Abstract
The utility model relates to a set square with a gradienter, wherein the set square with the gradienter comprises a set square main body; the set square main body is provided with the gradienter along the direction of any side of the set square; the gradienter is a bubbler tube; the bubbler tube is internally filled with ether or alcohol; and the middle part of the bubbler tube is provided with a circular positioning part. When the set square with the gradienter provided by the utility model is used, and when the arrangement direction of the set square is parallel to the horizontal direction, the bubble within the bubbler tube is centrally arranged in the circular positioning part; when the arrangement direction of the set square is not parallel to the horizontal direction, the bubble within the bubbler tube is arranged at other positions, excepting the circular positioning part, in the bubbler tube, so that the straight line drawn out by the user can be prevented from forming a certain angle in relation to the horizontal direction.
Description
Technical field
The utility model relates to a kind of set square, relates in particular to a kind of set square with level meter.
Background technology
When people use set square to draw straight line, do not note slightly the straight line that draws just not be horizontal line but and horizontal direction had the oblique line of certain angle.
The utility model content
When the utility model uses set square to draw straight line at people, do not note slightly the straight line that draws just not be horizontal line but and horizontal direction have certain angle oblique line deficiency, a kind of set square with level meter is provided.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of set square with level meter comprises the set square body, described set square body is along having level meter on the direction of arbitrary three arm of angle, described level meter is a bubbler tube, be full of ether or alcohol in the described bubbler tube, the middle part of described bubbler tube has a circular location division.
The beneficial effects of the utility model are: when using the set square of the utility model band level meter, when direction that is provided with when set square and horizontal direction parallel, bubble in the bubbler tube is centrally placed in the circular location division, when direction that is provided with when set square and horizontal direction are not parallel, bubble in the bubbler tube is positioned at bubbler tube other positions except that circular location division, and straight line and the horizontal direction that can avoid the user to draw have certain angle.
Description of drawings
Fig. 1 is the structural representation of the set square of the utility model band level meter.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
Fig. 1 is the structural representation of the set square of the utility model band level meter.As shown in Figure 1, the set square of described band level meter comprises set square body 1, and described set square body 1 is along having level meter 2 on the direction of arbitrary three arm of angle, and described level meter 2 is a bubbler tube, be full of ether or alcohol in the described bubbler tube, the middle part of described bubbler tube has a circular location division 3.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
