[0100] See also Figures 10 to 16In this embodiment, an extension rod 500 is disposed in the groove 320 of the guardrail 300; one end of the extension rod 500 facing the free end 302 of the guardrail 300 is rotatably connected to the guardrail 300, so that the extension rod 500 can be rotated to one end beyond the free end 302 of the guardrail 300, thereby extending the length of the guardrail 300 in the extension direction, so as to be able to block higher objects.
[0101] When the height of the guardrail 300 does not need to be extended, the extension rod 500 is rotated to be accommodated in the groove 320 of the guardrail 300. When the length of the guardrail 300 needs to be extended, the extension rod 500 is rotated until one end exceeds the free end 302 of the guardrail 300.
[0102] A rotating hole 330 is formed at the free end 302 of the guardrail 300 , and a rotating shaft 510 is disposed on the extension rod 500 . The rotating shaft 510 passes through and is rotatably disposed in the rotating hole 330 .
[0103] In this embodiment, the rotating hole 330 extends in a straight line, and the extension direction of the rotating hole 330 is parallel to the extension direction of the guardrail 300; a locking hole 340 is provided at the end of the free end 302 of the guardrail 300, and a protruding locking protrusion 520 is formed on the outer periphery of the extension rod 500; when the extension rod 500 rotates to one end beyond the free end 302 of the guardrail 300, the extension rod 500 can slide along the extension direction of the guardrail 300, so that the locking protrusion 520 is engaged in the locking hole 340, thereby limiting the position of the extension rod 500 and maintaining the position of the extension rod 500 on the guardrail 300.
[0104] After the extension rod 500 rotates from the groove 320 to the preset position, the extension rod 500 exceeds the free end 302 of the guardrail 300, and then moves along the length direction of the guardrail 300, driving the rotating shaft 510 to move in the rotating hole 330, and driving the locking protrusion 520 to move in the locking hole 340, so that the locking protrusion 520 is engaged in the locking hole 340, limiting the rotation of the extension rod 500.
[0105] In one embodiment, the latching protrusion 520 is slidably disposed on the extension rod 500 , and when the extension rod 500 is rotated to be accommodated in the groove 320 , the latching protrusion 520 contracts inwardly into the extension rod 500 so that the extension rod 500 can be accommodated in the groove 320 .
[0106] In another embodiment, the latching protrusion 520 is detachably disposed on the extension rod 500 , so that when the extension rod 500 is rotated to be accommodated in the groove 320 , the latching protrusion 520 will not affect the accommodation of the extension rod 500 in the groove 320 .
[0107] In the present invention, a bearing surface 110 for bearing articles is formed on the upper surface of the tray 100, and the rotating end 301 of the guardrail 300 is rotatably connected to the tray 100 around a horizontal axis, so that the guardrail 300 can rotate in a vertical plane, driving the guardrail 300 to switch between an extended state and a stored state. When the guardrail 300 rotates upward to the extended state, the free end 302 of the guardrail 300 is higher than the bearing surface 110 of the tray 100, so as to block the side of the articles on the bearing surface 110, which can effectively prevent the articles from falling from the pallet, and effectively ensure the safety of the articles on the pallet.
[0108] When the guardrail 300 rotates to the expanded state, the locking member 400 can move and lock between the rotating end 301 of the guardrail 300 and the pallet 100 to limit the rotation of the guardrail 300 to maintain the expanded state of the guardrail 300, thereby maintaining the blocking of the items on the pallet 100.
