Description

[0001] The present invention relates to a raceway support device,

The present invention relates to a raceway support apparatus, and more particularly, to a support apparatus for fixing a raceway in which electric wires, cables and the like for installing a luminaire are accommodated, The present invention relates to a technical idea capable of largely improving the installation stability of a raceway by preventing the support nut from rotating even when vibration of a building due to vehicle movement or other factors occurs.

A raceway generally refers to a groove in a metal or insulator for receiving and mechanically protecting wires, cables, bus bars, and the like. Such a raceway is widely used for installing a luminaire (lighting device) in a relatively large space such as an indoor parking lot.

In order to mount such a raceway on a ceiling, a metal rod having a screw thread is fixed to the ceiling, and the metal rod has a shape of ∩ shape (for example, aluminum material or plastic material) or ㅁ shape Is fixed, and a method of fastening the raceway to the support device is widely used.

Fig. 1 shows an example of a conventional raceway support apparatus.

1, a through hole is formed in a supporting device (or a hanger) 10 to which a raceway 1 is fastened, and after inserting the computer bar 20 into the through hole, And the support nut 30 is fastened to the bottom surface.

On the other hand, when a moving object such as a vehicle moves within a space such as an indoor parking lot, vibration may be applied to the raceway 1. Or the ceiling of the space where the raceway 1 is installed or the wall surface vibrates and the building itself vibrates in accordance with various external conditions (vehicle movement, strong wind, etc.) of the space in which the space exists, Vibration may be transmitted to the rods 20.

In this case, even if the two support nuts 300 are tightened tightly, there is a high possibility that the tightening is loosened if the vibration continues, and if the installation height of a part of the raceway 1 is changed or is severe, There is a risk that the fixture is disassembled and the raceway 1 may fall on the ground.

Also, since the two support nuts 300 are strongly tightened, there is a great inconvenience in not only the installation itself but also the height adjustment of each supporting device 10 appropriately.

A technical idea for solving such difficulties is disclosed in Korean Patent (Registration No. 10-1031822, "Wire Duct Clamp ", hereinafter referred to as prior art).

The above-mentioned prior art has a configuration in which a body of a clamp (supporting device) is fitted to a hanger rod (computer bar) without separately forming a support nut and the rotation bracket is fixed by rotating and then the wedge is inserted and fixed in the hole.

However, in such a configuration of the related art, there is a problem that as the rotation of the rotation bracket is repeated, the rotation part of the rotation bracket is worn and the rotation itself is loosened. Particularly, when the material of the clamp (support device) is plastic, such a problem can be further increased.

When the fixing is loosened, there is a high possibility that the rotating bracket, which has been rotated in the fixing direction, is rotated in the opposite direction due to the vibration or the like. To prevent this, the conventional technique uses a method of inserting the wedge into the hole.

However, there is a great inconvenience in relatively inserting / releasing the wedge having a relatively small size during the work such as installation work or maintenance work of the raceway 1, and there is a great risk of losing the wedge itself.

Therefore, by using only one support nut, it is possible to securely fix the raceway support device to the computer bar, thereby improving the convenience of the operation, and effectively preventing the rotation of the support nut due to various vibrations, It is necessary to make a technical idea that can greatly increase it.

FIG. 2 is a front view of a raceway support apparatus according to an embodiment of the present invention. FIG. 3 is a plan view and a bottom view of a raceway support apparatus according to an embodiment of the present invention. 6 is a perspective view of a raceway support apparatus.

Referring to the drawings, a raceway support apparatus 1 according to an embodiment of the present invention includes a body 100, a metal rod 200 having threads formed on an outer circumferential surface thereof, and a support nut 200 fastened to the metal rod 200. [ (300).

The body portion 100 may include a top surface portion 110 and a side surface portion 120.

As shown in FIG. 3A, the top surface 110 may be formed to penetrate through the top surface in the vertical direction to allow the computer bar 200 to be inserted therethrough. As shown in FIG. 2, the side surfaces 120 may be extended downward from both sides of the top surface 110.

Although the body 100 is divided into the upper part 110 and the side part 120 for convenience of description, the body part 100 may be integrally formed to have a shape of ∩ Of course. Also, according to an embodiment, the top surface 110 may be formed in a planar shape or a curved surface having a predetermined curvature. Further, the corner where the upper surface portion 110 and the side surface portion 120 meet may have various shapes as required, such as an angular shape or a round shape.

Although the body 100 is formed of a plastic material for the sake of convenience in manufacturing, the present invention is not limited thereto. If the body 100 has the same shape and effect as the body 100, ) Does not have any particular limitation.

As a result, the body 100 may be formed to have an ∩ -shaped cross section having a front, a rear, and a bottom as a whole, and the raceway may be supported by fitting a raceway into an empty lower portion.

For this, the side part 120 may have a fastening part 130 for fastening the raceway to the lower end thereof. As shown in FIG. 2, the fastening part 130 may protrude in the form of a hook or protrusion inward of the body part 100, and may be fastened to a protrusion or a groove for fastening formed on a side surface of the raceway. have.

The computer bar 200 is inserted into the through hole 150 and is fixed to a ceiling where the raceway is to be installed to support the raceway support apparatus 1 through the support nut 300.

At this time, a screw thread is formed on the outer circumferential surface of the computation rod 200 to easily adjust the installation height of the raceway support apparatus 1 according to the rotation of the fastening support nut, Can be prevented from falling.

Meanwhile, the through-hole 150 may be formed to have a larger diameter than the diameter of the computer rod 200 for smooth insertion of the computer rod 200. However, when the diameter of the through-hole 150 is larger than necessary, there is much room for the computer rod 200 to vibrate in the through-hole 150, so that the installation stability of the raceway may be greatly reduced. Accordingly, it is preferable that the through-hole 150 is formed to have a larger diameter in a range of about 1 mm or less than the diameter of the computer rod 200.

The support nut 300 may have a diameter larger than the diameter of the through-hole 150 by a predetermined length. For example, as shown in the figure, the support nut 300 is fastened from the bottom surface direction of the computer bar 200 and the raceway support apparatus 1 inserted in the through hole 150, 300 can be supported by the support nut 300 of the raceway support apparatus 1 by having a larger diameter than the through-hole 150.

Unlike the conventional raceway support apparatus 10 which is fixed by using at least two support nuts 30 as described in FIG. 1, according to the technical idea of the present invention, by using one support nut 300, Thereby supporting and fixing the wafer support apparatus 1. In this case, the rotation of the raceway support apparatus 1 itself may be prevented by the raceway fastened to the raceway support apparatus 1, but the support nut 300 may be installed in the space where the raceway is installed The height of the installed raceway may be changed due to the vibration caused by the movement of the vehicle or the vibration of the building itself due to the external situation, and in the worst case, there is a danger that the installed raceway may be dismantled have.

In order to prevent such a risk, the raceway support apparatus 1 according to the technical idea of the present invention has the through hole 150 on the bottom surface of the upper surface portion 110 as shown in FIG. 3B and FIG. 4, A groove 160 may be formed to allow a part of the support nut 300 to be inserted.

That is, the groove 160 does not penetrate the entirety of the upper surface portion 110 like the through hole 150, but is formed only at a predetermined depth from the bottom surface of the upper surface portion 110 as shown in FIG. 4 So that the support nut 300 can be engaged.

At this time, the groove 160 is formed to correspond to the shape of the support nut 300, thereby preventing rotation of the support nut 300 inserted into the groove. Although the grooves 160 are formed in a hexagonal shape, the support nut 300 has a hexagonal shape, and the scope of the present invention is not limited thereto. For example, the support nut 300 may be formed in various shapes such as a quadrangular shape and an octagonal shape. The groove 160 may have a shape corresponding to the shape of the support nut 300 according to the shape of the support nut 300 As shown in FIG.

As a result, when the angular support nut 300 is inserted into the groove 160, the support nut 300 is not pulled out from the groove 160 itself, unless the support nut 300 has a rounded shape, The rotation of the support nut 300 fastened to the computer rod 200 can be physically cut off.

The grooves 160 may be formed such that the entirety of the support nuts 300 can be inserted into the grooves 160. However, the grooves 160 may be formed at a depth where only the upper portion of the support nut 300 can be inserted. This is because it is difficult for the support nut 300, which starts to be inserted into the groove 160, to be inserted deeply into the groove 160 because the depth of the groove 160 can not be further rotated, This is because the height of the support device 1 may be rather uncomfortable.

As a result, according to the technical idea of the present invention, as shown in FIG. 2, the computer 200 is inserted into the through hole 150, and the support nut 300 is fastened from the lower end of the computer 200 So that the body 100 can be fixed at a predetermined height. When the raceway is fastened to the body 100, the body 100 receives a force in the direction of the ground due to the weight of the raceway itself, and the bottom surface 110 of the body 100 The support nut 300 supports the body 100, so that the raceway can be easily installed. Particularly, even if the support nut 300 is vibrated through the thread of the computer rod 200 and the groove 160, the support nut 300 can be fixed firmly without rotating, The raceway can be stably supported and fixed.

As described above, according to the embodiment of the present invention, the through hole 150 is formed to have a diameter larger than a diameter of the computer rod 200 by a predetermined length (for example, 1 mm) The supporting device 1 itself can be swung back and forth along the gap between the through hole 150 and the computer bar 200. This is because the thinner the thickness of the upper surface portion 110, There is a possibility that it can be a great threat. For example, the through hole 150 formed in the upper surface portion 110 of the plastic may be widened due to the friction with the computer rod 200, or the upper surface portion 110 or the body portion 100, It may rupture itself. Alternatively, when the insertion angle of the computer bar 200 is greatly distorted due to the shaking, the support nut 300 inserted into the groove 160

Therefore, according to the technical idea of the present invention, as shown in FIG. 2, a penetration part 140 formed to have a predetermined height in the shape of concentrating the through hole 150 is formed on the upper surface of the upper surface part 110 . ≪ / RTI >

In this case, the through-hole 150 may be formed to penetrate the penetration portion 140 and the upper surface portion 110. After the computer rod 200 is inserted, the body portion 100, It is possible to cover a larger area of the computer rod 200 through the penetration part 140 even if the rods 200 are slightly shaken so that the risk of breakage of the body part 100 as well as the shaking itself can be prevented And the stability can be greatly improved.

As described above, when the body 100 is made of a plastic material, the body 100 may be damaged according to the weight of the raceway. Therefore, according to the embodiment of the present invention, at least a part of the side surface of the penetration part 140 having a certain height in the top surface direction of the top surface part 110 and the side surface of the top surface part 110 and the side surface part 120 A reinforcing portion 170 having a predetermined thickness and a predetermined height may be formed. The reinforcing portion 170 may have a greater resistance to bending, twisting, etc., than the body portion 100, and as a result, it may have the effect of improving the stability of the raceway supporting device 1.

Hereinafter, an actual use process of the raceway support apparatus 1 according to an embodiment of the present invention will be briefly described with reference to FIG.

5 shows an operation example of a raceway support apparatus according to an embodiment of the present invention.

5A, a raceway 1 is supported by a lower portion of a raceway support apparatus 1 according to an embodiment of the present invention, that is, a fastening portion 130 formed on both side portions 120 of the body portion 100, Can be fastened.

The metal rod 200 is inserted into the through hole 150 formed in the upper surface portion 110 and the support nut 300 can be fastened from the lower end of the metal rod 200. The support nut 300 may be fastened by a user according to a height required to install the raceway 1 on the computer bar 200.

5B, the support nut 300 may be inserted into the groove 160 formed in the bottom surface of the upper surface portion 110. As shown in FIG. As described above, the groove 160 has a shape corresponding to the support nut 300, so that the support nut 300 inserted into the groove 160 can no longer be rotated.

Particularly, when the raceway 1 is fastened to the raceway support apparatus 1, the weight 100 of the raceway 1 causes the support nut 300 to move in the direction of the ground The rotation of the support nut 300 is physically impossible unless the user releases the fastening of the raceway 1 or the user partially lifts the body 100. Accordingly, The installation height of the raceway 1 can be stably fixed.
