Anti-stealing manhole cover with fixation and anti-theft function

Abstract

The invention relates to an anti-theft well cover with the fixing function and anti-theft function. The upper end edge of a well curb is further provided with two notches; a structure in which the well cover contained and matched by notches at the upper end edge of the well curb is movably matched and connected with the well curb is formed by the notches; the other symmetrical end of the bottom surface of the well cover also contains a special tool; an orientating hole, a bolt bracket, a rivet shaft, a torsion spring, a bolt lever and a locking core bracket which is tightly fixed and integrated at the edge of the well curb are matched and connected in a cupping way; the special tool is inserted to support the bolt lever so as to lead a horizontal hook to separate the lower end of the locking core bracket, so the well cover can be opened; the opened well cover can not be stolen and warn the vehicles and pedestrians to notice safety; and the well cover is put back to the well curb, the special tool is taken out, and the bolt lever automatically hooks the lower end of the locking core bracket under the elasticity of the torsion spring to tightly lock the two symmetrical ends of the well cover on the well curb. The invention has simple and novel structure and convenient opening and closing, is not effected by soil and rainwater, and can not be pressed to be turned over, thus achieving the purpose of leading the well cover to have the fixing function and anti-theft function.
