Abstract

(57) [Summary] [Purpose] To provide a reel that prevents movement due to rolling and that does not hinder the drawing of electric wires and cables. [Structure] An electric wire or cable winding reel in which one of a pair of flanges has a square shape and the other has a circular shape.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvements in reels for winding electric wires and cables.

[0002]

[Problems to be solved by conventional techniques and devices]

 FIG. 2 is a perspective view of an example of a conventional electric wire and cable winding reel. As shown in the drawing, it is composed of a cylindrical winding drum 1 and a pair of circular collars 2.

When storing such reels, if they are left on the floor, they roll and move due to a slight inclination of the floor. Therefore, the reels are stored by using a stopper or loading them on a dedicated pallet. There is also a method to prevent this by placing the reel horizontally, but in this case, the wire or cable wound around the reel during storage will slip off, and the wire or cable will become entangled when it is used next time. Was likely to occur.

As a method for solving such a problem, it is possible to make the flange of the reel square so as to prevent the rolling. However, as a method of pulling out the electric wire and the cable from the reel, as shown in (a) of FIG. Then, insert the shaft into the shaft hole 3 of the reel and rotate the reel to pull out the electric wire and cable A, or fix the reel as shown in (b) of Fig. 3 to fix the electric wire and cable from the side of the collar 2. There is a way to pull out A. However, in the latter case, there is a problem in the square tsuba that electric wires and cables are caught in the corners of the tsuba and smooth drawing cannot be performed.

[0005]

[Means for Solving the Problems]

 The present invention solves the above-mentioned problems and provides a reel that prevents movement due to rolling and does not hinder the drawing of electric wires and cables. The feature of the present invention is that one of a pair of flanges has a square shape and the other has a circular shape. There is something I did.

[0006]

【Example】

 FIG. 1 is a perspective view of a concrete example of a wire and cable winding reel according to the present invention. In the drawings, 1 is a cylindrical winding cylinder, 2a is a square collar, 2b is a circular collar, and 3 is a shaft hole. In the figure, the square brim 2a is shown as an octagon, but it is possible to select a triangle, a quadrangle, a pentagon, a hexagon, etc. depending on the size of the reel and the labor required for processing. The material of the reel is iron, wood, plastic, paper, etc., but any of them can be applied to the present invention.

[0007]

[Action]

 In the reel of the present invention, one of the flanges has a square shape, so that the movement due to rolling can be prevented. Further, since the other flange is circular, it is possible to pull out the electric wire or cable from the side surface of the flange in the same manner as the conventional circular flange.

[0008] When the reel is fixed and the electric wire and the cable are drawn out from the side surface of the flange, as a result of an experiment, it is difficult to smoothly draw out when the ratio of the diameter of the collar / the diameter of the body exceeds 2.5, and in consideration of the winding amount From an economic point of view, 1.3 or higher is required. From this, it is desirable that the above ratio be in the range of 1.3 to 2.5.

[0009]

[Effect of the device]

 As described above, according to the electric wire / cable winding reel of the present invention, it is possible to prevent the movement due to rolling, which not only improves the handleability, but also improves the handling of the electric wire / cable as compared with the conventional reel. It can be handled similarly.
