Abstract
The utility model relates to teaching appliances for drawing, in particular to a multipurpose drawing ruler for the fields of garden drawing and the like. The multipurpose drawing ruler comprises four supporting rods and a scribing ruler, wherein the four supporting rods are connected end to end to form a quadrangle, and the scribing ruler is arranged on a diagonal of the quadrangle and is hinged to the supporting rods. The lower end of the scribing ruler is hinged to the hinged portion of the two adjacent supporting rods through a locating pin, a scribing rail is arranged in the center portion of the scribing ruler, the hinged portion of the other two supporting rods slides in the scribing rail, a protractor is further hinged to the locating pin, the locating pin is hinged to the middle portion of the protractor, the two supporting rods hinged to the locating pin are provided with a starting line I and a starting line II respectively, and the locating pin is provided with an annular groove I, an annular groove II, an annular groove III and an annular groove IV, wherein the annular groove I, the annular groove II, the annular groove III and the annular groove IV form a set with the two supporting bars, the protractor and the scribing ruler. The service life of the multipurpose drawing ruler is prolonged, and the multipurpose drawing ruler is easier and more convenient to operate.
Description
Technical field
[0001] the utility model relates to a kind of teaching aid of the usefulness of charting, and relates to a kind of drawing multipurpose ruler of the fields such as demonstration of drawing for gardens specifically.
Background technology
[0002] when blackboard was drawn explanation, logical product need be drawn with wooden protractor, set square etc., and operation comparatively bothers like this.The existing method of doing angular bisector normally adopts construction with ruler and compasses, adopt comparatively difficulty of construction with ruler and compasses at blackboard, and the bisector error of drawing is bigger, can stay the vestige of mapping at blackboard in the bisector that draws, need carry out wiping again, this method is very loaded down with trivial details, and the efficient of teaching is very low, what be unfavorable for imparting knowledge to students carries out smoothly, if operate inaccurate words, and the quality of influence education.The patent No. is a kind of multipurpose ruler that 201220061070.4 patent adopts a kind of folding rule and compasses combination, this ruler has solved this difficulty to a certain extent, but at the alignment pin position since pole, marking-out rule and protractor when in use, friction back and forth, time is more long, the protractor wearing and tearing is more severe so, also can influence the quality of education at last to a certain extent.
Summary of the invention
[0003] the purpose of this utility model is to overcome deficiency of the prior art and provides a kind of long service life, drawing multiservice car simple to operate.
[0004] the purpose of this utility model is achieved in that a kind of drawing multipurpose ruler, comprise tetragonal four poles of the hinged formation of head and the tail, be arranged on quadrangle diagonal and the marking-out rule hinged with pole, the marking-out rule lower end is with wherein adjacent two pole hinge point are hinged by alignment pin, described marking-out rule centre is provided with scribe lanes, two other pole hinge point is slided in scribe lanes, also be hinged with protractor on the described alignment pin, and it is hinged with its centre, be respectively arranged with starting line one and starting line two on hinged two poles of described and alignment pin, described alignment pin is provided with respectively and two poles, protractor, marking-out rule forms the annular groove one of suit, annular groove two, annular groove three, annular groove four.
[0005] length of described four poles is identical.
[0006] the zero graduation line of described protractor aligns with starting line one.
[0007] described annular groove one, annular groove two, annular groove three, the annular groove fourth class are apart from layout.
[0008] the utility model is on the basis of 201220061070.4 technical scheme in the patent No., alignment pin is designed to the structure that has with two poles, protractor, cannelure that marking-out rule is corresponding, this structure is fixed two poles, protractor, marking-out rules on the one hand, can directly not contact between two poles, protractor, the marking-out rule on the other hand, therefore reduced the friction between two poles, protractor, the marking-out rule, thereby prolonged the service life of this multipurpose ruler, make operate more simple and convenient.
Description of drawings
[0009] Fig. 1 structural representation of the present utility model.
[0010] Fig. 2 is the structural representation of alignment pin.
The specific embodiment
[0011] as Fig. 1, shown in 2, a kind of drawing multipurpose ruler, comprise tetragonal four poles 3 of the hinged formation of head and the tail, be arranged on quadrangle diagonal and the marking-out rule 2 hinged with pole 3, marking-out rule 2 lower ends are with wherein adjacent two pole 3 hinge point are hinged by alignment pin 6, described marking-out rule 2 centres are provided with scribe lanes 1, two other pole 3 hinge point are slided in scribe lanes 1, also be hinged with protractor 5 on the described alignment pin 6, and it is hinged with its centre, be respectively arranged with starting line 1 and starting line 27 on hinged two poles 3 of described and alignment pin 6, described alignment pin 6 is provided with respectively and two poles 3, protractor 5, marking-out rule 2 forms the annular groove 1 of suit, annular groove 29, annular groove 3 10, annular groove 4 11.
[0012] length of described four poles 3 is identical.
[0013] the zero graduation line of described protractor 5 aligns with starting line 1.
[0014] described annular groove 1, annular groove 29, annular groove 3 10, annular groove 4 11 equidistant placement.
[0015] described two poles 3, protractor 5, marking-out rule 2 are sleeved on respectively in annular groove 1, annular groove 29, annular groove 3 10, the annular groove 4 11 successively, and two pole 3, protractor 5, marking-out rule 2 can rotate at annular groove 1, annular groove 29, annular groove 3 10, annular groove 4 11 respectively, and can not produce friction each other, make that rotation is convenient.
[0016]
