Safety ladder for power distribution cabinet
The invention discloses a safety ladder for a power distribution cabinet. The safety ladder comprises a ladder body and a limiting device arranged close to the end part of the ladder body, wherein the limiting device comprises a fixed table, a fixed column, a limiting table, a first bolt and a second bolt; the fixed table is correspondingly fixed on a first column body and a second column body; a first through hole is formed in the middle of the fixed table and a first thread hole is formed in the side part of the fixed table; a limiting sheet is fixedly arranged at the first end part of the fixed column and a second thread hole is formed in the second end part of the fixed column; a plurality of first grooves, which are annularly distributed, are formed in the side part, corresponding to the first thread hole, of the fixed column respectively; the first bolt is connected with the first grooves through the first thread hole; the width of the limiting sheet is greater than the diameter of the first through hole; the diameter of the fixed column is smaller than or equal to the diameter of the first through hole; a U-shaped groove is formed in the top of the limiting table; two U-shaped lug bosses are formed at two sides of the U-shaped groove respectively; and second through holes are formed in the U-shaped lug bosses. The safety ladder is simple in structure and good in anti-inclining effect, and different angles and scenes can be flexibly switched.
本发明公开了一种用于配电柜的安全梯，包括梯体以及设置在靠近梯体端部的限位装置；限位装置包括固定台、固定柱、限位台、第一螺栓和第二螺栓；固定台对应固定在第一柱体和第二柱体上，固定台的中部设置有第一通孔，侧部设置有第一螺纹孔；固定柱的第一端部固定设置有限位片，固定柱的第二端部设置有第二螺纹孔，在固定柱对应第一螺纹孔的侧部分别设置多个圆环形分布的第一凹槽，第一螺栓通过第一螺纹孔与第一凹槽连接；限位片的宽度大于第一通孔的直径，固定柱的直径小于或等于第一通孔的直径；限位台的顶部设置有U型槽，在U型槽的两侧分别形成有两个U型凸台，U型凸台设置有第二通孔。结构简单，防倾效果好，灵活切换不同角度以及场景。
