The second paddle that movable slide calliper rule include the first paddle with pointer and intersect with first paddle；The pointer Radial direction along protractor points to scale on protractor, and it can be by being riveted on first paddle in the protractor center of circle Drive and rotated around the center of circle；The outer side edges of the second paddle are tangent with the outer ring of protractor.

It is highly preferred that the fixed slide calliper rule are formed with protractor by monoblock steel plate or transparent plastic sheet cutting, or by two Block steel plate or transparent plastic sheet are spliced.

It is highly preferred that the first paddle for including of the movable slide calliper rule and the second paddle, by two blocks of steel plates or transparent plastic sheet Bar is spliced, or is formed by one block of steel plate or transparent plastic sheet cutting.

It is highly preferred that the protractor, fixed slide calliper rule and movable slide calliper rule, from the corrosion resistant plate that thickness is 1.0～1.5mm Or transparent plastic sheet is made.

This utility model is can be seen that by above-mentioned the technical solution of the utility model to have the following technical effect that：

1st, this utility model makes simple, easy to operate, and cost of manufacture is cheap, it is adaptable to any large, medium and small factory Family.

2nd, this utility model can accurately measure the bending number of degrees that corresponding mold makes bend pipe, be more beneficial for next time Make the adjustment of bend pipe.

3rd, this utility model measurement range is wide, can according to actual needs make the measuring instrument of wide range, for being more than 180 ° of bend pipe angle can easily read its measured value.

Specific embodiment

In order that those skilled in the art more fully understands the technical scheme of the application, below with reference to accompanying drawing to this reality It is described in further details with new.

The orientation such as upper and lower, left and right, front and rear in present specification term is based on position relationship shown in the drawings Set up.Accompanying drawing is different, then corresponding position relationship is also possible to change therewith, therefore can not be interpreted as to protecting model with this The restriction enclosed.

Embodiment one：

This utility model provides a kind of bend pipe angle detection ruler, its structure as shown in Figure 1 to Figure 2, including：It is protractor 1, solid Determine slide calliper rule 2, movable slide calliper rule 3.

Protractor 1 can be semicircle protractor, or circular protractor, is carved with thereon scale.

Fixed slide calliper rule 2 are connected with protractor 1, and the outer side edges of fixed slide calliper rule 2 are tangent with the outer ring of protractor 1.

The fixation slide calliper rule 2 can be formed with protractor 1 by monoblock steel plate or transparent plastic sheet cutting, it is also possible to by two blocks of steel Plate or transparent plastic sheet are spliced.

Movable slide calliper rule 3 include the first paddle 31 with pointer 33 and the second paddle 32.Second paddle 32 and described first Paddle 31 intersects；Pointer 33 can point to the scale on protractor 1 along the radial direction of protractor 1, and it can be by the One paddle 31 drives and is rotated around the center of circle of protractor 1；First paddle 31 can pass through the center of circle that rivet 4 is riveted on protractor 1 And can rotate around the center of circle, it is also possible to the center of circle of protractor 1 is riveted on by bearing pin and can be rotated around the center of circle.The The outer side edges of two paddles 32 are tangent with the outer ring of protractor 1.

Above-mentioned pointer 33 can be right angle as shown in Figure 2, or obtuse angle as shown in Figure 3 etc..

The first paddle 31 and the second paddle 32 that above-mentioned movable slide calliper rule 3 include, can be by two blocks of steel plates or transparent plastic sheet Bar is spliced, it is also possible to formed by one block of steel plate or transparent plastic sheet cutting.

If the radius of protractor 1 is R, bend pipe 5 by the distance of r, the center of circle of the centrage to protractor 1 of amount bend pipe 5 It is a diameter ofRelation between parameters meets：

Above-mentioned protractor 1, fixed slide calliper rule 2, movable slide calliper rule 3, from the corrosion resistant plate making that thickness is 1.0～1.5mm Into.The optimal corrosion resistant plate from thickness for 1.2mm is made.

Operation principle of the present utility model is as shown in Figure 4 and Figure 5：

During work, the fixed slide calliper rule 2 on the one side of protractor 1 and the bus alignment of the straight part of bend pipe 5 first, angulation are fixed on The bus alignment of the circular arc of the outer ring of device 1 and the sweep of bend pipe 5, then rotation activity slide calliper rule 3, make the second of movable slide calliper rule 3 The outer side edges of flat bar 32 are alignd with the bus of the second straight part of bend pipe 5.At this moment, the pointer 33 of movable slide calliper rule 3 can be in angulation Correspondence goes out a scale value on device 1, and the scale value is the angle of bend number of degrees of bend pipe.
