Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1 to 3, a dumbbell sampling device for wire and cable insulation layers comprises a plurality of dumbbell cutters 1, an upper pressing block 2 and a lower base plate 3, wherein the bottom of each dumbbell cutter 1 is connected with an inclined clamping piece 11, the bottom of each upper pressing block 2 is provided with inclined clamping grooves 21 corresponding to the number of the dumbbell cutters 1, the dumbbell cutters 1 and the upper pressing block 2 are connected by inserting the inclined clamping pieces 11 into the inclined clamping grooves 21, the cross sections of the inclined clamping pieces 11 and the inclined clamping grooves 21 are in a shape like a Chinese character 'tu', the connection is firmer by using the inclined clamping way, the lower base plate 3 is provided with a square through hole 31 corresponding to the dumbbell cutters 1, the length and the width of the square through hole 31 are more than 1.5 times of the length and the width of the dumbbell cutter 1, two groups of adjusting grooves 32 are symmetrically arranged on two sides of the square through hole 31, each group of the adjusting grooves 32 are connected with a pressing strip 34 through bolts and nuts, during the sample, cut out a size and square through hole 31 nearly sample with the scissors earlier, put into square through hole 31 again, through compressing tightly 34 fixed sample both sides, it is smooth to be fixed in square through hole 31 to be convenient for, and cable, optical cable insulation and sheath material for fixed communication that just so can be fine are unlikely to curl and can't level and smooth the sample.

In order to prevent dumbbell cutter 1 from cutting into compression strip 34, the distance between two sets of adjustment grooves 32 is greater than the length of dumbbell cutter 1, so that dumbbell cutter 1 will not cut into compression strip 34 in the later stage no matter how compression strip 34 is adjusted.

In order to facilitate the installation of the device on the punching machine, the upper pressing block 2 is designed to be cylindrical, the center of the upper pressing block 2 is provided with a shaft hole 22, and the lower base plate 3 is provided with an installation hole 35.

The utility model discloses an application principle: install on elevating system's epaxial through shaft hole 22 with last briquetting 2, fix bottom plate 3 on the workstation of punching machine, make dumbbell cutter 1 can both aim at the centre of below square through hole 31 when pushing down through adjusting last briquetting 2, ensure can the later stage can accurate section sample. When using, earlier skin along the axial direction of perpendicular to distribution and communication cable, optical cable through sharp blade and draw materials, the reuse scissors is cut into the size just like the small piece of square through hole 31 size, puts into square through hole 31, will compress tightly strip 34 and press the both ends of small piece through screw bolt and nut 33 and make it level and smooth, treat all put the small piece in the square through hole 31, promote elevating system on the punching machine at last and push away dumbbell cutter 1 and down the pressure and cut the sample article.

The utility model discloses a to be equipped with a plurality of dumbbell cutter's last briquetting and be equipped with the lower plate with the corresponding square through hole of dumbbell cutter installs on the punching machine, the operation of being convenient for is favorable to improving sampling efficiency.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
