[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] A type of LCD screen, such as Figure 5 As shown, the device includes a front frame 1, a back frame 3 mounted on the back of the front frame 1, and a mounting cavity formed between the front frame 1 and the back frame 3. A screen assembly 2 is mounted in the mounting cavity. A connection terminal 4 is provided on the back frame 3 for wiring the LCD screen. The front frame 1 and the back frame 3 form the outer frame of the LCD screen. The screen assembly 2 includes a screen and some electronic components, which are mounted in the mounting cavity. The connection terminal 4 then connects the electronic components in the LCD screen to power or signal sources.

[0026] A liquid crystal display (LCD) mounting structure, such as Figures 1-4 As shown, the device includes a mounting base 11 for supporting an LCD screen. The mounting base 11 is vertically arranged, and a supporting moving component is provided at the bottom of the mounting base 11. The supporting moving component can drive the mounting base 11 to move and can adjust the height of the mounting base 11. The mounting base 11 is provided with a clamping component, which is provided in multiple sets. The clamping component includes two sets of L-shaped clamping plates 13. The two sets of clamping plates 13 are slidably installed at the upper and lower ends of the mounting base 11, respectively. First, the ends of the clamping plates 13 are controlled to move away from the mounting base 11, increasing the space between the ends of the clamping plates 13 and the mounting base 11. The LCD screen is inserted from one side of the mounting base 11 between the multiple sets of clamping plates 13. Then, the ends of the clamping plates 13 are controlled to move closer to the mounting base 11, so that the ends of the clamping plates 13 slightly squeeze the LCD screen, so that the LCD screen is clamped between the clamping plates 13 and the mounting base 11, and the front of the LCD screen is in close contact with the mounting base 11. The mounting base 11 is provided with a driving component for driving the clamping plates 13 to slide.

[0027] An electric drive component drives the clamping component to operate, clamping the LCD screen between the clamping plate 13 and the loading seat 11 to support the LCD screen. Then, a support and moving component is used to easily move the loading seat 11 with the LCD screen clamped to the installation position and adjust the height of the screen. The whole process does not require manual lifting of heavy objects for a long time, which greatly reduces the physical exertion and operation difficulty of the installers.

[0028] A protective pad 12 is attached to one side of the loading seat 11. The protective pad 12 is located between the loading seat 11 and the LCD screen. The card plate 13 is L-shaped, and a protective pad 2 14 is fixed to one end of the inner wall of the card plate 13.

[0029] Protective pad 12 and protective pad 2 14 are made of soft and elastic rubber or foam material. Their function is to prevent the hard mounting base 11 body from directly contacting and scratching the front screen of the LCD screen, to prevent the LCD screen from slipping or shaking during movement and adjustment, and to effectively prevent the card plate 13 from scratching or squeezing the LCD screen frame.

[0030] The drive assembly includes a shaft 15, which is rotatably mounted in a bearing seat. Both ends of the shaft 15 are fixedly connected to driven gears 16. One side of the clamping plate 13 is provided with teeth, and the driven gears 16 mesh with the teeth for transmission.

[0031] The back of the loading seat 11 has a groove 17, and a servo motor 18 (model MSMF042L1U2M) is fixedly connected in the groove 17. The output end of the servo motor 18 is fixedly connected to the drive gear 19, and the drive gear 19 meshes with the driven gear 16 for transmission.

[0032] The output of the servo motor 18 drives the drive gear 19, which in turn meshes with the driven gear 16, thereby driving the shaft 15 to rotate. This causes another set of driven gears 16 to rotate, and each set of driven gears 16 that meshes with the teeth on the side of the clamping plate 13 rotates. The driven gears 16 drive the clamping plate 13 to slide, so that the clamping plate 13 holds the LCD screen. The distance between the upper and lower clamping plates 13 corresponds to the height of the LCD screen.

[0033] The supporting moving component includes a base 5, with multiple sets of universal wheels 6 installed at the bottom of the base 5. A support column 7 is fixedly connected to the upper end of the base 5, and an adjusting column 8 is slidably installed at the upper end of the support column 7. A lifting cylinder for lifting the adjusting column 8 is provided inside the support column 7, and a mounting seat 9 is fixedly connected to the upper end of the adjusting column 8. The mounting seat 9 is fixedly connected to the back of the loading seat 11.

[0034] The back of the loading seat 11 is securely connected to the mounting seat 9 by bolts. The mounting seat 9 is fixed to the top of the supporting moving assembly. The supporting moving assembly includes a rectangular base 5. Each of the four corners of the bottom of the base 5 is equipped with a caster 6 with a braking function, such as a heavy-duty caster 6 from the CITIC Pacific brand, to facilitate the movement and fixation of the entire device. A support column 7 is vertically welded to the center of the base 5. An adjusting column 8 is inserted into and slides inside the support column 7 and can slide up and down relative to the support column 7. A lifting cylinder (model SDA50x200-LB) is installed inside the support column 7, which can provide stable thrust and pull. The cylinder body of the lifting cylinder is fixed to the bottom of the support column 7, and the top of its piston rod is connected to the bottom of the adjusting column 8. When the cylinder is vented, it can push the adjusting column 8 and the entire loading seat 11 and the LCD screen at its top to rise or fall smoothly, thereby precisely adjusting the installation height of the LCD screen.

[0035] The present invention provides an LCD screen mounting structure and the working principle of the LCD screen as follows:

[0036] Start the servo motor 18 in the drive assembly to slide the L-shaped clamping plate 13 outward, leaving enough space for placement. Place the back of the LCD screen against the protective pad 12 of the loading seat 11 and insert the LCD screen between multiple sets of clamping plates 13. Then control the servo motor 18 to reverse and drive the upper and lower clamping plates 13 to slide inward until the ends of the clamping plates 13 hook onto the upper and lower edges of the LCD screen and are tightly clamped and fixed by the protective pad 14. After the LCD screen is fixed, the operator can push the entire installation structure and move it to the predetermined installation position by the casters 6 under the base 5 and lock the casters 6. Operate the lifting cylinder to drive the adjusting column 8 to raise and lower the LCD screen on the loading seat 11 until the connecting end 4 on the back frame 3 of the LCD screen is completely aligned with the pre-installed bracket on the wall. The installation of the LCD screen does not require manual lifting of heavy objects for a long time, which greatly reduces the physical exertion and operation difficulty of the installers.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
