The connection joint 13 includes an upper rotating base 131 and a lower rotating base 132. A connection rod 1311 is disposed on the upper rotating base 131 and/or the lower rotating base 132, the cross rod 11 is in a shape of a cylinder and sleeved on the connection rod 1311, and the cross rod 11 is detachably connected to the connection rod 1311. A central part of the upper rotating base 131 and a central part of the lower rotating base 132 are each provided with a through-hole, a locking pin 14 penetrates through the through-hole, and the locking pin 14 is connected to the vertical rod 12 after penetrating through the through-hole.

[0038] Preferably, in this embodiment, the locking pin 14 is a screw. The locking pin 14 is connected to the vertical rod 12 in a threaded manner after penetrating through the through-hole of the upper rotating base 131 and the through-hole of the lower rotating base 132. That is, the upper rotating base 131, the lower rotating base 132, and the vertical rod 12 are positioned and fixed via the screw.

[0039] In this embodiment, there are two types of connection joints. The first type is located at an edge of the frame 1, the connection rod 1311 is connected on a side of the upper rotating base 131 or the lower rotating base, 132, as shown in FIG. 7, a side of the connection joint 13 is connected to the cross rod 11 in this case. The second type is located at the middle of the frame 1, the connection rod 1311 is connected to both the upper rotating base 131 and the lower rotating base 131, as shown in FIG. 6, two sides of the connection joint are connected to the cross rod 11 in this case.

[0041] During assembling, the cross rod 11 penetrates into the transverse casing 22, and the transverse casing 22 is connected to both an upper part and a lower part of each shielding plate 21. That is, the shielding plate is expanded via the two transverse casings 22, and then the cross rod 11 and the vertical rod 12 are connected and fixed via the connection joint 13. Two adjacent cross rods 11 may rotate relative to each other via the upper rotating base 131 and the lower rotating base 132 of the connection joint 13. During transportation, components may be disassembled, especially the whole frame 1 may be in a shape of a rod after being completely disassembled. Therefore, small overall space is occupied.

[0042] The shielding plate 21 in this embodiment may be a plate or a fabric.

[0043] The screen in this embodiment may be folded by rotating at the connection joint 13. That is, the two adjacent cross rods 11 are stacked together, as shown in FIG. 12.

[0044] Certainly, in this embodiment, one piece of the screen may be used. In this case, the screen does not need to be folded when being stored. When two or more pieces of the screens are used together, the screens may be folded in the above manner.

[0045] Preferably, the vertical rod includes an upper vertical rod 121 and a lower vertical rod 122 from a middle of the vertical rod. The upper vertical rod 121 may be detachably connected to the lower vertical rod 122. Therefore, by dividing the vertical rod into two parts, occupied space of an over length can be reduced during transportation. As shown in FIG. 8, preferably, the upper vertical rod 121 is connected to the lower vertical rod 122 in a threaded manner. Specifically, an internally threaded chamber is processed on the upper vertical rod 121, an externally threaded insertion head is processed on the lower vertical rod 122. The upper vertical rod 121 and the lower vertical rod 122 can be detached by the threaded fit between the externally threaded insertion head and the internally threaded chamber.

In this case, the positioning convex edges 1321 are round as a whole, and correspondingly, the cross rod 11 is in a shape of a circular cylinder. As shown in FIG. 5, the cross-section of the connection rod 1311 may also be square. In this case, the positioning convex edges 1321 are square as a whole, and correspondingly, the cross rod 11 is in a shape of a square cylinder. The positioning convex edges 1321 may be continuous around the connection rod 1311 for a circle or intermittent around the connection rod 1311 for a circle.

[0058] Certainly, the cross-section of the connection rod 1311 may also be other shapes, such as plum-shaped, oval, or polygonal, as long as the shape of the cross rod 11 is adapted to the connection rod 1311.

[0059] In another embodiment, in a connection structure between the connection rod 1311 and the cross rod 11, the connection rod 1311 is connected to the cross rod 11 in a threaded manner. The connection rod 1311 and the cross rod 11 that are connected in a threaded manner may be assembled and disassembled by screwing the connection rod 1311 and the cross rod 11.
