Description

Cable Tray {CABLE TRAY}

The present invention relates to a cable tray, and more particularly, to provide a cable tray that is fastened to the first to third semicircular fastening grooves formed in the end of the connecting bar of the entire spiral portion of the bolt.

A "cable tray" is introduced in Korean Patent Application No. 10-2010-86737 (filed Aug. 2, 2010) of the applicant.

The cable tray has a plurality of connecting bars for supporting the cable between the pair of side plates, a locking groove is formed in the side plate so that the side plate and the connecting bar is coupled by a bolt, the bolt in the center of the bottom surface of the locking groove A hole is formed, and a plurality of locking recesses are formed radially on the bottom surface of the locking groove, and a mounting groove is formed at the end of the connection bar to correspond to the locking groove protruding inwardly of the side plate, and inside the mounting portion. A semi-circular bolt receiving portion is formed, and a plurality of ratchet protrusions are radially formed in the head portion of the bolt.

However, in the conventional cable tray as described above, the connecting bar is made of a “┏┓” shaped steel, and one bolt receiving part having a “∩” shape is formed at the end of the connecting bar, thereby providing a coupling force between the bolt and the bolt receiving part. This has a weak disadvantage.

Accordingly, an object of the present invention is to fasten the first to third semicircular fastening grooves formed at the end of the connecting bar by the entire spiral portion of the bolt, thereby increasing the coupling strength of the side plate and the connecting bar, by manufacturing the connecting bar with a square pipe, It is to provide a cable tray with improved safety.

The cable tray according to the present invention for achieving the above object is arranged in a plurality of connection bars for supporting the cable between a pair of side plates, both ends of the connection bar in the cable tray coupled to the side plate, respectively, the bolt It is fastened to the first to third semi-circular fastening groove formed at the end of the connecting bar through the hole formed in the side plate, the connecting bar is formed of a square pipe, a cutting groove is formed at the upper end of the connecting bar, the lower part of the connecting bar Two first and third semicircular fastening grooves convex downward and a second semicircular fastening groove convex upward are formed at the end of the face, and a second semicircular fastening groove is disposed between the first semicircular fastening groove and the third semicircular fastening groove, The stopper is fitted to the end of the connecting bar, the stopper is characterized in that it blocks the cutting groove.

As a result, the cable tray according to the present invention increases the coupling strength between the side plate and the connecting bar, and manufactures the connecting bar with a square pipe, thereby improving safety and preventing water from flowing into the connecting bar by the plug. It has an effect.

1 is a perspective view showing a part of a cable tray according to the present invention.
Figure 2 is a detailed view showing a coupling structure of the side plate and the connecting bar, cut off a portion of the connecting bar.
3 is a cross-sectional view taken along the line AA of Figure 1 showing a coupling structure of the side plate and the connecting bar.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

1 to 3, in the cable tray according to the present invention, a plurality of connection bars 20 for supporting cables are disposed between a pair of side plates 10 and 15, and both ends of the connection bars 20. Are coupled to the side plates 10 and 15, respectively.

At this time, the bolt 40 is fastened to the first to third semicircular fastening grooves 21, 22, 23 formed at the end of the connection bar 20 through the holes 11 formed in the side plate 10, and the connection bar. 20 is formed of a square pipe, the cutting groove 25 is formed at the upper end of the connecting bar 20, the two first and third semicircles that are convex down at the lower end of the connecting bar 20 The fastening grooves 21 and 23 and the convex second semicircle fastening groove 22 are formed, and the second semicircular fastening groove 22 is disposed between the first semicircular fastening groove 21 and the third semicircular fastening groove 23. It is disposed, the stopper 30 is fitted to the end of the connecting bar 20, the stopper 30 to block the cut groove 25.

The cutting groove 25 is cut to form the first to third semicircular fastening grooves 21, 22, and 23 at the end of the connection bar 20, and the stopper 30 is fitted to the connection bar 20. By blocking the cut groove 25, the water is prevented from flowing into the connection bar 20 formed in the form of a square pipe.

The stopper 30 is a plastic injection molded, the "b" shaped leg portion 32 is formed on the lower surface of the upper flat portion 31, the side groove 34 formed by the leg portion 32 is By being fitted to the side of the cutout groove 25, the upper flat portion 31 blocks the cutout groove 25.

In the cable tray according to the present invention configured as described above, the entire spiral portion of the bolt 40 is fastened to the first to third semicircular fastening grooves 21, 22, and 23, and thus the first to third semicircular fastening grooves 21, 22, 23 and the fastening force of the bolt 40 can be maximized, by increasing the coupling strength of the side plate 10 and the connecting bar 20, and by making the connecting bar in a square pipe, safety is improved. In particular, the third semi-circle fastening groove 23 tightly fastens the spiral end of the bolt 40, thereby increasing the tightening strength of the bolt 40.
