Specific embodiment

It is detailed with reference to attached drawing in the part in order to clearly illustrate the above-mentioned purpose of the utility model, feature and advantage Describe bright specific embodiment of the present utility model in detail.Other than each embodiment described in this part, the utility model It also is able to implement by other different modes, in the case of without prejudice to the spirit of the present invention, those skilled in the art It can be correspondingly improved, deform and replace, therefore the utility model is not limited by specific embodiment disclosed in the part.This The protection domain of utility model patent should be subject to claim.

The utility model provides a kind of tool for the internal workpiece that dismounting is threaded togather and external workpiece, please With reference to figure 1, Fig. 1 is the knot of the first embodiment of the tool provided by the utility model for being used to dismantle internal workpiece and external workpiece Composition.

In the first embodiment, which includes grip part and axis body 10, and grip part includes bluff body 30 and cylinder 20, flat Flat body 30, cylinder 20, axis body 10 are sequentially connected along the axial direction of the axis body 10.Grip part holds for operator, and axis body 10 is used It is contacted in the internal workpiece with threaded connection and dismantles the internal workpiece from external workpiece.Grip part and axis is described in detail below Body 10.

Axis body 10

In this embodiment, axis body 10 has the rib structure 11 radially protruded, and the rib structure 11 is along axis body 10 Axially extending, rib structure 11 is succeedingly formed along the axial direction of axis body 10, and circumferential along axis body 10 forms three rib structures 11 altogether, And the radial dimension of the one end of axis body 10 from close to one end of grip part to far from grip part tapers into, so as to entire axis body 10 are formed as triangular platform, and the triangular platform is using one end of the close grip part of axis body 10 as bottom.

Grip part

In this embodiment, grip part includes cylinder 20 and bluff body 30, the axis of cylinder 20 and bluff body 30 along axis body 10 To connection, cylinder 20 is connected to axis body 10 and for being held for operator.Cylinder 20 is cylinder, one end and triangular platform shape Axis body 10 connects, and the other end is connect with bluff body 30.Bluff body 30 forms an end of the tool, which is used to supply Clamping device (such as spanner etc.) clamps.

The internal workpiece and the tool of external workpiece for dismounting threaded connection in the structure first embodiment below Production method.

First, the round steel of predetermined length (taking 140mm in this embodiment) is taken；

Then, the suitable length section (taking 50mm in this embodiment) of close one end of the round steel is polished using three faces Tip simultaneously is polished to form triangular platform by technique；

Finally, the suitable length section (taking 12mm in this embodiment) of the close other end of round steel is polished using two sides Technique forms bluff body 30.

In this way, the section (length is 78mm in this embodiment) between bluff body 30 and axis body 10 forms above-mentioned cylinder 20。

Be described below this for dismantle be threadedly coupled internal workpiece with outside workpiece tool application method.

When the internal workpiece of threaded connection is broken in external workpiece and usual manner can not be used to screw out, operator holds It holds cylinder 20 tool is extend into inside internal workpiece, one end (i.e. tip) that the tool specifically is had axis body 10 is inserted into To internal workpiece；Then, hand hammer percussion is sentenced in one end (i.e. flush end) with bluff body 30 of the tool, it is therefore an objective to so that axis Body 10 can be securely inserted into internal workpiece so that rib structure 11 is embedded into the inner wall of internal workpiece and internal workpiece shape It is integrally formed；Flush end finally is clamped using clamping device, along the reverse rotation of the screw-in direction of threaded connection (for example, inside Portion's workpiece is in the case of entering external workpiece by rotating clockwise, to rotate clamping device counterclockwise), at this point, axis body 10 With screwing out external workpiece together with internal workpiece, so as to complete the dismounting of internal workpiece and external workpiece.

In this embodiment, which is made of carbon steel, not only with preferable hardness, also with cheap price.

As described above, the tool has grip part and axis body 10, and with the rib structure 11 protruded from axis body 10, the tool Be formed as whole with internal workpiece by the rib structure 11 of axis body 10, in this way when rotating the tool except internal workpiece, The tool can drive internal workpiece to rotate together with, then arrange in pairs or groups just can be by internal workpiece from external work with appropriate direction of rotation Part is removed.

Rib structure 11 helps to be formed in succession the intensity of preferable rib structure 11, and internal workpiece is embedded in rib structure 11 And when rotating together with, rib structure 11 is not easy to break, ensures to remove the reliability of work.

Axis body 10 is formed as triangular platform, so as to which with more tapering one end, which has preferable be oriented to Effect so that axis body 10 is more easy to stretch into internal workpiece.

The bluff body 30 that grip part is formed clamps convenient for clamping device, in the step of internal workpiece is screwed out external workpiece It saves manpower and improves dismounting efficiency.

The each section of the tool should have suitable length, for example the length of axis body 10 should be appropriate, is otherwise not easy to protect Card tool forms firmness during entirety with internal workpiece；The length of cylinder 20 should be appropriate, is otherwise unfavorable for operating personnel It holds；The length of bluff body 30 should be appropriate, otherwise may waste the labor and materials of tool or cannot provide effective clamping face.

In unshowned other embodiment, the length of axis body 10 may be at the range of 40mm to 55mm, the length of cylinder 20 Degree may be at the range of 70mm to 85mm, and the length of bluff body 30 may be at the range of 10mm to 14mm.

The utility model is related to internal workpiece and external workpiece be pipe fitting.

Although above to provided by the utility model for the internal workpiece that dismounting is threaded togather and external workpiece Tool be described in detail, but also need to illustrate the following：

1. the rib structure of axis body can in succession be formed not along the axial direction of axis body, and can be intermittently formed, as long as Rib structure axially extends the inner wall so as to ensure to be embedded in internal workpiece when axis body stretches out internal workpiece.

2. grip part can only have for the part held without the bluff body for clamping device clamping, as long as its It can be operated by operator and axis body is driven to stretch into internal workpiece.

3. the number of rib structure is unrestricted, can be 2,4 or more.

4. axis body can also be prism or along axis body several rib structures of circumferentially-spaced arrangement so as to form axis body For radial structure.

5. the tool can also be made of stainless steel.

Above each embodiment is without prejudice to can arbitrarily be combined in the range of the spirit of the present invention.Succinctly to rise See, there is omitted herein the description of parts thereof, however the parts thereof should all be interpreted as that the prior art can be used real It applies.
