Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Reference Figure 1 , Figure 3 , Figure 4 The utility model provides an embodiment: a special-shaped LCD module for quick assembly of TP, including a support plate 1, the support plate 1 provides support, a frame 4 is placed on the top of the support plate 1, a display screen is arranged in the frame 4 and can be installed with a circuit board 2, a heat sink 7 is installed on the inner wall of the frame 4, the heat sink 7 provides heat dissipation effect, a circuit board 2 is arranged on the top of the frame 4, and a positioning component is arranged on the top of the support plate 1;

[0036] The positioning assembly includes a positioning plate 23, which provides support. The positioning plate 23 is fixedly connected to the left side of the middle part of the top of the support plate 1. The top of the positioning plate 23 is slidably connected to a clamping block 21, and the clamping block 21 can limit the circuit board 2. The positioning plate 23 and the clamping block 21 are elastically connected by a spring 22. When the circuit board 2 is assembled, the inclined surface of the top of the clamping block 21 can be squeezed so that the clamping block 21 moves to the left to squeeze the spring 22. The reverse force of the squeezed spring 22 drives the clamping block 21 to limit the circuit board 2, thereby positioning the circuit board 2.

[0037] Reference Figure 1 , Figure 3 , Figure 4The front surface of the heat sink 7 is provided with heat dissipation holes 71, and there are multiple groups of heat dissipation holes 71. The multiple groups of heat dissipation holes 71 cooperate with the through grooves 6 to quickly dissipate heat. The front top of the frame 4 is provided with a slide groove 51, and the inner wall of the slide groove 51 is plugged with a filter screen 5, and the slide groove 51 is used to place the filter screen 5.

[0038] Reference Figure 1 - Figure 4 The top of the clamping block 21 is set as an inclined plane. By setting the top of the clamping block 21 as an inclined plane, when squeezing the top of the clamping block 21, the clamping block 21 can be moved to the left through the inclined plane to cooperate with the spring 22 to limit the circuit board 2. The clamping block 21 is set to an inverted L shape. By setting the clamping block 21 to an inverted L shape, the circuit board 2 can be clamped and limited. The right bottom end of the clamping block 21 is fixedly connected with a rubber pad 26. The rubber pad 26 is set to a rubber material to prevent the circuit board 2 from being squeezed and damaged. The circuit board 2 contacts the bottom end of the rubber pad 26. The top of the support plate 1 is fixedly connected with a guide column 24 near the front of the positioning plate 23. The top of the guide column 24 is set to an inclined plane. By setting the top of the guide column 24 to an inclined plane, the circuit board 2 can slide along the inclined plane to the middle position, thereby playing a guiding and positioning role, and improving the convenience and accuracy of assembly.

[0039] Furthermore, a sleeve column 3 is fixedly connected to the bottom end of the circuit board 2, a buckle 25 is fixedly connected to the left side of the circuit board 2, a slot 27 is provided on the left side of the frame 4, the buckle 25 is snapped into the inner wall of the slot 27, and the buckle 25 is snapped into the slot 27 to assemble the frame 4 and the circuit board 2, a bolt slot 8 is provided at the top of the frame 4, the bolts can be installed into the bolt slot 8, a through slot 6 is provided on the front surface of the frame 4, and multiple groups of through slots 6 are provided, and multiple groups of through slots 6 cooperate with the heat dissipation holes 71 to play a circulation role and improve the heat dissipation effect, multiple groups of positioning plates 23, clamping blocks 21, and guide columns 24 are provided, and multiple groups of positioning plates 23, clamping blocks 21, and guide columns 24 are symmetrically arranged with the center line of the support plate 1 as the symmetry axis, and multiple groups are provided to improve the stability of the assembly effect.

[0040] Working principle: When in use, the frame 4 is slid to the top of the guide column 24 and then guided to the middle position of the top of the support plate 1 through the inclined surface. Then, the heat sink 7 is installed on the inner wall of the frame 4. At this time, the circuit board 2 is moved so that the circuit board 2 squeezes the inclined surface of the guide column 24 and is guided to the middle position and moves downward. When it is squeezed to the top inclined surface of the clamping block 21, the clamping block 21 moves to the left to squeeze the spring 22. When the circuit board 2 moves, the sleeve column 3 moves and aligns with the bolt groove 8. When the circuit board 2 contacts the top of the frame 4, the reverse force of the spring 22 is squeezed to drive the clamping block 21 to reset and slide, and at the same time drive the rubber pad 26 to reset and clamp at the top of the circuit board 2 to limit the circuit board 2. At the same time, the circuit board 2 drives the buckle 25 to be clamped into the slot 27. At this time, the circuit board 2 can be limited. The positioning effect is played by limiting, which is convenient for the bolt to pass through the sleeve column 3 for installation. At the same time, it can prevent sliding from affecting the installation, thereby improving the installation accuracy.

[0041] The through slots 6 are provided with a plurality of groups of matching heat dissipation plates 7 and a plurality of groups of heat dissipation holes 71 so that the functions can be connected, thereby improving the heat dissipation effect of the LCD module. Meanwhile, the filter screen 5 can be provided to prevent dust from entering, thereby increasing the service life.
