[0002] A liquid crystal display is generally composed of a liquid crystal module, a front frame, a rear cover, and a base. During installation, the liquid crystal module is installed on the front frame by bolts, the rear cover is fixed to the front frame by bolts, and the base is fixedly connected to the rear cover. The liquid crystal module is constructed with screw holes for the bolts to pass through. When the screws are tightened, the liquid crystal module can be fastened to the front frame. Once the screws are loosened, the liquid crystal module can swing up and down (the reason is that the screw diameter of the bolt is smaller than the screw hole diameter on the liquid crystal module. Once loosened, the liquid crystal module will inevitably swing up and down and left and right).

[0003] When the display needs to be moved or packed for transportation, the glass screen of the LCD module may be shaken up and down and hit the inner edge of the front frame, causing the corners of the glass screen to be damaged (people hold the outer shell during transportation, and after the screws are loosened, there is shaking between the glass screen of the LCD module and the outer shell, so the corners are easily damaged).

[0004] To solve this problem, the present application proposes a protective device for improving the damage of the corners of a liquid crystal display. Summary of the invention

[0005] The purpose of the utility model is to prevent the possibility of damage to the corners of the glass screen of the liquid crystal module due to the shaking between the liquid crystal module and the shell after the screws of the liquid crystal display are loosened, and the collision with the inner edge of the front frame.

[0008] The four outer walls of the annular frame are tightly pressed against the four inner walls of the front frame, and the inner wall of the annular frame is tightly pressed against the four sides of the glass screen of the liquid crystal module.

[0009] Furthermore, the four inner corners of the annular frame are provided with pressing bars for pressing against the side surfaces of the glass screen of the liquid crystal module, and an elastic mechanism is constructed between the pressing bars and the annular frame.

[0010] Furthermore, the elastic mechanism includes a plurality of groups of elastic strips which are arranged obliquely and whose head and tail ends are respectively fixed to the strips and the annular frame, and an arc strip which assists the elastic strip in resetting is integrally constructed between the elastic strips and the annular frame.

[0011] Furthermore, fixing plates are integrally constructed at the four corners of the annular frame, the bolt through holes are opened on the fixing plates, and the fixing plates abut against one side of the inner wall of the front frame.

[0012] Furthermore, the fixing plate is provided with an avoidance hole near the glass screen of the liquid crystal module.

[0013] Furthermore, a sponge pad is adhered to the surface of the pressing strip pressing against the liquid crystal module.

[0014] Furthermore, an outer edge of one opposite surface of the annular frame and an edge of the fixing plate are both configured with inclined surfaces, and the outer edge size of one opposite surface of the annular frame and the outer edge size of the fixing plate are larger than the size between the inner walls of the front frame.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0025] The present embodiment provides a protective device for improving the damage of the corners of a liquid crystal display, which is mainly used to prevent the possibility of damage to the corners of the glass screen of the liquid crystal module due to the shaking between the liquid crystal module and the shell after the screws of the liquid crystal display are loosened, and the collision with the inner edge of the front frame. The utility model provides a protective device for improving the damage of the corners of the liquid crystal display, and provides the following technical solutions. Figure 1-Figure 5 Make a detailed description: Example

[0026] A protective device for improving the damage of the corners of a liquid crystal display comprises a ring frame 1 and a bolt through hole 2 constructed on the ring frame 1. The bolt through hole 2 corresponds to the position of the screw through hole on the liquid crystal module and has the same size. Figure 1 , Figure 2 , the screw through hole here corresponds to the bolt through hole 2, and both are used for passing the fastening bolts. When installing, the annular frame 1 is sleeved on the outer side of the glass screen of the liquid crystal module, and the fastening bolts are passed through the screw through hole and the bolt through hole 2 in sequence, and then locked on the front frame (the front frame is the prior art, and screw holes for bolt locking are constructed thereon), thereby achieving installation;

[0027] At the same time, the four outer walls of the annular frame 1 are pressed against the four inner walls of the front frame, so that there is no shaking gap between the annular frame 1 and the front frame. The inner wall of the annular frame 1 is pressed against the four sides of the glass screen of the LCD module, so that there is no shaking gap between the annular frame 1 and the LCD module, and then indirectly, there is no shaking gap between the front frame and the LCD module. Then, even if the bolts are loosened, the glass screen of the LCD module cannot hit the inner wall of the front frame due to the no shaking gap between the front frame and the LCD module, thereby avoiding the problem of corner damage. Here we explain why the glass screen of the LCD module is not directly set to be stuck in the front frame without gap. The reason is: only In order for the glass screen of the LCD module to be stuck in the front frame, there must be a gap (because it cannot be stuck in without a gap). Therefore, the present application achieves a no-shake gap between the annular frame 1 and the front frame by pressing the four outer walls of the annular frame 1 against the four inner walls of the front frame. The inner wall of the annular frame 1 presses against the four sides of the glass screen of the LCD module to achieve a no-shake gap between the annular frame 1 and the LCD module, thereby indirectly achieving a no-shake gap between the front frame and the LCD module, solving the problem of damage to the corners of the glass screen of the LCD module due to shaking between the LCD module and the outer casing after the screws of the LCD display are loosened, and the collision with the inner edge of the front frame causes the damage to the glass screen corners of the LCD module. Example

[0028] This embodiment provides the following technical solution on the basis of the embodiment 1: the inner four corners of the annular frame 1 are all provided with pressing bars 3 against the side of the glass screen of the liquid crystal module, and an elastic mechanism 4 is constructed between the pressing bars 3 and the annular frame 1. By setting the elastic mechanism 4, the pressing bars 3 are pressed against the side of the glass screen of the liquid crystal module. With the existence of the elastic mechanism 4, the pressing bars 3 are pressed against the side of the glass screen of the liquid crystal module, ensuring that there is no shaking gap between the display screen of the liquid crystal module and the annular frame 1. The specific elastic mechanism 4 includes a plurality of groups of inclined settings and The head and tail ends of the clamping strip 3 and the elastic strip 401 of the annular frame 1 are respectively fixed, and an arc strip 402 for assisting the elastic strip 401 in resetting is integrally constructed between the elastic strip 401 and the annular frame 1. When one side of the clamping strip 3 is pressed against the side of the glass screen of the liquid crystal module, the annular frame 1 fixedly connected to the clamping strip 3 through the elastic strip 401 is pressed against the front frame, so that there is no shaking gap between the annular frame 1 and the glass screen of the liquid crystal module. At the same time, in order to avoid overpressure causing damage to the glass screen of the liquid crystal module, a sponge pad 403 is adhered to the surface of the clamping strip 3 that presses against the liquid crystal module.

[0029] In order to achieve a non-shaking gap between the annular frame 1 and the front frame, an outer edge of one opposite surface of the annular frame 1 and an edge of the fixing plate 5 are both configured with an inclined surface 7, and the outer edge size of one opposite surface of the annular frame 1 and the outer edge size of the fixing plate 5 are larger than the size between the inner walls of the front frame. Here, the outer edge size of one opposite surface of the annular frame 1 and the outer edge size of the fixing plate 5 are 0.5 mm larger than the size between the inner walls of the front frame. Please refer to Figure 2 and Figure 3 When the annular frame 1 and the fixing plate are locked to the front frame by the tightening bolts, since the outer edge size of one opposite surface of the annular frame 1 and the outer edge size of the fixing plate 5 are 0.5 mm larger than the size between the inner walls of the front frame, the outer edge of the fixing plate and the outer edge of one opposite surface of the annular frame 1 will be slightly deformed during installation, so that when the annular frame 1 falls into the front frame as a whole, there is no shaking gap between the two. At the same time, the inclined surface 7 is provided to facilitate installation and deformation during installation.

[0030] In this embodiment, the fixing plate 5 is configured with a clearance hole 6 near the glass screen of the liquid crystal module, and the annular frame 1 is configured with a notch 8 corresponding to the clearance hole. Figure 4 , Figure 5 The avoidance hole 6 and the notch 8 are provided to facilitate the installation of the glass screen of the liquid crystal module into the annular frame 1. Figure 5 For example, when installing, place the corner of the glass screen of the LCD module toward the avoidance hole 6, press the resistance bar with your finger and step back, then drop the glass screen of the LCD module into it, and finally release your finger.

[0031] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
