Abstract

The utility model relates to a planemeter comprising a base and two marking rods. The base is a plane structure and the two marking rods keep to be parallel and are respectively and vertically fixed at two ends of the base; the marking rods are made of transparent materials, the surface walls are marked with volumetric scales from top to down and the top parts are connected with top covers by threads. When in use, a user opens the top covers of the marking rods, injects equivalent liquid into the marking rods, leads the liquid in the two marking rods to keep same level under the horizontal state, then covers the top covers for sealing the openings, then places the base on the plane to be measured and observes the change of liquid levels in the two marking rods, thus knowing the inclination or levelness of the plane to be measured. The planemeter has the advantages of simple structure, convenience, practicability, reasonable technique and the like.

Description

Planometer
Technical field
The utility model relates to a kind of survey instrument, especially a kind of planometer.
Background technology
As everyone knows, in people's work or learning process, measure the levelness on some planes through regular meeting.At present, the tool operation of measuring levelness is comparatively loaded down with trivial details, only is fit to professional skilled worker and uses, and can't apply; In addition, present planometer cost is too expensive, and comparatively heavy, brings very big inconvenience for people's work and study.For this reason, we provide a kind of simple, easy to operate new-type planometer of making.
Summary of the invention
The purpose of this utility model provides a kind of planometer, is used to solve common survey instrument cost height, operation inconvenience, is unfavorable for problem such as popularization.
For achieving the above object, the utility model planometer comprises base and two mark posts, and base is a planar structure, and two mark post keeping parallelisms are vertically fixed on the base two ends respectively; Described mark post is that transparent material is made, table wall marking containing mark from bottom to up, and screw top connects top cover.
After adopting said structure, during use, the user opens the top cover of mark post, injection waits quantity of fluid in mark post, make the liquid in two mark posts under horizontality, keep equal height, cover top cover again and seal, then base is placed on the plane to be measured, the liquid level of observing in two mark posts changes, thereby learns the degree of tilt or the levelness on plane to be measured.
Compared with the prior art, the beneficial effects of the utility model are: simple in structure, convenient and practical, technology is reasonable, but the levelness on fast detecting plane is time saving and energy saving.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of the utility model planometer.
Number in the figure: 1 is that base, 2 is that mark post, 3 is that containing mark, 4 is top cover.
Embodiment
As shown in Figure 1, the utility model planometer comprises base 1 and two mark posts 2, and base 1 is a planar structure, and two mark post 2 keeping parallelisms are vertically fixed on base 1 two ends respectively; Described mark post 2 is made for transparent material, table wall marking containing mark from bottom to up 3, and screw top connects top cover 4.
