Abstract
The utility model discloses a multifunctional level ruler, which comprises a level straight ruler. The (1) in which a level instrument (2) is arranged. The level instrument (2) is composed of a graduated disk (7) and a heavy bob pointer (6), wherein, the graduated disk (7) is arranged on the level straight ruler (1), and the graduated disk (7) corresponds to the heavy bob pointer (6). The level straight ruler (1) is provided with a direction instrument (3) which is composed of a turning graduated disk (8) and a fixed cross line (9), wherein, the fixed cross line (9) is arranged on the level straight ruler (1), and the fixed cross line (9) corresponds to the turning graduated disk (8). By adopting the structure, a level offset angle and an offset angle in the south and north directions can be directly and respectively read on the level instrument (2) and the direction instrument (3), and the precision can be reached by 1.0 percent. The utility model has the advantages of simple structure, convenient operation, high precision, etc. utility model is extensively suitable for the fields, such as, positioning, lofting, construction, decorating construction, equipment installation, teaching, painting, etc.
Description
One, technical field
The invention relates to a surveyor's staff, but the surveyor's staff of particularly a kind of not only recoverable level but also direction of measurement.
Two, background technology
The surveyor's staff that uses on occasions such as location setting-out, building decoration construction, equipment installation is generally all used bubble formula surveyor's staff at present, judges the flatness of measured object level by observing bubble off scale value, is characterized in simple in structure, easy to use.But also exist the problem of following two aspects, the one, function singleness does not just have it and uses except level of corrections; The 2nd, the flatness of the position judgment level by observing bubble, direct reading, error is big, precision is low.
Three, summary of the invention
In order to overcome existing level chi function singleness, disadvantage that error is big; The invention provides a kind of multifunction level meter that not only can directly survey and draw X deflection angle but also can directly measure the North and South direction deflection angle.The invention solves the technical scheme that its technical matters adopts and comprises horizontal ruler, is provided with level meter in the described horizontal ruler, and level meter is made up of index dial and weight pointer, and index dial is arranged on the horizontal ruler, and index dial is corresponding with the weight pointer.
Described horizontal ruler is provided with direction instrument, and described direction instrument is formed by rotating scale disk and fixed cross line, and the fixed cross line is arranged on the horizontal ruler, and the fixed cross line is corresponding with rotation scale disk.
The side of described horizontal ruler is provided with the side dial window corresponding with level meter.
The upper surface of described horizontal ruler is provided with the high scale window corresponding with level meter.
Described horizontal ruler is made by transparent plastic.
Described horizontal ruler integral body is arranged in endoporus and the metal side tube that horizontal ruler matches, and metal side tube is provided with and index dial, rotate scale disk, side dial window and the corresponding corresponding viewport of high scale window.
Fill with liquid oils in the table chamber of described level meter and direction instrument.
After adopting said structure, by weight pointer on the level meter and the skew of off scale dish, directly the reading horizontal deviation angle can be used as verticality and judges and slope measuring; The angle that North and South direction departs from is directly read in the North and South direction of the rotation scale disk on the direction of passage instrument and the skew of fixed cross line, can be used as protractor and uses; By with the horizontal ruler length that can extend cooperating of metal side tube, accuracy value can reach 1.0%; Have simple and reasonable, easy to use, applied range, precision advantages of higher.
Four, description of drawings
Fig. 1 is the invention structural representation.
Structural representation when Fig. 2 is arranged in the metal side tube for Fig. 1.
Five, embodiment
Shown in Figure 1, be the specific embodiments of a kind of multifunction level meter of the invention, it comprises horizontal ruler 1, one side of horizontal ruler 1 is provided with level meter 2, level meter 2 is made up of index dial 7 and weight pointer 6, and index dial 7 is arranged on the horizontal ruler 1, and index dial 7 is corresponding with weight pointer 6; The opposite side of horizontal ruler 1 is provided with direction instrument 3, and direction instrument 3 is formed by rotating scale disk 8 and fixed cross line 9, and fixed cross line 9 is arranged on the horizontal ruler 1, and fixed cross line 9 is corresponding with rotation scale disk 8; Horizontal ruler 1 is made by transparent plastic.
For the ease of from the side with top eye-level, the side of horizontal ruler 1 and above be respectively equipped with side dial window 4 and the high scale window 5 corresponding with level meter 2.
For the stability of improve the standard instrument 2 and direction instrument 3 readings, fill with liquid oils in the table chamber of described level meter 2 and direction instrument 3.
Shown in Figure 2, for prolonging the length of horizontal ruler 1, improve measuring accuracy and physical strength, horizontal ruler 1 integral body is arranged in endoporus and the metal side tube 10 that horizontal ruler 1 matches, metal side tube 10 is provided with index dial 7, rotates scale disk 8, side dial window 4 and high scale window 5 corresponding corresponding viewports, and metal side tube 10 is provided with scale value.
