In some embodiments, in order to limit the rotation range of the main beam 22 relative to the hinge seat 23, a limit structure for limiting the swing angle of the main beam 22 is provided between the hinge seat 23 and the main beam 22, so that the main beam 22 can be quickly switched to a predetermined position, in combination with fig. 10, and thus the first end 22a of the main beam 22 and the connecting seat 21 can be conveniently aligned and connected during assembly, and in combination with fig. 11, the main beam 22 can be conveniently swung towards the middle of the second side frame 10b instead of being swung towards the outer side of the second side frame 10b during folding of the beam body 20, thereby improving the assembly efficiency. The limiting structure has different implementation modes.

The first limiting structure is realized in the following mode: referring to fig. 10, the hinge base 23 has a rotation-direction limiting surface 234, and in conjunction with fig. 9, the limiting structure includes a first limiting surface 224 and a second limiting surface 225, the first limiting surface 224 is formed on an end surface of the second end 22b of the main beam 22, and the end surface is an axial end surface of the main beam 22 at the second end 22 b. The second limiting surface 225 is formed on a side surface of the second end 22b of the main beam 22, and a predetermined angle is formed between the first limiting surface 224 and the second limiting surface 225. Referring to fig. 10, when the beam body 20 is disposed between the first side frame 10a and the second side frame 10b in a straight state, the first limiting surface 224 is disposed opposite to the steering limiting surface 234. Referring to fig. 9 and 11, when the main beam 22 is stacked on the second side frame 10b, the second constraining surface 225 is disposed opposite to the steering constraining surface 234.

Referring to fig. 9, when the first limiting surface 224 and the second limiting surface 225 are disposed at the second end 22b of the main beam 22, the first limiting surface 224 and the second limiting surface 225 are disposed at 90 °, and the side of the main beam 22 parallel to the rotation axis of the main beam 22 is set as the second limiting surface 225, so that the rotation angle of the main beam 22 relative to the hinge seat 23 is in the range of 0 ° to 90 °. In addition, the range of angles of rotation of the main beam 22 relative to the hinge base 23 may be set to other ranges of values as desired.

In some embodiments, referring to fig. 10, in order to improve the connection reliability between the main beam 22 and the connection seat 21 and between the main beam 22 and the hinge seat 23, in the same beam body 20, when the first end 22a of the main beam 22 is mounted to the connection seat 21, the first end 22a of the main beam 22 and the connection seat 21 can be connected by a first locking structure 25a, and the second end 22b of the main beam 22 and the hinge seat 23 can be connected by a second locking structure 25 b. After the position of the main beam 22 is adjusted, the two ends of the main beam 22 are respectively fixed on the connecting seat 21 and the hinged seat 23 through the locking structures, so that the connection reliability is improved, and the possibility of decomposition caused by external force on the framework 100 is reduced. Wherein the first locking structure 25a and the second locking structure 25b may be fasteners, snap structures, or the like. One or more locking structures are arranged at the connecting position of the two structural members, so that the connecting reliability of the two structural members can be changed. For example, two fasteners are provided between the first end 22a of the main beam 22 and the connecting seat 21, so that the first end 22a of the main beam 22 and the connecting seat 21 are reliably connected.
