Description
Technical field
Lid arrangement in the well head that the utility model relates to a kind of safe antitheft.
Background technology
Well lid in road is mainly used in the deep-well on defiladed route, according to the difference of each subterranean pipe line, some deep-wells are as waterway pipe, cable tubing or gas pipeline etc., deep-well be provided with the maintenance being beneficial to pipeline, but at some in particular cases, heavy rain or human factor cause well lid remove and cause personnel or object to fall into deep-well, or are impacted and jack-up by pressure in deep-well, and the appearance of these phenomenons all will bring huge potential safety hazard to the trip of people.Simultaneously when well lid is as raceway, often there is lawless person steals cable situation generation by removing well lid, bringing loss to national wealth.
Summary of the invention
Lid arrangement in the well head that the purpose of this utility model is to provide a kind of safe antitheft, this device not only compact conformation, and inner cap can be locked on well lid seat ring, prevent inner cap to be unlocked.
The technical solution of the utility model is: lid arrangement in a kind of well head of safe antitheft, comprise the well lid seat ring for placing well lid, be provided with in described well lid seat ring and prevent usurping inner cap, the inside wall of well lid seat ring is circumferentially laid with at least two grooves, described inner cap perimembranous correspondence to be provided with fit depressions with the projection preventing inner cap from washing from well lid seat ring, covers also to be provided with and match to be locked in the latching device in well lid seat ring with well lid seat ring in described.
Further, described latching device comprises the rotary locking cylinder passed in the middle part of inner cap from top to bottom, the rotating shaft of rotary locking cylinder is connected with the rotating disk be positioned at below inner cap, described rotating disk perimembranous interval is hinged with at least two connecting rods, the described connecting rod other end is hinged with the horizontal type telescopic slide bar passing inner cap lower flange, and described well lid seat ring inside wall bottom correspondence is provided with the slotted eye with horizontal type telescopic slide bar matching ends.
Further, described rotating disk perimembranous interval is hinged with three horizontal link levers.
Further, the inside wall of described well lid seat ring is circumferentially laid with four grooves, described inner cap perimembranous correspondence is provided with four and turns shape projection.
Further, described groove is L-type, and described L-type bottom portion of groove has the sagging recess allowing projection sink.
Further, described inner cap upper surface has and holds handle for rotary lifting inner cap.
Further, described inner cap bottom is also provided with reinforcing rib.
Compared with prior art, the utility model has the following advantages: this device not only compact conformation, and inner cap can be locked on well lid seat ring by latching device, prevents interior cover lawless person from opening, can available protecting national wealth; Utilize L-type groove to coordinate with projection, in the well lid seat ring that inner cap is fixed on below well lid, not only can prevent inner cap from falling, can also prevent because deep-well internal gas pressure is excessive, interior cover washes from well lid seat ring, has market prospects widely simultaneously.

Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below, but the utility model is not limited to this.
Referring to figs. 1 to Fig. 4, lid arrangement in a kind of well head of safe antitheft, comprise the well lid seat ring 1 for placing well lid, be provided with in described well lid seat ring and prevent usurping inner cap 2, on the inside wall of well lid seat ring, circumferentially interval is laid with four grooves 11, described inner cap perimembranous correspondence is provided with and turns shape projection 21 with fit depressions with what prevent inner cap from washing from well lid seat ring, covers also to be provided with to match being locked in well lid seat ring with well lid seat ring and prevent the latching device that interior cover lawless person opens in described.
In the present embodiment, described latching device comprises the rotary locking cylinder 31 passed in the middle part of inner cap from top to bottom, the rotating shaft of rotary locking cylinder is connected with the rotating disk 32 be positioned at below inner cap, described rotating disk perimembranous interval is hinged with three connecting rods 33, the described connecting rod other end is hinged with the horizontal type telescopic slide bar 34 passing inner cap lower flange 22, and described well lid seat ring inside wall bottom correspondence is provided with the slotted eye 12 with horizontal type telescopic slide bar matching ends.
In the present embodiment, described groove is L-type, and described L-type bottom portion of groove has the sagging recess 111 allowing projection sink.
In the present embodiment, described inner cap upper surface has and holds handle 23 for rotary lifting inner cap with what mentioned by inner cap.
In the present embodiment, described inner cap bottom is also provided with reinforcing rib 24.
The mode of occupation of this device: by corresponding with the groove of well lid seat ring for the interior projection covered, inner cap rotates inner cap after sinking, be sunken under making projection in sagging recess, manhole cover base circle is washed from greatly because pressing through in pipeline to prevent inner cap, the private key of opening lock master is inserted lock core, after rotating key, the rotating shaft of lock core drives dial rotation, thus drive link drives horizontal type telescopic sliding bar, make in the slotted eye of working tips fill-in well cage circle inside wall bottom of horizontal type telescopic slide bar, thus prevent interior cover lawless people from opening.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
