Abstract
The utility model discloses a well hoop theft-proof bolt. The theft-proof bolt comprises a hoop and a bolt, wherein the bolt comprises an inner thread hollow shell and an outer thread inner hexagonal bolt. The bolt hole of the hoop is provided with a stair, so the inner diameter of the bolt hole is slightly less than the diameter of the outer end. Through the utility model, the stair is arranged in the hoop bolt hole, the fixing bolt is divided into mutually matched inner thread hollow shell and outer thread inner hexagonal bolt and the bolt is in a same plane of the hoop or is slightly lower than the hoop after the hoop is fixed, therefore preventing the bolt from being detached with a wrench by the lawbreaker and achieving the theft-proof effect of the well hoop.
Description
Technical field
The utility model relates to the fixing device of oilfield oil well well head clip, especially a kind of open-air well station anti-theft device of clip.
Background technique
Open-air well station, oil field oil/water well generally is that expose at the two ends that are fixed on the clip hole with the clip bolt, existing clip bolt is very easily unclamped with spanner by the lawless person and discharges, thereby steal clip, cause any property loss to the oil field, more seriously cause the oil well stopping production or cause the ground pollution in wide area, thereby bring bigger economic loss to country.
The model utility content
The technical problems to be solved in the utility model is for overcoming above-mentioned deficiency, and a kind of well head clip anti-theft bolt of simple in structure, easy to use, good anti-theft effect is provided.
The utility model is taked following technical measures: a kind of well head clip anti-theft bolt, comprise clip, bolt, described bolt is made of six rib bodies of bolt cooperation in internal thread hollow casing and the outer silk, be provided with step in the bolt hole of described clip, make the bolt hole inside diameter be slightly smaller than the outboard end diameter.
The beneficial effects of the utility model are that design in original clip bolt hole is had step, fixed-use bolt is divided into six rib bodies of bolt cooperation in internal thread hollow casing and the outer silk, make behind the fixing hoop body of bolt become a plane with clip or a little less than the clip plane, thereby the phenomenon of having avoided the lawless person to dismantle with spanner reaches the antitheft effect of well head clip.Compared with prior art, advantage such as simple, easy to use, good anti-theft effect of concrete structure.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, a kind of well head clip anti-theft bolt comprises clip 1, bolt, described bolt is made of the six rib bodies of bolt, 3 cooperations in internal thread hollow casing 2 and the outer silk, is provided with step 5 in the bolt hole 4 of described clip 1, makes bolt hole 4 inside diameters be slightly smaller than the outboard end diameter.
The concrete using process of the utility model is as follows: internal thread hollow casing 2 is penetrated from paired clip 1 bolt hole 4 belows, the six rib bodies of bolt 3 in the silk outside install clip bolt hole 4 tops, with special spanner will outer silk in six rib bodies of bolt 3 cooperate with internal thread hollow casing 2 and install, body of bolt two ends after the combination are stuck on the step 5 in clip 1 bolt hole 4, make 1 one-tenth one plane of the body of bolt and clip or a little less than clip 1 plane, thereby the phenomenon of having avoided the lawless person to dismantle with spanner reaches the antitheft effect of well head clip.
