Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
See Fig. 1-Fig. 5, this utility model relates to a kind of adjustable drawing board bracket, including base 1, drawing board lowering or hoisting gear, drawing board bracket, drawing board angular adjustment apparatus 4, described drawing board lowering or hoisting gear is fixed on base 1, and drawing board bracket is linked together by drawing board angular adjustment apparatus 4 and drawing board lowering or hoisting gear.
Described drawing board lowering or hoisting gear is foot-operated 23 by cylinder 21, piston 22, lifting, lifting lead 28, connect seat 24, cylinder controls mandrel 25, pressing plate 26 and connecting rod 27 and forms, wherein cylinder 21 is fixed on base 1；Piston 22 is hollow structure, and lower end is inserted in cylinder 21, connection is fixed with being connected seat 24 in upper end；Cylinder controls mandrel 25 and is arranged in piston 22；Pressing plate 26 is close to cylinder control mandrel 25 and is provided above, one end is with to be connected seat 24 inwall hinged, it is hinged with lifting lead 28 that one end passes connection seat 24, lifting lead 28 other end is connected with lifting foot-operated 23, lifting foot-operated 23 is fixed on base 1, foot is stepped on lifting foot-operated 23 and is moved downward by lifting lead 28 band dynamic pressure plate 26, and compression cylinder control mandrel 25 touches cylinder operation makes piston 22 move upward, and automatically raises thus realizing drawing board；In like manner, while compression cylinder control mandrel 25 touches cylinder operation, pin drawing board with hands and be pressed downward against, piston 22 can being made to move downward, automatically reducing thus realizing drawing board；Connecting rod 27 lower end is bolted on connection seat 24, and upper end is connected with drawing board angular adjustment apparatus 4.
Described drawing board bracket is made up of stationery bar 31, montant 32, connection supporting rod 33, cross bar 34 and meniscus 35, wherein montant 32 is two, stationery bar 31, connection supporting rod 33, cross bar 34 set gradually from top to bottom, two ends are fixing with montant 32 respectively to be connected, constituting drawing board carriage frame, meniscus 35 is arranged on lower section in the middle part of connection supporting rod 33.
Described stationery bar 31 is concave groove structure, can place the stationery such as drawing pencil, rubber, ruler, compasses, facilitate student to use；The bottom of stationery bar 31 is concordant with the bottom of two montants 32, and upper end exceeds two montant 32 upper end 20-35mm, in order to block drawing board, it is prevented that its landing.
See Fig. 3, described drawing board angular adjustment apparatus 4 is made up of foot-operated 41, lead 47, even part set 42, axle 43, spring 44, friction plate 45, pulley 46, wherein connect part set 42 to fix with friction plate 45 and be connected, even part set 42, friction plate 45, meniscus 35, connecting rod 27 are sleeved on axle 43, matched in clearance between axle 43 and meniscus 35, in order to the two is freely slidable；Adopt interference fit between axle 43 and connecting rod 27, be fixed as one therebetween；Spring 44 is sleeved on axle 43, between axle 43 end shoulder and friction plate 45, friction plate 45 is close on meniscus 35 under spring 44 pressure effect, it is ensured that the two can not produce relative sliding；Foot-operated 41 are fixed on base 1, and lead 47 one end is fixed with foot-operated 41, and the other end is fixed with even part set 42 by pulley 46, and pulley 46 is fixed on connection seat 24 by pulley bracket.
See Fig. 4, between described friction plate 45 and axle 43 adopt gear shaft connected mode, friction plate 45 can only horizontally slip on axle 43 and can not axial rotation；Seeing Fig. 5, friction plate 45 and be provided with face gear-like groove between matched meniscus 35, to increase frictional force, it is ensured that under spring 44 acts on, the two does not produce relative sliding for it.
Drawing board altitude mixture control realizes principle: foot is stepped on lifting foot-operated 23 and moved downward by lifting lead 28 band dynamic pressure plate 26, and compression cylinder controls mandrel 25 and touches cylinder operation and makes piston 22 move upward, and automatically raises thus realizing drawing board, unclamps foot and step on and namely stop after putting in place；In like manner, control while mandrel 25 touches cylinder operation, to pin drawing board with hands and be pressed downward against, piston 22 can being made to move downward, automatically reducing thus realizing drawing board at compression cylinder, unclamp foot after putting in place and step on and namely stop.
Drawing board tilt adjustment realizes principle: under normal circumstances, and friction plate 45 is close together with meniscus 35 under the effect of spring 44 pressure, can not produce therebetween relative motion, and drawing board angle can not adjust.When needs adjust drawing board angle, foot is stepped on foot-operated 41 and is driven even part set 42 to overcome spring 44 pressure to be moved to the left by lead 47, pulley 46, friction plate 45 is made to separate (now spring 44 is compressed) with meniscus 35, move drawing board bracket with hands and can arbitrarily adjust drawing board inclination angle, after being adjusted in place, unclamp foot-operated.
