Abstract
Description
Technical Field
[0001] The invention relates to the technical field of display screens, and in particular to a conference display screen capable of being adjusted at multiple angles. Background Art
[0002] Conference display screens are display devices specifically used in conference rooms. They are usually used to display presentations, data visualization, video conferencing, and other types of information to improve meeting efficiency and communication quality. The displays are used to display various data charts, statistical information, pictures, and documents, etc., to help participants quickly understand key data and trends and better support the decision-making process.
[0003] When adjusting the angle of conference display screens on the market, it is generally achieved by adjusting the angle of the bracket of the conference display screen, and then limiting the angle of the bracket. The limiting methods on the market include damping rotation card-type limiting, which can achieve both a fixing effect and adjustment of the rotation angle.
[0004] However, the damped rotating clip-on limiter also has certain shortcomings. For example, after long-term use, the spring of the damped rotating clip-on limiter is repeatedly stretched and compressed during long-term use, and its internal structure will gradually change. For example, the metal wire of the spring may have slight plastic deformation, which will accumulate with the increase in the number of uses. When it accumulates to a certain extent, it will cause the elasticity of the spring to decrease, causing the conference display screen to be unable to stabilize at the set angle.

The rotating cavity on the first sleeve 4 and the rotating cavity on the second sleeve 6 are both provided with a card slot 12, the number and position of which are adapted to the adjusting block 10, and the card slot 12 is communicated with the cavity 7, the part of the adjusting block 10 inside the card slot 12 is fixedly connected with the supporting spring 15, the other end of the supporting spring 15 is fixed on the hemispherical card block 14, the hemispherical card block 14 can do telescopic movement inside the card slot 12, damping grooves 13 are provided on the boss of the mounting seat 2 and the boss of the connecting seat 5, when the boss of the mounting seat 2 is stationary inside the first sleeve 4, the spherical part of the hemispherical card block 14 is stuck in the damping groove 13 under the elastic force of the spring, and the mounting seat 2 is limited, when the display screen body 1 is rotated, the display screen body 1 drives the mounting seat 2 to rotate, The mounting seat 2 will rotate inside the first sleeve body 4 with the boss as the axis. At this time, the hemispherical block 14 is subjected to compression force and moves into the internal slot 12 of the mounting seat 2. When it reaches a suitable angle, it is re-engaged in the damping slot 13 to achieve the horizontal angle adjustment of the display screen body 1. When the boss of the connecting seat 5 is stationary inside the second sleeve body 6, the hemispherical block 14 is engaged in the damping slot 13 with the elastic force of the spring to limit its connecting seat 5. When the display screen body 1 is pulled down or moved up, the display screen body 1 drives the mounting seat 2 to move. The mounting seat 2 is flipped with the connection between the boss of the connecting seat 5 and the second sleeve body 6 as the axis. The connecting seat 5 will rotate inside the first sleeve body 4 with the boss as the axis. At this time, the hemispherical block 14 is subjected to compression force and moves into the internal slot 12 of the mounting seat 2. When it reaches a suitable angle, it is re-engaged in the damping slot 13 to achieve the tilt angle adjustment of the display screen body 1.
[0033] In more depth, the transmission mechanism 11 includes a first bevel gear 111, the surface of the first bevel gear 111 is meshed with a plurality of second bevel gears 112 fixedly sleeved with the screw rod 9, the front of the first sleeve body 4 and one side of the second sleeve body 6 are both rotated with a rotating rod 113, one end of the rotating rod 113 penetrates into the interior of the cavity and is fixedly sleeved with the first bevel gear 111, the front of the first sleeve body 4 and one side of the second sleeve body 6 are both provided with a rotating disk 23, and the center of the rotating disk 23 is fixedly sleeved with the rotating rod 113, as shown in FIG. Figure 1 , Figure 3 and Figure 6As shown, the front side of the first sleeve 4 and one side of the second sleeve 6 are rotatably connected with a rotating rod 113, and the rotating disk 23 is designed on the rotating rod 113. The two rotating rods 113 can rotate on the first sleeve 4 and the second sleeve 6. The rotating rod 113 inside the first sleeve 4 and the second sleeve 6 is fixedly sleeved with the first bevel gear 111. When the rotating rod 113 rotates, the first bevel gear 111 can be driven to rotate, and the second bevel gear 112 is meshed with the first bevel gear 111. The rotation of the first bevel gear 111 can drive the second bevel gear 112 to rotate. The second bevel gear 112 is fixedly sleeved on one end of the screw rod 9. The rotation of the second bevel gear 112 can drive the screw rod 9 to rotate. After the screw rod 9 rotates, it can drive the adjusting block 10 to move under the action of the sliding limit of the card slot 12. When the adjusting block 10 moves, the supporting spring 15 can be compressed to ensure the supporting force of the supporting spring 15 on the hemispherical card block 14.
[0034] Specifically, when the rotating rod 113 rotates, under the action of the first bevel gear 111 and the second bevel gear 112, the screw rod 9 can be driven to rotate. After the screw rod 9 rotates, it can drive the adjusting block 10 to move under the action of the sliding limit of the card slot 12. When the adjusting block 10 moves, the support spring 15 can be compressed to increase the supporting elastic force of the support spring 15 on the hemispherical block 14. When the support spring 15 is fatigued, the elastic force of the support spring 15 can be increased to avoid the situation where the conference display screen is not firmly fixed when the angle is adjusted.
