Description
Technical field:
The utility model relates to the used anti-theft device of wellhead polish rod side, oil recovery field, oil field card, especially antitheft polished rod Fang Ka.
Background technology:
In oil recovery field, oil field, under the driving of great number interests, thief is by the various connecting bolts on the dismounting well head, theft polished rod Fang Ka and bolt.For the molecule theft that avoids theft, the anti-theft device of installing on the existing well head bolt, and existing anti-theft device is unfavorable for applying because reasons in structure exists the problem of anti-theft effect difference.
The utility model content:
In order to solve the problem of existing antitheft polished rod Fang Ka anti-theft effect difference, the utility model provides a kind of antitheft polished rod Fang Ka, and this antitheft polished rod side jig has the characteristics of good anti-theft effect.
The technical solution of the utility model is: this antitheft polished rod Fang Ka comprises polished rod Fang Ka; its special polished rod Fang Ka links to each other half with bolt by screw thread; be with protective sleeve on the bolt step; the protective sleeve upper end is interior by the protecting cover that has been threaded; protecting cover radial hole internal thread is connected with pinning; pinning one end places in the interior annular groove of protective sleeve, and protective sleeve radially has and the corresponding via hole of radial hole, and the protective sleeve top axial has delthyrium.
The positive left-hand thread that matches is arranged in pinning in the such scheme and the radial hole; Radial hole has 2 at least.
The utlity model has following beneficial effect: this antitheft polished rod Fang Ka is because employing is covered with protective sleeve on bolt head; protective sleeve seals by protecting cover; protecting cover is by hiding the structure of pinning locking; utilize protective sleeve and protecting cover blind bolt head, and protective sleeve and protecting cover rotate freely, make thief to rotate; and by hiding pinning locking protecting cover; make thief can't dismantle protecting cover, protected polished rod Fang Ka and bolt, reach the antitheft purpose of polished rod Fang Ka and bolt.This antitheft polished rod side jig has the characteristics of good anti-theft effect thus.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-bolt among the figure, 2-protective sleeve, 3-protecting cover, 4-radial hole, 5-pinning, 6-groove, 7-via hole, 8-polished rod Fang Ka.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing; this antitheft polished rod Fang Ka comprises polished rod Fang Ka 8; polished rod Fang Ka 8 links to each other half with bolt 1 by screw thread; 1 on bolt is with protective sleeve 2 on getting out of a predicament or an embarrassing situation; in protective sleeve 2 upper ends by the protecting cover 3 that has been threaded; protecting cover 3 has 4 radial holes 4; 1 radial hole 4 internal thread is connected with pinning 5; in pinning 5 and the radial hole 4 the positive left-hand thread that matches is arranged; pinning 5 one ends place in the protective sleeve 2 interior annular grooves 6; protective sleeve 2 radially has and radial hole 4 corresponding via holes 7, and protective sleeve 2 top axials have delthyrium.
During actual the use; earlier protective sleeve 2 is enclosed within on 1 on bolt gets out of a predicament or an embarrassing situation; again polished rod Fang Ka 8 half via hole are enclosed within on the bolt 1; again by bolt 1 upper end delthyrium swivel bolt 1; chucking polished rod Fang Ka 8 is threaded with second half polished rod Fang Ka 8; be connected in protecting cover 3 and protective sleeve 2 upper ends by screw thread again; just entering in the radial hole 4 or despining pinning 5 by via hole 7 at last; anti-again or positive rotation pinning 5 behind the rotation certain distance; another termination of pinning 5 is entered in the protective sleeve 2 interior annular grooves 6; finally make protecting cover 3 to rotate, and can not dismantle, thereby realize protecting polished rod Fang Ka and bolt with respect to protective sleeve 2.These antitheft polished rod Fang Ka characteristics are: at first by protective sleeve 2 and protecting cover 31 on bolt is closed, thief can only rotate protective sleeve 2, and can't swivel bolt 1, reaches polished rod Fang Ka 8 purposes that avoid theft.Again by hiding pinning 5 locking protecting covers 3; thief will find the radial hole 4 that is built-in with pinning 5; also want then only to rotate pinning 5 respectively to two directions; could in protective sleeve 2 grooves 6, shift out; thereby the difficulty of increase unlatching; improve anti-theft effect, protected polished rod Fang Ka and bolt, guaranteed the ordinary production of producing well.
