Referring to fig. 2 and fig. 3, fig. 2 illustrates a state diagram of the notch width measuring device according to an embodiment of the present invention during the process of testing the notch 230 to be tested, and fig. 3 illustrates a structural diagram of the notch width measuring device according to an embodiment of the present invention. An embodiment of the utility model provides a pair of breach width measurement device, breach width measurement device includes: a first measuring member 210 and a second measuring member 220. The first measuring member 210 is slidably engaged with the second measuring member 220, and the first measuring member 210 has an abutting side surface 211 and a first abutting end surface 212 connected to the abutting side surface 211. The abutting side 211 is used for being abutted against one side wall of the gap 230 to be measured. The first abutting end surface 212 is disposed obliquely relative to the abutting side surface 211, and the first abutting end surface 212 is used for abutting against the opening edge 231 of the other opposite side wall of the gap 230 to be tested. The second measuring member 220 has a second abutting end surface 221, and the second abutting end surface 221 is used for abutting against the surface where the opening 231 of the notch 230 to be measured is located.

The notch 230 to be measured is not limited to the indication notch of the switch machine, and may be other types of notches, which are not limited herein.

When the width of the gap 230 to be measured is measured, the first measuring part 210 is inserted into the gap 230 to be measured, so that the abutting side surface 211 is attached to one side wall of the gap 230 to be measured, the first abutting end surface 212 abuts against the opening edge 231 of the other opposite side wall of the gap 230 to be measured, and meanwhile, the second abutting end surface 221 of the second measuring part 220 abuts against the surface of the opening edge 231 of the gap 230 to be measured. Because the included angle a between the first abutting end surface 212 and the abutting side surface 211 is known, the length m of the abutting side surface 211 of the first measuring part 210 entering the gap 230 to be measured can be indirectly obtained according to the sliding amount of the first measuring part 210 relative to the second measuring part 220, and the width of the gap 230 to be measured can be obtained according to a and m through the pythagorean theorem. Thus, even in a narrow operating space, the width n of the notch 230 to be measured can be measured by inserting the end of the first measuring part 210 into the notch 230 to be measured from top to bottom, for example, which facilitates to quickly and accurately measure the width of the notch 230 to be measured.

Referring to fig. 2 and 3, an included angle formed between the first abutting end surface 212 and the abutting side surface 211 is a, and a is 45 °. So, can learn according to the equal principle of two right angle side lengths of isosceles right triangle, the length m that the conflict side 211 of first measuring part 210 enters into the breach 230 that awaits measuring equals with the width n of the breach 230 that awaits measuring, just so obtain the conflict side 211 of first measuring part 210 and enter into the length m that awaits measuring in the breach 230 that awaits measuring and can directly obtain the width n of the breach 230 that awaits measuring, need not to calculate the conversion, efficiency of software testing is higher. Of course, a may also be, for example, 30 °, 40 °, 50 °, 60 °, 70 °, or the like, and the width n of the gap 230 to be measured may also be obtained, where the specific size of a is not limited herein.

In one embodiment, the inner diameter of the blade tube is 7mm to 8mm and the outer diameter of the blade core is 6.5mm to 7.5 mm. Thus, the ruler core in the range can freely slide up and down in the ruler pipe, and can be used for testing the indication notch of the switch machine. It should be noted that, the inner diameter of the ruler tube and the outer diameter of the ruler core are set according to the actual width of the gap 230 to be measured, and it is only necessary to ensure that the outer diameter of the ruler tube is greater than the width of the gap 230 to be measured, and the specific size is not limited.

In one embodiment, the length of the ruler tube is 200mm-210mm, and the length of the ruler core is 180mm-190 mm.

In one embodiment, the end of the blade tube is cut to form the first abutting end surface 212.

In one embodiment, the blade tube is a transparent blade tube and the blade core is a transparent blade core. Thus, the observation to obtain the measurement value of the gap 230 to be measured is facilitated. Of course, the ruler tube is not limited to be a transparent ruler tube, and can also be a semitransparent ruler tube or an opaque ruler tube. The core is also not limited to being a transparent core, but may be a translucent continuous or opaque core.

More specifically, the specific materials of the ruler tube and the ruler core, such as rubber, plastic, metal, etc., all meet the requirements, and are not limited herein.
