[0034] Reference Figure 1-4 A foldable dual-screen display includes two displays 1 and a support 2 mounted on one side of one of the displays 1. A folding auxiliary mechanism is mounted between the two displays 1. The folding auxiliary mechanism includes a back protrusion 3, a first mounting strip 4, and a second mounting strip 5. The back protrusion 3 is fixed to the adjacent ends of the two displays 1. The two back protrusions 3 are rotatably connected by pins. The first mounting strip 4 is fixed to the top of one back protrusion 3, and the second mounting strip 5 is fixed to the top of the other back protrusion 3. The second mounting strip 5 is assembled and connected to the first mounting strip 4.

[0035] A limiter is installed between the first mounting strip 4 and the second mounting strip 5. The limiter is used to connect the first mounting strip 4 and the second mounting strip 5.

[0036] The limiter includes a mating groove 6, a connecting spring 7, a transmission rod 8, and a docking groove 9. The first mounting strip 4 has a mating groove 6 at one end near the second mounting strip 5. The connecting spring 7 is fixed to one end of the inner side of the mating groove 6, and the transmission rod 8 is fixed to one end of the connecting spring 7. The transmission rod 8 is slidably connected to the mating groove 6. The second mounting strip 5 has a docking groove 9 at one end near the first mounting strip 4. The docking groove 9 is slidably connected to the transmission rod 8. The setting of the docking groove 9 can limit and support the transmission rod 8.

[0037] The limiter also includes a base groove 10 and a force-applying rib 11. The top of the first mounting strip 4 is provided with a base groove 10, and the inner side of the base groove 10 is slidably connected to the force-applying rib 11. The force-applying rib 11 is fixed to the transmission rod 8. The setting of the force-applying rib 11 makes it easy for the user to quickly adjust the position of the transmission rod 8.

[0038] An adjustment mechanism is installed between the support 2 and the back protrusion 3. The adjustment mechanism is used to adjust the angle of the display screen 1.

[0039] The adjustment mechanism includes a transmission device and an auxiliary device. A mounting base 12 is fixed to the top of the support 2, a transmission device is mounted on the top of the mounting base 12, and an auxiliary device is mounted on the inner side of the transmission device.

[0040] The transmission device includes a transmission roller 13, a fixed sleeve 14, a support arm 15, a bending rib 16, and an auxiliary connecting rod 17. A transmission roller 13 is rotatably connected to both ends of the inner side of the mounting base 12. A fixed sleeve 14 is fixed to the outer side of the transmission roller 13. A support arm 15 is fixed to the outer side of the fixed sleeve 14. A bending rib 16 is rotatably connected to one end of the support arm 15. Auxiliary connecting rods 17 are rotatably connected to both sides of the bending point of the bending rib 16. One end of each auxiliary connecting rod 17 is rotatably connected to the mounting base 12. One end of the bending rib 16 is fixed to one of the back protrusions 3. It can be understood that the support arm 15 and the auxiliary connecting rod 17 are arranged in parallel. The auxiliary connecting rod 17 increases the support and limit of the bending rib 16. At the same time, a damper is provided at the rotatable connection between the auxiliary connecting rod 17 and the bending rib 16.

[0041] Further optimizations to Example 1, specifically, such as... Figure 5-7 As shown, the auxiliary device includes a synchronizing sleeve 18, a semi-U-shaped rod 19, a docking sleeve 20, a rotating rod 21, a force-applying worm gear 22, a guide worm wheel 23, a transverse shaft 24, a transmission disc 25, an arc-shaped internal groove 26, and an L-shaped guide rod 27. One end of the transmission roller 13 is fixed to the synchronizing sleeve 18, and one side of the support 2 is fixed to the semi-U-shaped rod 19. One end of the semi-U-shaped rod 19 is fixed to the docking sleeve 20, which is located inside the synchronizing sleeve 18 and aligned with its center. The top of the semi-U-shaped rod 19 is rotatably connected to the rotating rod 21, and the outer side of the rotating rod 21 is fixed to the force-applying worm gear 22. The outer side of the force-applying worm gear 22 is meshed with the guide worm wheel 23, and one side of the guide worm wheel 23 is fixed to the transverse shaft 24. The transverse shaft 24 is rotatably connected to the docking sleeve 20, and one end of the transverse shaft 24 passes through the docking sleeve 20 and is fixed to the transmission disc 25. 5. Multiple arc-shaped built-in grooves 26 are evenly distributed on the inner side of the transmission disc 25. L-shaped guide rods 27 are slidably connected to the inner side of each arc-shaped built-in groove 26. One end of each L-shaped guide rod 27 is slidably connected to the docking sleeve 20. When it is necessary to release the limit on the synchronous sleeve 18, the horizontal shaft 24 is rotated, so that the horizontal shaft 24 drives the guide worm gear 23 and the horizontal shaft 24 to rotate synchronously. Because the horizontal shaft 24 is fixed to the transmission disc 25, the arc-shaped built-in grooves 26 are slidably connected to the L-shaped guide rods 27, and the L-shaped guide rods 27 are slidably connected to the docking sleeve 20, when the transmission disc 25 rotates, the multiple L-shaped guide rods 27 can move along the arc-shaped built-in grooves 26, so that the multiple L-shaped guide rods 27 move towards the center of the transmission disc 25 until the L-shaped guide rods 27 drive the brake pad 28 to separate from the inner side of the synchronous sleeve 18.

[0042] The auxiliary device also includes a brake pad 28. One end of the L-shaped guide rod 27 passes through the docking sleeve 20 and is fixed with the brake pad 28. The brake pad 28 has anti-slip texture on the outside to increase the limiting ability of the synchronization sleeve 18.

[0043] In summary:

[0044] This utility model addresses the technical problem that most current monitors are single-screen structures. Due to the small size of these single screens, the display interface is not comprehensive enough, and angle adjustment is inconvenient, resulting in a less than ideal user experience that no longer meets user needs. The present invention employs the technical solutions described in the above embodiments. Furthermore, the implementation process of the above technical solutions is as follows:

[0045] During use, when it is necessary to fold the two displays 1 to a certain angle, pull the force-applying rib 11 so that the force-applying rib 11 moves along the inner side of the base groove 10, thereby causing the force-applying rib 11 to drive the transmission rod 8 to squeeze the connecting spring 7 to retract until the transmission rod 8 separates from the docking groove 9. Then rotate the two displays 1 so that the two displays 1 are at a certain folding angle to each other for easy use.

[0046] When the angle of the display screen 1 needs to be adjusted, pull down the bending rib 16, causing the bending rib 16 to drive the support arm 15 to rotate. Because the support arm 15 is fixed to the fixed sleeve 14, the fixed sleeve 14 is fixed to the transmission roller 13, the transmission roller 13 is rotatably connected to the mounting base 12, and the auxiliary connecting rod 17 is rotatably connected to the bending rib 16 and the mounting base 12, the bending rib 16 can drive the back protrusion 3 and the display screen 1 to rotate downward. After the adjustment is completed, rotate the horizontal shaft 24, causing the horizontal shaft 24 to drive the guide worm gear 23 and the horizontal shaft 24 to rotate synchronously. Because the horizontal shaft 24 is fixed to the transmission disk 25, the arc-shaped inner groove 26 is slidably connected to the L-shaped guide rod 27, and the L-shaped guide rod 27 is slidably connected to the docking sleeve 20, when the transmission disk 25 rotates, multiple L-shaped guide rods 27 can move along the arc-shaped inner groove 26, causing multiple L-shaped guide rods 27 to move away from the center of the transmission disk 25 until the L-shaped guide rods 27 drive the brake pad 28 to make tight contact with the inner side of the synchronous sleeve 18, so that the brake pad 28 forms a rotation limit on the synchronous sleeve 18, thereby realizing the stable adjustment of the angle of the display screen 1.

[0047] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects:

[0048] This utility model, through the structural design of the folding auxiliary mechanism, makes it easy to fold or unfold the two display screens 1. With the cooperation of the two display screens 1, the display interface can be comprehensive and complete, enabling dual-screen collaboration for viewing and processing documents. At the same time, when the two display screens 1 are aligned, the rotation limit of the two display screens 1 can be set, which speeds up the work efficiency. Furthermore, through the setting of the adjustment mechanism, the angle of the display screens 1 can be quickly adjusted, improving the user experience and enabling the display screens 1 to better serve people's lives and work.
