Abstract

The utility model discloses a multipurpose combined stationery which is composed of a foldable ruler (a scale) which is connected by a hinge, a protractor, a compass, a pencil and a set square. The utility model can be conveniently folded and stretched, and the utility model has a basic drawing function. Therefore, only one stationery basically satisfies the learning and working requires of primary and secondary school students and general drawing workers. The utility model is a combined drawing and metering tool which has the functions of the compass, the protractor, the ruler, the scale, the pencil, etc. The utility model has multiple purposes, cabinet volume, simple and compact structure, low price, convenience using and carrying, and is especially suitable for primary and secondary school students.

Description

Use combined stationery more

The utility model relates to a kind of tolerance, drawing instrument.

Existing combined stationery kind is more, as the ZL94216227.7 patent that ruler, protractor, pocket knife, magnifying glass and compasses are combined into one; The CN87206817U patent that integrates functions such as compasses, protractor, ruler and T-square; Integrate the ZL93206498.1 patent of writing function and drawing function etc.These combined stationeries all have characteristic separately, but lack engineer's scale, set square, and structure is desirable not to the utmost, still do not satisfy the needs of people's practical application.

It is one that the purpose of this utility model provides a kind of collection ruler, set square, engineer's scale, protractor, compasses and pencil, and simple and compact for structure, portably use combined stationery easily.

The purpose of this utility model is achieved in that to be connected through the hinge and makes two sections rulers planar both collapsible, can stretch again; Owing to loaded onto propelling pencil and location needle point respectively at two sections ruler positions in opposite directions, therefore, constituted two legs of compasses, have the function of compasses; And hinge fraction has constituted the protractor that can indicate angle; Owing to possessed the function (having angle and limit) of ruler and protractor simultaneously, thereby, the function of set square also possessed; As for engineer's scale, then be that (back side) engraves the scale that has ratio on folding ruler, and have the compasses leg of propelling pencil, can take out again and remove independent use.

The utility model is made simple, and is with low cost, collection ruler, set square, engineer's scale, protractor, and compasses and pencil function are in one, and volume is small and exquisite, portably use conveniently, especially can put into easily in students in middle and primary schools' the writing case.

Fig. 2, Fig. 3 are block diagram.

Fig. 4 is the propelling pencil schematic diagram.

Fig. 5 is a draw key.

By the following examples, in conjunction with the accompanying drawings, the utility model will be further described.

Embodiment:

(referring to Fig. 1,2,3,4,5) will engrave the scale designated size respectively on Fig. 2, the 3 working of plastics inclined-planes, resolution ratio is millimeter (omitting among the figure), inboard, the back side (staggering with the ruler scale) is engraved 1: 250,1: 300 scale respectively, circumferential section among Fig. 2 is engraved 360 ° of scales, resolution ratio is degree, with engraving center line on the boss in the middle of Fig. 3, be used to refer to the protractor scale.Profile propelling pencil as shown in Figure 4, its internal structure is known, controls the length of lead for retractable pencil by the draw key of pushing upper end.Then propelling pencil shown in Figure 4 is plugged on the parts shown in Figure 2 from skewed slot, the bayonet socket place of again two salient points in garden in this part being aimed at Fig. 3 boss press-fits down, make two salient points enter the groove of boss bottom, make it can activity freely, be unlikely again and come off.Fig. 5 spare that will be used for fixing garden rule stitch is at last loaded onto in the skewed slot of Fig. 3 spare.

The utility model can be made into the specification product that varies in size with polystyrene, PVC, lucite and stainless steel material, to satisfy the needs of different object work and study.
