Description

A kind of telescopic jig

Technical field

The utility model belongs to field of mechanical technique, is related to a kind of wiring on automobile aid, and in particular to one kind can stretch Contracting tool.

Background technology

Automotive wire bundle is the main body of vehicle signal transmission, is played the role of in Automobile Design and in very important.Vapour Vehicle wire harness is main to be made up of electric wire, the contact of metal material, connector, wrapping fixture.In automobile assembling, in order to It is easy to fixation, installation and the subsequent maintenance of automotive wire bundle, it is necessary to electric wire is tied up bunchy, it is so both attractive in appearance neat, and safety can Lean on.And during the bundle that ties in online, the size of wire harness should be ensured, consider that the connection between electrical equipment is closed with distance again System, make numerous electric wires keep it is neat, beneficial to wrapping, this is accomplished by installing the tool tied up beneficial to wire harness, positioned.In the market The most upper end of automotive wire bundle tool be ailhead, lower end is fixed on buck plate, and electric wire is positioned at the nail on tool when tying up In head, directly wrapping after line is sequenced.Although this kind of wire harness tool simple structure, convenient and practical.But it is past at the end of wrapping It is past to need lifting wire harness to be wrapped up, and during winding displacement, because the length of wire harness has all been set in advance, so wire harness Can be relatively tighter, and the ailhead of wire harness tool is integrally fixed on tool, it is impossible to arbitrarily rotate, so wire harness is not easy to be raised Come, cause wire harness to wrap up inconvenience, or even occur breaking wire harness, and then have impact on the further raising of production efficiency.

The content of the invention

The purpose of this utility model is to provide a kind of telescopic jig, to solve problems of the prior art.

To solve the deficiencies in the prior art, the utility model provides a kind of telescopic jig, including U-shaped fork, snap ring, set Pipe, it is characterised in that：The upper end of above-mentioned U-shaped fork is U-shaped ailhead, and lower end cylindrical outer surface is helicitic texture；Above-mentioned snap ring is Annular circular ring, interior survey lower end is provided with internal thread, and outer upper end diametric(al) opens up two relative tapped through holes, and is rotary with two Set screw；Outside of sleeve is helicitic texture, and is rotary with for fixed nut；Snap ring is connected with sleeve pipe by screw thread, U-shaped fork It is connected with snap ring by two set screws.

The beneficial effects of the utility model are：After using said structure, in wire harness operation process, when needing to carry out collection point During wrapping, tool can be adjusted to low spot.When needing to carry out Ordinary Work, the flexible lofty perch of the tool can be facilitated wire harness Wrapping, is not in situation that wire harness is pulled off, improves production efficiency, and cheap, simple to operate.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

In figure：1 is U-shaped fork, and 2 is snap ring, and 3 is sleeve pipe, and 4 is nut, and 5 is set screw, and 11 is U-shaped ailhead, and 12 is spiral shell Line.

Specific embodiment

In order that the purpose of this utility model and beneficial effect are more clearly understood that, with reference to embodiments, to the utility model It is further described.

As shown in figure 1, the utility model provides a kind of telescopic jig, including U-shaped fork 1, snap ring 2, sleeve pipe 3, it is special Levy and be：The upper end of above-mentioned U-shaped fork 1 is U-shaped ailhead 11, and lower end cylindrical outer surface is screw thread 12；Above-mentioned snap ring 2 is annular circle Ring, interior survey lower end is provided with internal thread, and outer upper end diametric(al) opens up two relative tapped through holes, and is rotary with two positioning spiral shells Silk 5；Outside of sleeve is helicitic texture, and is rotary with for fixed nut 4；Snap ring 2 is connected with sleeve pipe 3 by screw thread, U-shaped fork 1 It is connected with snap ring 2 by two set screws 5.

It should be noted that U-shaped fork 1 is connected by two set screws 5 with snap ring 2, snap ring 2 passes through screw thread with sleeve pipe 3 It is connected, in work process, sleeve pipe is fixed on buck plate by fixing nut 4, and then whole tool is fixed on assembling , it is necessary to when above carrying tool, screw out two set screws 5 on plate, U-shaped fork 1 is reached precalculated position and U-shaped fork 1 can be rotated To complete different working conditions, two set screws 5 are screwed in afterwards so that U-shaped fork 1 is fixed, it is necessary to when shrinking tool, also together The step of before sample repetition, and so on reach tool flexible in arbitrary height, the function of arbitrarily angled rotation, so that it is convenient The wrapping of wire harness, improve production efficiency.

Below general principle of the present utility model and principal character are disclosed with preferred embodiment, but and is not used to limit The utility model processed, all technical schemes obtained using equal replacement or equivalent transformation mode, in guarantor of the present utility model Within the scope of shield.
