Embodiment 1

[0034] see Figure 1 to Figure 7 , a polygonal expandable angle measuring folding ruler, comprising a scale frame 1, a transition ruler 2 and an indicator ruler 3; the scale frame 1 is a frame structure in which three scale scales are movably connected from the end to the end or fixedly connected from the end to the end; One end of the transition ruler 2 is fixedly connected to the scale frame 1, the other end of the transition ruler 2 is hinged to the first end of the indicator ruler 3, and the hinge point is located at the center of the circumscribed circle of the scale frame 1; the second end of the indicator ruler 3 is overlapped On the scale frame 1, the length of the indicator ruler 3 is greater than or equal to the radius of the circumscribed circle of the scale frame 1. Angle values ​​are marked on the scale frame 1 .

[0035] The junction of two adjacent scales of the scale frame 1 is provided with an angle limiting device to limit the angle between two adjacent scal...

Embodiment 2

[0052] see image 3 with Figure 4 The difference between this embodiment and Embodiment 1 is that the scale frame 1 is a regular quadrilateral, the side length of the regular quadrilateral includes two scales connected end to end, and the length of the transition ruler 2 is equal to 1 / 2 of the side length of the regular quadrilateral , one end of the transition ruler 2 is connected at the midpoint of the sides of the regular quadrilateral. Angle limiting devices of 90° and 180° are provided at the junction of two adjacent scales of the scale frame 1 . Such as Figure 4 Shown, described indicator ruler 3 is the telescopic ruler that is made up of the slide bar that chute and chute match.

[0053] This embodiment can also realize angle measurement from 0° to 360°, and the angle measuring ruler is easy to disassemble and carry, and its effect is equivalent to that of Embodiment 1.

Embodiment 3

[0055] see Figure 5 with Image 6 The difference between this embodiment and Embodiment 1 is that the scale frame 1 is a regular hexagon, the length of the transition ruler 2 is equal to the side length of the regular hexagon, and one end of the transition ruler 2 is connected to the apex of the regular hexagon. Such as Figure 5 As shown, the indicator ruler 3 is a two-section scale connected end to end in a straight line. Indicating ruler 3 can also be a rope, such as Image 6 shown. The junction of two adjacent scales of the scale frame 1 is provided with 120° and 180° angle limiting devices; the transition ruler 2 and the junction of the scale frame 1 are provided with a 60° angle limiting device.

[0056] This embodiment can also realize angle measurement from 0° to 360°, and the angle measuring ruler is easy to disassemble and carry, and its effect is equivalent to that of Embodiment 1.

Abstract

The invention provides a polygonal angle-extensible measurement folding rule. The folding rule comprises a graduated frame, a transitional scale and a cuing scale, wherein the graduated frame is of aframe body structure consisting of at least three graduated scales which are movably or fixedly connected end to end; one end of the transitional scale is fixedly connected with the graduated frame, the other end of the transitional scale is in pin-joint with the first end of the cuing scale, and the pin-joint point is located at the center of a circumcircle of the graduated frame; and the secondend of the cuing scale is arranged on the graduated frame in a lap-joint mode, and the length of the cuing scale is greater than or equal to the radius of the circumcircle of the graduated frame. Theinvention further provides an angle measurement method. The method comprises the steps of measurement, reading and the like. The folding rule is simple in structure, materials are convenient to get, and manufacturing cost is low; the graduated frame is formed by sequential pin-joint of the multiple graduated scales, so that the folding rule is convenient to fold and store; the transitional scale and the graduated frame are convenient to disassemble and assemble, so that the folding rule is convenient to carry around; and by setting the graduated scales in different shapes, angle measurement with different precision can be realized, the measurement precision is high, the measurement range is wide, and the angle measurement range from 0 to 360 degrees can be realized.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a measuring folding rule and an angle measuring method for polygons with expandable angles. Background technique [0002] Ordinary folding rules generally have the function of measuring angles, but the measurement accuracy is very small, or other additional components must be added to achieve the function of measuring angles. The main range of existing folding rules for measuring angles is 1-180 degrees. A method of measuring angles with a 3-section folding ruler has average accuracy, and at least two rulers need to be linked during operation; the other method of measuring angles through two-section folding rulers has low accuracy, only 5, 10, 30, 45 Measurements with different degrees of accuracy cannot achieve higher accuracy, and the measurement range is small. [0003] In summary, there is an urgent need for an angle measuring folding rule and an angle measuring method w...
