Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, a portable drawing board comprises a pair of parallel frame plates 1, a fixed plate 2 is integrally arranged between the frame plates 1, the fixed plate 2 is positioned on one side of the width direction of the frame plates 1, the frame plates 1 and the fixed plate 2 are vertically arranged, a movable plate 3 is further arranged between the frame plates 1, the movable plate 3 is parallel to the fixed plate 2, supporting springs 4 are respectively arranged at four corners between the movable plate 3 and the fixed plate 2, and a limiting component is arranged on one side of the frame plates 1 away from the fixed plate 2 and used for limiting the moving range of the movable plate 3;
when carrying the drawing paper, all put into between the frame board 1 with the drawing paper, supporting spring 4 promotes fly leaf 3, and fly leaf 3 extrudees the drawing paper and extrudees with spacing subassembly to realize the fixed of drawing paper, when needs change the drawing paper, take out the drawing paper of the top can, thereby make things convenient for drawing and carrying.
Wherein, a limiting column 5 extends from the four corners of the opposite side of the movable plate 3 and the fixed plate 2, and the two ends of the supporting spring 4 are sleeved on the limiting column 5, so as to ensure the fixing of the supporting spring 4 between the movable plate 3 and the fixed plate 2. Meanwhile, the movable plate 3 extends towards two ends of the side frame plate 1 to form a limiting part 31, the limiting part 31 penetrates through the side frame plate 1, an avoiding groove 11 for the limiting part 31 to move is reserved on the side frame plate 1, and the limiting part 31 is matched with the avoiding groove 11, so that the moving direction of the movable plate 3 is ensured, and the movement of stably pushing the drawing paper is realized.
One end of the limiting part 31 penetrating through the frame plate 1 is provided with a mounting groove, a cam 32 is hinged in the mounting groove, the hinge axis of the cam 32 is parallel to the frame plate 1, an extending plate is fixed on the cam 32, the cam 32 can be easily operated to rotate through the extending plate, the cam 32 comprises a convex part 321 and a concave part 323, and a rubber layer 322 is attached to the convex part 321;
because during drawing, the movable plate 3 needs to bear certain pressure and keep still, so drive the cam 32 to rotate to the bulge 321 and extrude with the frame plate 1 through the extension plate, the static friction between the cam 32 and the frame plate 1 is enough to offset the pressure that receives during drawing, and the setting of the rubber layer 322 has further increased the maximum static friction between the cam 32 and the frame plate 1, thereby the stability of the drawing board during drawing has been guaranteed.
Spacing subassembly includes a pair of parallel slide rail 6, and slide rail 6 is fixed in the one side of carrying on the back mutually between the frame board 1 respectively, and slide rail 6 extends along the length direction of frame board 1, and the cooperation has gliding slider 7 on slide rail 6, and it has straight baffle 71 to extend on the slider 7, and the one end of baffle 71 extends between the frame board 1 to can block the removal of drawing paper and fly leaf 3. Meanwhile, the sliding block 7 is in threaded connection with a bolt 8, and the bolt 8 penetrates through the sliding block 7 and can be in extrusion fit with the sliding rail 6, so that the sliding block 7 and the baffle 71 are limited to move, and the fixing of drawing paper during drawing is guaranteed.
And when a large amount of drawing paper needs to be installed in the frame, the rotating bolt 8 is separated from the sliding rail 6, and then the sliding block 7 is taken down, namely the baffle 71 is separated from the space between the frame plates 1, so that the drawing paper is conveniently installed in the drawing board.
The implementation principle of the embodiment is as follows:
the drawing paper is arranged between the frame plates 1 of the drawing board, so that the drawing paper is convenient to carry; when the drawing paper needs to be replaced, the cam 32 is loosened, the drawing paper on the uppermost layer is drawn out, the movable plate 3 is driven by the supporting spring 4 to push the drawing paper on one side to be extruded with the baffle 71, and the cam 32 is rotated to be extruded with the frame plate 1, so that the movable plate 3 and the drawing paper are fixed, and the purpose of rapidly replacing the drawing paper is achieved.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
