Keep it. Accordingly, the parts installed on the inner side 11 of the first chassis 10 are fixed while being disposed under the second part 22 of the second chassis 20.

As such, in the chassis for the frame of the present invention, the first chassis 10 and the parts and the second chassis installed therein are operated only by rotating the second chassis 20 while the components are installed in the first chassis 10. 20) can be firmly assembled into one. In particular, since the parts are fixed by the second chassis 20, the mold frame, which was conventionally used for fixing the parts, becomes unnecessary, so that the assembly process of fixing the parts to the mold frame is omitted.

Therefore, in delivering the chassis product for a frame according to the present invention to an LCD module manufacturing company, if the second chassis 20 is coupled to the first chassis 10 with an elastic body 30, the LCD module is manufactured. In a company or the like, the second chassis 20 is opened from the first chassis 10 so as to be in the state of FIG. 5 from the state of FIG. 6, and then the LCD module components are installed in the first chassis 10, and then again as shown in FIG. 6. The assembly process can be completed simply by rotating the second chassis 20 so that the second part 22 of the second chassis 20 covers the upper side of the first chassis 10.

Meanwhile, prior to welding the first chassis, the coupling pieces 40 and 40 'are provided in the coupling grooves 14 and 14' for assembling the first chassis 10 and 10 'adjacent to each other, as illustrated in FIG. Can be inserted to maintain a more robust assembly.

9 is an exploded perspective view showing another embodiment of the present invention corresponding to FIG. 4.

The frame chassis of this embodiment is also composed of the first chassis 100, the second chassis 200 and the elastic body 300, as in the above-described embodiment, there is a difference only in the configuration of the hinge groove and the hinge shaft.

That is, the outer side 120 of the first chassis 100 is bent downward to form a hinge groove 121 at the outermost lower end of the bent, and is composed of a first part 210 and a second part 220 The first part 210 of the second chassis 200 is provided with a hinge shaft 211 coupled to the hinge groove 121.

The first slit groove 121 is provided on the outer side 120 of the first chassis 100, and the first slit groove 121 is provided on the inner side surface of the second part 220 of the second chassis 200. The second slit groove 221 corresponding to the provided, the remaining configuration is the same as the above-described embodiment.

In the above described the present invention based on the preferred embodiment, the present invention is not limited to the above embodiment, various modifications by those skilled in the art within the scope of the technical idea of the present invention This is possible.
