Abstract

The utility model discloses an outside micrometer, and particularly to an outside micrometer capable of measuring the distance between opposite angles of a blade with an angle. The technical problem to be solved is that an outside micrometer is hard to fix, and measurement is difficult when the outside micrometer is used for measuring the distance between opposite angles of a polygonal product. The outside micrometer includes a measuring anvil and a micrometer screw which are respectively fixed at opposite sides of a U-shaped support, and at least one end of the measuring anvil or the micrometer screw is provided with an angle groove. The outside micrometer is simple in structure and convenient to operate, and can conveniently measure the distance between opposite angles of a polygonal product, such as a triangle product, a quadrangle product and the like.

Description

A kind of outside micrometer

Technical field

The utility model relates to a kind of survey instrument, is specifically related to a kind of outside micrometer that can measure with the diagonal-size of angle blade.

Background technology

Outside micrometer is the length measuring instrument more accurate than vernier caliper, it is current inside plants quality conventional survey instrument while checking, conventional external diameter gauge can be used for the thickness, external diameter, length and width etc. of measurement rules object, but meet the polygonal product needed such as triangle, four distortion while measuring its diagonal-size, owing to being difficult to fix, be difficult for measuring.

Summary of the invention

The technical problems to be solved in the utility model is, while adopting outside micrometer to measure the diagonal-size of polygon product, to be difficult to fix, and is difficult for measuring, and a kind of outside micrometer that is convenient for measuring the diagonal-size of polygon product is provided.

For achieving the above object, the utility model adopts following technical proposals: a kind of outside micrometer, comprise gage button and micrometric screw, and gage button and micrometric screw are separately fixed at the opposite side of U-shaped support, and described micrometric screw and gage button at least one end are provided with angle-shaped groove.

Described micrometric screw and gage button two ends are equipped with angle-shaped groove.

On described micrometric screw one end, establish on angle-shaped groove or gage button one end and establish angle-shaped groove.

Described angle-shaped groove is that angle is 20 ° to 160 °.

Adopt the utility model of said structure, simple in structure, easy to operate, can measure easily the diagonal-size of the polygon products such as triangle, quadrilateral.

Accompanying drawing explanation

Fig. 1 all establishes the structural representation of angle-shaped groove on gage button and micrometric screw.

Fig. 2 is the structural representation of establishing angle-shaped groove on gage button.

Fig. 3 is the structural representation of establishing angle-shaped groove on micrometric screw.

Embodiment

As shown in Figure 1, Figure 2 and Figure 3, the utility model comprises gage button 5 and micrometric screw 1, and gage button 5 and micrometric screw 1 are separately fixed at the opposite side of U-shaped support 7, and described micrometric screw 1 and gage button 5 at least one end are provided with angle-shaped groove 2.

Described micrometric screw 1 and gage button 5 two ends are equipped with angle-shaped groove 2.

On described micrometric screw 1 one end, establish on angle-shaped groove 2 or gage button 5 one end and establish angle-shaped groove 2.

Described angle-shaped groove 2 is that angle is 20 ° to 160 °.

Described angle-shaped groove 2 can be made the triangle of different angles according to the shape of required measurement products, also can make other shape, as trapezoidal, circular arc etc.

During use, according to the shape of product, select gage button 5 and the micrometric screw 1 with suitable angular shape groove, product is put into angle-shaped groove 2 clampings and measure.
