Abstract

The utility model provides the novel and applicable multifunctional angle drawing ruler of a marking tool for various angular marking and dimension measurement. The ruler frame of the multifunctional angle drawing ruler is composed of two boards having graduation lines, rulers (2) (3) whose middle part is provided with grooves and are provided with angle lines, wing bolts (4) (5) and a handle (6). The ruler can measure and draw various line segments and angles, and the measurement and drawing are collected to integration. The utility model is used in various material workpieces and teaching, and has the advantages of complete function, convenient carryover, fast drawing speed and relief labor strength.

Description

Multifunctional angle drawer

The utility model is a kind of at metal material, lucite, timber, draws, measures the instrument of angle line and sizing in the teaching.

China rules in the angle of all kinds of workpiece, in the sizing, and general use amount hornwork, graphometer, 30 °--60 ° and 45 ° of set squares, universal bevel protractor.Above-mentioned several instrument has become the general utility tool of drafting, tolerance angle, and these instrumental functions are single and the aspect of mutual repetition, cover organic (wooden) set square arranged again, effective scale does not wait, and its 90 ° of angles equate, also need graphometer if draw the above-mentioned angle in addition of tolerance, protractor, bevel protractor.To sum up all there is inconvenience in apparatus in portably using.

The purpose of this utility model is to be processing metallic, lucite, timber, makes a kind of amount scoring tool in the teaching.Utilize the chi framework ［ 1 ］ of this chi directly to intercept and tolerance, draw line segments, loosening wing bolt ［ 4 ］, ［ 5 ］ utilize two bevel protractors ［ 2 ］, and chi ［ 3 ］ moves up and down mensurable and draws angle line.

The utility model is achieved in that many functions with active angle marking-out rule collection ruler, bevel protractor are one, will measure, the line drawing combination.Its front of chi framework ［ 1 ］［ 7 ］, above ［ 8 ］ be carved with the graduation mark of 0--400 millimeter, use when tolerance and line, the middle part of chi framework ［ 1 ］ front-back has long 402 millimeters, wide 6.2 millimeters notch ［ 11 ］ can make M6 wing bolt ［ 4 ］, ［ 5 ］ move left and right.The middle part, back of chi framework ［ 1 ］ has long 402 millimeters, wide 12.5 millimeters, dark 5 millimeters deep gouge ［ 13 ］, for two wing bolts, pad is in interior operation, and the centre of the upper and lower surface of chi framework ［ 1 ］ has long 402 millimeters, wide 5.5 millimeters notch ［ 12 ］, be provided with bevel protractor ［ 2 ］, ［ 3 ］ in the notch, connect, move angle chi ［ 2 ］, ［ 3 ］ tolerance, drafting angle with two wing bolts ［ 4 ］, ［ 5 ］.Each long 200 millimeters of bevel protractors ［ 2 ］, ［ 3 ］, wide 40 millimeters, thick 5 millimeters, its head is cut into 30 ° of shapes, afterbody be cut into 90 ° with 45 ° of shapes, bevel protractor ［ 2 ］, ［ 3 ］ specification are identical.

Characteristics of the present utility model: improve the speed of drawing, measuring angle and size, reaching saves time reduces labor intensity, and for tolerance, line on various materials and the workpiece provide convenience, this chi is simple in structure, easily makes, and cost is lower, and is easy to carry.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is a front view of the present utility model.

Fig. 2 is a vertical view of the present utility model.

Fig. 3 is the partial sectional view of wing bolt.

Many with reference to Fig. 1 with active angle marking-out rule, long 450 millimeters of chi framework ［ 1 ］, wide 40 millimeters, high 20 millimeters, chi framework ［ 1 ］ is 7 millimeters by the two boards face thickness, two is provided with the generous two bed course pieces that are equal to of two block lengths and forms, chi framework ［ 1 ］ is carved with scale and otch, can be used as the benchmark fixed ruler, lean against on the straight object or coincide with on the straight line, loosening wing bolt ［ 4 ］, ［ 5 ］, decapacitation tolerance is drawn outside 0 ° of-90 ° of angle, the circumferencial direction of 0 ° of-90 ° of position (about) unitary rotation uses active angle marking-out rule more, can draw 90 ° of-180 ° of angles of tolerance, the angles in 360 ° of angular ranges all can be drawn and measure as stated above.

Fig. 2 is a vertical view of the present utility model, reflect this metering scale above chi, wherein be carved with 0 °-90 ° angle groove ［ 9 ］, ［ 10 ］ on the bevel protractor ［ 2 ］ of chi framework ［ 1 ］, ［ 3 ］ positive inverse plate surface, two chis middle part has long 150 millimeters, wide 6.2 millimeters notch ［ 14 ］, ［ 15 ］, two bevel protractors ［ 2 ］, ［ 3 ］ can move up and down in the chi framework, and are required by work, two bevel protractors can be decided angle simultaneously, draw the angle line of tolerance different size.

Handle ［ 6 ］ adopts the chromium plated handle, and long 70 millimeters, wide 15 millimeters, every has 2 holes, is fastened on screw above the forward, central part of chi framework ［ 1 ］, is easy to carry, and is beneficial to stressed during use.

With reference to Fig. 1, connection angle chi ［ 2 ］, the M6 wing bolt ［ 4 ］ of chi ［ 3 ］, ［ 5 ］ they are standard component with flat shim, all operations in the deep gouge ［ 13 ］ of chi framework ［ 1 ］ back of bolt tail and pad.

Fig. 3 is the broken section of wing bolt ［ 4 ］, ［ 5 ］, has shown architectural feature, and these two wing bolts are in notch ［ 12 ］, and operation in the deep gouge ［ 13 ］ is drawn the tolerance angle according to angle square is moved.

How to make white or yellow cover, black graduation mark with active each face of angle marking-out rule.

Many with active angle marking-out rule metal material, the ABS engineering plastics, lucite, timber is made.
