Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to an adjustable-angle LCD display screen. Background Technology

[0002] An LCD display is a display device that utilizes the optical properties of liquid crystal materials. Its core lies in the liquid crystal layer sandwiched between two parallel glass plates. When no electricity is applied, these liquid crystal molecules are arranged in a specific way to block light from passing through. When different voltages are applied, their rotation angle can be precisely controlled, thereby changing their light transmittance. In conjunction with a backlight and front and rear polarizing filters, this voltage control can precisely adjust the brightness of each pixel's red, green, and blue sub-pixels, combining various colors and brightness levels to ultimately display images on the screen.

[0003] However, existing LCD displays typically have adjustable-angle stands, but these stands are difficult to disassemble after installation, and the base is space-consuming and inconvenient to carry when moving or taking the display to different locations. Therefore, those skilled in the art have provided an adjustable-angle LCD display to solve the problems mentioned in the background section. Utility Model Content

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.

[0033] Reference Figure 1-4 The present invention provides an adjustable angle LCD display screen, including an LCD display screen body 1, a mounting bracket 2 movably inserted into the bottom of the LCD display screen body 1, an angle adjustment mechanism 3 provided on the outside of the mounting bracket 2, a fixing base 4 fixed at the bottom of the angle adjustment mechanism 3, a power cord 5 connected to the outside of the LCD display screen body 1, and a line protection mechanism 6 provided on the outside of the LCD display screen body 1.

[0034] The angle adjustment mechanism 3 includes a fixed frame 31. A rotating connecting column 32 is installed on one side of the fixed frame 31 and extends through the other side. An anti-slip pad 33 is fixed on the outer side of the rotating connecting column 32. A connecting bracket 34 is fixed on the outer side of the mounting frame 2. The connecting bracket 34 has a mounting hole 37 inside. A fixing threaded rod 35 is fixed on the outer side of the LCD display body 1. A metal nut 36 is threaded onto the outer side of the fixing threaded rod 35. A groove is provided at the bottom of the LCD display body 1. The size of the groove is adapted to the size of the mounting frame 2. When the mounting frame 2 is movably inserted into the LCD display body 1, positioning can be quickly completed during assembly. A groove is provided inside the connecting bracket 34. The size of the groove is adapted to the size of the fixing threaded rod 35. The connecting bracket 34 can be movably sleeved on the outer side of the fixing threaded rod 35. A groove is provided at the top of the connecting bracket 34. The size of the groove is adapted to the size of the LCD display body 1. The fixed frame 31 and the fixed base 4 are fixedly connected. The connecting bracket 34 and the LCD display body 1 are fixedly connected by bolts.

[0035] The line protection mechanism 6 includes a lower fixing sleeve 61, a support connecting pad 62 fixed on the outer side of the lower fixing sleeve 61, a first semi-threaded post 63 provided on the top of the support connecting pad 62, an upper fixing sleeve 64 hinged to the top of the lower fixing sleeve 61, a limit sleeve 65 fixed on the outer side of the upper fixing sleeve 64, a second semi-threaded post 66 fixed on the top of the limit sleeve 65, a washer 67 movably sleeved on the outer side of the second semi-threaded post 66 and the first semi-threaded post 63, a connecting nut 68 threadedly connected to the outer side of the second semi-threaded post 66 and the first semi-threaded post 63, and a protective sleeve 69 fixed on the inner wall of both the lower fixing sleeve 61 and the upper fixing sleeve 64, the inner wall of the protective sleeve 69 being in contact with the power cord 5.

[0036] Working principle: When the LCD display body 1 and the mounting bracket 2 are connected, the LCD display body 1 is placed on top of the connecting bracket 34, and one end of the mounting bracket 2 is movably inserted into the interior of the LCD display body 1. At this time, the mounting hole 37 is movably sleeved on the outside of the fixing threaded rod 35. Then, the metal nut 36 is threadedly connected to the fixing threaded rod 35, thus facilitating quick positioning between the LCD display body 1 and the mounting bracket 2, which is beneficial for positioning during assembly and fixing. Then, the bolt is threadedly connected to the LCD display body 1 through the mounting hole 37, facilitating the fixing between the connecting bracket 34 and the LCD display body 1. Subsequently, the LCD display body 1 can be rotated to drive the rotating connecting column 32 on the outside of the mounting bracket 2 to rotate, achieving the purpose of angle adjustment. Moreover, the LCD display body 1 and the mounting bracket 2 are easy to disassemble. When moving or taking it to different places, the LC can be easily disassembled after removing the base. The LCD display body 1 is lighter and easier to put into a bag or box, making it easy to carry and store. With the circuit protection mechanism 6, after the power cord 5 is connected to the LCD display body 1, the upper fixing sleeve 64 on the top of the lower fixing sleeve 61 can be moved so that the limiting sleeve 65 on the outside of the upper fixing sleeve 64 can be movably fitted onto the outside of the first half-threaded post 63. At this time, the corresponding surfaces of the second half-threaded post 66 and the first half-threaded post 63 on the top of the limiting sleeve 65 are in contact. Then, the gasket 67 is movably fitted onto the outside of the second half-threaded post 66 and the first half-threaded post 63, and the connecting nut 68 is threadedly connected to the second half-threaded post 66 and the first half-threaded post 63, which conveniently completes the fixation between the upper fixing sleeve 64 and the lower fixing sleeve 61. The protective sleeve 69 on the inner wall of the upper fixing sleeve 64 and the lower fixing sleeve 61 is in contact with the power cord 5. The protective sleeve 69 reinforces the connection part of the power cord 5, preventing the connection part of the power cord 5 from becoming loose due to accidental pulling.
