Description
Technical field
The utility model relates to a kind of well lid, is specifically related to a kind of manhole lid device that is easy to open.
Background technology
On road, cross walk or pedestrian street, see many well lids through regular meeting; in order to bear certain pressure; the material of well lid is generally all selected cast iron for use; be embedded on the road or after on the cross walk; because it is more thick and heavy; often be not easy to open; in order to be easy to raise well lid; great majority all are provided with aperture on well lid; need carry crowbar or hook when opening stretches in the aperture and opens it; for some urgent accidents of processing, under the situation of not carrying external tool, well lid is difficult to be opened.
Summary of the invention
The utility model provides a kind of reasonable in design in order to solve the deficiencies in the prior art, can raise the manhole lid device of well lid under the situation that does not need the instrument that carries quickly and easily.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of manhole lid device that is easy to open, comprise lid, described lid is installed draw rod device by aperture, described draw rod device comprises the connecting rod that can stretch up and down, described connecting rod one end stretches in the aperture, and be provided with attachment cap in its end, and the described connecting rod other end stretches out aperture, and its other end end is provided with block.
Described draw rod device is arranged on the position near the lid edge.
Described little bore edges is provided with groove, and described block is embedded on the groove, and described block and top surface are in a plane.
Described block is circular, square or rhombus.
Described attachment cap is a nut, is installed in an end of connecting rod by screw.
Described attachment cap and connecting rod are one, and the diameter of described attachment cap is greater than the diameter of described aperture.
Described connecting rod is connected with attachment cap and/or block by welding.
Compared with prior art, adopt structure of the present utility model, lid is installed draw rod device by aperture, when needs are opened well lid, need be by any instrument, only need the pull-up block, attachment cap by connecting rod and end thereof, just can easily easily heavy well lid be started, draw rod device is arranged on the marginal position of well lid, and comparatively the labour-saving starts well lid, and block is in a plane with top surface, can not influence the quality on road surface because of the projection or the depression of block, make vehicle be easy to by.The utility model is reasonable in design, simple in structure, easy to use, for the maintenance work below the well lid brings great convenience.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 be among Fig. 1 A-A to a kind of structure sectional view;
Fig. 3 be among Fig. 1 A-A to another kind of structure sectional view.
Among the figure: 1 lid, 2 connecting rods, 3 attachment caps, 4 blocks, 5 apertures, 6 grooves,
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, a kind of manhole lid device that is easy to open comprises lid 1, and draw rod device is installed by aperture 5 in lid 1 edge, described draw rod device comprises the connecting rod 2 that can stretch up and down, connecting rod 2 one ends stretch in the aperture 5, and in its end fixedly connected cap 3, connecting rod 2 other ends stretch out aperture 5, its other end end is provided with block 4, aperture 5 edges are provided with groove 6, and block 4 is embedded on the groove, and block 4 is in a plane with lid 1 surface.
Referring to Fig. 3, as another kind of embodiment, attachment cap 3 is an one with connecting rod 2, and the bending that connecting rod 2 one ends can be made progress can not be removed connecting rod 2 these ends by aperture 5 and is advisable.Block 4 can be designed to circle, square or rhombus according to the design needs.
At the normal mounting state, connecting rod is suspended on the edge of well lid by block, during use, the pull-up block is opened well lid by connecting rod, and is time saving and energy saving, for avoiding draw rod device stolen, the attachment cap at connecting rod two ends and block can be connected on the connecting rod by the mode of welding, like this draw rod device be not easy removed, only as opening the well lid use.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
