Description
Technical field
The invention belongs to teaching aid technical field is and in particular to a kind of Multifunction teaching ruler.
Background technology
Religion chi is traditional teaching aid, for assisting teacher to draw, but traditional religion chi, single function, draw required
Need during figure to use using the religion chi of correspondingly-shaped and function with inconvenient to carry it is therefore necessary to design a kind of multifunctional teaching
Tool, realizes multiple mapping needs, meets needed for daily teaching.
Content of the invention
According to above the deficiencies in the prior art, the technical problem to be solved is to propose a kind of multifunction angle square,
Pass through, solve rotating shaft and slide block realizes multiple Plotting Functions, have that picture function is many, feature easy to carry.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is: it is straight that a kind of Multifunction teaching ruler includes first
Chi, the second ruler and the 3rd ruler, described second ruler is provided with slide rail, and described slide rail is provided with slide block, described slide block side
It is provided with fixing buckle, described first ruler is respectively arranged at two ends with first through hole and the second through hole, and described first through hole is provided with hinge
Chain, described hinge is connected with slide block, and described 3rd ruler is respectively arranged at two ends with third through-hole and fourth hole, described third through-hole
Second ruler one end is located at by hinge.
Described first ruler is provided with protractor, and described protractor central point is located at first through hole, described protractor
Zero graduation line and the first parallel, described second through hole is provided with positioner.Described positioner is positioning sucker disk, described
Positioning sucker disk tail end is provided with bearing, and described bearing is fixed on the second through hole.Described second ruler is provided with level indicator, described level
Instrument is cylindrical spirit level.Described 3rd ruler is provided with protractor, and described protractor central point is located at third through-hole, described
The zero graduation line of protractor and the 3rd parallel, described fourth hole is provided with chalk clamping device.Described hinge is damping
Hinge, described hinge is additionally provided with locking device.It is carved with graduation mark on described first ruler, the second ruler and the 3rd ruler, its
Material is rigid plastics.
The medicine have the advantages that this Multifunction teaching ruler can realize the fixed straight line of divider calipers, circle, triangle and parallel lines,
Structure is simple simultaneously, and small volume is convenient for carrying.
Brief description
Below the labelling of the content expressed by this specification accompanying drawing and in figure is briefly described:
Fig. 1 is the structure chart of the Multifunction teaching ruler of the specific embodiment of the present invention.
Wherein, the 1, first ruler, the 2, second ruler, the 3, the 3rd ruler, 4, damp hinge, 5, slide rail, 6, slide block, 7, level
Device, 8, protractor, 9, positioning sucker disk, 10, chalk clamping device.
Specific embodiment
Below against accompanying drawing, by the description to embodiment, for example involved each component of the specific embodiment of the present invention
Shape, construction, the mutual alignment between each several part and annexation, the effect of each several part and operation principle, manufacturing process and
Operate with method etc., is described in further detail, to help those skilled in the art to the inventive concept of the present invention, technology
Scheme has more complete, accurate and deep understanding.
A kind of Multifunction teaching ruler includes the first ruler 1, the second ruler 2 and 3 three sections of the 3rd ruler, is provided with the second ruler
Slide rail 5, described slide rail 5 is provided with slide block 6, and described slide block 6 side is provided with fixing buckle, can pacify and need control slide block 6 in slide rail
Upper fixation or slip, the first ruler 1 one end is connected by damp hinge 4 with slide block 6, and the first ruler is provided with protractor 8, permissible
Rotation makes the first ruler 1 and the second ruler 2 form the angle of fixation, and the other end of the first ruler 1 is provided with positioner, positioning dress
It is set to positioning sucker disk, play the role of positioning on blackboard for absorption.Second ruler 2 and the 3rd ruler 3 two ends are also by hinge even
Connect, the 3rd ruler 3 also has been provided with protractor 8, can rotate and make the first ruler 2 and the second ruler 3 form the angle of fixation,
3rd ruler 3 other end is provided with chalk clamping device, for picture circle.It is additionally provided with locking device on described damp hinge 4, facilitate picture
Angle.It is carved with graduation mark on the first ruler 1, the second ruler 2 and the 3rd ruler 3, for accurate setting-out, the second ruler is provided with
