Referring to fig. 1, in the present application, the annular crash-proof member 2 is made of a highly elastic polymer material.

The working principle of the utility model is as follows:

referring to fig. 1-5, when the drawing board body 1 is used, the annular anti-falling piece 2 wraps the frame of the drawing board body 1, when the drawing board body 1 falls to the ground, the annular anti-falling piece 2 is contacted with the ground for the first time, the annular anti-falling piece 2 is elastic, can generate larger deformation under the action of small external force, the reaction force applied to the drawing board body 1 by the ground is counteracted through elastic deformation, so that the drawing board body 1 is in soft contact with the ground through the annular anti-falling piece 2 at the moment of falling, the damage probability of the drawing board body 1 is reduced, the anti-falling performance of the drawing board body 1 is improved, meanwhile, if the height of the desktop is not enough in the using process of the drawing board body 1, the supporting mechanism 4 can be taken out from the soft accommodating sleeve 3, and then the supporting mechanism 4 is in threaded connection with the threaded column 6 through the threaded groove 5, fixing the supporting mechanism 4 on the back of the drawing board body 1, then expanding the supporting legs 10 in multiple directions through the hinged relation of the supporting legs 10 and the first support 11, in the process of expanding the supporting legs 10, enabling the pull rope 9 which is originally in a loose state to be in a tight state after the supporting legs 10 rotate in place, and limiting the supporting legs 10, at the moment, the drawing board body 1 can directly contact with a desktop through the four supporting legs 10, so that the drawing board body 1 can be stably supported, meanwhile, the height of the drawing board body 1 is directly increased through the sleeve 8 and the mounting rod 16 on the supporting mechanism 4, if the height is insufficient, the butterfly bolt 19 can be manually rotated, the butterfly bolt 19 is screwed out of the inner part of the corresponding positioning groove 23, at the moment, the butterfly bolt 19 does not limit the position of the central shaft 7, and the central shaft 7 and the sleeve 8 can be relatively slid, the middle shaft 7 is pulled out towards the outside of the sleeve 8, the height of the drawing board body 1 can be lifted through the matching with the mounting rod 16, when the height is proper, the butterfly bolt 19 can be rotated to be screwed into the corresponding positioning groove 23, so that the drawing board body 1 is fixed on the designated height, the drawing board body 1 can be changed in height under the clamping of the supporting mechanism 4, meanwhile, the supporting mechanism 4 and the drawing board body 1 are in a vertical relation before the structure on the supporting mechanism 4 is not unfolded, the supporting mechanism 4 can be directly used as a supporting frame, the drawing board body 1 can be obliquely placed, if the supporting mechanism 4 is not needed to be used, the drawing board body is integrally placed into the soft receiving sleeve 3 for receiving, excessive space is not occupied through the retractility of the supporting mechanism 4 and the receiving of the soft receiving sleeve 3 to the supporting mechanism 4, and the drawing board can be used at any time, the drawing board body 1 is more convenient and flexible to use.

Referring to fig. 2 and 4, in use, after the height of the drawing board body 1 is changed by the supporting mechanism 4, if the drawing board body 1 is supported by only one supporting point of the mounting rod 16, the stability of the drawing board body 1 is not good, therefore, when the supporting mechanism 4 is used, the four movable rods 15 can be unfolded in multiple directions by the hinged relationship of the second support 12, the angle between the limiting arm 14 and the movable rods 15 can be increased in the unfolding process of the movable rods 15, the sliding block 26 can be driven to slide on the slide way 24, finally the sliding block 26 is moved in place, the movable rods 15 are limited by the limiting arm 14, at this time, the unfolding angle of the movable rods 15 is also in place, then the rubber cushion block 18 is rotated, the rotation of the rubber cushion block 18 drives the threaded rod 17 to rotate, and the rubber cushion block 18 is moved to the back of the drawing board body 1 by the threaded transmission of the threaded rod 17 and the adjusting groove 25, finally, the back of rubber cushion block 18 and drawing board body 1 contacts, also makes the back of drawing board body 1 have had four more strong points, has alleviated through the pressure that 16 single-points of erection pole supported, increases drawing board body 1's stability, makes child can be relieved and draw a picture, and soft contact through rubber cushion block 18 and drawing board body 1 has avoided drawing board body 1 to produce unnecessary contact wear simultaneously, has improved its practicality.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the utility model can be made, and equivalents and modifications of some features of the utility model can be made without departing from the spirit and scope of the utility model.
