Description

The present invention relates to a technology for installing a safety instruction warning instruction member for an indexed measuring instrument, and particularly relates to a surface screwing structure provided with a warning instruction member capable of sliding and having a function of preventing dropout.

For example, a micro differential pressure gauge and a pressure gauge of existing measuring instruments are provided with an indicator needle in the instrument, the indicator needle rotates according to the pressure, and corresponds to the digital scale plate in the instrument, The numerical value can be visually observed and read. In practice, a safety reference value is set for the measuring device, and a safety mark is added to the measuring device for the convenience of the operator to check whether or not the indicator needle is within the safe range. For example, “a safety indicator structure of a measuring device having a fixing function” in Patent Document 1 is an example.

At present, in the existing measuring equipment to which the safety warning instruction member is added, although the safety warning instruction member has a slide movement adjustment function, a certain drawback still remains. That is, there is a possibility that the safety warning instruction member may fall off. When the safety warning indicating member of the measuring device is dropped and lost, it is completely inconvenient to determine whether or not the reference value is exceeded because the warning indicating function is completely lost.
