[0013] Furthermore, the guiding device also includes a first adjusting component, which is connected to the guide frame and the first guide wheel respectively. The first adjusting component is capable of adjusting the horizontal distance or vertical height of the first guide wheel.

[0014] Furthermore, the first adjustment assembly includes a first telescopic rod, a second telescopic rod, and a first fastener. The first telescopic rod is connected to the guide frame. The first telescopic rod and the second telescopic rod are arranged in a vertical direction. The second telescopic rod is telescopically disposed inside the first telescopic rod. One end of the second telescopic rod is connected to the first guide wheel.

[0015] The first telescopic rod is provided with a plurality of first mounting holes spaced apart along the axial direction, and the second telescopic rod is provided with a plurality of second mounting holes spaced apart along the axial direction. The second mounting holes are adapted to the first mounting holes. The first fastener can be inserted through the first mounting holes and the second mounting holes to restrict the extension and retraction of the second telescopic rod relative to the first telescopic rod, thereby adjusting the vertical height of the first guide wheel.

[0016] Furthermore, the first adjustment component includes a first slider, a first connector, and a second fastener. The first connector is connected to the end of the second telescopic rod away from the first telescopic rod, and the first slider is capable of sliding relative to the first connector in a horizontal direction.

[0017] The first sliding member has a plurality of third mounting holes spaced apart along the axial direction, and the first connecting member has a fourth mounting hole. The third mounting holes and the fourth mounting holes are adapted to each other. The second fastener passes through the third mounting holes and the fourth mounting holes to restrict the sliding of the first sliding member relative to the first connecting member, thereby adjusting the horizontal distance of the first guide wheel.

[0018] Furthermore, the guiding device also includes a second adjustment component, which is connected to the guide frame and the second guide wheel respectively. The second adjustment component is capable of adjusting the horizontal distance or vertical height of the second guide wheel.

[0019] Furthermore, multiple traction ropes and multiple counterweights are provided, with each traction rope and multiple counterweights corresponding to the other.

[0020] The plurality of traction ropes and the plurality of counterweights are spaced apart along the axial direction of the guide frame.

[0021] Furthermore, the guide frame includes a first sidewall and a second sidewall disposed opposite to each other. The first sidewall extends in a direction away from the second sidewall and has an extension portion.

[0044] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments, a display device includes a folding screen guide device 10 and a folding screen 20. The folding screen 20 includes a plurality of screen units arranged in a vertical direction. Two adjacent screen units are flexibly connected, and the plurality of screen units can be folded and stored in the guide device 10.

[0046] When the foldable screen 20 is stored, multiple screen units can be bent and folded sequentially, and then stored together in the internal space of the guide device 10, achieving neat storage and positioning of the foldable screen 20. By dividing the foldable screen 20 into multiple vertically arranged and flexibly connected screen units, the large-size screen can be folded and stored in sections, significantly reducing the space occupied after storage. In conjunction with the guide device 10 to complete the folding and storage positioning, it can protect, guide, and constrain the folded screen units, avoiding twisting and damage during the folding process. At the same time, the guide device 10 ensures stable storage and placement, improving the neatness, protection, and overall reliability of the foldable screen 20.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments, a guiding device 10 for a foldable screen 20 includes a guide frame 100, a first fixed pulley 200, a second fixed pulley 300, a traction rope 400, and a counterweight 500. A receiving space is formed within the guide frame 100 for accommodating the foldable screen 20. The first fixed pulley 200 is disposed at the bottom of the guide frame 100. The second fixed pulley 300 is disposed at the top of the guide frame 100. One end of the traction rope 400 is connected to one side of the foldable screen 20, and the traction rope 400 passes around the first fixed pulley 200 and the second fixed pulley 300. The counterweight 500 is connected to the end of the traction rope 400 away from the foldable screen 20.

[0048] During operation, the folding screen 20 is first placed within the receiving space of the guide frame 100, and one side of the folding screen 20 is fixedly connected to the traction rope 400. When raising or lowering the folding screen 20, it moves up and down along the guide frame 100 under external force. The traction rope 400 rolls on the first fixed pulley 200 and the second fixed pulley 300. The counterweight 500 rises and falls synchronously with the traction rope 400, continuously balancing the weight of the folding screen 20 under its own weight, thus maintaining a balanced force on the folding screen 20. The traction rope 400 passes around the first fixed pulley 200 at the bottom of the guide frame 100 and the second fixed pulley 300 at the top of the guide frame 100, forming a gravity-balanced traction mechanism. Under the action of gravity, the counterweight 500 continuously provides a constant balancing pull, which, through the guidance and transmission of the traction rope 400 and the first and second fixed pulleys 200 and 300, counteracts the weight of the folding screen 20, ensuring that the folding screen 20 is in a balanced state of force during rising, falling, and stationary states. This structure eliminates the need for an additional power source, reducing equipment costs and subsequent maintenance costs.

[0049] Please refer to the following: Figure 1 In some embodiments, multiple traction ropes 400 and counterweights 500 are provided, with each traction rope 400 and counterweight 500 corresponding to the other. The multiple traction ropes 400 and counterweights 500 are spaced apart along the axial direction of the guide frame 100.

[0050] It should be noted that, to address the support and balance requirements of the long folding screen 20, multiple traction ropes 400 and counterweights 500 are configured and distributed at intervals along the axial direction of the guide frame 100, with each pair corresponding to a different axial position of the long folding screen 20. Each set of counterweights 500 independently achieves gravitational balance with the traction ropes 400 through the first fixed pulley 200 and the second fixed pulley 300. This achieves multi-point synchronous force application and segmented gravity cancellation across the entire length of the long folding screen 20, resulting in a uniform axial force distribution. This configuration adapts to the lifting and lowering guidance requirements of the long folding screen 20, ensuring balanced force during lifting and lowering, and improving the stability, smoothness, and structural safety of the long folding screen 20.

[0051] In some embodiments, the counterweight 500 may be a counterweight block. More specifically, the counterweight 500 may be a sandbag. More specifically, the weight of the counterweight 500 may be 50 kg.

[0052] In some embodiments, the traction rope 400 may be a steel wire rope. One end of the steel wire rope is fixed to the hardware of the folding screen 20.

[0053] Please refer to the following: Figure 2In some embodiments, the guiding device 10 includes a first guide wheel 610 and a second guide wheel 620. Both the first guide wheel 610 and the second guide wheel 620 are connected to the guide frame 100. The first guide wheel 610 and the second guide wheel 620 are located in the accommodating space and are arranged opposite to each other.

[0054] It should be noted that the first guide wheel 610 and the second guide wheel 620 are positioned opposite each other within the accommodating space of the guide frame 100 and are fixedly connected to the guide frame 100. The first guide wheel 610 and the second guide wheel 620 form a symmetrically distributed rolling constraint interface. During the lifting and lowering process, the folding screen 20 extends into the gap between the first guide wheel 610 and the second guide wheel 620. The first guide wheel 610 and the second guide wheel 620 roll synchronously with the lifting and lowering movement of the folding screen 20, providing continuous lateral limiting and motion guidance for the folding screen 20 through rolling contact. Relying on the symmetrical constraint formed by their relative arrangement and the rolling friction characteristics, the lifting and lowering path of the folding screen 20 is precisely limited. This configuration effectively avoids left and right deviation, swaying, and jamming of the folding screen 20 during lifting and lowering, ensuring a straight and stable lifting trajectory. At the same time, the rolling contact significantly reduces frictional resistance, reduces scratches and wear on the screen surface, protects the screen, improves the smoothness of lifting and lowering, and enhances the overall operational stability and reliability of the guide device 10.

[0055] Please refer to the following: Figure 3 In some embodiments, the guide device 10 further includes a first adjustment component 700. The first adjustment component 700 is connected to the guide frame 100 and the first guide wheel 610 respectively, and the first adjustment component 700 can adjust the horizontal distance or the vertical height of the first guide wheel 610.

[0056] It should be noted that the adjustment of the horizontal distance between the first guide wheel 610 and the first guide wheel 620 by the first adjustment component 700 can change the lateral clamping width between the first guide wheel 610 and the second guide wheel 620, adapting to folding screens 20 of different thicknesses and widths, and ensuring that the first guide wheel 610, the second guide wheel 620 and the folding screen 20 maintain a reasonable fit gap. When the gap is appropriate, it can effectively avoid jamming and friction damage to the folding screen 20 due to too small a gap, or lateral deviation, swaying and tilting of the folding screen 20 during lifting and lowering due to too large a gap, thereby ensuring the stable positioning of the folding screen 20 in the horizontal direction and improving the smoothness and guiding accuracy of the lifting and lowering process.

[0057] In addition, the adjustment of the vertical height of the first guide wheel 610 by the first adjustment component 700 can change the vertical position of the first guide wheel 610 in the accommodating space of the guide frame 100, so that the first guide wheel 610 matches the force area and lifting stroke of the folding screen 20, ensuring that uniform and continuous guiding support can be obtained throughout the lifting range of the folding screen 20.

[0058] Please refer to the following: Figure 3 and Figure 4 In some embodiments, the first adjustment assembly 700 includes a first telescopic rod 710, a second telescopic rod 720, and a first fastener 730. The first telescopic rod 710 is connected to the guide frame 100. The first telescopic rod 710 and the second telescopic rod 720 are arranged vertically. The second telescopic rod 720 is telescopically disposed within the first telescopic rod 710, and one end of the second telescopic rod 720 is connected to the first guide wheel 610. The first telescopic rod 710 is provided with a plurality of first mounting holes 711 spaced apart along the axial direction, and the second telescopic rod 720 is provided with a plurality of second mounting holes 721 spaced apart along the axial direction. The second mounting holes 721 are adapted to the first mounting holes 711. The first fastener 730 can pass through the first mounting holes 711 and the second mounting holes 721 to limit the extension and retraction of the second telescopic rod 720 relative to the first telescopic rod 710, thereby adjusting the vertical height of the first guide wheel 610.

[0059] It should be noted that the first adjustment component 700 achieves vertical height adjustment through a nested telescopic structure of the first telescopic rod 710 and the second telescopic rod 720. The first telescopic rod 710 is fixed to the guide frame 100, and the second telescopic rod 720 can slide vertically up and down within the first telescopic rod 710, driving the first guide wheel 610 to move synchronously. During adjustment, the second telescopic rod 720 is slid to the target height, aligning the second mounting hole 721 with the corresponding first mounting hole 711. Then, the first fastener 730 is inserted and locked in the first mounting hole 711 and the second mounting hole 721. Utilizing the hole fit and the limiting effect of the first fastener 730, the second telescopic rod 720 is restricted from further extension and retraction relative to the first telescopic rod 710, thereby fixing the first guide wheel 610 at the set vertical height position. This telescopic fit and hole locking structure enables multi-level precise adjustment and reliable positioning of the vertical height of the first guide wheel 610, enhancing the versatility and structural reliability of the guide device 10.

[0060] Specifically, the first fastener 730 can be a pin.

[0061] Specifically, the first mounting hole 711 and the second mounting hole 721 can be circular holes.

[0062] In another embodiment, the first telescopic rod 710 and the second telescopic rod 720 can also be telescopically adjusted via a threaded structure.

[0063] Please refer to the following: Figure 3 and Figure 4In some embodiments, the first adjusting assembly 700 includes a first sliding member 740, a first connecting member 750, and a second fastener 760. The first connecting member 750 is connected to the end of the second telescopic rod 720 away from the first telescopic rod 710. The first sliding member 740 is slidable relative to the first connecting member 750 in the horizontal direction. The first sliding member 740 is provided with a plurality of third mounting holes spaced apart in the axial direction. The first connecting member 750 is provided with a fourth mounting hole. The third mounting holes and the fourth mounting holes are adapted to each other. The second fastener 760 passes through the third mounting holes and the fourth mounting holes to restrict the sliding of the first sliding member 740 relative to the first connecting member 750, thereby adjusting the horizontal distance of the first guide wheel 610.

[0064] It should be noted that the first adjustment component 700 achieves lateral spacing adjustment through the horizontal sliding engagement of the first sliding member 740 and the first connecting member 750. The first sliding member 740 can slide horizontally relative to the first connecting member 750, driving the first guide wheel 610 to move synchronously. During adjustment, the first sliding member 740 is slid to the target horizontal position, aligning the third mounting hole on the first sliding member 740 with the fourth mounting hole on the first connecting member 750. Then, the second fastener 760 is inserted and locked into the third and fourth mounting holes. Utilizing the hole alignment and the locking and limiting effect of the second fastener 760, the sliding member 740 is restricted from further sliding relative to the first connecting member 750, thereby fixing the first guide wheel 610 at the set horizontal distance position. This structure enables multi-level precise adjustment and reliable positioning of the horizontal distance of the first guide wheel 610, and can flexibly change the clamping width between the first guide wheel 610 and the second guide wheel 620, adapting to folding screens 20 of different thicknesses and specifications, effectively improving the adaptability, lifting smoothness and structural stability of the guide device 10.

[0065] Specifically, the third and fourth mounting holes can be circular holes.

[0066] Specifically, the second fastener 760 can be a pin.

[0067] Please refer to the following: Figure 3 In some embodiments, the guiding device 10 further includes a second adjusting component 800, which is connected to the guide frame 100 and the second guide wheel 620 respectively. The second adjusting component 800 can adjust the horizontal distance or vertical height of the second guide wheel 620. The second adjusting component 800 has the same structure and function as the first adjusting component 700, and will not be described again here.

[0068] In some embodiments, the second adjustment assembly 800 includes a third telescopic rod, a fourth telescopic rod, and a third fastener. The third telescopic rod is connected to the guide frame 100. The third and fourth telescopic rods are arranged vertically, with the fourth telescopic rod extending and retracting within the third telescopic rod. One end of the fourth telescopic rod is connected to the second guide wheel 620. The third telescopic rod has a plurality of fifth mounting holes spaced apart along the axial direction, and the fourth telescopic rod has a plurality of sixth mounting holes spaced apart along the axial direction. The fifth and sixth mounting holes are adapted to each other. The third fastener can pass through the fifth and sixth mounting holes to restrict the extension and retraction of the fourth telescopic rod relative to the third telescopic rod, thereby adjusting the vertical height of the second guide wheel 620.

[0069] Specifically, the third fastener can be a pin.

[0070] Specifically, the fifth and sixth mounting holes can be circular holes.

[0071] In another embodiment, the third and fourth telescopic rods can also be adjusted for telescopic movement via a threaded structure.

[0072] In some embodiments, the second adjusting assembly 800 includes a second slider, a second connector, and a fourth fastener. The second connector is connected to the end of the fourth telescopic rod away from the third telescopic rod. The second slider is capable of sliding relative to the connector in a horizontal direction. The second slider has a plurality of seventh mounting holes spaced apart in the axial direction. The second connector has an eighth mounting hole. The seventh mounting holes and the eighth mounting holes are adapted to each other. The fourth fastener passes through the seventh mounting holes and the eighth mounting holes to limit the sliding of the second slider relative to the second connector, thereby adjusting the horizontal distance of the second guide wheel 620.

[0073] Please refer to the following: Figure 2 In some embodiments, the guide frame 100 includes a first sidewall 910 and a second sidewall 920 disposed opposite to each other. The first sidewall 910 extends in a direction away from the second sidewall 920 and is provided with an extension 930. A second fixed pulley 300 is provided on the bottom side of the extension 930, and the extension 930 is located at the top of the first sidewall 910.

[0074] It should be noted that this structure causes the second fixed pulley 300 to be offset outward relative to the first side wall 910 by a certain distance. The counterweight 500 is suspended vertically downward under the traction of the traction rope 400. The extension 930 provides a horizontal clearance position for the counterweight 500 by extending outward, creating a gap between the counterweight 500 and the first side wall 910, preventing direct contact between the counterweight 500 and the first side wall 910 during lifting and lowering. The extension 930 provides dedicated clearance space for the vertically downward counterweight 500, preventing friction, collision, or jamming between the counterweight 500 and the first side wall 910, ensuring that the counterweight 500 can rise and fall freely and smoothly in the vertical direction.

[0075] Please refer to the following: Figure 5 In some embodiments, the guide frame 100 is provided with a first splicing part 940 and a second splicing part 950 on both sides along the axial direction, and the guide frame 100 is provided with multiple parts, and the first splicing part 940 and the second splicing part 950 of two adjacent guide frames 100 are spliced ​​together.

[0076] It should be noted that multiple guide frames 100 can be mechanically connected and engaged through the first splicing part 940 and the second splicing part 950 of adjacent guide frames 100. This allows multiple independent guide frames 100 to be sequentially spliced ​​in the axial direction, forming a single unit and thus creating a longer overall guide structure. This configuration allows for free combination to form guide devices 10 of different lengths, adapting to the usage requirements of long-sized folding screens 20. The splicing structure is easy to assemble and disassemble, and the connection is robust, improving the device's versatility and adaptability to different screen sizes and scenarios, while also facilitating transportation, storage, and rapid on-site assembly.

[0077] Specifically, both the first splicing part 940 and the second splicing part 950 are provided with pin holes, and the pins are inserted into the pin holes to achieve a fixed connection between the two adjacent guide frames 100. This structure uses the engagement of the pins and the pin holes to form radial limiting and axial fixing, so that the two adjacent guide frames 100 cannot be displaced relative to each other in the axial, horizontal and vertical directions, thereby achieving reliable splicing and fixing.

[0078] Please refer to the following: Figure 3 and Figure 4 Specifically, the guide device 10 further includes a first outer side plate 960 and a second outer side plate 970. The guide frame 100 has a first opening and a second opening at its two ends along the axial direction, respectively. The first outer side plate 960 is detachably connected to one end of the guide frame 100 and blocks the first opening. The second outer side plate 970 is detachably connected to the other end of the guide frame 100 and blocks the second opening.

[0079] It should be noted that the guide frame 100 has a first opening and a second opening at both ends along its axial direction, and the first outer side plate 960 and the second outer side plate 970 are respectively assembled at both ends of the guide frame 100. After the first outer side plate 960 and the second outer side plate 970 are assembled, they can cover and block the first opening and the second opening from the outside, forming a physical enclosure for the first opening and the second opening, and at the same time providing external shielding and protection for the internal space of the guide frame 100 and the built-in folding screen 20.

[0080] More specifically, the detachable connection between the guide frame 100 and the first outer side plate 960 and the second outer side plate 970 can be achieved through a pin and pin hole structure.

[0081] It should be noted that the guide frame 100, the first outer side plate 960, and the second outer side plate 970 are all equipped with matching pin holes, forming a universal connection structure through the insertion and engagement of the pins and pin holes. When multiple sets of guide frames 100 need to be axially spliced ​​together, the pins can be directly inserted into the aligned pin holes of the first splicing part 940 and the second splicing part 950 of adjacent guide frames 100 to complete the splicing and fixing, in which case it is not necessary to assemble the first outer side plate 960 and the second outer side plate 970. When the guide frame 100 is used alone without splicing, the first outer side plate 960 and the second outer side plate 970 are aligned and attached to both ends of the guide frame 100, and then pins of the same specification are inserted into the corresponding pin holes, so that the first outer side plate 960 and the second outer side plate 970 can be detachably fixed to the guide frame 100. The same pin structure is compatible with both assembly modes. This universal pin and pin hole structure can accommodate both the assembly of the guide frame 100 and the installation and fixing of the first outer side plate 960 and the second outer side plate 970, without the need for additional connectors, thus improving the device's adaptability and ease of use.

[0082] Please refer to the following: Figure 6 In some embodiments, the guide frame 100 is provided with a third splicing portion 980 and a fourth splicing portion 990 on both sides along the height direction. Two adjacent guide frames 100 along the vertical direction can be spliced ​​together by the third splicing portion 980 and the fourth splicing portion 990.

[0083] It should be noted that the guide frame 100 has a third splicing part 980 and a fourth splicing part 990 on both sides of its height. Two guide frames 100 arranged vertically can interlock by aligning the third splicing part 980 and the fourth splicing part 990, so that the upper and lower layers of guide frames 100 form a regular stacking structure in the vertical direction, realizing the layer-by-layer splicing combination of multiple sets of guide frames 100 in the vertical direction. The vertical stacking and splicing of guide frames 100 through the third splicing part 980 and the fourth splicing part 990 facilitates the centralized storage and logistics transportation of guide frames 100. Multiple guide frames 100 can be stacked vertically layer by layer, reducing the space occupied and facilitating the orderly storage and full-vehicle loading of batches.

[0084] Please refer to the following: Figures 3 to 6 In some embodiments, the bottom of the guide frame 100 is provided with a plurality of movable wheels 991.

[0085] The movable wheels 991 form a rolling support structure with the ground, converting the sliding friction between the guide frame 100 and the ground into rolling friction. Relying on multiple movable wheels 991 to evenly bear the overall weight of the guide frame 100 and its internal components, the guide frame 100 can be moved smoothly under the action of external force, realizing flexible movement and alignment, which facilitates the site transfer, position adjustment and on-site alignment and installation of the guide frame 100.

[0086] Specifically, the movable wheel 991 is equipped with a braking structure. When the guide frame 100 moves to the target installation position, the braking structure can be operated to brake and lock the movable wheel 991, restricting the movable wheel 991 from continuing to roll and slide, thus switching the movable wheel 991 from a movable state to a fixed stationary state.
