[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0019] See Figure 1-4 , The present invention provides a technical solution: a drawing board for environmental art design, comprising a base 1, a first box 2 is fixedly connected to the left side of the top of the base 1, and a support is provided through the right side of the top of the first box 2 Column 3, the top and bottom of the inner cavity of the first box 2 are provided with a first sliding groove 4, the inner cavity of the first sliding groove 4 is slidably connected with a first sliding block 5, the first sliding block 5 and the first sliding groove 4 The opposite sides of the two first sliders 5 are fixedly connected with a connecting block 6, the right side of the connecting block 6 is fixedly connected with a clamping block 7, and the left side of the support column 3 is provided with a clamping block 7 In the card slot 8, the right side of the card block 7 extends to the inner cavity of the card slot 8. The inner cavity of the connecting block 6 is movably connected with a movable rod 9 through a rotating shaft. The number of movable rods 9 is two, and the left side of the movable rod 9 The second sliding block 10 is movably connected through the rotating shaft. The top and bottom of the left side of the inner cavity of the first box body 2 are both provided with a second sliding groove 11 that is adapted to the second sliding block 10. The side is slidably connected to the first box body 2, one side of the second slider 10 is fixedly connected with a spring 12, the side of the spring 12 away from the second slider 10 is fixedly connected to the first box body 2, and the left side of the connecting block 6 A pull rod 13 is fixedly connected, the pull rod 13 is located on the rear side of the movable rod 9, the left side of the pull rod 13 penetrates to the left side of the first box 2 and is fixedly connected with a pull block 14, and the front side of the support column 3 is fixedly connected with a second Box 15, the left side of the second box 15 is provided with a threaded rod 16 therethrough, the surface of the threaded rod 16 is threadedly connected with a threaded sleeve 17, the right end of the threaded rod 16 is fixedly connected to the limit block 18, and the left side of the threaded rod 16 is fixed A handle 19 is connected. The top of the threaded sleeve 17 is movably connected with a support rod 20 through a shaft. The top of the support column 3 is movably connected with a drawing board 21 through a shaft. The top of the support rod 20 is movably connected with the drawing board 21 through a shaft. The second box The top of the body 15 is provided with a movable groove 22 adapted to the support rod 20.

[0020] In the present invention, the top and bottom of the limiting block 18 are fixedly connected with pulleys 23, the inner cavity of the second box 15 is provided with pulley grooves that are adapted to the pulleys 23, and the shape of the second box 15 is cylindrical, Through the arrangement of the pulley 23, the threaded rod 16 can have a fixed rotation track, which prevents the threaded sleeve 17 from falling off, and improves the stability of rotation.

[0021] In the present invention: the bottom of the base 1 is fixedly connected with an anti-skid pad, and the thickness of the anti-skid pad is not less than six millimeters. By setting the anti-skid pad, the base 1 can be in good contact with the ground, avoiding the problem of shaking of the base 1, and improving The stability of the base 1 is improved.

[0022] In the present invention, a through hole adapted to the threaded rod 16 is opened on the left side of the second box 15, and a through hole adapted to the pull rod 13 is opened on the left side of the support column 3.

[0023] In the present invention: the rear side of the drawing board 21 is fixedly connected with a shelf 24, and the inner cavity of the shelf 24 is provided with a placing slot. The arrangement of the shelf 24 can enable the user's drawing tools to be placed, avoiding the user back and forth The condition of taking drawing tools improves the drawing efficiency of users.

[0024] Working principle: When the present invention is used, the user pulls the pull block 14 to drive the pull rod 13 and the movable rod 9 to move, the movable rod 9 drives the second slider 10 to move the compression spring 12, and then the pull rod 13 drives the connecting block 6 and the clamping block 7 to move Move to the left, and then insert the support column 3 into the first box 2, then loosen the pull block 14, the spring 12 drives the movable rod 9 to move toward each other, the movable rod 9 drives the connecting block 6 to move to the right, and the connecting block 6 drives the clamping block 7. Move to the right to achieve a stable effect. Shaking the handle 19 drives the threaded rod 16 to rotate, and the threaded rod 16 drives the threaded sleeve 17 to move left and right. The threaded sleeve 17 adjusts the angle of the drawing board 21 through the support rod 20 to achieve an adjustable angle. The purpose of improving user efficiency.

[0025] To sum up: the drawing board for design of the ring art, through the connecting block 6, the clamping block 7, the clamping groove 8, the movable rod 9, the spring 12, the pull rod 13, the pull block 14, the second box 15, the threaded rod 16, The coordinated use of the threaded sleeve 17, the handle 19, the support rod 20 and the drawing board 21 solves the problems of poor fixing effect and unadjustable angle of the traditional drawing board.
