Abstract

The utility model relates to an angle measuring instrument. The design is called the universal level instrument. The universal level instrument is provided with a hemispherical level gauge which is composed of a hemispherical surface body provided with the graduation lines, an indication pellet and the liquid filled in an inner cavity, and the thin wall of the hemispherical surface body is transparent. The hemispherical level gauge is sealed and assembled on an extensible base. The universal level instrument can measure and read the sloping angle and the sloping azimuth of the measured plane on one time only. The extensible base makes the design became a portable-type measuring instrument. Thus, the utility model can be used in the equipment installation and the construction work.

Description

Universal level-metre
The utility model relates to a kind of universal horizontal instrument of the usefulness that takes measurement of an angle.
Existing bar shaped and frame level, the sealed glass tubes of belt length bubble that has adopted two orthogonal layouts is as level.One is used for location (being commonly referred to as transversal bubble), and one is used for measuring (being called master level).Before the measurement, must must calculate the scale indicating value just again during reading and can obtain the angle of inclination value by the zero adjuster level of corrections.In fact, institute's angle measurement degree is generally less than 1 ', can't carry out mensuration than wide-angle, function is only limited to the level of corrections degree.When being used for level of corrections and spending, because repetitious measurement often will be done in orientation that can't disposable definite inclination and record the angle of inclination, contingency is stronger.
The design's purpose is to provide level of a kind of usefulness just can single-time measurement and read the angle of inclination and the new-type angle measuring instrument of well azimuth, and can once read any oblique inclination number of degrees in three dimensions.Be called the universal horizontal instrument.
According to the design's universal horizontal instrument, mainly constitute by a dome-type level and base.The dome-type level comprises hemisphere face body, the indication bead that thin-walled that has a scale is transparent and is filled in liquid in the level inner chamber.Base comprises at the bottom of the solid seat of the pedestal of a solid and three extendibles.Pedestal and seat are the connected modes that a kind of precision is slidingly matched at the end.Size, shape at the bottom of three seats are identical.
A recessed garden platform on plane adopts a kind of mode of sealing on the pedestal of the week end of the hemisphere face body of above-mentioned dome-type level and above-mentioned base, and the liquid in the above-mentioned hemisphere face level is leaked anything but.
Accompanying drawing below with reference to one of most preferred embodiment of the design is described in detail the design.
Accompanying drawing 1 is the front elevation of the design's a embodiment.
Accompanying drawing 2 is upward views of the design's a embodiment.Dotted portion has wherein illustrated the position when base launches.
In the accompanying drawing, 1 is the hemisphere face body; 2 are the indication bead; 3 is liquid; 4 is pedestal; 5 is the seat end; 6 is the compass annex; 7 and 8 is two technology through holes.
Be carved with the longitude and latitude line on the outer wall of hemisphere face body 1, resemble terrestrial globe half.The available transparent modified polystyrene single injection-molded of number mark of above-mentioned hemisphere face body 1 and longitude and latitude line thereof, angle orientation.
Indication bead 2 has adopted the little garden of the xylonite system spheroid of a thin-walled hollow.
The liquid 3 that is full of in the inner chamber of hemisphere face body 1 is the mixed liquors that adopt alcohol and ether, and its viscosity is very little, is enough to guarantee liquid 3 flowing freely in inner chamber.
The pedestal 4 of base adopts a Cylinder made of iron, and there is a recessed garden platform on last plane.Two technology small through hole 7 and 8 are arranged between platform plane, garden and bottom surface.
The seat end 5 of base is three steel pieces that are approximately annular.Size, shape, the size of three annular blooms at the seat end 5 are all identical, and its lower plane requires quite level and smooth.
Pass accurate sliding matching mode in principle by garden Zhou Junbu and engage with the lower plane of pedestal 4 at the seat end 5.Accompanying drawing 2 has shown the position of the seat end 5 when drawing in and launch.
Hemisphere face body 1 and pedestal 4 are as shown in Figure 1 after the position close-fitting An Zhuan And sealing, alcohol ether mixed liquor 3 is injected the inner chamber of hemisphere face body 1 by technology through hole 7 or 8, after being full of substantially, promptly two technology through holes are sealed, finished assembling process with epoxy resin.Like this, pedestal 4 top just becomes a dome-type level.
In order to measure the number of degrees of slant angle bearing, so that unified record, present embodiment flat edge garden part on pedestal 4 has increased a compass feature 6.Compass can be used as an annex and splits generally speaking, and this is not the necessary structure of the design.
Aforesaid Universal level-metre provides spirit level of a kind of usefulness with regard to the energy single-time measurement and has read the angle of inclination and the Novel angle measuring instrument of well azimuth. Because its base has adopted the structure of extendible, can become a kind of portable measuring instrument.
Aforesaid Universal level-metre can be used for the in addition mensuration of the levelness of part and building element of machine; Can be used for measure other each interplanar depth of parallelism of part, perpendicularity and gradient; Can be used for measuring the several relevant mutual depth of parallelism, perpendicularity and gradients of other part.
Aforesaid Universal level-metre can assemble at machine, equipment is installed, in the construction as a kind of instrument or portable dam of measuring homework precision.

Claims (3)

1, a kind of angle measuring instrument is called the universal horizontal instrument.Mainly constitute by a level and base.It is characterized in that described level is a transparent hemisphere face body of thin-walled that has scale.Basic full of liquid And has an indication bead littler than liquid specific gravity in the inner chamber of hemisphere face body, base has the seat end and solid pedestal of three extendibles, and a recessed garden platform on plane adopts a kind of mode of sealing to connect on the week end of above-mentioned hemisphere face body and the pedestal of above-mentioned base.
2, by the liquid in the level inner chamber of claim 1 described universal horizontal instrument, be the mixing material of alcohol and ether.
3, by the base of claim 1 described universal horizontal instrument, be that three sizes, shape are identical at the bottom of it, the solid block that is connected with pedestal by accurate sliding matching mode.
