Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a tape guide, and in particular, to a tape guide, in which a long measuring tape used for measuring the striatum is attached to the striatum, which is the object to be measured. Regarding the tape guide used when attaching the tape.

[Technical background of the invention] It has been well known that electric wires are continuously magnetized at regular intervals (for example, 10 m) and that accurate measurements are performed by electrically detecting this magnetization. . When checking the accuracy of such a precision meter, the following work is performed. First, the striatum is wired over a number of rollers over a certain section (usually 50 m) and then strung. A certified steel measuring tape is attached to this strained striatum, and measurements are taken with a standard tension (usually 10 kg) applied to both ends of the measuring tape. And in order to make accurate measurements,
The striatum is held down at regular intervals by tying measuring tape with a string or wrapping vinyl tape around the striatum.

[Problems with the background technology] However, with this method, not only does it take a lot of time and effort to hold the tape with string or vinyl tape, but the elongation of the measuring tape due to the reference tension added to the measuring tape is There was an inconvenience that it was obstructed by string or vinyl tape, resulting in unevenness in the length direction. At this time, if the measuring tape is not held firmly against the filament, the measuring tape will slip off the filament. Therefore, the above-mentioned method is inappropriate as a means for checking the accuracy of a meter that requires accuracy.

[Purpose of the invention] The present invention was made in order to solve the above-mentioned problems, and its purpose is to provide a tape guide that can easily and steadily attach a measuring tape to the striatum.

[Summary of the invention] In other words, the tape guide of the invention includes a substrate and a pair of tape retainers protruding from one surface of the substrate substantially perpendicularly to the substrate and slidably disposed at an appropriate interval. a pair of clamping pieces protruding substantially orthogonally to the board on the other surface of the board and slidably disposed at appropriate intervals, a pair of tape holding pieces and a clamping piece. and a tightening member for removably fixing the to the substrate.

[Embodiments of the invention] Hereinafter, embodiments of the invention will be described based on the drawings. FIGS. 1 and 2 are diagrams showing an embodiment of the present invention. In these figures, a substrate 1 is made of a rectangular metal plate, and has a long hole 2 along its length in the middle part.
is provided. A pair of tape holding pieces 3 and 4 are placed on both sides of the board 1 at appropriate intervals.
and clamping pieces 5, 6 are slidably disposed. The tape holding pieces 3 and 4 and the holding pieces 5 and 6 are each integrally formed by bending a single metal plate so as to protrude substantially perpendicularly to both sides of the substrate 1. Although not shown, through-holes are provided in the lower portions 3a, 4a of the tape holding pieces 3, 4, which are large enough to allow the substrate 1 to pass through. This through hole penetrates the substrate 1 as shown. Numerals 7 and 8 are tightening members such as bolts and nuts, which removably fix the tape holding pieces 3 and 4 and the clamping pieces 5 and 6 to the substrate 1. The tightening members 7, 8 are movable along the elongated hole 2 of the substrate 1, and fix the tape holding pieces 3, 4 and the clamping pieces 5, 6 at arbitrary positions.

A filamentous object 9 such as an electric wire, which is an object to be measured, is held between the two holding pieces 5 and 6, and the tape holding pieces 3,
A measuring tape 10 is placed between the four spaces.

Next, a method of using the tape guide having the above structure will be explained with reference to FIG.

First, a plurality of the above-mentioned tape guides are sandwiched and arranged at appropriate intervals between the wires 9 which are stretched in a conventional manner. Next, a measuring tape 10 is placed on the substrate 1 of each tape guide. After this, measure tape 10
Although not shown, a reference tension is applied to both ends of the tube and a predetermined measurement is performed.

Although the pair of holding pieces 5 and 6 can be adjusted at any interval depending on the outer diameter of the filament, they are usually fixed to the substrate 1 at a predetermined interval. In this way, it can be attached to the filament 9 by simply inserting it. In the present invention, the tape holding part and the holding part are formed separately, and each is attached to the substrate 1 by a fastening member.

In addition, in FIG. 3, numeral 12 is a supply drum, 13
14 is a winding drum, 14 is a cam long, 15 is a tension meter, 16 is a tension applying device, and 17 is a support.

[Effects of the invention] As described above, according to the tape guide of the invention, a pair of tape holding pieces and a pair of holding pieces are slidably disposed on the board, and these are attached to a tightening member. Since the measuring tape is fixed by the wire, the measuring tape can be easily and steadily attached to the filament, and reliable measuring accuracy can be confirmed. Furthermore, since the work of attaching the measuring tape to the striatum is simple, work efficiency can be significantly improved.
