[0023] Each of the side panel units 10 includes two end connection side panels 11, a plurality of second connection side panels 12 connected between the end connection side panels 11, and a plurality of third connection side panels 13. One third connection side panel 13 is disposed between any two adjacent second connection side panels 12, that is, the second connection side panels 12 and the third connection side panels 13 are alternately disposed.

[0024] The end connection side plate 11 includes an end connection side plate body 111, a rectangular groove 112 arranged on one side of the end connection side plate body 111, and a first connection pivot hole 113 arranged on one side of the rectangular groove 112. The two end connection side plates 11 are respectively arranged at the two ends of the drag chain as the head and tail ends of the drag chain. The rectangular groove 112 is used to facilitate the dragging and picking up of the drag chain. The end connection pivot hole 113 is a circular groove opened on the end connection side plate body 111, a columnar connection protrusion 1131 is arranged in the middle of the circular groove, and two first arc-shaped limiters 1132 are symmetrically arranged on both sides of the columnar connection protrusion. When the end connecting side plate 11 and the second connecting side plate 12 are connected to each other, the first arc-shaped limiter 1132 is used to limit the rotation range between the end connecting side plate 11 and the second connecting side plate 12, and the arc size of the first arc-shaped limiter 1132 can be set according to the rotation range requirements of the drag chain.

[0025] The second connecting side plate 12 includes a second connecting side plate body 121 and two second connecting pivot holes 122 arranged in parallel on one side of the second connecting side plate body 121. The two ends of the second connecting side plate body 121 are arranged in an arc shape to facilitate the rotation of the second connecting side plate 12. The second connecting pivot hole 122 is used to connect with the third connecting side plate 13, and each of the second connecting pivot holes 122 includes a second pivot hole body 1221, a connecting sleeve 1222 arranged in the middle of the second pivot hole body 1221, and two limit cards 1223 symmetrically arranged on both sides of the connecting sleeve 1222. The second connecting pivot hole 122 is used to connect the end connecting side plate 11 and the third connecting side plate 13, so the second connecting side plate will be described in detail as a whole in combination with the third connecting side plate 13 below.

[0026] The third connecting side plate 13 includes a third connecting side plate body 131 and two third connecting pivot holes 132 arranged in parallel on the third connecting side plate body 131.

When the end connection side plate 11 and the second connection side plate 12, and the third connection side plate 13 are connected to each other, the connection sleeve 1222 is movably sleeved on the columnar protrusion 1131 between the end connection side plate 11 and the second connection side plate 12, and the limit card 1223 is clamped in the gap between the two first arc-shaped limit pieces 1132. Between the second connecting side plate 12 and the third connecting side plate 13, the connecting sleeve 1222 is movably mounted on the connecting column 1322, and the limiting card 1223 is clamped in the gap between the second arc-shaped limiting pieces 1323. During the rotation of the second connecting side plate 12 and the third connecting side plate 13, the limiting card 1223 can abut against the edge of the second arc-shaped limiting piece 1323 to limit the rotation range between the second connecting side plate 12 and the third connecting side plate 13.

[0028] Therefore, the end connection side plate 11, the second connection side plate 12, and the third connection side plate 13 are connected through the end connection pivot hole 113, the second connection pivot hole 122, and the third connection pivot hole 132 to form a complete side plate unit 10. And because the end connection side plate 11, the second connection side plate 12, and the third connection side plate 13 are connected through the pivot hole, they are easy to install and can be disassembled at will, and the length of the drag chain can be flexibly adjusted according to the actual length required for use.
