[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] An embodiment of the present application discloses a connecting joint.

[0039] Reference Figure 1 and Figure 2 The connecting joint includes a connecting seat 1, two connecting plates 2 and two connecting rod assemblies 3. The connecting seat 1 is hollow and has two first movable grooves 11. The two first movable grooves 11 are penetrated and inclined. At the same time, the two first movable grooves 11 are spaced and symmetrically arranged along the length direction of the connecting seat 1, so that the two first movable grooves 11 are in an "eight" shape.

[0040] The two connecting pieces 2 are L-shaped and are spaced apart within the connector base 1 and symmetrically arranged along the length of the connector base 1, forming a herringbone shape. The upper ends of the two connecting pieces 2 are slidably connected to the connector base 1 along the width of the connector base 1 and are rotatably connected to the connector base 1. At the same time, the lower ends of the two connecting pieces 2 are rotatably connected to the connector base 1.

[0041] The two connecting rod assemblies 3 are spaced apart and arranged opposite to each other along the length direction of the connecting base 1, and the two connecting rod assemblies 3 operate synchronously. Specifically, the connecting rod assembly 3 includes a first connecting rod 31, a first connecting shaft 32, a second connecting shaft 33, and a second connecting rod 34. The first connecting rod 31 is a round rod, and one end of the first connecting rod 31 is provided with a movable hole 311 and a clearance groove 312. The movable hole 311 is arranged in a circular shape. The first connecting shaft 32 is a rivet and is fixedly connected to the connecting base 1. The first connecting shaft 32 is movably inserted into the movable hole 311 and the first movable groove 11, that is, the first connecting shaft 32 is rotatably connected to the movable hole 311 and is movable limited in the first movable groove 11, so that one end of the first connecting rod 31 is rotatably connected to the first connecting shaft 32 and slides along the first movable groove 11.

[0042] A clearance groove 312 is provided along the length of the first connecting rod 31. The second connecting shaft 33 is also a rivet and is fixedly connected to the connecting base 1. The second connecting shaft 33 is movably provided through the clearance groove 312 and the connecting base 1, so that the second connecting shaft 33 is movably restrained in the clearance groove 312 and is rotationally connected to the connecting base 1. One end of the second connecting rod 34 is located in the connecting base 1. The second connecting rod 34 is rotationally connected to the end of the connecting plate 2 that is rotationally connected to the connecting base 1 and is rotationally connected to the connecting base 1.

[0043] Reference Figure 2 and Figure 3 In actual use, the user presses down on the connecting base 1, causing the first connecting rod 31 to slide downward along the first movable groove 11 via the first connecting shaft 32 and slide along the clearance groove 312 via the second connecting shaft 33, thereby rotating the first connecting rod 31. At the same time, one end of the connecting plate 2 slides downward along the width of the connecting base 1 and rotates, causing the second connecting rod 34 to be rotatably connected to the connecting base 1, thereby rotating the second connecting rod 34 and folding the crib. Since the connecting plate 2 is located inside the connecting base 1, it can minimize the risk of hand pinching, thereby effectively improving the safety of the crib. It should be noted that one end of the second connecting rod 34 is provided with a plastic tube sleeve (not marked in the figure) to minimize the risk of the second connecting rod 34 scratching the fabric during rotation.

[0044] Reference Figure 2 and Figure 3 In some embodiments, the connecting joint also includes a limiting shaft 4, and a second movable groove 12 is opened on one side of the connecting seat 1 along its own width direction. The limiting shaft 4 is movably passed through one end of the two connecting pieces 2 and the second movable groove 12, that is, one end of the two connecting pieces 2 is rotatably connected to the limiting shaft 4, and the limiting shaft 4 slides along the second movable groove 12, so that the connecting piece 2 can be slidably connected to the connecting seat 1 along the width direction of the connecting seat 1 and rotatably connected to the connecting seat 1. The structure is simple and the operation is stable.

[0045] In some embodiments, the limiting shaft 4 is a rivet, one end of the limiting shaft 4 abuts against the outer side of the connecting seat 1, and the other end abuts against one of the connecting plates 2, so that the two connecting plates 2 are abutted and limited between the connecting seat 1 and the limiting shaft 4. This can effectively shorten the length of the limiting shaft 4, making the length of the limiting shaft 4 smaller, so that the production cost of the limiting shaft 4 is lower, thereby reducing the production cost of the connecting joint.

[0046] Reference Figure 1 and Figure 2 In some embodiments, a mounting groove 13 is provided on a side of the connecting seat 1 away from the second movable groove 12. The mounting groove 13 is located at the lower end of the second movable groove 12 and extends to the lower wall of the connecting seat 1. When installing the limit shaft 4, the mounting groove 13 can allow the limit shaft 4 to make way, thereby facilitating the installation of the limit shaft 4 in the connecting seat 1.

[0047] Reference Figure 3 and Figure 4 In some embodiments, the first movable groove 11 includes a fastening portion 111 and a movable portion 112. The movable portion 112 is arranged at an angle, and the fastening portion 111 is connected to the upper end of the movable portion 112, and the fastening portion 111 is arranged along the length direction of the connecting seat 1. When the first connecting shaft 32 is movable and limited to the fastening portion 111, the first connecting rod 31 can be prevented from rotating as much as possible, and the baby crib can be prevented from folding during normal use as much as possible, so as to improve the safety of the baby crib.

[0048] In some embodiments, the connecting base 1 is provided with two third movable grooves 14 arranged along the length direction of the connecting base 1. The two third movable grooves 14 are arranged through and are respectively located on the side away from each other of the two first movable grooves 11. At the same time, the second connecting shaft 33 is movably passed through the third movable groove 14, so that the rotation of the first connecting rod 31 is more flexible to ensure the stability of the folding of the baby crib.

[0049] In some embodiments, rounded corners 15 are provided on both sides of the upper end of the connecting base 1 to make the upper end of the connecting base 1 smooth, thereby minimizing the risk of scratching the user and further improving the safety of the baby crib.

[0050] The working principle of this embodiment is as follows: In actual use, when the user presses down on the connecting base 1, the first connecting rod 31 slides downward along the first movable groove 11 via the first connecting shaft 32 and slides along the clearance groove 312 via the second connecting shaft 33, thereby rotating the first connecting rod 31. At the same time, one end of the connecting piece 2 slides downward along the width direction of the connecting base 1 and rotates, causing the second connecting rod 34 to be rotatably connected to the connecting base 1, thereby rotating the second connecting rod 34 and folding the crib. In particular, because the connecting piece 2 is located inside the connecting base 1, it can minimize the possibility of pinching the hands, thereby effectively improving the safety of the crib.

[0051] The embodiment of the present application also discloses a baby crib.

[0052] Reference Figure 5 The crib includes four connecting members 5 and the four connecting joints described in the above embodiment. Two connecting joints are connected to the corresponding first connecting rod 31 and second connecting rod 34 through the connecting member 5.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
