Abstract

The utility model discloses an obliqueness measuring instrument, which is used for measuring levelness, verticality or obliqueness. The obliqueness measuring instrument comprises a measuring scale (10) of an oblong shape, wherein the upper surface of the measuring scale (10) is horizontally and longitudinally provided with a horizontal pipe II (8); a side face of the measuring scale is provided with a vertically arranged horizontal pipe I (7); both the horizontal pipe I (7) and the horizontal pipe II (8) are provided with bubbles and alignment lines; the two ends of the measuring scale (10) are provided with adjusting handles (4, 4'), variable resistors (2, 2'), electron displacement transducers (1, 1') and display screens (3, 3') respectively; the variable resistor (2) is uniformly distributed in a measuring region of the adjusting handle (4); the distance for backward and forward movement of the adjusting handle (4) is determined by sensing resistance value of the variable resistor (2) through the electron displacement transducer (1); and the distance is displayed by the display screen (3).

Description

The slopes test appearance

Technical field

The utility model relates to a kind of survey instrument, specifically is a kind of slopes test instrument.

Background technology

The instrument of existing measurement levelness, verticality, gradient mostly can only qualitatively be estimated, and is difficult to obtain quantitative, accurate result, and can access the instrument of accurate numerical value, and general complex structure involves great expense, and practicality is not strong.

The utility model content

The utility model technical matters to be solved provides a kind of slopes test appearance, is used for measuring levelness, verticality or gradient.

For solving the problems of the technologies described above; The utility model adopts the basic design of technical scheme to be: a kind of slopes test appearance, comprise the mensuration chi of rectangular shape, and measure the horizontal tube I that the chi upper surface has level, vertically installs; Measure ulnar surface vertically arranged horizontal tube II is arranged; Said horizontal tube I, horizontal tube II all have bubble and alignment line, measure the chi two ends and are respectively equipped with adjusting handle, variable resistor, electronic displacement sensor and display screen, and variable resistor is distributed in the adjusting handle measured zone; Electronic displacement sensor is confirmed the distance that adjusting handle moves forward and backward through the variation of perception variable resistor resistance, and should distance by the display screen demonstration.

Preferably, said horizontal tube I, horizontal tube II are installed in and measure the chi middle part.

The beneficial effect of the utility model is, moves radially the difference of distance through two adjusting handles, can obtain levelness, verticality or the gradient of testee, and the numerical value accuracy is high, and the utility model is simple in structure, cheap, easy to use.

Embodiment

Shown in accompanying drawing; The utility model comprises the mensuration chi 10 of rectangular shape; Measure the horizontal tube II 8 that chi 10 upper surface interpositions are equipped with level, vertically install; Measure chi 10 side interpositions and be equipped with vertically arranged horizontal tube I 7; Bubble I 5 and alignment line I 6 are set on the horizontal tube I 7, bubble II 9, alignment line II 6 ' are set on the horizontal tube II 8, measure chi 10 two ends adjusting handle I 4, electronic displacement sensor I 1, variable resistor I 2, display screen I 3 and adjusting handle II 4 ', electronic displacement sensor II 1 ', variable resistor II 2 ', display screen II 3 ' are set respectively; Variable resistor I 2 is distributed in adjusting handle I 4 measured zone; Electronic displacement sensor I1 confirms the distance that adjusting handle I 4 moves forward and backward through the variation of perception variable resistor I 2 resistances, and shows that by display screen I 3 should distance, and the working mechanism of variable resistor II 2 ', electronic displacement sensor II 1 ', display screen II 3 ' is identical with afore-mentioned.

During use, the utility model is affixed on testee, turn adjusting handle I 4 and adjusting handle II 4 '; Make horizontal tube II 8 (is example to measure levelness) go up bubble II 9 and just in time be in 6 ' time of alignment line II; Confirm that two adjusting handles move radially the difference of distance, i.e. the difference of reading of display screen I 3, display screen II 3 ' can obtain the levelness or the gradient of testee; If the difference of reading of two display screens is a; The distance of two adjusting handles is b, and the gradient of testee is β, then tan β=a/b; If need know the testee verticality, then be as the criterion with horizontal tube I7, other situation are identical, repeat no more.
