Description
Affiliated technical field:
The utility model relates to a kind of drawing appliance, exactly is a kind of folding utility ruler.
Background technology:
At present existing write or drawing appliance of a great variety, function is different, drawing instrument commonly used has ruler, set square, protractor, compasses etc., but these instrumental functions are single, only can be used for picture straight line, specific angle, circle or take measurement of an angle, if will paint the figure of special angle, just must cooperate use by several instruments, it is cumbersome to map, and the time of cost is more, and carries also very inconvenient.The many drawing instruments of some functions are also arranged on the existing market, but the most complex structure of these instruments is expensive, bulky not portable, and complicated operation. it is bigger to use difficulty, is not suitable for the student and uses.
The utility model content:
In order to address the above problem, the utility model provides a kind of simple in structure, low price, is convenient for carrying, folding utility ruler easy to use.
The technical solution of the utility model is: a kind of folding utility ruler, comprise scale, rotation chi, and the rotation chi is hinged by rotating shaft and scale, and the scale left end is arranged to circular protractor, and the protractor center of circle overlaps with rotating shaft; The rotation chi is provided with a groove radially, and the groove both sides are provided with runway, and runway is nested with slide block is housed, and in the middle of the slide block pen core anchor clamps and dog screw is housed, and upper side is provided with tuning drive gear.
The utility model by rotating the rotation chi, can be made angle at any angle in use, can replace set square fully, and scale rotation chi all can be worked as ruler usefulness, and the circular protractor of scale left end can be worked as protractor and be used.When needs picture circle or circular arc, only need the tuning drive gear of upper end of slide block is moved on the radius scale that needs, with the fixing slide block of dog screw, will rotate chi and rotate needed angle and get final product.When putting into writing case, needs only need the rotation chi forwarded to overlap with scale to get final product.
The utlity model has simple in structure, easy to use, low price, take up space little, be convenient for carrying, advantage that function is many.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described further:
Fig. 1 is the front view of deployed condition of the present utility model,
Fig. 2 is a upward view of the present utility model.
The specific embodiment
Referring to attached Fig. 1 and 2, a kind of folding utility ruler comprises scale 1, rotation chi 2 that transparent plastic is made, and rotation chi 2 is hinged by rotating shaft 3 and scale 1, and scale 1 left end is arranged to circular protractor, and the protractor center of circle overlaps with rotating shaft 3; Rotation chi 2 is provided with a groove radially, and the groove both sides are provided with runway 4, and runway 4 is nested with slide block 5 is housed, and slide block 5 upper sides are provided with tuning drive gear 8, and pen core anchor clamps 7 and dog screw 6 are equipped with in the centre, and pen core anchor clamps 7 are regulated the flexible of pen core by the degree of tightness nut.
When the needs circular arc, only need the tuning drive gear 8 of slide block 5 upper ends is moved on the radius scale that needs, use fixedly slide block 5 of dog screw 6, will rotate the needed angle of chi 2 rotations and get final product; Draw the bowlder step to above-mentioned similar, just behind rotation chi 2 rotations 270 degree, need scale 1 is rotated up 90 degree along the center of circle, continuation will be rotated chi 2 and be revolved and turn 90 degrees then, just obtain complete circle.When putting into writing case, needs only need rotation chi 2 forwarded to overlap with scale 1 to get final product.
