Description

Technical Field

[0001] This utility model relates to the field of whiteboard holder technology, and more specifically, to a self-cleaning whiteboard holder. Background Technology

[0002] In today's teaching, meeting discussions, and personal and family note-taking scenarios, whiteboards are widely used as a rewritable writing tool. With their advantages of being clean and pollution-free, and providing clear writing, whiteboards are gradually replacing traditional chalk and blackboards.

[0003] However, in practical use, existing whiteboards present significant challenges. Whether in school classrooms where teachers frequently erase whiteboard writing after explaining concepts to continue writing new material, or in corporate meetings where participants manually erase after presenting their viewpoints, this process is time-consuming and energy-intensive. In fast-paced meetings, the inefficiency of manual erasing can hinder the smooth progress of subsequent sessions. Furthermore, during manual erasing, users are susceptible to coming into contact with whiteboard ink, staining their clothing. For those engaged in teaching or frequent whiteboard use, repeated manual erasing can lead to wrist fatigue. Additionally, the contact pressure between the eraser and the whiteboard surface during manual erasing relies entirely on tactile feedback; uneven pressure can result in residual writing, severely impacting the clarity and visual appeal of subsequent writing. In business meetings or academic presentations where high presentation quality is required, an unclean whiteboard can reduce the quality of information delivery and affect communication. This often requires operators to wipe the whiteboard multiple times, constantly moving to cover the entire writing area. This process is cumbersome, especially when multiple people are using the whiteboard continuously. Frequent and inefficient erasing can severely disrupt the continuity of information exchange and reduce overall work efficiency.

[0004] Therefore, in order to overcome the problems of low efficiency and inconvenience in manually erasing writing on whiteboards, it has become an urgent need in practical applications to develop a whiteboard holder that can automatically erase writing, thereby improving the convenience and efficiency of whiteboard use.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figures 1 to 9 As shown, this utility model provides a self-cleaning whiteboard holder, comprising: A fixed frame 1 is provided, and a white board 2 is provided on the fixed frame 1. The white board 2 is connected to the fixed frame 1 by bolts. A slide rail 3 is fixedly sleeved on the outer surface of the fixed frame 1. A fixed plate 4 is fixedly installed on the outer surface of the slide rail 3. A protective shell 5 is fixedly installed on the top of the fixed plate 4. The motion mechanism is located inside the protective shell 5; The motion mechanism includes a short shaft 6, the outer surface of which is movably connected to the inner surface of the outer surface of the protective shell 5. A gear 7 is fixedly sleeved on the outer surface of the short shaft 6, and a rack 8 is meshed on the outer surface of the gear 7. A rotating rod 9 is fixedly sleeved at the front end of the short shaft 6. A pressing shaft 10 is fixedly sleeved at the end of the rotating rod 9 away from the short shaft 6. A moving block 11 is slidably connected to the outer surface of the pressing shaft 10. A movable block 12 is fixedly installed on the outer surface of the moving block 11. The bottom end of the movable block 12 is slidably connected to the inner surface of the slide rail 3. An erasing block 13 is fixedly installed on the movable block 12. The fixed frame 1 provides a mounting carrier for the whiteboard 2. The whiteboard 2 is connected to the fixed frame 1 by bolts to achieve a stable assembly. The slide rail 3 is fixedly sleeved on the outer surface of the fixed frame 1, providing guidance for the sliding of the movable block 12 and ensuring the smooth movement of the movable block 12. The fixed plate 4 is fixed on the outer surface of the slide rail 3 to support the protective shell 5, which in turn protects the internal moving mechanism components. The short shaft 6 in the moving mechanism is movably sleeved inside the protective shell 5, providing a mounting and rotation fulcrum for the gear 7. The gear 7 meshes with the rack 8, converting the linear motion of the rack 8 into its own rotational motion. The rotating rod 9 is fixed to the short shaft 6 and can rotate synchronously with the short shaft 6. When the pressing shaft 10 rotates with the rotating rod 9, it can push the moving block 11 to move. The moving block 11 drives the movable block 12 to slide along the slide rail 3, thereby causing the erasing block 13 on the movable block 12 to move and erase the writing on the whiteboard 2.

[0015] Among them, the inner sliding connection of the rack 8 is the limiting block 16 on the outer surface, and the limiting block 16 is fixedly connected to the inner part of the protective shell 5. The limiting block 16 is fixedly connected to the inside of the protective shell 5 and slidably connected to the inside of the outer surface of the rack 8. Its function is to restrict the movement direction of the rack 8, ensuring that the rack 8 can only move up and down along the set direction, preventing the rack 8 from deviating during the movement, and ensuring that the rack 8 and the gear 7 always maintain a stable meshing state, so that the motion mechanism can transmit power normally.

[0016] Among them, a motor 14 is fixedly installed at the bottom of the fixed plate 4, and a lead screw 15 is fixedly sleeved at the output end of the motor 14. The outer surface of the lead screw 15 is movably sleeved with the inside of the fixed plate 4 and the protective shell 5, and the outer surface of the lead screw 15 is sleeved with the internal thread of the rack 8. The motor 14 provides power for the operation of the entire motion mechanism. The lead screw 15, which is fixed at its output end, rotates under the drive of the motor 14. Since the outer surface of the lead screw 15 is threaded with the internal thread of the rack 8, the rotation of the lead screw 15 can be converted into the linear motion of the rack 8.

[0017] The outer surface of the fixed frame 1 is fixedly installed with a positioning block 19, and the outer surface of the positioning block 19 abuts against the outer surface of the whiteboard 2.

[0018] The positioning block 19 is fixedly installed on the outer surface of the fixed frame 1 and abuts against the outer surface of the whiteboard 2. During the process of connecting the whiteboard 2 and the fixed frame 1 with bolts, the positioning block 19 can position the whiteboard 2 to ensure the accuracy and consistency of the whiteboard 2 during installation and prevent the whiteboard 2 from shifting during installation.

[0019] Among them, a lifting block 17 is fixedly installed on the outer surface of the fixed frame 1, a fixed frame 18 is slidably connected to the outer surface of the lifting block 17, a fixed rod 20 is fixedly installed at the bottom end of the fixed frame 18, and a universal wheel 21 is fixedly installed at the bottom end of the fixed rod 20. The lifting block 17 is fixed on the outer surface of the fixed frame 1 and is slidably connected to the inside of the fixed frame 18. The fixed frame 18 provides guidance and support for the movement of the lifting block 17, so that the fixed frame 1 can be raised and lowered smoothly. The fixed rod 20 is fixed at the bottom of the fixed frame 18 and is used to connect the caster wheel 21. The caster wheel 21 allows the entire whiteboard frame to move flexibly and is convenient to adjust its position in different scenarios.

[0020] Among them, a reinforcing rod 22 is fixedly installed at the top of the fixing rod 20, and the end of the reinforcing rod 22 away from the fixing rod 20 is fixedly connected to the outer surface of the fixing frame 18. One end of the reinforcing rod 22 is fixed to the top of the fixed rod 20, and the other end is fixed to the outer surface of the fixing frame 18. Through this connection method, the reinforcing rod 22 can enhance the connection strength and structural stability between the fixed rod 20 and the fixing frame 18.

[0021] Among them, a fixing beam 23 is fixedly sleeved on the outer surface of the fixing frame 18, and a bidirectional screw 24 is movably sleeved inside the fixing beam 23. A turning block 30 is fixedly installed on the left end of the bidirectional screw 24.

[0022] The fixed beam 23 is fixedly sleeved on the outer surface of the fixed frame 18, providing installation space and support for the bidirectional screw 24. The bidirectional screw 24 is movably sleeved inside the fixed beam 23 and can rotate within the fixed beam 23. The turning block 30 is fixed to the left end of the bidirectional screw 24, and the operator can drive the bidirectional screw 24 to rotate by turning the turning block 30.

[0023] The outer surface of the bidirectional screw 24 is threaded with a slider 25, and the outer surface of the slider 25 is slidably connected to the inside of the fixed beam 23. The slider 25 is threadedly connected to the outer surface of the bidirectional screw 24 and is slidably connected to the inside of the fixed beam 23. When the bidirectional screw 24 rotates, the slider 25 can slide along the inside of the fixed beam 23 under the action of the bidirectional screw 24.

[0024] The top of the slider 25 is fixedly mounted with a hinge block 26, and a movable rod 27 is hinged to the hinge block 26. A fixed shaft 28 is movably sleeved at the end of the movable rod 27 away from the hinge block 26. A connecting block 29 is fixedly mounted at the rear end of the fixed shaft 28. The top of the connecting block 29 is fixedly connected to the bottom of the fixed frame 1.

[0025] The hinge block 26 is fixed to the top of the slider 25, providing a hinge point for the movable rod 27, allowing the movable rod 27 to rotate around the hinge block 26. The end of the movable rod 27 away from the hinge block 26 is movably connected to the connecting block 29 through the fixed shaft 28. The top of the connecting block 29 is fixed to the bottom of the fixed frame 1. When the slider 25 drives the hinge block 26 to move, the movable rod 27 can push or pull the connecting block 29 through the fixed shaft 28, thereby driving the fixed frame 1 and the whiteboard 2 to rise and fall.

[0026] Working principle and usage process of this utility model: When the operator needs to use the self-cleaning whiteboard holder, they can first adjust the height of the whiteboard 2 according to their needs. Then, the operator turns the turning block 30. Since the turning block 30 is fixedly connected to the bidirectional screw 24, the bidirectional screw 24 will rotate inside the fixed beam 23 under the action of the turning block 30. Because the outer surface of the bidirectional screw 24 is threadedly connected to the inner thread of the slider 25, and the slider 25 is slidably connected to the inner thread of the fixed beam 23, the two sliders 25 will move in opposite directions along the inner thread of the fixed beam 23 under the action of the rotation of the bidirectional screw 24. At this time, the two hinge blocks 26 will move synchronously with the two sliders 25, thereby driving the two movable rods 27 to move around the hinge block 26 as the fulcrum. Since the end of the movable rod 27 away from the hinge block 26 The fixed shaft 28 is movably connected to the connecting block 29, and the connecting block 29 is fixedly connected to the fixed frame 1. Therefore, the movable rod 27 will exert an upward pushing force on the connecting block 29 during the movement. At this time, the fixed frame 1 will move upward under the drive of the connecting block 29. At the same time, the lifting block 17 on the fixed frame 1 will slide along the inside of the fixed frame 18. Due to the limiting effect of the fixed frame 18 on the lifting block 17, the fixed frame 1 will rise smoothly, thereby driving the whiteboard 2 to rise. When the whiteboard 2 reaches the appropriate height, the turning block 30 can be stopped. If it is necessary to lower the height of the whiteboard 2, the turning block 30 is turned in the opposite direction. The two sliders 25 will move towards each other, and the movable rod 27 will pull the connecting block 29 downward. The fixed frame 1 will also fall, thereby realizing the adjustment of the height of the whiteboard 2.

[0027] During use, when it is necessary to erase the writing on the whiteboard 2, the operator starts the motor 14. The motor 14 drives the lead screw 15 to rotate. Since the outer surface of the lead screw 15 is threaded with the internal thread of the rack 8, and the rack 8 is slidably connected to the limit block 16, the rotation of the lead screw 15 will drive the rack 8 to move up and down along the outer surface of the limit block 16. When the rack 8 moves downward under the drive of the lead screw 15, since the rack 8 is meshed with the gear 7, the downward movement of the rack 8 will drive the two short shafts 6 to rotate in the opposite direction through the two gears 7. At this time, the two short shafts 6 will drive the two pressing shafts 10 to perform circular motion through the two rotating rods 9. Since the pressing shafts 10 are slidably connected to the moving block 11, and the moving block 11 is also slidably connected to the movable block 11, the two short shafts 10 will drive the two pressing shafts 10 to perform circular motion. Block 12 is fixedly connected, and movable block 12 is slidably connected to slide rail 3. Therefore, during the rotation of extrusion shaft 10, it will generate a thrust on moving block 11. At this time, the two moving blocks 11 will drive the two movable blocks 12 to move towards each other along the inside of slide rail 3. At the same time, erasing block 13 on movable block 12 will move synchronously with movable block 12 and contact the surface of whiteboard 2, thereby erasing the writing on whiteboard 2. When the two movable blocks 12 move to contact each other, motor 14 controls lead screw 15 to rotate in the opposite direction, rack 8 will move upward, driving gear 7, short shaft 6, rotating rod 9 and extrusion shaft 10 to move in the opposite direction, so that the two movable blocks 12 move away from each other along slide rail 3, and erasing block 13 will also reset, completing one automatic erasing process.

[0028] Furthermore, in practical use, considering the transmission accuracy of the bidirectional screw 24 and the slider 25, a dustproof brush or other dustproof components can be added to the top of the fixed beam 23. These dustproof components can effectively prevent dust and other impurities from the external environment from entering the interior of the fixed beam 23, and prevent impurities from adhering to the threaded surface of the bidirectional screw 24 or the sliding contact surface of the slider 25. This reduces the jamming and wear between the bidirectional screw 24 and the slider 25 caused by the accumulation of impurities, and ensures the transmission efficiency and service life of both.
