The lifting mechanism is fixedly connected to a display screen support frame and drives it to move up and down. The display screen support frame is connected to the folding mechanism, and several display screens are fixedly mounted on the support frame. The support frame is expanded or retracted by the folding mechanism. This allows the display screens to expand and support the display screen support frame for normal operation during use, and to fold and retract them to prevent damage when storage or transportation is required. Furthermore, the process of expanding and retracting is convenient and quick.

[0017] The sliding rail folding screen device of the present invention has the following advantages compared with the prior art:

[0018] 1. By fixing two guide seats to both sides of the first support frame, and two guide rods to the two guide seats respectively, and connecting the two guide rods to the first display screen, the first support frame is engaged with the first display screen through the guide seats and guide rods. This allows the first support frame to rotate, driving the first display screen to rotate via the guide rods. Simultaneously, the guide rods can move up and down within the guide seats, adjusting the distance between the first display screen and the first support frame, so that the second display screen is positioned between the first support frame and the first display screen. By allowing the moving rails to move within the first groove of the slide block, two second support frames are connected to the two moving rails respectively, and the second display screen is simultaneously fixed to the two second support frames. This allows the moving rails to extend outwards from the slide block or be concealed within it, enabling the two second support frames to be positioned on either side of the first support frame, with the second display screen positioned between the first display screen and the first support frame, reducing the space occupied by the product. Furthermore, positioning the second support frames outside the first support frame allows the second display panel and the first display screen placed on the first support frame to form a unified whole, allowing the product to unfold and increasing its display area. Furthermore, since the third support frame can rotate relative to the first support frame, the third display screen can also rotate relative to the first display screen. This allows the third display screen to be at a 90-degree angle to the first display screen when it is vertical, further reducing the space occupied by the product. Simultaneously, when the third display screen is horizontal, it is on the same plane as the first display screen, thus increasing the display area of ​​the product. By placing the second display screen between the first display screen and the first support frame, the thinness of both the first and second display screens is utilized to fully leverage vertical space. Compared to rotating and folding the first and second display screens, the product occupies less height, thus reducing the product's space requirements. At the same time, the first and second display screens have sufficient length, allowing the product to have a larger display area when unfolded, further enhancing the user experience.

[0019] 2. When the first support frame is placed on the upright beam and is perpendicular to the upright beam, the connecting rod is at a predetermined angle to the second connecting frame and the third connecting frame. When the lifting mechanism moves the first support frame upward through the lifting frame and the connecting column, since the length of the connecting rod does not change, the connecting rod will drive the third connecting frame and the first support frame to rotate downward, thereby making the first display screen, the second display screen and the third display screen vertical. This achieves the goal of automatically flipping the first display screen, the second display screen and the third display screen from a horizontal state to a vertical state without manually rotating the first support frame, thus improving the user experience of the product.

[0020] 3. By fixing the lifting seat to the lifting frame and passing the lead screw through the first threaded hole of the lifting seat, the lifting seat and the lifting frame can move up and down synchronously, thereby realizing the threaded connection between the lead screw and the lifting seat, and then rotating the lead screw to drive the lifting seat and the lifting frame to move up and down, so as to adjust the height of the lifting frame.

[0021] 4. By fixing two sliders to the lifting frame and two slide rails to the vertical beam, and by having the two slide rails pass through the second slide grooves of the two sliders respectively, the vertical beam supports the two slide rails, thereby enabling the lifting frame to move up and down along the slide rails via the sliders, thus preventing the lifting frame from deviating during up and down movement and improving the stability of the lifting frame's up and down movement.

[0022] 5. By connecting the first rotating seat to the first mounting component and the second rotating seat to the second mounting component, the first mounting component supports the first rotating seat, and simultaneously, the second mounting component supports the second rotating seat. By embedding the second rotating seat into the first connecting groove of the first rotating seat and passing the connecting shaft through the first and second rotating seats in sequence, the first and second rotating seats are connected together via the connecting shaft, allowing the first and second rotating seats to rotate relative to each other, and consequently, allowing the first support frame and the third support frame to rotate relative to each other. By fitting two limiting nuts onto the outside of the connecting shaft, embedding the two limiting nuts into the first rotating seat, and abutting the two limiting nuts against the two sides of the second rotating seat, the two limiting nuts are threadedly connected to the connecting shaft, thereby limiting the second rotating seat and preventing displacement along the axis of the connecting shaft, thus improving the stability of the relative rotation between the third support frame and the first support frame.

[0023] 6. By making the first mounting component and the first rotating seat an integral structure, the first mounting component and the first rotating seat can be machined in one step, thereby improving the connection strength between the first mounting component and the first rotating seat and reducing the difficulty of machining the first mounting component and the first rotating seat, thus improving the user experience of the product. Similarly, by making the second mounting component and the second rotating seat an integral structure, the second mounting component and the second rotating seat can be machined in one step, thereby improving the connection strength between the second mounting component and the second rotating seat and reducing the difficulty of machining the second mounting component and the second rotating seat, thus improving the user experience of the product.

[0024] 7. When the first display screen moves upward and there is a gap between the first display screen and the first support frame, rotate the rotating plate to unfold it; then, connect one end of the support rod to the rotating plate and place the receiving frame on top of the two support rods; next, embed the support pad into the receiving groove of the receiving frame, pass the fixing pin through the receiving frame and the support pad in sequence, and connect the fixing pin to the support rod to connect the support rod and the receiving frame together, and fix the support pad in the receiving frame; then, place the first display screen on the support pad to realize that the support pad supports the first display screen, thereby improving the stability of the first display screen, and at the same time, ensuring that there is a gap between the first display screen and the first support frame so that the second display screen can be located between the first display screen and the first support frame.

[0025] 8. By passing the first locking rod through the third threaded hole of the first locking seat and embedding at least a portion of the first locking rod into the first snap-fit ​​hole of the first snap-fit ​​seat, the first locking rod and the first locking seat are threadedly connected. This allows the first locking rod to be screwed on, causing it to extend from the first locking seat and embed into the first snap-fit ​​hole, thereby connecting the first snap-fit ​​seat and the first locking seat together. By passing the first locking plate through the side wall of the first locking seat and embedding it into the first locking rod, the first locking plate fixes the first locking rod within the first locking seat, thereby improving the robustness of the connection between the first locking seat and the first snap-fit ​​seat, and consequently improving the robustness of the connection between the first display screen and the second display screen. By passing the first set screw through the top of the first locking seat and abutting it against the first locking rod, the first set screw fixes the first locking rod within the first locking seat, preventing movement of the first locking rod within the first locking seat and thus improving the stability of the first locking rod.

[0026] 9. By passing the second locking rod through the fourth threaded hole of the second locking seat and embedding at least a portion of the second locking rod into the second snap-fit ​​hole of the second snap-fit ​​seat, the second locking rod and the second locking seat are threadedly connected. This allows the second locking rod to be screwed on, causing it to extend from the second locking seat and embed into the second snap-fit ​​hole, thereby connecting the second snap-fit ​​seat and the second locking seat together. By passing the second locking plate through the side wall of the second locking seat and embedding it into the second locking rod, the second locking plate fixes the second locking rod within the second locking seat, thereby improving the robustness of the connection between the second locking seat and the second snap-fit ​​seat, and thus improving the robustness of the connection between the first display screen and the third display screen. By passing the second set screw through the top of the second locking seat and abutting it against the second locking rod, the second set screw fixes the second locking rod within the second locking seat, preventing movement of the second locking rod within the second locking seat and thus improving the stability of the second locking rod.

[0027] 10. By setting multiple first positioning holes at one end of the first display screen and multiple first positioning pins at one end of the third display screen, with the first positioning pins facing the first positioning holes, the first positioning pins can be inserted into the first positioning holes when the third display screen rotates and is on the same plane as the first display screen. This facilitates the insertion of the second locking rod into the second snap-fit ​​hole, thereby improving the user experience. Similarly, by setting multiple second positioning holes at the other end of the first display screen and multiple second positioning pins at one end of the second display screen, with the second positioning pins facing the second positioning holes, the second positioning pins can be inserted into the second positioning holes when the second display screen moves and is in contact with the first display screen. This facilitates the insertion of the first locking rod into the first snap-fit ​​hole, further improving the user experience. Attached Figure Description

Detailed Implementation

[0041] The following are specific implementation cases and appendices. Figures 1 to 11 The present invention will be further described, but the present invention is not limited to these embodiments.

[0042] A sliding rail folding screen device, such as Figures 1 to 11As shown, the sliding rail folding screen device includes: a base 10, a vertical beam 11, a lifting mechanism 12, a lifting frame 13, a first connecting frame 14, a connecting column 15, a first support frame 16, a first display screen 17, a guide seat 18, a guide rod 19, a slide seat 20, a moving rail 22, a second support frame 23, a second display screen 24, a rotating connector 25, a third support frame 26, and a third display screen 27; the vertical beam 11 is fixed on the base 10 and is perpendicular to the base 10; the lifting mechanism 12 is installed on the side wall of the vertical beam 11; the lifting frame 13 is connected to the lifting mechanism 12; two first connecting frames 14 are fixed on the lifting frame 13, and there is a gap between the two first connecting frames 14; one end of the connecting column 15 is located between the two first connecting frames 14, and the connecting column 15 is rotatably connected to both first connecting frames 14; the first support frame 16 is placed on top of the vertical beam 11, and The first support frame 16 is fixedly connected to the connecting column 15; the first display screen 17 is located above the first support frame 16; two guide seats 18 are fixed on both sides of the first support frame 16; two guide rods 19 pass through the two guide seats 18 respectively, and the two guide rods 19 are simultaneously connected to the first display screen 17; a first sliding groove 21 is provided in the slide seat 20, and the two slide seats 20 are respectively fixed on both sides of the first support frame 16; two moving rails 22 are respectively embedded in the two first sliding grooves 21; the second support frame 23 is L-shaped, and the two second support frames 23 are respectively connected to the two moving rails 22; the second display screen 24 is simultaneously fixed on the two second support frames 23; one end of the two rotating connectors 25 is connected to the end of the first support frame 16; the third support frame 26 is simultaneously connected to the other end of the two rotating connectors 25; the third display screen 27 is fixed on the third support frame 26.

[0043] By fixing the upright beam 11 to the base 10, installing the lifting mechanism 12 on the side wall of the upright beam 11, and connecting the lifting frame 13 to the lifting mechanism 12, the upright beam 11 supports the lifting mechanism 12, thereby enabling the lifting mechanism 12 to drive the lifting frame 13 to move up and down, thus adjusting the height of the lifting frame 13. By fixing two first connecting frames 14 to the lifting frame 13, placing one end of the connecting column 15 between the two first connecting frames 14, and rotatably connecting the connecting column 15 to both first connecting frames 14, the connecting column 15 can rotate relative to the two first connecting frames 14, thereby enabling the two first connecting frames 14 to drive the connecting column 15 to move up and down. At the same time, by fixing the first support frame 16 to the connecting column 15 and placing the first support frame 16 on top of the upright beam 11, the connecting column 15 and the first support frame 16 can move and rotate synchronously, and the upright beam 11 can also support the first support frame 16. By fixing two guide seats 18 to both sides of the first support frame 16, passing two guide rods 19 through the two guide seats 18 respectively, and connecting the two guide rods 19 to the first display screen 17 at the same time, the first display screen 17 is engaged with the first support frame 16 through the guide rods 19 and the guide seats 18, so that the first support frame 16 can drive the first display screen 17 to rotate. At the same time, when the guide rods 19 move up and down in the guide seats 18, the distance between the first display screen 17 and the first support frame 16 can be adjusted. By fixing two slide blocks 20 to both sides of the first support frame 16 and embedding two moving rails 22 into the two first sliding grooves 21, the first support frame 16 supports the two slide blocks 20, thereby enabling the moving rails 22 to move within the first sliding grooves 21. This allows the moving rails 22 to extend out of the outside of the slide blocks 20 or be hidden inside the slide blocks 20. By connecting two L-shaped second support frames 23 to the two moving rails 22 and fixing the second display screen 24 to the two second support frames 23, the two second support frames 23 support the second display screen 24, thereby enabling the second display screen 24, the two second support frames 23, and the two moving rails 22 to move synchronously, thereby adjusting the relative position of the second display screen 24 and the first display screen 17. By connecting one end of the two rotating connectors 25 to the end of the first support frame 16, and simultaneously connecting the third support frame 26 to the other end of the two rotating connectors 25, the third support frame 26 and the first support frame 16 can rotate relative to each other; at the same time, by fixing the third display screen 27 to the third support frame 26, the third support frame 26 supports the third display screen 27, thereby enabling the third support frame 26 and the third display screen 27 to rotate synchronously.

[0044] When the product is not in use, the moving rail 22 is fully embedded in the first slide groove 21, and the two L-shaped second support frames 23 are located on both sides of the first support frame 16. The second display screen 24 is placed on the first support frame 16, and the first display screen 17 is a certain distance away from the first support frame 16 and is located above the second display screen 24. At this time, the third support frame 26 is in a vertical state and is at a 90-degree angle to the first support frame 16. Therefore, the third display screen 27 is at a 90-degree angle to the first display screen 17, thereby reducing the space occupied by the product.

[0045] When using the product, first pull the two second support frames 23 outwards to move the second display screen 24 off the first support frame 16; then, push the first display screen 17 downwards to move the guide rod 19 downwards within the guide seat 18, thereby placing the first display screen 17 on the first support frame 16 and bringing the end of the first display screen 17 into contact with the end of the second display screen 24, at which point the first display screen 17 and the second display screen 24 are on the same plane; then, rotate the third support frame 26 to make it horizontal, thereby bringing the third display screen 27 on the same plane as the first display screen 17, thus making the first display screen 17, the second display screen 24 and the third display screen 27 form a whole display screen, so that the product is in an unfolded state, making it convenient for staff to use the product as a sand table.

[0046] When preparing to flip the product, the lifting mechanism 12 is activated, causing the lifting frame 13 to move upward. This allows the lifting frame 13 to move the first support frame 16 upward via the connecting column 15, thereby increasing the distance between the first display screen 17, the second display screen 24, and the third display screen 27 and the base 10. This provides sufficient space for the first display screen 17, the second display screen 24, and the third display screen 27 to flip. Then, the first support frame 16 is rotated, causing it to rotate 90 degrees relative to the lifting frame 13 via the connecting column 15. This brings the first display screen 17, the second display screen 24, and the third display screen 27 into a vertical position, making it easier for workers to use the product as a display screen.

[0047] With the above structure, by fixing two guide seats 18 to both sides of the first support frame 16, and by connecting two guide rods 19 to the two guide seats 18 respectively, the first support frame 16 is engaged with the first display screen 17 through the guide seats 18 and the guide rods 19. Thus, when the first support frame 16 rotates, the first support frame 16 drives the first display screen 17 to rotate through the guide rods 19. At the same time, the guide rods 19 can also move up and down within the guide seats 18, thereby adjusting the distance between the first display screen 17 and the first support frame 16, so that the second display screen 24 is located between the first support frame 16 and the first display screen 17. By allowing the moving rail 22 to move within the first groove 21 in the slide block 20, the two second support frames 23 are connected to the two moving rails 22 respectively, and the second display screen 24 is simultaneously fixed on the two second support frames 23. This allows the moving rail 22 to extend out of the outside of the slide block 20 or be hidden inside the slide block 20, thereby positioning the two second support frames 23 on both sides of the first support frame 16 and positioning the second display screen 24 between the first display screen 17 and the first support frame 16, thus reducing the space occupied by the product. At the same time, it also allows the second support frame 23 to be positioned outside the first support frame 16, thereby enabling the second display panel and the first display screen 17 placed on the first support frame 16 to form a whole, allowing the product to unfold and increasing the display area of ​​the product. Furthermore, since the third support frame 26 and the first support frame 16 can rotate relative to each other, the third display screen 27 and the first display screen 17 can also rotate relative to each other. This allows the third display screen 27 to be at a 90-degree angle to the first display screen 17 when it is in a vertical position, further reducing the space occupied by the product. Simultaneously, when the third display screen 27 is in a horizontal position, it is on the same plane as the first display screen 17, thereby increasing the display area of ​​the product. By placing the second display screen 24 between the first display screen 17 and the first support frame 16, the thinness of the first and second display screens 17 and 24 is utilized to fully leverage the vertical space. Compared to rotating and folding the first and second display screens 17 and 24, the product occupies less height, thus reducing the product's space requirements. At the same time, the first and second display screens 17 and 24 have sufficient length, allowing the product to have a larger display area when unfolded, further enhancing the user experience.

[0048] In embodiments of the present invention, such as Figures 1 to 11As shown, the sliding rail folding screen device also includes: a second connecting frame 28, connecting rods 29 and a third connecting frame 30; the second connecting frame 28 is fixed on the base 10; one end of each of the two connecting rods 29 is rotatably connected to the two sides of the second connecting frame 28 respectively; the third connecting frame 30 is fixed to the bottom of the first support frame 16, the third connecting frame 30 is perpendicular to the first support frame 16, and the third connecting frame 30 is rotatably connected to the other end of each of the two connecting rods 29.

[0049] By fixing the second connecting frame 28 to the base 10, one end of each of the two connecting rods 29 is rotatably connected to the two sides of the second connecting frame 28, so that the two connecting rods 29 can rotate relative to the second connecting frame 28; by fixing the third connecting frame 30 to the bottom of the first support frame 16, and simultaneously rotatably connecting the third connecting frame 30 to the two connecting rods 29, so that the two connecting rods 29 and the third connecting frame 30 can rotate relative to each other.

[0050] With the above structure, when the first support frame 16 is placed on the upright beam 11 and is perpendicular to the upright beam 11, the connecting rod 29 is at a predetermined angle to the second connecting frame 28 and the third connecting frame 30. When the lifting mechanism 12 drives the first support frame 16 to move upward through the lifting frame 13 and the connecting column 15, since the length of the connecting rod 29 does not change, the connecting rod 29 will drive the third connecting frame 30 and the first support frame 16 to rotate downward, thereby making the first display screen 17, the second display screen 24 and the third display screen 27 in a vertical state. This achieves the goal of automatically flipping the first display screen 17, the second display screen 24 and the third display screen 27 from a horizontal state to a vertical state without manually rotating the first support frame 16, thus improving the user experience of the product.

[0051] In embodiments of the present invention, such as Figures 1 to 11 As shown, the lifting mechanism 12 includes: a mounting plate 121, a lead screw 122, and a lifting seat 123; two mounting plates 121 are fixed on the upright beam 11, and there is a gap between the two mounting plates 121; a first external thread is provided on the outer wall of the lead screw 122, and the two ends of the lead screw 122 are rotatably connected to the two mounting plates 121 respectively; a first threaded hole is provided in the lifting seat 123, and a first internal thread is provided in the first threaded hole; the lifting seat 123 is fixed on the lifting frame 13, and the lifting seat 123 is located between two first connecting frames 14, and the lead screw 122 passes through the first threaded hole of the lifting seat 123; wherein, the first external thread and the first internal thread are adapted to each other.

[0052] By fixing two mounting plates 121 to the upright beam 11 and rotatably connecting the two ends of the lead screw 122 to the two mounting plates 121 respectively, the two mounting plates 121 cooperate to support the lead screw 122, thereby enabling the lead screw 122 to rotate between the two mounting plates 121. By fixing the lifting seat 123 to the lifting frame 13 and passing the lead screw 122 through the first threaded hole of the lifting seat 123, the lifting seat 123 and the lifting frame 13 move up and down synchronously, thereby achieving a threaded connection between the lead screw 122 and the lifting seat 123. This allows the lead screw 122 to be rotated, causing the lead screw 122 to drive the lifting seat 123 and the lifting frame 13 to move up and down, thereby adjusting the height of the lifting frame 13.

[0053] In embodiments of the present invention, such as Figures 1 to 11 As shown, the lifting mechanism 12 also includes: a motor 124, a slider 125, and a slide rail 126; the motor 124 is provided with an output shaft, the motor 124 is fixed on the upright beam 11, and the output shaft of the motor 124 is connected to the lead screw 122; the slider 125 is provided with a second slide groove, and the two sliders 125 are fixed on the lifting frame 13; the two slide rails 126 are fixed on the upright beam 11, and the two slide rails 126 pass through the second slide grooves of the two sliders 125 respectively.

[0054] By fixing the motor 124 to the upright beam 11 and connecting the output shaft of the motor 124 to the lead screw 122, the upright beam 11 supports the motor 124, enabling the motor 124 to drive the lead screw 122 to rotate, thereby providing power for rotating the lead screw 122. By fixing two sliders 125 to the lifting frame 13 and two slide rails 126 to the upright beam 11, and allowing the two slide rails 126 to pass through the second slide grooves of the two sliders 125 respectively, the upright beam 11 supports the two slide rails 126, enabling the lifting frame 13 to move up and down along the slide rails 126 via the sliders 125, thus preventing the lifting frame 13 from deviating during up and down movement and improving the stability of the lifting frame 13's up and down movement.

[0055] In embodiments of the present invention, such as Figures 1 to 11As shown, the rotating connector 25 includes: a first mounting member 251, a first rotating seat 252, a second mounting member 253, a second rotating seat 254, a connecting shaft 255, and a limiting nut 256; the first mounting member 251 is L-shaped, the end of the first support frame 16 is embedded in the first mounting member 251, and the first mounting member is connected to the first support frame 16; the first rotating seat 252 is provided with a first connecting groove, and the first rotating seat 252 is connected to the first mounting member 251; the second mounting member 253 is L-shaped, the end of the third support frame 26 is embedded in the second mounting member 253, and the second mounting member 253 is connected to the third support frame 26; The second rotating seat 254 is connected to the second mounting part 253, and at least part of the second rotating seat 254 is embedded in the first connecting groove; the outer wall of the connecting shaft 255 is provided with a second external thread, and the connecting shaft 255 passes through the first rotating seat 252 and the second rotating seat 254 in sequence; the limiting nut 256 is provided with a second threaded hole, and the second threaded hole is provided with a second internal thread, the two limiting nuts 256 are fitted on the outside of the connecting shaft 255, the two limiting nuts 256 are embedded in the first rotating seat 252, and the two limiting nuts 256 are respectively in contact with the two sides of the second rotating seat 254; wherein, the second external thread is adapted to the second internal thread.

[0056] By embedding the end of the first support frame 16 into the L-shaped first mounting member 251 and connecting the first mounting member 251 to the first support frame 16, the first mounting member 251 wraps around the end of the first support frame 16, thereby increasing the contact area between the first mounting member and the first support frame 16 and thus improving the firmness of the connection between the first mounting member 251 and the first support frame 16. Similarly, by embedding the end of the third support frame 26 into the L-shaped second mounting member 253 and connecting the second mounting member 253 to the third support frame 26, the second mounting member 253 wraps around the end of the third support frame 26, thereby increasing the contact area between the second mounting member and the third support frame 26 and thus improving the firmness of the connection between the second mounting member 253 and the third support frame 26.

By embedding the second rotating seat 254 into the first connecting groove of the first rotating seat 252 and passing the connecting shaft 255 through the first rotating seat 252 and the second rotating seat 254 in sequence, the first rotating seat 252 and the second rotating seat 254 are connected together by the connecting shaft 255, so that the first rotating seat 252 and the second rotating seat 254 can rotate relative to each other, and thus the first support frame 16 and the third support frame 26 can rotate relative to each other. By fitting two limiting nuts 256 onto the outside of the connecting shaft 255, embedding the two limiting nuts 256 into the first rotating seat 252, and respectively abutting the two limiting nuts 256 against the two sides of the second rotating seat 254, the two limiting nuts 256 are threadedly connected to the connecting shaft 255. This allows the two limiting nuts 256 to limit the second rotating seat 254, preventing the second rotating seat 254 from shifting along the axis of the connecting shaft 255, thereby improving the stability of the relative rotation between the third support frame 26 and the first support frame 16.
