Abstract
The utility model relates to an antitheft bolt for motor of pumping unit which is created mainly to solve the problem that the existing motor is prone to be stolen. The utility model is characterized in that a step(4) is provided in a bolt head(1), a protective jacket(5) is mounted on the step(4), two or more notches(6) are provided evenly at the axial direction on the bolt head(1); a screw nut(2) with an internal step(7) is connected with the other end of a bolt(3), a protective jacket(8) is mounted on the step(7), and two or more blind holes(9) are provided evenly at the axial direction on the outside end surface of a screw nut(2). The antitheft bolt for motor of pumping unit has the advantages of good antitheft effect and simple structure.
Description
Technical field:
The utility model relates to the used bolt of pumping-unit motor, especially pumping-unit motor anti-theft bolt in the oil recovery field, oil field.
Background technique:
In oil recovery field, oil field, the power on the pumping unit is generally motor, and motor adopts plain bolt to fix more.In recent years; because prior motor is to use plain bolt to fix; no anti-theft measure; the stolen phenomenon of motor is also relatively more serious, and under the unserviced situation of pumping unit, thief can disassemble motor just with general tool and buy; so just cause the loss of state-owned assets; shutdown of pumping machine, oil recovery well stops production, and influences ordinary production.
The model utility content:
In order to overcome the existing easily stolen deficiency of motor, the utility model provides a kind of pumping-unit motor anti-theft bolt, and this pumping-unit motor anti-theft bolt has good anti-theft effect and characteristic of simple structure.
The technical solution of the utility model is: this pumping-unit motor anti-theft bolt comprises an end strap bolt hook bolt and a nut; stage is arranged in the bolt head; be covered with protecting jacket on the stage; axially at least evenly have 2 gap around the bolt head; the bolt the other end is connected with the nut that the inner has stage; be covered with protecting jacket on the stage, the nut exterior edge face axially is evenly distributed with 2 blind holes at least.
Gap in the such scheme is 4; Blind hole is 4.
The beneficial effect that the utlity model has is: this pumping-unit motor anti-theft bolt because of being covered with the protecting jacket that can rotate arbitrarily at bolt head and nut, has only the special tool of use bolt could be rotated owing to adopted such scheme.So thief utilizes general tool can't dismantle the bolt of fixed electrical machinery, thereby solved the generation of the stolen phenomenon of motor, guaranteed to produce and normally carry out.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-bolt head among the figure, 2-nut, 3-bolt, 4-stage, 5-protecting jacket, 6-gap, 7-stage, 8-protecting jacket, 9-blind hole.
Embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1; this pumping-unit motor anti-theft bolt comprises an end strap bolt head 1 bolt 3 and nut 2; stage 4 is arranged in the bolt head 1; be covered with protecting jacket 5 on the stage 4; axially evenly have 4 gap 6 around the bolt head 1; bolt 3 the other ends are connected with the nut 2 that the inner has stage 7, are covered with protecting jacket 8 on the stage 7, and nut 2 exterior edge faces axially are evenly distributed with 4 blind holes 9.
During actual the use; at first protecting jacket 5 is enclosed within on the bolt head 1; bolt head 1 is covered; and then bolt 3 is penetrated in the hole of motor base, secondly protecting jacket 8 is enclosed within on the bolt 3, with special tool nut 2 is locked at last; because of protecting jacket 5 and protecting jacket 8 cover bolt head 1 and nut 2 respectively; and free to rotate, can only rotate protecting jacket 5 and protecting jacket 8 with general tool, have only the special tool of use nut could be rotated.No special tool is can't rotating bolt head 1 and nut 2, thereby state-owned assets have been protected in the generation that has solved the stolen phenomenon of motor, guarantees that pumping unit normally moves, and guarantees normally carrying out of oil recovery well.This pumping-unit motor anti-theft bolt has good anti-theft effect and characteristic of simple structure thus.
Claims (3)
1, a kind of pumping-unit motor anti-theft bolt, the bolt (3) that comprises a nut (2) and an end strap bolt head (1), it is characterized in that: stage (4) is arranged in the bolt head (1), be covered with protecting jacket (5) on the stage (4), bolt head (1) axially at least evenly has 2 gap (6) all around; Bolt (3) the other end is connected with the nut (2) that the inner has stage (7), is covered with protecting jacket (8) on the stage (7), and nut (2) exterior edge face axially is evenly distributed with 2 blind holes (9) at least.
2, pumping-unit motor anti-theft bolt according to claim 1 is characterized in that: gap (6) is 4.
