Embodiment 1

[0025] refer to Figure 1-3 , a municipal anti-theft manhole cover, comprising a wellhead seat structure 1, a manhole cover structure and a driver structure 3;

[0026] The wellhead seat structure 1 includes a seat body 11, a circular manhole cover step 12 is arranged inside the seat body 11, and a plurality of locking grooves 13 are uniformly opened on the inner peripheral surface of the manhole cover step 12;

[0027] The driver structure 3 includes a transmission groove 31 and a transmission rod 32 that cooperate with each other. The upper end of the transmission rod 32 is fixedly connected with a vertical rod 33 , and the upper end of the vertical rod 33 is fixedly connected with a rotating rod 34 . It should be noted that the transmission slot 31 and the transmission rod 32 have a special structure corresponding to the structure principle of the lock and key in the prior art, which is an irregular structure.

[0028] The inner surface of lock groove 13 is coated with ant...

Embodiment 2

[0037] refer to Figure 4-6The difference between this embodiment and Embodiment 1 is that the well cover structure includes a second cover body 41, and the inner middle part of the second cover body 41 is provided with a second transmission cavity 42, and the outer peripheral surface of the second cover body 41 is formed by the first The second transmission chamber 42 is evenly provided with a plurality of second receiving grooves 43 in the circumferential direction of the circle, and the number of the second receiving grooves 43 is equal to that of the locking grooves 13, and the upper and lower inner walls of the second transmission chamber 42 are rotatably connected with a second helical rod 44 , the upper end of the second screw rod 44 is set through the second transmission cavity 42, the lock groove 13 is opened on the upper end of the second screw rod 44, and the upper and lower inner walls of the second transmission cavity 42 are symmetrically fixedly connected with the...

Abstract

The invention discloses a municipal anti-theft well lid. The municipal anti-theft well lid comprises a wellhead seat structure, a well lid structure and a driving piece structure, wherein the wellheadseat structure comprises a seat body, a circular well lid step is arranged inside the seat body, and a plurality of locking grooves are evenly formed in the inner circumferential surface of the welllid step; and the driving piece structure comprises a transmission groove and a transmission rod which are matched with each other, a vertical rod is fixedly connected to the upper end of the transmission rod, and a rotating rod is fixedly connected to the upper end of the vertical rod. The municipal anti-theft well lid has the advantages that in a normal use state, first locking plates are correspondingly abutted against the locking grooves, the transmission groove uses a special structure, a thief cannot easily drive a rotating shaft to rotate through the transmission groove, and the anti-theft performance is good.

Description

technical field [0001] The invention relates to the technical field of manhole covers, in particular to a municipal anti-theft manhole cover. Background technique [0002] Manhole covers are mainly used to cover the drains on the road to prevent people or objects from falling. And the current manhole covers are generally made of ferrous metal-like materials to provide sufficient supporting strength. And the anti-theft effect of the existing manhole cover is poor, and the situation of disappearing often occurs, and there is a certain security risk. [0003] In order to solve the above problems, we propose a municipal anti-theft manhole cover. Contents of the invention [0004] The purpose of the present invention is to solve the problems in the background technology, and propose a municipal anti-theft manhole cover. [0005] In order to achieve the above object, the present invention adopts the following technical solutions: a municipal anti-theft manhole cover, includin...
