Anti-falling cable well mouth
An anti-falling type cable well mouth comprises a well body, the well body is divided into two sections, namely an upper-section well mouth and a lower-section well mouth, and the diameter of the upper-section well mouth is larger than that of the lower-section well mouth; the fixed ring is fixed in the upper-section well mouth, and a limiting groove and a gear ring are arranged on the inner ring side of the fixed ring; a deflector rod is arranged on the inner ring side of the limiting ring, a plurality of supporting feet are fixed to the outer ring side of the limiting ring in a divergent mode, the supporting feet are inserted into the limiting grooves, a plurality of supporting columns are arranged on the lower end face of the limiting ring, all the supporting columns are arranged on the lower portion of the limiting ring in an annular array mode, and each supporting column is correspondingly provided with a blocking piece which can rotate around the corresponding supporting column; each separation blade is of a semicircular structure, an inner concave arc and an outer convex arc are arranged on the edge of each separation blade, the inner concave arc and the outer convex arc are equal in radius, each outer convex arc is an arc edge with the hinge point as the circle center, each arc edge is divided into two sections, one section is provided with outer convex teeth which are meshed with the gear ring, and the other section is inserted into the inner concave arc on the adjacent separation blade in a sliding mode.
一种防坠落式电缆井井口，包括：井体，井体分为两段，分别为上段井口、下段井口，上段井口直径大于下段井口；固定环圈，固定环圈固定在上段井口中，固定环圈内环侧设有限位槽与齿环；限位圈，限位圈内圈侧设有拨杆，外圈侧发散式固定有多根撑脚，撑脚插入至限位槽中，限位圈下端面设有若干支撑柱，所有的支撑柱呈环形阵列排布在限位圈下部，每个支撑柱上对应安装一个挡片，挡片可绕支撑柱自转；挡片为半圆形结构，挡片的边缘处设有内凹弧与外凸弧，内凹弧与外凸弧半径相等，外凸弧为以铰接点为圆心的圆弧边，该圆弧边分为两段，一段设有外凸齿牙，外凸齿牙啮合在齿环上，另一段滑动插入至相邻的挡片上的内凹弧中。
