Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, this utility model is done detailed description further, but embodiment of the present utility model is not limited to this.
Embodiment 1:
The oil drill rocker of good stability, including multiple poles, these poles are sequentially connected according to the connected mode of the upper end that the lower end of a upper pole connects next root pole.
As shown in Figure 1, described pole includes the body of rod 1, is welded on the top connection 2 of the body of rod 1 upper end, is welded on the lower contact 3 of the body of rod 1 lower end, all offering through hole in described top connection 2, the body of rod 1, lower contact 3, three through holes are coaxial and the central axes of axis and the body of rod 1, it is simple to liquid flows through.
Described top connection 2, lower contact 3 are all in hollow cylindrical, and top connection 2 is identical with the external diameter of the body of rod 1, and the external diameter of the body of rod 1 is more than the external diameter of lower contact 3, and the internal diameter of lower contact 3 is identical with the internal diameter of the through hole in the body of rod 1, and the internal diameter of top connection 2 is more than the internal diameter of lower contact 3.
The outer wall of lower contact 3 is provided with external screw thread, is provided with the female thread that the external screw thread with lower contact 3 outer wall matches in the through hole of top connection 2, makes the lower contact 3 of a pole be threaded in the through hole of top connection 2 of next root pole.
Described top connection 2 offers the first spacing hole 21, described lower contact 3 offers the second spacing hole 31, the axis of described first spacing hole 21 and the second spacing hole 31 is each perpendicular to the central axis of the body of rod 1, and namely the axis direction of the first spacing hole 21 and the second spacing hole 31 is horizontal direction.It is additionally provided with positive stop strip 4 in described first spacing hole 21；Being provided with female thread in described first spacing hole 21 and the second spacing hole 31, described positive stop strip 4 is provided with external screw thread, the first spacing hole 21 arrives the distance bottom its place lower contact 3 to the distance of the bottom of its place top connection 2 equal to the second spacing hole 31；Make positive stop strip 4 can be simultaneously connected with next root pole top connection 2 the first spacing hole 21 and on a pole lower contact 3 the second spacing hole 31 in.
The method of attachment of adjacent two poles is: is first outwards screwed out by the positive stop strip 21 of the top connection 2 of next root pole, exits the through hole of top connection 2；Then the lower contact 3 of a upper pole is screwed in the through hole of top connection 2 of next root pole, until the bottom of the lower contact 3 of a upper pole is concordant with bottom the top connection 2 of next root pole, now the first spacing hole 21 and the second spacing hole 31 align, then positive stop strip 4 is screwed to through hole central axial direction, until positive stop strip 4 screws in the second spacing hole 31, such positive stop strip 4 is just simultaneously connected with in the first spacing hole 21 and the second spacing hole 31, it is possible to avoids the lower contact 3 of a pole to produce relative rotation with the top connection 2 of next root pole and brings unstability.In the present embodiment, connecting through threaded and installing positive stop strip 4 two ways additional and ensure that the stability of connection between pole.
Embodiment 2
On the basis of embodiment 1, the oil drill rocker of the good stability in the present embodiment also carries out improving as follows:
It is additionally provided with the first wear-resistance protective sleeve 5 outside described top connection 2, the bottom outer wall of the described body of rod 1 is additionally provided with the second wear-resistance protective sleeve 6, the first spacing hole 21 position is just also being offered a hole by the first wear-resistance protective sleeve 5, it is simple to operation positive stop strip 4.
Also being welded with the 3rd wear-resistance protective sleeve 7 on the middle part outer wall of the described body of rod 1, on described 3rd wear-resistance protective sleeve 7, the circumference along the body of rod 1 is further opened with annular groove 71, and this annular groove 71 is used for lifting pole.
First wear-resistance protective sleeve the 5, second wear-resistance protective sleeve the 6, the 3rd wear-resistance protective sleeve 7 adopts rich chromium cast iron to make, and its abrasion resistant effect is very good.The thickness of first wear-resistance protective sleeve the 5, second wear-resistance protective sleeve the 6, the 3rd wear-resistance protective sleeve 7 is 10cm, and can adequately protect pole, is unlikely to again too thick.Too thick, increase the weight of pole, give transport, use and all cause bigger burden；Too thin, wear and tear too fast, reduce pole service life.
Embodiment 3:
On the basis of embodiment 1 or embodiment 2, pole is also carried out improving as follows by the present embodiment:
Being further opened with a ring groove bottom the described body of rod 1, be provided with sealing ring 8 in annular groove, the effect of sealing ring 8 is mainly used in the liquid preventing from flowing through pole and spills from the junction of adjacent two poles.
Below being only preferred implementation of the present utility model, protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, should be regarded as protection domain of the present utility model.
