Description
Technical field
This utility model relates to a kind of teaching drawing article, particularly a kind of drawing meter ruler.
Background technology
In school, wooden meter ruler is used to the instrument of setting-out picture, particularly at classmate during blackboard newspaper, it is required for wooden ruler and carrys out picture horizontal line lattice, but when setting-out lattice, can only be with one meter of long meter ruler of a hand control, chalk the to be held setting-out of another hands, and easily tilt when drawing long line on blackboard, setting-out is relatively difficult；On the other hand, needing picture certain angle when drawing a picture, then be accomplished by meter ruler and protractor is used in combination, the speed that thus makes to draw a picture is slow, and instrument is more, carries inconvenience.
Summary of the invention
In view of the defect of above-mentioned prior art, the purpose of this utility model is to provide one can fit tightly that blackboard, straight line and angle can be drawn a picture simultaneously and time saving and energy saving meter ruler.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of meter ruler, including meter ruler body, it is provided with Magnet mounting groove in front end, the rear end in described meter ruler body scale face, it is provided with Magnet in described Magnet mounting groove, described Magnet is adhesively fixed with meter ruler body and forms, the centre of described meter ruler body is provided with mercury-balance device, and described mercury-balance device level is embedded in meter ruler body interior；The design of this structure can make being close on blackboard of meter ruler level, and user has only to a hands and just can draw a picture.
Limit further, being provided with protractor in the middle of described meter ruler body, described protractor rotates and is fixed on meter ruler body side, and the design of protractor directly measures angle while can making picture straight line, can rotate protractor to lower section when drawing straight line, the use that unites two into one of two kinds of instruments is more convenient.
Limiting further, be provided with the angulation pointer being fixed on outside protractor, be provided with rotary shaft bottom described angulation pointer in the middle of described meter ruler body, described rotary shaft is connected with meter ruler body and is positioned on the upside of mercury-balance device.
Limiting further, the described angulation pointer anglec of rotation is 180 degree, can easily read data.
Compared with prior art, loaded down with trivial details painting tool is become simple to this utility model by the combination with time saving and energy saving effect, protractor and meter ruler, is difficult to lose；Mercury-balance device can make the long line of picture keep balance, more attractive.
Accompanying drawing explanation
Fig. 1 is the structural representation of meter ruler of the present utility model；
Reference is: 1. Magnet；2. meter ruler body；3. protractor；4. rotary shaft；5. angulation pointer；6. mercury-balance device.
Detailed description of the invention
Technological means, creation characteristic in order to make this utility model realize are easy to understand, and this utility model are expanded on further below in conjunction with specific embodiment.
A kind of meter ruler as shown in Figure 1, including meter ruler body 2, it is provided with Magnet mounting groove in front end, the rear end in described meter ruler body 2 scale face, it is provided with Magnet 1 in described Magnet mounting groove, described Magnet 1 is adhesively fixed with meter ruler body 2 and forms, the centre of described meter ruler body 2 is provided with mercury-balance device 6, and it is internal that described mercury-balance device 6 level is embedded in meter ruler body 2；It is provided with protractor 3 in the middle of described meter ruler body 2, described protractor 3 rotates and is fixed on meter ruler body 2 side, it is provided with, in the middle of described meter ruler body 2, the angulation pointer 5 being fixed on outside protractor 3, it is provided with rotary shaft 4 bottom described angulation pointer 5, rotating 180 deg, described rotary shaft 4 is connected with meter ruler body 2 and is positioned on the upside of mercury-balance device 6.In use meter ruler is positioned on blackboard, regulate meter ruler according to mercury-balance device 6 to be allowed to keep level, protractor 3 can be rotated to lower section during setting-out, needing to measure angle is to be rotated by protractor 3 and meter ruler holding level, regulation angulation pointer 5 just can obtain respective angles, and the design of Magnet 1 can make meter ruler be close to blackboard, and user has only to a hands and just can draw a picture, operation is convenient, time saving and energy saving.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; without departing from the concept of the premise utility; some deformation and improvement can also be made; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.
