Description
Technical Field
A multifunctional set square belongs to the field of rulers.
Background
In daily blackboard drawing, drawing is often completed by matching of a protractor and a set square, so that tools are frequently changed, and inconvenience is brought to an operator. Therefore, various tool functions are combined, for example, compasses with protractors (multifunctional compasses, application date: 90, 12, 29, patent number: 90227097.4) are provided, and the gradienter is a hollow circle with the thickness of 1-2 mm and filled with 180-degree liquid. However, the level gauge has the problems that firstly, the liquid volatilization is large at the same temperature due to the large liquid level of the liquid contacting with the gas, so that the 180-degree liquid is reduced, and the measurement accuracy is reduced; secondly, the structural strength of the hollow circle is low, and if the hollow part is easy to deform and damage caused by external pressure, the levelness judgment function is lost; thirdly, the drawing difficulty of the scale marks on the disc surface is high, and the accuracy is low; finally, the thickness of the hollow round cavity is 1-2 mm, the capillary phenomenon is obvious, namely the phenomenon of infiltration or non-infiltration of liquid is obvious, the reading sight is blocked, and the accuracy of measurement is further influenced.
In the utility model 'multipurpose triangle' patent (patent number: 87200869, application date: 1987.12.2), a multipurpose triangle is mentioned, which is characterized in that: the liquid-filled hollow glass is an annular transparent cavity, and liquid and bubbles are filled in the cavity. A similar annular level is also mentioned in the Utility model "improvement of the geological compass inclination measurement" (patent No. 2004100297353, publication No. CN1563893A, published: 2005.1.12). Although the defects of the multifunctional compasses (application date: 90, 12, 29 and the patent number: 90227097.4) in the patent are partially overcome, a new problem exists. The bubble in the cavity has the problem that the moving speed of the bubble is reduced when the bubble is close to the highest point, namely the response speed is reduced.
In order to overcome all the problems, the method is improved on the basis of the prior person, and the problems of high response speed, accurate measurement, easy drawing of scale marks and high drawing precision are solved. The improvement is as follows.
The transparent circular cavity is provided with liquid and bubbles and solid small balls, and the small balls can sink to the lowest point of the liquid under the action of gravity.
The beneficial effects produced are as follows.
(1) After the annular tube is manufactured firstly, the accuracy of scale drawing directly influences the accuracy of the manufactured teaching aid, and the design of the user can exactly improve the accuracy of scale line drawing. The difficulty of drawing the scale marks is obviously reduced because the bubbles and the small balls are always on the same vertical line after the bubbles are stabilized, and the diameters of the manufactured circular rings can be accurately found. Other tick marks may be drawn similarly. In the utility model 'multipurpose triangle' (patent number: 87200869, application date: 1987.12.2), the scale mark is drawn by using a weight line every time, otherwise, the scale mark cannot be drawn, and in the scheme of the utility model, the weight line is always accurately replaced by bubbles and small balls. And the scale marks of a plurality of annular gradienters can be drawn simultaneously.
(2) There are large children as well as small children (e.g., small children) for use of the tool. When lines with the same height are drawn, the big son can see bubbles and also can see small balls; and the small ball can not see the air bubble, so that the small ball plays a role in indicating.
(3) There is sufficient advantage in determining whether a face is level. For example, if the straight edge of the triangular plate is close to the ceiling to determine whether the ceiling is level, and if only bubbles exist in the transparent annular tube, the user may need to raise his head to find the position of the bubbles, which may cause discomfort to the user. If the transparent annular tube is internally provided with the bubbles and the small balls, the user can judge whether the level is horizontal by only looking at the positions of the small balls. In this case, the beads are relatively more comfortable to see than the air bubbles.
(4) The transparent ring tube may disappear or grow during use, so that the accuracy of the bubble indication is remarkably reduced, and the small ball plays an irreplaceable role in the accuracy of measurement.
(5) The bubbles move slowly when approaching the highest point, the response speed of the small balls is high, and the small balls are easy to identify quickly.
The specific technical scheme is as follows.
