Abstract

The utility model discloses an adjustable threading tool of which the main structure is provided with an outer casing and an inner casing which do relative movement via screw thread, wherein the outer casing is provided with an inner cone surface and a spacing boss, and the inner casing is of a shape being convex at two ends and concave at the middle and is provided with a thread winding detention of which one end is provided with a thread winding having a same taper of the inner cone surface and the other end is made into an elbow shape to contact with a spring disposed inside a spring base of the inner casing. The utility model is capable of changing inner casings according to different diameters of processed pipes and making screw thread at two ends of pipes of any length, thereby providing convenience for on-site processing and increasing working efficiency.

Description

Adjustable mantle fiber instrument

The utility model relates to a kind of mantle fiber instrument.

At present, the mantle fiber instrument that people use has two classes, and a class is adjustable mantle fiber instrument, can only processing length be the screw thread of the above pipe of 16cm; Another kind of is fixing mantle fiber instrument, can only processing length be the screw thread of the above length pipe of 7cm.The shortcoming of existing mantle fiber instrument is to be that 7cm is with interior pipe two ends machining screw in length directly; If desired at 7cm with interior pipe two ends machining screw, just must make two one start screw pipes, then two not had back-to-back the welding in position of screw thread, the deficiency of doing like this is inconvenient on-the-spot processing, and time-consuming, reduced operating efficiency.

The purpose of this utility model is intended to overcome above-mentioned shortcoming, provide a kind of can be to the adjustable mantle fiber instrument of the pipe two ends machining screw of random length.

For achieving the above object, the utility model adopts following solution: comprise outer sleeve and inner sleeve, the outside of outer sleeve is provided with handle, it is characterized in that: the inside of outer sleeve is provided with forward and backward thread segment, be provided with inner conical surface between the forward and backward thread segment, the small end of inner conical surface is provided with positive stop lug boss; The outside of inner sleeve is recessed shape in the middle of the two ends projectioies, the face of two ends projection be provided with outer sleeve in the supporting screw thread of forward and backward thread segment, middle recessed position is provided with some Pick Wire button tooth through holes and the spring base supporting with it; The end face of Pick Wire button tooth one end is provided with the Pick Wire identical with the tapering of outer sleeve inner conical surface, and the other end is converted into the elbow shape; Pick Wire button tooth is installed in the through hole of inner sleeve, and the elbow part of Pick Wire button tooth contacts with the spring of setting in the inner sleeve spring base.

Above-mentioned adjustable mantle fiber instrument is characterized in that: the bossing that matches with outer sleeve rear thread section that described inner sleeve is provided with is dismountable inner sleeve end cap, is fixed as one by bolt and inner sleeve.

Above-mentioned adjustable mantle fiber instrument is characterized in that: the main body of described Pick Wire button tooth through hole and Pick Wire button tooth is square.

The course of work of the present utility model is: pipe to be processed is put in the inner sleeve of the present utility model, buckle on the tooth in Pick Wire the position, threaded portion that pipe will be processed, people's rotating handles then, outer sleeve is moved to the left, inner sleeve then moves right, the Pick Wire tooth-knocking rod under the pressure of outer sleeve inner conical surface compressing, cusp can be on pipe machining screw, when Pick Wire button tooth is run into positive stop lug boss, promptly process the required screw thread of pipe one end; People are the reverse rotation handle again, takes out processed pipe, and pipe is oppositely put in the inner sleeve again, buckles on the tooth in Pick Wire by the position, threaded portion that Len req will be processed pipe, can process the required screw thread of the pipe other end; Take out the pipe of being processed at last, use saw sawed-off, just can obtain two screw thread pipes of the length of wanting.

Compared with prior art, the utlity model has following advantage:

1, because the utility model has designed outer sleeve and the inner sleeve of doing relative motion by screw thread, be provided with inner conical surface and positive stop lug boss in the outer sleeve, Pick Wire is installed on the inner sleeve buckles tooth, so the utility model can be given the pipe two ends machining screw of random length, make things convenient for on-the-spot processing, improved operating efficiency.

2, because inner sleeve of the present utility model and inner sleeve end cap are one by several bolted, so the utility model can be convenient for changing the Pick Wire button tooth of different pitch.

3, the utility model can be changed the inner sleeve of different size according to the size of institute's pipe processing diameter.

Below in conjunction with drawings and Examples the utility model is described in further detail.
