[0028] As Figure 1 , 2 , Figures 3 and 4 show a sliding writing board of the present utility model, which includes a support base 10, a sliding seat 20, an outer frame 30, and a panel 40. A guide rail extending along a straight line is provided on the support base 10, and the straight line can be in the front-rear direction, up-down direction, or left-right direction. The sliding seat 20 is slidably installed on the guide rail so that the sliding seat 20 can move linearly relative to the support base 10. The outer frame 30 includes an upper frame 31 and a lower frame 32, and the upper frame 31 and the lower frame 32 are fixedly connected together in a detachable manner. An annular receiving groove is formed between the upper frame 31 and the lower frame 32, and the edge of the panel 40 is clamped in the receiving groove. The upper frame 31 and the lower frame 32 clamp the edge of the panel 40 to make the panel 40 fixedly cooperate with the outer frame 30. The front surface of the panel 40 is a surface for writing. A connecting plate 33 is provided on the lower frame 32, and the two ends of the connecting plate 33 are respectively connected to two opposite sides of the lower frame 32. An installation plate 21 located between the connecting plate 33 and the panel 40 is provided on the sliding seat 20. The installation plate 21 is clamped between the connecting plate 33 and the panel 40. A clamping structure is provided between the installation plate 21 and the connecting plate 33 to connect the installation plate 21 and the connecting plate 33 together, limiting the degree of freedom of movement of the installation plate 21 relative to the connecting plate 33 in a plane parallel to itself, and clamping the installation plate 21 by the connecting plate 33 and the panel 40 to limit the degree of freedom of movement of the installation plate 21 relative to the connecting plate 33 in its own normal direction. In this way, the installation plate 21 is kept relatively fixed with respect to the panel 40, that is, the panel 40 is fixedly installed on the sliding seat 20.

[0029] When the utility model is assembled, the mounting plate 21 is placed above the connecting plate 33, and the mounting plate 21 and the connecting plate 33 are connected by a clamping structure. Then, the panel 40 is placed above the mounting plate 21, the upper frame 31 is placed on the panel 40, and the upper frame 31 and the lower frame 32 are fixedly assembled together. While the upper frame 31 and the lower frame 32 clamp and fix the panel 40, the panel 40 and the connecting plate 33 clamp the mounting plate 21. Thus, when the upper frame 31 and the lower frame 32 are assembled, the upper frame 31, the panel 40, the mounting plate 21 and the lower frame 32 are fixed together at one time. The overall structure is relatively simple and easy to assemble, which is beneficial to the large-scale production and manufacturing of the sliding writing board.

[0030] In the preferred embodiment, the clamping structure includes a clamping groove 331 and a clamping boss 211. The clamping boss 211 is embedded in the clamping groove 331. The clamping groove 331 is arranged on the connecting plate 33, and the clamping boss 211 is arranged on the mounting plate 21. In other embodiments, the clamping groove 331 can also be arranged on the mounting plate 21, and the corresponding clamping boss 211 is arranged on the connecting plate 33.

[0031] In the preferred embodiment, the mounting plate 21 can be arranged on one side of the sliding seat 20, and a connecting plate 33 corresponding to the mounting plate 21 is arranged on the lower frame 32, so that the matching relationship between the outer frame 30 and the sliding seat 20 is relatively small, which is convenient for quick assembly. In other embodiments, two mounting plates 21 can also be respectively arranged on both sides of the sliding seat 20, and two connecting plates 33 are arranged on the lower frame 32. The two connecting plates 33 are arranged at a certain distance apart, and the sliding seat 20 is placed between the two connecting plates 33. In this way, the two mounting plates 21 are respectively matched with the two connecting plates 33 and placed above the two connecting plates 33. The clamping boss 211 protrudes downward from the lower surface of the mounting plate 21, and the clamping groove 331 penetrates through the upper and lower surfaces of the connecting plate 33.

[0032] The above-mentioned support seat 10 is arranged in a plate-like structure. Two downwardly extending sliders 22 are arranged on the sliding seat 20. A chute 23 with open front and rear ends and a bottom is formed between the two sliders 22. The support seat 10 is slidably embedded in the chute 23, and the top surface of the support seat 10 abuts against the lower surface of the lower frame 32. The above-mentioned guide rail includes two guide grooves 11 extending along a straight line. The two guide grooves 11 are respectively located at positions above the two side surfaces 101 of the support seat 10. Two pulleys 25 are arranged on each of the two sliders 22. The two pulleys 25 on the slider 22 are staggered along a straight line by a certain distance. The pulleys 25 on the two sliders 22 are respectively slidably embedded in the two guide grooves 11. In other embodiments, one pulley 25 can also be arranged on the slider 22, or three or more pulleys 25 can be arranged.

[0033] Elastic pressing parts are arranged on the inner sides of the two sliders 22. The elastic pressing parts on the two sliders 22 are respectively pressed on the two side surfaces 101 of the support seat 10. An elastic pressing force is applied to the side surface 101 of the support seat 10 through the elastic pressing parts, so that a damping force is formed when the sliding seat 20 slides relative to the support seat 10. When writing on the front surface of the panel 40, the panel 40 is kept in a fixed position. When it is necessary to move the panel 40, the user moves the outer frame 30, and the external force applied to the outer frame 30 is greater than the above-mentioned damping force, so that the sliding seat 20 moves relative to the support seat 10, and then the purpose of adjusting the position of the moving panel 40 is achieved. The slider 22 includes an inner wall plate 221 close to the support seat 10 and an outer wall plate 222 located outside the inner wall plate 221. The outer wall plate 222 is arranged at a certain distance from the inner wall plate 221. The elastic pressing part is an arc-shaped convex rib 223 arranged on the inner wall plate 221. The arc-shaped convex rib 223 protrudes from the inner wall plate 221 towards the side surface 101 of the support seat 10, so that the arc top part of the arc-shaped convex rib 223 presses against the side surface 101 of the support seat 10, and an elastic pressing force is applied to the side surface 101 of the support seat 10 through the deformation of the arc-shaped convex rib 223. In addition, by contacting the arc-shaped convex rib 223 with the side surface 101 of the support seat 10, while the slider 22 mutually supports the side surface 101 of the support seat 10 to improve the sliding stability of the sliding seat 20, the contact area between the slider 22 and the support seat 10 is small, reducing the wear of the slider 22. In order to enable the arc-shaped convex rib 223 to have a certain strength, a support rib 224 is also arranged on the slider 22. One end of the support rib 224 is connected to the arc-shaped convex rib 223, and the other end is connected to the outer wall plate 222 of the slider 22.

[0034] In order to enable the entire sliding seat 20 to have better strength, a plurality of reinforcing ribs 24 are arranged at the position where the outer wall plate 222 of the slider 22 is connected to the mounting plate 21. One side of the reinforcing rib 24 is connected to the mounting plate 21, and the other side is connected to the outer wall plate 222 of the slider 22. The plurality of reinforcing ribs 24 are arranged in a straight line.

[0035] The upper frame 31 and the lower frame 32 are connected together by screws. Specifically, a plurality of convex columns 311 extending downward are arranged on the lower surface of the upper frame 31, and a plurality of positioning holes 321 corresponding to the convex columns 311 one by one are arranged on the lower frame 32. The convex columns 311 are inserted into the positioning holes 321. A screw hole is arranged on the convex column 311, and a screw is screwed into the screw hole. The screw penetrates into the positioning hole 321 from bottom to top and is then screwed into the screw hole on the convex column 311, thereby fixedly connecting the lower frame 32 and the upper frame 31 together.

[0036] Finally, it should be noted that the above-mentioned embodiments are only optional embodiment modes of the present invention, and the protection scope of the present invention cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the protection scope required by the present invention.
