Description

[Detailed Description of the Invention] This invention relates to a cable guiding roller device used for cable wiring in wiring ducts, wiring grooves, etc. What is conventionally called a cable guiding roller device is for outdoor use, and as shown in Figure 5, it has a rectangular frame A made of pipe, with each part facing each other made of pipe. Inverted U-shaped side frame openings are provided respectively, rollers A are arranged between these side frame openings, and roller bearing pieces D on both sides of the rollers are supported by the underframe A and the side frame openings. be. This type of device is not suitable for use in wiring ducts where cables are routed in narrow spaces, and it is not suitable for use in wiring ducts installed vertically or diagonally in accordance with the cable wiring direction. It cannot be used because it cannot be done. In view of the above points, this invention is suitable for guiding cables when wiring them in narrow spaces such as wiring ducts, and is suitable for wiring ducts installed vertically or diagonally according to the cable wiring direction. It is an object of the present invention to provide a cable guiding roller device that can effectively cope with the above problems.

Next, this invention will be explained based on the drawings.

A rubber roller 1 whose diameter gradually decreases from both sides to the center is rotatably fitted onto a roller shaft 2. Reference numeral 3 denotes a support plate provided on both sides of the underframe 4, and both sides of the roller shaft 2 fitted into the through hole 3c of the support plate 3 are formed to have a smaller diameter than the shaft part into which the roller 1 is fitted. has been established.
6 and 7 are nuts for fixing the roller shaft 2;
Showing spring washers. and roller shaft 2
Both side portions 2a extend left and right integrally with the roller shaft 2, and form bolt pieces 8 that project from each support plate 3 by an appropriate length in the left and right directions. Numeral 9 is a nut piece formed to a suitable length to correspond to the bolt piece 8, and is screwed into the bolt piece 8. A pressing fixing plate 10 is provided at the end of the nut piece 9, and the central fitting hole 10a of the pressing fixing plate 10 is loosely fitted into a narrow diameter stepped portion 9a formed at the end of the nut piece 9. It is rotatably supported in a nut piece 9.
Reference numeral 11 indicates an escape prevention ring, and reference numeral 12 indicates a lug protruding from the base plate 4. The lug 12 has a mounting hole 13 formed therein. The one shown in Figure 4 is roller 1.
Two of them are installed in series. When wiring a cable in a wiring duct, this device can be inserted into the wiring duct in a direction perpendicular to the wiring duct, and then rotated in the required direction with the nut pieces 9 on both sides of the roller 1, and the cable is pressed and fixed. The plates 10 extend to the left and right, respectively, and are fixed by pressing against both side walls of the wiring duct. In this way, this invented device uses the pressing fixing plates 10 on both sides of the roller 1 that are movable left and right to fix the wiring duct, so it can be fixed even if the wiring duct is oriented in any direction, such as vertically or diagonally. be able to. As described above, this devised device is installed in a wiring duct, and the necessary cables are guided by rollers 1, and its fixing means is a pressing fixing plate 10 on bolt pieces 8 protruding from both sides of the roller 1. Since the nut piece 9 is screwed together, it is not bulky and can be installed in a wiring duct without causing any obstruction to cable wiring. Pressure fixing plate 1
0 can adjust its advancing position by rotating the nut piece 9, so even if the width of the wiring duct is wide or narrow, it can be smoothly accommodated. Ledge piece 1 of base plate 4
The mounting hole 13 formed in 2 is fixed to a suitable platform or building wire running means using other fixing means such as nails, bolts, nuts, etc., and an auxiliary roller, It is intended for use as a laying roller. The configuration in which two rollers 1 are arranged in series as shown in FIG. 4 is useful when the number of cables is large and the wiring positions are different. In this way, this device can guide cables when wiring them in a narrow space such as a wiring duct, and even when the wiring duct is installed vertically or diagonally, it can be easily installed inside the wiring duct. It has various effects, such as being able to guide cables when installed in the area, and being able to be used even if the wiring duct has a wide or narrow width.
