[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of 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.

[0022] See also Figure 1-Figure 4 The utility model provides an embodiment: a protective structure for a liquid crystal display screen, comprising a protective frame 1, a limiting groove 2 is provided at the top of the protective frame 1, and flexible limiting blocks 3 are installed on both sides of the limiting groove 2;

[0023] The cross section of the flexible limit block 3 is a right-angle trapezoid, and the inclined surface of the flexible limit block 3 faces the inside of the limit groove 2. The flexible limit blocks 3 are distributed at equal intervals on the limit groove 2;

[0024] Specifically, Figure 1 and Figure 4 As shown, when in use, the flexible limit block 3 is used to limit the two sides of the liquid crystal display screen, and under the action of the inclined surface, the bottom end of the liquid crystal display screen can be supported by the flexible limit block 3 to reduce the direct impact between the liquid crystal display screen and the bottom end of the limit groove 2 during the placement process;

[0025] Through holes 4 are provided on the other two sides of the limiting groove 2, and the inside of the through holes 4 penetrates the limiting plate 5;

[0026] The limiting plate 5 forms a left-right sliding structure with the limiting groove 2 through the through hole 4. The first chamfered surface 18 and the second chamfered surface 19 together form a triangular inclined surface on the limiting plate 5. The cross-sectional length of the second chamfered surface 19 is greater than the cross-sectional length of the first chamfered surface 18. An anti-slip pad is provided on one side of the second chamfered surface 19.

[0027] Specifically, Figure 1 , Figure 2 As shown, when in use, the first chamfered surface 18 is used to facilitate the placement of the LCD screen. The gravity of the first chamfered surface 18 automatically pushes the two limit plates 5 outward, and then the LCD screen successfully enters the inside of the limit groove 2. At the same time, the elasticity of the structural spring 14 and the structural effect of the second chamfered surface 19 can achieve the clamping and fixing of the other two sides of the LCD screen, and generate a blocking effect on the top of the LCD screen to prevent the screen from popping up and moving upward;

[0028] A fixing plate 12 is installed on both sides of the limiting plate 5, and a limiting guide column 13 is installed on one side of the fixing plate 12. One end of the limiting guide column 13 passes through one side of the protective frame 1. A spring 14 is sleeved on the outside of the limiting guide column 13, and one end of the spring 14 is against the inner wall of the limiting groove 2. The spring 14 is used to push the limiting plate 5 toward the inner end of the limiting groove 2 and squeeze the side wall of the display screen. A first chamfered surface 18 is provided on the inner side of the top of the limiting plate 5, and a second chamfered surface 19 is provided on the inner side of the bottom end of the limiting plate 5, and the second chamfered surface 19 is against the side wall of the display screen. A top protective structure is provided on the outer side of the protective frame 1;

[0029] The top protection structure includes two groups of guide grooves 6 respectively opened at the bottom end of the outer side of the protection frame 1, and the first movable frame 7 and the second movable frame 8 are evenly connected between the guide grooves 6, the first movable frame 7 and the second movable frame 8 are symmetrically distributed about the central axis of the guide groove 6, the top ends of the outer sides of the first movable frame 7 and the second movable frame 8 are both opened with grooves 9, and rollers 10 are installed inside the grooves 9, and the outer sides of the rollers 10 are both covered with protective cloth 11, and one side of the protective cloth 11 is connected to the top of the protection frame 1;

[0030] The first movable frame 7 and the second movable frame 8 both form a front-to-back sliding structure through the guide groove 6 and the protection frame 1. The inner sides of the first movable frame 7 and the second movable frame 8 are both located on the outer sides of the limit plate 5. When the first movable frame 7 and the second movable frame 8 are close to each other, they have a blocking effect on the outer side of the limit plate 5.

[0031] Positioning rods 15 are installed on both sides of the first movable frame 7, and L-shaped rotating pins 16 are installed on both sides of the second movable frame 8. A clamping groove 17 is opened on one side of the L-shaped rotating pin 16. The L-shaped rotating pin 16 forms a buckle structure with the positioning rod 15 through the clamping groove 17.

[0032] Specifically, Figure 1 , Figure 3 As shown, when in use, the first movable frame 7 and the second movable frame 8 are connected close to each other, so that they can further block the outer side of the limiting plate 5 to prevent the limiting plate 5 from moving outward, thereby ensuring the limiting stability of the liquid crystal display screen inside the limiting groove 2;

[0033] The unfolded length of the protective cloth 11 matches half of the width of the protective frame 1 , and the width of the protective cloth 11 matches the length of the protective frame 1 ;

[0034] Specifically, Figure 1 As shown, when in use, the protective cloth 11 is utilized to provide dustproof shielding for the top of the protective frame 1, so as to further improve the protective effect.

[0035] Working principle: When the utility model is used, the LCD screen is first placed into the limiting groove 2 from top to bottom, so that the bottom end of the LCD screen slides downward along the inclined surface of the flexible limiting block 3 and the inclined surface of the first chamfered surface 18, and the flexible limiting block 3 is used to perform preliminary limiting on both sides of the LCD screen;

[0036] Secondly, when the LCD screen moves out of the first chamfered surface 18, the spring 14 exerts an inward pushing force on the fixing plate 12 under the elastic action, and then the limiting plate 5 is pressed inward along the through hole 4, so that the second chamfered surface 19 presses the other two sides of the LCD screen. The special structure of the second chamfered surface 19 is used to block the top of the LCD screen, prevent the LCD screen from moving upward, and improve the limiting effect.

[0037] Finally, the first movable frame 7 and the second movable frame 8 are brought closer to each other along the guide groove 6. Since one end of the protective cloth 11 is fixedly connected to the top of the protective frame 1, the movement of the first movable frame 7 and the second movable frame 8 causes the roller 10 to rotate, thereby driving the protective cloth 11 to unfold. When the first movable frame 7 and the second movable frame 8 are attached to each other, the L-shaped rotating pin 16 is flipped so that the L-shaped rotating pin 16 is placed on the positioning rod 15 and the positioning rod 15 is inserted into the inside of the card slot 17 to achieve the connection and fixation between the first movable frame 7 and the second movable frame 8, so that the protective cloth 11 blocks and protects the top of the protective frame 1, and the first movable frame 7 and the second movable frame 8 are used to further block the outer side of the limit plate 5, thereby ensuring the stability of the limit fixation of the LCD screen in the limit groove 2.
