Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display technology, and more specifically, to a liquid crystal display with protective functions. Background Technology

[0002] Liquid crystal displays (LCDs) play a wide and important role in modern life and various fields. The core component of an LCD is the liquid crystal panel, which is typically composed of two glass substrates sandwiching liquid crystal molecules. Glass itself is a brittle material with poor impact resistance. When subjected to external impacts, the glass substrate is prone to breakage, cracks, and other damage, thus affecting the normal display function of the screen.

[0003] Current LCD screens have a relatively simple and exposed structure, which means that when they come into contact with external objects, pressure and impact are directly transmitted to the glass substrate of the LCD panel. Once the glass substrate exceeds its bearing capacity, it will break and liquid crystal molecules will leak out, causing the LCD screen to be damaged and unusable. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a liquid crystal display screen with protective function to solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0006] A protective liquid crystal display screen includes a liquid crystal display screen body, a protective frame fixedly installed on the side of the liquid crystal display screen body, and evenly distributed mounting posts fixedly installed on the inner side of the protective frame. A protective plate is provided on the front of the liquid crystal display screen body, the protective plate being located inside the protective frame. A stop post is rotatably installed on the back of the protective plate. A threaded sleeve is slidably installed inside the mounting post. A spring is fixedly installed between the threaded sleeve and the inner wall of the mounting post. One end of the back of the stop post is threadedly connected to the threaded sleeve. A piston is slidably installed on the inner side of the stop post, and a push rod is fixedly installed on the piston, the push rod extending to the outside of the stop post.

[0007] As a further description of the above technical solution:

[0008] The protective panel consists of a mounting frame and a transparent panel. The transparent panel is fixedly installed on the inner side of the mounting frame and is made of either transparent glass or transparent acrylic sheet.

[0009] As a further description of the above technical solution:

[0010] A rubber buffer ring is fixedly installed on the back of the mounting frame, and the back of the rubber buffer ring is in contact with the main body of the liquid crystal display screen.

[0011] As a further description of the above technical solution:

[0012] The front of the abutment extends through and to the front of the mounting frame, and a cross groove is provided on the front of the abutment.

[0013] As a further description of the above technical solution:

[0014] The threaded sleeve has integrally formed limiting slides on both sides, and the mounting post has limiting grooves on both sides inside. The two limiting slides are located inside the two limiting grooves respectively and are slidably connected to the inner wall of the limiting grooves.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] In this design, the force on the protective plate is transmitted to the spring through the abutment and mounting post for initial buffering. When the push rod contacts the inner wall of the mounting post, the piston moves and compresses the air inside the abutment, further buffering the impact or pressure of the collision. This prevents the LCD screen from being damaged by the squeezing or collision of external objects, thus providing better protection and ensuring the normal use of the LCD screen.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-3In this utility model, a liquid crystal display screen with protective function includes a liquid crystal display screen body 1, a wrapping frame 2 fixedly installed on the side of the liquid crystal display screen body 1, and evenly distributed mounting posts 3 fixedly installed on the inner side of the wrapping frame 2. A protective plate 4 is provided on the front of the liquid crystal display screen body 1, and the protective plate 4 is located inside the wrapping frame 2. A stop post 5 is rotatably installed on the back of the protective plate 4. A threaded sleeve 6 is slidably installed inside the mounting post 3. A spring 7 is fixedly installed between the threaded sleeve 6 and the inner wall of the mounting post 3. One end of the back of the stop post 5 is threadedly connected to the threaded sleeve 6. A piston 8 is slidably installed on the inner side of the stop post 5. A push rod 9 is fixedly installed on the piston 8 and extends to the outside of the stop post 5.

[0024] In this invention, the enclosure frame 2 and the protective plate 4 are used to enclose the main body 1 of the LCD screen, preventing external objects from directly colliding with the main body 1 and thus protecting the main body 1. When the front of the main body 1 of the LCD screen is subjected to pressure or collision, the object first contacts the protective plate 4 and squeezes it. Since the protective plate 4 is fixed by the threaded connection between the abutment 5 and the threaded sleeve 6 on the inner side of the mounting post 3, the force on the protective plate 4 is transmitted to the spring 7 through the abutment 5 and the mounting post 3 for initial buffering. Until the top rod 9 contacts the inner wall of the mounting post 3, the piston 8 moves to compress the air inside the abutment 5, further buffering the impact force or pressure, preventing the main body 1 of the LCD screen from being damaged by the squeezing or collision of external objects, thus providing better protection and ensuring the normal use of the main body 1 of the LCD screen.

[0025] Please see Figure 1-3 The protective plate 4 consists of a mounting frame 41 and a transparent plate 42. The transparent plate 42 is fixedly installed on the inner side of the mounting frame 41 and is made of either transparent glass or transparent acrylic sheet.

[0026] In this utility model, the mounting frame 41 facilitates the installation of the support column 5, while the transparent plate 42 covers the front of the LCD screen body 1 without hindering the display and use of the LCD screen body 1.

[0027] Please see Figure 3 Among them, a rubber buffer ring 43 is fixedly installed on the back of the mounting frame 41, and the back of the rubber buffer ring 43 is in contact with the main body 1 of the liquid crystal display screen.

[0028] In this invention, the rubber buffer ring 43 can seal the gap between the mounting frame 41 and the LCD screen body 1, preventing external dust from directly entering and affecting the display effect of the LCD screen body 1. At the same time, it can also play a buffering role, preventing the mounting frame 41 from directly contacting the LCD screen body 1.

[0029] Please see Figure 1-3The front of the abutment 5 extends through and to the front of the mounting frame 41, and a cross groove 51 is provided on the front of the abutment 5.

[0030] In this utility model, the cross groove 51 on the front of the abutment 5 makes it easy to rotate the abutment 5 by operating a tool, thereby facilitating the threaded connection between the abutment 5 and the threaded sleeve 6.

[0031] Please see Figure 3 Among them: the threaded sleeve 6 has integrally formed limiting slide strips 61 on both sides, and the two sides inside the mounting column 3 are opened in limiting slide grooves 31. The two limiting slide strips 61 are located inside the two limiting slide grooves 31 respectively, and are slidably connected to the inner wall of the limiting slide grooves 31.

[0032] In this invention, by restricting the inner wall of the sliding groove 31 and the sliding strip 61, the threaded sleeve 6 is prevented from rotating inside the mounting post 3, thus ensuring that the threaded sleeve 6 can be stably threadedly connected to the abutment post 5.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
