Abstract

The invention provides a fracture extractor for an internal thread, which is characterized in that a coniform mandrel is arranged on the fracture extractor; screw threads are formed in the middle of the coniform mandrel; the coniform mandrel is sequentially sheathed with a tensioning piece, a gasket and a nut; the tensioning piece comprises an expansion pipe; and a screwhead is fixedly arranged at one end of the expansion pipe. When in use, the assembled extractor is inserted in the fractured internal thread, the mandrel is clamped through a tool, and then the nut is screwed through a wrench to lead the mandrel to move outwards, so that the tensioning piece is led to tightly stick to the fractured internal thread, and then the fractured internal thread can be taken out together with the extractor after the screwhead of the tensioning piece is screwed. The fracture extractor for the internal thread has a simple structure and is convenient to operate, the fractured internal thread can be taken out easily, no damages to a pipeline can be caused, and the time is saved.

Description

Internal thread fracture extractor
Technical field
The present invention relates to a kind of common tool, particularly a kind of internal thread fracture extractor.
Background technology
In normal water power maintenance process, some pipe fittings are long service time, and the dead phenomenon of rust is arranged.The water power worker runs into the problem that internal thread is twisted into two parts easily in the maintain and replace process.The internal thread of twisting into two parts takes out in pipeline, often will adopt a lot of methods, wastes time and energy, and also is easy to damage pipeline.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, provides a kind of simple in structure, easy to use, is easy to take out the internal thread fracture extractor of the internal thread of fracture.
Technical problem to be solved by this invention is to realize by following technical scheme.The present invention is a kind of internal thread fracture extractor, be characterized in: be provided with the taper mandrel, the middle part of taper mandrel is provided with screw thread, is set with tensioner part, pad and nut successively on the described taper mandrel, described tensioner part comprises expansion tube, is fixed with screw terminal at an end of expansion tube.
Compared with prior art, the present invention is set with tensioner part, pad and nut on the taper mandrel.During use the internal thread fracture extractor that assembles is inserted in the internal thread of fracture, use the tool holder mandrel, use the wrench nutting again, mandrel is moved outward, thereby make the tensioner part be adjacent to the internal thread of fracture, twist the screw terminal of tensioner part so again, the internal thread of fracture will come out together with extractor.It is simple in structure, and is easy to operate, can be easy to take out the internal thread of fracture, and not damage pipeline, has saved the time.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
Following with reference to accompanying drawing, further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not constitute restriction to its right.
Embodiment 1.With reference to Fig. 1.A kind of internal thread fracture extractor, be provided with taper mandrel 1, the middle part of taper mandrel 1 is provided with screw thread, is set with tensioner part, pad 4 and nut 5 on the described taper mandrel 1 successively, described tensioner part comprises expansion tube 2, is fixed with screw terminal 3 at an end of expansion tube 2.
During enforcement, the internal thread fracture extractor that assembles is inserted in the internal thread of fracture, tool using clamps taper mandrel 1, use wrench nutting 5 again, make that mandrel 1 is outer to be moved, the tapering of mandrel 1 will strut the expansion tube 2 of tensioner part, thereby makes the expansion tube 2 of tensioner part be adjacent to the internal thread of fracture, twist the screw terminal 3 of tensioner part so again, the internal thread of fracture will come out together with extractor.
