Detailed ways

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figure 1. In this embodiment, an easily adjustable multifunctional drawing board includes a drawing board 1. Fixed components 3 are provided at the left and right ends of the drawing board 1. An adjustment component 4 is provided at the end of the fixed component 3 away from the drawing board 1. Two pillars 2 are provided on the adjustment component 4. Support legs 5 are fixed at the bottom ends of the pillars 2. The support legs 5 are triangular support legs. A painting tool rack 6 is fixed between the two support legs 5.

It should be noted that the fixing component 3 can quickly install and disassemble the drawing board 1 of different heights, and the adjusting component 4 can adjust the angle and height of the drawing board 1.

Please refer to Figure 2. In order to facilitate the adjustment of the drawing board 1, the adjustment component 4 in this embodiment includes a movable groove 401 opened inside the pillar 2, and the movable groove 401 is slidably connected to the inside of the movable block 402. The opposite ends of the two movable blocks 402 are rotatably connected to the rotating rod 403, and the outer surface of the rotating rod 403 is threadedly connected to the first nut 404. The front of the movable block 402 is fixed with a screw rod 405. The front of the movable groove 401 is connected to the long groove opened on the pillar 2, and the front of the screw rod 405 passes through the long groove and is slidably connected to it. The outer surface of the screw rod 405 is threadedly connected to the second nut 406, and the back of the second nut 406 is tightly fitted with the front of the pillar 2.

Among them, damping pads are fixed at one end of the first nut 404 and the second nut 406 close to the outer surface of the pillar 2 to improve stability after fixation. The top of the movable groove 401 and the top of the pillar 2 are in the same plane, and the movable block 402 can be moved out along the movable groove 401.

The adjustment component 4 in this embodiment adjusts the rotation angle of the drawing board 1 by rotating the drawing board 1, and then the first nut 404 presses the pillar 2. The movable block 402 slides in the movable groove 401. After the height of the drawing board 1 is adjusted, the pillar 2 can be pressed by the second nut 406.

Please refer to Figure 3. In order to facilitate the fixation of the drawing board 1, the fixing component 3 in this embodiment includes a mounting frame 301 fixed to the opposite end of the two rotating rods 403, and a threaded rod 302 is threadedly connected at the center of the front side of the mounting frame 301. A turntable 303 is fixed to the front side of the threaded rod 302, and a bearing seat 304 is fixed to the back side of the threaded rod 302. A limiting plate 305 is fixed to the back side of the bearing seat 304. A threaded hole is provided on the front side of the mounting frame 301, and the back side of the threaded hole is connected to a hidden groove provided on the mounting frame 301. The limiting plate 305 is slidably connected to the hidden groove, and the hidden groove and the limiting plate 305 are both square, which can prevent the limiting plate 305 from rotating with the threaded rod 302.

The fixing component 3 in this embodiment can quickly fix the drawing board 1 by inserting the drawing board 1 into the movable groove from the top of the mounting frame 301, and then driving the limiting plate 305 to move and press the drawing board 1 through the threaded rod 302.

It can be understood that movable grooves are provided at opposite ends of the two mounting frames 301 , and the left and right ends of the drawing board 1 are slidably connected to the inside of the movable grooves, so as to facilitate the installation of the drawing board 1 .

The working principle of the above embodiment is:

When it is necessary to adjust the angle of the drawing board 1, the drawing board 1 can be rotated to rotate the rotating rod 403. After the angle of the drawing board 1 is adjusted, the first nut 404 can be turned to press the pillar 2 to fix the angle of the drawing board 1. When it is necessary to adjust the height of the drawing board 1, the movable block 402 can slide up and down in the movable groove 401 and drive the screw rod 405 to move up and down. After the height of the drawing board 1 is adjusted, the second nut 406 can be turned to press the pillar 2, and with the cooperation of the damping pad, the stability after adjustment and fixation is improved. When it is necessary to fix the drawing board 1, the drawing board 1 can be slid into the movable groove from the top of the mounting bracket 301, and then the turntable 303 can be turned to drive the threaded rod 302 to rotate. The setting of the direction groove can prevent the limit plate 305 from keeping up with the threaded rod 302 to make a circular motion, and make the limit plate 305 press the drawing board 1, so as to achieve rapid fixation of the drawing board 1.
