Technical field

The utility model is related to a kind of teaching auxiliary tools, and in particular to a kind of drawing shelf.

Background technology

At present, art major includes oil painting, calligraphy, the directions such as traditional Chinese Painting, sketch, and each required material in direction is different , required support shelf difference is very big when especially operating, and oil painting needs that the high big rack of steady picture frame, shelf can be held in the palm Allow there is certain adjusting space to adapt to the variation of picture frame size；Calligraphy, traditional Chinese Painting class need bigger horizontal table top ability Complete operation；Need drawing board that can make the inclination of certain angle during sketch, drawing board area change is limited.Such requirement, at present The shelf for completing these study requirements of drawing a picture there are no a kind of shelf can be provided, be largely the work for only supporting one or two kind of function Draw the shelf of requirement.

The content of the invention

The technical problem to be solved by the utility model is to provide a kind of drawing shelfs, can be made up of not simple operations Similar shape structure provides and ensures that difference draws a picture, writes the support needed, realizes and meets all art major study, the institute of creation It needs.

The utility model technical scheme applied to solve the technical problem is：A kind of drawing shelf, including pedestal and two Braced frame, the pedestal are equipped with rotatable two pairs of gears；Described two braced frames are connected on two pairs of gears, Panel is respectively equipped in described two braced frames, the panel is flexibly connected by crossbeam with braced frame, described two Pressure pin is further respectively had on support frame frame.

As a further improvement, the horizontal grid among the pedestal are equipped with four-bar jack, and the four-bar is very heavy Top top is equipped with extended segment, and pressure pin is withstood in extended segment when the four-bar jack is upward.

As a further improvement, threaded rod is equipped between the four-bar jack, hand is equipped among the threaded rod Wheel.

As a preferred embodiment, it is detachable connection between the braced frame and gear.

As a further improvement, a pair of matched hinge is respectively equipped at the top of described two braced frames.

As a preferred embodiment, the magnet to attract each other is respectively equipped in the pressure pin and braced frame, to realize pressure pin It slides.

As a preferred embodiment, the crossbeam is cylinder.

The utility model adjusts braced frame angle by gear rotation, is needed to adapt to various art teaching situations It asks, it is simple and convenient.

The beneficial effects of the utility model are:Its is simple in structure, can form different shape structure by simple operations, carry For ensureing that difference draws a picture, write the supports needed, realize meet the study of all art majors, create it is required.

The utility model is described further below in conjunction with the accompanying drawings.

Specific embodiment

Embodiment 1：As shown in Figure 1, a kind of drawing shelf, including pedestal 1 and two braced frames 3, the pedestal 1 One is equipped with rotatable two pairs of gears 2, and described two braced frames 5 are connected to by bolt on two pairs of gears 2 respectively, and described two Panel 4 is respectively equipped in a braced frame 3, the panel 4 is described two by cylindrical beam 5 and the dynamic connection of braced frame 3 Pressure pin 6 is also set in braced frame 3 respectively, the pressure pin 6 in braced frame 3 with being respectively equipped with the magnet to attract each other, to realize The slip of pressure pin 6.Described two 5 tops of braced frame are respectively equipped with a pair of matched hinge 7.Horizontal stroke among the pedestal 1 Grid 8 are equipped with four-bar jack 9, and 9 top of the four-bar jack is equipped with extended segment 12, the four-bar jack 9 to Pressure pin 6 is withstood in extended segment 12 when upper, and threaded rod 10 is equipped between the four-bar jack 9, is equipped among the threaded rod 10 Handwheel 11.

When actual use is suitble to general drawing, braced frame 3 is perpendicular in pedestal state at this time, and hinge 7 and gear 2 are divided Not Gu Ding, move up and down pressure pin 6, the panel 4 of suspension and braced frame 3 formed into different angle, panel 4 is made to reach suitable drawing Angle of inclination, drawing paper is layered on panel 4 and can paint, can also control two people at this time and paint simultaneously.

In addition, small-sized oil painting can also be carried out in the case where easel is in general drawing state, as long as being at this moment placed on panel 4 Pressure pin 6 is below and in braced frame 3, and oil painting frame is placed on pressure pin 6, then fixing oil picture frame upper end.

Embodiment 2：As shown in Figure 2, in actual use, it is suitble to calligraphy, traditional Chinese Painting practice, the axis pin of hinge 7 is taken out, together When also gear 2 and the bolt of pedestal 1 are taken out, two braced frames 3 respectively around 2 axle center of gear be flared out to setting position It puts, then bolt is plugged with fixing support rack frame 3, the 4 steering horizontal position of panel hung in braced frame 3, and will left and right two The docking of panel 4 is fixed, and a horizontal desk, which builds completions, calligraphy, traditional Chinese Painting etc., at this time needs the horizontal drawing exercises operated can be with It completes herein.Other embodiments 1 are identical.

Embodiment 3：As shown in Figure 3, in actual use, it is suitble to Oil Painting, by the lower end of one side braced frame 3 and tooth 2 separation of wheel, then this braced frame 3 is flipped up around the axis pin of hinge 7, become same vertical flat with opposite side braced frame 3 On face, and it is fixed, and upper and lower surfaces plate 4 is both placed in the one side of braced frame 3；The pressure pin 6 of upper lower support frame 3 is used as oil painting The fixing device of frame, since oil painting frame gravity is heavier under vertical state, so when be finely adjusted and hold using four-bar jack 9 Again, handwheel 11 is rotated during adjusting to adjust required position, has oil painting frame by the space of pressure pin 6 It tilts, and places secured.It is usually that a people draws a picture at this time.It is other same as Example 1.
