Detailed ways

The present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

The utility model provides a public drawing rack for a library, which includes a fixed steel frame 1 and a lifting mechanism 9 as shown in FIG. 2 and 3, the lifting mechanism 9 includes racks 15 which are respectively arranged opposite to each other on both sides of the fixed steel frame 1, and also includes a drawing board 3. The top ends of the drawing board 3 are provided with gears 13 that cooperate with the racks 15, and the gears 13 are connected. The damping motor 16 is connected with a lift switch and an external power supply. The user adjusts the angle of the drawing board 3 by controlling the lift switch and the damping motor 16. The rack 15 is also sleeved with a rack fixing sliding sleeve 14, the rack One side of the fixed sliding sleeve 14 is arranged around the gear 13, one end of the fixed sliding sleeve 14 is connected with the top of the drawing board 3 through the rotating shaft 12, and a rotating shaft sleeve 10 is also sleeved between the rotating shaft 12 and the drawing board 3, and the fixed sliding sleeve 14 is also provided with There is a motor fixing frame 17 matched with the damping motor 16. The bottom ends of the drawing board 3 are respectively connected to the fixed steel frame 1 through the supporting frame 7. The damping motor 16 drives the gear 13 to rotate, and the gear 13 slides on the rack 15, thereby driving the rack. The fixed sliding sleeve 14 slides up and down along the rack 15, and because the other end of the drawing board 3 is provided with a support frame 7, the other end of the support frame 7 is arranged on the fixed steel frame 1, and the two ends of the support frame 7 are respectively connected with the fixed shaft 6. The drawing board 3 is connected with the fixed steel frame 1, so the drawing board 3 will change the inclination angle due to the lifting and lowering of the lifting mechanism 9 for the user to use;

One end of the fixed steel frame 1 close to the top of the drawing board 3 is also provided with a ceiling light 2, the surface of the drawing board 3 is also provided with several light strips 11 in parallel, the surface of the drawing board 3 is located on the upper part of the light strip 11 and a translucent acrylic plate 4 is also laid, and the bottom of the drawing board 3 is also A baffle 5 is provided, and a storage box 8 is also provided on one side of the surface of the drawing board 3 .

As shown in FIG. 4 , when the light of the easel is insufficient for the user, the upper end of the fixed steel frame 1 is provided with a ceiling light 2, which can be turned on according to the user’s needs. Through the translucent acrylic plate 4 arranged on the drawing board 3, all the lights are set to be adjustable in brightness, the lower side of the drawing board 3 is provided with a baffle 5, which is used to fix the paper and wood, and the right side of the drawing board 3 is also provided with The storage box 8 is used to place the required painting tools;

As shown in FIG. 5 , when the easel is not in use, the user can control the lift switch to start the lift mechanism 9, and the drawing board 3 is lifted up and stored, returning to the initial state.
