The utility model can also be lay flat on a bracket used as a blackboard usage multi-purpose drawing board. A horizontal ruler assembly used to draw the horizontal line can slide in a vertical v-shaped groove arranged on the bracket. A vertical ruler assembly used to draw the vertical line and arbitrary angles can horizontally slide while the A horizontal ruler assembly is used as the guide track. The slanted angle of the multifunction drawing machine is adjustable within limits.

Description

Multifunction drawing machine

The present invention is a kind of drawing instrument, is simplification and improvement to existing guide tracked draught machine.

Traditional drawing practice is to utilize vertically moving of T-square to draw parallel horizontal line on drawing board, utilizes set square move left and right on T-square to draw parallel vertical line, utilizes the angle of set square to draw 30 °, 45 °, 60 ° oblique line.Draw oblique line at any angle as need, also must be used with the calibration instrument.Therefore, this drawing practice efficient is lower.For overcoming this shortcoming, the guide tracked draught machine of drawing table, drawing board, drawing head has appearred integrating.Have on the head of this guide tracked draught machine two each other the Zhi Chi And at right angle can do at any angle rotation.Head guide rail is along the longitudinal done and is vertically moved, and longitudinal rail can laterally move along the cross slide way that is fixed on the drawing board again, thereby satisfies the basic demand when drawing.The shortcoming of guide tracked draught machine is that complex structure, requirement on machining accuracy are higher, so cost is also high.The object of the present invention is to provide a kind of simple in structure, with low cost, drawing function is identical with guide tracked draught machine, drawing board can doublely be made the multifunctional drawing machine that blackboard uses again.

The invention is characterized in: the multipurpose drawing board that can doublely do the blackboard use lies on the carriage, being used for drawing horizontal horizontal ruler assembly can slide by the vertical V-shaped groove on carriage, the vertical ruler assembly that is used to draw vertical line and arbitrarily angled oblique line is that guide rail horizontally slips with horizontal ruler assembly, can adjust the angle that the multifunctional drawing machine turns forward within the specific limits by the height of adjusting footing.

As shown in Figure 1, the multifunctional drawing machine is made up of carriage (1), multipurpose drawing board (2), horizontal ruler assembly (3), vertical ruler assembly (4), footing (5), hanger (6), little axle (7).

Carriage (1) is a dish-shaped body, and middle partly recessed downwards, its size is more bigger than multipurpose drawing board.A plane of opening is laterally respectively arranged at the frame top of enclosing on left and right both sides, and a V-shaped groove is longitudinally respectively arranged on the plane, and these two V-shaped grooves are parallel to each other, as the guide rail of horizontal ruler assembly.Respectively there is one section projection at two ends on the plane, get off to prevent the landing of the straight chi assembly of water, have an elongated slot on the projection of back, the little axle that is fixed on the multipurpose drawing board can be inserted in the groove, so that raise or take off multipurpose drawing board.In the front of carriage (near this one side of drawing personnel), be a upright frame that encloses, its height is identical with the last plane of multipurpose drawing board, the length of the hanger that its width equals to stretch out on the multipurpose drawing board.On this top of enclosing frame, recessed shallow slot is arranged, downwards so that place some little drawing articles, as pencil, rubber etc.The middle part of enclosing frame will disconnect one section breach, and a horizontal plane is arranged in the breach, and the last plane of this horizontal plane is hanged down 2～4 millimeters than the lower plane of multipurpose drawing board.Have the hole on the plane, so that lock together with multipurpose drawing board.The last plane of enclosing frame and multipurpose drawing board of carriage back is contour.On the bottom surface of carriage, the reinforcement of some projectioies is arranged, the negative area of carriage is divided into several lattice, can lay horizontal ruler assembly (diagonal is laid), vertical ruler assembly, drawing instrument and various pen, rubber, blackboard eraser etc.The height of these reinforcements differs the thickness of a multipurpose drawing board apart from the plane of the left and right sides, after putting multipurpose drawing board, make the last plane of chart board and carriage about two planes on same plane.

Multipurpose drawing board (2) is made with smooth, smooth, on-deformable wood materials.One side is as drawing board usefulness, the compound last layer of another side light color plastic plate, and as plastic blackboard usefulness, the soft pen of available nylon (claiming the blank pen again) is write in the above.Also this simultaneously can be coated blackboard paint, write with common chalk.On this one side of using as blackboard, fix a metal hanger (6), its effect is blackboard can be hung on the wall to use, again can be with multipurpose drawing board and carriage lock together.Doing the one side that chart board is used, each fixes a little axle (7) at the two ends, the left and right sides at rear portion, is inserted in about carriage on two planes in the groove of bossing the center of rotation when raising multipurpose drawing board.

Fig. 2 is the part sectioned view of horizontal ruler assembly (3).Two steel balls (10) that compress with spring (9) respectively are equipped with at two ends in horizontal ruler (8), and its thrust is adjusted by screw (11).Horizontal ruler assembly vertically moves by sliding to do in the V-shaped groove of steel ball on the carriage left and right plane, thereby can draw out parallel horizontal line.Horizontal ruler assembly is to lean on the weight of self to lie on multipurpose drawing board and the carriage, and the time spent can not lifted down and is placed in the carriage.

Fig. 3 is the profilograph of vertical ruler assembly (4).Guiding trestle (12) can horizontally slip on horizontal ruler (8), and spring leaf (13) is in order to eliminate the gap between (12) and (8).Vertical ruler (14) links to each other with guiding trestle (12) with handle (16) by axle (15).After the release handle (16), vertical ruler (14) can serve as that axle is done clockwise or each rotation of 90 ° counterclockwise with axle (15), the angle of rotation be can read by the graduation mark on (12) and (14), vertical line or oblique line at any angle (16) can be drawn after fastening.Vertical ruler assembly can not lift down from horizontal ruler assembly and be placed in the carriage by the time spent.

On the bottom surface at carriage (1) rear portion, the footing (5) that screw thread is made in two ends is housed, regulate the multifunctional drawing machine angle of face tilt forward by the height of regulating (5), make the drawing personnel more laborsaving when work.

In sum, be not difficult to find out that compare with existing guide tracked draught machine, the present invention has the following advantages:

1, satisfying under the prerequisite that requires of drawing, simplified structure significantly, parts machining process is simple, therefore can reduce cost significantly.

2, drawing board has increased function, can doublely make blackboard and use.

3, can make series of products by the size of institute's drawing paper breadth.

4, the multifunctional drawing machine that is used to draw No. 2, No. 3 breadth drawings can be made portable, easy to carry.
