The back side of the circuit board main body 3 is fixedly connected to one side of the positioning block 704. A sliding rod 702 is movably sleeved inside the positioning block 704. One end of the sliding rod 702 is fixedly connected to a top block 707. A double-sided collar 703 is movably sleeved on the outer wall of the sliding rod 702. The other end of the sliding rod 702 is fixedly connected to a support seat 701. One side of the mounting panel 4 is fixedly connected to one side of the support seat 701. When disassembly is required, press the circuit board main body 3. Under the cooperation of the double-sided collar 703 sliding on the sliding rod 702 and the top block 707, the positioning block 704 is separated from the sliding rod 702, and the rapid disassembly of the circuit board main body 3 is completed.

[0021] Furthermore, one side of the positioning block 704 is fixedly connected to a trapezoidal telescopic rod 706. A second return spring 705 is movably sleeved on the columnar outer wall of the trapezoidal telescopic rod 706, which is convenient for the trapezoidal telescopic rod 706 to contract under the elastic action of the second return spring 705 when one end of the trapezoidal telescopic rod 706 is squeezed by the top block 707.

[0022] Further, a protective plate 6 is fixedly connected to the back side of the mounting panel 4. At both ends near one side of the protective plate 6, a buckle assembly 5 is provided. The buckle assembly 5 includes a U-shaped seat 501. On both sides of the inner wall of the U-shaped seat 501, an electric telescopic rod 502 is fixedly connected. At the opposite ends of the two electric telescopic rods 502, a pressing column 503 is fixedly connected. One end of the two pressing columns 503 is movably sleeved with a mounting seat 504, which facilitates turning on the electric telescopic rod 502 under the support of the U-shaped seat 501 and squeezing the pressing column 503 to move within the mounting seat 504.

[0023] Further, an installation groove 505 is formed on one side of the mounting seat 504. A compression spring 506 is fixedly connected to one side of the installation groove 505. A clamping block 508 is movably sleeved on the inner wall of the installation groove 505. A double-headed telescopic rod 507 is fixedly connected to the side of the clamping block 508 close to one side. At both ends of the columnar outer wall of the double-headed telescopic rod 507 close to the two ends, a first return spring 510 is movably sleeved, which facilitates the contraction of both ends of the double-headed telescopic rod 507 under the elastic action of the first return spring 510 when the clamping block 508 drives the double-headed telescopic rod 507 to move and both ends of the double-headed telescopic rod 507 are squeezed by the inner wall of the installation groove 505.

[0024] Further, placing grooves 509 are formed on both sides of the clamping block 508. The two first return springs 510 are movably connected within the two placing grooves 509, which facilitates the movement of the two first return springs 510 into the placing grooves 509 when both ends of the double-headed telescopic rod 507 are compressed.

[0025] Further, a base 2 is fixedly connected to the bottom end of the LCD TV main body 1. The size of the protective plate 6 is adapted to the size of the back side of the LCD TV main body 1.

When it touches the top block 707, it squeezes one end of the trapezoidal telescopic rod 706 to contract under the action of the second return spring 705. Then, when the trapezoidal telescopic rod 706 moves to the bottom end of the top block 707, it bounces and engages under the elastic action of the second return spring 705, which is beneficial to quickly fix the positioning block 704 and the sliding rod 702, thus completing the quick installation of the circuit board main body 3. When disassembly is required, press the circuit board main body 3. Under the cooperation of the double-sided collar 703 sliding on the sliding rod 702 and the top block 707, the positioning block 704 is separated from the sliding rod 702, completing the quick disassembly of the circuit board main body 3. When the circuit board main body 3 needs to be removed from the liquid crystal TV main body 1 by disassembling the protection plate 6 and the installation panel 4, under the support of the U-shaped seat 501, turn on the electric telescopic rod 502 to squeeze the pressing column 503, and then compress both ends of the double-headed telescopic rod 507 in the installation seat 504. It contracts into the placement groove 509 under the elastic action of the first return spring 510. Then, under the elastic action of the compression spring 506, the clamping block 508 bounces up, which is beneficial to separate the clamping block 508 from the installation seat 504, completing the quick disassembly of the protection plate 6 and the installation panel 4.
