Summary of the invention
It is simple that technical problem to be solved by this invention is to provide a kind of structure, good stability, anti-stealing manhole cover that can be antitheft.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of anti-stealing manhole cover, comprise manhole cover body and be positioned at the draw-in groove on the borehole wall, described manhole cover body is circular, its inside has the through hole running through manhole cover body diameter, in described through hole, there is symmetrically arranged fastening part, described fastening part is made up of spring one and kelly, described spring one is connected with described kelly, lift block is provided with between symmetrical spring one, described lift block top perforate coordinates with the lifting rod bottom on it, the circular hole that described lifting rod top is arranged through described manhole cover body center, spring two is provided with in described draw-in groove, one end of described spring two is fixedly connected with the bottom of described draw-in groove.
As a further improvement on the present invention, described spring one top is provided with resilient protection head.
As a further improvement on the present invention, there is the screw thread of screw thread and described lifting rod bottom to mating in the hole on described lift block.
As a further improvement on the present invention, described circular hole is provided with over cap.
As a further improvement on the present invention, described over cap is provided with circular arc pulling part.
Anti-stealing manhole cover of the present invention, structure is simple, and cost is low, excellent stability, has good anti-theft effect.
Accompanying drawing explanation
Fig. 1 is the perspective view of anti-stealing manhole cover of the present invention;
Fig. 2 is the internal construction schematic diagram of anti-stealing manhole cover of the present invention.
Detailed description of the invention
As depicted in figs. 1 and 2, the anti-stealing manhole cover of the specific embodiment of the invention, comprise manhole cover body 10 and be positioned at the draw-in groove 6 on the borehole wall 20, manhole cover body is circular, its inside has the through hole 8 running through manhole cover body diameter, in through hole 8, there is symmetrically arranged fastening part, fastening part is made up of spring 1 and kelly 4, spring 1 is connected with kelly 4, lift block 2 is provided with between symmetrical spring 1, the top perforate of lift block 2 coordinates with lifting rod 1 bottom on it, preferably, there is the screw thread of screw thread and lifting rod 1 bottom to mating in hole on lift block 2, the circular hole 9 that lifting rod 1 top is arranged through manhole cover body center, circular hole 9 is provided with over cap 7, rainwater or other foreign material are entered in available protecting circular hole, impact uses, over cap is provided with circular arc pulling part 71, be convenient for people to open over cap, spring 2 61 is provided with in draw-in groove 6, one end of spring 2 61 is fixedly connected with the bottom of draw-in groove 6, spring 1 top is provided with resilient protection head 5.
Operating principle of the present invention is: when installing well lid, lifting rod is utilized to be pressed into by lift block between two springs 1, spring 1 and kelly 4 are moved to both sides under the squeezing action of lift block, the draw-in groove 6 that kelly 4 gos deep on the borehole wall is inner, well lid is fixedly connected with the borehole wall, be less likely to occur to rock, thief is also not easy to steal; Need to open well lid when safeguarding, only need lifting rod 1 to insert lift block, lift block is mentioned, two springs 1 are drawn close to centre, the elastic force of the spring 2 61 simultaneously in draw-in groove 6 promotes kelly 4 and leaves draw-in groove 6, and well lid and the borehole wall depart from annexation, and people conveniently can remove well lid.
Anti-stealing manhole cover of the present invention, structure is simple, and cost is low, excellent stability, has good anti-theft effect.
Above embodiment is with reference to accompanying drawing, to a preferred embodiment of the present invention will be described in detail.Those skilled in the art by carrying out amendment on various forms or change to above-described embodiment, but when not deviating from essence of the present invention, drops within protection scope of the present invention.
