[0004] As an improvement, the mounting hole is a rectangular hole with a length of d1 and a width of d2. The turntable block is a rectangular structure, wherein the rectangular length of the turntable block is less than d1 and the width is less than d2. <d2。
[0005] As an improvement, the rear shell buckle also includes a gripper seat, a stopper, and an extension platform; the gripper seat is provided with two, which are symmetrically installed on both sides of a pair of hook sides away from the center point and close to the extension platform; the extension platform is located at the two ends of the bottom plate; the stopper is provided with two, which are independently installed at the bottom of the two extension platforms.
[0006] As an improvement, the extension platform is an elastic structure, and when the two gripper seats are relatively close to or loosened, the extension platform can be bent upward or downward.
[0007] As an improvement, the stopper and the mounting hole are installed in a limited snap-fit manner, wherein the short side direction is limited and the long side direction is tightly against the edges of the two openings of the back plate.
[0008] As an improvement, it further comprises two reinforcing plates, each of which is independently used to connect each side surface of the hook and the top surface of the base plate.
[0009] Beneficial effects: Compared with the existing conventional structure, the structure proposed by the present utility model is characterized in that some small buckles cooperating with the rear case are assembled inside the machine, replacing the current method of fixing these small buckles to the metal backplane with screws. The screw fixing method of the small buckles is optimized into a screwless hook fixing method, truly realizing the screwless of the rear case. This structure can further reduce production costs and improve production efficiency. Description of the Drawings

[0022] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with embodiments. The following embodiments are used to illustrate the present utility model, but not to limit the scope of the present utility model.
[0023] See Figures 3-11 As shown, a screw-free fixing structure for the back shell buckle of a liquid crystal TV is provided, including mounting holes 6 and back shell buckles 7; a plurality of the mounting holes 6 are provided and distributed at the positions to be fixed on the second back plate; the back shell buckle 7 includes a bottom plate 9, a turntable block 10, a rotating shaft, and a hook 12; a turntable block 10 is installed at the middle position of the bottom surface of the bottom plate 9 through the rotating shaft, and a set of oppositely arranged hooks 12 are respectively installed on both sides of the top surface along the corresponding positions of the turntable block 10 as the center point; wherein the shape of the turntable block 10 is adapted to the mounting hole 6, and it can be placed into the hole along the opening direction of the mounting hole 6 and cannot be taken out along the mounting hole 6 after rotating 90°.
[0024] See Figure 4 As shown, the mounting hole 6 is a rectangular hole with a length of d1 and a width of d2, and the turntable block 10 is a rectangular structure, wherein the length of the rectangle of the turntable block 10 < d1 and the width < d2.
[0025] See Figures 5-6 As shown, the back shell buckle 7 further includes a gripper seat 8, a stop portion 11, and an extension platform 14; two gripper seats 8 are provided and are respectively symmetrically installed on both sides of a pair of hooks 12 away from the center point and close to the extension platform 14; the extension platform 14 is located at both ends of the bottom plate 9; two stop portions 11 are provided and are respectively independently installed at the bottoms of the two extension platforms 14.
[0026] Further, the extension platform 14 is an elastic structure, and when the two gripper seats 8 approach or loosen relative to each other, the extension platform 14 can bend upward or downward; the stop portion 11 is installed in a limiting and clamping manner with the mounting hole 6, wherein the short side direction is the limit, and the long side direction is tightly against the edge of the opening of the second back plate.
[0027] See Figure 5 As shown, it further includes two reinforcing plates 13, which are respectively independently used to connect the side surface of each hook 12 and the top surface of the bottom plate 9.
[0028] See Figure 3 As shown, after the structure in the present utility model is installed, it can replace the corresponding 2 screws on 8 buckles in the prior art, and 16 screws can be saved. At the same time, the operation is simple, and the installation efficiency is greatly improved. For the specific screw-free assembly installation process, see the following embodiment.
[0029] Embodiment 1
[0030] Put the turntable block 10 on the rear shell buckle 7 into the hole along the length direction of the mounting hole 6, and then rotate the buckle 90°, so that the turntable block 10 blocks in the width direction of the mounting hole 6. Then move the two gripper seats 8 closer to each other, driving the extension platform 14 to bend upward. Since the extension platform 14 is an elastic structure, until the stop portion 11 at the bottom of the extension platform 14 enters the mounting hole 6, the clamping connection is achieved. Release the gripper seat 8 to realize the screwless assembly of the second backplane 5 and the rear shell buckle.
[0031] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent.
