Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0016] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0017] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a support and protection device for a folding screen, including multiple display screens 1. The display screens 1 are arranged in close contact with each other. Each display screen 1 is covered with an outer cover. One side of each outer cover protrudes to form a connecting part 19. The outer side of each connecting part 19 forms an arc-shaped surface. A fixing post 14 is provided in the arc-shaped surface of the connecting part 19. Each fixing post 14 is provided with multiple annular connecting grooves 15. Each arc-shaped surface is provided with a connecting block 18. The connecting block 18 is slidably disposed in the connecting groove 15. A shaft 12 is installed at both ends of each fixing post 14. A support plate 5 is installed on the outside of each shaft 12 through a bearing. A base plate 6 is installed at one end of the support plate 5. A counterweight 7 is installed on the base plate 6. An insertion mechanism for positioning the shaft 12 is installed on the outer side of each support plate 5.

[0019] In this embodiment, the inner ring surface of the connecting groove 15 is provided with a plurality of grooves in an annular structure. A ball 16 is provided in the opening of each groove. A first compression spring 20 is installed at one end of each ball 16 located inside the groove. The other end of each first compression spring 20 is installed on the inner wall surface of the groove. A plurality of ball grooves are provided on the inner side surface of the connecting block 18. The balls 16 opposite to the ball grooves are inserted into the ball grooves.

[0020] In this embodiment, both sides of the connecting groove 15 are provided with annular sliding grooves 17, and both sides of the connecting block 18 protrude to form sliders. The sliders are slidably disposed in the sliding grooves 17, and rubber layers are installed on the inner wall surface of the sliding grooves 17. The sliders are in frictional contact with the rubber layers. The sliding groove can confine the connecting block within the connecting groove, preventing it from detaching from the groove.

[0021] In this embodiment, the insertion mechanism includes a plug rod 11, a grip rod 10, a second compression spring 9, and a positioning block. The outer side of the support plate 5 is provided with a positioning groove 8. The positioning blocks are slidably disposed in the positioning groove 8. The plug rod 11 and the grip rod 10 are installed on the outer side of the positioning block. The outer ring surface of the shaft 12 is provided with a plurality of slots 13 in an annular structure. The other end of the plug rod 11 is inserted into the slot 13. The second compression spring 9 is installed between the positioning block and the positioning groove 8.

[0022] In this embodiment, both the positioning block and the positioning groove 8 have trapezoidal cross-sections, which allows the positioning block to move up and down along the positioning groove, thus preventing it from detaching from the positioning groove.

[0023] In this embodiment, both sides of the display screen 1 are provided with limiting grooves, the cover 2 is set in a "U" shape, both sides of the cover 2 protrude to form limiting strips 3, the limiting strips 3 are slidably set in the limiting grooves, and one side of the cover 2 is threaded with a fixing bolt 4 that connects the cover 2 and the display screen 1 together. After unscrewing the fixing bolts, the display screen can be directly removed from the housing along the limiting strip, which facilitates the replacement of the display screen. The limiting groove is designed to avoid the internal electrical components.

[0024] In this embodiment, the length of the support plate 5 is longer than the width of the display screen 1, so that the display screen and the cover can be smoothly rotated to the inside of the support plate.

[0025] Working principle: as shown in the appendix Figure 4 As shown, during use, the cover and display screen can be directly pushed. The rotation of the cover drives the connecting block, causing the connecting block to move in a circle along the connecting groove and slide, so that the display screen can be opened smoothly. Since there is a ball on the inner ring surface of the connecting groove, after the display screen moves to a suitable angle, the ball can be inserted into the ball groove of the connecting groove by the rebound of the first compression spring. And through the damping effect between the slider and the rubber layer, the display screen opened to different angles can be positioned. After pushing the positioning block downwards with the lever, the insertion rod can be moved out of the slot. At this time, the fixed shaft can drive the two displays to rotate synchronously, which allows the overall angle to be adjusted and increases adaptability.

[0026] As attached Figure 5As shown, when not in use, the display screen can be moved inward along the connecting groove and the screens can be set relatively close together to avoid the screen being impacted by the outside. Combined with the cover, the safety is increased. After the display screens are attached, the fixing post can be loosened again, allowing the two display screens to rotate between the support plate, which greatly reduces the area occupied on the desktop and the space above the desktop and increases adaptability.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
