Description

Technical Field

[0001] The utility model relates to the technical field of display devices, in particular to a heat dissipation structure of an LCD display device. Background Art

[0002] An LCD display, or liquid crystal display, is a flat, ultra-thin display device composed of a certain number of color or black and white pixels. It is placed in front of a light source or a reflective surface. It uses the changes in the arrangement of liquid crystal materials under the action of an electric field to affect the polarization state of light, thereby controlling the transmission or blocking of light to display images. LCD display devices have the advantages of low power consumption, small size, light weight, and no radiation. They are widely used in consumer electronic products such as televisions, computer monitors, smart phones, and tablets, as well as instrument display interfaces in industrial control systems.

[0003] In the prior art, LCD display devices typically utilize cooling fans for heat dissipation. However, the cooling fans generally cool the internal components of the LCD display device in a vertical direction. For example, in a laser liquid crystal touch display device with a heat dissipation structure disclosed in Publication No. CN218995832U, the vertical blowing of the cooling fan can easily lead to airflow short-circuiting, and the overheated gas in the display device cannot be properly guided and discharged, thereby failing to fully utilize the heat dissipation structure. Therefore, a heat dissipation structure for an LCD display device is proposed to address the above-mentioned problem. Utility Model Content

[0030] The mounting plate 201 is located on a side away from the extension frame 208 and is fixedly mounted with a sliding sleeve 203 at both ends. A handle 210 is rotatably connected between the outer walls of the two sliding sleeves 203. The bottom end of the handle 210 extends to the bottom of the baffle 204. A cam 211 is fixedly connected to the top of one side of the handle 210. Figure 4 As shown, after the handle 210 rotates 180 degrees counterclockwise, the cam 211 squeezes the push plate 212, as shown in FIG. Figure 3 As shown, the push plate 212 is pressed and moves, driving the positioning shaft 213 to move in a direction away from the sliding sleeve 203;

[0031] The inner wall of one side sliding sleeve 203 is slidably connected with a positioning shaft 213, one end of the positioning shaft 213 extends into the interior of the sliding sleeve 203, and the other end of the positioning shaft 213 is fixedly connected to a push plate 212, and the surface of the push plate 212 is fixedly connected with a spring 214, which is sleeved on the outer side of the positioning shaft 213, and the side of the spring 214 is also fixedly connected to the sliding sleeve 203.
