According to a preferred embodiment, the lever is formed on the other end thereof is coupled to be slidably movable in the shandong groove, the movement is supported closely to the inner surface of the shandong groove when the load is applied due to the weight of the monitor set It is formed between the piece and the extension extending inclined at a predetermined angle to the moving piece, and consists of a fixed piece that is in close contact with the front surface of the body when a load is applied due to the weight of the monitor set.

According to a preferred embodiment, the fixing means may include a moving piece formed at the other end of the lever and coupled to the sliding groove so as to be slidably moved, the fixed piece being formed to extend inclined at a predetermined angle to the moving piece; The fixing piece is detachably coupled to the front surface of the body, and the liquid crystal image display device is adjusted to a predetermined height so as to restrain the falling of the fixing piece during fixing to prevent the liquid crystal image display device from falling down. Preventive groove is provided.

According to a preferred embodiment, the drop preventing groove is a hook portion which is formed continuously in the vertical direction on the front surface of the body or in the vertical direction on the front surface of the body to prevent the detachment of the fixing piece.

According to a preferred embodiment, a groove is mounted on the top of the body, and a recess for recessing the moving piece is formed to extend the moving stroke of the lever, and the liquid crystal image display device is moved from the body when the position of the liquid crystal image display is moved to the top height. An upper cap is provided to prevent the lever from being detached.

Hereinafter, preferred embodiments of the present invention will be described in accordance with the accompanying drawings, which are intended to be described in detail to be easily carried out by those skilled in the art in order to facilitate the understanding of the present disclosure, For this reason, the technical content of the present application is not limited.

As shown in FIG. 2 and FIG. 5, a liquid crystal plate 2 mounted on the front case 1 and a printed circuit board 4 embedded in the rear case 3 coupled to the front case 1 are formed. The detailed description of the liquid crystal image display device 5, the power cable for applying an electric signal to the liquid crystal image display device 5, the stand 7 to which the signal cable is connected, and the like are omitted.

Therefore, according to the preferred embodiment of the present invention, the body 12 having the T-shaped shankdong groove 11 is mounted on the above-described stand 7, and one end of the liquid crystal image display device 5 is mounted. The other end of the lever 13 fixed to the back is coupled to be slidably movable along the shandong groove 11, the lever 13 is the inner surface of the shandong groove 11 when the load is applied due to the weight of the monitor set It is formed in the rod-shaped moving piece 14 and the extension section 15 extending inclined at a predetermined angle to the moving piece 14 supported in close contact with the front surface of the body 12 when a load is applied due to the weight of the monitor set. It consists of a rod-shaped fixing piece 16 which is closely supported.

The above-mentioned body 12 is provided with a drop preventing recess for adjusting the liquid crystal image display device 5 to a predetermined height to restrain the falling of the fixing piece 16 to prevent the liquid crystal image display device 5 from falling. The fixing piece 16 is formed to be detachably coupled to the front surface of the). Grooves 18 for recessing the aforementioned moving pieces 14 are formed to extend the moving stroke of the lever 13, and the lever from the body 12 when the liquid crystal image display device 5 is moved to the highest height. An upper cap 19 is mounted on the upper end of the body 12 to prevent the departure of the (13).

At this time, as the above-described drop prevention grooves are continuously formed in the front and rear directions of the body 12 in the vertical direction, and the continuous surface in the vertical direction on the front surface of the concave-convex portion 17a or the body 12 to which the fixing piece 16 is fixed. The hook portion 17b may be formed to prevent the fixing piece 16 from being separated.

Hereinafter, a method of using the stand apparatus of the LCD monitor according to the present invention will be described.

As shown in FIG. 3, in the case where the LCD monitor is to be adjusted in height and height so that the LCD monitor can be used in a state suitable for use location or user's preference and physical condition, the above-described liquid crystal image display device ( As the 5) is slightly lifted in the upward direction, the fixing piece 16 of the lever 13 described above is separated from the drop preventing recesses and protrusions 17a formed on the front surface of the body 12. As a result, the locking state of the lever 13 described above is released, and the moving piece 14 of the lever 13 can freely slide along the shanghai groove 11 of the body 12.

In this state, when the above-mentioned liquid crystal image display device 5 is lifted or lowered by a predetermined height and then the liquid crystal image display device 5 is released, the above-mentioned lever 13 is moved by the weight of the monitor set. It is fixed at the predetermined position of 12).

That is, the moving piece 14 of the lever 13 described above is in close contact with the inner surface of the above-described T-shaped shankdong groove 11, and at the same time the lever is extended to be inclined at a predetermined angle with the moving piece 14 The fixing piece 16 formed in the extension section 15 of (13) is supported by being seated in the drop preventing recess 17a formed in the front surface of the body 12.

Therefore, the fixed piece 16 of the lever 13 is separated from the uneven part 17a by the geometrical structure of the moving piece 14 and the fixed piece 16 of the lever 13 mentioned above, and the lever 13 Fall from the body 12 is prevented. This enables the liquid crystal image display device 5 to be fixedly supported at a predetermined position of the desired height of the body 12.

On the other hand, as shown in Figure 4, the lower end of the above-mentioned shanghaidong groove 11 of the body 12 is formed to maintain a predetermined height (h) from the stand 7 (movement of the lever 13) When the piece 14 is lowered to the lowest position, the liquid crystal image display device 5 is formed so as not to come into contact with the bottom surface), and the moving piece 14 of the lever 13 is formed on the shank-dong groove 11 of the body 12. Even when descending to the lowermost position, the above-described liquid crystal image display device 5 is blocked from being in contact with the bottom surface, thereby preventing its breakage when adjusting the vertical height of the liquid crystal image display device 5.

And, as shown in Figure 5, when the moving piece 14 of the above-mentioned lever 13 to the uppermost position of the body 12, the moving piece 14 is the upper portion mounted on the upper body 12 It is recessed in the recess 18 formed in the cap 19 to extend the moving stroke of the lever 13, and at the same time prevents the lever 13 from being separated from the body 12 described above. When the (5) is moved upward along the shanghaidong groove 11 can be prevented from being separated from the body 12.

As described above, according to the preferred embodiment, when adjusting the height, height of the LCD monitor provides convenience to the user by easily adjusting and fixing using the weight of the monitor set itself. When adjusting the height and height of the LCD monitor, it is not necessary to use separate parts, thereby reducing the cost by reducing the number of parts, and greatly improving workability by shortening the labor time of assembling them.
