Abstract
The utility model relates to a tape measure with an angle disk. The tape measure comprises an arc drawing pen which is cooperatively used, wherein a circular tape measure box is internally coiled with a tape measure body with degree scale, a rotating shaft is arranged at the center of the tape measure box, the tape measure box can freely rotate around the rotating shaft, a 360-degree circular dial scale which has the same circle center as that of the tape measure box is fixed at the top end of the rotating shaft, the end of the tape measure body is provided with a pull ring, and the pull ring is fit with the diameter of the arc drawing pen. When the tape measure is used, the circle center of the tape measure box is that of the drawn arc, and the pull ring is outwards pulled, so that the tape measure body can achieve the length of the semidiameter of the arc which needs to be drawn and can be invariably kept, the dial scale can be used for indicating the angle of the drawn arc, the point of the arc drawing pen is penetrated through the pull ring to rotate around the rotating shaft, and the arc with the required semidiameter and angle can be accurately drawn, therefore, the tape measure is very convenient to use.
Description
Technical field
The utility model relates to a kind of measuring tape measure, especially can draw the tape measure of the band angle scale of any radius, arbitrarily angled circular arc.
Background technology
At present, known tape measure all is only to have measurement function, function singleness, but many times draw radius difference, circular arc that angle is different, existing tape measure does not have such function.
The utility model content
In order to overcome the problem of existing tape measure function singleness, the utility model provides a kind of tape measure with angle scale, can accurately finish any radius, the drafting of circular arc at any angle, and is easy to use very convenient.
The technical scheme that its technical matters that solves the utility model adopts is: tape measure is provided with matching used picture arc pen, flexible rule box inner disc in circle is being put the blade that has scale, the flexible rule box center is provided with rotating shaft, flexible rule box can freely rotate around the shaft, the top of rotating shaft is fixed with 360 ° of circular scales with the flexible rule box concentric, the blade end is provided with draw ring, and draw ring matches with the diameter of drawing the arc pen.During use, the flexible rule box center of circle is the center of circle of drawn circular arc, be pulled outwardly draw ring and make blade reach the length of required picture arc radius and remain unchanged, index dial can be used to refer to the angle of drawn circular arc, draws an arc nib and passes draw ring and rotate the circular arc of required radius and angle that can draw around the shaft.
The beneficial effects of the utility model are: can accurately finish any radius, the drafting of circular arc at any angle, and easy to use very convenient.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
1. index dials among the figure, 2. rotating shaft, 3. blade, 4. draw ring, 5. flexible rule box.
Embodiment
In the drawings, tape measure is provided with matching used picture arc pen, flexible rule box 5 inner discs in circle are being put the blade 3 that has scale, flexible rule box 5 centers are provided with rotating shaft 2, flexible rule box 5 can 2 freely rotate around the shaft, the top of rotating shaft 2 is fixed with 360 ° of circular scales 1 with flexible rule box 5 concentrics, and blade 3 ends are provided with draw ring 4, and draw ring 4 matches with the diameter of drawing the arc pen.During use, flexible rule box 5 centers of circle are the center of circle of drawn circular arc, being pulled outwardly draw ring 4 makes blade 3 reach the length of required picture arc radius and remains unchanged, index dial 1 can be used to refer to the angle of drawn circular arc, draws an arc nib and passes the draw ring 42 rotations around the shaft circular arc of required radius and angle that can draw.
