Abstract

The utility model relates to a light drawing machine. Both ends of a drawing board are respectively provided with a light guiding rail groove. The upper part and the lower part of the guiding rail groove are respectively provided with a pulley wheel. Through the skill connection and transmission of a nylon wire, a left ruler base and a right ruler base in the guiding rail groove simultaneously move from top to bottom, which drives an I-shaped main ruler and an auxiliary ruler to freely move in a two-dimensional range on the surface of the drawing board. A task for drawing is exactly completed with high efficiency. The utility model has the advantages of simple and light structure, and low cost. The light drawing machine conforms the habit of a person who draws a figure, and can be put on a desk to be used. The angle is adjustable. The light drawing machine is different from a parallel rule pulley wheel device which is widely used. A rope does not pass through the surface of the drawing board. A main ruler block and an auxiliary ruler block can be quickly assembled and disassembled, which is convenient to load and take drawing paper. The utility model can probably become a late-model product for a drawing board T-shaped ruler and a heavy guiding rail type rotating arm type drawing machine.

Description

Light drawing machine with rope transmission

The utility model relates to draw the by hand light-duty draught machine of rope drive of usefulness of all kinds of engineers and technicians of a kind of confession.

Existing all kinds of manual draught machine, complex structure, heaviness, machined piece required precision height can not be put on the what desk and use, and also do not meet most illustrators and begin to learn the custom that forms when drawing, and the cost high efficiency is low.Some novel and portable draught machines of machine examination rope do not have the peculiar kind of drive of the utility model yet as calculated.The structure of only a kind of light draught machine application number 89219908.3 that steel wire rope arranged also with the utility model fundamental difference.It is not can solve transmission or the structure problem that a scale (main scale) moves horizontally up and down and can't draw the horizontal line of growing fast and accurately because of no parallel rule to seem that efficient is low that other majority still has the complicated wherein most subject matters of parts such as the different guide rail pivoted arm of structure.Application number is that 90200170.1 parallel rule draught machine is the soft transmission of flute profile band in addition, but structure is still drawn facility than the vertical line of not establishing move left and right on complicated and this machine parallel rule, oblique line.

The purpose of this utility model is to provide a kind of light and handy cost simple in structure inefficient high draught machine, can put on the common desk of what, also can put on the adjustable special-purpose frame of the liftable rotational angle of what special use, and meet the custom that most illustrators just form in class hour.

The utility model is achieved through the following technical solutions: at two ends, the draught machine left and right sides respectively by adorning a light-duty guide-track groove, guide-track groove be fixed with pulley up and down, but rod support that a crossheading slides up and down is respectively arranged in the guide-track groove in order to the fixed lateral main scale, two rod supports are walked around pulley by rope and are linked the transmission (see figure 1), concrete mode of connection is: rope such as nylon wire that elastic extension low-intensity of left end rod support upper fixed is high, turn right for one that up walks around top in the sister block of guide-track groove upper end, a pulley walking around top, right-hand member top again down pastes the rod support outside and crosses the single-sheaved block of walking around the right-hand member bottom again and up fix with right-hand member rod support bottom for 180 °.A nylon wire is fixed on the top of right-hand member rod support simultaneously, and is opposite with the left side equidirectional around the knot method.One of them rod support moves up and down like this, and another rod support of transmission by linking rope is also with moving up and down at present, and the horizontal main scale that is installed on two rod supports about on the chart board (or before and after claiming) is moved horizontally.Guide rail is arranged on the main scale, but the secondary chi of move left and right is housed on the guide rail, commonly used is set square, angle lattice commonly used and pattern model lattice commonly used is arranged so that draw chamfering line hatching etc. on it.Set square can also be changed into L type chi or ruler in order to draw the oblique line of vertical line and various angles.

(claim front and back when keeping flat) about the main scale and move horizontally in order to draw horizontal linear that secondary chi move left and right is in order to draw the oblique line of vertical line and various angles, the major-minor chi can move freely in the two dimensional range on chart board, just can finish the drafting of various straight line line segments.Also can take off secondary rod support, change common set square into and lean against on the main scale and use.Can also cancel chart board, and remainder is supporting as the product person that sold to the chart board.

The utility model can also install additional with what and go up the fixing frame that also can easily align angle toward table, also can mix console mode adjustable housing and seat.Being connected of main scale and rod support adopt pin quick fixation structure, figure panel edges that the drawing clamping device is set and get main scale and drawing with convenient dress.

The utility model is because just installed light-duty guide-track groove and pulley and linked transmission cleverly by rope, so cost simple in structure is low at common chart board two ends.Can be placed directly on the desk and use, also can put on the adjustable frame of the liftable rotational angle of what special use and use, meet most illustrators and begin to learn the custom that forms when drawing.Owing to needn't use hand guiding ruler, nose bar, also needn't worry the error that guiding ruler does not sternly produce, add that a word crossfoot connects chart board, thereby can improve drawing efficiency and quality.

The kind of drive of the present utility model is same as never that the wider parallel rule pulley cable traction device of present application---the rope of this device passes through from the chart board face, and parallel rule is difficult for, and dress is got and the dress that influences drawing is got.This also is a core of the present invention.

Do below in conjunction with drawings and Examples and to describe in further detail:

Fig. 1 is the transmission principle schematic diagram, and Fig. 2 is for omitting the front view of adjustable housing.

The present invention is equipped with guide-track groove (1) at the two ends, the left and right sides of chart board (2), the sister block (9) of tape spool and the single-sheaved block (10) of lower end are equipped with in the upper end of guide-track groove, a rod support that moves up and down along guide-track groove (8) respectively is housed in two guide-track grooves, the fixedly quick-clamping pin of main scale (3) usefulness is arranged on the rod support, and the main scale two ends are provided with the hole of suit pin.After fly rope (11) installs by the binding method of transmission schematic diagram, main scale just can be on the chart board face level move up and down and can easily adorn and get.There is guide-track groove (4) secondary rod support (7) to be installed on it on the main scale, secondary rod support is provided with dial, the center is that the quick-clamping fastener shaft has gland in order to fixed joint chi bar (6) on it, the rotation of can stretching of secondary chi bar, the front end of secondary chi bar also is provided with angle dial and quick clamping device in order to be connected and fixed secondary chi (5), secondary chi can be around the rotation of the dial center of secondary chi bar front end, secondary chi can be joined a plurality of as set square, ruler, L type chi etc., set square is provided with pattern model hole commonly used and comprises 30 °, 45 °, 60 ° of line diamond pattern holes are with the convenient chamfering line of drawing, hatching and figure commonly used.
