Folding guardrail capable of reducing transportation volume
The invention provides a folding guardrail capable of reducing the transportation volume. An upper cross rod and a lower cross rod which are parallel to each other and transversely arranged are connected between two stand columns, a plurality of vertical rods which are parallel to each other and longitudinally arranged are connected between the upper cross rod and the lower cross rod, the lower ends of the vertical rods are connected with the lower cross rod, and the upper ends of the vertical rods penetrate through the upper cross rod and extend to the upper portion of the upper cross rod. The folding guardrail further comprises a vertical positioning clamping base and a horizontal positioning clamping base which are fixed to the lower cross rod, each vertical rod comprises a fixed cylinder and a movable cylinder which are connected in a telescopic mode, a through hole is formed in the upper cross rod, the movable cylinders can penetrate through the through hole and partially extend to the upper portion of the upper cross rod, and the fixed cylinders are rotationally connected with the lower cross rod. When the movable cylinders retract into the fixed cylinders, the fixed cylinders can rotate around the rotating joints of the fixed cylinders and the lower cross rod; when the fixed cylinders drive the movable cylinders to rotate to the vertical position, the fixed cylinders are clamped in clamping openings of the vertical positioning clamping base, and the movable cylinders can upwards penetrate through the through hole; and when the fixed cylinders drive the movable cylinders to rotate to the horizontal position, the fixed cylinders are clamped in clamping openings of the horizontal positioning clamping base.
一种可减少运输体积的折叠护栏，两个立柱之间连接有相互平行并横向设置的上横杆和下横杆，上横杆和下横杆之间连接有若干相互平行并纵向设置的竖杆，竖杆的下端与下横杆连接，竖杆的上端贯穿上横杆并伸至上横杆的上方，还包括固定在下横杆上的竖直定位卡座和水平定位卡座，竖杆包括伸缩连接的固定筒和活动筒，上横杆上设有通孔，活动筒可穿设通孔并部分伸至上横杆的上方，固定筒与下横杆转动连接，在活动筒缩进固定筒时，固定筒可绕其与下横杆的转动连接处转动，在固定筒带着活动筒旋转至竖直位置时，固定筒卡在竖直定位卡座的卡口内，活动筒可向上穿设通孔，在固定筒带着活动筒旋转至水平位置时，固定筒卡在水平定位卡座的卡口内。
