The screw is crossed to the lower surface of gag lever post, the side roof part of gag lever post two is compressed with well head bottom surface, and axle sleeve upper end protruding end both sides are respectively set
Put a supporting mechanism.
As preferred technical scheme, the connector includes an end cap and is arranged at the screw rod of end cap bottom, end cap
In the step surface for being arranged at axis hole upper end, screw rod is through the screw in the middle of axle sleeve to axle sleeve lower surface.
As preferred technical scheme, a spring, spring top and end cap are set with the screw rod of the end cap lower end
Lower surface is contacted, and lower spring end face is contacted with step surface.
As preferred technical scheme, the supporting mechanism includes a fixed cover and is inserted in flexible in fixed cover
There is compression spring, expansion link is inserted in fixed cover and contacted with internal compression spring in bar, fixed cover.
As preferred technical scheme, the well lid pours intracavitary joints cement.
As preferred technical scheme, a supporting pad, supporting pad and well head lower end are provided with the top of the gag lever post
Face is contacted.
The beneficial effects of the utility model are：The utility model is simple in construction, inspection well cover can be firmly fixed in
In well head, it is difficult to rock, is not easy to occur displacement easily, increases antitheft coefficient and security.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.

State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
As shown in figure 1, including the well lid 1 being installed in well head 7 and the locking device for being arranged at the lower end of well head 7, well lid 1
Centre sets one to pour chamber, and the centre for pouring chamber is provided with a raised metal axle sleeve 15, and metal axle sleeve 15 is passed through from top to bottom
Wear and be equipped with an axis hole 16, the upper surface of axis hole 16 is provided with a step surface, and axis hole is provided with a connection piece, connector
Through axis hole 16 to the lower surface of well lid 1, locking device includes a gag lever post 14, and the center top of gag lever post 14 sets an axle sleeve
11, it is provided through a screw in the middle of axle sleeve 11, connector is through the screw to the lower surface of gag lever post 14, the both sides of gag lever post 14
Top is compressed with the bottom surface of well head 7, and axle sleeve upper end protruding end both sides respectively set a supporting mechanism.
In the present embodiment, connector includes an end cap 3 and is arranged at the screw rod 12 of the bottom of end cap 3, and end cap 3 is arranged at axle
In the step surface of the upper end of hole 16, screw rod 12 is through the screw in the middle of axle sleeve 15 to the lower surface of axle sleeve 15, on the screw rod of end cap lower end
