Description

Rotary air-bubble level

Technical field

The present invention relates to measuring appliance fields, particularly, are related to a kind of level meter.

Background technique

During production and living, it is sometimes desirable to carry out the level condition of calibration equipment, instrument by level meter.

A kind of common level meter is by the bubble position of glass liquid in pipe, to judge tested plane currently on the market It is whether horizontal；This level meter it is relatively simple for structure, whether being only capable of determined level, generally can not relatively accurately measure tested Inclined angle between plane and horizontal plane.And though another kind of level meter can accurately measure inclination angle when in use, structure is complicated, Higher cost, volume is larger, is not easy to routine use.

Summary of the invention

In view of the above-mentioned problems, the level meter is by common the purpose of the present invention is to provide a kind of rotary air-bubble level Air-bubble level improve, can relatively accurately measure inclined angle between tested plane and horizontal plane, have simultaneously There is simple structure, keeps cheap cost.

The technical solution adopted by the present invention to solve the technical problems is: the rotary air-bubble level includes pedestal, institute Stating pedestal is elongated cuboid；The positive center of the pedestal is equipped with circular scale, and the circular scale is Angle dial, and its top graduation mark orthogonal with the bottom surface of the pedestal is designated as zero graduation line；Before the circular scale Side is equipped with the pointer that rotate around limbus disk center, and the middle part of the bubbler tube of the pointer and an interior gentle bubble of water content is consolidated Fixed connection, and the axis vertical take-off in the instruction direction and the bubbler tube of the pointer.

Preferably, the center of the bubbler tube is additionally provided with the movement weight rod vertical with the axis of bubbler tube, so that bubbler tube Under the Gravitative Loads of movement weight rod, it is easy to remain to horizontality.

Preferably, the circular scale is transparent, and the reverse side of the pedestal is equipped with and the limbus The circular scale, pointer, bubbler tube can be observed by the convex lens in the convex lens of disk face, and to the round quarter Scale amplifies, consequently facilitating accurately observing scale value.

Preferably, be additionally provided on the pedestal one with the circular scale it is concentric, can be rotated around itself center of circle Angle index turntable；As a result, when inclined surface to be measured is implemented in another inclined surface surface, the phase of two inclined surface is measured In the case where to inclination angle, the inclination angle theta of an inclined surface can be measured first, then rotates the angle index turntable, turn angle index Zero graduation line on disk rotates to the θ Angle Position of the circular scale；Then another inclined surface is measured again, this When, after bubbler tube keeps horizontal, pointer position indicated on the angle index turntable, as two inclined surface Relative inclination.

The beneficial effects of the present invention are: the rotary air-bubble level when in use, is first placed in tested plane； Then bubbler tube is rotated, the bubble in bubbler tube is made to be located at the center of bubbler tube, bubbler tube is horizontal at this time；Due to bubbler tube and refer to Needle is fixedly connected, and pointer can also be rotated with bubbler tube, and pointer and circular scale top zero graduation line angulation be just at this time For the tilt angle for being tested plane.

Detailed description of the invention

Fig. 1 is the schematic diagram of this rotary air-bubble level embodiment one.

Fig. 2 is the structural schematic diagram of this rotary air-bubble level embodiment two.

Fig. 3 is the schematic diagram of this rotary air-bubble level embodiment three.

Specific embodiment

Present invention will be further explained below with reference to the attached drawings and examples:

Embodiment one:

As shown in Figure 1, the rotary air-bubble level includes pedestal 1, the pedestal 1 is elongated cuboid；The base The positive center of seat 1 is equipped with circular scale 2, and the circular scale 2 is angle dial, and its top and the pedestal The orthogonal graduation mark in 1 bottom surface is designated as zero graduation line；It is equipped in front of the circular scale 2 and is rotated around 2 center of circular scale Pointer 3, the pointer 3 is fixedly connected with the middle part of the bubbler tube 4 of the gentle bubble 40 of an interior water content, and the pointer 3 Instruction direction and the bubbler tube 4 axis vertical take-off.

Above-mentioned rotary air-bubble level when in use, is first placed in tested plane；Then bubbler tube 4 is rotated, is made Bubble 40 in bubbler tube 4 is located at the center of bubbler tube 4, and bubbler tube 4 is horizontal at this time；Due to bubbler tube 4 and the fixed company of pointer 3 It connects, pointer 3 can also be rotated with bubbler tube 4, and pointer 3 and 2 top zero graduation line angulation of circular scale are just quilt at this time Survey the tilt angle of plane.

Embodiment two:

Embodiment two as shown in Figure 2 improves on the basis of example 1, and difference is:

The center of the bubbler tube 4 is additionally provided with the movement weight rod 5 vertical with the axis of bubbler tube 4, so that bubbler tube 4 is in movement weight rod 5 Gravitative Loads under, be easy to remain to horizontality, it is not necessary to be manually adjusted.

And the circular scale 2 is transparent, and the reverse side of the pedestal 1 is equipped with the circular scale 2 just Pair convex lens 6 circular scale 2, pointer 3, bubbler tube 4 can be observed by the convex lens 6, and to the circle Dial 2 amplifies, consequently facilitating accurately observing scale value.

Embodiment three:

Embodiment three as shown in Figure 3 improves on the basis of example 1, and difference is: also setting on the pedestal 1 Have one with the circular scale 2 it is concentric, can around itself center of circle rotate angle index turntable 7；As a result, when inclined surface to be measured When being implemented in another inclined surface surface, in the case where the relative inclination that measure two inclined surface, one can be measured first Then the inclination angle theta of inclined surface rotates the angle index turntable 7, the zero graduation line on angle index turntable 7 is made to rotate to the circle The θ Angle Position of dial 2；Then another inclined surface is measured again, at this point, after bubbler tube 4 keeps level, the finger The position indicated on the angle index turntable 7 of needle 3, the relative inclination of as two inclined surface.

The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and Within principle, made any modification, equivalent replacement be should all be included in the protection scope of the present invention.
