Description

Technical Field

[0001] This utility model relates to the technical field of display support equipment, specifically a rear-mounted reinforced display adjustment bracket. Background Technology

[0002] With the widespread use of monitors in various fields, the demand for wall-mounted installations is constantly growing. Users have put forward higher requirements for the adjustment flexibility, installation stability, durability and ease of operation of monitor stands. Especially in scenarios such as office meetings, medical imaging diagnosis and e-sports games where the monitor viewing angle needs to be frequently adjusted, the performance defects of traditional stands are becoming more and more obvious.

[0003] Traditional brackets can only fix the monitor at a vertical angle. When the monitor is hung high, the vertically installed screen requires users to look up to view and operate it, which is not only inconvenient to use, but also easy to cause cervical fatigue in the long run. Moreover, in special installation positions such as the side of the equipment cabinet, traditional brackets cannot adjust the screen orientation, which seriously affects the efficiency of human-computer interaction.

[0004] Meanwhile, some stands adopt a single-axis rotation structure, which is prone to wobbling when making multi-dimensional adjustments. When the monitor is heavy, there is even a safety hazard of the entire stand tilting or falling off. It is difficult to meet the needs of modern diverse scenarios for high precision, high stability and convenience of monitor stands. To this end, we have proposed a rear-reinforced monitor adjustment stand. Utility Model Content

One end of angle rod one is hinged to the square support via the adjustment knob, and the other end is rotatably connected to angle rod two. The other end of angle rod two is sleeved on the long side of the T-shaped shaft.

[0011] The VESA plate rotation mechanism includes a T-shaped shaft, a lubricating bearing, a hand-tightening knob, a connecting plate, and a VESA plate. The long end of the T-shaped shaft is connected to the inside of the lubricating bearing. A hand-tightening knob is provided on one side of the lubricating bearing, passing through the side of the lubricating bearing and contacting the T-shaped shaft. The hand-tightening knob is connected to the center of the surface of the connecting plate, and the connecting plate is connected to the center of the inside of the VESA plate.

[0035] Furthermore, the contact surfaces of the lower tooth column 4 and the upper tooth column 5 are uniformly provided with gear meshing tooth structures.

[0041] Structural Description:

[0042] 1. Mounting base 1: It is an L-shaped metal plate with a square support 2 and a circular support 3 on the vertical surface, and multiple mounting holes are distributed thereon. The positioning hole is set in the center of the horizontal surface. It can be firmly fixed to the required installation position through the mounting holes.

[0043] 2. Square support 2: Extends from the upper end of the vertical surface of the mounting base 1, has a square structure, and is provided with a hinge hole for hinge angle rod 8, which is the connection base of the intermediate adjustment mechanism.

[0044] 3. Circular support 3: Located at the lower end of the vertical surface of the mounting base 1, it has a circular structure and a positioning hole in the center for positioning and mounting the upper gear column 5. In the meshing indexing mechanism, it plays the role of positioning and supporting the rotary joint 6.

[0045] 4. Lower toothed column 4: The lower end is a cylindrical base, which is fixed to the mounting base 1 through the positioning hole. The upper end is provided with a cylinder with internal teeth, which is fixed to the positioning hole of the mounting base 1. It cooperates with the upper toothed column 5 to realize the basic connection for horizontal rotation of the display, and the teeth are used for angle positioning.

[0046] 5. Upper toothed column 5: The lower end has a toothed shape that meshes with the lower toothed column 4. The upper end is a non-circular cross-section shaft that passes through the circular support 3 and connects to the rotary joint 6. It works with the lower toothed column 4 to realize the horizontal rotation of the display. Its upper end rectangular shaft design can achieve circumferential positioning with the rotary joint 6.

[0047] 6. Rotary joint 6: The bottom center has a rectangular positioning hole for connecting the upper gear column 4. Symmetrical brackets on both sides are connected to the T-shaped shaft 7, transmitting the rotation of the upper gear column 4 to the T-shaped shaft 7. At the same time, its rectangular hole cooperates with the upper gear column 4 to prevent circumferential slippage.

[0048] 7. T-shaped shaft 7: It is T-shaped, with the two ends of the short side connected to the rotary joint 6, and the long side used to fit the angle rod 9. The long end face is connected to the inside of the lubricating bearing 11. It is a key component connecting the meshing indexing mechanism, the intermediate adjustment mechanism and the VESA plate rotation mechanism, and transmits the motion between the various mechanisms.

[0049] 8. Angle lever 1: One end has a round hole and is hinged to the square support 2 through the adjustment knob 10. The other end has a shaft hole and is rotatably connected to angle lever 2 9. Under the drive of the adjustment knob 10, the angle lever 2 9 is driven to move, thereby realizing the adjustment of the monitor's tilt angle.

[0050] 9. Angle lever 2: One end is connected to angle lever 1 8, and the other end is provided with a bearing hole to fit onto the long side of T-shaped shaft 7. Together with angle lever 1 8, it realizes the adjustment and support of the display tilt angle in the intermediate adjustment mechanism.

[0051] 10. Adjustment knob 10: The hand-tight end is hexagonal, and the shaft end is equipped with a protruding key. By rotating the knob, the protruding key drives the angle rod 8 to move around the square support in a circular motion to adjust and lock the pitch angle.

[0052] 11. Lubricating bearing 11: The inner hole fits with the long end of the T-shaped shaft 7, allowing the T-shaped shaft 7 to rotate flexibly. The back is fixedly connected to the connecting plate 13 to transmit rotation. There is a threaded hole on one side. By rotating the hand-tightening knob 12 through the threaded hole, the T-shaped shaft 7 is locked to limit its horizontal rotation angle.

[0053] 12. Hand-tightening knob 12: The end is embedded with a rubber pad, which can pass through the threaded hole on the side of the lubricating bearing 11 and contact the outer circumferential surface of the T-shaped shaft 7. By tightening or loosening, the friction between the rubber pad and the T-shaped shaft 7 is used to lock and adjust the horizontal rotation angle of the display.

[0054] 13. Connecting plate 13: The center is fixed to the lubrication bearing 11, and there are waist-shaped mounting holes around it to connect the lubrication bearing 11 and the VESA plate 14. The position of the VESA plate 14 can be adjusted as required through the waist-shaped mounting holes.

[0055] 14. VESA plate 14: The surface has two sets of standard VESA mounting holes, and the back is fixed to the connecting plate 13. It is used to mount the monitor, so that it can be reliably connected to the bracket, and the angle can be adjusted through the connecting plate 13 and other components.

[0056] Working principle:

[0057] During installation, the L-shaped mounting base 1 is fixed to the required installation position with bolts through the mounting holes on the vertical surface. The square support 2 and the round support 3 on it serve as the mounting fulcrum for the intermediate adjustment mechanism and the meshing indexing mechanism, respectively.

[0058] When performing horizontal rotation adjustment, the upper gear column 5 is manually adjusted. After the upper gear column 5 rotates, it drives the rotary joint 6 to make a circular motion on the circular bracket 3. The rotary joint 6 then transmits the motion to the T-shaped shaft 7, which in turn drives the lubricating bearing 11, the connecting plate 13, and the VESA plate 14 to make the same circular motion around the axis of the rotary joint 6, thereby realizing the horizontal rotation of the display. During this process, the lower end of the upper gear column 5 is tightly meshed with the toothed end face of the lower gear column 4. The angle change is realized through gear meshing, controlling the horizontal rotation angle of the display and completing the horizontal rotation adjustment. At the same time, the rectangular shaft at the upper end of the upper gear column 5 cooperates with the rotary joint 6 to prevent circumferential slippage and ensure rotation accuracy.

[0059] The tilt angle adjustment relies on the intermediate adjustment mechanism. When the adjustment knob 10 is rotated, the key protruding from its shaft end engages with the internal positioning groove of the angle rod 8, causing the angle rod 8 to swing around the hinge hole of the square support 2. The angle rod 8 is rotatably connected to the angle rod 9 through the shaft hole, causing the angle rod 9 to move. Since the other end of the angle rod 9 is sleeved on the long side of the T-shaped shaft 7, the movement of the angle rod 9 causes the T-shaped shaft 7 to move around its own short axis, thus realizing the tilt angle adjustment of the display.

[0060] Horizontal rotation and tilt adjustment are achieved by the VESA plate rotation mechanism. Loosen the hand knob 12 to release the constraint of the rubber pad at its end on the T-shaped shaft 7, and the VESA plate 14 can be rotated. The VESA plate 14 is connected to the lubricating bearing 11 through the connecting plate 13. The long end of the T-shaped shaft 7 is engaged with the inner hole of the lubricating bearing 11 to rotate, driving the display to perform horizontal rotation and tilt adjustment. After adjusting to the appropriate angle, tighten the hand knob 12 to lock the required adjustment angle by using the friction between the rubber pad and the T-shaped shaft 7.

[0061] Throughout the entire process, the mounting base 1 provides stable support, the interlocking indexing mechanism ensures horizontal rotation accuracy, the intermediate adjustment mechanism enables tilt adjustment, and the VESA plate rotation mechanism completes fine horizontal rotation and tilt adjustment. All components work closely together to provide the monitor with flexible and stable adjustment functions.

[0062] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
