Description

Technical Field

[0001] This utility model relates to the field of writing board technology, and in particular to a splicing writing board. Background Technology

[0002] In spaces such as large conference rooms, lecture halls, training centers, or exhibition venues, standard-sized writing boards often fall short of the needs for large-area writing and display. To address this, modular writing boards have emerged, combining two or more independent writing board units to form a single, large-sized writing wall. This design not only solves the need for extra-large writing surfaces but also offers greater convenience and flexibility in transportation, handling, and installation compared to single, giant writing boards of the same size. Therefore, the rationality of its connection structure, ease of installation, and overall stability are the core of its design.

[0003] In existing technologies, the assembly of modular writing boards typically relies on a standardized set of fasteners and connectors. A common implementation involves first placing individual writing board supports side-by-side, then using separate connecting plates or metal strips, bolts, nuts, and washers are used to thread and lock them together through pre-drilled holes in the supports and connecting plates, thus fixing multiple supports into a single frame. Subsequently, the writing board body is secured to the assembled modular support frame again using screws or bolts through mounting holes on its frame. Angle adjustment and fixing are usually achieved through joints with toothed meshing structures or through friction plates with high-pressure locking; tightening these structures also requires the use of tools such as wrenches to apply sufficient torque to the center bolt.

[0004] However, the common connection methods in the aforementioned existing technologies have significant drawbacks in actual installation. The core problem lies in the cumbersome assembly process and strong dependence on various installation tools. Specifically, when assembling the bracket frame, installers may need to use a wrench to tighten the bolts and nuts of the connecting plates; while when fixing the writing board body to the bracket, a screwdriver is needed to tighten the fixing screws. This operation method, which requires frequent switching of installation tools between different steps, not only greatly reduces installation efficiency and prolongs deployment time, but also increases the risk of installation interruption due to tool incompatibility or loss of small parts, making the entire splicing process cumbersome and inconvenient. This is particularly prominent in situations requiring rapid assembly or disassembly, thus weakening the convenience and practicality that the splicing writing board should possess to a certain extent. Therefore, a splicing writing board is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a modular writing board, aiming to improve the drawbacks of existing modular writing boards, which are cumbersome to install and overly reliant on tools. Assembly requires frequent switching between tools such as wrenches and screwdrivers, which not only significantly reduces installation efficiency but also increases the risk of interruption due to lost tools. This cumbersome process diminishes the convenience and practicality that the product should possess.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a splicing writing board, comprising two supports, universal wheels provided on the lower surface of the supports, a writing board body provided between the two supports, left and right symmetrical hanging rings slidably connected to the upper surface of the writing board body, a placement plate slidably connected to one side of the outer wall of the writing board body, and a connecting component provided on one side of the supports;

[0007] The connecting assembly includes a mounting sleeve, one side of the outer wall of the mounting sleeve is fixedly connected to one side of the outer wall of the bracket, a crossbar is slidably connected inside the mounting sleeve, a rotating shaft is rotatably connected inside the bracket, a clamping plate is fixedly connected to one end of the rotating shaft, the inner wall of the clamping plate abuts against the outer wall of the writing board body, an adjusting bolt is threaded inside the rotating shaft, a spring is fixedly connected to one side of the inner wall of the adjusting bolt, a positioning piece is fixedly connected to one end of the spring, and an adjusting bolt is threaded inside the clamping plate.

[0008] As a further description of the above technical solution:

[0009] A sleeve is fixedly connected to one side of the outer wall of one of the brackets, and a connecting shaft is fixedly connected to one side of the outer wall of the other bracket.

[0010] As a further description of the above technical solution:

[0011] An extension rod is fixedly connected to one end of the connecting shaft, and a positioning hole is provided inside the extension rod.

[0012] As a further description of the above technical solution:

[0013] A protrusion is fixedly connected to the outer wall of the sleeve, and a T-shaped rod is slidably connected inside the protrusion.

[0014] As a further description of the above technical solution:

[0015] One end of the T-shaped rod is fixedly connected to a locking block, and a spring is sleeved on the outer wall of the T-shaped rod.

[0016] As a further description of the above technical solution:

[0017] A lever is rotatably connected to one side of the outer wall of the T-shaped rod, and an anti-slip strip is fixedly connected to one side of the outer wall of the lever.

[0018] As a further description of the above technical solution:

[0019] The outer wall of the extension rod is slidably connected to the inner wall of the sleeve, and the outer wall of the locking block is slidably connected to the inner wall of the positioning hole.

[0020] As a further description of the above technical solution:

[0021] One side of the outer wall of the positioning piece abuts against one side of the outer wall of the bracket, and one end of the adjusting bolt abuts against one side of the outer wall of the writing board body.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by placing the crossbar in the mounting sleeve on one side of the two supports, a quick and stable connection is achieved. Then, by placing the writing board body on one side of the card plate and fixing it with adjusting bolt two to prevent it from falling off, and by rotating adjusting bolt one to make the positioning piece close to one side of the support, the angle of the writing board body is further fixed. This solves the problem of needing to frequently switch installation tools for the splicing of existing writing boards, thereby improving the practicality of the writing board.

[0024] 2. In this utility model, by turning the lever on the outer wall of the protrusion, the T-shaped rod is driven to move the locking block, thereby achieving the effect of retracting the second spring. Then, by inserting the extension rod into the sleeve through the connecting shaft, and then by turning the locking block to reset, the locking block is driven to engage in the positioning hole by the reaction force of the second spring. According to the different positioning holes, the spacing between the brackets can be easily adjusted to adapt to the size of the writing board body, thereby improving the practicality of the writing board.

[0032] 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.

[0033] Reference Figures 1-5 The present invention provides an embodiment of a splicing writing board, comprising two supports 1 as the supporting base of the overall structure. The lower surface of the supports 1 is provided with casters 2 for easy movement and positioning. The writing board body 10, which serves as the core for writing and display, is provided between the two supports 1. The upper surface of the writing board body 10 is slidably connected with hanging rings 11 arranged symmetrically on the left and right for hanging drawings or documents. A placement plate 12 that can extend out to place tools is slidably connected to one side of the outer wall of the writing board body 10. A set of connecting components for splicing and fixing is provided on one side of the supports 1.

[0034] The connecting assembly includes a mounting sleeve 3, which serves as a base for the connecting crossbar 4. One side of the outer wall of the mounting sleeve 3 is fixedly connected to one side of the outer wall of the bracket 1, while the interior of the mounting sleeve 3 is slidably connected to the crossbar 4, which connects the two brackets 1. Inside the bracket 1, a rotating shaft 6 is rotatably connected to support the writing tablet body 10 and allows for angle adjustment. One end of the rotating shaft 6 is fixedly connected to a clamping plate 5 for supporting the writing tablet body 10, and the inner wall of the clamping plate 5 abuts against the outer wall of the writing tablet body 10. The rotating shaft 6 is internally threaded with an adjusting bolt 7 for angle locking. One side of the inner wall of the adjusting bolt 7 is fixedly connected to a spring 8 for buffering and transmission, and the other end of the spring 8 is fixedly connected to a positioning piece 9 for final locking. The clamping plate 5 is internally threaded with an adjusting bolt 13 for clamping the writing tablet body 10. In the locked state, one side of the outer wall of the positioning piece 9 abuts against one side of the outer wall of the bracket 1, and one end of the adjusting bolt 13 abuts against one side of the outer wall of the writing tablet body 10 to apply clamping force.

[0035] Specifically, during installation, first insert the horizontal frame 4 into the mounting sleeves 3 of the two side supports 1 to complete the basic connection. Then, place the writing board body 10 on the clamping plate 5 and tighten the adjusting bolt 13 to secure it firmly. When it is necessary to adjust the writing angle, the writing board body 10 and its driven shaft 6 can be rotated freely. After selecting the angle, tighten the adjusting bolt 7. This bolt, through the spring 8, pushes the positioning piece 9 to press tightly against the side wall of the support 1, using friction to reliably lock the angle.

[0036] Reference Figures 1-5 A sleeve 14, serving as a guide sleeve for the telescopic mechanism, is fixedly connected to one side of the outer wall of one bracket 1, while a connecting shaft 15, which mates with the other bracket 1, is fixedly connected to one side of the outer wall of the other bracket 1. An extension rod 16 for realizing the telescopic stroke is fixedly connected to one end of the connecting shaft 15. The extension rod 16 has multiple positioning holes 17 for positioning along its length. A protrusion 18 for installing a locking component is fixedly connected to the outer wall of the sleeve 14. A T-shaped locking pin actuator is slidably connected inside the protrusion 18. Rod 19; One end of the T-shaped rod 19 is fixedly connected to a locking block 20 for engaging with the positioning hole 17, and a spring 21 providing a restoring elastic force is sleeved on its outer wall; To facilitate manual operation, a toggle piece 22 is rotatably connected to one side of the outer wall of the T-shaped rod 19, and an anti-slip strip 23 for anti-slip function is further fixedly connected to one side of the outer wall of the toggle piece 22; In terms of structural assembly, the outer wall of the extension rod 16 and the inner wall of the sleeve 14 form a sliding connection, and the outer wall of the locking block 20 is used to form a sliding engagement with the inner wall of the positioning hole 17.

[0037] Specifically, when the spacing needs to be adjusted, the user can move the lever 22 with the anti-slip strip 23. Through its leverage, the T-shaped rod 19 is pulled to overcome the elasticity of the second spring 21, causing the locking block 20 to disengage from the current positioning hole 17 and release the lock. At this time, the user can freely stretch or compress the two supports 1, allowing the extension rod 16 to slide within the sleeve 14 until the desired spacing is achieved. After selecting a suitable positioning hole 17 and aligning it with the locking block 20, the lever 22 is released. The pre-stored elasticity of the second spring 21 will automatically push the T-shaped rod 19 back to its original position, causing the locking block 20 to re-insert into the positioning hole 17. This completes the quick and reliable locking of the spacing of the supports 1, adapting to different sizes of writing tablet bodies 10.

[0038] Working principle: When the writing tablet is needed, firstly, insert both ends of the crossbar 4 into the mounting sleeves 3 on one side of the two supports 1 to achieve a quick basic connection between the two supports 1. Then, place the writing tablet body 10 onto the clamping plate 5 driven by the rotating shaft 6. By rotating the adjusting bolt 13 on the clamping plate 5, its end abuts against the outer wall of the writing tablet body 10, thereby clamping and fixing it to prevent it from accidentally falling off. When it is necessary to fix the writing angle of the writing tablet body 10, the adjusting bolt 7 inside the rotating shaft 6 can be rotated. The rotation of this bolt will cause axial displacement, which in turn pushes the positioning piece 9 through the spring 8, so that the outer wall of the positioning piece 9 is tightly pressed against one side of the outer wall of the support 1. The friction generated is used to prevent the rotation of the rotating shaft 6, thereby stably locking the writing tablet body 10 at the required angle.

[0039] Secondly, when it is necessary to adjust the distance between the two supports 1 according to the size of the writing tablet body 10, the user first moves the lever 22 on one support 1. The rotation of the lever 22 will cause the T-shaped rod 19 to slide, causing the locking block 20 to disengage from the positioning hole 17 of the extension rod 16, while compressing the second spring 21. At this time, the connection is unlocked, and the user can stretch or push the support 1 with the connecting shaft 15 relative to the other support 1 with the sleeve 14 to adjust the spacing. When the other positioning hole 17 on the extension rod 16 moves to the position of the locking block 20, the lever 22 is released, and the reaction force of the second spring 21 will push the T-shaped rod 19 to reset, causing the locking block 20 to automatically engage in the new positioning hole 17, thereby completing the quick adjustment and locking of the spacing between the supports 1.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
