Abstract
The invention provides a field angle measurement device, and solves problems that a conventional protractor just can measure an outside angle or an angle on a drawing and cannot measure an angle at a narrow gap effectively. The device comprises an angle measuring disc, wherein the angle measuring disc comprises an angle measuring disc body with measurement scale, and a connection part which is in integrated molding with the angle measuring disc body; and a pointer which is in rotating connection with the connecting part. The device can measure the angle in the narrow gap, and is very high in practicality.
Description
Technical field
The present invention relates to angle measurement tool design field, particularly relate to a kind of subtended angle measurement mechanism.
Background technology
Take measurement of an angle and generally use angulometer, existing angulometer can only measure that be exposed or on drawing angle, angle for depths in slit then can not be measured (slit width≤5mm) effectively, for user brings certain inconvenience.
Summary of the invention
The object of the present invention is to provide a kind of subtended angle measurement mechanism, in order to solve the problem of the angle of the inconvenient measuring slit depths of existing angulometer.
To achieve these goals, the invention provides a kind of subtended angle measurement mechanism, comprising:
Angulation dish, described angulation dish comprise with Measurement scales angulation dish body and with the integrated connecting portion of described angulation dish body;
The pointer be rotatably connected with described connecting portion.
Wherein, described angulation dish body semicircular in shape.
Wherein, described subtended angle measurement mechanism also comprises: the bracket being fixed on the horizontal edge of described angulation dish body semicircular structure.
Wherein, described bracket is fixed on the horizontal edge of described angulation dish body semicircular structure by screw.
Wherein, described screw is arranged at the junction of described connecting portion and described angulation dish body.
Wherein, described connecting portion is vertically connected at the centre position of described angulation dish body horizontal edge.
Wherein, the link position place of described connecting portion and described pointer is provided with rivet; Described pointer is rotatably connected with described connecting portion around described rivet.
The embodiment of the present invention has following beneficial effect:
The subtended angle measurement mechanism of the embodiment of the present invention, can go deep into survey slit inner, measure the size of subtended angle in slit efficiently and easily, there is very high practicality.

Fig. 2 is the measuring principle figure of inventive embodiments.
Description of reference numerals:
1-angulation dish, 11-angulation dish body, 12-connecting portion, 2-bracket, 21-screw, 3-pointer, 31-rivet.
Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with specific embodiment and accompanying drawing.
The embodiment of the present invention solves existing angulometer can not the problem of angle of measuring slit depths, embodiments provides a kind of subtended angle measurement mechanism, as shown in Figure 1, comprising:
Angulation dish 1, angulation dish 1 comprises angulation dish body 11 with Measurement scales and connecting portion 12 integrated with angulation dish body 11;
The pointer 3 be rotatably connected with connecting portion 12.
In a particular embodiment of the present invention, as shown in Figure 1, angulation dish body 11 semicircular in shape structure, and on the curved edge of semicircular structure, be provided with the Measurement scales for taking measurement of an angle; Connecting portion 12 is vertically connected at the centre position of angulation dish body 11 horizontal edge.
The subtended angle measurement mechanism of the embodiment of the present invention, also comprise: the bracket 2 being fixed on the horizontal edge of angulation dish body 11 semicircular structure by screw 21, further, screw 21 is arranged at the junction of connecting portion 12 and angulation dish body 11, and this bracket 2 can play good fixation when taking measurement of an angle.
In a particular embodiment of the present invention, pointer 3 is connected with connecting portion 12 by rivet 31, and further, pointer 3 can rotate around rivet 31.
The subtended angle measurement mechanism of the embodiment of the present invention, can be inserted the inside of institute's measuring angle, and be obtained the number of degrees value of institute's measuring angle by rotary indicator 3, achieve the object can measuring the angle in slit quickly and easily by pointer 3 when taking measurement of an angle.
Illustrate the measuring principle of above-mentioned subtended angle measurement mechanism below.
As shown in Figure 2, assuming that user want measuring slit depths one on subtended angle α.During measurement, first the connecting portion 12 of subtended angle measurement mechanism and pointer 3 are inserted slot angles inside, simultaneously by the outward flange of bracket 2 with survey subtended angle α opposite side fit, prevent the horizontal edge of angulation dish body 11 from entering into surveyed subtended angle inside and being unfavorable for fixation measuring, wherein, as shown in Figure 2, the opposite side of upper subtended angle α is vertical with the common edge of lower subtended angle β with upper subtended angle α; Then rotary indicator 3, makes a hypotenuse of the outer side edges of pointer 3 and upper subtended angle α fit, and now the scale of pointer 3 indication is the number of degrees value of surveyed upper subtended angle α.
The subtended angle measurement mechanism of the embodiment of the present invention, deep enough the surveyed slit of energy is inner, measures the angle of slit depths quickly and easily, has very high practicality.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
