Abstract
The utility model relates to study article field, particularly a kind of ruler.This ruler comprises ruler body, is all carved with scale at the two ends up and down of ruler body upper surface, is provided with a boss in the upper end at the ruler body back side, the lower end of described boss and the distance≤1/4 ruler width of ruler body top edge; Be provided with a slideway in the lower end of ruler body, activity grafting one set square on slideway, one end of described slideway flushes with ruler " 0 " graduation mark, and the other end of described slideway flushes with the maximum scale line of ruler.This ruler is simple and practical, when can avoid line, chi limit and paper is infected with a water or pen and ink, ensure that the clean and clear of chi limit and paper.
Description
(1) technical field
The utility model relates to study article field, particularly a kind of ruler.
(2) background technology
Ruler is as a kind of common study article, essential in teaching and study.Present study chi is general shorter, and structure is simple, function singleness; And, with often running into a water during ruler setting-out or pen and ink leaving cut because being infected with chi limit, affecting the clean of ruler and paper and problem clearly on paper.
(3) summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides a kind of rational in infrastructure, simple and practical ruler.When this ruler can avoid line, chi limit and paper are infected with a water or pen and ink, ensure that the clean and clear of chi limit and paper; This ruler can also measure longer line segment or article, and is easier to picture vertical line, solves problems of the prior art.
The utility model is achieved by the following technical solution:
A kind of ruler, comprises ruler body, is all carved with scale at the two ends up and down of ruler body upper surface, be provided with a boss in the upper end at the ruler body back side, the lower end of described boss and the distance≤1/4 ruler width of ruler body top edge; Be provided with a slideway in the lower end of ruler body, activity grafting one set square on slideway, one end of described slideway flushes with ruler " 0 " graduation mark, and the other end of described slideway flushes with the maximum scale line of ruler.
The shape of described boss lower end is arc.
The beneficial effects of the utility model are: the edge of this ruler upper rear portion adopts boss design, while not affecting ruler back side steadiness, this end face of ruler and paper can be made to keep certain distance, can not contact, thus a water or pen and ink are attached to chi limit and then adhere to cut that paper causes and pollute when well avoiding picture straight line, ensure that the clean and clean of chi limit and paper; The ramp design of ruler lower end, can ensure the line segment that measurement that the set square by slideway is installed continues is longer and article; Because set square slides at ruler lower horizontal, vertical line can be drawn more easily.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the perspective view of the utility model embodiment 1;
Fig. 3 is Fig. 2 side, sectional structural representation;
Fig. 4 is the perspective view of the utility model embodiment 2;
Fig. 5 is Fig. 4 side, sectional structural representation.
In figure, 1 ruler body, 2 boss, 3 slideways, 4 set squares.
(5) detailed description of the invention
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
Embodiment 1, as Figure 2-3, this ruler comprises ruler body 1, all be carved with scale at the two ends up and down of ruler body 1 upper surface, be provided with a boss 2 in the upper end at ruler body 1 back side, the lower end of described boss 2 and the distance of ruler body 1 top edge are 1/4 of ruler width, a slideway 3 is provided with in the lower end of ruler body 1, activity grafting one set square 4 on slideway 3, one end of described slideway 3 flushes with ruler " 0 " graduation mark, and the other end of described slideway 3 flushes with the maximum scale line of ruler.
The design of boss 2 in above structure, when ensure that pressing nose bar rules preferably, blade bottom surface will be caused steadily not affect mapping because of the design of back side boss 2, this boss 2 makes the top edge at ruler body 1 back side and paper keep certain distance, preventing pen and ink or the water from polluting chi limit when ruling along chi limit, avoiding pen and ink on chi limit or ink leaves cut on paper and affects the clean and clear of paper simultaneously; Be provided with a slideway 3 in the lower end of ruler body 1, activity grafting one set square 4 on slideway 3, one end of described slideway 3 flushes with ruler " 0 " graduation mark, and the other end of described slideway 3 flushes with the maximum scale line of ruler.When longer line segment measured by needs, ruler 0 scale is aimed at line segment top, then set square 4 to slideway 3 rear end on slip slideway 3, fix set square 4, ruler body 1 is slid into slideway 3 front end by the slideway 3 bottom it contact with set square 4, then fix ruler body 1, set square 4 is slid into slideway 3 rear end, measurement like this, to line end, is multiplied by pendulous frequency according to chi length and is obtained institute's profile section overall length.In addition, set square 4 auxiliary under, vertical line can be drawn more easily.
Embodiment 2, as illustrated in figures 4-5, this ruler comprises ruler body 1, all scale is carved with at the two ends up and down of ruler body 1 upper surface, a boss 2 is provided with in the upper end at ruler body 1 back side, the shape of described boss lower end is arc, and the lower end of described boss 2 and the distance of ruler body 1 top edge are 1/5 of ruler width; Be provided with a slideway 3 in the lower end of ruler body 1, activity grafting one set square 4 on slideway 3, one end of described slideway 3 flushes with ruler " 0 " graduation mark, and the other end of described slideway 3 flushes with the maximum scale line of ruler.
Arc is designed to the bottom of convex platform 2, the two ends at the ruler back side and paper contact area can be made to strengthen, thus better ensure that the stability of pressing blade bottom surface when nose bar is rule, this boss 2 makes the top edge at ruler body 1 back side and paper keep certain distance, preventing pen and ink or the water from polluting chi limit when ruling along chi limit, avoiding pen and ink on chi limit or ink leaves cut on paper and affects the clean and clear of paper simultaneously; Slideway 3 and the set square 4 of ruler body 1 lower end design, and can ensure the line segment that ruler measurement is longer or article and assist to make vertical line, and measurement and using method, as embodiment 1, no longer describe in detail herein.
The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
