[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1 to 3, the present utility model provides a technical solution: The main board mounting assembly of the liquid crystal TV includes a housing 1, a bottom plate 2, a circuit board 5, and a fixing assembly 6. The bottom plate 2 is arranged inside the housing 1, the bottom plate 2 is located below the housing 1, the circuit board 5 is arranged on the upper end of the bottom plate 2, the circuit board 5 is located above the bottom plate, and a fixing assembly 6 for limiting the circuit board 5 is arranged on the bottom plate 2.

[0030] Please refer to Figure 4 and 5 , the fixing assembly 6 includes a plurality of T-shaped grooves 61 opened inside the bottom plate 2, a plurality of screw holes 62 evenly distributed are opened inside the plurality of T-shaped grooves 61, a slider 63 is slidably connected inside the plurality of T-shaped grooves 61, and the outer contour of the slider 63 is adapted to the inner contour of the T-shaped groove 61 to facilitate adjusting the position of the slider 63 relative to the plurality of T-shaped grooves 61.

[0031] A fixing bolt 64 is rotatably connected inside the slider 63, so that the slider 63 can be screwed to the screw hole 62 through the bolt 64, thereby facilitating the position limitation of the slider 63 relative to the T-shaped groove 61 through the bolt 64. A moving frame 65 is fixedly connected to the upper end of the slider 63 to facilitate the movement of the moving frame 65 along with the movement of the slider 63. A screw rod 66 is threadedly connected inside the moving frame 65. The upper end of the screw rod 66 is fixedly connected with a knob 67, and the lower end of the screw rod 66 is rotatably connected with a pressing plate 68 to facilitate the user to rotate the knob 67 and drive the screw rod 66 to rotate, thereby facilitating the lifting of the pressing plate 68 along with the rotation of the screw rod 66.

[0032] Please refer to Figure 5 , two symmetrically distributed guide rods 69 are fixedly connected to the upper end of the pressing plate 68, and both guide rods 69 are slidably connected to the moving frame 65 to facilitate the lifting of the pressing plate 68 relative to the moving frame 65 under the guiding action of the two guide rods 69, thereby facilitating the improvement of the movement smoothness of the pressing plate 68 relative to the moving frame 65.

[0033] Exemplarily, the moving frame 65 may be a base or a frame that allows the pressing plate 68 to move up and down or slide. Through the sliding connection between the guide rods 69 and the moving frame 65, the pressing plate 68 can achieve smooth up and down movement under the guidance of the guide rods 69. Through this design, the guide rods 69 can ensure that the pressing plate 68 remains balanced and stable during up and down movement, preventing it from tilting or swaying. This symmetric distribution and sliding connection configuration can also provide better positioning and guiding performance, enabling the pressing plate 68 to move accurately and smoothly during operation.

[0034] Please refer to Figure 5 , the slider 63 is a T-shaped block, and a through hole is opened inside the slider 63 to facilitate the adaptation of the outer contour of the slider 63 to the inner contour of the T-shaped groove 61, and the through hole is used for the bolt 64 to pass through.

[0035] Exemplarily, the T-shaped block is usually a part with a T-shaped cross-section. One side of it has a T-shaped protrusion, while the other side is flat. The T-shaped groove 61 is a groove adapted to the T-shaped block and can be used to accommodate the T-shaped block. The cross-sectional shape of the T-shaped groove 61 matches the shape of the protrusion of the T-shaped block to ensure that the two can be fully engaged. By inserting the T-shaped block into the T-shaped groove 61, they can be closely fitted to provide a stable connection. This pairing structure has good tensile resistance and torsional stiffness, enabling the connected objects to resist the action of external forces and not easily loosen or misalign.

[0036] Please refer to Figure 5 , the through hole is rotatably connected to the fixing bolt 64, and the fixing bolt 64 is threadedly connected to the screw hole 62.

[0037] Exemplarily, the fixing bolt 64 cooperates with the screw hole 62 to fix the slider 63 so that the slider 63 is in a fixed state relative to the bottom plate 2.

[0038] Please refer to Figure 1 , the inner part of the housing 1 is provided with a top plate 3.

[0039] Exemplarily, the top plate 3 of the liquid crystal TV is usually used to seal the housing 1 to protect the internal circuit and components from the external environment and provide structural support and stability. This sealing is usually achieved by a rubber pad or sealant between the top plate 3 and the housing 1. During the assembly process, the top plate 3 will be closely attached to the edge of the TV housing 1, and appropriate sealing materials will be used for bonding or encapsulation to prevent dust, moisture and other sundries from entering the TV interior. The sealed top plate 3 helps to maintain the normal operation of the TV and provides an additional protective layer to protect the circuit from external physical and environmental damage. In addition, the sealing also helps to prevent sound from leaking out from the back of the TV and provides better audio effects.

[0040] Please refer to Figure 1 and 2 , two wire passing holes 4 are symmetrically arranged on the side wall of the housing 1.

[0041] Exemplarily, the wire passing holes 4 are arranged on the side wall of the housing 1 to facilitate the connection wires to pass through the housing 1 through the wire passing holes 4.

[0042] Please refer to Figure 6 , a limiting component 7 for limiting the connection wires of the circuit board 5 is arranged on the bottom plate 2. The limiting component 7 includes a plurality of fixing plates 71 fixedly installed at the upper end of the bottom plate 2. Fixing rods 72 are fixedly connected to the side walls of the plurality of fixing plates 71. A spring 73 is sleeved on the outer side of the fixing rods 72. One end of the fixing rods 72 is fixedly connected to a limiting disc 74. A limiting frame 75 is slidably connected to the outer side of the fixing rods 72.

[0043] Exemplarily, when the connecting wire slides into the upper end of the limit frame 75, the limit frame 75 moves backward and the spring 73 is compressed. When the connecting wire slides into the lower end of the limit frame 75, the limit frame 75 moves toward the limit plate 8 under the elastic force of the spring 73, and the limit frame 75 cooperates with the limit plate 8 to limit the connecting wire.

[0044] See also Figure 6 The limiting frame 75 abuts against one side of the limiting plate 74 , and the limiting frame 75 is slidably connected to the bottom plate 2 .

[0045] Exemplarily, the limiting plate 74 limits the limiting frame 75 , the limiting frame 75 is slidably connected to the upper end of the bottom plate 2 , and the bottom plate 2 limits the limiting frame 75 .

[0046] See also Figure 3 and 6 The upper end of the bottom plate 2 is fixedly connected with a plurality of limit plates 8 which are respectively used in conjunction with a plurality of limit frames 75 .

[0047] Exemplarily, the limiting plate 8 and the limiting frame 75 are used together, and the limiting plate 8 and the limiting frame 75 form a sealed space to facilitate the limiting of the connecting line.

[0048] See also Figure 6 The limiting frame 75 is an L-shaped frame, and the limiting frame 75 is provided with a horizontal plate, and the horizontal plate is provided with a chamfering treatment.

[0049] Exemplarily, the limiting frame 75 is an L-shaped frame, and the horizontal plate of the L-shaped frame facilitates the limiting frame 75 to fix the connecting wire, and the upper end of the horizontal plate is chamfered to facilitate the connecting wire to be inserted into the interior of the limiting frame 75.

[0050] Working principle: When the utility model is used, the cross-sectional shape of the T-slot 61 matches the convex shape of the T-block to ensure that the two can fully bite. By inserting the T-block into the T-slot 61, they can fit tightly to provide a stable connection. The slider 63 drives the movable frame 65 to move. The fixing bolt 64 cooperates with the screw holes 62 at different positions to limit the slider 63 at different positions. The movable frame 65 limits the side of the circuit board 5. The knob 67 is rotated to cause a threaded movement between the screw rod 66 and the movable frame 65 to control the screw rod 66 to rise and fall. The screw rod 66 drives the pressure plate 68 to rise and fall. The pressure plate 68 limits the upper end of the circuit board 5. When the pressure plate 68 rises and falls, the guide rod 69 plays a guiding role. The movable frame 65 is provided with multiple ones, which can limit the circuit boards 5 of different widths.

[0051] When the connecting wire slides into the upper end of the limiting frame 75, the limiting frame 75 moves backward and the spring 73 is compressed. When the connecting wire slides into the lower end of the limiting frame 75, the limiting frame 75 moves toward the limiting plate 8 under the elastic force of the spring 73, and the limiting frame 75 cooperates with the limiting plate 8 to limit the connecting wire.
