Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which are derived by a person skilled in the art based on the embodiments of the utility model, fall within the scope of protection of the utility model.
Embodiments of the utility model:
as shown in fig. 1-7, a portable liftable art drawing board comprises a drawing board body 1 and supporting legs, wherein the drawing board body 1 comprises a panel 12 and a frame 11, the frame 11 is a rectangular frame 11, and the panel 12 is embedded in the frame 11. The panel 12 includes an iron plate for attracting the magnet, and the magnet sheet can be used to press the drawing paper to fix the drawing paper on the front side of the panel 12. The front side of the iron plate is provided with a surface layer, which is common in the prior art, and the chalk scratch can be attached by adopting a green coating. Of course, a white surface layer can be used alternatively for painting with a whiteboard pen.
The two legs are symmetrically arranged at the two sides of the frame 11. Two bolt holes 14 are respectively arranged on two side edges of the frame 11, the supporting leg comprises a first rod 2 and a second rod 3, a T-shaped groove 23 is formed in the first rod 2, the opening of the T-shaped groove faces one side of the drawing board frame 11, the length direction of the T-shaped groove is arranged along the length direction of the supporting leg, and the T-shaped groove is used for installing the bolt 6. The threaded section of the bolt passes through and protrudes out of the bolt hole 14, and the protruding end of the bolt is in threaded connection with the nut 5.
As shown in fig. 7, the bolt 6 includes a polish rod section 61 and a screw section 63, and a rotation stop section 62 of a hexagonal prism or a quadrangular prism is provided on the polish rod section 61. As shown in fig. 4 to 6, the T-shaped groove is formed of a first groove 231 and a second groove 232 which are communicated with each other, the first groove 231 has a larger width than the second groove 232, the rotation stopping section 62 is positioned in the first groove 231, the polish rod section 61 is positioned in the second groove 232, and the screw thread section 63 passes through the second groove 232 and extends out of the second groove 232. The first rod 2 is located on the front side of the frame 11, and the first rod 2 is movable relative to the frame 11 after unscrewing the nut 5. The nut 5 is a butterfly nut or a plum blossom nut, which is convenient to operate.
The T-shaped groove is provided at one end portion thereof with a fitting opening 233 having a diameter corresponding to the width of the first groove 231 for fitting the rotation stop section of the bolt, because the width of the second groove 232 of the T-shaped groove is smaller than the outer diameter of the rotation stop section 62.
