Description

Technical Field

[0001] This application relates to the field of monitor bracket technology, and more particularly to a screen adjustment device for computers. Background Technology

[0002] Computer screen adjustment devices are hardware used to adjust the position, angle, display parameters, or physical state of a monitor. Their core function is to optimize the user experience and protect the user's health. By adjusting the screen height and angle, the height, front-to-back distance, tilt angle, and rotation direction of the screen can be adjusted manually or electrically to make the line of sight level with or slightly lower than the center of the screen, reducing pressure on the cervical and lumbar spine and preventing strain from prolonged sitting.

[0003] Currently, Chinese utility model patent application CN222577752U, published on March 7, 2025, provides a computer stand that facilitates lateral adjustment. It includes a fixed base plate, a limiting plate connected to the end face of the fixed base plate, a fixed slider on the end face of the limiting plate, and corresponding fixing teeth on the end face of the limiting plate that contacts the fixed slider. A fixing block is connected to the side wall of the limiting plate and the fixed slider. This utility model, by incorporating a limiting plate, a fixed slider, fixing teeth, and a fixing block in a computer stand that facilitates lateral adjustment, utilizes the interaction between these components to facilitate computer screen adjustment. This design allows for quick adjustment of the computer screen position according to user needs, thus solving the problem of inconvenient computer screen position adjustment.

[0004] The lateral adjustment computer stands in related technologies have significant functional limitations. They can only allow the computer to move horizontally, offering a single adjustment dimension. Their adjustable range is strictly limited to this fixed horizontal dimension. They cannot adjust the height according to the user's sitting or standing posture, nor can they tilt the screen for different usage scenarios such as typing, watching movies, or drawing, resulting in a severe lack of adjustment flexibility. This design completely fails to cover the diverse needs of users in actual use. For example, when a user wants to stand up after sitting for a long time, the stand cannot be raised to match the eye level when standing; when a user wants to look down at the screen to reduce neck strain, the stand cannot provide an angle tilt function. Ultimately, it fails to meet the core demand for a comfortable user experience in different postures.

[0005] Therefore, it is necessary to propose a computer screen adjustment device to solve the above problems. Utility Model Content

[0006] This application provides a screen adjustment device for computers, which aims to improve the technical problem that computer stands in the related technology have a limited adjustment range, which cannot cover the diverse needs of users in actual use and ultimately fails to meet the core demand of users for a comfortable user experience in different postures.

[0007] This application provides a computer screen adjustment device, including a base and a display screen support plate, and also includes...

[0008] The first guide cylinder is mounted on the base, and the vertical adjusting rod is movably mounted inside the first guide cylinder, which is used to drive the display screen support plate to move axially.

[0009] The second guide cylinder is mounted on the output shaft of the vertical adjusting rod, and the longitudinal adjusting rod is movably mounted inside the second guide cylinder, which is used to drive the display screen support plate to move longitudinally.

[0010] The third guide cylinder is fixedly mounted on the longitudinal adjusting rod. The central axes of the second and third guide cylinders form an angle. An angle adjusting rod is movably mounted inside the third guide cylinder to drive the display screen support plate to rotate along its axial direction.

[0011] The technical solution described in this application embodiment has at least the following technical effects: Through the combined design of three guide cylinders and three adjustment rods, multi-dimensional adjustment of the screen in three-dimensional space is achieved, breaking through the limitation of single horizontal adjustment and realizing three-dimensional adjustment of height, front / back, and angle. Users can freely combine adjustment parameters according to their own needs to find the most comfortable usage state. This fundamentally solves the problem of traditional stands having only a single adjustment range, and can accurately match the needs of users in different usage postures and scenarios.

[0012] In this embodiment, the output shaft of the longitudinal adjustment rod is rotatably connected to the center point of the display screen support plate, and the output shaft of the angle adjustment rod is rotatably connected to the display screen support plate.

[0013] With this technical solution, the output shaft of the longitudinal adjustment rod is connected to the center point of the support plate, which is equivalent to providing a rotation fulcrum for the screen. When the angle adjustment rod moves back and forth, the screen can rotate flexibly around the center point. At the same time, the connection of the center point can ensure that the screen is subjected to uniform force during the adjustment process, avoiding shaking or tilting caused by the shift of the center of gravity.

[0014] In this embodiment, the included angle between the central axes of the second guide cylinder and the third guide cylinder is less than 90 degrees.

[0015] In this technical solution, the second guide cylinder corresponds to the longitudinal adjustment rod (moving back and forth), and the third guide cylinder corresponds to the angle adjustment rod (driving the screen to rotate). The angle between their central axes is less than 90 degrees, meaning that the direction of movement of the angle adjustment rod, along the axis of the third guide cylinder, is not perpendicular to the direction of movement of the longitudinal adjustment rod, which is along the axis of the second guide cylinder, but rather at a certain angle. This tilted relationship allows the driving force of the angle adjustment rod on the screen to be more in line with the tangential direction of the screen's rotation, similar to a diagonal pry, enabling a wider range of angle changes with a smaller adjustment stroke.

[0016] In this embodiment, the vertical adjusting rod is provided with a plurality of annular grooves in an array, the first guide cylinder is provided with a first locking member, and the vertical adjusting rod can be moved in its axial direction through the annular grooves and the first locking member. The second guide cylinder is provided with a second locking member to restrict the movement of the longitudinal adjusting rod. The third guide cylinder is provided with a third locking member to restrict the movement of the angle adjusting rod.

[0017] This technical solution uses an array of annular grooves distributed along the axial direction of the vertical adjustment rod, effectively pre-setting multiple height positioning points. When the vertical adjustment rod moves up and down, the first locking member can engage with the corresponding annular groove, mechanically restricting its axial sliding and achieving stable locking after height adjustment. However, it can also rotate in its circumferential direction. Simultaneously, the spacing design of the annular grooves provides a more stepped feel to height adjustment, allowing users to select a fixed height according to their needs and avoiding irregular sliding. The second locking member targets the longitudinal adjustment rod, and the third locking member targets the angle adjustment rod. Together with the first locking member, they form a multi-dimensional locking system. Each adjustment dimension can be fixed independently without affecting the others.

[0018] In this embodiment, a ball joint is provided at the connection between the longitudinal adjusting rod and the angle adjusting rod and the display screen support plate, for the display screen support plate to rotate in its horizontal direction. A fourth locking member is also provided on the ball joint to restrict the rotation of the ball joint.

[0019] This technical solution, by adding a ball joint and a fourth locking element at the connection between the vertical adjustment rod, the angle adjustment rod, and the display support plate, further expands and optimizes the screen's adjustment dimensions. It allows for horizontal rotation, and its core function is to achieve flexible, omnidirectional micro-adjustment of the screen in the horizontal direction through universal rotation and precise locking. The ball joint, in conjunction with the fourth locking element and a knob-type locking structure, quickly fixes the screen's position after horizontal angle adjustment. By squeezing the ball of the ball joint against its outer casing, friction is used to limit rotation, ensuring the screen remains stable at the adjusted horizontal angle and preventing angle shifts due to touch or vibration.

[0020] In this embodiment, the base also includes a fixing plate and a clamping plate. A threaded post is fixedly disposed on the clamping plate, and a transmission hole is provided on the fixing plate for the threaded post to pass through. An abutment cap is also threadedly connected to the threaded post for locking the fixing plate and the clamping plate.

[0021] This technical solution, through the combination of a fixing plate, a clamping plate, a threaded post, and an abutment cover, enables the bracket to be detachably and stably clamped and installed on a desktop or other carrier. It can adapt to mounting surfaces of different thicknesses and ensure stability during use.

[0022] In this embodiment, a buffer pad is provided on the side of the fixing plate opposite to the clamping plate.

[0023] This technical solution involves setting buffer pads on opposite sides of the fixing plate and the clamping plate. The core function is to solve the two major problems of protecting the mounting surface and clamping stability through physical buffering and friction enhancement. Attached Figure Description

[0030] The lateral adjustment computer stands in related technologies have significant functional limitations. They can only allow the computer to move horizontally, offering a single adjustment dimension. Their adjustable range is strictly limited to this fixed horizontal dimension. They cannot adjust the height according to the user's sitting or standing posture, nor can they tilt the screen for different usage scenarios such as typing, watching movies, or drawing, resulting in a severe lack of adjustment flexibility. This design completely fails to cover the diverse needs of users in actual use. For example, when a user wants to stand up after sitting for a long time, the stand cannot be raised to match the eye level when standing; when a user wants to look down at the screen to reduce neck strain, the stand cannot provide an angle tilt function. Ultimately, it fails to meet the core demand for a comfortable user experience in different postures.

[0031] Based on this, in order to improve the technical problem that the computer stand in the related technology has a limited adjustment range, which cannot cover the diverse needs of users in actual use and ultimately fails to meet the core demand of users for a comfortable user experience in different postures, the embodiments of this application provide the following solutions.

[0032] Please refer to the following: Figures 1 to 4 This application provides a computer screen adjustment device, which includes a base 1 and a display screen support plate 2. The device is characterized by further including:

[0033] The first guide cylinder 3 is mounted on the base 1, and the vertical adjusting rod 31 is movably mounted inside the first guide cylinder 3, which is used to drive the display screen support plate 2 to move axially.

[0034] The second guide cylinder 32 is mounted on the output shaft of the vertical adjusting rod 31, and the longitudinal adjusting rod 33 is movably mounted inside the second guide cylinder 32, which is used to drive the display screen support plate 2 to move longitudinally.

[0035] The third guide cylinder 34 is fixedly mounted on the longitudinal adjusting rod 33. The central axes of the second guide cylinder 32 and the third guide cylinder 34 form an angle. An angle adjusting rod 35 is movably mounted inside the third guide cylinder 34 to drive the display screen support plate 2 to rotate along its axial direction.

[0036] The computer screen adjustment device provided in this application embodiment, through the combined design of three guide cylinders and three adjustment rods, realizes multi-dimensional adjustment of the screen in three-dimensional space, breaking through the limitation of single horizontal adjustment, and realizing three-dimensional adjustment of height, front-back, and angle. The first guide cylinder 3 and the vertical adjustment rod 31 are responsible for adjusting the height of the screen. The axial movement of the vertical adjustment rod 31 within the first guide cylinder 3 drives the display support plate 2 to rise and fall, adapting to different user postures such as sitting and standing. The second guide cylinder 32 and the vertical adjustment rod 33 are responsible for adjusting the front-back distance of the screen. The vertical adjustment rod 33 moves along the second guide cylinder 32, which can bring the screen closer or further away from the user, solving the problem of eye fatigue caused by the screen being too close or unclear details due to the screen being too far away. The third guide cylinder 34 and the angle adjustment rod 35 are responsible for adjusting the tilt angle of the screen. The central axis is angled at 34, and the angle adjustment lever at 35 rotates to rotate the screen along the axis, adjusting the screen's tilt angle to reduce glare and optimize the viewing angle, adapting to different usage scenarios such as typing, watching movies, and drawing. Users can freely combine and adjust parameters according to their own needs to find the most comfortable usage state, fundamentally solving the problem of traditional stands having limited adjustment range and single adjustment. It can accurately match the needs of users in different usage postures and scenarios, satisfying both daily seated office work and standing office work, through height adjustment; it can adapt to close-range typing to adjust to a suitable distance, and also adapt to long-distance movie viewing angle adjustment to a low-reflection state, covering diverse scenarios such as office work, entertainment, and creation. By precisely adjusting the screen height and angle, users can keep their line of sight horizontal or slightly downward with the center of the screen, reducing the bending pressure on the cervical and lumbar spine, and avoiding eye fatigue caused by improper distance, making long-term use healthier.

[0037] In this embodiment, the output shaft of the longitudinal adjustment rod 33 is rotatably connected to the center point of the display screen support plate 2, and the output shaft of the angle adjustment rod 35 is rotatably connected to the display screen support plate 2.

[0038] With this configuration, the output shaft of the vertical adjustment lever 33 is connected to the center point of the support plate, effectively providing a rotational fulcrum for the screen. When the angle adjustment lever 35 moves back and forth, the screen can rotate flexibly around this center point. Simultaneously, the center point connection ensures even force distribution on the screen during adjustment, preventing wobbling or tilting due to center of gravity shift. The angle adjustment lever 35, as an active adjustment component, has its output shaft rotated around the support plate, not at the center point, but typically at the edge or off-center. It can extend, retract, or rotate to change the screen's tilt angle around the axis connecting the vertical adjustment lever 33 and the center point. This combination of fulcrum and power point, similar to a lever structure, allows for precise control of the screen angle with minimal adjustment effort. Through optimized mechanical structure, linear and rotational adjustments are organically combined, making each screen adjustment action more ergonomic and enhancing the device's adaptability to diverse usage scenarios.

[0039] In this embodiment, the included angle between the central axes of the second guide cylinder 32 and the third guide cylinder 34 is less than 90 degrees.

[0040] With this configuration, the second guide cylinder 32 corresponds to the longitudinal adjustment rod 33 (forward and backward movement), and the third guide cylinder 34 corresponds to the angle adjustment rod 35 (for driving screen rotation). The angle between their central axes is less than 90 degrees, meaning that the direction of movement of the angle adjustment rod 35, along the axis of the third guide cylinder 34, is not perpendicular to the direction of movement of the longitudinal adjustment rod 33, which is along the axis of the second guide cylinder 32, but rather at a certain angle. This tilted relationship allows the driving force of the angle adjustment rod 35 on the screen to be more closely aligned with the tangential direction of the screen's rotation, similar to a diagonal pry, enabling a wider range of angle changes with a smaller adjustment stroke. Because the angle is less than 90 degrees, the axial movement of the angle adjustment rod 35 can be more efficiently converted into the screen's rotation angle. The non-perpendicular angle design makes the contact force between the angle adjustment rod 35 and the third guide cylinder 34 more uniform, avoiding localized wear caused by hard contact at a perpendicular angle; at the same time, the improved compatibility of their movement directions reduces jamming or stress concentration during adjustment, extending the device's lifespan.

[0041] In this embodiment, the vertical adjusting rod 31 is provided with a plurality of annular grooves 36 arranged in an array, the first guide cylinder 3 is provided with a first locking member 37, and the vertical adjusting rod 31 can be moved in its axial direction through the annular grooves 36 and the first locking member 37. The second guide cylinder 32 is provided with a second locking member 38, which is used to restrict the movement of the longitudinal adjusting rod 33. The third guide cylinder 34 is provided with a third locking member 39, which is used to restrict the movement of the angle adjusting rod 35.

[0042] With this configuration, the annular grooves 36 are arrayed along the axial direction of the vertical adjustment rod 31, effectively pre-setting multiple height positioning points. When the vertical adjustment rod 31 moves up and down, the first locking member 37 can engage with the corresponding annular groove 36, mechanically restricting its axial sliding and achieving stable locking after height adjustment. However, it can also rotate circumferentially. Simultaneously, the spaced design of the annular grooves 36 provides a more stepped feel to the height adjustment, allowing users to select a fixed height according to their needs and avoiding irregular sliding. The second locking member 38 targets the longitudinal adjustment rod 33, and the third locking member 39 targets the angle adjustment rod 35. Together with the first locking member 37, they form a multi-dimensional locking system. Each adjustment dimension can be fixed independently without affecting the others. Traditional brackets lacking a locking structure may experience positional shifts due to the screen's weight or minor impacts. The mechanical locking mechanism of the locking element and the annular groove 36 provides rigid fixation, ensuring that the screen posture will not easily change even with long-term use or mobile devices. This is especially suitable for scenarios that require a fixed viewing angle. While ensuring multi-dimensional adjustment flexibility, it solves the core pain point of instability after adjustment, allowing the device to flexibly adapt to different scenarios and stably maintain the best posture set by the user, further enhancing its practicality and reliability.

[0043] In this embodiment, a ball joint 4 is provided at the connection between the longitudinal adjustment rod 33 and the angle adjustment rod 35 and the display support plate 2, for the display support plate 2 to rotate in its horizontal direction. A fourth locking member 41 is also provided on the ball joint 4 to restrict the rotation of the ball joint 4.

[0044] This configuration, with the addition of a ball hinge 4 and a fourth locking element 41 at the connection between the vertical adjustment rod 33, the angle adjustment rod 35, and the display support plate 2, further expands and optimizes the screen's adjustment dimensions. It allows the screen to rotate horizontally. Its core function is to achieve flexible, omnidirectional micro-adjustment of the screen in the horizontal direction through universal rotation and precise locking. The ball hinge 4, in conjunction with the fourth locking element 41, uses a knob-type locking structure to quickly fix the screen's position after horizontal angle adjustment. By squeezing the ball of the ball hinge 4 against its outer casing, friction is used to limit its rotation, ensuring the screen remains stable at the adjusted horizontal angle and preventing angle shift due to touch or vibration.

[0045] In this embodiment, the base 1 also includes a fixing plate 11 and a clamping plate 12. A threaded post 13 is fixedly provided on the clamping plate 12. A transmission hole 14 is provided on the fixing plate 11 for the threaded post 13 to pass through. An abutment cover 15 is also threadedly connected to the threaded post 13 for locking the fixing plate 11 and the clamping plate 12.

[0046] This configuration, through the combination of the fixing plate 11, clamping plate 12, threaded post 13, and abutment cover 15, enables the bracket to be detachably and stably clamped onto surfaces such as desktops. It can adapt to mounting surfaces of different thicknesses and ensure stability during use. Compared to the traditional drilling-fixed base 1, this clamping design does not require drilling holes in the desktop and can be directly clamped onto desktops and partitions of different thicknesses. It can be used in home desks, office workstations, and temporary workbenches, avoiding damage to the mounting surface and having a wider range of applications.

[0047] In this embodiment, a buffer pad is provided on the side of the fixing plate 11 opposite to the clamping plate 12.

[0048] With this setup, buffer pads are placed on opposite sides of the fixing plate 11 and the clamping plate 12. The core function is to solve the two major problems of installation surface protection and clamping stability through physical cushioning and friction enhancement. Whether it is a wooden tabletop, glass tabletop, metal partition, or a fragile surface such as paint or stickers, the buffer pads can adapt to and provide protection, avoiding the problem of selective use due to different installation surface materials, and allowing the bracket to be installed safely in more scenarios.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
