Description
Technical Field
[0001] This utility model relates to the field of liquid crystal display technology, specifically to an adjustable rotating device for a liquid crystal display. Background Technology
[0002] Liquid crystal displays (LCDs) are flat-panel display technologies that regulate light transmission by controlling the deflection of liquid crystal molecules using voltage. Their core material, liquid crystal, possesses properties between a solid and a liquid state. Light transmission is controlled by altering the molecular arrangement through an electric field, and combined with red, green, and blue color filters, color imaging is achieved. An adjustable rotating device for an LCD screen is a mechanical structure used to adjust the angle of an LCD screen. It achieves multi-dimensional rotation of the screen through physical or electric means to meet viewing needs in different scenarios.
[0003] Conventional adjustable rotating devices for LCD screens often employ fixed brackets or single-axis rotation designs, which suffer from limited adjustment range and insufficient stability. For example, traditional single-axis rotating brackets can only achieve unidirectional rotation in the horizontal direction and cannot meet the needs of vertical angle adjustment; while some simple brackets are prone to wobbling during adjustment, affecting the user experience. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable rotating device for a liquid crystal display screen to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable rotating device for a liquid crystal display screen, comprising a first adjusting component and a second adjusting component. A combined frame component is connected and installed on the top of the first adjusting component, and the second adjusting component is connected and installed on the top of the combined frame component. An assembly plate is connected and installed on the end of the second adjusting component away from the combined frame component. The second adjusting component includes a double-segment damping hinge, a fastening bolt, a first ratchet rotating seat, and a second ratchet rotating seat. Fastening bolts are installed at the horizontal threads at both ends of the middle shaft of the double-segment damping hinge. The first ratchet rotating seat is connected and installed on the end of the double-segment damping hinge near the assembly plate, and the second ratchet rotating seat is connected and installed on the end of the double-segment damping hinge away from the first ratchet rotating seat.
[0006] Furthermore, the first adjusting component includes a base, a support column, an adjusting stud, and a mating seat. The support column is vertically arranged at the top center of the base, and the adjusting stud is vertically threaded inside the support column. The mating seat is provided at the top of the adjusting stud.
[0007] Furthermore, the base has holes at each of the four opposite corners for bolt installation, and the base and the support column are connected by welding.
[0008] Furthermore, the combined structural components include a first stabilizer, a second stabilizer, and a docking groove. The second stabilizer is provided at the bottom of the first stabilizer, and the docking groove is provided in the middle of both the first stabilizer and the second stabilizer.
[0009] Furthermore, both ends of the first and second stabilizers are symmetrically provided with two sets of holes for bolt installation, and the structures of the first and second stabilizers are identical.
[0010] Furthermore, the top surface structure of the docking seat matches the inner surface structure of the docking groove, and the bottom four opposite corners of the second stabilizer and the four opposite corners of the first stabilizer are provided with holes for bolt installation, and the bottom four opposite corners of the second ratchet rotary seat and the four opposite corners of the first stabilizer are provided with holes for bolt installation.
[0011] Furthermore, the assembly plate includes a plate body, a protective pad, and combination holes. The protective pad is attached to the side of the plate body away from the second adjusting structural component, and multiple sets of combination holes of various specifications are opened on the surface of the plate body.
[0012] Furthermore, the four diagonal points of the first ratchet rotary seat are provided with holes for bolt installation at the connection points with the middle of the plate, and the plate is made of high-strength material.
[0013] This utility model provides an adjustable rotating device for a liquid crystal display screen, which has the following advantages: 1. This utility model, by incorporating a second adjusting structure, significantly enhances the overall rotational flexibility and stability of the device. The dual-stage damping hinge, as a core component, achieves precise adjustment within a certain angle range in the vertical direction through fastening bolts at both ends. The combined use of the first and second ratchet swivel seats, along with the structural adjustment of the dual-stage damping hinge, allows the assembly plate to rotate at multiple angles in both the vertical and horizontal directions smoothly and without jamming. This effectively improves the adaptability of the LCD screen in different usage scenarios. Furthermore, the assembly plate design fully considers the installation and protection needs of the LCD screen. Multiple sets of multi-specification combination holes on the plate can accommodate LCD screens of different sizes and interface types. The protective pads effectively prevent damage to the screen due to collisions during installation or use, extending the screen's lifespan.
[0014] 2. In this utility model, the design of the first adjusting component fully considers the height adjustment requirements of the device. The base serves as a stable foundation, and vertical height adjustment is achieved through adjusting studs inside the support column. The precise docking of the docking seat and the combined structural components ensures the structural stability of the entire device during adjustment, avoiding swaying or tilting caused by height changes. The combined structural components employ a superimposed design of a first and a second stabilizing frame, which not only enhances the overall structural strength of the device but also allows for quick installation and disassembly of the first and second adjusting components via the intermediate docking groove. This modular design makes maintenance and upgrades of the device more convenient and efficient. Furthermore, the modular structure of the first adjustment component, the combined frame component, the second adjustment component, and the assembly plate allows for selective combination and use as needed. In practical applications, users can flexibly select and assemble each component based on factors such as the size and weight of the LCD screen, the required adjustment angle, and the range of installation structures, thereby obtaining an adjustable rotating device that best suits their usage requirements. Moreover, this modular design means that if a component is damaged or requires a functional upgrade during later use, only the corresponding component needs to be replaced or upgraded, without replacing the entire device, thus reducing usage costs and maintenance difficulty.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0018] like Figures 1 to 5 As shown, an adjustable rotating device for a liquid crystal display screen includes a first adjusting component 1 and a second adjusting structural component 3. A combined frame component 2 is connected and installed on the top of the first adjusting component 1. The second adjusting structural component 3 is connected and installed on the top of the combined frame component 2, and an assembly plate 4 is connected and installed on the end of the second adjusting structural component 3 away from the combined frame component 2. The second adjusting structural component 3 includes a double-stage damping hinge 301, a fastening bolt 302, a first ratchet swivel seat 303, and a second ratchet swivel seat 304. Fastening bolts 302 are installed at the horizontal threads at both ends of the central axis of the 301. A first ratchet swivel seat 303 is connected to the end of the double-stage damping hinge 301 closest to the assembly plate 4, and a second ratchet swivel seat 304 is connected to the end of the double-stage damping hinge 301 furthest from the first ratchet swivel seat 303. The assembly plate 4 includes a plate body 401, a protective pad 402, and a combination hole 403. The protective pad 402 is affixed to the surface of the plate body 401 furthest from the second adjusting structural component 3. The surface of plate 401 has multiple sets of multi-specification combination holes 403. The four diagonal corners of the first ratchet swivel base 303 are all provided with holes for bolt installation at the connection points with the middle of the plate 401. The plate 401 is made of high-strength material. The damping characteristics of the double-stage damping hinge 301 are utilized to achieve stepless speed change during adjustment, ensuring the smoothness and precision of the rotation. This design not only improves the user experience but also effectively avoids the problem of screen shaking or displacement caused by sudden rotation. At the same time, the fastening bolt 302 ensures that the entire device remains stable after being adjusted to a suitable angle, preventing accidental rotation due to external forces. The design of the first ratchet swivel base 303 and the second ratchet swivel base 304 further enhances the rotational flexibility and stability of the device. They can provide rotational support in the horizontal and vertical directions respectively, allowing the mounting plate 4 to be adjusted at multiple angles in three-dimensional space to meet the viewing needs of different usage scenarios.
[0019] like Figures 1 to 5As shown, the first adjusting component 1 includes a base 101, a support column 102, an adjusting stud 103, and a mating seat 104. The support column 102 is vertically arranged at the top center of the base 101, and the adjusting stud 103 is vertically threaded inside the support column 102. The mating seat 104 is located at the top of the adjusting stud 103. Holes for bolt installation are provided at the four opposite corners of the base 101. The base 101 and the support column 102 are connected by welding. Component 2 includes a first stabilizer 201, a second stabilizer 202, and a mating groove 203. The second stabilizer 202 is located at the bottom of the first stabilizer 201, and both the first stabilizer 201 and the second stabilizer 202 have mating grooves 203 in the middle. Both ends of the first stabilizer 201 and the second stabilizer 202 have two sets of symmetrical holes for bolt installation. The first stabilizer 201 and the second stabilizer 202 have identical structures. The mating seat 104 is used for mating. The top surface structure of the base 104 matches the inner surface structure of the docking groove 203. Holes for bolt installation are provided at the four opposite corners of the bottom of the second stabilizer 202 and the four opposite corners of the first stabilizer 201. Similarly, holes for bolt installation are provided at the four opposite corners of the bottom of the second ratchet rotary base 304 and the four opposite corners of the first stabilizer 201. The robust design of the base 101 and the bolt holes at the four opposite corners ensure a secure connection between the device and the mounting surface, effectively preventing shaking or displacement during use. The welded connection between the support column 102 and the base 101 further enhances the overall structural strength, enabling the device to withstand greater external forces without deformation or damage. The adjustable stud 103 provides users with flexible height adjustment; by rotating the adjustable stud 103, the vertical height of the device can be easily adjusted to meet viewing needs in different usage scenarios.
[0020] In summary, as Figures 1 to 5 As shown, the adjustable rotating device for the LCD screen can be used by first selecting a suitable installation position based on the actual usage scenario and factors such as the size and weight of the LCD screen. Then, using the bolt mounting holes at the four opposite corners of the base 101, the device can be securely installed on the desktop or other supporting surface to ensure that the device will not shake or shift during use. Next, select the appropriate combination hole 403 according to the interface type and size of the LCD screen, and install the screen on the mounting plate 4 with bolts or other fasteners. The protective pad 402 can effectively prevent the screen from being damaged by collision during installation or use. Then, according to the viewing requirements, the overall height of the device is adjusted by rotating the adjusting stud 103 to make the display screen in the best viewing position. The precise docking of the docking seat 104 and the combined frame component 2 ensures the structural stability of the device during the adjustment process. Finally, the angle of the display screen is adjusted as needed. The damping characteristics of the dual-stage damping hinge 301 are used to achieve stepless speed regulation, ensuring the smoothness and precision of the rotation. At the same time, the fastening bolt 302 ensures that the device remains stable after being adjusted to a suitable angle. The design of the first ratchet swivel seat 303 and the second ratchet swivel seat 304 further enhances the rotational flexibility and stability of the device, allowing the display screen to be adjusted at multiple angles in three-dimensional space to meet the viewing needs of different usage scenarios.
