Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display technology, specifically to a liquid crystal display backplate. Background Technology

[0002] Liquid crystal is a substance that exists between a solid and a liquid state, with its molecules arranged in a regular pattern. Liquid crystal displays (LCDs) control the orientation of liquid crystal molecules using an electric field, thereby regulating the amount of light transmitted. LCDs are a flat-panel display technology based on the electro-optic effect of liquid crystals, widely used in devices such as mobile phones, televisions, computers, and tablets. The backplate is the outer casing behind the LCD, used to support and protect its internal structure.

[0003] The mounting mechanism on the back panel is generally used to hang the LCD screen directly on the wall by insertion. Compared with the traditional bolt fixing method, it has the characteristics of quick installation and disassembly. However, the distance between the two pins of the existing mounting mechanism cannot be adjusted, and it can only be installed on the same bracket on the wall. It is troublesome to replace different models of LCD screens, and the adaptability is poor. Therefore, a new LCD screen back panel is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a backplate for a liquid crystal display screen that can solve the problem of poor adaptability of traditional backplate mounting mechanisms.

[0005] To achieve the above objectives, a back panel for a liquid crystal display screen is provided, including a back panel, a mounting plate fixedly connected to the center of the front of the back panel, a connecting bearing fixedly connected to the center of the interior of the mounting plate, threaded grooves symmetrically opened on the surface of the mounting plate, and a support bearing fixedly connected to the interior of the two threaded grooves on the side away from the connecting bearing.

[0006] A first threaded rod is fixedly connected between the inner shaft of the support bearing on the right and the inner shaft of the connecting bearing. A second threaded rod is fixedly connected between the other side of the inner shaft of the connecting bearing and the inner shaft of the support bearing on the left. Threaded blocks are threaded onto the surfaces of both the first and second threaded rods. An adjustment knob is installed inside the left side of the mounting plate.

[0007] According to the aforementioned LCD screen backplate, the surface of the threaded block is slidably connected to the interior of the threaded groove, the adjustment knob is fixedly connected to the other side of the inner shaft of the left support bearing via a connecting rod, and the surface thread directions of the first threaded rod and the second threaded rod are opposite to each other.

[0008] According to the aforementioned LCD screen backplate, the upper and lower ends of the two threaded grooves are provided with sliding grooves, and sliders are slidably connected inside the sliding grooves. The two sliders are fixedly connected to the threaded block.

[0009] According to the aforementioned liquid crystal display backplate, a U-shaped mounting pin is installed on the surface of the threaded block.

[0010] According to the aforementioned LCD screen back panel, multiple heat dissipation slots are symmetrically located on the front side of the back panel.

[0011] According to the aforementioned LCD screen back panel, dustproof mesh is installed inside each of the plurality of heat dissipation slots.

[0012] According to the aforementioned LCD screen back panel, mounting threaded holes are provided inside the four corners of the reverse side of the back panel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This LCD screen backplate features an adjustment knob, a first threaded rod, and a second threaded rod. Rotating the adjustment knob indirectly drives the first and second threaded rods to rotate, thereby moving the corresponding threaded blocks. This causes the two U-shaped mounting pins to move closer to and further apart, changing the distance between the pins in the backplate mounting mechanism. This allows different models of LCD screens to be mounted on the same bracket on the wall, making it practical.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a liquid crystal display screen back panel, including a back panel 1, a mounting plate 2 fixedly connected to the center of the front of the back panel 1, a connecting bearing 3 fixedly connected to the center of the interior of the mounting plate 2, threaded grooves 4 symmetrically opened on the surface of the mounting plate 2, and a support bearing 5 fixedly connected to the side of the two threaded grooves 4 away from the connecting bearing 3.

[0024] A first threaded rod 6 is fixedly connected between the inner shaft of the right support bearing 5 and the inner shaft of the connecting bearing 3. A second threaded rod 7 is fixedly connected between the other side of the inner shaft of the connecting bearing 3 and the inner shaft of the left support bearing 5. Threaded blocks 8 are threaded onto the surfaces of both the first threaded rod 6 and the second threaded rod 7. An adjustment knob 9 is installed inside the left side of the mounting plate 2. By setting the adjustment knob 9, the first threaded rod 6, and the second threaded rod 7, rotating the adjustment knob 9 indirectly drives the first threaded rod 6 and the second threaded rod 7 to rotate, thereby driving the corresponding threaded blocks 8 to move. This causes the two U-shaped mounting pins 12 to move closer and further apart, changing the distance between the pins of the backplate mounting mechanism. This allows different models of LCD screens to be mounted on the same bracket on the wall, making it practical.

[0025] The surface of the threaded block 8 is slidably connected to the inside of the threaded groove 4. The adjusting knob 9 is fixedly connected to the other side of the inner shaft of the left support bearing 5 via the connecting rod. The surface thread directions of the first threaded rod 6 and the second threaded rod 7 are opposite to each other.

[0026] Both the upper and lower ends of the two threaded grooves 4 are provided with sliding grooves 10. Sliding sliders 11 are slidably connected inside the sliding grooves 10. The two sliding sliders 11 are fixedly connected to the threaded block 8. By setting the sliding sliders 11 to slide inside the sliding grooves 10, the movement of the threaded block 8 is restricted, preventing the threaded block 8 from wobbling up and down during movement, thus improving the stability of the U-shaped mounting pin 12 when it moves. At the same time, due to the fixation between the sliding sliders 11 and the threaded block 8, the threaded block 8 is prevented from being pushed out of the threaded grooves 4 during the installation of the LCD screen, thus improving the stability of the LCD screen when it is suspended on the wall.

[0027] The surface of the threaded block 8 is equipped with a U-shaped mounting pin 12. By inserting the U-shaped mounting pin 12 into the wall bracket slot, the LCD screen can be installed on the wall. Compared with the bolt installation method, it has the characteristics of quick disassembly and installation, which facilitates the replacement and maintenance of the LCD screen.

[0028] Multiple heat dissipation slots 13 are symmetrically provided on the front of the back panel 1. By setting the heat dissipation slots 13, the internal heat can be dissipated through the air, which can effectively reduce the heat generated when the LCD screen is working, lower the internal temperature of the back panel 1, and prevent heat accumulation from damaging the LCD screen.

[0029] Each of the multiple heat dissipation slots 13 is equipped with a dustproof mesh 14. By setting the dustproof mesh 14, dust in the outside air of the back panel 1 is intercepted, preventing dust from entering the interior of the back panel 1 through the heat dissipation slots 13, thus avoiding problems such as short circuits and heat accumulation.

[0030] The back panel 1 has four mounting threaded holes 15 inside the four corners on the reverse side. The mounting threaded holes 15 are used to assemble the back panel 1 with the front panel. The back panel 1 and the front panel can be fixed together by the connection between the bolts and the mounting threaded holes 15. The core components of the LCD screen are sandwiched in between, protecting and supporting the core components from interference from the external environment.

[0031] Working Principle: When using the LCD screen, first turn the adjustment knob 9. The adjustment knob 9 indirectly drives the first threaded rod 6 to rotate through the connecting rod and the left support bearing 5. Since the first threaded rod 6 and the second threaded rod 7 are connected to both sides of the inner shaft of the connecting bearing 3, the first threaded rod 6 indirectly drives the second threaded rod 7 to rotate through the connecting bearing 3. Since the surface threads of the first threaded rod 6 and the second threaded rod 7 are opposite to each other, and the first threaded rod 6 and the second threaded rod 7 are both connected to the internal threads of the corresponding threaded block 8, the first threaded rod 6 and the second threaded rod 7 drive the corresponding threaded block 8 to move closer and further apart, causing the two U-shaped mounting pins 12 to move closer and further apart. Then, adjust the appropriate distance according to the position of the wall bracket slot. Next, align the plugs of the two U-shaped mounting pins 12 with the corresponding wall bracket slots. Then, slowly lower the LCD screen until the plugs of the U-shaped mounting pins 12 are fully inserted into the wall bracket slots. Release the LCD screen, and the LCD screen is installed on the wall.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
