Abstract

The utility model relates to a horizontal angle measuring scale, belonging to the technical field of a surveyors level. The measuring scale is composed of a scale casing, a scale shaft, a scale hammer, a pointer, a dial, etc. The scale shaft penetrates through a support bracket arranged in the scale casing, and the scale hammer and the pointer are respectively vertically fixed and connected with the scale shaft. A connecting rod of the scale hammer is perpendicular to the pointer, and the O degree line arranged on the dial is parallel to a measuring surface of the horizontal measuring scale. The utility model is used for horizontal measurement, and can visually reflect the horizontal status of the surface to be measured. The utility model is the ideal horizontal measuring apparatus for engineering construction.

Description

The level angle meter

The utility model relates to the level meter that is used for horizontal survey, belongs to the horizontal measuring instrument technical field.

Existing level meter generally is made up of the wooden body of rectangular parallelepiped and the liquid mark of band bubble, and wooden body bottom surface is straight, is measurement face, and column liquid target axis is parallel with wooden body bottom surface.This level meter can be measured whether level of tested surface, but is difficult to determine the size of the out-of-level degree of tested surface.In the engineering construction, often need the water transfer Pingdu or establish certain gradient, adopt existing level measurement, just very inconvenient.

But the purpose of this utility model is to provide a kind of both measure water flat, can measure the level angle meter of unevenness size again.

The purpose of this utility model is achieved in that the level angle meter is provided with watchcase 1, table hammer 2, table axle 3, pointer 4, index dial 5, measurement face 6, watchcase face 7, support 8, table axle 3 is arranged on connecting rod that Biao Chung 2, pointer 4 on the support 8 be connected Biao Chung with table axle 3 vertical fixing respectively perpendicular to pointer 4, and 0 on the index dial 5 spent line and be parallel to measurement face 6.In order to improve the accuracy of survey measurements, the scale mark inboard on the index dial 5 is provided with reflective mirror circle 9, and during use, the measurement face of level angle meter is positioned on the tested surface.If pointed 0 degree illustrates the tested surface level.If tested surface is not a level, 0 on the pointer of meter and index dial degree line forms certain included angle, readablely goes out angle.

The utility model is rational in infrastructure simple, and easy to manufacture, cost is low, and is easy to use, intuitive measurement results, and the precision height is a horizontal survey instrument desirable in the engineering construction.

Accompanying drawing 1 is a structural representation of the present utility model, 1 watchcase, 2 table hammers, 3 table axles, 5 index dials, 6 measurement faces, 7 watchcase faces, 8 supports, 9 reflective mirror circles among the figure.

Accompanying drawing 2 is a planar structure synoptic diagram of the present utility model, 1 watchcase, 2 table hammers, 3 table axles, 4 pointers, 5 index dials, 6 measurement faces, 7 watchcase faces, 9 reflective mirror circles among the figure.

Below in conjunction with accompanying drawing narration the utility model case study on implementation.

Establish former support 8 in the watchcase 1, table axle 3 is located on the support 8, establishes axle sleeve between table axle 3 and the support 8.Table hammer 2, pointer 4 are connected with table axle vertical fixing respectively, the connecting rod of table hammer 2 is perpendicular to pointer 4, and index dial 5 is fixed on the support 8, and the scale mark inboard of index dial is provided with reflective mirror circle 9, on the index dial 0 degree line is parallel to measurement face 6, and watchcase face 7 adopts glass to be connected with watchcase 1 installation.For adapting to the horizontal survey of longer distance segment, the horizontal survey table can be set up rectangular parallelepiped and help the survey part, during measurement, surveys the part pad below the horizontal survey table helping.
