Anti-falling well lid for municipal engineering
The invention discloses an anti-falling well lid for municipal engineering. The anti-falling well lid comprises a vertical shaft, wherein a well ring and a well lid body are arranged above the vertical shaft, a mounting pipe is vertically arranged on the lower end surface of the well lid body, a locking pipe communicating with the interior of the mounting pipe is horizontally arranged at the lowerend of the mounting pipe, and locking rods are slidably connected to the ends of the locking pipe; a locking groove allowing the locking rods to be inserted and fixed is formed in the inner wall of the vertical shaft, the ends of the locking pipes are bent inwards to form flangings, limiting rings for abutting against the flangings are arranged on the end surface close to each other, of the two locking rods, and compression springs located between flangings and the limiting rings sleeve the locking rods; and two ends of each compression spring are fixedly connected with the limiting rings andthe flangings respectively, and a reset mechanism used for controlling the two locking rods to get close to each other is arranged in the locking pipe. Compared with the prior art, the anti-falling well lid has the following advantages and effects that through cooperation of the locking rods and the locking groove, after the well lid is mounted, the position of the well lid is completely limited,the well lid can bear acting force in the vertical direction, and has the advantage of being prevented from falling off.
本发明公开了一种市政工程防脱井盖，包括竖井，竖井的上方设置有井圈和井盖，井盖的下端面竖直设置有安装管，安装管下端水平设置有与其内部相连通的锁定管，锁定管的端部均滑动连接有锁定杆，竖井的内壁开设有供锁定杆插接固定的锁定槽，锁定管的端部向内弯折并形成翻边，两个锁定杆相互靠近的端面均设置有用于抵触翻边的限位环，锁定杆上套设有位于翻边与限位环之间的压缩弹簧，压缩弹簧的两端分别与限位环和翻边固定连接，锁定管内设置有用于控制两个锁定杆相互靠近的复位机构。本发明具有以下优点和效果：通过利用锁定杆和锁定槽的配合，当井盖安装完成后，实现井盖位置的完全限定，使得井盖既能承受竖直方向的作用力，从而具有防脱的优点。
