The invention belongs to the technical field of ladders and particularly discloses a straight ladder with a good anti-sliding property. The straight ladder comprises two parallel straight ladder rods and a plurality of ladder sections arranged between the two straight ladder rods in parallel; an elastic anti-sliding block is arranged at the bottom end of each straight ladder rod; the supporting face of each elastic anti-sliding block is arc-shaped; and a saw-tooth structure is arranged on the arc-shaped supporting face. The elastic anti-sliding blocks are sleeved at the bottom ends of the straight ladder rods, and then fixes the bottom ends of the straight ladder rods through screw rods. The straight ladder provided by the invention is provided with the elastic anti-sliding blocks at the bottom ends of the straight ladder rods, so that the frication force of the ladder and a supporting face under the bearing effect can be increased. Therefore, the anti-sliding property of the ladder is better.
Description
technical field [0001] The invention relates to a ladder, in particular to a straight ladder with good anti-skid performance. Background technique [0002] At present, the straight ladders used in the construction industry are generally composed of two parallel linear ladder rods and a number of ladder sections arranged between the two linear ladder rods in parallel. In order to prevent the ladder from slipping during use, it is usually The bottom of the ladder bar is provided with anti-slip parts, but the anti-slip performance of the current anti-slip parts is poor, especially when the supporting ground is relatively smooth, it will cause slipping, which is easy to cause safety accidents and has potential safety hazards. Contents of the invention [0003] The object of the present invention is to provide a straight ladder with good anti-skid performance, which aims to solve the poor anti-slip performance of the current straight ladder in the construction industry, especia...
