[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0020] The utility model embodiment includes:

[0021] Example 1

[0022] like Figure 1 As shown, the utility model discloses a wire and cable insulating sheet cutting device, comprising a cutting base 10, a cutting pad 20 and a limiting block 30.

[0023] The cutting base 10 is a rectangular stainless steel metal block. The cutting base 10 is arranged horizontally, and its upper surface is smooth and flat.

[0024] The cutting pad 20 is a PVC pad with a flat surface and uniform thickness. The bottom surface of the cutting pad 20 has anti-slip grooves (not shown) to improve its stability when laid on the cutting base 10. The upper surface of the cutting pad 20 has a regular grid composed of vertically arranged horizontal lines 21 and longitudinal lines 22 to facilitate the installation and positioning of the limit seat 30 and as a marking line for the placement of wires and cables. In addition, the setting of the cutting pad 20 can protect the cutting knife or blade. The specifications (length and width) of the cutting pad 20 are the same as those of the upper surface of the cutting base 10.

[0025] The limiting block 30 is a rectangular or cubic stainless steel metal block, which is placed on the cutting pad 20 , specifically, located at one end of the cutting base 10 .

[0026] Along the length direction of the cutting base 10, the limit block 30 is provided with a recessed area 31 from the bottom to the top on one side of the upper surface of the cutting base 10, and the depth of the recessed area 31 is equal to the thickness of the insulating sheet of the wire and cable to be cut. When cutting is required, the end of the wire and cable to be cut is vertically extended into the recessed area 31, and the wall of the recessed area 31 is supported, and then a cutter or a blade is used to perform vertical cutting, which can ensure that the thickness of different positions on the single sheet cut is uniform on the one hand; on the other hand, it can ensure that the thickness of different sheets cut is the same, ensuring the accuracy of the test results.

[0027] The shape of the recessed area is a circular, triangular, rectangular or trapezoidal structure. In the present embodiment, a trapezoidal structure is preferred, and specifically a right-angled trapezoidal structure. The right-angled side of the recessed area of ​​the right-angled trapezoidal structure is located at the bottom of the recessed area, and the length of its long bottom side is less than or equal to the height of the limit block 30. Through the structural design of the recessed area of ​​the right-angled trapezoidal structure, the change in the vertical height between the hypotenuse of the diameter trapezoid and its right-angled side can be utilized, not only can wires and cables of different diameters be used, but also the positions of wires and cables of different diameters can be limited, so that the wires and cables can be stuck in the corresponding position of the recessed area when being cut, to prevent movement during the cutting process, thereby further improving the cutting effect and ensuring the stability of the sheet size.

[0028] The stop block 30 is provided with two through holes in the vertical direction, and the cutting base 10 is provided with a threaded hole matching the through holes on one side facing the upper surface. The stop block 30, the cutting pad 20 and the cutting base 10 are detachably connected by bolts 40 to facilitate replacement of the stop block 30 with recessed areas of different depths to meet the cutting requirements of wire and cable insulating sheets of different thicknesses.

[0029] Example 2

[0030] like Figure 2 As shown, the difference from Example 1 is that the limit block 30 is detachably mounted in the middle of the cutting base 10 , and the middle of the cutting base 10 has a threaded hole matching the through hole of the limit block 30 .

[0031] Along the length direction of the cutting base 10, recessed areas 31 are provided on both sides of the limit block 30 from the bottom upward, and the depths of the recessed areas 31 on the two sides of the limit block 30 are different to meet the cutting requirements of two thicknesses of wire and cable insulating sheets and improve the practicability of the cutting device.

[0032] The utility model discloses a wire and cable insulating sheet cutting device, which improves the convenience of cutting or trimming the wire and cable sheets through the design of a limit block with a recessed area, and the thickness of the wire and cable insulating sheet obtained by cutting is uniform and stable.

[0033] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
