Abstract

The device is a level meter which is used for testing the horizontal position and vertical position of various devices and instrument. The structure is that the circumference of a square frame is respectively provided with 2-4 water level bubbles. The water level bubbles totally have two precision show value regardless from the upper to the lower at any side. Each level water level bubble has graduation precision of both or four faces and the precision is 0.01 mm/m, 0.02 mm/m, 0.05 mm/m and 0.005 mm/m. The both sides frame is provided with two water level bubbles which are vertical to the frame and the roughness does not require too high. The utility model has the advantages of easy use, large measuring scope and high precision, and is suitable for using in various horizontal measurements with high precision.

Description

Combined level meter with multiple division value

The utility model relates to a kind of horizontal survey instrument.

Level meter is mainly used to detect the levelness or the verticality on various device or instrument surface, at present level meter has two kinds of frame or bar formulas, the structure of framework is to lay an air level in the framework bottom of a square, the single face scale, frame is that cast iron is made, framework upper is equipped with a handle, its shortcoming is that an air level only is installed on framework, precision is fixed, function singleness, can only measure the error of a certain precision, can not reach the measurement that can be multi-stage accuracy simultaneously, just need a plurality of level meters if measure multi-stage accuracy, the measurement formality is numerous and diverse, work inconvenience.

For solving above deficiency, the purpose of the utility model is carried from the level meter of the many scale division values of a kind of combined type, can read out in the accuracy value in the different accuracy scope simultaneously.

The technical solution of the utility model is achieved in that around a castiron square framework, an air level all is installed up and down, promptly be that air level is fixed on each side central authorities, two sides or four sides can be installed as required, on each air level, can grind the different scale division value precision at two sides or four sides, framework is vertically stood up, observe from top to bottom from that face two class precision indicating values are all arranged, the precision of every air level can be fourth gear such as 0.01mm/m, 0.05mm/m, 0.02mm/m and 0.0005mm/m.Perpendicular to framework two air levels are housed respectively again in the framework both sides, the air level of placing in framework central authorities is main air level, air level perpendicular to framework is a pair air level, this air level accuracy requirement is not high, it is the single face scale, be generally 0.02mm/m～0.05mm/m, guarantee that just framework front and back verticality gets final product, a framework wherein side bottom has " V " type groove has guaranteed level meter when measuring tubular-shaped structures levelness.

The utility model just is placed with four air levels respectively on four edges of framework, enlarged functions of use, has increased the usable range of level meter, and structural complexity does not increase, can a plurality of scale division values by a level meter, improved testing level, and easy to use.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the level construction schematic diagram according to the many scale division values of combined type that the utility model proposes.

Fig. 2 is many scale division values of combined type level meter vertical view.

Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

This device is made square framework (1) by a cast iron and is formed, at framework (1) two main air levels (2) and (3) are housed respectively up and down, every air level has the two sides scale, no matter (2) and (3) that air level is following, see it all is two air levels from top to bottom, two accuracy value scopes, the precision of (2) and (3) two air levels is respectively 0.01mm/m～0.05mm/m; 0.02mm/m～0.005mm/m; The two payment air levels perpendicular with framework (1) are (4) and (5), and accuracy requirement is not high, has guaranteed the verticality and the levelness of the both sides of spirit-leveling instrument framework (1) during measurement.

Claims

1, a kind of level meter of forming by cast iron framework and glass air level, it is characterized in that around framework (1), can adorning two (2) and (3) or four main air levels, the two payment air levels (4) and (5) perpendicular with framework (1) are housed respectively on the framework of both sides simultaneously, and every main air level can be two sides or four sides scale.Pay air level (4), (5) are the single face scale.

2, by the described level meter of claim 1, it is characterized in that the four sides precision of two main air levels is respectively 0.01mm/m; 0.02mm/m; 0.05mm/m; 0.003mm/m.

3, by the described level meter of claim 1, it is characterized in that the precision of two payment air levels is 0.02mm/m～0.05mm/m, be the plane scale.
