The inside of the cavity 2 is located on one side of the rack 3 and is rotatably connected to a gear 6, and the gear 6 is meshed with the rack 3. Either end of the central axis of the gear 6 penetrates the side wall of the cavity 2 It extends to the outside of the support frame 1 and is rotatably connected with a rotary knob 7. Rotating the rotary knob 7 makes the gear 6 slide up and down with the rack 3 inside the cavity 2, so that the angle of the bottom plate 4 can be adjusted. Inside the cavity 2 and located on the other side of the rack 3, a toothed plate 8 is slidably connected by a first spring 9, and the toothed plate 8 is movably engaged with the rack 3, and the front side wall of the support frame 1 is rotatably connected There are two connecting rods 5, the upper ends of the two connecting rods 5 are connected to the lower side wall of the bottom plate 4 in rotation, and the two connecting rods 5 also play the role of supporting the bottom plate 4. When the rack 3 rotates against the bottom plate 4, The angle of the two connecting rods 5 and the bottom plate 4 will also change. When the position of the rack 3 is fixed, the rack 3 and the two connecting rods 5 support the bottom plate 4 together, which can make the bottom plate 4 more stable;

Both sides of the upper end of the bottom plate 4 are slidably connected with a movable plate 10, and the two movable plates 10 are merged together, so that the smaller paper can be painted on the two movable plates 10, and the front and rear ends of the bottom plate 4 can be drawn. There are sliding grooves 12, and the two ends of each sliding groove 12 are slidably connected with the sliding block 11 through the second spring 13. The two movable plates 10 are connected together by the elastic force of the second spring 13 in the natural state. And the upper end of each slider 11 penetrates the side wall of the chute 12 and extends to the outside of the bottom plate 4 and is fixedly connected to the lower side wall of the movable plate 10, and the two sliders 11 on any movable plate 10 are fixed. The pull ropes 23 are connected, and each pull rope 23 bypasses the guide wheel 24 and is fixedly connected to the slider 11 on the same side. The movable plate 10 slides outward, and the two sliders 11 on the lower side of the movable plate 10 in the chute 12 also slide outwards. Pull in the opposite direction, so that the two movable panels 10 can be unfolded together at the same time, the bottom plate 4 is provided with a dark groove 14, and the interior of the dark groove 14 is slidably connected with a lifting plate 16 through a plurality of third springs 15, After the two movable plates 10 are unfolded to the proper position, the lifting plate 16 will be bounced up by the elastic force of the third spring 15, and then the movable plates 10 will be released. 16, so that the lifting plate 16 can be squeezed, so that the two movable plates 10 and the lifting plate 16 form a larger painting surface, which is convenient for placing larger paper for the painter to use.

Specifically, a cam rod 17 is movably connected to the side of the toothed plate 8 away from the rack 3 , and the cam rod 17 is rotatably connected to the interior of the cavity 2 , and one end of the cam rod 17 penetrates the side wall of the cavity 2 It extends to the outside of it, and is slidably connected to the handle 19 through the fourth spring 18. After the angle is adjusted, by pulling the handle 19 and turning it 90 degrees clockwise, the convex point of the cam lever 17 will be against the tooth plate. 8 is fixedly clamped with the rack 3, so that the position of the rack 3 is fixed, so that the angle of the drawing surface is fixed, the inner wall of the handle 19 is provided with a clamping column 20, and the clamping column 20 is connected to the support frame 1. The two card slots 21 on the side walls are movably engaged. When the handle 19 is pulled, the card post 20 can be disengaged from the card slot 21. When the card post 20 is stuck in one of the card slots 21, the cam rod 17 and the toothed plate 8 are not connected. Therefore, the toothed plate 8 cannot fix the position of the toothed rack 3. When the clamping column 20 is stuck in the inside of another clamping slot 21, the convex point of the cam lever 17 is connected with the toothed plate 8, so that the position of the toothed rack 3 is fixed. .

Specifically, storage boxes 22 are provided between the two movable plates 10 and located at both ends of the bottom plate 4, which can store some design tools, such as pencils, rulers, and compasses.

Specifically, the inner side walls of the two movable plates 10 are provided with a plurality of locking blocks 25, and each locking block 25 is movably engaged with the locking holes 26 provided on the side walls of the lifting plates 16. When the lifting plates 16 bounce up When the device is installed, the position of the lifting plate 16 will be fixed after the clamping block 25 is clamped into the interior of the clamping hole 26 on the side wall of the lifting plate 16, thereby ensuring that the lifting plate 16 will not slide downward when the device is deployed and used. Thereby, it is ensured that the two movable plates 10 and the lifting plate 16 can be fixed to maintain a horizontal plane; when the movable plate 10 is stowed, first slide the movable plate 10 away from the guide wheel 24 outward, so that each block 25 and the clamping hole 26 are Disengage from the clamping connection, at the same time, press down the lifting plate 16 to the inside of the dark slot 14, and then release the movable plate 10, the two movable plates 10 will automatically slide inwards, so as to play a role of retraction, the two movable plates The clamping blocks 25 on the 10 are arranged in a cross, and the two movable plates 10 are also provided with corresponding holes, so that the clamping blocks 25 will not interfere when the two movable plates 10 are connected.

Working principle: When using, adjust the size of the painting panel according to the size of the paper used for painting. If the paper is small, put the two movable boards 10 together, so that the smaller paper can be placed on the two movable boards 10. For painting, when the required paper is larger, the movable plate 10 that is far away from the guide wheel 24 is slid outward, and the two sliders 11 on the lower side of the movable plate 10 in the chute 12 also slide outward along with the sliding. At the same time, the two sliders 11 will pull the other movable panel 10 in the opposite direction through the pull rope 23, so that the two movable panels 10 can be unfolded together at the same time. When the movable plate 10 is opened, the two movable plates 10 will slide to the lifting plate 16 by the pulling force of the second spring 13, so that the lifting plate 16 can be squeezed, so that the two movable plates 10 and the lifting plate 16 are combined into a relatively Large drawing surface, so that it is convenient to place larger paper for the painter to use; when the angle of the drawing surface needs to be adjusted, the rotary knob 7 can be turned, so that the gear 6 and the rack 3 slide up and down inside the cavity 2, In this way, the angle of the bottom plate 4 can be adjusted, so as to adjust the angle of the drawing surface. After the angle is adjusted, by pulling the handle 19 and turning it 90 degrees clockwise, the convex point of the cam lever 17 will press against the The toothed plate 8 is fixedly clamped with the rack 3, so that the position of the rack 3 is fixed, so that the angle of the drawing surface is fixed.

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the present invention , alternatives and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
