Ladder with adjustable inclination angle
The invention relates to a ladder with an adjustable inclination angle. The ladder comprises two vertical stand columns and a plurality of transverse connecting rods used for connecting the two vertical stand columns; adjusting rods are arranged on the same sides of the multiple transverse connecting rods at intervals, the outer ends of the adjusting rods are provided with size-adjustable straps,and the transverse connecting rods are correspondingly provided with front-back through holes allowing the adjusting rods to penetrate and vertical positioning bolts corresponding to screw holes in the adjusting rods; and the lower ends of the two vertical stand columns are cylindrical column bodies, and telescopic positioning structures are arranged in inner cavities of the cylindrical column bodies. By means of the ladder, the inclination angle can be adjusted and fixed, and the lower ends of the ladder are provided with positioning structures, so that the safety of field operation can be greatly improved.
一种可调节倾斜角度的梯子，包括两根竖向立柱以及用于连接两根竖向立柱的若干根横向连杆；若干个横向连杆的同一侧间隔布置着调节杆，调节杆的外端设置着大小可调的箍带，横向连杆上对应设置着用于容纳调节杆穿过的前后向通孔和与调节杆上的螺孔相对应的竖向定位螺栓；两根竖向立柱的下端为圆柱状柱体，圆柱状柱体的内部腔体中设置有可伸缩的定位结构。该梯子不仅可调节并固定倾斜角度，其下端下端还具有定位结构，可大大提高野外作业的安全性。
