Abstract
The utility model relates to an anti-sliding folding T-square, which comprises a transverse ruler, a vertical rule and a fixing screw. The utility model is characterized in that the transverse rule is longer than the vertical rule; the included angle between the transverse rule and the vertical rule can be changed around the fixing screw as the center; when the rules are rotated to a parallel position, the rules are folded into a straight rule; the lower side of the transverse rule is provided with anti-sliding thorns to enhance the accuracy of using. The utility model has the advantages of small size, flexible use, and multifunction, such as the functions of an angulometer, a balancing rule, an arbitrary angle rule, etc. Besides, the utility model has the advantages of simple structure, easy making, flexible use, convenient portability, etc.
Description
The utility model relates to a kind of anti-skidding folding T-square.
Existing T-square is made up of the protractor on crossfoot, perpendicular chi, the crossfoot and the fixed screw of two chi intersection points, its shortcoming is: volume is dumb greatly, because will select for use in use with the similar long T-square of figure paper size and could satisfy the needs of drawing, its angulation, picture angle be inconvenience all, be unsuitable for the student and use, the ruler dislocation of easily sliding when another is to use, the accuracy of influence drawing, on the drawing board that tilts, put and do not live easy landing when not using.
The purpose of this utility model provides a kind of anti-skidding folding T-square with angulation, picture angle, picture balanced line and functions such as anti-slip, anti-dislocation.
The purpose of this utility model is to realize like this, the crossfoot of this chi on crossfoot is that 180 degree dials are carved with at the center with the screw than perpendicular chi length, being carved with the center line pointer on perpendicular chi, is that the center changes the angle between two chis with the screw, and certain limit of two chis is overlapping when forwarding two chi equilbrium positions to.The utility model also is provided with anti-skidding thorn below crossfoot, to improve use accurate and stable.
The utility model has the advantages that, volume is little, use flexibly, function is many, utilize crossfoot, can the draw angle of various angles of the angle of perpendicular chi, in like manner also can measure the number of degrees at certain angle, with crossfoot or perpendicular chi along certain linear slide, on another chi, just can draw and become the balanced line of any angle with this straight line, two chis are overlapping just can be used as ruler, the utility model also is provided with anti-skidding thorn below crossfoot, spinule is thrust paper during use, in case the ruler dislocation can also prevent the ruler landing on the drawing board that tilts, the utility model is simple in structure in addition in addition, make easily, use flexibly, easy to carry, advantage such as applied widely.
Fig. 1 is the vertical view of anti-skidding folding T-square
Describe specific structural details and the working condition that the utility model proposes in detail below in conjunction with Fig. 1.
This device comprise the 1. perpendicular chi of crossfoot 2. fixed screw 3. the spiral shell nurse 4. dial 5. the 6. anti-skidding thorn of pointer is 7..2. 3. 1. crossfoot link to each other with perpendicular chi by fixed screw, 4. fixes this angle of two chis with the spiral shell nurse.6. dial 5. center line pointer represents angle between two chis.1. and the relative position between the following contactant 7. anti-skidding thorn plays fixedly crossfoot.With 0 degree, 0 point, 180 degree on the dial, the long line in edge of straight line is aimed at the one side at certain angle when using this chi, and the center line that 2. perpendicular chi is gone up is the another side of alignment angle 6., just can read this 6. indicated angle angle of center line on dial.2. 1. the crossfoot that above-mentioned using method adopted should be that transparent material is made with perpendicular chi, 2. the both sides of two chi angles aim at the both sides of institute angulation with the 1. perpendicular chi of crossfoot if not what make when the angulation, on dial, just can read the scale angle angle that 6. center line indicates with transparent material.
As draw the angle of a certain angle, at first crossfoot 1. the high scale dish find the number of degrees that will draw the angle on 5., 3. the center line of 2. going up with perpendicular chi reaches the spiral shell nurse with fixed screw and 4. locks, the angle of this angle of just can drawing along the limit of two chi angles this number of division.
At first on the appropriate location of paper, draw straight line when drawing balanced line, then as required, fix the angle of the 1. perpendicular chi of crossfoot between 2., allow crossfoot 1. or perpendicular chi 2. along linear slide, balanced line with this linear pattern Cheng Suoxu angle just can draw on another chi.
In order to prevent ruler dislocation when the setting-out, this chi has made anti-skidding thorn and has 7. pinned ruler during setting-out, and 7. anti-skidding thorn thrusts paper, makes between chi and the paper to locate, and improves the accuracy of drawing.
Claims (4)
1, a kind of anti-skidding folding T-square, it comprises the fixed screw on crossfoot, perpendicular chi and the two chi intersection points, it is characterized in that: crossfoot is longer than perpendicular chi.
2, anti-skidding folding T-square according to claim 1 is characterized in that: be axle with the fixed screw, crossfoot, perpendicular chi can fold into certain limit position overlapped.
3, anti-skidding folding T-square according to claim 1 is characterized in that: anti-skidding thorn is housed below ruler.
