Abstract
A two-dimensional leveling instrument relates to the technical field of teaching measurement and consists of a cross scale and a hemispheroid. The center of a plane portion of the hemispheroid is fixed at the center of an intersection point of the cross scale, annular scale marks are marked on the spherical surface of the hemispheroid, water or colorful water is filled in the hemispheroid, and after the hemispheroid is sealed, the size of internal air bubbles is exactly identical to that of air bubbles at a fixed point of the hemispheroid. Compared with the prior art, the two-dimensional leveling instrument can directly and accurately obtain the inclined direction of a certain plane (such as a floor tile), can indicate inclined angles via a spherical-surface graduated scale, realizes detection of inclination of slopes from one-dimension to two-dimension, is low in manufacturing cost and convenient in popularization, and is a measuring tool and a teaching aid which can be manufactured quite easily.
Description
Technical field
The utility model relates to a kind of measurement equipment, is the two-dimensional level chi specifically.
Background technology
In teaching, particularly on the science class, needing sometimes needs to show surface level sometimes to the student explain level line; Architectural, need to measure whether level of ground or road surface, and these often all are by explanation, perhaps the master worker utilizes surveyor's staff to carry out, present existing surveyor's staff and grade rod, all be the principle of utilizing weight, once also can only survey the gradient of a certain direction, do not have special two-dimensional measurement instrument.
The utility model content
The purpose of this utility model is at the deficiency that does not have special two-dimensional measurement instrument on the market, and a kind of two-dimensional level chi is provided.
The purpose of this utility model realizes by following technological means: the two-dimensional level chi, to form by right-angled intersection chi and hemisphere, and hemisphere planar section center fixation is at the intersection point center of right-angled intersection chi.
Described two-dimensional level chi is carved with the circular scale line on the hemisphere sphere; Hemisphere is filled with water or colored water, and after the sealing, inner bubble is just consistent with hemispheroidal fixed point bubble place size.
Compared with prior art the utlity model has following tangible advantage: can directly accurately obtain the direction that a certain plane (as the plot brick) tilts, and can represent the angle that tilts by the sphere rule, realize the detection of inclined-plane inclination from the one dimension to the two dimension, cheap, be convenient to promote, be a kind of survey instrument that is highly susceptible to making and teaching aid.
Description of drawings
Fig. 1 is the utility model synoptic diagram.
Fig. 2 is the local enlarged diagram of the utility model.
Wherein: 1. right-angled intersection chi, 2. hemisphere, 3. zero graduation, 4. circular scale line, 5. sphere.
Embodiment
Below in conjunction with description of drawings the utility model is described in further detail:
The use of this two-dimensional level chi is: the right-angled intersection chi 1 of this two-dimensional level chi is placed into a certain plane (as the plot brick), if this planar horizontal, then the bubble in the hemisphere 2 will be at zero graduation 3 places, if this plane of button is out-of-level, then the bubble in the hemisphere 2 will be or not zero graduation 3 places, according to the position of the scale and the bubble place circular scale line 4 of prior mark, know the degree of tilt on this plane, realize tilt detection from the one dimension to the two dimension of inclined-plane.
In a word, the utility model provides the two-dimensional level chi.The above; it only is a part of embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
Claims (2)
1. the two-dimensional level chi is made up of right-angled intersection chi (1) and hemisphere (2), it is characterized in that: hemisphere (2) planar section center fixation is at the intersection point center of right-angled intersection chi (1).
2. two-dimensional level chi according to claim 1 is characterized in that: be carved with circular scale line (4) on hemisphere (2) sphere (5).
