[0002] With the continuous development of display technology, high-definition displays have entered the lives of more and more people. For the purpose of stability, the existing display bases are mostly designed in triangular, rectangular, circular and other structures. Usually, there are partitions on the office desk to divide it into multiple workstations. When using it on a limited office desk, the position of the display needs to be adjusted backward. After the above-mentioned display base is moved to fit the partition, there is still a lot of space between the display and the partition that cannot be moved. The front and rear position of the display on the base cannot be adjusted according to actual needs. If the base structure is changed, the overall weight of the display is placed backward, which is easy to cause poor stability. Summary of the invention

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The high-definition display, adjustment components, and stabilization components are fixed together with bolts. During the packaging process, the entire assembly can be disassembled to facilitate packaging.

[0013] 2. When the high-definition display drives the fixed plate to rotate along the support frame for angle adjustment, the damping effect is generated in conjunction with the damping shaft to position and stabilize the high-definition display after rotation. If it is used on a limited office desktop, the pull rope is pulled downward to drive the fixed block and the connecting piece to move downward at the same time, squeezing the reset spring, and the downward connecting piece will drive the two connected groups of cards to rotate along the two groups of fixed axes respectively, so that the two groups of cards leave the card slots engaged on the two side slides respectively, and the high-definition display can be directly pushed backward. The support frame and the connecting seat slide along the two groups of slides, and then the pull rope is released. The reset spring rebounds to lift the connecting piece and the two groups of cards, and the two groups of cards are respectively inserted into the inner sides of the card slots on both sides to position the adjusted high-definition display and adjust the high-definition display front and back. When the base is limited in movement on the desktop, the high-definition display can also be moved backward, thereby improving the adjustment changes under actual conditions.

[0014] 3. When the connecting seat moves backward, the two sets of pulling blocks on the connecting seat respectively drive the two sets of fixed sleeves to move together, and the synchronous belt is driven to rotate along the two sets of synchronous wheels, driving the two sets of synchronous wheels and the front transmission rod and docking block to rotate, and the rotating docking block can drive the stabilizing component.

[0015] 4. The two rotating docking blocks respectively drive the two engaged blocks and gears to rotate along the shaft blocks. The two gears respectively drive the two engaged racks and the counterweight plate to slide forward along the positioning bolts. A number of balls arranged at the bottom of the counterweight plate promote the movement of the counterweight plate during the movement. The two counterweight plates moved to the front side of the base can prevent the high-definition display from moving backward while the center of gravity is biased to the rear, resulting in poor support stability. The increase in weight on the front side of the base just compensates for the unstable changes after adjustment, so that the adjusted high-definition display can be stably supported.

The two counterweight plates 37 moved to the front side of the base 33 can prevent the high-definition display 1 from moving backward while the center of gravity is biased to the rear side, resulting in poor support stability. The increase in weight on the front side of the base 33 just compensates for the unstable changes after adjustment, so that the adjusted high-definition display 1 can be stably supported.

[0029] Working principle: First, the high-definition display 1, the adjustment component 2, and the stabilizing component 3 are fixed together by bolts. During the packaging process, the whole can be disassembled to facilitate the packaging work. When in use, the high-definition display 1 drives the fixing plate 21 to rotate along the support frame 22 to adjust the angle, and the damping shaft 23 produces a damping effect to position and stabilize the high-definition display 1 after rotation. If it is used on a limited office desk, by pulling the pull rope 211 downward, the fixing block 210 and the connecting piece 29 move downward at the same time, squeezing the reset spring 212, and the downward The connecting piece 29 will drive the two connected groups of cards 28 to rotate along the two groups of fixed shafts 27 respectively, so that the two groups of cards 28 leave the card slots 215 engaged on the two side slides 214 respectively, and the high-definition display 1 can be directly pushed backward, the support frame 22 and the connecting seat 24 slide along the two groups of slides 214, and then the pull rope 211 is released, and the reset spring 212 rebounds to lift the connecting piece 29 and the two groups of cards 28, and the two groups of cards 28 are respectively inserted into the inner sides of the card slots 215 on both sides to position the adjusted high-definition display 1, and the high-definition display 1 is adjusted forward and backward, and the base 33 is on the table. When the movement on the surface is limited, the high-definition display 1 can also be moved backward, thereby improving the adjustment changes under actual conditions; while the connecting seat 24 moves backward, the two groups of pull blocks 25 on the connecting seat 24 respectively drive the two groups of fixing sleeves 220 to move together, and the synchronous belt 219 is driven to rotate along the two groups of synchronous wheels 218, driving the two groups of synchronous wheels 218 and the front transmission rod 221 and the docking block 222 to rotate, and the rotating docking block 222 can drive the stabilizing component 3; in addition, the two rotating docking blocks 222 respectively drive the two engaged groups The block 312 and the gear 311 rotate along the shaft block 310, and the two sets of gears 311 respectively drive the two meshing racks 39 and the counterweight plate 37 to slide forward along the positioning bolt 36. The plurality of balls 313 arranged at the bottom of the counterweight plate 37 promote the movement of the counterweight plate 37 during the movement. The two sets of counterweight plates 37 moved to the front side of the base 33 can prevent the center of gravity of the high-definition display 1 from being biased to the rear side while the high-definition display 1 moves backward, resulting in poor support stability. The increase in weight on the front side of the base 33 just compensates for the unstable changes after adjustment, so that the adjusted high-definition display 1 can be stably supported.

[0030] The structures of the high-definition display 1, damping shaft 23 and the like in the present invention are common knowledge in the field, and their working principles are already known technologies, and the models are selected according to actual use, so they will not be explained in detail.
