DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.
[0025] Embodiment 1: A folding mechanism for a folding screen, as Figures 1-4 shown, includes a rotating column 1, a fixed ring 2 installed on the outer side of the rotating column 1, and a support block 4. The fixed ring 2 is fixedly connected to the rotating column 1, the support block 4 is rotatably connected to the rotating column 1. Rotating rings 12 are installed on the surfaces of opposite ends of the rotating column 1. At least two arc-shaped support grooves 13 are formed on the outer side of the rotating ring 12. A guide rod 11 is inserted into the rotating ring 12. A pressing disc 9 is installed at the outer end of the guide rod 11. A rotating support column 7 is inserted into the pressing disc 9. The rotating support column 7 is rotatably connected to the rotating column 1.
[0026] When the device operates, by pressing the pressing discs 9 on both sides, the guide rods 11 on both sides are driven to slide from the higher end of the inner wall of the arc-shaped support groove 13 to its lower end. Based on the pressing limit of the pressing disc 9 and the rotational connection between the rotating support column 7 and the rotating column 1, when the guide rod 11 is gradually pressed against the arc-shaped support groove 13, the rotating ring 12 is driven to rotate passively, so as to achieve the effect of rotating the rotating column 1. At the same time, with the rotational support of the support block 4, the fixed ring 2 rotates simultaneously with the rotating column 1. Thus, by pressing the pressing discs 9 on both sides, the effect of simultaneously rotating the fixed ring 2 and the screen on one side thereof is achieved, without the need for manual flipping of the screen by humans, improving the convenience and experience of using the device.
[0027] As Figures 1-4 shown, a sliding groove 10 is formed inside the pressing disc 9. The rotating support column 7 extends into the sliding groove 10.
[0028] A limiting rod 8 is installed on the outer side of the rotating support column 7. The limiting rod 8 is located inside the sliding groove 10.
[0029] When pressing the pressing disc 9, the rotating support column 7 will move simultaneously inside the sliding groove 10. With the separate limit support for the limit rod 8 on both sides of the sliding groove 10, the stability of the rotation of the rotating support column 7 and the rotating column 1 is ensured, and the rotating support column 7 is limited in telescoping inside the pressing disc 9 to ensure the accurate movement of the pressing disc 9 and the accurate rotation of the rotating column 1.
[0030] As Figures 1-4 shown, a telescopic spring 14 is installed outside the rotating column 1. The telescopic spring 14 is located outside the rotating support column 7, and the end of the telescopic spring 14 away from the rotating column 1 is installed on the inner surface of the pressing disc 9.
[0031] When the pressing disc 9 is pressed, the telescopic spring 14 will contract simultaneously. When the pressing on the pressing disc 9 is released, under the elastic support of itself, the telescopic spring 14 will automatically reset and rebound, driving the pressing disc 9 to automatically reset, and both pressing discs 9 are installed on the side of the device to ensure the convenience and handiness of pressing the pressing disc 9.
[0032] Embodiment 2: A folding mechanism for a folding screen, as Figures 1-4 shown, there are at least two rotating rings 12 and pressing discs 9, and the two pressing discs 9 and the rotating rings 12 are located at opposite ends of the rotating column 1.
[0033] By pressing the two pressing discs 9 simultaneously, the pressure on the rotation of the rotating column 1 is increased, thereby ensuring the potential energy of the rotation of the rotating column 1, so that the rotating column 1 can still move after the pressing disc 9 is reset, ensuring the accurate and automatic movement position of the screen.
[0034] As Figures 1-4 shown, a number of fixing rings 2 are installed outside the rotating column 1, a connecting rod 3 is installed outside the fixing ring 2, and one end of a number of connecting rods 3 is simultaneously installed and connected to a movable screen 5.
[0035] There are a number of support blocks 4, and a number of support blocks 4 are simultaneously connected to a fixed screen 6, and the fixed screen 6 is located below the movable screen 5.
[0036] By holding the fixed screen 6, with the connection and support of the fixed screen 6 and the support blocks 4, the accuracy of the rotation of the rotating column 1 is ensured, so that the connecting rod 3 rotates simultaneously with the fixing ring 2. Under the connection of the connecting rod 3, the rotation of the movable screen 5 is ensured to be simultaneous and accurate.
[0037] Working principle: Hold the fixed screen 6 by hand, then press the pressing disks 9 on both sides, driving the guide rods 11 on both sides to slide from the higher end of the inner wall of the arc-shaped support groove 13 to its lower end. Based on the pressing limit of the pressing disk 9 and the rotational connection between the rotating support column 7 and the rotating column 1, when the guide rod 11 presses on the arc-shaped support groove 13, the rotating ring 12 is driven to rotate passively, thus achieving the effect of rotating the rotating column 1. At the same time, under the rotational support of the support block 4, the fixed ring 2 rotates simultaneously with the rotating column 1. Under the connection of the connecting rod 3, it is ensured that the moving screen 5 rotates accurately while rotating, eliminating the need for manual flipping of the screen by users, improving the convenience and user experience of the device.
[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
