Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a cable length measuring device for measuring the length of a cable. For example, unwinding a cable wound around a wooden drum, or unwinding a cable wrapped in a bundle. Cable length measurement suitable for uncoiling cables and measuring their length Regarding ingredients.

0002

[Conventional technology]

Conventionally, for example, a multi-core cable is wound around a wooden drum, and the wound multi-core cable is Unwind the cable or unwind the multi-core cable from a bundle. , to measure its length, use a tape measure or place a scale on your desk. Measure the length by fixing the scale and pressing the unwound multi-core cable against this scale. was being carried out.

0003 However, when measuring length using this method, the unwound cable is It is not possible to measure the length in a straight line, and as a result, the length cannot be measured accurately. There was a problem in that it was not possible to determine

0004

[Problem that the idea aims to solve]

The present invention was developed in view of the above points, and its purpose is to, for example, Unwind a bundled cable, or unwind a bundled multi-core cable. Easily and accurately measure cable length when unraveling and measuring its length. An object of the present invention is to provide a cable length measuring device capable of measuring cable length.

[0005]

[Means to solve the problem]

The above object is achieved by the cable length measuring device according to the present invention. Sunawa In summary, the present invention allows the cable to be measured to be in contact at at least two points. The cable holding part has a substantially V-shaped cross section and has a valley bottom for holding the cable. It is characterized by having a graduation part for displaying the length on the inside of the bull holding part. This is a cable length measuring tool.

[0006]

[Effect]

According to the cable length measuring device of the present invention, cables wound around a drum, etc. Even when uncoiling the cable and measuring its length, the length of the cable can be accurately and accurately measured. can also be measured very easily.

[0007]

【Example】

FIG. 1 is a partial perspective view of an embodiment of the cable length measuring device according to the present invention, and FIG. FIG. 2 is an explanatory diagram when the cable length measuring tool shown in FIG. 1 is used on a flat surface.

[0008] Referring to FIG. 1, a cable length measuring device according to the present invention is shown. The cable length measuring tool 10 is made of a lightweight material such as aluminum. The cable holding portion 11 has a substantially V-shaped cross section. A cable 13 whose length is to be measured is held at the root 12. this cable When the cable 13 is held at the valley bottom 12 of the cable holding part 11, the cable 13 is The cable 13 is connected to the valley bottom 12 at at least two points so as to be held by the bottom 12. Touched and held.

[0009] Furthermore, there are scales on both inner sides of the cable holding part 11 to display the length. A mounting portion 14 is provided. Note that this graduation section 14 is similar to the cable holding section 11. Provided only on one side inside the cable holding part 11, not on both inside sides of the cable holding part 11. The key is to place the cable whose length is to be measured at the bottom 12 of the cable holding part 11. It is sufficient if the length of the cable 13 can be read when the cable 13 is held.

0010 The scale part 14 is directly calibrated on both inner sides of the cable holding part 11. Alternatively, you can attach a graduated tape scale to the cable retainer. It may be configured so that it is attached to both inner sides of 11.

[0011] The operation of the above embodiment will be described below. First, the drum (not shown) ), unwind the cable 13 whose length is to be measured, and Press the bent cable 13 against the valley bottom 12 of the cable holding part 11 and bring it into contact. , this allows the cable 13, which had been wound around the drum and was bent, to be straightened properly. Stretch it into a shape.

0012 The cable 13 thus stretched into a straight line is connected to the cable length measuring tool 10. The scale is read by the graduated parts 14 on both sides of the inside of the holding part 11. Read the length of cable 13. In the above example, the length is measured in this way. Therefore, the length of the cable 13 wound around a drum etc. can be determined accurately and extremely easily. can be measured.

[0013] In the above embodiment, the cable length measuring tool 10 is made of lightweight material such as aluminum. It is lightweight and extremely easy to use.

[0014] Furthermore, when using the cable length measuring device 10 on a flat surface, the cable length measuring device 10 as shown in FIG. A substantially V-shaped cross section of the cable length measuring device 10 is provided on both end sides of the cable length measuring device 10. A mounting table 16 in which a V-shaped groove 15 is formed to receive the cable holding part 11 is provided. (One side of the mounting table is omitted from illustration in FIG. 2), and this mounting table 16 Place the cable length measuring tool 10 on the cable and wind it around a drum etc. in the same manner as described above. The length of the cable 13 can be easily and accurately measured by unwinding the cable 13. can be done. At this time, depending on the length of the cable length measuring tool 10, The number of pieces to be placed may be adjusted as necessary, such as placing the same in the middle of the cable length measuring device 10. It is preferable to select

[0015]

[Effect of the idea]

As explained above, according to the cable length measuring device of the present invention, An abbreviated cross-section having a valley bottom for holding the cable in contact at at least two points. Equipped with a V-shaped cable holding part and displaying the length inside the cable holding part. It constitutes a cable length measuring tool characterized by having a graduation part of Also used when unwinding a cable wound around a ram etc. and measuring its length. , the length of the cable can be measured accurately and extremely easily.
