[0030] Embodiment 1:

[0031] like Figures 1 to 6As shown, the combined wall writing board includes a writing board body 1, wherein the writing board body 1 includes at least one unit writing board 2, wherein the unit writing board 2 includes a writing surface 3 and a supporting frame, a limiting frame 4 is arranged on the peripheral side of the supporting frame, and the edge of the writing surface 3 is clamped between the limiting frame 4 and the supporting frame.

[0032] By setting a limit frame 4 to clamp and fix the edge of the writing surface 3, the occupation of the area of ​​the writing surface 3 by the traditional frame is avoided. The limit frame 4 is set on the surrounding side of the unit writing board 2 to limit the writing surface 3 from the side. At the same time, the limit frame 4 is inserted into the supporting frame to be hidden, so as to achieve the purpose of no frame, ensuring that the writing surface 3 has sufficient writing area. At the same time, when multiple unit writing boards 2 are combined into the writing board body 1, the writing surfaces 3 of adjacent unit writing boards 2 are seamlessly connected, which ensures the integrity of the writing surface 3 after combination, facilitates writing display, and improves flexibility and practicality of use.

[0033] In the combined wall writing board of this embodiment, the support frame is provided with a clamping groove 5 , and the limit frame 4 is provided with a clamping leg 6 close to the support frame, and the clamping leg 6 is clamped in the clamping groove 5 .

[0034] The provision of a snap-fit ​​structure facilitates the disassembly and assembly of the unit writing board 2, avoids the complex operation of multiple parts of other fixed structures, and simplifies the writing board structure; specifically, the width of the snap-fit ​​groove 5 on the side away from the limiting frame 4 is larger to form a limiting snap-fit ​​groove, and a protrusion is provided on the side of the corresponding snap-fit ​​leg 6, and fixation is achieved by the cooperation of the protrusion and the limiting snap-fit ​​groove.

[0035] Preferably, two clamping legs 6 are relatively arranged on the limiting frame 4, and the protrusions on the two clamping legs 6 are arranged on the side away from each other. The two clamping legs 6 cooperate with the clamping groove 5 to increase the clamping fixing strength, thereby ensuring the fixing effect on the edge of the writing surface 3.

[0036] Preferably, the surface of the limiting frame 4 is perpendicular to the surface of the unit writing board 2. By setting it as a vertical structure, it is convenient to achieve seamless combination when splicing multiple unit writing boards 2, thereby improving the integrity of the writing surface 3.

[0037] In the combined wall writing board of this embodiment, a first inclined surface is provided on the side of the limit frame 4 close to the supporting frame, and a second inclined surface is provided on the supporting frame. The first inclined surface and the second inclined surface are fitted together to clamp the writing surface 3.

[0038] Specifically, two mutually fitting inclined surfaces are realized, and the edge of the writing surface 3 is bent toward the center of the unit writing board 2. At the same time, the bending angle is fixed. The fixing strength of the limit frame 4 on the writing surface 3 is improved through the bending structure, which prevents the edge of the writing surface 3 from escaping from the gap between the limit frame 4 and the supporting frame and affecting normal use.

[0039] In the combined wall writing board of this embodiment, the support frame includes a frame 7, and the frame 7 is provided with multiple frames and evenly distributed on the edge of the unit writing board 2, and the writing surface 3 is clamped between the frame 7 and the limit frame 4.

[0040] Specifically, four frames 7 are provided, and the frames 7 are located below the writing surface 3, and the outer edges are tightly fitted with the bending part of the writing surface 3. The above-mentioned arrangement ensures that the frames 7 provide support for the writing surface 3 while avoiding the damage of the traditional frames 7 to the writing surface 3, thereby maximizing the writing surface 3, realizing a frameless structure, and improving the practicality of the writing board.

[0041] In the combined wall writing board of this embodiment, the support frame further comprises an insertion corner 8, and the insertion corner 8 is provided with two insertion strips 9, and the two insertion strips 9 are respectively inserted into two adjacent frames 7 to form a support frame.

[0042] Specifically, four plug-in corners 8 are provided to fix four frames 7 from four top corners of the unit writing board 2, so as to realize stable connection of the support frame, thereby ensuring the support strength. The plug-in strips 9 on both sides are respectively plugged with the frames 7 on both sides of the same top corner, so as to realize the sequential connection of the frames 7.

[0043] In the combined wall writing board of this embodiment, the two plug-in strips 9 are symmetrically arranged about the connecting plate 10, and the plug-in strips 9 include a first plug-in strip and a second plug-in strip, and the end of the frame 7 is provided with a first plug-in groove and a second plug-in groove.

[0044] Specifically, the connecting plate 10 is arranged at the joint of the plug-in strips 9, and the plug-in strips are arranged as two sub-plug-in strips, so as to increase the plug-in connection strength between the plug-in corners 8 and the frame 7, ensure the strength of the supporting frame, and provide stable support.

[0045] Preferably, the first plug-in strip and the second plug-in strip are integrally formed and have a Z-shaped cross section. The above structure ensures the strength of the plug-in connection while reducing the overall size of the plug-in strip 9, making the supporting frame structure more compact and simple.

[0046] In the combined wall writing board of this embodiment, an angle is set between the plug-in strip 9 and the connecting plate 10 , and the end of the frame 7 is inclined and the inclination angle matches the angle to fit the connecting plate 10 .

[0047] Specifically, the two plug-in strips 9 are perpendicular to each other, and the end face of the frame 7 fits with the surface of the connecting plate 10. While the plug-in strips 9 and the plug-in slots cooperate, the connecting plate 10 itself clamps and limits the frame 7, further improving the connection strength of the supporting frame.

[0048] In the combined wall writing board of this embodiment, a locking groove 12 into which a locking buckle 11 can be inserted is provided on the supporting frame. The locking buckle 11 includes two locking plates, which are inserted into the locking grooves 12 of two adjacent unit writing boards 2 to form a writing board body 1.

[0049] Specifically, the locking buckle 11 is U-shaped, and the length of the locking buckle 11 matches the spacing between the locking grooves 12 on two adjacent unit writing boards 2. The two adjacent unit writing boards 2 are locked by plugging the locking plate into the locking groove 12, so that the unit writing boards 2 are combined into the writing board body 1.

[0050] Specifically, a groove is provided on one side of the frame 7 away from the writing surface 3 , and a locking groove 12 is provided in the groove so that the locking groove 12 has a certain depth, thereby ensuring the connection strength between the unit writing boards 2 .

[0054] Specifically, the hanger 13 is L-shaped, one end of which is threadedly connected to the clip nut, and the other end is provided with a through hole matching the fixing piece. Preferably, the through hole is a horizontal long hole, which facilitates the fixing piece to slide in the through hole to achieve fine adjustment of the position.

[0055] Specifically, the hanging part 13 is horizontally slidably connected to the tablet body 1 by the cooperation of the clip nut and the upper frame of the tablet body 1. After installation, it can be moved left and right for adjustment. The clip nut is rotated to push the support frame to move in the vertical direction to achieve appropriate height adjustment, which has high flexibility.

[0056] Preferably, the hanger 13 can also be set to be fixed with an adhesive structure, or use a traceless nail structure, an aluminum profile structure, or a toothed hanger structure.

[0057] In the combined wall writing board of this embodiment, a tripod 14 is provided at the corner of the supporting frame, a hanging hole 15 for hooking is provided on the tripod 14, and a hanging tooth 16 for hooking is provided at the edge of the tripod 14.

[0058] Specifically, triangular special-shaped hangers are arranged at the corners of the supporting frame, and the hanging holes 15 on the tripod 14 include a plurality of connected large holes and small holes. When hanging, the fixing part is first inserted into the large hole and then slides into the small hole, and the end of the fixing part is limited to achieve hanging and fixing; in addition, the serrated hanging teeth 16 enable the fixing part on the wall to be snapped into the teeth at different positions to fix the writing board. The above arrangement reduces the accuracy requirements for the position of the fixing part when installing the writing board, and improves practicality.

[0059] Preferably, the tripod 14 is fixedly connected to the connecting plate 10 in the plug-in corner 8 to improve the overall connection strength and facilitate the installation of the tripod 14 .

[0060] Preferably, in the combined wall writing board of this embodiment, a limiting buckle structure is also provided, including a first limiting block 17 and a second limiting block. An insert tongue 18 is provided at one end of the first limiting block 17 close to the second limiting block, and the surface of the insert tongue 18 has convex teeth. A limiting buckle 19 is provided on the second limiting block, and the combined connection of the two unit writing boards 2 is realized by inserting the insert tongue 18 into the limiting buckle 19.

[0061] Preferably, a plug-in rod is provided on one side of the first limiting block 17 and the second limiting block close to the frame 7, and the limiting is achieved by connecting the first limiting block 17 and the frame 7 through the plug-in rod.
