Description

Technical Field

[0001] The utility model relates to the technical field of split-screen display devices, in particular to a split-screen display device for a notebook computer screen. Background Art

[0002] Laptop computers are a common type of computer terminal on the market. They typically consist of a single display screen and a flat computer body. During use, the display's contents are visible only from the illuminated side of the computer; they are not visible from the back or sides. Some specialized laptops feature dual or even triple screens. For example, portable dual-screen laptops designed for special occasions feature two folding screens: one for the operator to view, and the other facing outward for the consumer to view and confirm information.

[0003] Currently available split-screen display devices for laptops, when in use, mostly use an external screen in conjunction with a clamping mechanism, and the external screen is clipped onto one side of the laptop main screen. However, there are certain defects in actual use. The clamping mechanism fixes the external screen by connecting with the four corners of the laptop main screen, and the positions of the clamping mechanism and the external screen are fixed. The fixed clamping position limits the user's freedom to adjust the position of the external screen, making it difficult to meet the needs of different operating habits. Therefore, it is necessary to redesign a split-screen display device for a laptop computer to address the above problems. Utility Model Content

[0007] Preferably, the connecting mechanism comprises two groups of connecting rods fixedly connected to the outer wall of the slider, the positions of the two groups of connecting rods are symmetrical to each other, and the ends of the two groups of connecting rods are fixedly connected to the piston.

[0010] Preferably, the end of the threaded rod is fixedly connected to a limiting block, and the radius of the limiting block is larger than the radius of the threaded rod.

[0011] Preferably, the outer wall of the device barrel is rotatably connected to a rotating block, and the rotating block is coaxially and fixedly connected to the threaded rod.

[0012] Preferably, a support groove is provided on the outer wall of the bracket, a support plate is rotatably connected in the support groove, and an anti-slip pad is provided at the end of the support plate.

[0015] The utility model has the following beneficial effects:

[0016] 1.

The device cylinder 8 is communicated with the interior of the two groups of suction cups 3. A piston 15 and a slider 14 are slidably connected in the device cylinder 8. The slider 14 is connected to the piston 15 through a connecting mechanism. A sliding mechanism for driving the slider 14 and the piston 15 to slide is installed in the device cylinder 8; the bracket 1 and the external split screen 2 are connected to the back of the laptop screen through the suction cup 3, and the position of the external split screen 2 can be flexibly adjusted according to specific usage needs.

[0025] The connecting mechanism includes two groups of connecting rods 11 fixedly connected to the outer wall of the slider 14. The positions of the two groups of connecting rods 11 are symmetrical to each other. The ends of the two groups of connecting rods 11 are fixedly connected to the piston 15. The sliding mechanism includes a threaded rod 10 rotatably connected to the inner wall of the device tube 8. The slider 14 is threadedly connected to the threaded section of the threaded rod 10. With the help of the rotation of the threaded rod 10, negative pressure can be formed in the suction cup 3, and then it fits tightly to the back of the notebook screen. The set threaded rod 10 has good self-locking properties, thereby ensuring stability after adsorption.

Rotating the rotating block 9 will drive the threaded rod 10 to rotate. As the threaded rod 10 rotates, the slider 14 threadedly connected to the threaded rod 10 will slide along the limit rod 13, driving the piston 15 to slide in the device tube 8.
