Abstract
The utility model discloses a sealing packing of a smooth sucker rod, which comprises a second half (1) and a first half (2) and is characterized in that the sealing packing has a cylindrical structure which is formed by inserting a dovetail bulge arranged on the front half (2) into a dovetail groove on the second half (1); a semicircle orifice (6) on the second half and a semicircle orifice (6) on the first half form a through-hole of a polished rod; and a plurality of annular hole cavities are formed in a plurality of grooves (3) in the semicircle orifice (6). The sealing packing has the advantages of convenient replacement and operation, good sealability, long service life and short period of oil well stop, and can improve production time efficiency of oil well, and increase crude production.
Description
Technical field
The utility model relates to oil field machinery oil wellhead polish rod seal, particularly is a kind of oil pumping polish rod sealed packing.
Background technology
At present, in the oil field machinery oil manufacturing process, the drive sucker rod that pumps, deep well pump by oil pumping polish rod are extracted into ground with crude oil, the sealed packing of oil pumping polish rod not only requires good sealing, has high abrasion resistance again, and change conveniently, existing packing adopts loop configuration, must it be cut 30-45 ° of otch clockwise with hacksaw during replacing, and otch staggers 120 °-180 °, it is very inconvenient to change the packing operation, it is long that oil well stops the well time, influence crude output, therefore, prior art can not address the above problem preferably.
The utility model content
The purpose of this utility model is exactly at above-mentioned weak point, designs a kind of oil pumping polish rod sealed packing, and it is very inconvenient to change the packing operation in the solution prior art, and it is long that oil well stops the well time, influences the problem of crude output.
The purpose of this utility model is realized by following technical proposals.
The utility model comprises later half, preceding half; It is characterized in that: described oil pumping polish rod sealed packing is columnar structured, the dovetail groove that is inserted on later half by the dovetail tangs on half before being located at is formed by connecting, semicircle orifice on the semicircle orifice on later half and preceding half forms the polished rod through hole, several groove that is positioned at semicircle orifice forms several circular bore, so that storage grease, lubricated polished rod, the application life of improving packing.
It is corresponding with dovetail groove that later half and preceding half both sides in the above-mentioned oil pumping polish rod sealed packing can also be established a dovetail tangs respectively, intersects to cooperate.
According to the oil pumping polish rod sealed packing that such scheme is made, changes easy to operate, good airproof performance, long service life, it is short that oil well stops the well time, rate when improving oil well production, increase crude output.
Description of drawings

The attached TV structure schematic diagram of Fig. 2-the utility model.
In the accompanying drawing, 1. later half, 2. before half, 3. groove, 4. dovetail tangs, 5. dovetail groove, 6. semicircle orifice.
The specific embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further elaborated:
A kind of oil pumping polish rod sealed packing of the utility model comprises: later half 1, preceding half 2; It is characterized in that: described oil pumping polish rod sealed packing is columnar structured, the dovetail groove 5 that is inserted on later half 1 by the dovetail tangs 4 that is located on preceding half 2 is formed by connecting, semicircle orifice 6 on the semicircle orifice 6 on later half 1 and preceding half 2 forms the polished rod through hole, and several groove 3 that is positioned at semicircle orifice 6 forms several circular bore.
It is corresponding with dovetail groove 5 that in the utility model later half 1 and preceding half 2 both sides can also be established a dovetail tangs 4 respectively, intersects to cooperate.
Claims (2)
1, a kind of oil pumping polish rod sealed packing comprises: later half (1), preceding half (2); It is characterized in that: described oil pumping polish rod sealed packing is columnar structured, the dovetail groove (5) that is inserted on later half (1) by the dovetail tangs (4) on half (2) before being located at is formed by connecting, semicircle orifice (6) on semicircle orifice (6) on later half (1) and preceding half (2) forms the polished rod through hole, and several groove (3) that is positioned at semicircle orifice (6) forms several circular bore.
