Description

Technical Field

[0001] This utility model relates to the field of LCD TVs, and in particular to a LCD TV mounting bracket. Background Technology

[0002] An LCD TV is a type of television that uses liquid crystal display technology. Liquid crystal is a special substance that, under certain conditions, can exhibit properties that are both liquid and solid. LCD TVs work by using liquid crystal molecules arranged between two layers of glass. Under the influence of an electric field, these molecules change their alignment, thereby controlling the passage or blocking of light from the backlight to form an image. Compared to traditional TV cabinets, using a wall mount allows the TV to be hung on the wall, saving indoor space and making the living environment appear more spacious. Therefore, an LCD TV wall mount is necessary.

[0003] Existing LCD TV mounts typically use two mounting plates that are directly hooked to the base plate and secured with screws. This method is rather cumbersome. Furthermore, when using two mounting plates to mount an LCD TV, it's inconvenient to adjust the distance between the plates to accommodate different TV sizes. If the mounting plates are not adjustable, they can only accommodate TVs of a specific size. With the increasing diversity of TV sizes on the market, the applicability of this type of mount will be very limited, failing to meet the needs of most users. Utility Model Content

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 2-4This utility model provides an embodiment of a liquid crystal television mounting bracket, comprising a base 1 and a support plate 10. Support columns 12 are fixedly connected to the upper perimeter of the support plate 10. Mounting plates 13 are fixedly connected to the upper parts of multiple support columns 12. Sliding rods 23 are fixedly connected to both sides of the inner interior of the mounting plate 13. Movable blocks 22 are slidably connected to the outer sides of the two sliding rods 23. Fixing seats 14 are fixedly connected to both sides of the rear of the mounting plate 13. Limit frames 15 are fixedly connected to the upper parts of the two fixing seats 14. Fixing sleeves 16 are slidably connected to both sides of the inner interior of the two limit frames 15. Circular plates 19 are slidably connected to the interior of multiple fixing sleeves 16. Pull rods 18 are fixedly connected to the interior of multiple circular plates 19. Pull plates 17 are fixedly connected to the upper parts of multiple pull rods 18. Multiple pull rods 18 are slidably connected to the interior of the movable blocks 22. Fixing plates 25 are fixedly connected to the front of multiple movable blocks 22. The outer sides of multiple pull rods 18... Each part is fitted with a return spring 20. Multiple pull rods 18 are slidably connected inside the fixed base 14. One end of each return spring 20 is fixedly connected inside the fixed sleeve 16, and the other end of each return spring 20 is fixedly connected to the upper part of the circular plate 19. Each movable block 22 has a handle 24 fixedly connected to its upper part. Multiple handles 24 are slidably connected inside the mounting plate 13. Two fixed plates 25 are slidably connected to the front of the mounting plate 13. Mounting holes 26 are opened around the inside of the two fixed plates 25. Slider 21 are fixedly connected to the outer sides of the multiple fixed sleeves 16. Slide grooves are opened on both sides of the inside of the two limit frames 15. Multiple sliders 21 are slidably connected inside the slide grooves. Insertion holes are opened around the inside of the two fixed bases 14. Multiple pull rods 18 are slidably connected inside the insertion holes. Multiple pull rods 18 are slidably connected inside the fixed sleeves 16. A support plate 11 is fixedly connected to the upper part of the support plate 10.

[0024] The support plate 11 supports the weight of the television, providing a stable platform for users to place the television on the mounting bracket. Then, by pulling the two pull plates 17 upwards, the movement of the pull plates 17 causes the pull rod 18 and the circular plate 19 to rise synchronously. At this time, the rise of the circular plate 19 applies pressure to the return spring 20, causing it to elastically deform. Pushed by the return spring 20, the circular plate 19 continues to rise. The return spring 20 provides elastic force, compressing the circular plate 19 as it rises, thus pushing the circular plate 19 and pull rod 18 back to their original positions. Pulling the pull rod 18, it is pulled out of the fixed base 14 and disengaged from the movable block 22, thereby releasing the fixation of the movable block 22. Next, the user pulls the two handles 24. The movement of the handles 24 causes the movable block 22 to slide along the outside of the slide rod 23, thereby driving the fixed plate 25 forward until the ideal adjustment position is reached. After the adjustment is completed, the user moves the fixing sleeve 16 to guide the slider 21 to slide in the groove within the limiting frame 15. The slider 21 slides in the groove within the limiting frame 15, helping to position the fixing sleeve 16 and maintain the stability of the fixing plate 25. The limiting frame 15 provides a groove to limit the movement range of the slider 21 and the fixing sleeve 16, ensuring the accuracy of the adjustment and the accurate positioning of the fixing sleeve 16. Finally, the user releases the pull plate 17, and the return spring 20 immediately returns to its shape, driving the round plate 19 and the pull rod 18 to reset, so that the round plate 19 is re-embedded in the insertion hole of the fixing seat 14 and returns to the inside of the movable block 22, completing the re-fixing of the movable block 22. In this way, the position adjustment of the fixing plate 25 is completed. Subsequently, the LCD TV is firmly fixed through the mounting hole 26, which is used to firmly fix the LCD TV to the mounting bracket with screws or other fixing devices.

[0025] Reference Figure 1 and Figure 3 The base 1 has positioning plates 3 fixedly connected to both sides of the front part. A motor 4 is fixedly connected to the right side of one positioning plate 3. A rotating shaft 5 is fixedly connected to the output end of the motor 4. A gear 6 is fixedly connected to the outside of the rotating shaft 5. A movable seat 8 is slidably connected inside the base 1. A rack plate 7 is fixedly connected to the front of the movable seat 8. A gear 6 is meshed with the front of the rack plate 7. A support plate 10 is fixedly connected to the upper part of the movable seat 8. A rotating shaft 5 is rotatably connected inside the positioning plate 3 on the other side. Support seats 2 are fixedly connected to both sides of the base 1. Movable plates 9 are slidably connected inside the two support seats 2. Support plates 10 are fixedly connected to the upper part of the two movable plates 9.

[0026] When adjusting the height of the mounting plate 13, the operator only needs to start the motor 4. The output end of the motor 4 then activates the rotating shaft 5, driving it to rotate. As the rotating shaft 5 rotates, the gear 6 also rotates. Through meshing with the rack plate 7, the rack plate 7 moves. The gear 6 is used to convert the form of rotational motion. Driven by the rotating shaft 5, the gear 6 rotates and, through meshing with the rack plate 7, converts the rotational motion into linear motion. The movement of the rack plate 7 further causes the moving seat 8 to move forward, and the movement of the moving seat 8 in turn drives the support plate 10 to move up and down. In this process, the rise or fall of the support plate 10 simultaneously guides the movable plate 9 to slide accordingly inside the support base 2. The movable plate 9 is located inside the support base 2 and can slide along with the rise and fall of the support plate 10. The support base 2 is the basic part of the entire device, providing a sliding track for the movable plate 9.

[0027] Working principle: First, when installing an LCD TV, the user can place the LCD TV on the upper part of the tray 11. Then, pull the two pull plates 17 upwards. When the pull plates 17 move, they drive the pull rod 18 and the circular plate 19 upwards. When the circular plate 19 moves upwards, it compresses the return spring 20. The return spring 20 undergoes elastic deformation under the compression. Under the action of the return spring 20, the circular plate 19 drives the pull rod 18 to move out of the fixed base 14 and out of the movable block 22, releasing the pressure on the movable block 22. After fixing block 22, pull both handles 24. The handles 24 move, causing the movable block 22 to slide outside the slide rod 23. The movement of the movable block 22 causes the front fixing plate 25 to move. After the position of the fixing plate 25 is adjusted, move the fixing sleeve 16 so that the slider 21 slides in the groove inside the limit frame 15. After the fixing sleeve 16 moves to the appropriate position, release the pull plate 17. The return spring 20 drives the circular plate 19 and the pull rod 18 to return to their original positions, so that the circular plate 19 is reinserted into the fixing seat 14. The position of the mounting plate 25 can be adjusted by inserting the movable block 22 into the socket and fixing the movable block 22. Next, the LCD TV is fixed through the mounting hole 26. This allows for convenient adjustment of the position of the mounting plate 25, adapting to LCD TVs of various sizes, improving the versatility and market applicability of the mounting bracket, and simplifying the installation process. When the height of the mounting plate 13 needs to be adjusted, the motor 4 is started. The output end of the motor 4 drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the gear 6 to rotate. When the gear 6 rotates, it drives the meshing rack plate 7 to move. The movement of the rack plate 7 drives the moving seat 8 to move. The movement of the moving seat 8 drives the support plate 10 to move. When the support plate 10 moves up and down, it causes the movable plate 9 to slide inside the support seat 2. The up and down movement of the support plate 10 drives the mounting plate 13 to move up and down, which allows for convenient adjustment of the height of the mounting plate 13. The hanging height of the TV can be adjusted according to height and viewing habits to ensure that the TV is always in the best viewing position.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
