Description

Technical Field

[0001] The utility model relates to the technical field of LCD display screens, in particular to a multifunctional LCD liquid crystal intelligent display screen which is easy to maintain. Background Art

[0002] Multifunctional LCD smart display usually refers to an LCD display with multiple functions. This type of display can not only display images and text information, but may also integrate some advanced functions and technical features to meet specific application requirements. It consists of a certain number of color or black and white pixels and is placed in front of a light source or a reflective surface. LCD displays have very low power consumption and are therefore favored by engineers. They are suitable for battery-powered electronic devices. Its main principle is to use electric current to stimulate liquid crystal molecules to generate points, lines, and surfaces that cooperate with the back light tube to form a picture.

[0003] The existing LCD liquid crystal intelligent display screen inserts the display screen body into the placement slot and is tightly attached to the rear end of the soft pad connected to the placement slot, and the two pressure plates are tightly attached to the rear end left and rear end right of the display screen body respectively. By tightly attaching the rear shell to the rear end of the frame body, the rear shell squeezes the spring, causing the spring to contract, thereby pushing the pressure plate to press the display screen body through the rebound force of the spring, so that the display screen body is fixed between the soft pad and the two pressure plates, and then the positioning rod is passed through the through-slot from the rear end of the block and is connected to the through-slot together, and at the same time, the rear end of the positioning rod is stored in the storage slot, and the fastening nut is connected to the front outer surface of the positioning rod through the thread, and the fastening nut is inserted in the front of the through-slot block for storage, so that the device is easy to assemble and easy to repair and replace.

[0004] Existing disassembly methods often require the use of multiple tools such as screwdrivers and wrenches, which increases the time and complexity of repair preparation. Each disassembly requires unscrewing fasteners one by one, which is not only time-consuming and labor-intensive, but also easily leads to damage or loss of fasteners in the case of frequent disassembly and assembly.

[0005] Therefore, it is necessary to provide a new multifunctional LCD liquid crystal intelligent display screen that is easy to maintain to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a multifunctional LCD intelligent display screen which is easy to maintain.

[0007] The multifunctional LCD intelligent display screen provided by the utility model is easy to maintain and comprises a display screen body, a protective frame located in front of the display screen body, and a mounting device located in the rear of the display screen body. The four outer corners of the protective frame and the mounting device are respectively provided with limit assemblies.

[0008] The limiting assembly includes a plurality of rectangular protrusions fixedly connected to the four corners of the outside of the protective frame and a plurality of rectangular frames fixedly connected to the four corners of the outside of the mounting device. A rectangular groove is provided on the rectangular protrusion, and a connecting frame is fixedly connected to the side of the rectangular frame away from the mounting device. A sliding groove is provided on the top of the connecting frame. The top edge of the connecting frame is fixedly connected to the limiting block, and a spring 1 is fixedly connected to the side wall of the connecting frame. The limiting protrusion is fixed to the end of the spring 1 away from the connecting frame. The limiting protrusion can extend into the rectangular groove of the rectangular protrusion, and the top of the limiting protrusion is slidably connected to the limiting rod. The limiting rod extends out of the sliding groove of the connecting frame and is fixedly connected to the limiting plate. The bottom of the limiting plate is provided with a limiting groove matching the limiting block.

[0009] Furthermore, a flush groove is formed through the rectangular frame and the connecting frame, and the limiting protrusion can slide on the inner side wall of the flush groove.

[0010] Furthermore, both ends of the inner wall of the connecting frame are respectively fixedly connected with horizontal rods, and the side walls of the limiting protrusions are provided with horizontal holes that are slidably connected to the outer surfaces of the horizontal rods.

[0011] Furthermore, an annular hole is provided on the top of the limiting protrusion, and the bottom of the outer surface of the limiting rod can slide vertically along the side wall of the annular hole of the limiting protrusion.

[0012] Furthermore, a glass plate is fixedly connected to the inner side wall of the protective frame, and a soft cushion is provided between the protective frame and the display screen body.

[0013] Furthermore, the mounting device includes a rear shell, the four outer corners of the rear shell are fixedly connected to four rectangular frames, multiple springs are fixedly connected to both sides of the inner wall of the rear shell, and one end of the multiple springs away from the rear shell is fixedly connected to a pressure plate, which is arranged to fit the rear side of the display screen body.

[0014] Compared with the related art, the multifunctional LCD intelligent display screen that is easy to maintain provided by the present invention has the following beneficial effects:

[0015] The multifunctional LCD intelligent display screen which is easy to maintain applies a tensile force in the direction of the spring to the limit plate, so that the limit plate drives the limit rod and the limit protrusion to move synchronously. After the movement, the limit protrusion will disengage from the rectangular groove of the rectangular protrusion and squeeze the spring 1 on the rear side. Then, the limit rod is lifted up in advance, so that the limit rod moves accordingly. After the limit plate is lifted to a position higher than the limit block, the limit plate is continued to be pushed until the limit groove reaches the bottom of the limit block. By moving the limit plate down to be flush with the bottom of the limit block, the limit block is docked with the limit groove through the squeezing force released by the spring 1, and the position of the limit protrusion is fixed. By operating the limit protrusions at the four corners as described above, the protective frame can be separated from the mounting device, so that the display screen body inside can be repaired. The protective frame and the mounting device for limiting the display screen body can be separated by simply pulling, thereby reducing the use of operating tools and improving maintenance efficiency.

[0024] In the specific implementation process, Figures 1 to 5 As shown, the multifunctional LCD intelligent display screen provided by the present invention, which is easy to maintain, comprises a display screen body 1, a protective frame 2 located in front of the display screen body 1, and a mounting device located in the rear of the display screen body 1. The four outer corners of the protective frame 2 and the mounting device are respectively provided with limit assemblies;

[0025] The limiting assembly includes a plurality of rectangular protrusions 3 fixedly connected to the four outer corners of the protective frame 2 and a plurality of rectangular frames 5 fixedly connected to the four outer corners of the mounting device. A rectangular groove is provided on the rectangular protrusion 3. The side of the rectangular frame 5 away from the mounting device is fixedly connected to the connecting frame 8. A sliding groove 10 is provided on the top of the connecting frame 8. The top edge of the connecting frame 8 is fixedly connected to the limiting block 9. The side wall of the connecting frame 8 is fixedly connected to a spring 11. The end of the spring 11 away from the connecting frame 8 is fixed with a limiting protrusion 12. The limiting protrusion 12 can extend into the rectangular groove of the rectangular protrusion 3. The top of the limiting protrusion 12 is slidably connected to the limiting rod 13. The limiting rod 13 extends out of the sliding groove 10 of the connecting frame 8 and is fixedly connected to the limiting plate 14. The bottom of the limiting plate 14 is provided with a limiting groove matching the limiting block 9.

[0026] When the display screen body 1 is repaired, the limit plate 14 is stretched in the direction of the spring 11, so that the limit plate 14 drives the limit rod 13 and the limit protrusion 12 to move synchronously. After the movement, the limit protrusion 12 will disengage from the rectangular groove of the rectangular protrusion 3 and squeeze the spring 11 on the rear side. Then, the limit rod 13 is lifted up in advance, so that the limit rod 13 moves accordingly. After the limit plate 14 is lifted up to a position higher than the limit block 9, the limit plate 14 is continued to be pushed until the limit groove reaches the bottom of the limit block 9. By moving the limit plate 14 down to be flush with the bottom of the limit block 9, the extrusion force released by the spring 11 makes the limit block 9 dock with the limit groove, completing the position fixing of the limit protrusion 12. By operating the limit protrusions 12 at the four corners as described above, the rectangular protrusion 3 of the protective frame 2 can be separated from the rectangular frame 5 of the mounting device, thereby allowing the display screen body 1 inside to be repaired.

[0027] During installation after maintenance, the rectangular protrusion 3 is docked with the rectangular frame 5, and then the limit plate 14 is further pushed forward and separated from the limit block 9, and then the limit plate 14 is lifted and the limiting protrusion 12 is re-extended into the rectangular groove of the rectangular protrusion 3 through the extrusion force of the spring 11. By docking the rectangular protrusions 3 at the four corners with the rectangular frame 5, the vertical and horizontal directions of the display screen body 1 are limited, thereby reducing its shaking.

[0028] When the limiting plate 14 is connected to the limiting block 9, the free space of the limiting groove is larger than the limiting area of the limiting block 9, so as to avoid the limiting plate 14 from getting stuck when it is moved out;

[0029] A flush groove is formed through the rectangular frame 5 and the connecting frame 8, and the limiting protrusion 12 can slide on the inner side wall of the flush groove;

[0030] The flush groove allows the limiting protrusion 12 to pass through and connect with the rectangular groove of the rectangular protrusion 3.

[0031] The two ends of the inner wall of the connecting frame 8 are respectively fixedly connected with horizontal rods 15, and the side wall of the limiting protrusion 12 is provided with a horizontal hole that is slidably connected to the outer surface of the horizontal rod 15;

[0032] During the reciprocating motion of the horizontal rod 15 on the limiting protrusion 12, the limiting protrusion 12 maintains a horizontal trajectory to avoid deviation;

[0033] An annular hole is formed on the top of the limiting protrusion 12, and the bottom of the outer surface of the limiting rod 13 can slide vertically along the side wall of the annular hole of the limiting protrusion 12;

[0034] A glass plate 6 is fixedly connected to the inner wall of the protective frame 2, and a soft pad 7 is provided between the protective frame 2 and the display screen body 1. The transparent material of the glass plate 6 facilitates viewing of the rear display screen body 1, and the provision of the soft pad 7 avoids direct contact with the display screen body 1, thereby increasing its service life.

[0035] The mounting device includes a rear housing 16, the four outer corners of the rear housing 16 are fixedly connected to the four rectangular frames 5, and a plurality of springs 17 are fixedly connected to both sides of the inner wall of the rear housing 16. The ends of the plurality of springs 17 away from the rear housing 16 are fixedly connected to a pressure plate 4, and the pressure plate 4 is arranged to fit the rear side of the display body 1;

[0036] The working principle of the present invention is as follows: in the specific implementation of the present invention, when the display screen body 1 is repaired, the limit plate 14 is subjected to a tensile force in the direction of the spring 11, so that the limit plate 14 drives the limit rod 13 and the limit protrusion 12 to move synchronously, and the limit protrusion 12 will disengage from the rectangular groove of the rectangular protrusion 3 after moving, and squeeze the spring 11 on the rear side, and then the limit rod 13 is lifted up in advance, so that the limit rod 13 moves accordingly, and after the limit plate 14 is lifted up to a position higher than the limit block 9, the limit plate 14 is continued to be pushed until the limit groove reaches the bottom of the limit block 9, and the limit plate 14 is moved down to be flush with the bottom of the limit block 9, and then the extrusion force released by the spring 11 makes the limit block 9 dock with the limit groove, completing the position fixing of the limit protrusion 12, and by operating the limit protrusions 12 at the four corners as described above, the rectangular protrusion 3 of the protective frame 2 can be separated from the rectangular frame 5 of the mounting device, so that the display screen body 1 inside can be repaired;

[0037] During installation after maintenance, the rectangular protrusion 3 is docked with the rectangular frame 5, and then the limit plate 14 is further pushed forward and separated from the limit block 9, and then the limit plate 14 is lifted and the limiting protrusion 12 is re-extended into the rectangular groove of the rectangular protrusion 3 through the extrusion force of the spring 11. By docking the rectangular protrusions 3 at the four corners with the rectangular frame 5, the vertical and horizontal directions of the display screen body 1 are limited, thereby reducing its shaking.
