Abstract
The utility model discloses a device for taking out a broken pipe fitting, which includes a spanner. One end of the spanner is detachably connected with a connecting column at the tail end of a detaching head; a plane parallel to the axis of the connecting column is at least arranged on the outer side surface of the connecting column body; a spanner is sleeved on the connecting column body through a through hole formed at one end of the spanner and matched with the connecting column body; and a hard regular prismoid-shaped squeezing body is arranged at the front end of the detaching head. The broken pipe fitting can be fast taken out in the ways as follows: inserting the detaching head into the inner hole of the pipe fitting through hammering, pressing and embedding a squeezing body in the wall of the inner hole of the pipe fitting, and rotating the spanner in the reverse direction. The device is suitable for fast detaching pipe fittings broken in a threaded hole.
Description
Technical field
The utility model relates to a kind of instrument that is used to take out the thread part that fractures, and especially relates to a kind of hand-operated tools of pipe joint of fractureing that is used to take out.
Background technology
At present, pipe joint is widely used in various hydraulic pressure, the connection of air pressure and other pipeline, wherein threaded portion is threaded in the respective threads hole, and the root of screw thread is the position that stress is concentrated, therefore moment of torsion is excessive when screwing in or dismantle, or its blank area that exposes is collided, pipe joint is ruptured at the root of its screw thread, and the pipe joint of fracture is because in screwed hole, therefore be difficult to its taking-up, especially its threaded portion produces corrosion after long-term the use, uses common instrument will make taking-up work become very difficult, and does not still have a kind of simple in structure at present, convenient easy-to-use, the specific purpose tool that the pipe joint that fractures can be taken out fast.
The utility model content
The utility model is the problem that is difficult to take out for the pipe joint that solves after the fractureing of existing in the prior art, provides a kind of simple in structure, can take out the pipe joint extractor that fractures of the pipe joint that fractures fast.
To achieve these goals, the utility model is by the following technical solutions: a kind of pipe joint extractor that fractures, comprise spanner, one end of described spanner removably connects with the cylinder that is connected of Tool for detaching tail end, has a plane parallel on the lateral surface of described connection cylinder at least with the joint pin body axis, spanner is socketed on the connection cylinder with the through hole that is connected the cylinder coupling by being located at the one end, and the front end of described Tool for detaching is provided with the positive terrace with edge shape pressing body of hard.Because the pipe joint that fractures is positioned at screwed hole, common instrument is difficult to it is applied moment of torsion, the utility model in use, the small end of the positive terrace with edge shape pressing body front of hard on the Tool for detaching is inserted the pipe joint endoporus that fractures and knock with iron hammer, make the big end in pressing body back push and embed the hole wall of the pipe joint endoporus that fractures just like the seamed edge of cutting edge, thereby the pipe joint that fractures is socketed on the pressing body as box spanner, at this moment, the backward rotation spanner can be delivered to the pressing body of moment of torsion by Tool for detaching on the pipe joint that fractures, thereby the pipe joint that fractures is screwed out, because spanner is detachably to be socketed in to connect on the cylinder, therefore, when the withdrawal space limited and continuously during rotating spanner, desirable lower ejector lever, be socketed in again on the connection cylinder after getting back to original position, rotate a low-angle then, repeat said process and the pipe joint that fractures can be taken out.Because the external side of joint pin is provided with at least one plane parallel with the joint pin body axis, so can guarantee spanner and connect between the cylinder can not produce relative rotation, thereby the driving torque of spanner is delivered on the pressing body reliably, and the pipe joint reverse rotation that final drive fractures is taken out it.In addition, by changing dismountable Tool for detaching, the pipe joint that the detachable plurality of specifications of the utility model fractures.
As preferably, described pressing body is positive three terrace with edges, thereby make the madial wall of the cutting edge of pressing body each seamed edge when the pipe joint that insertion fractures perpendicular to pipe joint, the angle of seamed edge two sides formation simultaneously is little, both helped the hole wall that seamed edge pushed and embedded the pipe joint endoporus that fractures, and can avoid pressing body again and fracture skidding between the pipe joint endoporus.
As preferably, described pressing body is positive truncated rectangular pyramids, thereby make the madial wall of the cutting edge of pressing body each seamed edge when the pipe joint that insertion fractures perpendicular to pipe joint, the cross section of pressing body is bigger simultaneously, both helped the seamed edge extruding and embedded the hole wall of pipe joint endoporus that fractures, but made the pressing body transfer larger torque again.
As preferably, the angle of described pressing body lateral surface and its axial line is 2 °～6 °, both help pressing body and inserted the pipe joint endoporus that fractures, can guarantee that again pressing body has the seamed edge extruding of sufficient length and embeds the pipe joint endoporus hole wall that fractures, and takes out the pipe joint that fractures thereby can transmit bigger moment of torsion.
As preferably, described pressing body and Tool for detaching are affixed to be integral, the hardness of pressing body is HRC45～HRC55, thereby the seamed edge of guaranteeing pressing body can push more conveniently and embed the pipe joint endoporus hole wall that fractures, and can reduce the wearing and tearing of pressing body simultaneously, prolongs its service life, in addition, affixed again being integral after pressing body and Tool for detaching be separately made, the processing of head for convenience detach reduces its manufacturing cost.
As preferably, described connection cylinder is a four-prism, but makes spanner and connect transfer larger torque between the cylinder, simultaneously convenient wrench from several angle positions be connected the cylinder socket, make things convenient for the use of the utility model when the withdrawal space is limited.
As preferably, described connection cylinder is positive six prisms, when guaranteeing to transmit than high pulling torque between spanner and the connection cylinder, convenient wrench from a plurality of angle positions be connected the cylinder socket, make things convenient for the use of the utility model when the withdrawal space is limited, in addition, the connection cylinder of positive six prisms can cooperate with general box spanner, thereby enlarges its scope of application.
Therefore, the utlity model has following beneficial effect: (1) effectively is delivered on the pipe joint that fractures by the moment of torsion of Tool for detaching with spanner, can take out the pipe joint that fractures fast; (2) Tool for detaching is replaceable, adapts to the pipe joint of dismounting plurality of specifications; (3) part is few, and is simple in structure, and production cost is low.
