Abstract

The utility model provides an anticreep oil union, by body 1, unlocking sleeve 2, screw 3, jump ring 4, spring 5, baffle 6, overcoat 7, the first 8 of oil union, keep off the groove 9 and constitute, the utility model discloses owing to adopt the body to pass through the screw precession overcoat, its lower part is connected with the first of oil union, and slotted on the body, its inslot has the jump ring, is equipped with the spring in the jump ring, and the screw passes through the fixed jump ring of baffle, spring on the body, has on the overcoat keep off the groove and cooperate with the jump ring. When the pipelines are connected, the anti-tripping device can effectively prevent tripping, and is particularly applied to the connection of soft and hard pipelines in oil well construction. The utility model discloses simple structure is practical, and is with low costs, guarantees connecting line safe and reliable conscientiously, has better popularization application prospect.

Description

A kind of Anti-deoiling coupling
Technical field:
The utility model relates to the downhole tool that uses on a kind of oilfield, particularly a kind of Anti-deoiling coupling.
Background technology:
At present, in the construction of oil field, when vehicle pipelines such as pump truck are connected with oil pipeline, generally use the oily ninth of the ten Heavenly Stems, but oil can't prevent the counter-rotating dropout ninth of the ten Heavenly Stems after the connection now, has bigger potential safety hazard, special when the connection of transformation pipeline, bigger accident just takes place easily in case thread off.
Summary of the invention:
The purpose of this utility model is to provide a kind of Anti-deoiling coupling, and it can effectively prevent the dropout that pipeline connects, and connecting line is safe and reliable, can eliminate safe hidden trouble.
The utility model is to realize like this, it is by body (1), separate lock tube (2), screw (3), jump ring (4), spring (5), baffle plate (6), overcoat (7), oil head in the ninth of the ten Heavenly Stems (8), retaining groove (9) is formed, in body (1) outside by screw thread with separate lock tube (2) and be connected, body is by screw thread precession overcoat (7), its underpart is connected with oil head in the ninth of the ten Heavenly Stems (8), on body (1), groove is arranged, jump ring (4) is arranged in its groove, spring (5) is housed in the jump ring (4), screw (3) passes through fixedly jump ring (4) of baffle plate (6), spring (5) has retaining groove (9) and cooperates with jump ring (4) on body (1) on overcoat (7).
In the construction of oil well, pipeline one end connects oil head in the ninth of the ten Heavenly Stems, and the other end connects body, at this moment, separate lock tube and be in the precession state, push down jump ring, jump ring can not be ejected, during connection, oil head in the ninth of the ten Heavenly Stems is contained in the overcoat, body passes through in the screw thread precession overcoat, and compresses oil head in the ninth of the ten Heavenly Stems, simultaneously, unclamp and separate the ejection of lock tube jump ring, enter in the retaining groove, cause overcoat and body not to relatively rotate, guarantee not release, do not thread off, guarantee safety thereby guarantee to connect.
The utility model is owing to adopt body by screw thread precession overcoat, and its underpart is connected with oil head in the ninth of the ten Heavenly Stems, and groove is arranged on body, in its groove jump ring is arranged, spring is housed in the jump ring, and fixedly jump ring, spring have retaining groove and cooperate with jump ring on body screw on the coat by baffle plate.When pipeline connected, it can effectively prevent to thread off, and was applied to the connection of soft, the hard tube line in the well construction especially.Simple and practical, cost is low, guarantees that conscientiously connecting line is safe and reliable, has popularizing application prospect preferably.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with attached the utility model is further specified.
The specific embodiment
As shown in the figure, the utility model by body 1, separate lock tube 2, screw 3, jump ring 4, spring 5, baffle plate 6, overcoat 7, oil ninth of the ten Heavenly Stems 8, retaining groove 9 is formed, in body 1 outside by screw thread with separate lock tube 2 and be connected, body is by screw thread precession overcoat 7, and be connected its underpart and the oily ninth of the ten Heavenly Stems 8, on body 1 groove arranged, jump ring 4 is arranged in its groove, spring 5 is housed in the jump ring 4, and fixedly jump ring 4, spring 5 have retaining groove 9 and cooperate with jump ring 4 on body 1 on overcoat 7 by baffle plate 6 for screw 3.
