Abstract

The utility model discloses a multipurpose drawing ruler for drawing, comprising a zoom type longitudinal ruler and a zoom type longitudinal ruler. The utility model can replace a T square, a parallel ruler, a straightedge, a set square and a protractor during common drawing and can be matched with drawing boards with the multiple models after adjusted. The parts of the drawing ruler are simple and reasonable. The utility model has the advantages of convenient manufacture, low cost and strong applicability. One ruler is multipurpose, and the drawing ruler is a tool used in building, machine, drawing and other various precise drawing.

Description

Multipurpose drawing ruler

The utility model belongs to the drawing instrument.

Existing common drawing rule generally has T-square, parallel rule, ruler, set square, protractor etc.Cooperate with other drawing instruments, can on chart board, draw drawing symbols such as straight line, oblique line, curve and form various figures.The another kind of large-scale draught machine of then forming by metal drawing rule, track and chart board, support etc.

The deficiency of above-mentioned common drawing rule has: the first, and T-square is owing to have only chi head rest figure edges of boards to slide, and it is parallel mobile with the hands to push away, draw in row, when drawing lines, needs to hold blade with left hand the service efficiency of hand during the influence drawing.The second, parallel rule carries out flat pattern by four pulleys with the backguy tensioning and moves, and the blade instability moves and occurs shaking phenomenon easily during line, influences mapping effect.Described another kind of large-scale draught machine is then heavy, the cost height, and efficient is not high, and can not satisfy the needs that drawing is made long lines.

The purpose of this utility model is, a kind of drawing rule that has improved is provided, replenishing above-mentioned deficiency, and can the many usefulness of a chi, the similar material of available lucite, plastics, timber and performance is made.

The utility model is by horizontal chi and longitudinal ruler is supporting forms.Laterally chi by about two chi heads and blade forms the laterally parallel mobile horizontal line of doing on chart board; Longitudinal ruler by the chi head and fixedly blade and movable blade form, parallel longitudinal moves and makes vertical bar and oblique line at any angle on chart board, more than two kinds of chis cooperate and can make arbitrary line at drawing.

Description of drawings

Fig. 1 is the schematic perspective view of drawing rule.

Fig. 2 is the top plan view of drawing rule.

Fig. 3 is the A-A cut-away view of horizontal chi.

Fig. 4 is the B-B cut-away view of longitudinal ruler.

As shown in Figures 1 to 4, of the present utility modelly many form horizontal chi by fixed ruler head (1), blade (2), adjustable rule head (3) with drawing rule; By chi head (4), guide margin (5), fixedly blade (6), movable blade (7) are formed longitudinal ruler.Laterally comprise screw rod (12), nut (8), the pad (11) that is connected with adjustable rule head (3) in the chi; Longitudinal ruler comprises screw rod (14), nut (9), the pad (10) that is connected and fixed blade (6) and movable blade (7).Laterally chi head (1) becomes 90 ° to fix in the chi with blade (2), Cheng Po limit, blade (2) both sides, plane, the length graduation mark is scribed on the both sides, baseplane, blade (2) has 2～3 oval screw holes with adjustable rule head (3) junction, the position in hole is corresponding with 0#～2# chart board length, screw rod (12) is fixed in adjustable rule head (3) center and passes the screw hole (13) and nut (8) of blade (2), pad (11) connects, fixed ruler head (1) and the as far as possible close figure panel edges of adjustable rule head (3) can be stablized horizontal chi when fastening, the easy on and off parallel sliding is advisable.Longitudinal ruler chi head (4), guide margin (5) become with fixing blade (6) 90 ° fixing, the distance of chi head (4) and guide margin (5) with as far as possible near horizontal blade (2) and make longitudinal ruler can freedom, stably left and right sides parallel sliding is advisable.Fixedly (6) one of blades are half garden shape, and there is hole, a garden at heart place in garden; Blade (6) is gone up horizontal edge Cheng Po limit, and lower plane half garden shape one end is with the Kong Weiyuan heart, and 360 ° of garden shape graduation marks and cross centre line are scribed in the edge.Movable blade (7) one ends become half garden shape, the boring of garden heart place, and the length graduation mark is scribed on the both sides, baseplane; Cheng Po limit, both sides, last plane and be that the intersection center line is scribed at the center with the hole, garden.Screw rod (14) passes movable blade, (7), fixedly blade (6) hole, garden cooperates fastening with pad (10), nut (9).Unscrew nut (9) during use, movable blade (7) is regulated the back in 180 ° of scopes fastening, to draw on the drawing lines at any angle.

Embodiment:

Chi head (1), (3), (4), guide margin (5), blade (2), (6), (7) of making the regulation shape by accompanying drawing with the thick transparent organic glass of 4mm, and by accompanying drawing and explanation boring, scribe required graduation mark, surface requirements is smooth.

Become 90 ° to glued joint to become integral body with blade (2) chi head (1), fixedly blade (6) becomes 90 ° to glued joint to become integral body with chi head (4), guide margin (5), and screw rod (12) is fixing with adjustable rule head (3), and screw rod (14) is fixed with movable blade (7).

Passing hole (13) with the fixing screw rod (12) of adjustable rule head (3) cooperates fastening with pad (11), nut (8).The screw rod (14) fixing with movable blade (7) penetrates the fixedly hole, garden of blade (6), cooperates fastening with pad (10), nut (9) after regulating angle.

During use, chi head (1) and adjustable rule head (3) should be close to the figure panel edges, with can be free, parallel sliding stably, blade does not rock is advisable.Longitudinal ruler should be controlled crack between chi head (4), guide margin (5) and blade (2) edge, little with the gap, can be free, stably left and right sides parallel sliding is advisable.

Horizontal chi cooperated with longitudinal ruler place on the drawing board, can regulate the angle of longitudinal ruler body (7) and blade (2) when needing; As the drawing board of different model, the distance that can regulate horizontal chi head (1) and adjustable rule head (3) makes it to adapt to chart board length.The laterally replaceable use in blade (2) both sides has same function.Handle stable up and down, the parallel sliding freely of horizontal chi with left hand, stable about longitudinal ruler, parallel sliding freely.

Cooperate with other drawing instruments with the above-mentioned drawing rules of using more, can draw lines required on the drawing.
