DETAILED DESCRIPTION

[0017] A display lift according to the present invention, such as Figure 1 and Figure 2 As shown, it includes an arc-shaped lifting mechanism, on which a vertical plate 1 is fixedly installed. The arc-shaped lifting mechanism can be an arc-shaped lifting driving mechanism described in patent document CN201822016420.5, so as to drive the vertical plate 1 to perform arc-shaped lifting. Two fixed seats 2 are arranged side by side on the vertical plate 1, such as Figure 3 and Figure 4 As shown, each fixing seat 2 is provided with a circular through hole 3 and a first strip through groove 4, the circular through hole 3 and the first strip through groove 4 are connected, a rotating sleeve 5 is installed in each circular through hole 3, the rotating sleeve 5 can rotate in the circular through hole 3, and a second strip through groove 6 is provided on the rotating sleeve 5, and the second strip through groove 6 can be connected with the first strip through groove 4 during the rotation of the rotating sleeve 5.

[0018] A mounting plate 9 that can rotate relative to the stand plate 1 is installed between the two fixing seats 2. The mounting plate 9 is used to mount the display so that the display can be raised and lowered and the angle can be adjusted as required. The back of the top of the mounting plate 9 is fixedly installed with a rotating shaft 7. Figure 5 As shown, both ends of the rotating shaft 7 are provided with strip-shaped blocks 8, and the strip-shaped blocks 8 can respectively cooperate with the first strip-shaped through groove 4 and the second strip-shaped through groove 6. When the strip-shaped block 8 is located in the first strip-shaped through groove 4, the rotating shaft 7 no longer rotates relative to the fixing seat 2, and the mounting plate 9 and the vertical plate 1 remain relatively stationary. When the strip-shaped block 8 is located in the second strip-shaped through groove 6, the rotating shaft 7 can rotate in the circular through hole 3 following the rotating sleeve 5, that is, the mounting plate 9 can rotate relative to the vertical plate 1 to adjust the angle position of the display. Figure 6 As shown, a positioning slot 10 is fixedly installed on the vertical plate 1, and a hook 11 that cooperates with the positioning slot 10 is installed on the mounting plate 9. When the strip block 8 is located in the first strip through groove 4, the hook 11 cooperates with the positioning slot 10 to further ensure the relative fixed state of the mounting plate 9 and the vertical plate 1. When the strip block 8 is located in the second strip through groove 6, the hook 11 is separated from the positioning slot 10, and the unlocked mounting plate 9 and the vertical plate 1 can rotate relative to each other.

[0019] like Figure 2 As shown, a curved plate 12 is provided at the bottom of the mounting plate 9, and an unlocking wheel 13 is installed at the position where the curved plate 12 extends out of the mounting plate 9, and rolling wheels 14 are also installed at the positions on both sides of the bottom of the mounting plate 9. The unlocking wheel 13 and the rolling wheel 14 are for facilitating the angle change of the mounting plate 9 during the descent process, so that the display is gradually laid flat on the desktop for the user to look down on. The provision of the curved plate 12 can make it easier for the mounting plate 9 to change its angle with the vertical plate 1 during the descent process.

[0020] When the display lift is installed, the arc-shaped lifting mechanism is located below the desktop, and the mounting plate 9 and the vertical plate 1 are both located above the desktop. When the display on the mounting plate 9 is in a normal vertical position, the unlocking wheel 13 needs to be a certain distance away from the desktop or just on the desktop. Figure 2 The figure is a schematic diagram of the structure of the mounting plate 9 in a vertical state. The mounting plate 9 drives the rotating shaft 7 to descend under the action of gravity. The bar blocks 8 at both ends of the rotating shaft 7 fall into the first bar through groove 4 and no longer rotate. The hooks 11 extend into the positioning grooves 10 to further define the relative position of the mounting plate 9 and the vertical plate 1. When the display needs to be looked up, Figure 8 As shown in the figure, the arc-shaped lifting mechanism drives the vertical plate 1 to rise in an arc shape. Due to the matching positioning of the hook 11 and the positioning slot 10 and the rotation axis 7 falling into the first strip-shaped through-slot 4, it no longer rotates. During the arc-shaped rising process of the vertical plate 1, the mounting plate 9 and the display thereon remain in the same position relative to the vertical plate 1, and finally rise to Figure 8 When the user needs to look down at the display, such as Fig. 9 As shown, the arc-shaped lifting mechanism drives the vertical plate 1 to descend in an arc shape until the unlocking wheel 13 touches the desktop. At this time, the vertical plate 1 continues to descend. During the descent of the vertical plate 1, the hook 11 gradually separates from the positioning slot 10, and the strip blocks 8 at both ends of the rotating shaft 7 also enter the second strip through-slot 6 of the rotating sleeve 5 from the first strip through-slot 4. Then, the mounting plate 9 can rotate relative to the vertical plate 1, and the vertical plate 1 continues to descend in an arc shape. Under the action of the arc plate 12, the mounting plate 9 can easily change the angle with the vertical plate 1, and finally, under the joint action of the unlocking wheel 13 and the rolling wheel 14, the mounting plate 9 is driven to slide on the desktop until the mounting plate 9 is in the position as shown in FIG. Fig. 9 The user can look down and watch the display screen until it is almost flat on the desktop. The angle of the display can be adjusted by simply controlling the lifting height of the arc-shaped lifting mechanism. The entire operation process is simple and easy to implement, which can effectively change the user's posture when watching the display and relieve the fatigue of the user's cervical or lumbar spine caused by the same posture for a long time.

[0021] Furthermore, if Figure 2As shown, the arc-shaped lifting mechanism includes a base 15, in which a motor 16 and an arc-shaped lifting plate 17 are installed, and a slideway matching the arc-shaped lifting plate 17 is also provided in the base 15. Figure 1 and Figure 6 As shown, a long groove 18 is provided on the arc-shaped lifting plate 17, and a rack 19 is provided on the arc-shaped lifting plate 17 at one side of the long groove 18. A gear 20 matching the rack 19 is installed on the output shaft of the motor 16. The top of the arc-shaped lifting plate 17 is detachably connected to the vertical plate 1 by bolts. When the motor 16 is started, it can drive the vertical plate 1 to perform arc-shaped lifting and lowering, thereby completing the arc-shaped lifting and lowering of the display and adjusting the angle during the lifting and lowering process.

[0022] Furthermore, in order to facilitate the disassembly and assembly between the rotating shaft 7 and the fixing seat 2 on the vertical plate 1, a fixing block 29 is installed on the back of the mounting plate 9, and a mounting sleeve 30 matching the rotating shaft 7 is provided on the upper side of the fixing block 29. Figure 7 As shown, the rotating shaft 7 is located in the mounting sleeve 30, is fixedly connected to the mounting sleeve 30 and can rotate synchronously with the mounting sleeve 30 to ensure the synchronous rotation of the rotating shaft 7 and the mounting plate 9, while also making the disassembly and assembly between the vertical plate 1 and the mounting plate 9 more convenient.

[0023] Furthermore, in order to facilitate the fixation of the display, the four corners of the mounting plate 9 are provided with mounting holes 21, and the mounting holes 21 are used to fix the back of the display. A display bottom bracket 22 may also be installed at the bottom of the mounting plate 9 to facilitate placing the display on the mounting plate 9. At the same time, a display positioning device is installed on the top of the mounting plate 9. The display positioning device may be an existing clip to ensure that the top of the display is fixed on the mounting plate 9 to avoid falling off during the arc lifting process.

[0024] Furthermore, a display positioning device is installed side by side on the top of the mounting plate 9, such as Figure 2As shown, each display positioning device includes a fixing sleeve 23, which is mounted on the back of the mounting plate 9, and a slide bar 24 is installed in the fixing sleeve 23. The upper end of the slide bar 24 is fixedly installed at the position where the upper end of the slide bar 24 protrudes from the mounting plate 9, and a positioning screw 26 is also installed on the fixing sleeve 23. The slide bar 24 can be fixed in the height direction in the fixing sleeve 23 by rotating the positioning screw 26. When installing the display, first put the bottom of the display into the display bottom bracket 22, then rotate the positioning screw 26 so that the slide bar 24 can be freely raised and lowered in the fixing sleeve 23, and then put the upper end of the display into the display upper clamping block 25, adjust the distance between the display upper clamping block 25 and the display bottom bracket 22 according to the height of the display, rotate the positioning screw 26 to lock the slide bar 24, and under the joint action of the display upper clamping block 25 and the display bottom bracket 22, the display can be fixed on the mounting plate 9, and at the same time, the display can be prevented from falling off during the arc lifting process, and the entire installation process is also simple to implement.

[0025] Furthermore, an elastic pad 27 is installed on the mounting plate 9. The setting of the elastic pad 27 can enable the display upper clamp 25 to adapt to displays of different thicknesses and types, thereby improving the use range of the device. Rubber pads 28 are provided on the inner sides of the display bottom bracket 22 and the display upper clamp 25. The rubber pads 28 can protect the installed display and avoid damage to the display itself due to excessive clamping force while clamping.

[0026] Furthermore, in order to facilitate the adjustment of the position where the mounting plate 9 starts to rotate in angle as needed during the arc lifting process of the vertical plate 1, that is, the initial distance between the unlocking wheel 13 and the desktop, the arc plate 12 is provided with a strip groove 31, and a fastening bolt 32 is installed in the strip groove 31. The stud of the fastening bolt passes through the strip groove 31 and is fixed on the mounting plate 9. The nut of the fastening bolt 32 can press the arc plate 12 on the mounting plate 9. By loosening the fastening bolt 32 and adjusting the position of the fastening bolt 32 in the strip groove 31 as needed, the distance that the unlocking wheel 13 at the bottom of the arc plate 12 extends out of the mounting plate 9 can be adjusted, thereby changing the position where the mounting plate 9 starts to rotate in angle. In order to adapt to the unlocking position of the unlocking wheel 13 after the position is changed, the installation distance between the hook 11 and the mounting plate 9 can also be adjusted accordingly. Matching long holes can be opened at the connection position between the hook 11 and the mounting plate 9, and detachable bolt fasteners are installed in the long holes to adjust the installation distance between the hook 11 and the mounting plate 9.
