Abstract
Disclosed is a combined scale for engineering. The top end of a horizontal straight scale is connected into the middle of a vertical straight scale by a hinge, the horizontal straight scale and the vertical straight scale are positioned in the same plane, length graduations are disposed on surfaces of both the horizontal straight scale and the vertical straight scale, a slide way is inwards disposed on one side of the horizontal straight scale, two ends of a folding scale are connected into the slide way by rotary shafts, one ends of two scale bodies with identical lengths are connected by a rotary shaft to form the folding scale, and the center of a protractor is sleeved with the folding scale and positioned on a rotary shaft in the slide way. The combined scale for engineering is convenient in use and carrying, reasonable in design and complete in function, and functions of various scales for engineering are integrated.
Description
Technical field
The utility model relates to a kind of drawing instrument.
Background technology
The engineering staff often need draw drawing; In the process of drawing, need to use multiple drawing instrument, for example: T-square, set square, protractor etc., but, several kinds of instruments of needs can take a large amount of desk-top spaces when being used simultaneously; Cause desktop in disorder; And when needs carried, volume was bigger, made troubles to people.
Summary of the invention
The purpose of the utility model has provided a kind of various engineering that integrates and has used chi, complete function, and combined type engineering easy to carry is used chi.
In the utility model; The top hinge of horizontal ruler is connected the middle part of vertical ruler; Both are positioned at same plane and surface both is equipped with the length scale, offer chute in the side direction of horizontal ruler, and the two ends rotating shaft of folding chi is connected in the chute; Said folding chi is connected to form by the rotating shaft at one end of two sections isometric chi bodies, and the center of protractor is connected on folding chi and is positioned in the rotating shaft of chute.
After adopting said structure, when horizontal ruler is vertical with vertical ruler, can be used as T-square and use; Can in chute, pull out folding chi, can slide in chute through rotating shaft in the two ends of folding chi, and two chi folded body places also can adjust angle flexibly; Play the effect of set square, when the protractor bottom was parallel with horizontal ruler, the angle b of horizontal ruler and folding chi one side chi body can measure; The angle a of two chi bodies equals 180-2b in the folding chi; In the time of need carrying, can be placed in the chute, adjust vertical ruler and make it parallel with horizontal ruler with folding chi.
The utility model compared with prior art has following advantage: easy to use, reasonable in design, and integrate various engineering and use chi, complete function, easy to carry.
Description of drawingsFig. 1 is the main TV structure sketch of the utility model.
The specific embodimentIn the main TV structure sketch of the utility model shown in Figure 1; The top hinge of horizontal ruler 1 is connected the middle part of vertical ruler 2; Both are positioned at same plane and surface both is equipped with the length scale, offer chute 3 in the side direction of horizontal ruler 1, and the two ends rotating shaft of folding chi 4 is connected in the chute 3; Said folding chi 4 is connected to form by the rotating shaft at one end of two sections isometric chi bodies, and the center of protractor 5 is connected on folding chi 4 and is positioned in the rotating shaft of chute 3.
