Description
Technical field:
This utility model relates to cable insulation material tension test technical field, more specifically to one stretching work
Dress.
Background technology:
Along with the development of national economy, electric energy obtains utilizing the most widely, therefore for cable as clean energy resource
Demand the most increasing.Cable just can have to produce through strict test, the most just includes cable tensile strain
Experiment.The most in recent years, the Large scale construction of electrical network, the test to cable etc. proposes higher requirement, and reasonable in design
Stretching tool be not only able to simplify cable tensile strain test program, improve test efficiency, it is also possible to increase test safety.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, easy to setup to draw
Stretch the reliable stretching tool of experimental safe.
This utility model solves the scheme of described technical problem: a kind of stretching tool, including support, bolt, upper press ring
With lower pressure ring, described support is the regular hexagon of hollow, and the centre position on described six limits of support is equipped with screwed hole and passes
Screwed hole is provided with bolt, and described internal stent is provided with upper press ring and lower pressure ring, described upper press ring and the lower pressure ring transverse axis with support
Line is symmetrical and is provided with the corresponding bolt position of outer wall of gap, described upper press ring and lower pressure ring between end face is equipped with groove,
Described groove engages with stud base, and described support both sides are equipped with journal stirrup and journal stirrup is provided with installing hole.
Described upper press ring and lower pressure ring are copper product and inwall all carries out annular knurl process.
Inside and outside all arc transition between each limit of described support.
The width of described groove is more than the diameter of bolt.
Prominent effect of the present utility model is: push down cable up and down by upper press ring and lower pressure ring, then with being fixed on
The bolt of the six direction on frame compresses upper press ring and lower pressure ring respectively, it is ensured that cable will not loosen or skid off, and extremely fastens, and
And convenient install and adjust, upper press ring and lower pressure ring are copper product and inwall all carries out annular knurl process so that cable clip obtains tighter,
And copper is soft will not cause damage to cable, inside and outside all arc transition between each limit of support, it is simple to process and attractive in appearance, really
Will not be scratched or cut during security personnel's dress operation, it is ensured that personal safety, be worthy to be popularized, the cable for different model is tested
Time, it is only necessary to change matched upper press ring and lower pressure ring, be greatly improved test efficiency, be worthy to be popularized.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
As it is shown in figure 1, this utility model provides a kind of technical scheme: a kind of stretching tool, including support 1, bolt 3, on
Pressure ring 4 and lower pressure ring 5, described support 1 is the regular hexagon of hollow, and the centre position on described 1 six limits of support is equipped with screw thread
Hole 2 and be provided with bolt 3 through screwed hole 2, internal upper press ring 4 and the lower pressure ring 5 of being provided with of described support 1, described upper press ring 4 and under press
Ring 5 is symmetrical with the transversal line of support 1 and is provided with gap 7 between end face, and described upper press ring 4 is corresponding with the outer wall of lower pressure ring 5
Bolt 3 position is equipped with groove 6, and described groove 6 closes with bolt 3 bottom connection, and described support 1 both sides are equipped with journal stirrup 8 and prop up
Ear 8 is provided with installing hole 9.
Described upper press ring 4 and lower pressure ring 5 all carry out annular knurl process for copper product and inwall.
Inside and outside all arc transition between the described each limit of support 1.
The width of described groove 6 is more than the diameter of bolt 3.
This utility model when in use, pushes down cable, then with being fixed on by upper press ring 4 and lower pressure ring about 5
The bolt 3 of the six direction on support 1 compresses upper press ring 4 and lower pressure ring 5 respectively, it is ensured that cable will not loosen or skid off, very
Fastening, and conveniently install and adjust, upper press ring 4 and lower pressure ring 5 all carry out annular knurl process for copper product and inwall so that cable
Hold tighter, and copper is soft that cable will not cause damage, inside and outside all arc transition between each limit of support 1, it is simple to add
Work and attractive in appearance, it is ensured that will not be scratched or cut when installing operation, it is ensured that personal safety, the cable for different model tries
When testing, it is only necessary to change matched upper press ring 4 and lower pressure ring 5, be greatly improved test efficiency, be worthy to be popularized.
Finally, embodiment of above is merely to illustrate this utility model, and is not limitation of the utility model, relevant skill
The those of ordinary skill in art field, in the case of without departing from spirit and scope of the present utility model, it is also possible to make various change
Changing and modification, the technical scheme of the most all equivalents falls within category of the present utility model, patent protection model of the present utility model
Enclose and should be defined by the claims.
