The end of the lower surrounding pipe 1 is provided with a lower joint 11, the end of the upper surrounding pipe 2 is provided with an upper joint 21, the lower joint 11 and the upper joint 21 are connected through a hinge shaft 10 and can rotate relative to each other, wherein the rotation of the lower joint 11 and the upper joint 21 can realize the folding or unfolding of the lower surrounding pipe 1 and the upper surrounding pipe 2 to form a sleeping basket frame.

[0036] The lower joint 11 is provided with a locking assembly 3, the locking assembly 3 includes a hook piece 31 connected elastically, the outer joint 4 is fixedly arranged on the outer joint 21 through a connecting shaft 22, the hook piece 31 and the connecting shaft 22 are matched to limit or separate to realize the locking or unlocking between the lower joint 11 and the upper joint 21.

[0037] Specifically, in the locking state, the hook piece 31 and the connecting shaft 22 are matched and cooperated with the elastic structure in the locking assembly 3 to realize double guarantee, which prevents the sleeping basket from being folded accidentally, and the hook piece 31 and the connecting shaft 22 can be separated to realize the relative folding and folding of the lower joint 11 and the upper joint 21.

[0038] In the embodiment, the locking assembly 3 includes a lock column 32 matched with the hook piece 31, the lock column 32 vertically slides into the lower joint 11, the lower joint 11 is formed with a groove hole 111 matched with the lock column 32, and the top end of the lock column 32 extends out of the groove hole 111 and the bottom end is provided with a spring column 33.

[0039] The lock column 32 is used to control the cooperation or separation of the hook piece 31 and the connecting shaft 22.

[0040] The lock column 32 and the spring column 33 matched with the lock column 32 are hidden in the lower joint 11, which can ensure the stability of the structure of the lock column 32 and avoid the complexity of the appearance structure.

[0041] Specifically, by pressing the lock column 32, the lock column 32 acts on the hook piece 31 and makes the hook piece 31 separate from the connecting shaft 22, and when resetting, the lock column 32 is also pressed to make the hook piece 31 hook the connecting shaft 22 and realize locking through the restoring force of the spring column 33.

[0042] In the embodiment, the hook piece 31 includes a hook part 311 matched with the connecting shaft 22 and a connecting part 312 hinged with the lower joint 11, the side close to the hook part 311 of the lower joint 11 is provided with a straight groove 112 communicated with the groove hole 111, the lock column 32 is formed with an action hole 321 opposite to the straight groove 112 and allowing the connecting part 312 to pass through, and the connecting part 312 passes through the straight groove 112 and the action hole 321 in sequence and is hingedly connected with the inside of the lower joint 11 through a rivet.

[0043] The side of the upper joint 21 opposite to the hook piece 31 is provided with a long slot 23 opposite to the connecting shaft 22, and the length of the long slot 23 and the straight slot 112 is greater than the width of the connecting part 312.

[0044] The length of the long slot 23 and the straight slot 112 is limited to provide a movable and swingable allowance for the hook piece 31 to avoid interference with the swing of the hook piece 31.

[0045] In the embodiment, the side of the upper joint 21 away from the lower joint 11 is provided with a boss 24, and the boss 24 is formed with an avoiding slot 241 corresponding to the hinge shaft 10.

[0046] Through the setting of the boss 24 and the avoiding slot 241, the end of the hinge shaft 10 is prevented from being interfered by the outer joint 4 outside the upper joint 21, and the flexibility of rotation between the upper joint 21 and the lower joint 11 is improved.

[0047] In the embodiment, the side of the upper joint 21 opposite to the outer joint 4 is provided with a positioning column 25 extending outwardly from the boss 24, and the side of the outer joint 4 opposite to the upper joint 21 is provided with a positioning sleeve 41 corresponding to the positioning column 25.

[0048] The center of the positioning column 25 is provided with a through hole 251 allowing the connecting shaft 22 to pass through, and the end of the connecting shaft 22 close to the outer joint 4 extends into the positioning sleeve 41 and is fixedly connected with the bottom surface of the positioning sleeve 41.

[0049] The positioning column 25 and the positioning sleeve 41 form a precise guide structure, ensuring that the assembly position of the outer joint 4 and the upper joint 21 is completely matched.
