By adopting the technical scheme, the leveling screws are dispersed, so that the base can be conveniently adjusted.

The utility model discloses further set up to: the extension part horizontally extends outwards from the area right below the electronic balance body.

Through adopting above-mentioned technical scheme, because adjusting screw increases apart from the distance of electronic balance body central authorities, so adjusting screw is under the condition of the same height that rises, and the angle value that the electronic balance body changed reduces, does benefit to the precision that improves the regulation like this.

The utility model discloses further set up to: the included angle between the adjacent extending parts is 90 degrees.

By adopting the technical scheme, after the levelness of one of the extending parts, the levelness of the adjacent extending part is not influenced.

The utility model discloses further set up to: and the lower surface of the bottom plate is provided with a reinforcing rib for improving the rigidity between the extension part and the connecting part.

By adopting the technical scheme, the rigidity of the bottom plate is improved, the bottom plate is not easy to deform, and the original flatness of the bottom plate is kept.

The utility model discloses further set up to: the two electronic gradienters are respectively fixed on the upper surfaces of the two adjacent extending parts.

By adopting the technical scheme, the reading on the electronic level meter can be conveniently and directly read.

The utility model discloses further set up to: the electronic level is arranged in parallel to the extending direction of the extending part.

Through adopting above-mentioned technical scheme, the levelness of its extension of place can direct representation by the electronic level appearance.

To sum up, the utility model discloses a beneficial technological effect does:

1. through the electronic level gauge, the electronic level gauge not only has higher measurement accuracy than a level bubble, but also can display specific readings, so that people can visually know the leveling condition conveniently, and the electronic level gauge reduces the interference of human factors;

2. by arranging the bottom plate, the structure of the base is simplified, and the leveling screws are convenient to mount;

3. through stretching out the regional level of extension portion from the electronic balance body under, because adjusting screw increases apart from the distance of electronic balance body central authorities, so adjusting screw is under the condition of the same height that rises, and the angle value that the electronic balance body changed reduces, does benefit to the precision of improvement regulation like this.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, the utility model discloses an electronic balance, including electronic balance body 1, still include two electronic level 4 that are used for measuring the levelness.

A bottom plate 2 is fixed to the lower surface of the electronic balance body 1. The base plate 2 includes a connecting portion 21 at the center and four protruding portions 22 protruding outward from the connecting portion 21. The angle between adjacent extensions 22 is 90. The bottom plate 2 is also provided with four reinforcing ribs 23, and the reinforcing ribs 23 are positioned on one side of the bottom plate 2 departing from the electronic balance body 1. The reinforcing ribs 23 are located between the connecting portion 21 and the extending portion 22, the reinforcing ribs 23 are connected with the connecting portion 21 and the extending portion 22 in a welding mode, and the four reinforcing ribs 23 correspond to the four extending portions 22 one to one. The reinforcing ribs 23 serve to increase the rigidity of the bottom plate 2, so that the bottom plate 2 is not easily deformed. The connecting part 21 is attached to the lower surface of the electronic balance body 1 and is fixedly connected with the electronic balance body 1 through bolts. The extension parts 22 all extend out horizontally from the area right below the electronic balance body 1, and leveling screws 3 are respectively and vertically installed at the free ends of the extension parts 22.

Two electronic gradienters 4 are respectively located the upper surface of two adjacent extensions 22, and electronic gradienter 4 bonds with extension 22 and links to each other, and electronic gradienter 4 is on a parallel with the direction of extension of its extension 22.

When the leveling screw 3 is adjusted, the displayed indication of the electronic level 4 can directly represent the levelness of the extension 22 on which the indication is located. Whether the plane where the two extending parts 22 are located is horizontal can be directly judged by referring to the levelness of the two adjacent extending parts 22, that is, when the readings of the two electronic levels 4 are both zero, the plane where the two extending parts 22 are located is horizontal, that is, the leveling of the electronic balance body 1 is completed.

In the leveling process, because the included angle between the adjacent extending parts 22 is 90 degrees, when the height of one of the extending parts 22 is adjusted, the adjacent extending part 22 is not affected, namely when the reading of one of the electronic levels 4 is not zero, only two leveling screws 3 in the measuring plane of the electronic level 4 need to be adjusted, and thus the leveling of the electronic balance body 1 can be realized more quickly.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
