Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings, which are not limitative of one embodiment, but can be variously practiced within the scope of the claims.

2 is an exploded perspective view of a cable tray having a grounding and direction display function according to the present invention. 3 is a cross-sectional view of the connection structure of Fig.

Referring to Figs. 2 and 3, the configuration is composed of the panel 100, the hanger 200, the ground member 300, and the LED module 400.

A pair of the panels 100 may be spaced apart from each other, and a cable may be connected to the hanger 200 between the inside of the panels 100.

Here, the hanger 200 is formed as a profile, and the cable is placed on the upper side.

The panel 100 includes a first panel 120, a second panel 140 disposed at a longitudinal end portion of the first panel 120, and a second panel 140 disposed outside the first panel 120 and the second panel 140 And a bridge panel 160 which is overlapped on the outside.

The first panel 120 and the second panel 140 are the same and are arranged in the longitudinal direction and connected by the bridge panel 160 so that the length of the cable tray can be sufficiently long.

The ground member 300 may be grounded to a metal plate having one side fixed to the first panel 120 and the other side fixed to the second panel 140 and connected to each other. In this embodiment, a square plate is used, but a circular plate may be used.

The grounding member 300 is coupled inside the first panel 120 and the second panel 140 so that the bridge panel 160 can increase the adhesion force to the first panel 120 and the second panel 140 from the outside .

The fixing of the grounding member 300 is performed by a bolt 520 and a nut 540 which are coupled through the bridge panel 160, the first panel 120, the second panel 140 and the grounding member 300 And a fixing member is provided.

That is, one of the bolts 520 is coupled through the bridge panel 160, the first panel 120, and the grounding member 300, and the other one of the bolts 520 is connected with the even number of the bolts 520 Through the bridge panel 160, the second panel 140, and the grounding member 300.

The LED module 400 is for displaying the direction of the emergency evacuation path and includes a first panel 120, a second panel 140, or a bridge panel (not shown) installed in the panel 100, 160, and the direction can be displayed by LED lamp illumination.

Here, the LED module 400 can emit light in the form of an arrow, which is advantageous in that it can be easily identified at night. In the prior art, the reflection plate or the fluorescent material is merely an arrow shape. However, the light is required to have a certain degree of light, but it is often useless in a place where the light is not installed depending on the installation environment of the cable tray.

Therefore, since the LED module 400 is installed, the LED module 400 can self-emit light by an external power source, so that the lighting function can be sufficiently performed to display the emergency escape route direction.

The bridge panel 160 is formed in the first panel 120 and the second panel 140 at a position corresponding to the outer edge of the ground member 300 so that the ground member 300 is fixed by the fixing member And a ground check hole 600 is formed to confirm a state of protrusion due to expansion due to compression.

The grounding member 300 does not protrude toward the grounding confirmation hole 600 before the connection, but when the grounding member 300 is fixed by the fixing member, a pressing force is applied to the grounding member at the time of fixing, It can be confirmed by protruding to the ground check hole 600, so that the fixed state can be easily confirmed.

A central guide hole 620 is formed in the central point of the bridge panel 160 so that the central point of the ground member 300 is also passed therethrough so that the fixing position of the ground member 300 can be determined by the pin .

The fastening state of the grounding member can be easily identified through the grounding confirmation hole 600. In this case, the fastening state of the grounding member can be easily identified through the grounding confirmation hole 600. However, It is possible.

The LED module 400 may be electrically connected to the first panel 120 and the second panel 140, and may display characters, graphics, and graphics in a case where the currents are compared with each other.

The grounding member 300 connects the first panel 120 and the second panel 140 so that when the currents of the first panel 120 and the second panel 140 are different, It is the factor that can determine whether it is not. So, we can display the combined state of LEDs with letters, figures and pictures.

Fig. 4 is another example of an exploded perspective view of a cable tray having a grounding and direction display function according to the present invention, and Fig. 5 is a cross-sectional view of the connection structure of Fig.

4 and 5, the panel 100, the hanger 200, the grounding member 300, the LED module 400, and the like are the same as those of the cable tray having the grounding and direction display function as described above And the grounding member 300 connects the first panel 120 and the second panel 140 and is arranged to directly contact the bridge panel.
