The upper/lower terminal of the pump barrel is machined with box thread respectively；
The upper box cupling is size header structure, and the wherein connecting portion on enlarged head and small head is provided with step；The enlarged head
External diameter no more than pump barrel external diameter and inner surface be machined with box thread, the small head exterior surface is machined with male thread；It is described
The box thread of pump barrel upper end is coordinated by screw thread realizes that screw thread is connected with the male thread of the upper box cupling, and the pump barrel
The step of upper end and the upper box cupling against；
The lower box cupling is size header structure, and the wherein connecting portion on enlarged head and small head is provided with step；The enlarged head
External diameter no more than pump barrel external diameter and inner surface be machined with box thread, the small head exterior surface is machined with male thread；It is described
The box thread of pump barrel lower end is coordinated by screw thread realizes that screw thread is connected with the male thread of the lower box cupling, and the pump barrel
The step of bottom and the lower box cupling against；
The small head of the lower box cupling is provided with runner plate, and the translot that twice are in 90 degree is machined with the runner plate.
Further, the upper box cupling and the external diameter of lower box cupling enlarged head are consistent with the external diameter of pump barrel, the upper box cupling,
Pump barrel and lower box cupling are sequentially connected as the overall consistent oil well pump of external diameter.
Further, small head of the upper box cupling with lower box cupling at step be machined with least together with annular groove,
Sealing ring is installed, the upper box cupling and lower box cupling pass through the sealing ring and the upper and lower end of pump barrel respectively in the annular groove
Realize that sealing coordinates.
Further, the annular groove is juxtaposed twice.
Compared with prior art, the beneficial effects of the utility model are：One improve after the small supporting oil well pump of external diameter most
Big external diameter is the external diameter of pump barrel, the outside dimension of oil well pump is reduced, so that the smooth G.I.H of oil well pump；With box cupling at present
90 degree of translot being provided with designs compared to existing orifice-plate type, substantially increases fluid flow, and then improve oil well pump
Operating efficiency.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1-5, a kind of small supporting oil well pump of external diameter, including pump barrel 2 and its both ends be connected through a screw thread it is upper
Box cupling 1 and lower box cupling 3；The upper/lower terminal of pump barrel 2 is machined with box thread respectively；
Upper box cupling 1 is size header structure, and wherein the connecting portion on enlarged head 8 and small head 9 is provided with step 4；Outside enlarged head 8
Footpath is consistent with the external diameter of pump barrel 2 and enlarged head inner surface is machined with box thread, and the small outer surface of head 9 is machined with male thread, microcephaly
Portion 9 is machined with least twice annular groove 5, and sealing ring is provided with annular groove 5；The box thread of the upper end of pump barrel 2 is coordinated by screw thread
