mounting column 21 to the upper rod 12 via the connector 30, the upper rod 12 can be inserted through the connecting sleeve 40 of the connector 30. For example, the rod can be inserted through the connecting sleeve 40 of the connector 30. Since the inner circumferential wall of the connecting sleeve 40 is provided with a first rib 41 and a support rib 42, it makes the assembly of the connecting sleeve 40 and the upper rod 12 more convenient, reduces the frictional resistance during the assembly process, and reduces the assembly gap between the inner circumferential wall of the connecting sleeve 40 and the outer circumferential wall of the upper rod 12. By having the first rib 41 and the support rib 42 in the connecting sleeve 40 abut against the outer circumferential wall of the upper rod 12, the overall structural stability after assembly can be improved, thereby reducing the shaking of the play bed frame 100 and making the play bed frame 100 more stable.

[0027] Furthermore, by positioning the support rib 42 on the side of the connecting cylinder 40 away from the receiving space 11, the support rib 42 can reduce the assembly gap between the connecting cylinder 40 and the upper rod 12, while also constraining the outward deformation and expansion of the upper rod 12, thereby enhancing the stability of the upper rod 12 and better reducing the swaying of the game bed frame 100, resulting in higher stability of the game bed frame 100.

[0028] According to the embodiment of the present utility model, the game bed frame 100 is connected to the upper end of the upright 21 and the upper rod 12 of the frame 10 by a connector 30. The connecting cylinder 40 of the connector 30 is sleeved on the outer periphery of the connecting rod. A first rib 41 and a support rib 42 are protruding on the inner periphery of the connecting cylinder 40. The first rib 41 and the support rib 42 are spaced apart along the circumferential direction of the connecting cylinder 40 and abut against the outer periphery of the upper rod 12. This can reduce the assembly gap between the connecting cylinder 40 of the connector 30 and the upper rod 12, thereby reducing the shaking of the game bed frame 100 and making the game bed frame 100 more stable.

[0029] In some embodiments, refer to Figures 6-11 Along the radial direction of the upper frame 12, the support rib 42 is located diagonally below the upper frame 12. By positioning the support rib 42 diagonally below the upper frame 12, better support can be provided for the upper frame 12, and the outward deformation and expansion of the upper frame 12 can be restrained. This also enhances the stability of the upper frame 12 and reduces the swaying of the play bed frame 100, resulting in higher stability of the play bed frame 100.

[0030] In some embodiments, refer to Figures 6-11 The support rib 42 extends along the axial direction of the connecting cylinder 40. For example, both ends of the support rib 42 in the length direction extend along the axial direction of the connecting cylinder 40 to both sides of the axial direction of the connecting cylinder 40. By making the support rib 42 extend along the axial direction of the connecting cylinder 40, the contact area between the support rib 42 and the connecting cylinder 40 can be further increased, improving the support stability of the support rib 42 for the upper frame rod 12, and also improving the structural strength of the connecting cylinder 40, thereby making the structure more stable and better reducing the swaying of the play bed frame 100.

[0031] In some embodiments, refer to Figures 6-11 The first rib 41 extends along the axial direction of the connecting cylinder 40. For example, both ends of the first rib 41 in the length direction extend along the axial direction of the connecting cylinder 40 to both sides of the axial direction of the connecting cylinder 40, respectively. By making the first rib 41 extend along the axial direction of the connecting cylinder 40, the contact area between the first rib 41 and the connecting cylinder 40 can be further increased, and the structural strength of the connecting cylinder 40 can also be improved, thereby making the structure more stable and better reducing the swaying of the play bed frame 100.

[0032] In some embodiments, refer to Figures 6-11 Both the support rib 42 and the first rib 41 extend along the axial direction of the connecting cylinder 40. This can further increase the contact area between the support rib 42 and the first rib 41 and the connecting cylinder 40, improve the support stability of the support rib 42 for the upper frame rod 12, and also improve the structural strength of the connecting cylinder 40, thereby making the structure more stable and better reducing the swaying of the game bed frame 100.

[0033] In some embodiments, refer to Figures 6-11 There are multiple first protruding ribs 41, which are spaced apart along the circumferential direction of the connecting cylinder 40. A support rib 42 is located between two of the first protruding ribs 41 in the circumferential direction of the connecting cylinder 40. By setting multiple first protruding ribs 41, the contact area between the connecting cylinder 40 and the upper surrounding rod 12 can be increased, the assembly gap between the connecting cylinder 40 and the upper surrounding rod 12 can be reduced, the structure can be made more stable, and the shaking of the play bed frame 100 can be reduced.

[0034] For example, there are six first ribs 41, and the six first ribs 41 are arranged at intervals along the circumference of the connecting cylinder 40.

[0035] For example, the support ribs 42 and multiple first ribs 41 are evenly spaced in the circumferential direction of the connecting cylinder 40.

[0036] In some embodiments, refer to Figures 6-11 The support rib 42 includes a first support rib 421 and a second support rib 422 arranged at an angle, for example, the angle between the first support rib 421 and the second support rib 422 can be 80° to 110°, for example, the first support rib 421 and the second support rib 422 are arranged perpendicularly. For example, the support rib 42 extends along the axial direction of the connecting cylinder 40, and the cross-section of the support rib 42 can be a T-shaped structure, that is, the cross-section of the support rib 42 is a T-shaped section, the cross-section of the support rib 42 is perpendicular to the axial direction of the connecting cylinder 40, the vertical side of the T-shaped section is the first support rib 421, and the horizontal side of the T-shaped section is the second support rib 422.

[0037] The first end of the first support rib 421 is connected to the inner peripheral wall of the connecting cylinder 40, and the second end of the first support rib 421 extends toward the upper support rod 12 and is connected to the second support rib 422. The extension direction of the first support rib 421 from the first end to the second end can be along the radial direction of the connecting cylinder 40. The second support rib 422 abuts against the outer peripheral wall of the upper support rod 12. By including the first support rib 421 and the second support rib 422 arranged at an angle, the cross-section of the support rib 42 can be T-shaped, and the second support rib 422 abuts against the outer peripheral wall of the upper support rod 12, the contact area between the support rib 42 and the connecting cylinder 40 can be increased, improving the stability of the support rib 42 in supporting the upper support rod 12, which helps to reduce the swaying of the play bed frame 100.

[0038] The cross-section of the upper rod 12 can be circular or annular, and the side of the second support rib 422 facing the connecting cylinder 40 can be arc-shaped, so as to match the outer circumference shape of the upper rod 12, thereby supporting the upper rod 12 more stably and reducing the swaying of the play bed frame 100.

[0039] In some embodiments, refer to Figures 6-11 The second end of the first support rib 421 extends in the same straight line as the radial direction of the upper support rod 12. For example, the first support rib 421 extends obliquely upward in the direction from the first end to the second end. By making the extension direction of the second end of the first support rib 421 aligned with the radial direction of the upper support rod 12, the support rib 42 can provide stable support for the upper support rod 12 and constrain the outward deformation and expansion of the upper support rod 12. This can also better enhance the stability of the upper support rod 12 and better reduce the swaying of the play bed frame 100, resulting in higher stability of the play bed frame 100.

[0040] In some embodiments, refer to Figures 6-11 Multiple support ribs 423 are formed on the side of the second support rib 422 facing the upper rod 12. The multiple support ribs 423 are spaced apart along the circumferential direction of the connecting cylinder 40, and the multiple support ribs 423 abut against the outer peripheral wall of the upper rod 12. By forming multiple support ribs 423 on the side of the second support rib 422 facing the upper rod 12, and by having multiple support ribs 423 abut against the outer peripheral wall of the upper rod 12, the assembly difficulty between the connecting cylinder 40 and the upper rod 12 can be reduced, and the assembly gap between the two can be further reduced. In addition, the multiple support ribs 423 can provide more stable support for the upper rod 12, which can better reduce the swaying of the play bed frame 100, making the play bed frame 100 more stable.

[0041] For example, two support ribs 423 are formed on the side of the second support rib 422 facing the upper surrounding rod 12. The two support ribs 423 can be located at both ends of the width direction of the second support rib 422 and are spaced apart. The second support rib 422 can extend along the axial direction of the connecting cylinder 40. The width direction of the second support rib 422 can be perpendicular to the axial direction of the connecting cylinder 40. The width direction of the second support rib 422 can extend along the circumference of the connecting cylinder 40.

[0042] In some embodiments, refer to Figures 8-14The top of the upright 21 has a insertion cavity 22. The connector 30 includes an insertion part 50, which is connected to the lower side of the connecting cylinder 40 and inserted downward into the insertion cavity 22. By inserting the insertion part 50 of the connector 30 downward into the insertion cavity 22 formed at the top of the upright 21, the connection and fixation between the connector 30 and the upright 21 can be facilitated. This also allows for a larger contact area between the connector 30 and the upright 21, improving the stability of the connection between the upright 21 and the connector 30. This, in turn, improves the stability of the connection between the upper end of the upright 21 and the upper frame 12, better reducing the swaying of the play bed frame 100 and resulting in higher stability of the play bed frame 100.

[0043] The sidewall of the insertion part 50 is provided with a second protruding rib 51 and / or a third protruding rib 52, which abut against the inner wall of the insertion cavity 22. The provision of a second protruding rib 51 and / or a third protruding rib 52 on the sidewall of the insertion part 50 means that the sidewall of the insertion part 50 has a second protruding rib 51, or a third protruding rib 52, or both. By providing a second protruding rib 51 and / or a third protruding rib 52 on the sidewall of the insertion part 50, the second protruding rib 51 and / or the third protruding rib 52 located on the side can cooperate with the inner wall of the cavity of the column 21. This reduces the assembly gap when the insertion part 50 of the connector 30 and the column 21 are engaged, thus better reducing the swaying of the play bed frame 100 and improving the stability of the play bed frame 100.

[0044] In some embodiments, refer to Figures 1-14 The side wall of the insertion part 50 is provided with a second protruding rib 51. The second protruding rib 51 is located on opposite sides of the insertion part 50 along the second direction, and the second protruding rib 51 extends in the vertical direction. The second direction and the vertical direction intersect each other, for example, the second direction is perpendicular to the vertical direction. This can enhance the stability of the assembly between the connector 30 and the column 21 in the second direction, thereby making the overall stability of the play bed frame 100 higher and reducing the shaking of the play bed frame 100.

[0045] In some embodiments, refer to Figures 3-5 The second rib 51 is provided with a side protrusion 53, which can extend in the vertical direction and can be close to the middle of the second rib 51 in the vertical direction. The side protrusion 53 on the second rib 51 can ensure that the insertion part 50 can abut against the inside of the column 21 in the second direction, thereby improving the structural stability and reducing the shaking of the play bed frame 100.

[0046] Furthermore, the insertion part 50 is provided with a through hole 54 at the position corresponding to the side protrusion 53. In the second direction, the through hole 54 on the same side is located on the side of the corresponding side protrusion 53 near the middle of the insertion part 50, and the through hole 54 penetrates the insertion part 50 along the first direction. The first direction, the second direction, and the vertical direction intersect each other, for example, the first direction, the second direction, and the vertical direction are perpendicular to each other. By providing a through hole 54 near the side protrusion 53, the elastic deformation capability of the insertion part near the side protrusion 53 can be increased, making it easier for the insertion part 50 to be assembled into the insertion cavity 22 at the upper end of the column 21 through elastic deformation. After assembly, the insertion part 50 and the insertion cavity 22 can achieve an interference fit in the second direction, improving the stability of the connection between the insertion part 50 and the column 21, and reducing the assembly gap between the insertion part 50 and the column 21, which can reduce the shaking of the play bed frame 100.

[0047] In some embodiments, refer to Figures 8-9 The side wall of the insertion portion 50 is provided with a third protruding rib 52, which is located on at least one side of the insertion portion 50 along the first direction. For example, the third protruding rib 52 can be located on one side of the insertion portion 50 along the first direction, or it can be located on both sides of the insertion portion 50 along the first direction. By providing the third protruding rib 52 on the side wall of the insertion portion 50 and making the third protruding rib 52 located on at least one side of the insertion portion 50 along the first direction, the stability of the assembly between the connector 30 and the column 21 in the first direction can be enhanced, thereby making the overall stability of the play bed frame 100 higher and reducing the swaying of the play bed frame 100.

[0048] In some embodiments, refer to Figures 8-12 In the first direction, the plug-in part 50 is provided with an elastic buckle 55 and a third protruding rib 52 on the side near the receiving space 11, and the inner wall of the plug-in cavity 22 is provided with a locking hole 23, into which the elastic buckle 55 is engaged. In this way, when the plug-in part 50 is inserted downward into the plug-in cavity 22 at the upper end of the column 21, the elastic buckle 55 on the plug-in part 50 can be engaged into the locking hole 23 of the column 21, further improving the stability and reliability of the connection between the connector 30 and the column 21.

[0049] The third rib 52 is located below the elastic buckle 55 and extends obliquely in the vertical direction. By positioning the third rib 52 below the elastic buckle 55 and extending obliquely in the vertical direction, the contact area between the lower end of the insertion part 50 and the column 21 can be increased, making the overall fit between the insertion part 50 and the column 21 more stable. Furthermore, since the third rib 52 and the elastic buckle 55 are located on the same side of the insertion part 50, the third rib 52 enhances the stability of the assembly between the connector 30 and the column 21 in the first direction. This enhances the stability of the engagement between the elastic buckle 55 and the locking hole 23 on the column 21, making the assembly structure more stable and reliable. This results in higher overall stability of the play bed frame 100 and reduces the shaking of the play bed frame 100.
