Abstract

The utility model discloses a multifunctional astrolabe. Two points of equal height needs to be measured in the aspects of buildings, decorations and the like; however, a common measurement tool is a dividing ruler and is often influenced by a series of problems of ground flatness and the like so that the error possibility and the error are great. A common gradienter only can be used for measuring whether the surfaces of objects including grounds and the like are flat or not and cannot measure the size of the inclined angles of the objects so that the points of equal height cannot be measured remotely. The utility model provides the multifunctional astrolabe which can solve the problems of great error possibility and error in the process of measuring the two points of equal height, the size of the inclined angle of the surface of the object cannot be measured, the points of equal height cannot be measured remotely and the like. According to the technical scheme, the multifunctional astrolabe comprises a transverse rod, a laser lamp, an angle scale and a base. Not only can whether the surfaces of the objects including the grounds and the like are flat or not be measured, but also the size of the inclined angle of the surface of the object can be measured; the points of equal height also can be measured remotely.

Description

A kind of multi-functional astrolabe

Technical field:

The utility model relates to a kind of astrolabe, specifically, especially relates to a kind of multi-functional astrolabe.

Background technology:

At aspects such as building, decorations, all can measure two contour points, but general survey instrument is all rule, is often subject to the impact of the series of problems such as ground flat degree, its occur the probability of error and error large.And whether mean level instrument can only be measured the body surfaces such as ground smooth, but cannot measure the size of inclined angle of object, cannot realize telemeasurement contour point.

Summary of the invention:

The purpose of this utility model is to provide a kind of multi-functional astrolabe, can solve that the probability of error appears in above-mentioned measurement two contour points and error is large, the size that cannot measure surficial inclination of body, cannot realize the problems such as telemeasurement contour point.

In order to achieve the above object, the technical solution of the utility model is: a kind of multi-functional astrolabe is partly comprised of cross bar, laser lamp, angle scale, base etc.Wherein, cross bar is comprised of left cross bar, right cross bar and the benchmark cone that is positioned at right cross bar right-hand member.Laser lamp is fixed in the left end of left cross bar.

Angle scale comprises that a boring is with the cylindrical dial of angle index, fly rod and water; The boring place of cylindrical dial contains appropriate water, and fly rod floats on the water surface.Fly rod is that a boring and two ends become circular cone, the pole of middle one-tenth cylinder; The length of fly rod is slightly shorter than the diameter of angle scale.Angle scale is fixed between left cross bar and right cross bar.In cylindrical dial, there are two 0 scales, lay respectively at and left cross bar and right cross bar horizontal alignment part; No matter around 0 scale, still turn counterclockwise clockwise, scale value all evenly increases to 90 degree successively from 0 degree.

Base comprises adjusting bolt, base body and column; Adjusting bolt comprises is with externally threaded pillar and tapped cylindrical setting nut; Column is fixed in base low order end and by hinge-connection mode, is linked in the right-hand member of right cross bar.

The beneficial effects of the utility model are: and mean level instrument (such as: whether smoothly the surveyor's staff that carpenter uses) can only measure the body surfaces such as ground, but cannot measure the size of surficial inclination of body.Whether the utility model not only can be measured the body surfaces such as ground smooth, the most important thing is to measure the size of surficial inclination of body.Particularly whether general measure two contour points are all to equate to determine to ground distance with 2 of ruler measurements, if but ground is not smooth, will affect determining of two contour points so.The principle that the utility model has utilized liquid surface to be always parallel to surface level realizes the accurate measurement of two contour points, has broken away from the impact of the series of problems such as ground flat degree, greatly reduce occur error probability, reduced error.Mean level instrument cannot be realized telemeasurement contour point, and the utility model utilizes laser to solve well this problem, has realized telemeasurement contour point.

In above-mentioned accompanying drawing, the meaning of each numbering is: 1: laser lamp; 2: cross bar; 2-1: left cross bar; 2-2: right cross bar; 2-3: benchmark cone; 3: angle scale; 3-1: cylindrical dial; 3-2: fly rod; 3-3: water; 4: base; 5: column; 6: be with externally threaded pillar; 7: cylindrical setting nut; 8: adjusting bolt; 9: hinge.

Embodiment:

Below in conjunction with accompanying drawing, the utility model is further described.

Refer to Fig. 1～Fig. 3: a kind of multi-functional astrolabe, comprises laser lamp (1), cross bar (2), left cross bar (2-1), right cross bar (2-2), benchmark cone (2-3), angle scale (3), cylindrical dial (3-1), fly rod (3-2), water (3-3), base (4), column (5), is with externally threaded pillar (6), cylindrical setting nut (7), adjusting bolt (8), hinge (9).

Contour point measuring method of the present utility model: cross bar (2) right-hand member benchmark cone (2-3) is aimed to metope one reference point, slewing circle cylindricality setting nut (7) makes cross bar (2) position that is up to the standard, when cross bar (2) is positioned at horizontal level, now at another metope, to irradiate be exactly some the contour point contour with this reference point to laser lamp (1).

Ground flat degree measuring method of the present utility model: the first step, multi-functional astrolabe first carries out horizontal alignment, horizontal alignment method is that multi-functional astrolabe is put in horizontal table top, cross bar (2) left end frame is upper in adjusting bolt (8), when fly rod (3-2) two ends aim at 0 scale cross bar (2) be positioned at horizontal level; If being positioned at horizontal level, cross bar (2) can slewing circle cylindricality setting nut (7) do not make cross bar (2) position that is up to the standard.Second step, is put in body surface by multi-functional astrolabe base (4), if 0 scale is aimed at fly rod (3-2) two ends, exponent surface is smooth without tilting; If fly rod (3-2) two ends misalignment 0 scale exponent surface out-of-flatness has inclination, fly rod (3-2) two ends are exactly the size of surficial inclination of body in the upper angle of aiming at of index dial (3-1) so.
