Abstract
The utility model relates to a teaching aid, in particular to a set square with level gauge, wherein a level gauge is arranged on one right-angle side of the set square, and the direction of the level gauge is parallel to that of the right-angle side. If needing to draw a horizontal line on a blackboard, a user only needs to attach the set square on the blackboard, then adjusts the direction of the set square and lets the bubble of the level gauge on the midpoint, and draws a straight line along the side on the horizontal direction, thereby obtaining a horizontal line. If needing to vertical line, the user only needs to adjust the direction of the set square, lets the bubble of the level gauge on the midpoint, and draws a straight line along the side on the vertical direction, thereby obtaining a vertical line.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of set square with spirit level.
Background technology
When people draw horizontal line or vertical curve with general set square on blackboard, all be to remove picture, draw to such an extent that do not measure up or vertical inadequately through regular meeting like this by estimation.
Summary of the invention
The purpose of this utility model provides a kind of such set square, uses its people just can get level to the line drawing of level without training, and vertical line drawing is got vertically.
The utility model is achieved like this: on a right-angle side of set square, be provided with spirit level, and the direction of spirit level is parallel with the direction of this right-angle side.
Owing to adopt such scheme, the utlity model has attractive in appearance, result of use good, advantage such as easy to operate.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Shown in the figure is structural representation of the present utility model.
Shown in the figure 1 is set square, the 2nd, and spirit level.
The specific embodiment
The utility model can be made like this: a right-angle side of common set square is attached on the horizontal table top, and another right-angle side keeps vertically being screwed spirit level again on this right-angle side of level, and the bubble that makes spirit level is on the mid point of spirit level.As will be when on blackboard, drawing horizontal line, as long as the utility model is attached on the blackboard, adjust bubble that the utility model direction makes spirit level again at mid point, be exactly horizontal line at this moment along drawing straight line on the utility model this edge in the horizontal direction; As will drawing vertical line, as long as adjust bubble that the utility model direction makes spirit level at mid point, at this moment drawing straight line along the utility model on this edge of vertical direction is exactly vertical curve.
