Description

A kind of angle slide calliper rule

Technical field

The present invention relates to measurer technical field, refers specifically to a kind of angle slide calliper rule.

Background technology

Vernier caliper is the common measurer of machinery field, its structure design is mainly used for the length of body structure surface and endoporus is surveyed Amount, for the component thickness or distance measurement of machine internal, vernier caliper is difficult to complete measurement.The measurer species of existing measurer is many More but limitation is larger, only can achievement unit divide the measurement of size, versatility is not strong, therefore, it is necessary to be carried out to the prior art Improve and develop.

The content of the invention

In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of rational in infrastructure, using flexible, can The angle slide calliper rule of measuring angle and component inside size,

To achieve these goals, the present invention uses following technical scheme：

A kind of angle slide calliper rule of the present invention, including two measuring arms, two measuring arms are equipped with the hinge being hinged Chain point；The tail end of one of measuring arm is equipped with the dial being rotatablely connected with it, and dial is equipped with and its one Graduated scale；The tail end of another measuring arm is equipped with pointer.

According to above scheme, the dial and graduated scale are equipped with unified length scale, and the zero point of length scale On the center of circle of dial.

According to above scheme, the distance between the hinge point and measuring arm forward terminal are A, hinge point and measuring arm tail end The distance between be B, then A:B=1：N, N are the integer more than 1, and the length scale is N times of national standard size scale.

According to above scheme, the graduated scale is equipped with national standard size scale.

According to above scheme, angle index that the dial is equipped with, the tail end of one of measuring arm is connected to quarter On the center of circle of scale.

According to above scheme, the hinge point is equipped with tightening nut.

The present invention has the beneficial effect that：The present invention is rational in infrastructure, is realized by the measuring arm of scissor structure and gos deep into inside configuration Measuring part size, measured value amplifies integral multiple accurately to show numerical value, while can have angular surveying, compasses, parallel lines etc. concurrently Draw application, have the advantages that it is flexible and convenient to use, have a wide range of application.

Embodiment

Technical scheme is illustrated with embodiment below in conjunction with the accompanying drawings.

As shown in Figure 1, a kind of angle slide calliper rule of the present invention, including two measuring arms 1, two measuring arms 1 are equipped with The hinge point 11 being hinged；The tail end of one of measuring arm 1 is equipped with the dial 2 being rotatablely connected with it, dial 2 It is equipped with the graduated scale 3 integral with it；The tail end of another measuring arm 1 is equipped with pointer 12；1 front end of measuring arm is survey Away from end, the scissor structure of two compositions of measuring arms 1 can go deep into inside parts and measure, and measured value passes through two 1 tails of measuring arm End spacing is shown on dial 2 and graduated scale 3, while the measuring arm 1 on dial 2 forms angle measuring tool with graduated scale 3, real Measurer generalization is showed, easy to use and flexible, has a wide range of application.

The dial 2 and graduated scale 3 are equipped with unified length scale 31, and the zero point of length scale 31 is arranged on scale On the center of circle of disk 2, the length scale 31 on the dial 2 includes negative value range, the ranging of one of measuring arm 1 End, hinge point 11 and tail end tie point are on same straight line, ranging end, hinge point 11 and the tail end of another measuring arm 1 refer to Pin 12 is on same straight line, and when measuring reduced size, the tail end of two measuring arms 1 can surmount closing point, it is therefore desirable to negative Value range is supplemented to measure small size workpiece.

The distance between the hinge point 11 and 1 forward terminal of measuring arm are A, between 1 tail end of hinge point 11 and measuring arm Distance is B, then A:B=1：N, N are the integer more than 1, and the length scale 31 is N times of national standard size scale 32；It is described whole Measured value can be amplified by the 1 brachium ratio of measuring arm of several times, in order to accurate after by length scale 31, measured value is amplified Show reading.

The graduated scale 3 is equipped with national standard size scale 32, and graduated scale 3 can have the function of ruler measurement concurrently.

The angle index 21 that the dial 2 is equipped with, the tail end of one of measuring arm 1 are connected to the circle of dial 2 In the heart, the measuring arm 1 on the dial 2 forms angle clip with graduated scale 3, so as to fulfill the multifunction of measurer, expands Application range.

The hinge point 11 is equipped with tightening nut, and the hinge point 11 that tightening nut is adjusted in two measuring arms 1 is elastic Spend, compasses, which can be achieved, after fixed between measuring arm 1 draws circle or the operation that draws parallel lines.

The above is only the better embodiment of the present invention, therefore all constructions according to described in present patent application scope, The equivalent change or modification that feature and principle are done, is included in the range of present patent application.
