Description

CLAMP FIXING FOR COVER OF CABLE TRAY

The present invention relates to a cable tray cover fixing clamp, and more particularly, to a cable tray cover fixing clamp which can more easily fix and fix the tray cover to the receiving portion by using an elastic force.

Ships and marine structures are equipped with cables of various types and functions, and such cables are installed on a ceiling or a wall surface through a cable tray for securing a traffic passage or for aesthetics inside the ship. In addition, the cable tray is provided with a tray cover for protecting the cable, so that falling objects are prevented from being dropped by the installed cable, or foreign matter such as dust is prevented from accumulating on the cable.

However, while the above-described tray cover has an advantage of cable protection, there is a problem in that it causes additional work such as separation and disassembly of the tray cover at the time of additional cable installation work, which hinders work efficiency. That is, in general, the cable installation operation is performed in the order of mounting and supporting the cable in the cable tray, then mounting the tray cover, and when the installation of the tray cover is required after installation of the tray cover, And a work for disassembling the tray cover is required. For this purpose, the tray cover is usually configured to be fixed and fixed to the base plate using a clamp.

As a representative prior art related to the above-mentioned cable tray, there can be mentioned, for example, Korean Utility Model Laid Open Publication No. 20-2012-0002259 (name: tray cover fixing clamp).

The prior art is a clamp for fixing a tray cover installed on an upper portion of a side rail and includes an upper support body for pressing the tray cover at an upper portion of the side rail and a lower support body extending from the upper support body toward an outer side of the side rail And a lower support body extending from the intermediate connection body so as to surround the lower end of the side rail, wherein the upper support body forms a fixing pin inserted into the hole of the tray cover, And a rotation locking type locking mechanism fixed to a lower end portion of the side rail.

In the process of fastening the clamp of the prior art, the rotary lock type locking mechanism is moved upward relative to the lower support body of the clamp with the fixing pin of the upper support body inserted into the hole of the tray cover, So that the trim formed at the fastening portion is fitted to the outside of the lower end of the side rail to complete the fastening of the clamp.

However, in the case of complicated structures such as ships and marine structures, the installation of additional cables is more frequent after installation of the tray cover. In this case, the installation and dismantling of the tray cover However, as mentioned in the prior art clamp structure, there is a disadvantage that the fastening method is complicated and the tray cover can not be quickly and easily separated and disassembled.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a tray cover and a tray cover which are press- And the tray cover can be more easily fixed and fixed to the base plate by rotating the base plate while the fixing operation is being performed.

According to an aspect of the present invention, there is provided a cable tray cover clamp for detachably fixing a tray cover which is covered on an open top of a receiving portion in which a cable is received, A side plate which is bent downward at both ends of the base plate and which is elastically brought into close contact with the outer surfaces of both sides of the base plate and a base plate which is bent toward the center of the base plate in the inward direction And a grip portion which is bent downward at the tip of the pressure plate, and a grip portion that is bent downward at the tip of the pressure plate.

In the present invention, the tray cover is fixed and unfastened in such a manner that the tray cover is pressed on the upper surface of the tray when the side plate is elastically opened and the outer surface of the tray is wrapped around the tray, It is possible to smoothly perform the additional installation work of the cable by fixing and fixing it.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following detailed description, in order to accomplish the above-mentioned technical problems, two embodiments will be represented in the present invention. And other embodiments which may be suggested in the present specification are replaced by descriptions in the constitution of the present invention.

FIG. 2 is a three-dimensional view showing the state of engagement of the cable tray and the clamp shown in FIG. 1, and FIG. 2 is a cross-sectional view of the cable tray cover fixing clamp according to a preferred embodiment of the present invention, , And Fig. 3 is a sectional view of Fig.

As shown in Figs. 1 to 3, the cable tray 100 of the present invention has a predetermined length and has an upper end opened to have a "U" -shaped cross section, And a tray cover 20 covering the open top of the receiving unit 10 and covering a cable accommodated in the space 12 of the receiving unit 10 .

A clamp 30 is further provided on the outer surface of the receiving unit 10 to fix the tray cover 20 to the upper end of the receiving unit 10.

The clamp 30 according to the present invention elastically wraps the outer surface of the receiving portion 10 and the tray cover 20 and quickly and easily fixes and fixes the tray cover 20 to the top of the receiving portion 10 in a one- .

The clamp 30 includes a base plate 32 made of a metal material so as to be in close contact with the upper surface of the tray cover 20 so as to have a predetermined elastic force and to be bent downward at both ends of the base plate 32, Side plates 34 and 36 elastically adhered to both outer surfaces of the side plates 34 and 36 so as to be elastically in contact with the outer surfaces of the side plates 34 and 36, 10 for pressing the lower ends of the pressing plates 38, 40.

The tabs 42 and 44 are formed by vertically folding down the tips of the pressing plates 38 and 40. The tabs 42 and 44 are formed on the tray cover 20 using a clamp 30. [ The pressing plates 38 and 40 and the side plates 34 and 36 are pressed against the outer side of the receiving portion 10 when the handle portions 42 and 44 are pulled out So that the tray cover 20 can be easily fixed and fixed at the upper end of the receiving unit 10 by unclamping the clamp.

With the clamp 30 constructed as described above, the tray cover 20 can be quickly and easily fixed and fixed to the upper end of the receiving portion 10 in a one-touch manner.

Specifically, when the tray cover 20 is to be fixed to the upper end of the receiving portion 10 by using the clamp 30, the tray cover is covered at the upper end of the receiving portion as shown in FIG. 4 and then the pressing plates 38 and 40 The grips 42 and 44 bent at the tip of the tray cover 20 are pulled out to open the side plates 34 and 36 of the clamp 30 in the outward direction and then the base plate 32 is pulled out of the tray cover 20, The pressing plates 38 and 40 of the clamp 30 press the lower end of the receiving portion 10 upward from below and the upper ends of the side plates The tray cover 20 can be easily fixed to the receiving portion 10 by being elastically brought into close contact with both sides of the receiving portion 10.

When the tray cover 20 is to be separated from the receiving portion 10, the pulling of the tabs 42 and 44 in the above-described manner may cause the pressing plate 38 of the clamp 30 The tray cover 20 is moved downward by pulling the clamp 30 over the tray cover 20 in a state in which the side plates 34 and 36 are extended in the outward direction, ). &Lt; / RTI >

On the other hand, the clamping structure of the clamp 30 having the above-described configuration may be reversed as necessary, preferably in the state in which the base plate 32 is in close contact with the lower end of the receiving portion 10, May be mounted on the upper end of the tray cover 20 so as to be pressed.
