Ladder main body, ladder joint and ladder
The invention relates to a ladder main body, a ladder joint and a ladder. The ladder joint comprises two ladder main bodies and a ladder joint for connecting the adjacent ladder main bodies, the ladder main body comprises a longitudinal support body; the longitudinal support body is provided with a slot; the slot is positioned at the end part of the longitudinal support body, which is used for being butted with a ladder joint; the ladder joint comprises two insertion parts used for being inserted into the insertion grooves; the insertion part is provided with a free end and a fixed end opposite to the free end; the insertion part is provided with a first side surface opposite to the bending direction of the ladder joint; the first side surface of the insertion part comprises a first section and a second section, and the first section is concavely arranged; the first section extends from the fixed end of the first side surface of the insertion part to the free end; the first section and the second section are sequentially arranged in the direction from the fixed end to the free end of the insertion part. According to the ladder joint, the phenomenon of stress concentration of the ladder joint and/or the ladder main body at the position is avoided, so that the ladder joint and/or the ladder main body are/is prevented from being damaged or damaged.
本发明涉及一种梯具主体、梯具关节及梯具。一种梯具关节，包括两个梯具主体以及用以连接相邻梯具主体的梯具关节；梯具主体包括纵向支撑体；纵向支撑体具有插槽；插槽位于纵向支撑体的用以与梯具关节对接的端部；梯具关节包括两个用以插入插槽的插入部；插入部具有自由端和与自由端相背的固定端；插入部具有与梯具关节弯折方向相背的第一侧面；插入部的第一侧面包括第一段和第二段，第一段凹陷设置；第一段由插入部的第一侧面的固定端开始向自由端的方向延伸；由插入部的固定端指向自由端的方向，第一段与第二段依次设置。上述梯具关节，避免梯具关节和/或梯具主体在该位置发生应力集中的现象，进而避免梯具关节和/或梯具主体损伤或者损坏。
