It can be used by changing depending on the separation distance. By being interchangeable in this way, the gap block 130 according to an embodiment of the present invention can be used between the liquid crystal panel 200 and the case 300 having a plurality of shapes.

And the second block 132 is formed vertically in the direction of the floor and is coupled to the control unit 140. At this time, the second block 132 moves forward and backward through the control unit 140, which will be described later, and the first block 131 installed together is positioned between the liquid crystal panel 200 and the case 300. It can be placed in the correct location.

The block 131 includes a second coupling hole (131-1) formed at a position corresponding to the first coupling hole (131-1a). At this time, the first block 131 may be attached using a fixing member (not shown) penetrating the first coupling hole 133-1a and the second coupling hole 131-1. In this way, as the first coupling hole (133-1a) and the second coupling hole (131-1) are coupled through a fixing member (not shown), replacement can be smoothly provided in a detachable form.

And the rotating portion 133-2 includes a rear projection 133-2a and a rotating hole 133-2b. At this time, the rear protrusion (133-2a) is provided at the rear of the coupling portion (133-1) and protrudes rearward, and the pivot hole (133-2b) is formed to penetrate the center of the rear protrusion (133-2a). .

That is, by rotating around the shaft hole 132-2, it can be accurately positioned between the liquid crystal panel 200 and the case 300 with minimal user intervention.

Next, the support module 134 is formed to be spaced apart from the rear of the second block 132 and is formed to support the second block 132. At this time, the support module 134 supports the second block 132, thereby preventing the second block 132 from moving in another direction. In addition, in order to effectively support the second block 132, it is formed above the center of the second block 132 to prevent rearward separation of the second block 132.

Next, the vertical portion 135 is formed to have a constant inclination toward the bottom surface of the opposite side of the first block 131 to which the movable coupling member 133 is coupled, and from the end of the inclination. It is formed to go vertically down to the floor. One side of this vertical portion 135 may be formed to be longer in the floor direction than the other side. As the vertical portion 135 is formed in this way, it can be formed to correspond to the shape of the liquid crystal panel 200 and the case 300.

By forming the gap block 130 in this way, the liquid crystal panel 200 and the case 300 can be positioned at an exact spaced apart position, and minute errors between the liquid crystal panel 200 and the case 300 can be reduced.

Next, the adjustment unit 140 includes a support part 141, a moving rail 142, a moving part 143, and a stopping part 134. First, the adjustment unit 140 is coupled to the lower side of the gap block 130 and is used to move the first block 131 in the horizontal direction.

The support portion 141 is formed and coupled to the lower side of the gap block 130. At this time, the lower side of the gap block 130 refers to the lower side of the second block 132. That is, the upper side of the support portion 141 is coupled to the lower side of the second block 132. This support portion 141 is formed to be larger than the area of the lower side of the second block 132 to provide more solid support for the gap block 130.

Next, the moving rail 142 is formed on the lower side of the support part 141 and provides movement of the support part 141. At this time, the moving rail 142 may be formed on both sides of the lower side of the support part 141, and the support part 141 may include a rail (not shown) corresponding to the moving rail 142. That is, the support portion 141 is coupled to the moving rail 142 through a rail (not shown), and can move forward or backward in the moving direction of the moving rail 142 while coupled.

And the moving part 143 is formed on the side of the support part 141, and moves the moving rail 142 to move the support part 141. At this time, the moving part 143 can move the support part 141 using hydraulic pressure, because fine movement can be provided when using hydraulic pressure. By providing fine movement using the moving part 143, the gap block 130 can be positioned at the correct position between the liquid crystal panel 200 and the case 300, and the movement of the gap block 130 Accordingly, the force applied to the liquid crystal panel 200 can be reduced.

Next, the stopping part 144 is formed on the opposite side of the moving part 143 to stop the movement of the supporting part 141. That is, the stopping part 144 is used to prevent the gap block 130 from moving to an excessive position through the moving part 143. In this way, excessive movement of the gap block 130 can be controlled through the stopping part 144 and positioned at an accurate insertion position between the liquid crystal panel 200 and the case 300.

Next, the liquid crystal panel guide 150 is provided on the bottom surface and supports the lower side of the liquid crystal panel 200. At this time, the liquid crystal panel guide 150 may be formed in plural pieces, and the liquid crystal panel guide 150 may be formed through the hole formed in the support module 110 described above. That is, the liquid crystal panel guide 150 is formed together with the support module 110, and a plurality of liquid crystal panel guides 150 may be formed inside the support module 110. This liquid crystal panel guide 150 is directly engaged with the lower side of the liquid crystal panel to support and guide the liquid crystal panel. The liquid crystal panel guide 150 may be formed of a shock-absorbing material such as sponge or rubber, especially as described later. As the pressing module 170 is pressed, it may be formed of a material to distribute the force of the liquid crystal panel 200 and the liquid crystal panel guide 150. As the liquid crystal panel guide 150 is formed in this way, the defect rate of the liquid crystal panel 200 can be reduced.

Next, the lifting module 160 is provided below the liquid crystal panel guide 150 and moves up and down according to the external force applied to the liquid crystal panel 200. That is, the lifting module 160 moves up and down according to the pressure applied to the liquid crystal panel guide 150. When the pressure applied to the liquid crystal panel guide 150 is high, it descends toward the floor at a relatively high speed, and the liquid crystal panel guide 150 moves up and down. When there is no pressure applied to the panel guide 150, it rises to its original position.

And the lifting module 160 is fixed to the lower side of the floor and includes a fixing member 161 including the lifting hole 161-1, a lifting member 162 that is inserted into the lifting hole 161-1 and moves up and down, and a lifting member. It includes an attachment member 160 to which the lower side of the liquid crystal panel guide 150 is attached to the upper side of (162).

First, the lower side of the fixing member 161 is fixed to the floor and is formed perpendicular to the direction of the liquid crystal panel 200. Additionally, the fixing member 161 includes a lifting hole 161-1 formed from the upper side to the bottom side, and the lifting member 162 is coupled to the lifting hole 161-1. The lifting member 162 moves up or down through hydraulic pressure while being coupled to the lifting hole 161-1. At this time, the lifting member 162 is raised and lowered using hydraulic pressure when the pressure module 170, which will be described later, applies pressure to the liquid crystal panel 200, using a different lowering method to reduce the descending speed in proportion to the size of the pressure. Use more hydraulic pressure. By using hydraulic pressure in this way, the pressure applied to the liquid crystal panel 200 and the pressure applied through the lifting module 160 are set to 0, thereby preventing damage to the liquid crystal panel 200. In addition, in the case of the liquid crystal panel 200 having a curvature, it is vulnerable to external pressure, so the lifting member 162 is used to generate hydraulic pressure.

And the lower part of the attachment member 163 is attached to the upper side of the lifting member 162, and the upper part of the attachment member 163 is attached to the lower side of the liquid crystal panel guide 150. That is, the attachment member 163 is used to connect the liquid crystal panel guide 150 and the lifting module 160. At this time, the attachment member 163 may have adhesive force, and the adhesive force of the lower and upper sides may be different depending on the user's selection. That is, a material with high adhesive strength can be used for the lower part, and a material with lower adhesive strength than the material formed on the lower part can be used for the upper part. Accordingly, the above-described liquid crystal panel guide 150 can be easily replaced.

Next, the pressing module 170 includes a moving member 171, a horizontal plate 172, and a pressing member 173. First, the moving member 171 is coupled to a pair of vertical rails spaced apart on both sides of the support module 110 to raise and lower the horizontal plate 172 and the pressing member 173, which will be described later. That is, the moving member 171 can pressurize the liquid crystal panel 200 and the case 300 by lifting the horizontal plate 172 and the pressing member 173. Next, both sides of the horizontal plate 172 are coupled to one end of the moving member 171 formed in the form of a rail on both sides. That is, the horizontal plate 172 is formed on the moving member 171 and can move through the moving member 171. Next, the pressing member 173 is provided to protrude from the horizontal plate 172 toward the support module 110 or toward the floor. Here, the pressing member 173 includes an elastic part 173-1 and a pressing part 173-2. First, as shown in FIG. 8, one side of the elastic portion 173-1 is coupled to the horizontal plate 172, is formed perpendicular to the bottom surface, and includes a spring on the outside. At this time, the elastic portion 173-1 can reduce the force applied to the liquid crystal panel 200 to a minimum when the liquid crystal panel 200 is pressed through a spring formed on the outer side, thereby preventing the liquid crystal panel 200 from cracking or breaking. Cracks can be prevented. In addition, the pressing portion 173-2 is formed in the same shape as the liquid crystal panel 200, and is detachable so that it can be changed to a shape corresponding to the liquid crystal panel 200.

The present invention described above with reference to the accompanying drawings is capable of various modifications and changes by those skilled in the art, and such modifications and changes not limited by the claims should be construed as being included in the scope of rights of the present invention.
