Triangular ladder capable of preventing crashing injury
The invention relates to the technical field of tools, in particular to an anti-crushing triangular ladder which comprises a step groove and a telescopic mechanism. The stepped grooves are formed in each foot of the triangular ladder, and the telescopic mechanisms are mounted in the stepped grooves. The telescopic mechanism comprises a rotating part, a connecting rope, an elastic supporting device, a leveling block and a handle. The rotating piece is rotationally connected to the inner side wall of the first groove, through holes are formed in the legs of the triangular ladder, one end of the connecting rope is fixedly connected with the rotating piece, and the other end of the connecting rope is fixedly connected with the leveling block. The first end of the elastic supporting device is fixedly connected with the upper wall of the second groove, and the second end of the elastic supporting device is fixedly connected with the upper end face of the leveling block. When the folded triangular ladder is placed on the ground, the four feet of the triangular ladder are in surface contact with the ground, so that the folded triangular ladder can be effectively prevented from toppling over, and the situation that people are injured due to toppling over of the triangular ladder can be effectively avoided.
本发明涉及工具技术领域，特别是涉及一种可以防止砸伤的三角梯，包括阶梯槽和伸缩机构；阶梯槽开设在三角梯的每个脚上，伸缩机构安装在每个阶梯槽内部；伸缩机构包括转动件、连接绳、弹性支撑装置、垫平块和手柄；转动件转动连接在第一槽的内侧壁上，三角梯的脚上开设有通孔，连接绳的一端与转动件固定连接，连接绳的另一端与垫平块固定连接；弹性支撑装置第一端与第二槽的上壁固定连接，弹性支撑装置第二端与垫平块的上端面固定连接。本发明实现收纳后的三角梯放置在地面上时，三角梯的四个脚与地面处于面接触的状态，可以有效的防止收纳后的三角梯倾倒，可以有效的避免因三角梯的倾倒砸伤人们的情况发生。
