Problems solved by technology

The above parameters are measured by vernier calipers. However, when measuring with vernier calipers, it is necessary to adjust the value of vernier calipers. Not only is the operation inconvenient, but also the specific size is not accurate, especially when measuring different sizes, it is necessary to frequently adjust the value of vernier calipers. , affecting the accuracy of the test results

Embodiment Construction

[0023] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0024] Such as figure 1 As shown, the multi-purpose gauge of this embodiment includes an electrode distance detection part 11 , a first distance detection part 31 , a second distance detection part 32 and a flame height detection part 21 . The electrode distance detection unit 11 is used to detect the distance between two electrodes in the tracking test. The first distance detector 31 is used to detect the distance between the nozzle end of the burner and the bottom surface of the sample in the needle flame test. The second distance detector 32 is used to detect the distance between the nozzle end of the burner and the side surface of the sample in the needle flame test. The flame height det...

Abstract

The invention provides a multipurpose gauge which comprises an electrode spacing detection part (11) used for detecting the distance between two electrodes in tracking test, a first distance detection part (31) used for detecting the distance between a nozzle end of a combustor and the bottom surface of a sample in needle flame test, a second distance detection part (32) used for detecting the distance between the nozzle end of the combustor and a side face of the sample in needle flame test, and a flame height detection part (21) used for detecting the height of flame in needle flame test. The multipurpose gauge provided by the invention is more convenient to operate.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a multipurpose gauge. Background technique [0002] At present, electrical safety tests mainly include tracking test, needle flame test and glow wire test. The parameter detection in each test is very important. In the tracking test, it is necessary to measure whether the distance between the two electrodes is 4mm, and whether the angle between the two electrodes is 60 degrees, that is, the distance between each electrode and the sample surface Whether the included angle is 60 degrees; in the needle flame test, it is necessary to measure whether the height of the flame is 12mm, whether the distance between the nozzle end of the burner and the bottom surface of the sample is 8mm, and the distance between the nozzle end of the burner and the side of the sample Whether it is 5mm; in the glow wire test, it is necessary to measure whether the diameter of the glow wire is 4m...
