For achieving the above object, the following technical scheme of this utility model offer:
A kind of petroleum drilling and mining is with connecting sleeve pipe, including sleeve body, first connects end, second connects end, female thread, external screw thread and annular rubber ring, described sleeve body is respectively arranged at two ends with the first connection end and second and connects end, connect end by first between two sleeve body and the second connection end is attached, described first connects end is provided with female thread, described second connects end is provided with external screw thread, described female thread and external screw thread match, described first end connecting end and the second connection end is equipped with annular rubber ring, described first connects the half that end thickness is described sleeve body thickness, described second connects the half that end thickness is described sleeve body thickness.
Preferably, also include that annular fixing member and rubber sleeve, described first connection end and second connect and be equipped with annular fixing member on end outer wall, described in two, between annular fixing member, be provided with rubber sleeve.
Preferably, described rubber sleeve is connected the fixing connection of end outer wall with described first.
Preferably, also include that annular is domatic, be provided with annular on rear side of described annular fixing member domatic.
Of the present utility model having the beneficial effect that connects end by being respectively provided with the first connection end and second at sleeve body two ends, convenient is attached by the sleeve pipe of same type；First connection end and second is connected end and is attached by internal and external threads, and is provided with annular rubber ring in the first end connecting end and the second connection end, it is achieved thereby that the effect of double-layer seal；Connect first and on end and the second connection end outer wall, annular fixing member is set, and rubber sleeve is set between interconnective annular fixing member, thus enhance its sealing, reduce its probability being corroded, improve service life；And it is domatic to be provided with annular after annular fixing member, it is possible to make sleeve body in use, more smooth and easy, reduce the damage that the collision of annular fixing member causes.This utility model simple in construction, is completely embedded, and carries smooth and easy, good sealing effect, and anti-corrosion capability is strong, and service life is long.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model；
In figure: 1 sleeve body；2 first connect end；3 second connect end；4 female threads；5 external screw threads；6 annular rubber rings；7 annular fixing members；8 rubber sleeves；9 annulars are domatic.
Detailed description of the invention
This utility model provides a kind of petroleum drilling and mining and connects sleeve pipe, this utility model simple in construction, is completely embedded, carries smooth and easy, good sealing effect, and anti-corrosion capability is strong, and service life is long.
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clear and detailed description, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiment.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
A kind of petroleum drilling and mining as shown in Figure 1 connects sleeve pipe, including sleeve body 1, first connects end 2, second connects end 3, female thread 4, external screw thread 5 and annular rubber ring 6, described sleeve body 1 is respectively arranged at two ends with the first connection end 2 and second and connects end 3, it is attached by the first connection end 2 and the second connection end 3 between two sleeve body 1, described first connects end 2 is provided with female thread 4, described second connects end 3 is provided with external screw thread 5, described female thread 4 and external screw thread 5 match, described first end connecting end 2 and the second connection end 3 is equipped with annular rubber ring 6, described first connects the half that end 2 thickness is described sleeve body 1 thickness, described second connects the half that end 3 thickness is described sleeve body 1 thickness.So after first connects end 2 and the second connection end 3 connects, it is possible to making inside and outside tube wall the most concordant, cleaning is strong.
