Abstract
The utility model discloses a multi-functional angle-drawing ruler. The multi-functional angle-drawing ruler comprises a fixed ruler and a movable ruler. A right arc groove and a left arc groove are respectively formed in a plate surface of the fixed ruler. Cushion blocks are respectively arranged at four corners of the bottom surface of the fixed ruler. Length scales are marked on a right side plate edge of the fixed ruler. Angle scales are marked on a right side groove edge of the left arc groove. A left cylinder, a right cylinder and a block are arranged on the top surface of the movable ruler. The movable ruler, including a front side plate edge thereof marked with length scales, is positioned below the fixed ruler and tightly clings to the bottom surface of the fixed ruler. The left cylinder is inserted into the left arc groove and the right cylinder is inserted into the right arc groove. The multi-functional angle-drawing ruler has following beneficial effects: the multi-functional angle-drawing ruler is simple in structure and convenient in operation and is time-saving and labor-saving; and required triangles are drawn rapidly and accurately.
Description
Technical field
The utility model relates to a kind of leg-of-mutton ruler of drawing.
Background technology
Present teaching ruler tool is independent use mostly, and in the time drawing picture, measurement, accuracy is not high, and error is very large, and can completely is not drawn triangle, can not carry out the measurement of horizontal and vertical directions simultaneously, uses very inconvenient.
Summary of the invention
For solving the problem of above existence, the utility model provides a kind of multifunction picture angle square, its technical scheme of taking is: comprise scale and moving chi, on the plate face of scale, offer respectively right deep-slotted chip breaker and left deep-slotted chip breaker, the size shape of right deep-slotted chip breaker and left deep-slotted chip breaker is identical, and corresponding before and after position, they all have right prominent arc, four jiaos of the bottom surfaces of scale are respectively equipped with cushion block, the right plate of scale is marked with length scale along subscript, the right side groove of left deep-slotted chip breaker is marked with angle index along subscript, on the end face of moving chi, be respectively equipped with left cylinder, right cylinder and fixture block, the front side board of moving chi is marked with length scale along subscript, moving chi is positioned at below scale and is close to the bottom surface of scale, left cylinder is plugged in left deep-slotted chip breaker, right cylinder is plugged in right deep-slotted chip breaker, in the time that left cylinder is positioned at the centre position of left deep-slotted chip breaker, right cylinder is positioned at the centre position of right deep-slotted chip breaker simultaneously, now scale is vertical with moving chi, and the right plate of scale is along being connected to the right-hand member in fixture block.
The utility model utilizes the scale of scale and moving chi, determine the length on two limits of triangle, move formed angle according to moving chi along the groove of scale, determine the angle on above two limits, thereby quick and precisely draw required triangle, also can carry out fast and efficiently the measurement of horizontal and vertical direction, therefore the utlity model has simple in structure simultaneously, easy to operate, time saving and energy saving feature.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail below.
As shown in Figure 1, on the plate face of scale 1, offer respectively right deep-slotted chip breaker 3 and left deep-slotted chip breaker 4, right deep-slotted chip breaker 3 is identical with the size shape of left deep-slotted chip breaker 4, and corresponding before and after position, they all have right prominent arc, four jiaos of the bottom surfaces of scale 1 are respectively equipped with cushion block 8, the right plate of scale 1 is marked with length scale along subscript, the right side groove of left deep-slotted chip breaker 4 is marked with angle index along subscript, on the end face of moving chi 2, be respectively equipped with left cylinder 5, right cylinder 6 and fixture block 7, the front side board of moving chi 2 is marked with length scale along subscript, moving chi 2 is positioned at below scale 1 and is close to the bottom surface of scale 1, left cylinder 5 is plugged in left deep-slotted chip breaker 4, right cylinder 6 is plugged in right deep-slotted chip breaker 3.In the time that left cylinder 5 is positioned at the centre position of left deep-slotted chip breaker 4, right cylinder 6 is positioned at the centre position of right deep-slotted chip breaker 3 simultaneously, and now scale 1 is vertical with moving chi 2, and the right plate of scale 1 is along being connected to the right-hand member in fixture block 7.
In the time drawing triangle, move at left deep-slotted chip breaker 4 and the right deep-slotted chip breaker 3 of scale 1 by left cylinder 5 and right cylinder 6 on moving chi 2 simultaneously, make chi 2 and scale 1 there is certain angle, right side groove by left deep-slotted chip breaker 4 is along the concrete angle number of upper mark, determine the angle number of degrees on triangle both sides, then according to the length scale on the front side board edge of the length scale on the right plate edge of scale 1 and moving chi 2, determine the length on above two limits, and then draw two limits, then connect, finally draw required triangle.Also, on the drawing board that this picture angle square fixed placement can be measured at needs, draw the straight line of measurement level, vertical direction simultaneously.
