Description

A kind of Blind Test gap ruler device

Technical field

The utility model relates to engineering construction field of tool, and in particular to a kind of Blind Test gap ruler device.

Background technique

Gap, the gap for much needing to measure are encountered at work, since depth relatively depth or dark are inconvenient to measure Or reading, and Blind Test is needed, after the relative value for determining gap, gap, data are read with measuring scale.As guide vane opening measures When, guide vane opening size first is measured with aperture ruler, then reads data with Steel Ruler；When for another example stator and rotor the air gap measures, Gap size first is measured with stopper ruler, then reads data with vernier caliper.These methods are all more troublesome, and first determine size The method error for reading data afterwards is larger, tends not to meet needs.

Utility model content

The purpose of this utility model is to overcome the shortage of prior art, and provides a kind of Blind Test gap ruler device, solves existing Have when being inconvenient to measure or read due to depth relatively depth or dark, operated using existing measuring tool it is more troublesome, accidentally The larger problem of difference.

The utility model is achieved through the following technical solutions:

A kind of Blind Test gap ruler device, including the first isosceles triangle ruler and the second isosceles triangle ruler, described first Uniformly distributed correspondence markings have the horizontal width size between two waist edges in two waist edges of isosceles triangle ruler, in the first isoceles triangle The high line of shape ruler bottom edge and apex angle is equipped with sliding slot；

The second isosceles triangle ruler bottom edge is equipped with the sliding block matched with sliding slot, the sliding block with the high line of apex angle Installation is matched with sliding slot, the apex angle on the second isosceles triangle ruler bottom edge is identical as the apex angle direction of the first isosceles triangle ruler to be set It sets；

The apex angle of the second isosceles triangle ruler is greater than the apex angle of the first isosceles triangle ruler.

In use, when measurement gap, gap, first by the first isosceles triangle ruler inserted into gap, the side of waist edge and gap It is overlapped, after ruler blocks, then pushes the second isosceles triangle ruler until blocking, then fixed two rulers with hook knob, Ensure that ruler relative position is constant, finally takes out ruler, the first isosceles triangle ruler and the second isosceles triangle ruler intersection, the Corresponding scale is the width in gap on one isosceles triangle ruler.The Blind Test gap ruler can directly measure gap, gap it is big It is small, it is convenient and accurate.

Further, the sliding block be equipped with hook knob, by rotation hook knob by the second isosceles triangle ruler with Position locking between first isosceles triangle ruler.

Further, the apex angle of the first isosceles triangle ruler is 30 °, and the apex angle of the second isosceles triangle ruler is 90°。

Further, the first isosceles triangle ruler with a thickness of 5mm-10mm.

Further, the second isosceles triangle ruler with a thickness of 5mm-10mm.

The utility model compared with prior art, has the following advantages and benefits:

A kind of Blind Test gap ruler device of the utility model, by the different isosceles ruler of two pieces apex angle, one is used to position, One is used to measure, and easy to operate, measurement standard is not limited by space and light, can accurately measure the span in gap.

Detailed description of the invention

Attached drawing described herein is used to provide to further understand the utility model embodiment, constitutes the one of the application Part does not constitute the restriction to the utility model embodiment.In the accompanying drawings:

Fig. 1 is a kind of structural schematic diagram of Blind Test gap ruler device of the utility model；

Label and corresponding parts title in attached drawing:

1- the first isosceles triangle ruler, 2- the second isosceles triangle ruler, 3- sliding slot, 4- sliding block, 5- hook knob.

Specific embodiment

For the purpose of this utility model, technical solution and advantage is more clearly understood, below with reference to embodiment and attached drawing, The utility model is described in further detail, and the exemplary embodiment and its explanation of the utility model are only used for explaining this Utility model is not intended to limit the scope of the present invention.

Embodiment

As shown in Figure 1, a kind of Blind Test gap ruler device of the utility model, including the first isosceles triangle ruler 1 and second etc. Lumbar triangle shape ruler 2, the first isosceles triangle ruler 1 is for measuring, and the second isosceles triangle ruler 2 is used to position, described first etc. Uniformly distributed correspondence markings have the horizontal width size between two waist edges in two waist edges of lumbar triangle shape ruler 1, in the first isoceles triangle The high line of 1 bottom edge of shape ruler and apex angle is equipped with sliding slot 3.

Second isosceles triangle ruler, 2 bottom edge is equipped with the sliding block 4 matched with sliding slot 3 with the high line of apex angle, described Sliding block 4 matches installation, the apex angle side of the apex angle on 2 bottom edge of the second isosceles triangle ruler and the first isosceles triangle ruler 1 with sliding slot 3 To identical setting；The apex angle of the second isosceles triangle ruler 2 is greater than the apex angle of the first isosceles triangle ruler 1.

The sliding block 4 is equipped with hook knob 5, by rotating hook knob 5 for second isosceles triangle ruler 2 and first etc. Position locking between lumbar triangle shape ruler 1.Hook knob 5 and sliding block 4 are threadedly coupled, first isosceles triangle ruler 1 and second etc. When lumbar triangle shape ruler 2 is installed, it is mounted in sliding slot 3 using the sliding block 4 of the second isosceles triangle ruler 2, then by 5 spiral shell of hook knob Line is connected on sliding block 4.
