Technical Field
The utility model relates to an easel especially relates to an easel is used in drawing teaching.
Background
In the existing life, when a teacher teaches art, students are specified in the sitting position inside the teacher, and in the teaching process, a picture needs to be explained from all directions, the picture is fixed on a teaching drawing board, the angle of the picture needs to be changed all the time, and the teaching drawing board is troublesome; on the other hand, in the in-process of fine arts teaching, can let the student draw on the drawing board usually to improve student's drawing ability, the drawing board structure among the prior art is crude, and the drawing board of same type can't satisfy different height student's user demand, and drawing board structure function among the prior art is more single.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem, providing an easel for drawing teaching, it has convenient to use, can take care of the advantage of the classmate of different heights.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an easel for drawing teaching comprises a base and a drawing board, wherein two sliding grooves are formed in the front and back direction of the base, sliding blocks are arranged in the sliding grooves, and a supporting rod with adjustable height is fixed on each sliding block; a fixing plate is fixed between the two support rods, a first through hole is formed in the center of the fixing plate, a bearing is installed in the first through hole, and a nut with threads is installed in the bearing; the drawing board is circular, the second through-hole has been seted up at the center of drawing board, be provided with in the second through-hole with the screw thread matched with bolt of nut, drawing board detachable fixes on the fixed plate.
Furthermore, the middle position of the supporting rod is rotatably fixed with a palette through a palette fixing device.
Further, still be provided with the baffle on the slider, prevent that drawing board from removing at drawing in-process.
Furthermore, dustproof cloth is arranged on the periphery of the drawing board, the dustproof cloth is formed into a cylindrical cloth bag, the diameter of the cloth bag is slightly larger than that of the drawing board, and the length of the cloth bag is slightly larger than the radius of the drawing board; one end of the cloth bag is fixed on the drawing board, the other end of the cloth bag is provided with a contraction rope, and the contraction rope contracts one end of the cloth bag, so that the drawing board which is not used is prevented from being stained with dust.
Furthermore, the lower extreme of base equidistance is provided with the non slipping spur, prevents that the base from removing at the in-process of drawing the picture.
Further, palette fixing device's one end is the clamp, fixes on the bracing piece.
The utility model has the advantages that: the utility model discloses can adapt to the classmate of different heights and draw a picture, the palette is rotatable to be fixed on the bracing piece simultaneously, and convenient mixing of colors is used, and the drawing board can rotate, can rotate at will during each direction analysis is drawn with meeting more convenient.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings and examples.
As shown in fig. 1 to 3, an easel for drawing teaching comprises a base 1 and a drawing board 5, wherein two sliding grooves are formed in the front and back direction of the base 1, sliding blocks are arranged in the sliding grooves, and a supporting rod 2 with adjustable height is fixed on each sliding block; a fixing plate 3 is fixed between the two support rods 2, a first through hole is formed in the center of the fixing plate 3, a bearing 4 is installed in the first through hole, and a nut with threads is installed in the bearing; the drawing board 5 is circular, a second through hole is formed in the center of the drawing board 5, a bolt 9 matched with the screw thread of the nut is arranged in the second through hole, and the drawing board 5 is detachably fixed on the fixing plate 3; a palette fixing device 8 is rotatably fixed at the middle position of the support rod 2, a palette 7 is fixed at one end of the palette fixing device 8, a clamp is arranged at the other end of the palette fixing device, and the palette fixing device 7 is fixed on the support rod 2 by the clamp; still be provided with the baffle on the slider, prevent that drawing board removes at drawing in-process. The periphery of the drawing board 5 is provided with dustproof cloth 10, the dustproof cloth 10 is formed into a cylindrical cloth bag, the diameter of the cloth bag is slightly larger than that of the drawing board, and the length of the cloth bag is slightly larger than the radius of the drawing board; one end of the cloth bag is fixed on the drawing board 5, the other end of the cloth bag is provided with a contraction rope 11, the contraction rope 11 contracts one end of the cloth bag, the drawing board 5 which is not used is prevented from being stained with dust, and the antiskid blocks 6 are arranged at the lower end of the base 1 at equal intervals, so that the base is prevented from moving in the drawing process.
Use the utility model discloses the time, remove the bracing piece 2 to the suitable position of base through the slider, then use the baffle fixed, with 7 rotatory all suitable positions in palette, then with drawing board 5 through bolt 9 and nut fixed connection together, open the sack that hides the ash, fix the drawing and just can explain the drawing on drawing board 5, when needs are rotatory, bearing 4 can drive drawing board 5 rotatory. When the picture is drawn, the height of the supporting rod 2 can be adjusted to be suitable for drawing.
Although the present invention has been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without inventive work are still within the scope of the present invention.
