Abstract

A kind of U-shaped multifunctional adjustable rule is combined by main body chi and two adjustable rules and card.Rotate up 90 ° after an end adjustable rule is pushed open in the main body chi abdomen and become " T " word chi; The other end also can be pushed open or all extract out, or connects to form set square with an end, digs certain big protractor hole eye on main body chi two sides, engraving respectively teaching with and general consumption footmark degree, melting protractor, set square, plagiocephaly chi, ruler " T " word chi is one.Except that having general chi function, also be used for engineering detecting, tolerance object, check and correction numeral, restriction coating scope and classroom instruction also can integral body or bulk-breaking uses.

Description

U type multifunctional adjustable rule

The present invention a kind ofly closes, divides device, and has multiple function, and (except that generality is used) especially detects engineering matter, the tolerance object, and the check and correction numeral controls a kind of adjustable rule of coating scope and classroom instruction.

At present, the known various chis of using, although purposes is different, usage also is single, particularly touch the detection engineering, tolerance object, check and correction numeral and classroom instruction, general chi can not be comprehensive, and supporting use or inconvenience are carried, thereby bring great inconvenience and difficulty to the user.

The object of the invention provides a kind of multifunctional adjustable rule, it not only has the function of general chi, and can be used for classroom instruction, detect construction quality, tolerance object, check and correction numeral, restriction coating scope, melt protractor, ruler, set square " T " word chi, the plagiocephaly chi is an one, use not only capable of being combined but also can bulk-breaking use.

The present invention is achieved in that it is by main body chi (main body chi two sides is carved with classroom instruction and general two kinds of model angulation scales using respectively) and length, two adjustable rules that width is different and card are formed, (the main body chi is by A to the main body chi, the corresponding moulding in B two sides, the formation abdominal cavity) rotates up 90 ° after the adjustable rule of an end is pushed open in the abdomen and become " T " word chi, be used for proofreading numeral, detect engineering or other object vertical extent, its adjustable rule centre joint can be used to limit the coating scope, more can directly use " T " word chi, main body chi plagiocephaly, " T " word chi plagiocephaly or ruler draw respectively or intercept 180 °, 90 °, the angle of 60 ° and 30 °, extract full adjustable rule out, make its opening part put main body chi post nail and connect to form big set square with " T " word chi, and the teaching protractor is used for classroom instruction together, the complete use capable of being combined of whole chi also can be extracted adjustable rule out and " T " word chi and usefulness.Two adjustable rules horizontal direction arranged side by side is pushed to make it to become a plagiocephaly chi in the main body chi abdomen when folding, and reaches chi usefulness in many ways, the purpose that many chis are applied flexibly.

Owing to adopt above-mentioned main case, can be on the basis that replaces general chi, be used for classroom instruction, detect construction quality, check and correction numeral, control coating scope, can combination use also detachment use, alleviate user's burden greatly and simplify teaching process, improve detection efficiency, its element is few simple in structure easy to carry.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 5 U type multifunctional adjustable rule parts drawing

Among the figure 1,2,3,4, all be that post nail 5 is that half adjustable rule 6 is that main body chi 7 is that general protractor 8 is that full adjustable rule 9 is that full adjustable rule upper clamp slice 10 is that the eye 11,12 that is used for pushing away chi on the main body chi A face all is that the main body chi A face upper shed place 13 half adjustable rule centres joint 14 classroom instruction protractors 15 lugs are along 16 full adjustable rule opening part 17 card opening parts 18 card eyes 19 protractor hole eyes, 20 main body chi abdomen inner opening places

At Fig. 1-1,1-2 and Fig. 2-1, and protractor hole eye among the 2-2 (19) A, B two sides equal and opposite in direction, general quantity footmark degree (7) are interior, and classroom instruction angulation scale (14) does not overlap outside mutually, and scale is dark and clear, varies in color, and it is big that contrast is wanted, and contrast obviously.Other does not mark main body chi B face (Fig. 2-2) limit vertical direction mark long measure, and classroom instruction can be used Fig. 2-2 protractor (14).Earlier draw a ray in the plane when drawing certain number of degrees with chi, determine a bit, again with hand in protractor the hole respectively after two ends are pushed half adjustable rule (5) and full adjustable rule (8) open, to fix a point on protractor (14) the center of fiqure aligning ray, and allow the scale of being looked on this ray and the protractor overlap, draw a horizontal line along main body chi limit then, this angle that joins is exactly drawn angle.If drawn angle covered sight line by chi itself, the obtuse angle that can draw earlier deducts a certain amount of angle again, and gained poor is drawn angle.Also directly utilization hornwork top 0-40 ° of shelves scale draws.Otherwise take measurement of an angle then.(among the 1-2 figure) general quantity hornwork (7) is surveyed drawing method and is used identical with other protractor.

In Fig. 3-1, should the prune thickness of card (9) of the interior survey of main body chi (6) opening part (11) rotates in order to card.

In Fig. 3-2 main body chi (6) and half adjustable rule (5), the big set square that is combined into after full adjustable rule (8) and card (9) expansion.Earlier push half adjustable rule (5) open and upward opening (20) half-twist makes it " T " word chi during expansion from protractor hole eye (19), stir card (9) with hand from main body chi (6) eye (10) again and extract full adjustable rule (8) out, along its direction opening part (16) is inserted post (2), rotation card (9) overlaps on the post (3) of first adjustable rule (5) card opening part (18) then.

(A face) opening of main body chi in Fig. 4-1 (12) length should equal the length of post (3) to half adjustable rule (5) top, and the terminal point of main body chi (A picture) opening (11) should equal the distance of post (4) to card opening part (17) to the distance of post (2). Post 1,2,3,4 can be selected the post nail of 1.5 mm dias for use, and " T " word chi centre joint (13) width equals the width of opening part (11) and opening part (12), also equals the diameter of post 1." T " word chi centre joint (13) can limit the coating scope, and it is placed on the plane that needs coating, is stained with pigment with writing brush and is applied to slit (13) and gets final product, and can raise the efficiency and accuracy rate near the required numeral of copying or adding up on the limit anyhow with " T " word chi." T " word chi is near the object edge, inspected object right angle degree, in addition, can also use main body chi (6) plagiocephaly, half adjustable rule (5) plagiocephaly or full adjustable rule (8) and " T " word chi draw respectively or intercept the angle of 180 °, 90 °, 60 ° or 30 °, can launch, and combination accessory uses, also full adjustable rule (8) can be extracted out separately and be used

Earlier that half adjustable rule (5) is downward when drawing in Fig. 4-2, behind the half-twist, horizontal direction advances in main body chi (6) abdomen, more full adjustable rule (8) tack one end is inserted advance in the main body chi (6) after, rotation card (9) is also pressed and is inserted in post (2) and gets final product.Card (9) should be selected indeformable steel material for use, and thick limit is within 1 millimeter.

Fig. 5 is each bulk-breaking of U type multifunctional adjustable rule, the size of chi depends on the size of each bulk-breaking, and main body chi (6) wide is greater than full adjustable rule (5) and the half wide sum of chi (8) of living, half adjustable rule (5) slightly is wider than full adjustable rule (8), and full adjustable rule (8) should be longer than half adjustable rule (5).
