Abstract

The utility model provides an improved plotter, comprising a drawing plate, a parallel rule, and a winding. The utility model is characterized in that four apical angles of the drawing plate are provided with a pulley support. The pulley support is provided with a horizontal section used for fixing and a tilting section with tilting upwards 45 DEG. The front and the back of the tilting section are respectively provided with two pulley wheels. The winding winds each pulley wheel to form an enclosed shape whose inside is connected with the outside. The both ends of the parallel rule are fixed on the winding whose both sides can carry out the move along the same direction and can carry out the up and down parallel move. The improved plotter has the advantages of simple structure, low cost, safe and convenient use, and good adaptability for the drawing board, and without a lifting hammer. The utility model is suitable for drawing use.

Description

A kind of improved plotter

The utility model relates to drawing appliance, and particularly a kind of improved plotter is suitable for drawing and uses.

As everyone knows, the earliest with use to such an extent that the device that charts the most widely is T-square and draughting board, its advantage is simple in structure, and is easy to use, but not enough be that the glacing flatness and the smoothness on the draughting board left side are had relatively high expectations; In addition, do not note slightly in use just can producing deviation.People had invented a kind of drop hammer type plotter afterwards, and it is made up of sash weight, parallel rule, pulley coiling and draughting board.During use, pulley is installed on the upper left corner or the upper right corner of drawing board, to wherein coiling extension sash weight down, walk around the guide wheel at pulley and parallel rule two ends then, link with the messenger wire nail of painting the plate lower end again, the guide wheel of walking around the parallel rule two ends is connected with the messenger wire nail of another inferior horn of drawing board again, and two coilings are 8 fonts on parallel rule.Under the effect of sash weight, parallel rule can be parallel up and down mobile on drawing board.This drawing is the influence that is not subjected to drawing board left hand edge glacing flatness with the advantage of parallel device, is difficult for producing deviation, and uses very convenient.But this plotter deficiency is that people do not note just running into sash weight when walking slightly, makes the injured or broken trousers of hook of shank; In addition, must allow sash weight leave certain displacement in use, so chart board must put and could chart by heavily fortified point, make troubles to the user.Though existing in the prior art a kind of Weight-balancing type plotter, cost is very high, is difficult to popularize, particularly more difficult applying in teaching or training process.

The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of through plotter improved, simple in structure, that cost is low, deviation is few and easy to use.

Fig. 1 is the state diagram after the utility model assembling.

Fig. 2 is the structure chart of Fig. 1 middle pulley support (4).

Task of the present utility model realizes by this way: as depicted in figs. 1 and 2, This plotter includes draughting board (1), parallel rule (2) and coiling (3), it is characterized in that in draughting board (1) Four drift angles on that a shape respectively is housed is identical, symmetrical pulley bracket (4), this pulley Support (4) has the tilting section (6) of a horizontal segment (5) and the 45° angle that is inclined upwardly, and opens at horizontal segment (5) Fixing hole (7) is arranged, and along inclined direction two tangent having are installed in front and back on the front of tilting section (6) The pulley (8) in lead hole, coiling (3) begins to walk around the lower left corner from a pulley of outermost (8) in the upper left corner A pulley (8) of outermost is upwards walked around the interior pulley (8) in the upper left corner, laterally walks around the upper right corner again Interior pulley (8), turn to down the outer pulley (8) of walking around the lower right corner, upwards walk around then the upper right corner Outer pulley (8), the head end by a connector (9) and coiling (3) links together a word at last The left end of chi (2) and outer left side coiling (3) link, and coiling (3) links in its left side and the right.

This plotter is to install like this: the pulley bracket (4) that pulley (8) will be housed with screw is installed in the left and right place, angle of going up of drawing board (1) earlier, the seamed edge of being close to two pulley brackets (4) horizontal segment then with a backguy is fastening good with them again after making them be on the same straight line.The outer pulley (8) of two pulley brackets (4) is determined the installation site of the lower left corner and two pulley brackets in the lower right corner (4) as fulcrum about then using the weight line with top, and they are fastening.To wind the line (3) around to each pulley (8) by above-mentioned method for winding subsequently, and load onto parallel rule (2) at last and get final product.

From Fig. 1 as seen, whole piece coiling (3) is an interlock, in the outer coiling on drawing board (1) left side and the interior coiling on the right is to move in the same way synchronously, so the two ends of parallel rule are anchored on the outer coiling on the left side and the interior coiling on the right just can parallelly move up and down afterwards, have realized the requirement of drawing.The utility model is compared with existing plotter has following advantage:

1, simple in structure, cost is lower.

2, the parallel mobile influence that is not subjected to drawing board dual-side quality of parallel rule (2), the parallel lines deviation of being drawn is few.

3, there is not damage the easily thing of people's leg of drop hammer type plotter, and standing or horizontal drawing, safety easy to use.

4, the utility model is less demanding to drawing board, adaptability is better, when selling, can sell pulley bracket (4), parallel rule (2) and coiling (3), allowing the user select for use suitable drawing board to load onto just can, therefore easy to utilize, be particularly suitable for imparting knowledge to students, training and relatively poorer place use.

When implementing, can by drawing board (1) dual-side place limited block (10) be set at the two ends of parallel rule (2), move to avoid parallel rule (2) both sides.In order to guarantee that coiling (3) does not in use break away from pulley (8), the anti-decylization (10) of coiling can be set at pulley (8).Can establish hole, position, a school (12) position, school plush copper (13) at pulley bracket (4),, walk around the position that position, school plush copper (12) is calibrated two pulley brackets (4) so that pass hole, position, school (13) with a backguy.On two pulley brackets (4) of draughting board (1) lower end, also be provided with guard boom (14), be damaged in case limited slip wheel support (4) is run on the ground.

Claims
