Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of well lid with safety lock, including pedestal 1
With manhole cover body 3, manhole cover body 3 is placed in the platform slot that 1 inner ring of pedestal opens up, and the inner sidewall of pedestal 1 is opened up there are two triangle
Slot 2, the position that 3 outer surface of manhole cover body corresponds to triangular groove 2 offer channel, the placement opened up inside channel and manhole cover body 3
Slot connection, the lower surface of placing groove inner wall are connected with bearing 4, and shaft 5, the top of shaft 5 and threaded post 6 are arranged in bearing 4
Bottom end be fixedly connected, the outer surface thread of threaded post 6 is connected with thread barrel 7, and the outer surface of thread barrel 7 passes through two springs 9
It being fixedly connected with the one side of corner block 10, corner block 10 is consistent with the size of triangular groove 2, and corner block 10 is located in channel,
The top of threaded post 6 offers keyhole 12, and the position that 3 upper surface of manhole cover body corresponds to placing groove opens up band internal thread
Annular groove, the connection of annular groove internal screw thread have externally threaded protective cover 13.
In the present embodiment, when needing to carry out installment work to manhole cover body 3, manhole cover body 3 is placed directly in pedestal 1
In interior platform slot, when manhole cover body 3 is bonded with the inner sidewall of platform slot, 10 automatic clamping of corner block under the elastic force effect of spring 9
