Abstract
The utility model discloses a trisection circular level which comprises a shell body. The shell body comprises a contact surface which is used for being attached to the surface of a to-be-measured object. The shell body is separated equally into three sealed cavities through a transparent cover and a piece of clapboard. Each sealed cavity is filled with liquid and bubbles formed by the liquid, and when all three bubbles are positioned in the center, and the to-be-measured object is shown to be in a horizontal position. The upper surface of the shell body is a spherical surface with a slight altitude difference, and the sealed cavity is of a roundness shape or an oval shape. The transparent cover is made of jaffaite materials, the shell body is made of aluminium alloy or plastics or other light materials, and the liquid is transparent and is water or alcohol. Compared with the prior art, due to the fact that the three bubbles are designed in the trisection circular level, the three bubbles are checked and balanced, so that the trisection circular level is enabled to be leveled fast. Compared with an existing circular level, the trisection circular level is high in leveling accuracy and improves the accuracy of leveling.
Description
Technical field
The utility model relates to a kind of survey instrument, relates in particular to a kind of level meter.
Background technology
The circular bubble of prior art generally is that a bubble is set, and this set is satisfiable for general measurement, but then has certain error for measuring more accurately.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of high-precision three horizontal levels are provided.
For solving this technical matters, the utility model provides a kind of three minutes circular bubbles, comprise housing, this housing comprises that one is used for and the surperficial surface of contact of fitting of object under test, described housing is divided into three airtight cavities by translucent cover and dividing plate, be filled with liquid and formed bubble in each airtight cavity, show that when three bubbles all are in the center institute's object under test is in level.
The upper surface of described housing is the small sphere of the discrepancy in elevation.
Described airtight cavity be shaped as circle or ellipse.
Described translucent cover is that resin material is made.
Described housing is that the light materials such as aluminium alloy or plastics are made.
Described liquid is transparency liquid, and this transparency liquid is water or alcohol.
Beneficial effect: compared with prior art, the utility model is owing to being provided with three bubbles, and tripartite restriction balance can be able to flatten instrument fast, and more existing circular bubble smoothing precision is higher, has improved the precision of leveling.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is A-A diagrammatic cross-section of the present utility model.
Among the figure: 1 housing, 2 surface of contact, 3 translucent covers, 4 dividing plates, 5 airtight cavities, 6 bubbles.
Embodiment
Below in conjunction with drawings and Examples the utility model is done specific descriptions.
Figure 1 shows that the utility model structural representation.
Figure 2 shows that A-A diagrammatic cross-section of the present utility model.
The utility model comprises housing 1, and this housing 1 comprises that one is used for and the surperficial surface of contact 2 of fitting of object under test.
Described housing 1 is divided into three airtight cavities 5 by translucent cover 3 and dividing plate 4.
Be filled with liquid and formed bubble 6 in each airtight cavity 5, show that when three bubbles 6 all are in the center institute's object under test is in level.
The upper surface of described housing 1 is the small sphere of the discrepancy in elevation.
Described airtight cavity 5 be shaped as circle or ellipse.
Described translucent cover 3 is made for resin material.
Described housing 1 is made for light materials such as aluminium alloy or plastics.
Described liquid is transparency liquid, and this transparency liquid is water or alcohol.
The utility model is owing to being provided with three bubbles, and tripartite restriction balance can be able to flatten instrument fast, and more existing circular bubble smoothing precision is higher, has improved the precision of leveling.
The above-mentioned embodiment of the utility model just illustrates, and is not only, all in the utility model scope or the change that is equal in the scope of the present utility model all surrounded by the utility model.
