Description

Technical Field

[0001] The utility model relates to the technical field of intelligent display devices, and in particular to a fixed structure and a folding screen. Background Art

[0002] As a newly emerging innovative display device, the Light Emitting Diode (LED) foldable all-in-one device can flexibly meet the end-user's application needs in different spaces and venues due to its foldable and movable features.

[0003] The overall weight of a foldable LED all-in-one device places higher demands on its packaging and protection. Because the primary display module of an LED all-in-one device is a bare printed circuit board (PCB), its critical components are extremely fragile and attached to the PCB's outer surface. For better protection, the device is packaged separately from the display board. After the screen is folded, foam is used as a retaining force to prevent it from opening along its hinges during transport and potentially damaging the screen.

[0004] Although the above packaging method can well protect the screen during transportation, it cannot be well protected when moving between office areas or between upstairs and downstairs because there are usually no ready-made protective tools such as foam. The folding screen is easily damaged due to the relative movement of the two screens during movement. Utility Model Content

[0005] Based on this, it is necessary to provide a fixed structure and a folding screen to address the technical problem in the related art that the folding screen is easily damaged during daily movement.

[0006] A fixing structure is used in a folding screen, wherein the folding screen includes a fixed screen body and a movable screen body, wherein the movable screen body is hinged to the fixed screen body, and the fixing structure includes:

[0007] A fixing seat, the fixing seat being fixedly connected to the fixed screen body;

[0008] A movable plate, the movable plate is pivotally connected to the fixed seat, and a limiting protrusion is provided on the movable plate;

[0009] Wherein, when the fixed screen body and the movable screen body are folded together, the limiting protrusion is used to buckle into the limiting hole on the movable screen body to limit the movable screen body from rotating relative to the fixed screen body.

[0010] This embodiment provides a fixing structure, which is used in a folding screen. The fixing seat is fixedly connected to the fixed screen body, and the movable plate is pivotally connected to the fixing seat so that the movable plate can rotate relative to the fixed seat. A limiting protrusion is provided on the movable plate, so that when the fixed screen body and the movable screen body are folded, the limiting protrusion is buckled into the limiting hole on the movable screen body, so that the mutual limitation between the movable screen body and the fixed screen body is achieved through the mutual limitation between the limiting protrusion and the hole wall of the limiting hole. Such a setting is not only simple in structure, but also convenient for limiting the relative movement of the movable screen body and the fixed screen body, so that during daily movement, after the movable screen body and the fixed screen body are folded, the two are limited by the fixing structure, thereby preventing the mutual movement between the movable screen body and the fixed screen body during movement or transportation from causing damage to the two, thereby improving the safety performance of the folding screen during transportation. In one embodiment, a connecting lug is provided on the fixing seat;

[0011] Two ear plates are provided on the movable plate, and the two ear plates are spaced apart to form a mounting groove, and the connecting lug is arranged in the mounting groove;

[0012] The connecting lug is pivotally connected to the two ear plates.

[0013] A connecting lug is provided on the fixed seat, two ear plates are provided on the movable plate, and the two ear plates are spaced apart to form a mounting groove. The connecting lug is provided in the mounting groove to facilitate pivotal connection between the connecting lug and the ear plate.

[0014] In one embodiment, the connecting lug is provided with a connecting hole, the lug plate is provided with a mounting hole, and the fixing structure further comprises:

[0015] A pivot shaft is provided through the connecting hole and the mounting hole to realize the pivot connection between the connecting lug and the ear plate.

[0016] By providing a connecting hole on the connecting lug, providing a mounting hole on the ear plate, and passing a pivot shaft through the connecting hole and the mounting hole, the connecting lug is pivotally connected to the ear plate, thereby achieving a pivotal connection between the movable plate and the fixed seat. The connection via the pivot shaft has a simple structure and facilitates the pivotal connection of the two.

[0017] In one embodiment, one end of the pivot shaft is configured with a locally enlarged diameter limiting portion, and the fixing structure further comprises:

[0018] A locking piece is engaged with one end of the pivot shaft, and the limiting portion and the locking piece respectively abut against the opposite sides of the two ear plates to limit the pivot shaft from being separated from the ear plates and the connecting lug.

[0019] By constructing a locally enlarged diameter limiting portion at one end of the pivot shaft, by clamping a locking piece to one end of the pivot shaft, and abutting the locking piece against the side of the ear plate, one end of the pivot shaft is axially limited by the locking piece and the ear plate; the limiting portion of the pivot shaft is abutted against the side of the other ear plate to axially limit the other end of the pivot shaft, thereby preventing the pivot shaft from moving axially along the pivot shaft, preventing the pivot shaft from separating from the ear plate and the connecting lug, thereby ensuring the reliability of the pivotal connection between the movable plate and the fixed seat.

[0020] In one embodiment, the movable plate comprises:

[0021] The plate body, the ear plate is connected to one end of the plate body, and the two ear plates are bent relative to the plate body toward the same side in the thickness direction of the plate body.

[0022] The two ear plates are bent toward the same side relative to the plate body so that a concave space is formed in the plane where the plate body and the two ear plates are located, so as to avoid the structure on the fixed screen body, thereby preventing interference between the movable plate and the fixed screen body.

[0023] In one embodiment, the fixing structure further comprises:

[0024] The adsorption component is arranged on the movable plate. When the limiting protrusion is inserted into the limiting hole, the adsorption component is attracted to the fixed screen body or the fixing seat.

[0025] By arranging an adsorption piece on the movable plate, when the limiting protrusion on the movable plate is inserted into the limiting hole, the adsorption piece is attracted to the fixed screen body or the fixed seat to limit the movable plate, thereby preventing the limiting protrusion on the movable plate from being separated from the limiting hole on the movable screen body, thereby ensuring the reliability of the fixed structure in limiting the relative rotation of the movable screen body and the fixed screen body.

[0026] In one embodiment, the adsorbing member is a magnet, the fixing base is magnetic, and the adsorbing member and the fixing base are magnetically attracted to each other. Setting the adsorbing member as a magnet and setting the fixing base as a magnetic material so that the adsorbing member and the fixing base are magnetically attracted to each other, such a setting has a simple structure and reliable adsorption.

[0027] In one embodiment, the fixed screen body is configured with a decorative edge, the decorative edge including a first surface and a second surface arranged opposite to each other, the first surface being a surface close to the display module, the second surface being a surface away from the display module, and the decorative edge being configured with an avoidance hole extending from the first surface to the second surface;

[0028] The fixing seat is fixedly connected to the first surface. A suction protrusion is constructed on the fixing seat. The suction protrusion on the fixing seat is arranged in the avoidance hole. The adsorption component is attracted to the suction protrusion from one side of the second surface.

[0029] By connecting the fixing base to the decorative edge of the fixed screen body and forming a through-hole in the decorative edge, the suction protrusion on the fixing base can be positioned within the hole, and the suction member on the movable plate can enter the hole from the second side and engage with the suction protrusion on the fixing base. This arrangement eliminates any material requirements for the decorative edge while ensuring reliable suction between the suction member and the suction protrusion, thereby increasing flexibility in material selection for the decorative edge.

[0030] In one embodiment, the fixing structure further comprises:

[0031] A limiting block, the limiting block being connected to the back of the fixed screen body and the limiting block being connected to the decorative edge;

[0032] The movable plate is flipped to a preset position in a direction away from the movable screen body, the movable plate is attracted to the limit block, and the movable plate is stored on the back side of the fixed screen body.

[0033] By arranging a limit block on the fixed screen body, when there is no need to limit the movable screen body by interlocking the limit protrusion on the movable plate with the limit hole on the movable screen body, the limit block can be attracted to the movable plate to achieve the limitation of the movable plate, thereby facilitating the fixing of the movable plate to prevent the movable plate from moving, so that the movable plate can be stored on the back of the fixed screen body, thereby ensuring the safety performance of the folding screen while ensuring the aesthetics of the folding screen.

[0034] A folding screen comprises the fixing structure described above.

[0035] By using the above-mentioned fixed structure in the folding screen, the movement of the movable screen body relative to the fixed screen body is limited by the fixed structure, so that during daily movement, after the movable screen body and the fixed screen body are folded, the two are limited by the fixed structure, thereby preventing the mutual movement between the movable screen body and the fixed screen body during movement or transportation from causing damage to the two, thereby improving the safety performance of the folding screen during transportation.

[0036] Beneficial effects of the utility model:

[0037] The utility model provides a fixing structure for use in a folding screen. The fixing seat is fixedly connected to the fixed screen body, and the movable plate is pivotally connected to the fixing seat so that the movable plate can rotate relative to the fixing seat. A limiting protrusion is provided on the movable plate, so that when the fixed screen body and the movable screen body are folded together, the limiting protrusion is buckled into the limiting hole on the movable screen body, and the mutual limiting between the limiting protrusion and the hole wall of the limiting hole is achieved. Such a setting is not only simple in structure, but also convenient for limiting the relative movement of the movable screen body and the fixed screen body. Therefore, during daily movement, after the movable screen body and the fixed screen body are folded, the fixing structure limits the two, thereby preventing the movable screen body and the fixed screen body from being damaged by collision during movement or transportation, thereby improving the safety performance of the folding screen during transportation. In addition, when the limiting protrusions on the movable plate are engaged with the limiting holes on the movable screen body, the movable screen body can maintain a certain angle, making it convenient for the hand to easily grasp the screen body for operation.

[0052] As a newly emerging innovative display device, the Light Emitting Diode (LED) foldable all-in-one device can flexibly meet the end-user's application needs in different spaces and venues due to its foldable and movable features.

[0053] The overall weight of a foldable LED all-in-one device places higher demands on its packaging and protection. Because the primary display module of an LED all-in-one device is a bare printed circuit board (PCB), its critical components are extremely fragile and attached to the PCB's outer surface. For better protection, the device is packaged separately from the display board. After the screen is folded, foam is used as a retaining force to prevent it from opening along its hinges during transport and potentially damaging the screen.

[0054] Although the above packaging method can provide good protection for the screen during transportation, it cannot be well protected when moving between office areas or upstairs and downstairs because there are usually no ready-made protective tools such as foam. The folding screen is easily damaged due to the relative rotation of the two screens during movement.

[0055] Based on this, an embodiment of the present utility model provides a fixing structure for limiting the rotation of the movable screen body of the folding screen relative to the fixed screen body, by fixedly connecting the fixing seat with the fixed screen body, pivotally connecting the movable plate with the fixed seat, and snapping the limiting protrusion on the movable plate into the limiting hole on the movable screen body to limit the movement of the movable screen body relative to the fixed screen body, thereby preventing the mutual rotation between the movable screen body and the fixed screen body during the movement or transportation of the folding screen from causing collision and damage to the two, thereby improving the safety performance of the folding screen during transportation.

[0056] See Figures 1 to 6 An embodiment of the present invention provides a fixing structure 110 for use in a folding screen 100. The folding screen 100 includes a fixed screen body 120 and a movable screen body 130. The movable screen body 130 is hinged to the fixed screen body 120. The fixing structure 110 includes a fixing seat 111 and a movable plate 112. The fixing seat 111 is fixedly connected to the fixed screen body 120; the movable plate 112 is pivotally connected to the fixing seat 111, and a limiting protrusion 1121a is provided on the movable plate 112; wherein, when the fixed screen body 120 and the movable screen body 130 are folded, the limiting protrusion 1121a is used to buckle into the limiting hole 1311 on the movable screen body 130 to limit the rotation of the movable screen body 130 relative to the fixed screen body 120.

[0057] This embodiment provides a fixing structure 110, which is used in a folding screen 100. The fixing base 111 is fixedly connected to the fixed screen body 120, and the movable plate 112 is pivotally connected to the fixing base 111, so that the movable plate 112 can rotate relative to the fixing base 111. By providing a limiting protrusion 1121a on the movable plate 112, when the fixed screen body 120 and the movable screen body 130 are folded together, the limiting protrusion 1121a is buckled into the limiting hole 1311 on the movable screen body 130, and the mutual limiting between the limiting protrusion 1121a and the hole wall of the limiting hole 1311 is achieved, thereby achieving mutual limiting between the movable screen body 130 and the fixed screen body 120. Such a setting not only has a simple structure, but also facilitates limiting the relative rotation of the movable screen body 130 and the fixed screen body 120, so that during daily movement, after the movable screen body 130 and the fixed screen body 120 are folded, the two are limited by the fixed structure 110, thereby preventing the mutual rotation between the movable screen body 130 and the fixed screen body 120 during movement or transportation from causing damage to the two, thereby improving the safety performance of the folding screen 100 during transportation. It can be understood that when the movable screen body 130 and the fixed screen body 120 are folded, there is a certain angle between the movable screen body 130 and the fixed screen body 120. When the limiting protrusion 1121a on the movable plate 112 is engaged with the limiting hole 1311 on the movable screen body 130, the movable screen body 130 can maintain this angle, making it convenient for the hand to easily grasp the screen body for operation.

[0058] It is understood that in this embodiment, the movable screen body 130 is hinged to the fixed screen body 120 in the folding screen 100, so that the movable screen body 130 can rotate relative to the fixed screen body 120 around the hinge axis, thereby realizing the folding or unfolding function of the movable screen body 130. There is no limit to the number of movable screen bodies 130, such as Figure 1 and Figure 2 As shown, a movable screen body 130 can be hinged at both ends of a fixed screen body 120 ; of course, a movable screen body 130 can also be hinged at one end of the fixed screen body 120 .

[0059] There is no restriction on the connection position of the fixing base 111 on the fixed screen body 120. In some embodiments, both the fixed screen body 120 and the movable screen body 130 are provided with decorative edges, and the fixing base 111 is fixedly connected to the fixed screen body 120. In this arrangement, it is only necessary to connect the fixing base 111 to the decorative edge, without damaging other structures of the fixed screen body 120. It should be noted that a fixing structure 110 is provided at the top and bottom of the folding screen 100 to improve the reliability of the connection and limit of the fixed screen body 120 and the movable screen body 130.

[0060] Specifically, a fixing seat 111 is connected to the decorative edge at the top of the fixed screen 120, and a limiting hole 1311 is provided on the decorative edge at the top of the movable screen 130. Correspondingly, a fixing seat 111 is connected to the decorative edge at the bottom of the fixed screen 120, and a limiting hole 1311 is provided on the decorative edge at the bottom of the movable screen 130. When the movable screen 130 is rotated to fold with the fixed screen 120, the limiting protrusions 1121a on the corresponding movable panels 112 at the top and bottom can be snapped into the limiting holes 1311 corresponding to the decorative edge 131 of the movable screen to limit the movable screen 130.

[0061] In this embodiment, the limiting protrusion 1121a is a cylindrical protrusion, and the limiting hole 1311 is a circular hole.

[0062] like Figure 5 and Figure 6 As shown, in one embodiment, a connecting lug 1111 is provided on the fixing seat 111; two ear plates 1122 are provided on the movable plate 112, and the two ear plates 1122 are spaced apart to form a mounting groove, and the connecting lug 1111 is provided in the mounting groove; the connecting lug 1111 is pivotally connected to the two ear plates 1122.

[0063] By setting a connecting lug 1111 on the fixed seat 111, setting two ear plates 1122 on the movable plate 112, and arranging the two ear plates 1122 at intervals to form a mounting groove, and by arranging the connecting lug 1111 in the mounting groove, the connecting lug 1111 and the ear plates 1122 are pivotally connected.

[0064] like Figure 5 and Figure 6 As shown, specifically, the fixing seat 111 is a plate-like structure, and a long strip-shaped lug is provided at one end of the plate body of the fixing seat 111, and the end of the lug facing away from the plate body is constructed as an arc surface. Looking along the arrangement direction of the two lug plates 1122, that is, looking in the thickness direction of the lug plates 1122, the lug plates 1122 are flat structures; looking along the length direction of the lug plates 1122, the end at which the lug plates 1122 are connected to the connecting lug 1111 of the fixing seat 111 is constructed as an arc shape. This arrangement not only prevents the movable plate 112 and the fixing seat 111 from colliding with the folding screen 100 during assembly, but also facilitates the relative rotation of the two. The two lug plates 1122 are parallel to each other, and the distance between the two lug plates 1122 is slightly larger than the width of the connecting lug 1111. Such a configuration not only ensures the rotation of the movable plate 112 relative to the fixed seat 111, but also, when the two rotate relative to each other, the connecting lug 1111 can guide the lug plate 1122, thereby preventing the movable plate 112 from deflecting, thereby ensuring that the limiting lug on the movable plate 112 can be quickly buckled into the limiting hole 1311 on the movable screen body 130.

[0065] like Figure 5 and Figure 6 As shown, in one embodiment, a connecting lug 1111 is provided with a connecting hole 1111a, and a mounting hole 1122a is provided on the ear plate 1122. The fixing structure 110 further includes a pivot shaft 113, which is passed through the connecting hole 1111a and the mounting hole 1122a to achieve a pivotal connection between the connecting lug 1111 and the ear plate 1122. Furthermore, one end of the pivot shaft 113 is configured with a locally enlarged limiting portion. The fixing structure 110 further includes a locking member 1142, which is engaged with one end of the pivot shaft 113. The limiting portion 1131 and the locking member 1142 respectively abut against opposite sides of the two ear plates 1122 to prevent the pivot shaft 113 from being separated from the ear plate 1122 and the connecting lug 1111.

[0066] By providing a connecting hole 1111a on the connecting lug 1111, providing a mounting hole 1122a on the ear plate 1122, and passing the pivot shaft 113 through the connecting hole 1111a and the mounting hole 1122a, the connecting lug 1111 and the ear plate 1122 are pivotally connected, thereby achieving a pivotal connection between the movable plate 112 and the fixed base 111. The connection via the pivot shaft 113 has a simple structure and facilitates the pivotal connection between the two. By constructing a locally enlarged limiting portion 1131 at one end of the pivot shaft 113, by clamping the locking member 1142 to one end of the pivot shaft 113, and by abutting the locking member 1142 against the side of the ear plate 1122, one end of the pivot shaft 113 is axially limited by the locking member 1142 and the ear plate 1122; the limiting portion 1131 of the pivot shaft 113 is abutted against the side of the other ear plate 1122 to axially limit the other end of the pivot shaft 113, thereby preventing the pivot shaft 113 from moving axially along the pivot shaft 113, and preventing the pivot shaft 113 from separating from the ear plate 1122 and the connecting lug 1111, thereby ensuring the reliability of the pivotal connection between the movable plate 112 and the fixed seat 111.

[0067] In this embodiment, if Figure 6As shown, a limiting portion 1131 is provided at one end of the pivot shaft 113, and the axis of the pivot shaft 113 serves as the optical axis. When the pivot shaft 113 is inserted into the connecting hole 1111a and the mounting hole 1122a, the limiting portion 1131 is used to limit the pivot shaft 113, thereby restricting the pivot shaft 113 from axial movement and disengaging the connecting lug 1111 and the lug plate 1122. A limiting groove 1132 is provided at the end of the pivot shaft 113 facing away from the limiting portion 1131. The retaining member 1142 is a flat structure with a hexagonal groove 1141 with one end open. The hexagonal groove 1141 extends through the retaining member 1142 along its thickness. This arrangement facilitates deformation of the opening of the hexagram slot 1141 when the shaft section corresponding to the limiting groove 1132 in the pivot shaft 113 is clamped into the hexagram slot 1141, thereby facilitating the insertion of the pivot shaft 113 into the hexagram slot 1141. When the pivot shaft 113 no longer exerts force on the opening of the hexagram slot 1141 of the retaining member 1142, the opening contracts under the elastic restoring force, thereby preventing the pivot shaft 113 from separating from the hexagram slot 1141. In this embodiment, by providing the limiting groove 1132 on the pivot shaft 113, the retaining member 1142 is limited by the groove wall of the limiting groove 1132, thereby preventing the retaining member 1142 from moving axially along the pivot shaft 113.

[0068] It is understandable that when the fixing seat 111 is fixed to the top or bottom of the fixed screen body 120 , the axis of the pivot shaft 113 is perpendicular to the rotation axis between the fixed screen body 120 and the movable screen body 130 .

[0069] like Figure 5 and Figure 6 As shown, in one embodiment, the movable panel 112 includes a panel body 1121, and a lug 1122 connected to one end of the panel body 1121. The two lugs 1122 are bent toward the same side in the thickness direction of the panel body 1121 relative to the panel body. The two lugs are bent toward the same side relative to the panel body so that a concave space is formed in the plane where the panel body 1121 and the two lugs 1122 lie. This facilitates avoiding structures on the fixed screen body 120, thereby preventing interference between the movable panel 112 and the fixed screen body 120.

[0070] In this embodiment, the angle between the plane where the two ear plates 1122 are located and the plate body 1121 is an obtuse angle, for example, it can be 135 degrees or 120 degrees, and the specific adaptive adjustment is made depending on the structure of the decorative edge.

[0071] like Figure 5 and Figure 6As shown, in one embodiment, the fixed structure 110 further includes an adsorption member 1121b, which is provided on the movable plate 112. When the limiting protrusion 1121a is inserted into the limiting hole 1311, the adsorption member 1121b is attracted to the fixed screen body 120 or the fixing seat 111.

[0072] By providing an adsorption member 1121b on the movable plate 112, when the limiting protrusion 1121a on the movable plate 112 is inserted into the limiting hole 1311, the adsorption member 1121b is attracted to the fixed screen body 120 or the fixed seat 111 to limit the movable plate 112, thereby preventing the limiting protrusion 1121a on the movable plate 112 from being separated from the limiting hole 1311 on the movable screen body 130, thereby ensuring the reliability of the fixed structure 110 in limiting the relative movement of the movable screen body 130 and the fixed screen body 120.

[0073] There is no limitation on the specific structure of the adsorption member 1121b. The adsorption member 1121b may be a magnetic structure or a vacuum suction cup structure.

[0074] It is understood that by attracting the adsorption member 1121b on the movable plate 112 to the fixed screen body 120 or the fixing seat 111, when the fixing structure 110 is set at the bottom of the folding screen 100, the adsorption of the adsorption member 1121b to the fixed screen body 120 or the fixing seat 111 can prevent the movable plate 112 from falling downward due to its own gravity, so that the limiting protrusion 1121a is separated from the limiting hole 1311. Such a configuration is conducive to improving the reliability of limiting the movable screen body 130.

[0075] In one embodiment, the adsorption member 1121b is a magnet, the fixing base 111 is magnetic, and the adsorption member 1121b is magnetically attracted to the fixing base 111. Setting the adsorption member 1121b as a magnet and setting the fixing base 111 as a magnetic material allows the adsorption member 1121b and the fixing base 111 to be magnetically attracted to each other. This configuration has a simple structure and reliable adsorption.

[0076] In this embodiment, the movable plate 112 and the fixed base 111 are both constructed of magnetic carbon steel, and the adsorbent 1121b is constructed of a strong magnetic material, Ru-Fe-B. The adsorbent 1121b is configured as a cylindrical structure and fixedly attached to the plate body 1121. The adsorbent 1121b can be bonded to the plate body 1121, or it can be installed in a fixing hole defined in the plate body 1121 through an interference fit.

[0077] like Figure 5 and Figure 6As shown, in one embodiment, the fixed screen body 120 is constructed with a decorative edge, and the decorative edge includes a first surface and a second surface arranged opposite to each other, the first surface is the surface close to the display module, and the second surface is the surface away from the display module, and the decorative edge is constructed with an avoidance hole running from the first surface to the second surface; the fixed seat 111 is fixedly connected to the first surface, and a suction protrusion 1112 is constructed on the fixed seat 111, and the suction protrusion 1112 on the fixed seat 111 is arranged in the avoidance hole, and the adsorption member 1121b is attracted to the suction protrusion 1112 from the side of the second surface.

[0078] By connecting the fixing base 111 to the decorative edge on the fixed screen body 120 and forming a through-hole in the decorative edge, the suction protrusion 1112 on the fixing base 111 can be positioned within the hole, and the suction member 1121b on the movable plate 112 can enter the hole from the second surface and be suctioned to the suction protrusion 1112 on the fixing base 111. This arrangement does not require a specific material for the decorative edge while ensuring reliable suction between the suction member 1121b and the suction protrusion, thereby increasing flexibility in selecting the material for the decorative edge.

[0079] Specifically, the fixing base 111 is fixed to the first surface of the fixed screen body 120 by bolts, and the suction protrusion 1112 on the fixing base 111 is inserted from the first surface into the avoidance hole on the fixed screen body 120. When the movable plate 112 rotates until the limiting protrusion 1121a is inserted into the limiting hole 1311 on the movable screen body 130, the suction member 1121b can just be inserted into the avoidance hole to be sucked together with the suction protrusion 1112.

[0080] like Figure 3 、 Figure 4 and Figure 6 As shown, in one embodiment, the fixed structure 110 further includes a limit block 115, which is connected to the back of the fixed screen body 120, and the limit block 115 is connected to the decorative edge; wherein, the movable panel 112 flips to a preset position in a direction away from the movable screen body 130, and the movable panel 112 is attracted to the limit block 115, and the movable panel 112 is stored in the back of the fixed screen body 120.

[0081] By arranging a limit block 115 on the fixed screen body 120, when there is no need to engage the limit protrusion 1121a on the movable plate 112 with the limit hole 1311 on the movable screen body 130 to limit the movable screen body 130, the limit block 115 can be attracted to the movable plate 112 to achieve the limitation of the movable plate 112, thereby facilitating the fixing of the movable plate 112 to prevent the movable plate 112 from moving, so that the movable plate 112 can be stored on the back of the fixed screen body 120, thereby ensuring the safety performance of the folding screen 100 while ensuring the aesthetics of the folding screen 100.

[0082] like Figure 3 and Figure 4 As shown, in this embodiment, the limit block 115 is fixedly connected to the side surface of the back of the fixed screen body 120 by bolts, and the limit block 115 is parallel to the large plane of the fixed screen body 120. It is understandable that the material of the limit block 115 is also selected to be magnetic carbon steel, so that after the movable plate 112 is flipped, the movable plate 112 can be attracted to the limit plate.

[0083] It should be noted that the back side of the fixed screen body 120 mentioned above refers to the side of the fixed screen body 120 away from the display surface, and the display surface is the surface of the fixed screen that can display images.

[0084] like Figures 1 to 4 As shown, a folding screen 100 includes the above-mentioned fixing structure 110. By using the above-mentioned fixing structure 110 in the folding screen 100, the movement of the movable screen body 130 relative to the fixed screen body 120 is limited by the fixing structure 110. Therefore, during daily movement, after the movable screen body 130 and the fixed screen body 120 are folded, the fixing structure 110 limits the two, thereby preventing the movable screen body 130 and the fixed screen body 120 from rotating relative to each other during movement or transportation, thereby improving the safety performance of the folding screen 100 during transportation.

[0085] Reference Figures 1 to 6 It is understood that the method of using the fixing structure 110 provided by the present invention is as follows:

[0086] When the fixed screen 120 and the movable screen 130 are folded together, the movable plate 112 of the fixed structure 110 is folded up, and the cylindrical limiting protrusion 1121a on the movable plate 112 is inserted into the limiting hole 1311 of the decorative edge 131 of the corresponding movable screen. The magnet serving as the adsorption member 1121b is attracted to the suction protrusion 1112 on the fixed seat 111, thereby firmly adsorbing the movable plate 112 and thus fixing the movable screen 130, preventing the movable screen 130 from rotating and being damaged, or striking and extending to injure people during the movement of the folding screen 100. When the limiting protrusion 1121a on the movable plate 112 is engaged with the limiting hole 1311 on the movable screen 130, the movable screen 130 can maintain a certain angle, making it easy for the hand to grasp the screen for operation. When the movable plate 112 is opened, the limiting block 115 can attract the movable plate 112 through the magnet on the movable plate 112 to prevent the movable plate 112 from falling.

[0087] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
