It is provided with the stand main body 7. As shown in FIG.

However, in the liquid crystal display device described above, the stand main body 7 is also being miniaturized by giving designability in consideration of appearance design according to the miniaturization and thinness of the product.

Due to this, the liquid crystal flat panel display device 5 is tilted toward the user with respect to the stand main body 7 by a hinge assembly not shown or rotated to the left and right by a swivel structure embedded in the stand top member 8. In this case, the ground area according to the miniaturization of the stand body 7 is narrow, and the liquid crystal display device is inverted due to careless handling of the user, and the appearance of the product is damaged, or the liquid crystal flat panel 2 embedded in the liquid crystal display device 5 and The impact is applied to the printed circuit board 4, the function does not work smoothly, there is a problem that the reliability of the product from the user falls.

Accordingly, an object of the present invention is to selectively extend the ground area of the bottom of the stand of the liquid crystal display device to prevent the product from falling when the user tilts or swivels the liquid crystal flat panel display within a predetermined angle range. It is to provide a stand structure of the liquid crystal display device to prevent breakage and damage of the internal components.

The object of the present invention described above is a liquid crystal flat panel display device comprising a front case in which a liquid crystal flat plate is installed and a rear case in which a printed circuit board is embedded, a power cable and a signal cable for applying an electrical signal to the liquid crystal flat panel display. In the stand structure of a liquid crystal display device having a stand connected to the stand, the liquid crystal display device is formed to be retractable on the bottom surface of the stand and selectively extends the ground area of the bottom surface of the stand to tilt the liquid crystal display device within a predetermined angle range. It is achieved by providing a stand structure of the liquid crystal display device, characterized in that it is provided with a fall prevention means that can prevent the fall when swivel.

According to a preferred feature of the present invention, the fall prevention means includes a plurality of receiving grooves formed radially on the bottom surface of the stand and having a semicircular groove on the inner surface thereof, and formed to correspond to the receiving grooves. It extends the ground area of the bottom surface of the stand at the time of withdrawal, and is provided with a sliding member to prevent the flow in the uneven coupling of the groove and the corresponding projection when accommodated in the receiving groove.

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

2 is a bottom perspective view of a stand of the liquid crystal display device according to the present invention, and FIG. 3 is a state diagram of the stand of the liquid crystal display device according to the present invention.

As shown in the figure, a liquid crystal flat panel display device 5 comprising a front case 1 in which a liquid crystal flat plate 2 of a liquid crystal display device is housed, and a rear case 3 in which a printed circuit board 4 is housed; A hinge body (not shown) of the stand main body 7 to which the power cable for applying an electrical signal to the liquid crystal flat panel display device 5 and the terminal 6 of the signal cable are connected, and the liquid crystal flat panel display device 5 are not shown. The structure of the stand top member 8, which is tilted within a predetermined angle range by the structure or rotated to the left and right by the swivel structure not shown, is the same as the conventional one shown in FIG. The description is omitted and the same reference numerals are used.

Therefore, according to a preferred embodiment of the present invention, a plurality of receiving grooves 12 are formed radially on the bottom surface of the above-described stand body 7 so that the semi-circular grooves 10, 11 are opposed to the inner surface. The sliding member 13 is formed to correspond to the receiving groove 12 and extends the bottom ground area of the stand body 7 when withdrawn from the receiving groove 12, but is described above on the side of the sliding member 13. The protrusions 14 and 15 are formed to correspond to the recesses 10 and 11 to prevent the sliding member 13 from flowing from the receiving groove 12.

Meanwhile, the grooves 10 and 11 formed to face the inner side of the storage groove 12 described above and the projections 14 and 15 formed on the sliding member 13 to correspond to the inside of the storage groove 12 are described above. Semicircular protrusions 14 and 15 may be formed on the side surfaces, and grooves 10 and 11 corresponding to the protrusions 14 and 15 may be formed on the side of the sliding member 13 described above.

Referring to the use of the stand structure of the liquid crystal display device according to the present invention configured as described above, as shown in Figure 3, the liquid crystal flat panel display device 5 by the user during the use of the liquid crystal display device stand body 7 Tilt within a predetermined angle range to the user side relative to the user side or rotated left and right by a swivel structure built in the stand top member 8, the several receiving grooves 12 radially formed on the bottom of the stand body 7 The sliding member 13 is pulled out from the bottom surface area of the stand body 7 to be selectively expanded.

That is, as each sliding member 13 accommodated in the receiving groove 12 is pulled outward, the protrusions 14 formed on the side of the sliding member 13 to the outside of the receiving groove 12 corresponding thereto. The projection 15 is separated from the groove 10 of the groove 15 formed inwardly on the side of the sliding member 13 is separated from the groove 11 formed inward of the receiving groove 12, and then of the receiving groove 12 As coupled to the recess 10 formed on the outside, the sliding member 13 can expand the bottom ground area of the stand body 7 in a state in which a part of the sliding member 13 is unevenly coupled to and supported by the receiving groove 12.
