Description

Technical Field

[0001] This invention relates to the field of computer technology, specifically to an adjustable support device for a computer display screen. Background Technology

[0002] With the rapid development of digital office, e-sports entertainment, and professional design, computers have become an indispensable core device in people's daily work and life. Computer monitors are one of the important accessories; they are display tools that transmit electronic documents through specific equipment to the screen and then reflect them to the human eye. Computer monitors require support devices for placement, but existing computer monitor support devices still have certain shortcomings, such as:

[0003] The "Computer Display Screen Support Device" with application number CN202220059252.1 has two main drawbacks. First, it is inconvenient to adjust the position, making it difficult to adapt to the personalized needs of users of different heights and in diverse usage scenarios (such as sitting office, standing operation, and lying down to watch movies) regarding the height and tilt angle of the display screen. Long-term use can easily cause neck and lumbar fatigue in users, affecting their comfort. Second, it has poor placement stability and lacks an effective reinforcing structure to improve placement stability. The base support area is small, and it is easy to tip over due to collisions during daily use. This not only threatens the safety of use but may also lead to irreversible losses such as display panel breakage and damage to internal components, seriously affecting the service life of the equipment and the user experience.

[0004] In view of this, and in response to the above problems, an adjustable support device for computer displays was proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable support device for a computer display screen, so as to solve the problems mentioned in the background art of existing computer display screen support devices being inconvenient to adjust position and having poor placement stability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable support device for a computer display screen, comprising a base;

[0007] A column is fixedly installed on the top surface of the base, and a sliding column is longitudinally slidably installed through the top center of the column. A fixed seat is fixedly installed on the top surface of the sliding column, and a mounting shaft is provided on the fixed seat. The mounting shaft passes through the left and right side walls of the fixed seat in sequence through bearings, and a support arm is fixedly installed on the surface of the mounting shaft. A clamping mechanism for fixing a computer display screen is fixedly installed at the end of the support arm. A rotating mechanism for rotating the mounting shaft is provided on the fixed seat.

[0008] The base is provided with a drive mechanism for the lifting and moving of the sliding column, and the left side of the column is provided with an adsorption and stabilization mechanism, which is connected to the sliding column through a connecting mechanism.

[0009] The base is provided with an auxiliary support mechanism at its bottom to expand the support area, and the auxiliary support mechanism is connected to the drive mechanism through a transmission mechanism.

[0010] The above technical solution facilitates the adjustment of the display screen height and tilt angle, while improving the stability of the device placement, adapting to users of different heights and diverse usage scenarios, and balancing adjustment flexibility and usage safety.

[0011] As a preferred embodiment of the present invention, the clamping mechanism includes a sleeve frame fixedly installed at the end of the support arm. A bidirectional threaded rod is installed on the inner bottom surface of the sleeve frame through a bearing, and the bidirectional threaded rod passes through the top of the sleeve frame through a bearing. Two slide blocks are symmetrically sleeved on the outer side of the bidirectional threaded rod, and the bidirectional threaded rod is threadedly connected to the slide blocks. The slide blocks are longitudinally slidably connected to the inner wall of the sleeve frame. A clamping seat is fixedly installed at the end of the slide block, and a rubber protective pad is provided on the inner side of the clamping seat.

[0012] By adopting the above technical solution, it is easy to drive the two slides to move relative to each other or in opposite directions by rotating the bidirectional threaded rod, thereby driving the clamping base to move synchronously, so as to quickly clamp and fix computer screens of different sizes. The rubber protective pad can prevent scratches and damage to the screen frame during clamping, and increase the clamping friction to improve the fixing effect, thereby improving the safety and adaptability of the fixing process.

[0013] As a preferred embodiment of the present invention, the rotating mechanism includes a housing fixedly installed on the right side of the fixed base, and a worm gear is installed on the inner bottom surface of the housing through a bearing. The worm gear passes through the top of the housing through the bearing, and the worm gear is meshed with a worm wheel coaxially fixedly installed on the right end of the mounting shaft.

[0014] The above technical solution facilitates the rotation of the worm gear to drive the worm wheel, which in turn drives the mounting shaft and support arm to rotate synchronously, thereby adjusting the tilt angle of the display screen. Furthermore, the meshing structure of the worm gear and worm wheel has a self-locking function, which can keep the display screen stably at the adjusted angle, prevent it from shifting on its own during use, and improve the stability of use.

[0015] As a preferred embodiment of the present invention, the driving mechanism includes a rotating shaft that passes through the right side wall of the column through a bearing, and a bevel gear set is connected to the left end of the rotating shaft. The bevel gear set is fixedly installed on the surface of the lifting screw, and the lifting screw passes through the bottom center of the base through a bearing. The bottom end of the lifting screw is connected to the center of the inner bottom surface of the base through a bearing. The lifting screw extends into a threaded groove opened in the sliding column, and the sliding column is threadedly connected to the threaded groove.

[0016] By adopting the above technical solution, the lifting screw can be rotated by rotating the shaft and driven by the bevel gear set. The rotational motion is converted into the longitudinal linear motion of the slide column by the threaded engagement between the lifting screw and the internal thread groove of the slide column, so as to realize the smooth adjustment of the display screen height and adapt to the height requirements of different usage scenarios such as seated office work and standing operation.

[0017] As a preferred embodiment of the present invention, the adsorption stabilizing mechanism includes a cylinder fixedly installed on the left side of the column. A sliding rod is slidably installed through the top center of the cylinder, and a piston is fixedly installed at the bottom end of the sliding rod. The piston is located inside the cylinder, and the diameter of the piston matches the inner diameter of the cylinder. The upper end of the left side wall of the cylinder is fixedly connected to one end of a through pipe, and the through pipe is fixedly installed through the top of the base. The other end of the through pipe is fixedly connected to an annular pipe, and the annular pipe is fixedly installed on the inner top surface of the base. An air suction pipe is connected to the bottom of the annular pipe, and the air suction pipe is fixedly installed through the bottom of the base.

[0018] By adopting the above technical solution, the piston can be driven to move downward in the cylinder by the slide rod, so that negative pressure is generated inside the cylinder. Then, the air between the base and the placement surface is extracted through the through pipe, the ring pipe and the suction pipe, forming an adsorption and fixation effect, which significantly improves the stability of the device and effectively avoids the risk of tipping over due to collision.

[0019] As a preferred embodiment of the present invention, the air intake tubes are arranged in multiple uniform angles around the axis of the annular tube.

[0020] By adopting the above technical solution, the adsorption force can be evenly distributed at multiple positions on the bottom of the base, ensuring a firm adsorption between the base and the placement surface, avoiding a decrease in stability due to insufficient local adsorption force, and further improving the working reliability of the adsorption stabilization mechanism.

[0021] As a preferred technical solution of the present invention, the connecting mechanism includes a through groove opened on the left side wall of the column, and the wall surface of the through groove is rotatably connected to a connecting gear via a shaft. The connecting gear meshes with a first rack fixedly installed at the lower end of the left side of the sliding column, and the connecting gear meshes with a second rack fixedly installed at the end of the sliding rod.

[0022] By adopting the above technical solution, the lifting motion of the sliding column can be easily converted into the up-and-down movement of the sliding rod through the meshing transmission of the first rack, connecting gear and the second rack, realizing the linkage between the adsorption stabilization mechanism and the drive mechanism. While adjusting the height of the display screen, the adsorption fixation or release operation is automatically completed without additional manual control, thus improving the ease of use.

[0023] As a preferred technical solution of the present invention, the auxiliary support mechanism includes a sliding groove opened at the bottom of the base along its radial direction, and multiple sliding grooves are arranged at equal angles. A support bar is slidably connected inside the sliding groove along its length direction, and multiple balls are evenly installed on the bottom surface of the support bar.

[0024] By adopting the above technical solution, the support bar can slide along the groove to extend, thereby expanding the support area of ​​the base and improving the stability of the placement. In addition, the ball bearings can reduce the friction between the support bar and the placement surface when the support bar slides, making the extension and retraction adjustment of the support bar smoother and less labor-intensive.

[0025] As a preferred embodiment of the present invention, the bottom of the ball is coplanar with the bottom surface of the base.

[0026] By adopting the above technical solution, it is easy to ensure that after the support bar extends, the ball bearings and the bottom surface of the base simultaneously contact the placement surface, so that the device is subjected to uniform force, avoids placement tilt caused by the height deviation of the support bar, and ensures the stability of the support and the level state after adjustment.

[0027] As a preferred embodiment of the present invention, the transmission mechanism includes a slide plate fixedly installed on the inner end of the top surface of the support bar, and the top surface of the slide plate is slidably connected to the inner top surface of the base. A transmission screw is provided above the support bar, and the transmission screw passes through the slide plate and is threadedly connected to the slide plate. The outer end of the transmission screw is connected to the inner wall of the base through a bearing, and a driven bevel gear is coaxially fixedly installed on the inner end of the transmission screw. The driven bevel gear meshes with a driving bevel gear fixedly installed on the surface of the lifting screw.

[0028] By adopting the above technical solution, the rotational motion of the lifting screw can be driven by the active bevel gear and the driven bevel gear to rotate the transmission screw. The threaded engagement between the transmission screw and the slide plate drives the support bar to extend and retract along the slide groove, realizing the linkage between the auxiliary support mechanism and the drive mechanism. While adjusting the height of the display screen, the support area can be automatically expanded or reduced.

[0029] Compared with the prior art, the beneficial effects of the present invention are: the adjustable support device for the computer display screen is comprehensive in function, strong in stability and easy to use. It can flexibly adjust the height and angle of the display screen and lock itself, meeting the diverse usage needs of different users and improving user comfort; at the same time, it forms a strong adsorption force by vacuuming and can expand the support area, and improves the placement stability through a dual protection structure design; the structure is ingenious, and the adsorption fixation and support area adjustment are completed simultaneously when adjusting the height, without the need for additional operation, taking into account both adjustment flexibility and use safety, and extending the life of the equipment;

[0030] Comprehensive adjustment functions to meet diverse usage needs: Through the coordinated action of the rotating shaft, bevel gear set, and lifting screw in the drive mechanism, the rotational motion is smoothly converted into the longitudinal linear motion of the slide column, realizing flexible adjustment of the display screen height. This perfectly adapts to the height requirements of users of different heights and various scenarios such as sitting office, standing operation, and lying down to watch movies. Combined with the meshing transmission of the worm gear and worm wheel in the rotating mechanism, the tilt angle of the display screen can be easily adjusted. The self-locking characteristic of the worm gear and worm wheel structure ensures that the display screen remains stably at the adjusted angle, preventing it from shifting during use. This effectively alleviates neck and lumbar fatigue caused by long-term use and greatly improves user comfort. At the same time, the clamping mechanism drives the slide and clamping seat to move synchronously through the bidirectional threaded rod, which can quickly clamp computer displays of different sizes. The design of the rubber protective pad not only avoids scratching and damaging the display screen frame during clamping but also enhances the clamping friction, ensuring both the safety and adaptability of the fixation.

[0031] Outstanding stability and safe use: The adsorption stabilization mechanism uses a sliding rod to drive a piston to move within the cylinder, generating negative pressure. This negative pressure is then drawn out from between the base and the placement surface through a through-tube, annular tube, and multiple equally angled suction pipes, creating a uniform and powerful adsorption and fixation effect. This significantly improves the stability of the device and effectively avoids the risk of tipping over due to collisions. In the auxiliary support mechanism, the support bar can slide along the groove to extend, greatly expanding the support area of ​​the base and further enhancing placement stability. The ball bearings not only ensure that the support bar is coplanar with the bottom surface of the base after extension, making the device evenly stressed and preventing tilting, but also reduce the friction between the support bar and the placement surface when sliding, making the extension and retraction adjustment smoother and less strenuous.

[0032] 3. Ingenious structural design enhances ease of use: The adsorption and stabilization mechanism, through the meshing transmission of the first rack, connecting gear, and second rack in the connecting mechanism, is linked with the drive mechanism, automatically completing the adsorption and stabilization operation while adjusting the height of the display screen; the auxiliary support mechanism, through the cooperation of the driving bevel gear, driven bevel gear, and transmission screw in the transmission mechanism, is also linked with the drive mechanism, simultaneously expanding or shrinking the support area during height adjustment. This eliminates the need for manual control of multiple mechanisms, simplifying the operation process and making it more convenient and efficient for users. It balances adjustment flexibility and safety, extending the service life of the display screen equipment. Attached Figure Description

A second operating handwheel is coaxially fixedly installed on the right end of the rotating shaft 14. The bevel gear set 15 is fixedly installed on the surface of the lifting screw 16. The lifting screw 16 passes through the bottom center of the base 1 via a bearing, and the bottom end of the lifting screw 16 is connected to the center of the inner bottom surface of the base 1 via a bearing.

[0049] The adsorption stabilization mechanism includes a cylinder 18 fixedly installed on the left side of the column 2. The bottom of the cylinder 18 is open. A sliding rod 19 is slidably installed through the center of the top of the cylinder 18, and a piston 20 is fixedly installed at the bottom end of the sliding rod 19. The piston 20 is located inside the cylinder 18, and the diameter of the piston 20 matches the inner diameter of the cylinder 18. The upper end of the left side wall of the cylinder 18 is fixedly connected to one end of a through pipe 21, and the through pipe 21 is fixedly installed through the top of the base 1. The other end of the through pipe 21 is fixedly connected to an annular pipe 22, and the annular pipe 22 is fixedly installed on the inner top surface of the base 1. An air suction pipe 23 is installed at the bottom of the annular pipe 22, and the air suction pipe 23 is fixedly installed through the bottom of the base 1. Multiple air suction pipes 23 are evenly arranged at equal angles around the axis of the annular pipe 22.

[0050] The connecting mechanism includes a through groove 24 opened on the left side wall of the column 2, and a connecting gear 25 is rotatably connected to the wall of the through groove 24 via a shaft. The connecting gear 25 meshes with a first rack 26 fixedly installed at the lower end of the left side of the slide column 3, and the connecting gear 25 meshes with a second rack 27 fixedly installed at the end of the slide rod 19.

[0051] The auxiliary support mechanism includes a groove 28 opened on the bottom of the base 1 along its radial direction, and multiple grooves 28 are arranged at equal angles. A support bar 29 is slidably connected inside the groove 28 along its length direction, and multiple balls 30 are evenly installed on the bottom surface of the support bar 29. The bottom of the balls 30 is coplanar with the bottom surface of the base 1.

[0052] The transmission mechanism includes a slide plate 31 fixedly installed on the inner end of the top surface of the support bar 29, and the top surface of the slide plate 31 is slidably connected to the inner top surface of the base 1. A transmission screw 32 is provided above the support bar 29, and the transmission screw 32 passes through the slide plate 31 and is threadedly connected to the slide plate 31. The outer end of the transmission screw 32 is connected to the inner wall of the base 1 through a bearing, and a driven bevel gear 33 is coaxially fixedly installed on the inner end of the transmission screw 32. The driven bevel gear 33 is meshed with the driving bevel gear 34 fixedly installed on the surface of the lifting screw 16.

[0053] Working principle: First, place the device stably on a flat surface. Rotate the second operating handwheel on the right end of the rotating shaft 14. Through the bevel gear set 15 connected to the left end of the rotating shaft 14, the lifting screw 16 is driven to rotate synchronously. By means of the threaded engagement between the lifting screw 16 and the internal threaded groove 17 of the sliding column 3, the rotational motion is converted into the longitudinal upward motion of the sliding column 3.

[0054] During this process, the first rack 26 at the lower left side of the sliding column 3 moves upward synchronously with the sliding column 3 and meshes with the connecting gear 25 in the through groove 24, driving the connecting gear 25 to rotate. The connecting gear 25 then meshes with the second rack 27, driving the sliding rod 19 to move downward along the longitudinal direction of the cylinder 18 until the first rack 26 disengages from the connecting gear 25 and stops rotating the shaft 14. When the sliding rod 19 moves downward, it synchronously drives the piston 20 to slide in a sealed manner inside the cylinder 18, creating a negative pressure inside the cylinder 18. This negative pressure is transmitted through the through pipe 21 to the annular pipe 22 on the top surface of the base 1, and then through multiple suction pipes 23 distributed at equal angles at the bottom of the annular pipe 22, quickly extracting the air between the base 1 and the placement surface. The air pressure difference is used to achieve adsorption and fixation between the device and the table, thereby reducing the risk of tipping due to collision.

[0055] After the device is fixed, place the computer display screen between the two clamping bases 10. Rotate the first operating handwheel on the top of the sleeve frame 7 to drive the bidirectional threaded rod 8 to rotate. Since the bidirectional threaded rod 8 is threadedly connected to the two slides 9, and the slides 9 are limited by the inner wall of the sleeve frame 7 and are in a longitudinal sliding state, the rotation of the bidirectional threaded rod 8 will drive the two slides 9 to move closer to each other, thereby driving the clamping base 10 to move synchronously, so as to clamp and fix the display screens of different sizes. The rubber protective pad on the inner side of the clamping base 10 can not only avoid scratching and damaging the frame of the display screen during the clamping process, but also improve the clamping stability by increasing the friction and prevent the display screen from slipping.

[0056] To adjust the height of the display screen, continue to rotate the pivot 14 to control the slide column 3 to raise and lower until the display screen reaches the ideal height for scenarios such as seated office work or standing operation.

[0057] At the same time, when the lifting screw 16 rotates, it will drive the active bevel gear 34 on the surface to rotate synchronously. The active bevel gear 34 meshes with the driven bevel gear 33 to drive the transmission screw 32 to rotate. The transmission screw 32 is threadedly engaged with the slide plate 31, which drives the slide plate 31 to slide smoothly along the inner top surface of the base 1, thereby pushing the support bar 29 to extend outward along the slide groove 28 at the bottom of the base 1, so as to realize the adaptive adjustment of the support area and the height of the display screen. Since the ball bearings 30 on the bottom surface of the support bar 29 are coplanar with the bottom surface of the base 1, they can contact the placement surface of the base 1 synchronously after extending, ensuring that the device is evenly stressed, improving the support stability while ensuring the horizontal state of the display screen after adjustment.

[0058] To adjust the screen angle to suit different usage needs such as watching movies or working, turn the operating knob on the top of the housing 11 to rotate the worm gear 12. The worm gear 12 meshes with the worm wheel 13 at the right end of the mounting shaft 5, driving the mounting shaft 5 to rotate around the bearing of the fixed base 4. The mounting shaft 5 simultaneously drives the support arm 6 and the screen that is clamped and fixed to rotate until a comfortable angle is achieved. Thanks to the meshing structure of the worm gear 12 and the worm wheel 13, a self-locking function can be achieved after adjustment, so that the screen can be stably maintained at the adjusted angle, avoiding angle deviation due to vibration or touch during use, and ensuring the stability of the user experience.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
