The carrier comprises a first support, a second support and a third support, the first support, the second support and the third support extend in the vertical direction in the unfolded state, the first support and the second support are rotationally connected, and a first limiting structure is arranged between the first support and the second support; the first support and the third support are rotationally connected, a second limiting structure is arranged between the first support and the third support, and a locking mechanism used for locking the second support and the third support is further arranged between the second support and the third support. When the carrier is in the unfolded state, the first support, the second support and the third support are mutually unfolded, the first limiting structure limits the second support to rotate in the first direction relative to the first support, the second limiting structure limits the third support to rotate in the second direction relative to the first support, and the first direction is opposite to the second direction. The second support and the third support are locked through the locking mechanism, so that the carrier is locked in the unfolded state.
本发明涉及一种载具,包括在展开状态下各自沿上下方向延伸的第一支架、第二支架及第三支架,所述第一支架与所述第二支架转动地连接且两者之间设置有第一限位结构;所述第一支架与所述第三支架转动地连接且两者之间设置有第二限位结构,所述第二支架与所述第三支架之间还设有用于将两者相互锁定的锁定机构。该载具在展开状态下,第一支架、第二支架及第三支架彼此相互展开,第一限位结构限制第二支架相对第一支架朝向第一方向转动,第二限位结构限制第三支架相对第一支架朝向第二方向转动,上述第一方向与第二方向相反,第二支架与第三支架通过锁定机构锁定,如此,便使得载具被锁定于展开状态下。
