Technical Field

[0001] The utility model relates to the technical field of liquid crystal display screens, in particular to a liquid crystal display screen with adjustable viewing angle. Background Art

[0002] Liquid crystal display (LCD) is a type of display used in digital clocks and many portable computers. Currently, all technological information products are developing towards the goal of being light, thin, short and small. Under the premise of being easy to carry and transport, traditional display methods such as CRT image tube displays and LED display panels are restricted by factors such as large size or huge power consumption, and cannot meet the actual needs of users. The development of LCD display technology just fits the current trend of information products. Whether it is right-angle display, low power consumption, small size, or zero radiation, it can allow users to enjoy the best visual environment.

[0003] The widespread use of liquid crystal displays has led to more and more extensive requirements for liquid crystal displays, such as changing the viewing angle. The existing viewing angle adjustable liquid crystal display technology mainly uses a complex and large mechanical structure to achieve the change of viewing angle. Therefore, the structure is complex and the stability is poor. There is an urgent need for a liquid crystal display with adjustable viewing angle. Utility Model Content

[0004] The purpose of the utility model is to provide a liquid crystal display screen with adjustable viewing angle. The utility model is provided with a third fixed block, a rotation damper, a second fixed block, a fourth slot, a limit block, a cross bar and a third slot, and the second fixed block is allowed to perform controlled rotational movement through the rotation dampers at the upper and lower ends of the third fixed block. This design provides a smooth and uniform adjustment process, so that the user can easily adjust the position and angle of the cross bar. The limit block is arranged inside the fourth slot and matches the outer ring size of the second fixed block, so that the position of the cross bar can be accurately controlled to prevent it from excessive movement or accidental disengagement, thereby ensuring the stability of the cross bar during use. The third slot inside the cross bar provides an installation point for other components (such as cable management or additional accessories), thereby increasing the functionality and adaptability of the entire supporting structure, so that it can meet the personalized needs of more types of equipment and users. The design of the rotation damper helps to prevent rapid or accidental rotation, thereby protecting the supported equipment (such as a display) from damage and ensuring the safety of the user.

[0005] To achieve the above-mentioned purpose, a liquid crystal display screen with adjustable viewing angle is provided, comprising: a steering assembly and a support rod assembly, the steering assembly comprising a fourth slot, a second fixed block, a rotary damper, a third fixed block, a limit block, a fourth fixed block, a positioning column, a second nut, a second slot, a rotating bolt, a first nut, a first fixed block, a fixed plate, and a fixed column, the support rod assembly comprising a third slot, a cross bar, a vertical bar, a base and a first slot, the vertical bar having a first slot therein, the front side of the vertical bar being fixedly connected to a third fixed block, the upper and lower ends of the third fixed block being fixedly connected to a rotary damper, the inner ring of the rotary damper being rotatably connected to the second fixed block, the outer ring of the second fixed block being penetrated by a fourth slot, a limit block being arranged inside the fourth slot, the outer ring of the second fixed block being fixedly connected to a cross bar, and the cross bar having a third slot therein;

[0006] The bottom end of the vertical rod is fixedly connected to a base, the bottom end of the base is fixedly connected to a fourth fixing block, the bottom end of the fourth fixing block is fixedly connected to a positioning column, and the outer ring of the positioning column is rotatably connected to a second nut;

[0007] Through the above technical scheme, the first slot inside the vertical rod is used to install other components, the third fixed block and the rotation damper are used to fix the second fixed block and control its rotation speed through damping, the outer ring of the second fixed block passes through the fourth slot, and the limit block is arranged inside the fourth slot to limit the movement range of the second fixed block, the cross bar is fixedly connected to the outer ring of the second fixed block, and the third slot inside it is used to install other components, the base and the fourth fixed block are used to stabilize the entire structure, the positioning column and the second nut are used to adjust and fix the position of the positioning column, and the structure provides a flexible adjustment method through the adjustable rotation damper and the limit block, so that the support device can adapt to displays or other equipment of different sizes and weights, and at the same time, by turning the bolt and the threaded connection of the first nut, the position of the fixed plate and the display can be easily adjusted to achieve quick installation and disassembly, and in addition, the number of fixing columns is four, which provides stable support and ensures the stability and safety of the display.

[0008] Furthermore, a second slot is formed on the front side of the crossbar, and rotating bolts are passed through the left and right sides of the second slot;

[0009] Through the above technical solution, the second slot on the front side of the cross bar is designed to install a rotating bolt, thereby realizing the rotation and adjustment function of the cross bar. The rotating bolt runs through the left and right sides of the second slot, so that the cross bar can rotate around the axis of the rotating bolt, thereby adjusting the angle and position of the cross bar to meet the needs of different heights and angles. This design allows the user to easily adjust the position and angle of the cross bar as needed, thereby improving the flexibility and adaptability of the support device. The user can adjust the position of the cross bar according to the viewing angle of the display or the requirements of the spatial layout to achieve the best use effect. In addition, the design of the rotating bolt also makes the installation and disassembly process easier, and the user can quickly adjust the support device without complicated operations or tools.

[0010] Further, the outer ring of the rotating bolt is threadedly connected with a first nut, and the outer ring of the rotating bolt is rotatably connected with a first fixing block;

[0011] Through the above technical solution, the outer ring of the rotating bolt is threadedly connected with the first nut. Such a design allows the user to fix or release the rotation of the rotating bolt by tightening or loosening the first nut. The first fixed block is rotatably connected through the outer ring of the rotating bolt and can slide axially along the outer ring of the rotating bolt, thereby adjusting the distance and position between the fixed plate (connected to the first fixed block) and the cross bar. This design provides a simple and efficient adjustment mechanism, so that the fixed plate can be easily moved along the cross bar to accommodate displays or devices of different sizes. The user can quickly adjust the position of the fixed plate according to actual needs to achieve optimal support and viewing angle.

[0012] Furthermore, a fixing plate is fixedly connected to the front side of the first fixing block, the front side of the fixing plate abuts against the display, and fixing columns are threadedly connected to the four corners of the fixing plate;

[0013] Through the above technical solution, the front side of the first fixed block is fixedly connected to the fixing plate. This design allows the fixing plate to form a stable connection with the first fixed block. The front side of the fixing plate is in contact with the monitor, which means that the fixing plate can support the weight of the monitor to keep it stable. The four corners of the fixing plate are threadedly connected with fixing columns. Such a design can provide additional support for the fixing plate to ensure that the monitor can be firmly fixed in all directions. A significant beneficial effect of this design is that it provides a stable and adjustable support system that can adapt to monitors of different sizes and weights. Through the threaded fixing columns, the user can adjust the position of the fixing columns according to the specific size and shape of the monitor to achieve the best support effect.

[0014] Further, the number of the rotary damper and the third fixing block is two;

[0015] Through the above technical solution, the number of rotational dampers and third fixed blocks is two. This design usually means that a rotational damper and a third fixed block are installed on each side of the supporting structure. Such a configuration can provide symmetrical support and adjustment functions, so that the entire structure is more stable and balanced during the adjustment process. The rotational damper can control the rotation speed to prevent rapid or accidental rotation, and the third fixed block serves as a fixing point for the rotational damper to ensure the stability of the structure. The configuration of two rotational dampers and the third fixed block has a significant beneficial effect of enhancing the balance and stability of the entire supporting structure. The symmetrical design helps to disperse the force and reduce the tilt or shaking caused by uneven force, thereby improving the safety of the display or other equipment. In addition, the symmetrical rotation damper can provide a more uniform adjustment resistance, so that the user can experience a smoother and more consistent experience when adjusting the position of the cross bar or fixed plate.

[0016] Furthermore, the number of the fourth slots is several, and the limit block is in an "L" shape and matches the size of the fourth slot;

[0017] Through the above technical solution, the number of the fourth slots is several, which means that there are multiple slots on the outer ring of the second fixed block, and these slots can be used as interfaces for installing or adjusting different components. The limit block is "L" shaped. This design enables the limit block to provide multi-directional support and restriction in the fourth slot. The size of the limit block matches that of the fourth slot to ensure that the limit block can be correctly installed in the slot and will not loosen or fall off. One beneficial effect of this design is that it improves the flexibility and accuracy of adjustment. By arranging several fourth slots on the second fixed block, multiple adjustment positions can be provided for the cross bar or components related thereto to adapt to the needs of different users and different usage scenarios. At the same time, the "L"-shaped limit block can provide support in different directions, increase the stability of the structure, and prevent the second fixed block from excessive movement or accidental disengagement during the adjustment process. The limit block and the fourth slot with matching sizes ensure the tightness and reliability of the assembly, thereby improving the durability and service life of the entire support device.

[0018] Furthermore, the number of the fixing columns is four;

[0019] Through the above technical solution, the number of the fixing columns is four, which means that there is a fixing column at each of the four corners of the fixing plate. Such a configuration provides uniform support for the fixing plate, ensuring the stability and load-bearing capacity of the fixing plate. The fixing columns are connected to the fixing plate by threads, allowing the user to adjust the height of the fixing columns as needed to adapt to monitors or other devices of different sizes. A major beneficial effect of this design is that the overall stability and load-bearing distribution of the fixing plate are improved. The four fixing columns are evenly distributed at the four corners of the fixing plate, which helps to disperse the weight of the display and reduce local pressure on the fixing plate, thereby reducing the risk of deformation or damage.

[0020] Further, the fourth slotted column is square;

[0021] Through the above technical solution, the fourth slotted column is square, which means that the slot on the second fixed block has a square cross-sectional shape. This design can provide a stable support surface for the limit block, and also facilitates the positioning and fixing of the limit block in the slot. The square column shape helps to ensure that the limit block remains stable in the slot and reduces sliding or rotation caused by shape mismatch. A significant beneficial effect is that the stability and reliability of the structure are improved. The square column shape provides the limit block with a consistent contact area and support force, which helps to keep it stable when adjusting or fixing the position of the cross bar. In addition, the square column design simplifies the manufacturing and assembly process because the right-angle edges are easier to process and measure.

[0022] The above scheme has the following beneficial effects:

[0023] 1. The utility model is provided with a third fixed block, a rotation damper, a second fixed block, a fourth slot, a limit block, a cross bar and a third slot, and the second fixed block is allowed to perform a controlled rotational movement through the rotation dampers at the upper and lower ends of the third fixed block. This design provides a smooth and uniform adjustment process, so that the user can easily adjust the position and angle of the cross bar. The limit block is arranged inside the fourth slot and matches the outer ring size of the second fixed block, so that the position of the cross bar can be accurately controlled to prevent it from excessive movement or accidental disengagement, thereby ensuring the stability of the cross bar during use. The third slot inside the cross bar provides an installation point for other components (such as cable management or additional accessories), which increases the functionality and adaptability of the entire support structure, so that it can meet the personalized needs of more types of equipment and users. The design of the rotation damper helps to prevent rapid or accidental rotation, thereby protecting the supported equipment (such as a display) from damage and ensuring the safety of the user.

[0024] 2. The utility model is provided with a fourth fixing block, a positioning column and a second nut, and the bottom end of the vertical rod is connected to the fourth fixing block through the base, and then is rotatably connected to the second nut through the positioning column, thereby forming a multi-level fixing structure, which greatly increases the stability of the entire support system and reduces the risk of overturning due to external force. The rotational connection between the outer ring of the positioning column and the second nut allows fine-tuning of the vertical position of the vertical rod to adapt to installation environments or equipment requirements at different heights to ensure the horizontal and vertical alignment of the equipment. The bottom end of the base is fixedly connected with the fourth fixing block. Such a design simplifies the installation process. The user only needs to place the base on a stable surface to quickly complete the construction of the support system. Through the rotation adjustment of the second nut, it can adapt to installation surfaces of different thicknesses or sizes, such as walls, countertops or other supporting structures, thereby increasing the versatility and applicability of the product.
