The polygonal level bubble for the leveling instrument comprises a level bubble body with an inner cavity; the level bubble body is prepared from transparent materials; the inner cavity is filled with liquid and air bubbles floating in the liquid; the level bubble body is of a plate shaped structure and equipped with a lower end opening, wherein the lower end opening communicates with the inner cavity and is closed through a hole plugging strip; the inner cavity is of a polygonal structure, comprising a detecting bottom side for detecting, a horizontal side for indicating levelness, a vertical side for indicating the verticality, and an inclined side for indicating an inclination degree; indicating marks are arranged in the middle parts of the horizontal side, the vertical side and the inclined side; an inclination degree detection angle is formed between the vertical side and the inclined side. The polygonal level bubble for the leveling instrument has the advantages of being simple in structure, convenient to process, low in manufacturing cost, simple and convenient to use and operate, widely applied and used, and extensive in application prospect.

Description

Surveyor's staff polygon air level

Technical field

The present invention relates to survey instrument, particularly relate to the surveyor's staff polygon air level for detection level degree, verticality and gradient.

Background technology

Prover or calibrated ruler is usually adopted for when detection level degree, verticality.The calibrated ruler generally used at present generally only has two kinds of measuring abilities of levelness and verticality, and the inclined-plane of 45 degree that cannot realize gradient is particularly general is calibrated.Although had the calibrated ruler possessing levelness, verticality and gradient and detect, it has adopted the mode of combination to detect, and comprises be respectively used to detection level degree, verticality and gradient three independently bubbles.The shortcoming of this surveyor's staff polygon air level is obvious: complex structure, processing and manufacturing is loaded down with trivial details, use is inconvenient, expensive.

Summary of the invention

The shortcoming that the applicant exists for above-mentioned prior art, carries out studying and designing, and provides a kind of surveyor's staff polygon air level, structure is simple, cost is low, easy to use feature that it has.

The technical solution adopted in the present invention is as follows:

A kind of surveyor's staff polygon air level, comprise the body with inner chamber, body is made up of transparent material, the bubble being filled with liquid in its inner chamber and floating in liquid, described body is platy structure, and it is with the lower ending opening with inner space, and described lower ending opening is closed by plug-hole bar; Described inner chamber is with polygonized structure, comprising the detection base for detecting, being used to indicate the horizontal sides of levelness, being used to indicate the vertical edge of vertical bury pipe and being used to indicate the hypotenuse of gradient, gradient detection angle, respectively with cue mark, is with in the middle part of described horizontal sides, vertical edge and hypotenuse between vertical edge and hypotenuse.

Further improvement as technique scheme:

The lower ending opening of described body is with the pyramidal structure expanded outwardly, and described plug-hole bar is with the pyramidal structure coordinated with described opening.

After described plug-hole bar is connected with body fits, the outside surface of plug-hole bar flushes with the lower surface of body.

Described plug-hole bar is with through liquid injection hole, and liquid injection hole is closed by hole plug.

The scope of described gradient detection angle is: 90 °-180 °.

Described gradient detection angle is 135 °.

Described horizontal sides, vertical edge and hypotenuse there is equal length.

Described body is multiangular tubular structure, and its two ends are closed by described plug-hole bar, are filled with liquid in body.

Beneficial effect of the present invention is as follows:

Structure of the present invention is simple, easy to process, low cost of manufacture, use are easy and simple to handle, extensively can promote the use of, have huge application prospect.

Embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

As shown in Figure 1, Figure 2 and Figure 3, the surveyor's staff polygon air level of the present embodiment, comprise the body 1 with inner chamber 11, body 1 is made up of transparent material, as glass, organic glass etc., the bubble 4 being filled with liquid 3 in its inner chamber 11 and floating in liquid 3, body 1 is platy structure, and it is with the lower ending opening be communicated with inner chamber 11, and lower ending opening is closed by plug-hole bar 2, plug-hole bar 2 is with through liquid injection hole 21, and liquid injection hole 21 is closed by hole plug 7; Inner chamber 11 is with polygonized structure, comprising the detection base 110 for detecting, being used to indicate the horizontal sides 111 of levelness, be used to indicate the vertical edge 112 of vertical bury pipe and be used to indicate the hypotenuse 113 of gradient, the middle part of horizontal sides 111, vertical edge 112 and hypotenuse 113 is respectively with cue mark 12, gradient detection angle 5 is with between vertical edge 112 and hypotenuse 113, gradient detection angle 5 is arranged according to the gradient on detected inclined-plane, its scope is 90 °-180 °, because the gradient on detected inclined-plane is mostly 45 °, gradient detection angle 5 is set to 135 °.

As shown in Figure 4, be another structural drawing of the present invention, the difference of itself and Fig. 3 is, the change of the limit number of inner chamber 11, inner chamber 11 is pentagonal configuration.
