Mechanical drawing is the required professional basic course of each Techniques for Machinery Students, although engineers all uses computer graphics in present factory, but Freehandhand-drawing machinery drawing is the technical ability that each Engineering Students must be grasped, and one of several basic tools that mechanical drawing will use are exactly drawing board.
The drawing board of mechanical drawing class is divided into A0, A1, A2, A3, A4 five kinds of sizes, be mostly wooden, but existing drawing board all need with easel with the use of, and cannot the height of free adjustment drawing board, often kind of drawing board is of a size of fixing, cannot adapt to the demand that drawing is changeable.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of lifting mechanical drawing drawing board, by designing height adjustable folding drawing board, to solve the defect that existing drawing board cannot regulate height and size to fix.
For achieving the above object, the utility model provides following technical scheme: a kind of lifting mechanical drawing drawing board, it is characterized in that: described lifting mechanical drawing drawing board comprises a pancake base, base center is provided with a support column vertical with base, base and support column are monolithic construction, support column offers one and attack threaded hole, threaded rod is provided with in hole, threaded rod and support column threaded engagement, the installing plate of circular plate type is provided with above threaded rod, threaded rod and installing plate are monolithic construction, the heart portion drawing board of rectangle is fixed with above installing plate, heart portion drawing board skin overlaps the middle level drawing board and outer drawing board that have in " returning " font successively, heart portion drawing board, middle level drawing board, outer drawing board long limit correspondence position is provided with two through hole, fixed bar is equipped with in two through hole, fixed bar handle diameters is greater than through-hole diameter, and fixed bar shaft has attacked convex thread, the fixed bar other end fixes heart portion drawing board by hold-down nut, middle level drawing board, outer drawing board.
Preferably, described base, support column, threaded rod, installing plate are by carbon structure steel making, and top layer is all brushed with antirust paint.
Preferably, described heart portion drawing board, middle level drawing board, outer drawing board are by timber manufacture.
Preferably, described heart portion drawing board and middle level drawing board and middle level drawing board and outer drawing board are interference fits.
Preferably, described heart portion drawing board is fixed on installing plate upper surface by 4-6 root screw.
Preferably, the length of described two fixed bars is all greater than the width of outer drawing board.
The beneficial effect of above technical scheme is adopted to be: the base center of this lifting mechanical drawing drawing board is provided with a support column vertical with base, threaded rod and support column threaded engagement, the installing plate of circular plate type is provided with above threaded rod, the heart portion drawing board of rectangle is fixed with above installing plate, heart portion drawing board skin overlaps the middle level drawing board and outer drawing board that have in " returning " font successively, heart portion drawing board, middle level drawing board, outer drawing board long limit correspondence position is provided with through hole, fixed bar is provided with in through hole, the fixed bar other end fixes heart portion drawing board by hold-down nut, middle level drawing board, outer drawing board, this drawing board is elevated the height of drawing board by rotating threaded rod, facilitate handy, and by fixed disassembly bar, installation or removal middle level drawing board and outer drawing board, arbitrarily can adjust the size of drawing board, the convenient machine drawing drawing different size.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Fig. 1 is the front view of a kind of lifting mechanical drawing of the utility model drawing board;
Fig. 2 is the top view of a kind of lifting mechanical drawing of the utility model drawing board.
Wherein, 1-base, 2--support column, 3-threaded rod, 4-installing plate, 5-heart portion drawing board, 6-middle level drawing board, 7-outer drawing board, 8-fixed bar, 9-hold-down nut, 10-screw.
Detailed description of the invention
The preferred embodiment of a kind of lifting mechanical drawing of the utility model drawing board is described in detail below in conjunction with accompanying drawing.
Fig. 1 and Fig. 2 shows the detailed description of the invention of a kind of lifting mechanical of the utility model drawing drawing board: this lifting mechanical drawing drawing board comprises a pancake base 1, base 1 center is provided with a support column 2 vertical with base 1, base 1 and support column 2 are monolithic construction, support column 2 offers one and attack threaded hole, threaded rod 3 is provided with in hole, threaded rod 3 and support column 2 threaded engagement, the installing plate 4 of circular plate type is provided with above threaded rod 3, threaded rod 3 and installing plate 4 are monolithic construction, the heart portion drawing board 5 of rectangle is fixed with above installing plate 4, heart portion drawing board 5 skin overlaps the middle level drawing board 6 and outer drawing board 7 that have in " returning " font successively, heart portion drawing board 5, middle level drawing board 6, outer drawing board 7 long limit correspondence position is provided with two through hole, fixed bar 8 is equipped with in two through hole, fixed bar 8 handle diameters is greater than through-hole diameter, and fixed bar 8 shaft has attacked convex thread, fixed bar 8 other end fixes heart portion drawing board 5 by hold-down nut 9, middle level drawing board 6, outer drawing board 7.
