Description

Technical Field

[0001] This invention relates to the field of office and teaching equipment technology, and in particular to a combined guide rail writing board and its installation method. Background Technology

[0002] Sliding whiteboards are a common teaching and presentation tool in classrooms, meeting rooms, or training venues. These whiteboards typically consist of an outer frame, a fixed panel, and a movable panel. The movable panel slides in front of the fixed panel, allowing for segmented use of the writing area or concealing multimedia devices.

[0003] A traditional sliding writing tablet consists of an outer frame, a fixed plate, and a movable plate. The outer frame, made of aluminum profile, runs along the four edges of the writing tablet, providing support and guidance. The fixed plate is fixedly installed inside the outer frame, forming the main body of the writing tablet. The aluminum profile has shaped guide rails, typically grooves or slides. The movable plate slides within these guide rails, allowing it to move relative to the fixed plate.

[0004] Because writing boards are typically quite long—for example, the aluminum frame in some large classrooms can reach 4 meters in length—large vehicles are required for transportation, leading to higher costs, especially in rural areas. Furthermore, long aluminum profiles are difficult to move through conventional elevators and can easily get stuck at stair bends, causing transport difficulties. While designing a modular aluminum profile structure could shorten individual sections, it would reduce the overall structural strength of the writing board frame, affecting its stability. Additionally, exposed seams at the joints of the modular frame would compromise the overall aesthetics and appearance of the writing board. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a combined guide rail writing board to solve the problems of inconvenient transportation, difficult installation and large sliding noise caused by the excessively long outer frame of the sliding writing board in the existing technology.

The inner end of the guide rail is installed on the side plate of the connector, and the outer end is installed on the side plate of the fixing frame.

[0012] Optionally, locking nuts are installed at both ends of the guide rail, and a butterfly spring is provided between the locking nuts and the side plate of the connector or the side plate of the fixing frame.

[0013] Optionally, a movable frame is provided on the top of the movable plate, and the movable plate and the movable frame form a movable component. The movable frame includes a connecting plate and a support plate. The connecting plate is installed on the top of the movable plate, and the support plate is installed on the connecting plate through an elongated groove. The support plate is equipped with rollers, and the rollers roll on the guide rail.

[0014] Optionally, the support plate includes an upper horizontal plate, a vertical plate, and a lower horizontal plate. The vertical plate is located between the upper and lower horizontal plates, forming a C-shaped structure. The upper horizontal plate is mounted on the connecting plate, the roller is mounted on the inner side of the vertical plate, and the guide rail is located between the roller and the lower horizontal plate.

[0015] Optionally, the guide rail includes a top guide rail and a bottom guide rail, the roller rolls on the top guide rail, and a limiting member is installed at the bottom of the movable plate, the limiting member sliding along the bottom guide rail.

[0016] Optionally, the limiting member is L-shaped in general, including a horizontal mounting part and a vertical limiting part. The mounting part is fixed to the bottom of the movable plate, and the limiting part has an opening groove or through hole, with the bottom guide rail passing through the opening groove or through hole.

[0017] Optionally, the writing board further includes a linkage mechanism, which has two symmetrically arranged sets. The linkage mechanism includes a pull wire and a rotating wheel. The rotating wheel is fixedly installed at the end of the fixed plate.

[0021] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages: The writing board structure of this invention changes the traditional frame guide rail form, adopting a split, combinable guide rail formed by guide rails and connectors. The two ends of the guide rail are fixed to the connectors, and the movable board can slide along the split, combinable guide rail. In the prior art, the guide rail is part of the aluminum profile outer frame, with the frame itself serving as both a support frame and a guiding structure. This application, by splitting the guide rail into a combination of guide rails and connectors, eliminates the need for an integrated long frame, saving the traditional frame structure of the writing board. This greatly simplifies the structure, saves materials, reduces costs, and makes the overall design more concise and aesthetically pleasing. The guide rail can be made of slender materials that are easy to cut and coil, such as round bars or steel wire ropes, allowing the various components of the writing board to be packaged separately during transportation. This significantly shortens the size of individual packages, making it suitable for transportation in small vehicles and handling environments such as elevators and stairs, solving the logistics, handling, and installation problems caused by excessively long frame borders. Compared to the separate frame splicing method, this structure changes the installation method while ensuring overall strength. Furthermore, the separate, combinable guide rails are all located on the back of the fixed and movable plates, without affecting the appearance and improving the overall visual effect of the writing board. Moreover, since there is no need for a bulky aluminum profile outer frame, the noise amplification effect of the cavity structure is avoided, reducing noise and improving the user experience.

[0022] Advantages of additional aspects of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0025] Example 1 This embodiment proposes a writing board, the board body of which can be various types of boards such as blackboard, whiteboard, magnetic board or light energy board.

[0026] like Figure 1 , Figure 2 , Figure 3As shown, the writing board includes a fixed plate 11 and a movable plate 21. The movable plate 21 is combined with the fixed plate 11 via a sliding mechanism 3 to form the writing board. Depending on the specific site conditions, the fixed plate 11 and the movable plate 21 can form various combinations. For example, a common configuration is two fixed plates 11 and two movable plates 21 at each end. It is understood that in other embodiments, the fixed plate 11 and the movable plate 21 can be combined in other ways. The number of fixed plates 11 and the number of movable plates 21 can be the same or different; for example, one or more fixed plates 11 can be combined with one or more movable plates 21. Figure 4 , Figure 9 As shown, the sliding mechanism 3 includes at least two guide rails 32 and at least one connector 31. The guide rails 32 are connected by the connector 31, and the guide rails 32 and the connector 31 form a split-type combinable guide rail. The two ends of the split-type combinable guide rail and the connector 31 are fixedly installed, and the split-type combinable guide rail is located behind the fixed plate 11 and the movable plate 21. The movable plate 21 can slide along the split-type combinable guide rail.

[0027] The number of connectors 31 can be selected according to the number of guide rails 32 and installation requirements. The number of connectors 31 is usually one less than the number of guide rails 32. For example, when there are three guide rails 32, two connectors 31 can be used to connect adjacent guide rails 32 end to end; when there are four guide rails 32, three connectors 31 can be used to connect them, and so on.

[0028] This writing board changes the structural design of the integral aluminum profile outer frame in the existing technology. The movable plate 21 is directly assembled to the fixed plate 11 through the sliding mechanism 3. The sliding mechanism 3 is composed of guide rail 32 and connector 31. The guide rail 32 is connected to each other through the connector 31. The guide rail 32 and the connector 31 together form an integral guide rail that allows the movable plate 21 to slide.

[0029] Specifically, the guide rail 32 can be made of rigid rods such as round bars or flexible structural components such as steel wire ropes, as long as it can provide a sliding path for the moving plate 21 and be tightened by the connecting member 31 to maintain straightness. The cross-section of the guide rail 32 can be selected according to actual assembly requirements, such as circular, rectangular, trapezoidal, triangular, dovetail, etc., or it can be designed into other irregular shapes according to sliding requirements. The sliding mechanism 3 can also be directly replaced by a maintenance-free linear guide rail.

[0030] Since the movable plate 21 consists of multiple independent plates, the guide rails used for sliding only need to meet the travel distance of each plate. Based on this, the overall guide rail of the writing board can be connected by connectors 31 to connect the separate guide rails 32, with each guide rail 32 corresponding to the travel distance of one movable plate 21. This eliminates the need for long aluminum profile structural components; the overall guide rail can be made into a split structure. The split components are smaller, eliminating the need for large transport vehicles; small vehicles can handle the transportation. Furthermore, the split components can fit into conventional elevators, and there will be no jamming or turning issues when manually moving them through stairs, significantly reducing the difficulty of transportation and handling, and correspondingly reducing transportation and installation costs.

[0031] The guide rail 32 is connected to the connector 31 to form an integral guide rail. The connector 31 can tighten the guide rail 32, so that the guide rail 32 maintains good straightness, improves the smoothness of sliding, and avoids the problem of sliding jamming.

[0032] By eliminating the outer frame of the aluminum profile and removing the cavity structure of the aluminum profile, the sound will not be amplified in the cavity when the moving plate 21 slides, thus structurally solving the technical problem of high sliding noise.

[0033] The mating structure of guide rail 32 and connector 31 replaces the traditional aluminum profile guide rail structure, eliminating the need to form guide rails on aluminum profiles and simplifying the processing technology of parts. At the same time, guide rail 32 is made of materials such as round bars or steel wire ropes, which significantly reduces material costs compared to the outer frame of aluminum profiles.

[0034] The fixed plate 11 provides a fixed base for the guide rail 32. The guide rail 32 and the connecting piece 31 form an integral guide rail, which provides a sliding path for the moving plate 21. The components cooperate with each other to form a complete sliding system, which ensures the overall stability of the sliding structure and ensures that the sliding process of the moving plate 21 remains stable.

[0035] like Figure 5 As shown, the writing board includes left and right fixing plates 11, with a set gap between the two fixing plates 11. The gap is used to arrange a multimedia display screen. When arranging the multimedia display screen, the split-type combinable guide rail is also located on the rear side of the multimedia display screen. The top and bottom sides of the two fixing plates 11 are connected by a connecting strip 12 in the middle to form an integral fixing component 1. The two ends of the connecting strip 12 are detachably connected to the fixing plates 11 on both sides.

[0036] The fixing plate 11 is designed as a split structure with left and right sides, and with the detachable connecting strip 12, the fixing component 1 can be disassembled and assembled separately, facilitating transportation and on-site installation. At the same time, the split fixing plate 11 structure allows for flexible adjustment of the gap between the two fixing plates 11 according to the actual size of the multimedia display screen, improving the adaptability of the writing tablet. The writing tablet and multimedia display screen combine writing and multimedia display functions, meeting diverse usage needs in office and teaching settings.

[0037] The two fixing plates 11 are connected by connecting strips 12 to form an integral fixing component 1, so that the separate fixing plates 11 form a unified force-bearing structure, which can provide a stable installation foundation for the sliding mechanism 3 and the moving plate 21, and avoid the situation of unstable installation foundation due to the separate fixing plates 11.

[0038] The connecting strip 12 can be made of aluminum profile. Aluminum profile is lightweight and will not add too much weight to the fixing component 1. In addition, aluminum profile has good corrosion resistance and structural strength, which can ensure the connection effect for a long time and keep the two fixing plates 11 in a stable relative position.

[0039] In addition to aluminum profiles, the connecting strip 12 can also be made of stainless steel, rigid engineering plastics, or other structural components, as long as the structural strength is guaranteed and the detachable connection to the fixing plates 11 on both sides is achieved. The detachable connection between the connecting strip 12 and the fixing plates 11 can be achieved through different methods such as bolt connection, snap-fit ​​connection, or pin connection, as long as a reliable connection is achieved and disassembly and assembly are convenient.

[0040] like Figure 6 As shown, the fixing component 1 also includes a fixing frame 15, which is installed on the back side of the fixing plate 11, and the fixing plate 11 is installed on the wall base by the fixing frame 15.

[0041] The mounting bracket 15 provides stable support for the mounting plate 11, allowing it to be firmly fixed to the wall base. Since the bracket 15 is installed on the back of the mounting plate 11, it does not occupy the usable space on the front of the writing board or affect its appearance. Furthermore, the bracket 15 provides a good foundation for the installation of the sliding mechanism 3.

[0042] like Figure 7 As shown, the fixing frame 15 includes a first adjusting frame 151 and a first fixing member 152. The first fixing member 152 is fixedly installed on the wall base. The first adjusting frame 151 has an elongated groove, and the first adjusting frame 151 is installed on the threaded hole of the first fixing member 152 through the elongated groove.

[0043] The first fixing member 152 is connected to the wall base, for example, by using expansion screws or other methods, as long as it can be firmly fixed to the wall base and provide a connection base for the first adjusting frame 151. The first adjusting frame 151 is connected to the first fixing member 152 through an elongated groove. Utilizing the structural characteristics of the elongated groove, the position of the first adjusting frame 151 relative to the first fixing member 152 can be adjusted during installation, thereby adjusting the position of the fixing plate 11 relative to the wall base and the gap between the fixing plate 11 and the wall base. On the one hand, this can reserve sufficient installation space for the sliding mechanism 3 and the subsequent linkage mechanism 4, avoiding component assembly interference problems caused by insufficient installation space. On the other hand, it can adapt to uneven wall bases, and by adjusting and compensating for the flatness deviation of the wall base, it can keep the fixing plate 11 in a flat installation state, thereby keeping the overall surface of the writing board flat.

[0044] The elongated groove design makes position adjustment easier, allowing for fine-tuning without disassembling parts, thus improving installation efficiency. After adjustment, it can be reliably fixed with fasteners to ensure that the adjusted position will not shift.

[0045] In other embodiments, the elongated groove can also be formed on the first fixing member 152, and the first adjusting frame 151 can be provided with a matching connecting hole, which can also realize the function of position adjustment, as long as the position adjustment of the first adjusting frame 151 relative to the first fixing member 152 can be realized through the groove and hole.

[0046] Furthermore, such as Figure 5 As shown, the outer side of the fixing plate 11 is provided with an edge sealing structure, which includes an inner sealing plate 13 and an outer sealing plate 14. The inner sealing plate 13 is fixed to the side of the fixing frame 15, and the outer sealing plate 14 is installed on the outer side of the inner sealing plate 13 through an elongated groove.

[0047] The inner cover plate 13 is fixed to the side of the fixing frame 15, and the outer cover plate 14 is installed on the outside of the inner cover plate 13. It can fully cover the outer edge of the writing board and hide the internal structure such as the sliding mechanism 3 of the fixing frame 15 on the inside of the writing board, so as to avoid seeing the internal parts and connecting structures from the outside, making the overall appearance of the writing board cleaner and more beautiful.

[0048] The outer sealing plate 14 is installed on the outside of the inner sealing plate 13 through an elongated groove. By utilizing the structural characteristics of the elongated groove, the position of the outer sealing plate 14 relative to the inner sealing plate 13 can be adjusted, thereby allowing the edge sealing structure to adapt to the gap between the fixing plate 11 and the wall, thus improving the edge sealing effect.

[0049] Specifically, the inner sealing plate 13 and the outer sealing plate 14 can be made of different materials such as metal sheets, plastic sheets, and wood sheets, as long as they can achieve the functions of covering and protection and have a certain structural strength. The elongated groove adjustment structure between the outer sealing plate 14 and the inner sealing plate 13 can be made on either the inner sealing plate 13 or the outer sealing plate 14, as long as the position of the outer sealing plate 14 relative to the inner sealing plate 13 can be adjusted.

[0050] like Figure 8 As shown, the connector 31 includes a second adjusting frame 311 and a second fixing member 312. The second fixing member 312 is fixedly installed on the wall base, and the second adjusting frame 311 is installed on the second fixing member 312 through an elongated groove. The inner end of the guide rail 32 is installed on the side plate of the connector 31, and the outer end is installed on the side plate of the fixing frame 15. The guide rail 32 is tightened by the connector 31 and the fixing frame 15.

[0051] The second fixing member 312 is connected to the wall base, providing a stable installation base for the connector 31. The second adjusting frame 311 is connected to the second fixing member 312 through the elongated groove, which can adjust the position of the second adjusting frame 311 relative to the second fixing member 312, thereby adjusting the relative position between the two members, ensuring the straightness of the guide rail 32, and thus ensuring the smoothness of the sliding.

[0052] The inner end of the guide rail 32 is installed on the side plate of the connector 31, and the outer end is installed on the side plate of the fixing frame 15, so that both ends of the guide rail 32 are reliably fixed. At the same time, the connector 31 and the fixing frame 15 provide tension force to both ends of the guide rail 32, so that the guide rail 32 can be kept taut in the entire length direction, and avoid the guide rail 32 from bending or loosening.

[0053] The elongated groove design makes adjusting the tension of the guide rail 32 easier, allowing for fine-tuning during installation to ensure optimal straightness and improve installation accuracy.

[0054] Locking nuts are installed at both ends of the guide rail 32, and a butterfly spring 34 is provided between the locking nuts and the side plate of the connector 31 or the side plate of the fixing frame 15.

[0055] The locking nut securely fixes both ends of the guide rail 32 to the side plates of the connector 31 and the fixing bracket 15, preventing the guide rail 32 from loosening or shifting during use and ensuring its stability. A disc spring 34 is positioned between the locking nut and the side plate. The elastic force of the disc spring 34 compensates for the tightening force of the locking nut. Utilizing the elastic characteristics of the disc spring 34, it prevents loosening due to vibration or other factors, keeping the guide rail 32 taut and ensuring its straightness is not affected by a loose locking nut. The disc spring 34 can be any type of elastic element, such as a common cylindrical spring or a wave spring, as long as it effectively prevents loosening and compensates for the tightening force.

[0056] The locking nut and the disc spring 34 work together to ensure that the guide rail 32 is securely fixed and has an anti-loosening effect. The synergistic effect of the two ensures the reliability of the connection at both ends of the guide rail 32, allowing the guide rail 32 to maintain a stable tension state for a long time, and providing continuous protection for the smooth sliding of the moving plate 21.

[0057] like Figure 6 , Figure 9 As shown, a movable frame 22 is provided on the top of the movable plate 21. The movable plate 21 and the movable frame 22 constitute the movable assembly 2. The movable frame 22 includes a connecting plate 221 and a supporting plate 222. The connecting plate 221 is installed on the top of the movable plate 21, and the supporting plate 222 is installed on the connecting plate 221 through an elongated groove. The roller 35 is installed on the supporting plate 222. The roller 35 is installed on the movable frame 22, and the movable plate 21 slides on the guide rail 32 via the movable frame 22. The roller 35 can be made of different materials such as rubber rollers, plastic rollers, and metal rollers, as long as it can roll smoothly along the guide rail 32 and drive the movable plate 21 to move. Of course, it is understandable that the sliding of the movable plate 21 on the guide rail 32 can be achieved in various ways, not limited to using rollers. For example, a slider or sliding sleeve can be directly fixed to the movable plate 21 or connected to it through the movable frame 22. The slider or sliding sleeve overlaps or sleeves on the guide rail 32 for reciprocating sliding. The slider or sleeve is made of a material with a low coefficient of friction, such as polytetrafluoroethylene, nylon, graphite copper, etc.

[0058] The connecting plate 221 serves as the connecting component between the movable frame 22 and the movable plate 21, providing a mounting base for the support plate 222 and the roller 35. This allows the roller 35 to form a stable connection with the movable plate 21, ensuring that the roller 35 can effectively drive the movable plate 21 to slide when it rolls. The support plate 222 is mounted on the connecting plate 221 via an elongated groove. The position of the support plate 222 relative to the connecting plate 221 can be adjusted through the elongated groove, thereby adjusting the relative position between the support plate 222 and the guide rail 32, allowing the support plate 222 to better cooperate with the guide rail 32.

[0059] Furthermore, the bearing plate 222 includes an upper horizontal plate, a vertical plate, and a lower horizontal plate. The vertical plate is located between the upper horizontal plate and the lower horizontal plate, making the bearing plate 222 form a C-shaped structure. The upper horizontal plate is mounted on the connecting plate 221. The roller 35 is mounted on the inner side of the vertical plate. The guide rail 32 is located between the roller 35 and the lower horizontal plate.

[0060] The C-shaped support plate 222 forms an enclosed structural space that encloses the mating parts of the roller 35 and the guide rail 32. The lower horizontal plate is located below the guide rail 32 and can limit the roller 35, preventing it from jumping off the guide rail 32 as it rolls along it. This ensures that the mating between the roller 35 and the guide rail 32 remains stable and avoids the sliding failure of the moving plate 21 due to the roller 35 jumping off.

[0061] like Figure 6 As shown, a limit frame 36 is also provided on the fixed plate 11. The limit frame 36 is located at the left and right ends, which forms a hard limit on the sliding of the moving plate 21. A buffer block is also provided on the side of the limit frame 36 to protect the moving frame 22.

[0062] like Figure 4 , Figure 10 As shown, the guide rail 32 includes a top guide rail 32 and a bottom guide rail 32. The roller 35 rolls on the top guide rail 32. The bottom of the moving plate 21 is equipped with a limiting member 33, which slides along the bottom guide rail 32.

[0063] The guide rails 32 are configured as two sets: a top guide rail 32 and a bottom guide rail 32. The roller 35 only engages with and rolls on the top guide rail 32, providing primary rolling support for the sliding of the moving plate 21. Simultaneously, a limiting member 33 is installed at the bottom of the moving plate 21. The limiting member 33 does not participate in rolling but only slides along the bottom guide rail 32, providing a limiting and guiding function for the sliding of the moving plate 21. This prevents the moving plate 21 from flipping outwards during sliding and prevents the top roller 35 from dislodging from the guide rail 32. Dividing the guide rails 32 into top and bottom sets, with the top and bottom of the moving plate 21 engaging with the guide rails 32 respectively, forms a two-point support and guiding structure, making the sliding process of the moving plate 21 smoother and improving its safety.

[0064] Specific examples Figure 11 As shown, the limiting member 33 is generally L-shaped, including a horizontal mounting part 331 and a vertical limiting part 332. The mounting part 331 is fixed to the bottom of the moving plate 21, and the limiting part 332 has an opening groove through which the bottom guide rail 32 passes.

[0065] The mounting part 331 of the limiting member 33 is responsible for a reliable connection with the moving plate 21, and the limiting part 332 is responsible for guiding the cooperation with the bottom guide rail 32. The opening groove in the limiting part 332 cooperates with the bottom guide rail 32, allowing the limiting member 33 to slide smoothly along the bottom guide rail 32. At the same time, the structural design of the opening groove facilitates the installation and assembly of the limiting member 33 and the bottom guide rail 32. The opening groove can be snapped into the bottom guide rail 32, and the installation of the limiting member 33 can be completed without disassembling the guide rail 32, thus improving the installation efficiency. Of course, it is understandable that a through hole can also be opened on the limiting part 332 to cooperate with the guide rail 32. The structure of the through hole can provide a better limiting effect for the limiting member 33 and prevent the limiting member 33 from derailing when sliding along the guide rail 32.

[0066] The movable board 21 is usually in pairs. When viewing the multimedia screen, the user must first open one movable board 21, then walk to the other side and open the other movable board 21, which is cumbersome. In addition, it was found that due to the change in the sliding mechanism 3, the friction of the sliding mechanism 3 is smaller. When writing or drawing lines on the movable board 21 with teaching aids, the applied force easily causes the movable board 21 to slide, affecting the user experience.

[0067] Based on this, the writing board described in this embodiment also includes a linkage mechanism 4, such as... Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, the linkage mechanism 4 has two symmetrically arranged sets. The linkage mechanism 4 includes a pull wire 41 and a rotating wheel 42. The rotating wheel 42 is fixedly installed at the end of the fixed plate 11. One end of the pull wire 41 is connected to the outer side of one of the movable plates 21, and the other end of the pull wire 41 passes around the rotating wheel 42 and is connected to the inner side of the other movable plate 21. Here, the inner side refers to the side closer to the middle in the horizontal direction, and the outer side refers to the side farther away from the middle in the horizontal direction.

[0068] like Figure 12 As shown, for clarity, the two sets of linkage mechanisms 4 are displayed separately. Figure 12 The upper part of the diagram shows a set of linkage mechanisms 4. When the right movable plate 21 is closed, it is pulled to the left. At this time, the lower part of the pull cable 41 moves to the left, passes around the rotating wheel 42, and then the upper part of the pull cable 41 moves to the right, thereby driving the left movable plate 21 to move to the right, thus closing the left movable plate 21, and thus closing both movable plates 21 simultaneously. Similarly, when the right movable plate 21 is opened, as... Figure 12 As shown in the lower middle figure, the left movable plate 21 is moved to the left, thereby opening the movable plates 21 on both sides simultaneously.

[0069] Two sets of symmetrically arranged linkage mechanisms 4 cooperate with the two movable plates 21 on both sides to realize the synchronous sliding of the two movable plates 21. When one of the movable plates 21 is pushed to slide, the movable plate 21 will pull the pull line 41 connected to it. After the pull line 41 passes around the rotating wheel 42 and changes the direction of the pulling force, it will drive the other movable plate 21 to slide in the opposite direction. There is no need to operate the two movable plates 21 separately, which simplifies the operation of the movable plates 21 and improves the convenience of use.

[0070] The cooperation between the pull string 41 and the rotating wheel 42 transmits the sliding force of one movable plate 21 to the other, realizing the transmission and direction conversion of force, and creating a linkage effect between the sliding of the two movable plates 21. By linking the two movable plates 21, the damping of the movable plates 21 during sliding is increased. When writing or drawing lines on the movable plates 21 with teaching aids, the applied force is less likely to cause the movable plates 21 to slide, allowing the movable plates 21 to maintain a stable position and improving the writing and display effect. The linkage mechanism 4 makes the two movable plates 21 form a linked whole. The operation of a single movable plate 21 can realize the synchronous switching of the two movable plates 21, which simplifies the operation and improves the stability of the movable plates 21.

[0071] Specifically, the pull cable 41 can be made of different transmission components such as steel wire rope or nylon rope, as long as it can transmit the force and drive the moving plate 21 to slide. The rotating wheel 42 can be made of different rotating components such as fixed pulley or bearing roller 35, as long as it can provide rotational support for the pull cable 41 and change the direction of the pulling force.

[0072] like Figure 9 As shown, a support plate 223 is also provided on the side of the connecting plate 221 of the movable frame 22. The pull wire 41 is fixed on the support plate 223, and a through hole is provided on the support plate 223 for the pull wire 41 to pass through. Figure 7 As shown, the rotating wheel 42 is horizontally installed in the fixed frame 15, and the side plate of the fixed frame 15 has a groove for the pull wire 41 to pass through.

[0073] The support plate 223 provides a dedicated base for fixing and threading the pull wire 41, allowing the pull wire 41 to be securely connected to the moving plate 21. Simultaneously, the through-hole design allows the pull wire 41 to pass through the support plate 223 in an orderly manner, preventing tangling or misalignment and ensuring that the tension of the pull wire 41 is effectively transmitted to the moving plate 21. The groove on the side plate of the fixing frame 15 provides space for the pull wire 41 to pass through, allowing it to smoothly connect to the moving plate 21 without obstructing the pull wire and preventing wear.

[0074] like Figure 13As shown, a support frame 16 is also provided on the fixed plate 11. The support frame 16 has a fixing part and a supporting part. The fixing part is installed on the upper side of the fixed plate 11, and the supporting part has an arc-shaped structure and is supported on the bottom side of the guide rail 32.

[0075] Because the guide rail 32 is quite long, although both ends are tightened and fixed by the fixing frame 15 and the connecting piece 31 respectively, the middle part may still sag or bend due to its own weight or the pressure of the sliding plate 21. The fixing part of the support frame 16 is installed on the upper side of the fixing plate 11, using the fixing plate 11 as a stable support base. The support part has an arc-shaped structure and supports the bottom side of the guide rail 32. When the sliding plate 21 slides, the arc-shaped support part can effectively support the guide rail 32, prevent the middle part from sagging, and ensure that the guide rail 32 maintains straightness throughout its length, without hindering the sliding of the moving frame 22.

[0076] Example 2 This embodiment provides an installation method for the combined guide rail writing board as described in Embodiment 1. The writing board includes a fixing component 1, a moving component 2, a sliding mechanism 3, and a linkage mechanism 4. The fixing component 1 includes a fixing plate 11 and a fixing frame 15. The moving component 2 includes a moving plate 21 and a moving frame 22. The sliding mechanism 3 includes a connector 31, a guide rail 32, a roller 35, and a limiting component 33. The linkage mechanism 4 includes a pull wire 41 and a rotating wheel 42.

[0077] The installation method includes the following steps: Connect the two ends of the connecting strip 12 to the fixing plate 11, and install the fixing bracket 15 on the back of the fixing plate 11; install the fixing plates 11 on both sides of the wall base through the fixing bracket 15, and install the rotating wheel 42 in the outer fixing bracket 15; install the inner sealing plate 13 and the outer sealing plate 14 on both sides of the fixing plate 11; this step completes the overall installation of the fixing component 1, so that the fixing component 1 forms a stable installation base and ensures the appearance effect.

[0078] Install connector 31 on the wall base between the two fixing plates 11; this step provides a tensioning base for the installation of guide rail 32. The installation position of connector 31 is compatible with the fixing frame 15, ensuring that the guide rail 32 can be effectively tensioned after installation.

[0079] Install guide rail 32 between connector 31 and fixed frame 15; this step completes the construction of guide rail of sliding mechanism 3. The two ends of guide rail 32 are connected to connector 31 and fixed frame 15 respectively, and can be tightened through connector 31 to ensure the straightness of guide rail 32.

[0080] A movable frame 22 is installed on the top of the movable plate 21. The movable frame 22 has rollers 35. The rollers 35 are installed on the top guide rail 32. A limiting member 33 is installed on the top of the movable plate 21 and is locked onto the bottom guide rail 32. This step completes the cooperation between the movable component 2 and the sliding mechanism 3, allowing the movable plate 21 to slide through the cooperation of the rollers 35 and the limiting member 33 with the guide rail 32. At the same time, the locking of the limiting member 33 ensures the stability of the sliding.

[0081] One end of the pull wire 41 is connected to the outside of one of the movable plates 21, and the other end of the pull wire 41 is connected to the inside of the other movable plate 21 after passing around the rotating wheel 42. This step completes the assembly of the linkage mechanism 4 and realizes the synchronous linkage of the two movable plates 21.

[0082] This installation method first completes the installation of the fixed foundation, then the assembly of the moving parts, and finally the connection of the linkage mechanism 4. It changes the traditional installation process of the writing board structure, simplifies the installation operation, facilitates on-site installation, improves installation efficiency, and ensures that all functions of the writing board can be realized normally after installation.

[0083] While the specific embodiments of the present invention have been described above, they are not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
