[0002] Among electronic products, LCD screens are a display technology widely used in electronic devices such as televisions, computer monitors, mobile phones, and tablets. It controls the proportion of light passing through by adjusting the arrangement of liquid crystal molecules, and then cooperates with color filters to display different colors and images.
[0003] As an important component, the LCD screen should be protected. At present, screws are still widely used in the production process. However, due to factors such as processing accuracy and defects in production tools, the LCD screen will be squeezed by screws, which may cause potential damage to components with high precision requirements and relatively fragile components that are easy to ignore. Due to the squeezing force of the screws on the LCD screen, the LCD screen may be damaged again in harsh environments such as bumpy roads and high temperatures during transportation.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.
[0018] See also Figure 1-4The utility model provides a technical solution: including a loading shell 1 and a liquid crystal screen body 2, a positioning frame 3 is fixed in the loading shell 1, the inner diameter of the positioning frame 3 is adapted to the size of the liquid crystal screen body 2, a bearing baffle 4 is fixed on the front side of the inner wall of the positioning frame 3, a pair of corner buckle plates 5 are installed on the rear side of the bottom of the positioning frame 3, a pair of elastic buckles 6 are fixed on the upper rear side of the positioning frame 3, the liquid crystal screen body 2 is located in the positioning frame 3, and is located between the elastic buckle 6 and the corner buckle plates 5, plastic tapes 7 are fixed at the middle positions on both sides of the positioning frame 3, contact ribs 71 are fixed at the middle position on the inner side of the plastic tape 7, and the inner side of the contact ribs 71 is against the side wall of the liquid crystal screen, and rear cover screw holes 11 are provided at the four corners of the loading shell 1.
[0019] The corner gusset plate 5 is slidably connected to the rear side of the positioning frame 3, and a fixed frame 51 is fixed on the outside of the positioning frame 3. A telescopic block 52 is slidably connected inside the fixed frame 51. The upper end of the telescopic block 52 extends out of the fixed frame 51 and abuts against the rear side of the corner gusset plate 5. A spring is arranged in the fixed frame 51, and the spring is fixed between the bottom of the telescopic block 52 and the inner wall of the fixed frame 51. A pair of limiting slide bars 53 are fixed at the upper end of the fixed frame 51 and at the position corresponding to the corner gusset plate 5. The limiting slide bar 53 is a T-shaped structure, and a pair of limiting grooves are arranged at the bottom of the corner gusset plate 5. The limiting slide bar 53 is slidably connected in the limiting grooves.
[0020] Working principle: First, insert the bottom two corners of the LCD screen body 2 into the fixed frame 51 and the corner buckle plate 5, and then press its upper end into the fixed frame 51, and use the deformation of the elastic buckle 6 to fix it in the positioning frame 3. During the overall installation process, no screws are required for fixing, and the operation is relatively simple. At the same time, since plastic tapes 7 are provided on both sides of the fixed frame 51, the elastic deformation of the plastic tapes 7 can be used to eliminate and release the pressure on the LCD screen in any direction when the shape of the fixed frame 51 is deformed, thereby improving safety. During the loading process, if the size of the LCD screen body 2 is too close to the positioning frame 3, the LCD screen body 2 can only be inserted horizontally. When positioning the frame 3, the LCD screen body 2 can be placed horizontally in the positioning frame 3 by utilizing the sliding of the corner buckle plate 5 and the elastic deformation of the elastic buckle 6, and then the LCD screen body 2 can be fixed by resetting the corner buckle plate 5 and the elastic buckle 6. The entire process avoids pressing down on the LCD screen body 2, thereby further improving safety. During this process, the elastic buckle 6 can be deformed by external force. When the corner buckle plate 5 needs to slide, the telescopic block 52 can be pressed down so that its end is accommodated in the groove fixing frame 51, thereby allowing the corner buckle plate 5 to slide freely. Conversely, after the corner buckle plate 5 is reset, the end of the corner buckle plate 5 can be blocked by extending the telescopic block 52 to fix the position of the corner buckle plate 5.
