The invention discloses an inspection well lid with an anti-theft function for municipal infrastructure. The lid comprises a lid body, wherein a groove and a threaded groove are formed in the upper end of the lid body, two telescopic cavities are formed in the lower end of the lid body, a transition cavity communicating with the threaded groove and the telescopic cavities is formed in the lid body, and a strong spring is welded to the lower end of a lifting plate. According to the lid, the groove, the threaded groove, the transition cavity and the telescopic cavities which are in communicationwith one another are sequentially formed in the lid body, a telescopic rod which is connected with a locking column and a driving piston are arranged in the transition cavity, a driven piston which is elastically limited and supported by a return spring, a pull rod and a locking bolt are arranged in each telescopic cavity, the lifting plate is movably arranged in the groove, and the locking column capable of being fixedly connected is connected to the lower end of the lifting plate through the strong spring so that the driving piston can be driven to move up and down in the transition cavityonly by rotating the locking column while pressing the lifting plate, and thus the locking bolt can be prevented from being directly pulled to contract through the lifting plate, and the inspection well lid is prevented from being directly opened.
本发明公开了一种具有防盗作用的市政基建用窨井盖，包括盖体，盖体上端分别开设有凹槽与螺纹槽，且盖体下端开设有两个伸缩腔，盖体内开设有连通螺纹槽与伸缩腔的过渡腔，且升降板下端焊接有强力弹簧。本发明在盖体中依次开设相连通的凹槽、螺纹槽、过渡腔与伸缩腔，通过在过渡腔中设置与锁紧柱相连接的伸缩杆与主动活塞，在伸缩腔中设置由复位弹簧弹性限位支撑的从动活塞、拉杆与锁紧栓；通过在凹槽中活动设置升降板，并在升降板下端利用强力弹簧连接可固定连接的锁紧柱，使得只有在按压升降板的同时旋转锁紧柱才能带动主动活塞在过渡腔中实现上下移动，可避免通过升降板直接牵引锁紧栓收缩，从而防止窨井盖被直接开启。
