DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] like Figures 1 to 5 As shown, a detachable drawing board stand structure includes a drawing board stand and a plurality of drawing board bodies 3;

[0023] The drawing board frame has a supporting bottom plate 21, a side frame 22 and a top frame 23. The side frame 22 is fixed on the supporting bottom plate 21, and the side frame 22 is fixed to the top frame 23. A partition board 24 is fixed between the two side frames 22. The inner side of the side frame 22 has a first step frame 4. The interior of the first step frame 4 is hollow. A plurality of first limiting holes 41 are opened on the first step frame 4 from top to bottom. Second limiting holes 42 are arranged on the top frame 23 and the partition board 24. A plurality of first limiting blocks 31 are symmetrically arranged on one side of the drawing board body 3. The first limiting block 31 has a first limiting portion 32. The first limiting portion The block 31 passes through the first limiting hole 41 of the first step frame 4 and presses the first limiting part 32 against the inner side wall of the first step frame 4; the partition plate 24 and the bottom of the top frame 23 have a second step frame 5, and a second limiting block 33 is also arranged on the top of one side of the drawing board body 3, and the second limiting block 33 has a second limiting part 34, and the second limiting block 33 passes through the second limiting hole 42 and presses the second limiting part 34 against the inner side wall of the first step frame 4; a snap-in groove 241 is also provided on the partition plate 24, and a snap-in block 242 is provided at the bottom of the drawing board body 3, and the snap-in block 242 is snap-in engaged with the snap-in groove 241.

[0024] With the above structure, a number of drawing board bodies 3 are provided which are detachably and buckled to be fixed on the drawing board stand. During the installation process, the first limiting parts 32 symmetrically provided on the drawing board body 3 match the first limiting holes 41 provided on the first step frame 4, and the second limiting parts 34 symmetrically provided on the drawing board body 3 match the second limiting holes 42. When the drawing board body 3 is placed on the drawing board stand, the first limiting parts 32 pass through the first limiting holes 41, and the second limiting parts 34 pass through the second limiting holes 42. The height of the drawing board body 3 including its clamping block 242 is exactly the same as the distance between the bottom of the top frame 23 and the top of the partition board 24. When the drawing board body 3 is placed on the first step frame 4 on the drawing board stand, After the frame 4 is pushed in and abutted, the drawing board body 3 can move downward again, and the first limiting portion 32 passes through the first limiting hole 41 and moves downward and snaps into the inner wall of the first step frame 4. The second limiting portion 34 passes through the second limiting hole 42 and moves downward and snaps into the inner wall of the second step frame 5, which is conducive to a stable installation structure and quick installation, which is more convenient. At the same time, the snap-in block 242 at the bottom of the drawing board body 3 is limited downward and snaps into the snap-in groove 241, which is conducive to firm fixation, splicing the drawing board body 3 and the drawing board frame into one, thereby improving the overall strength. If it needs to be disassembled, the drawing board body 3 can be lifted up and moved, so that the drawing board body 3 can be quickly taken out, which is convenient and quick.

[0025] Specifically, if Figures 1 to 5 As shown, the first step frame 4 has a first contact surface 43, and the distance b between one side surface of the side frame 22 and the first contact surface 43 of the first step frame 4 is equal to the thickness c of the drawing board body 3. The partition board 24 and the bottom of the top plate have a second step frame 5, and the distance b between one side surface of the side frame 22 and the first step frame 4 is equal to the thickness c of the drawing board body 3.

[0026] Through the above structure, the distance b from one side of the side frame 22 to the first step frame 4 is equal to the thickness c of the drawing board body 3, which ensures that the drawing board body 3 can be flush with the side frames 22 on both sides of the drawing board frame after being placed in the drawing board frame, and the drawing board body 3 does not protrude abruptly, thereby improving the aesthetics and integrity of the device.

[0027] like Figures 1 to 5 As shown, guide plates 61 are provided on both sides of the step frame near the first limiting hole 41 to guide the first limiting block 31. The provision of the guide plates 61 helps ensure that the first limiting block 31 moves linearly when passing through the first limiting hole 41 without deviation, making installation more precise and convenient.

[0028] like Figures 1 to 5 As shown, a plurality of reinforcing rods 7 are also installed between the two side frames 22. By providing the reinforcing rods 7, the structure and strength of the device are strengthened.

[0029] like Figures 1 to 5 As shown, cushioning pads 62 are installed at the four corners of the common surface between the drawing board body 3 and the first limit block 31 and the second limit block 33. The cushioning pads 62 reduce the impact force generated when the drawing board body 3 is placed in the drawing board stand, thereby protecting the drawing board body 3 and the drawing board stand, and achieving better protection.

[0030] like Figures 1 to 5 As shown, the bottom of the support base plate 21 of the drawing board stand is equipped with a plurality of universal wheels 63. By providing the universal wheels 63, it is convenient to move the drawing board stand and the mounted drawing board body 3, which is highly practical.
