Convenient and fast thread plug gauge

Abstract

The invention discloses a convenient threaded plug gauge, comprising: a screw rod and a first measuring part, the first measuring part is set in a conical shape, and the outer diameter of its upper end is larger than the outer diameter of its lower end, the first measuring part The outer surface of the part is provided with multiple layers of external threads, and the pitches of the external threads are the same, and the screw rod is fixedly connected above the first measuring part. Through the above method, although the precision of the portable threaded plug gauge of the present invention is not high, it can quickly know the thread size of the object to be measured, the detection is very convenient, the measurement time is short, the use effect is good, and the use occasions are relatively wide.

Description

technical field [0001] The invention relates to the field of detection equipment, in particular to a convenient threaded plug gauge. Background technique [0002] The thread plug gauge is a tool for measuring the correctness of the internal thread size. The types of this plug gauge can be divided into three types: ordinary coarse thread, fine thread and pipe thread. At this stage, different sizes of internal thread holes need to use different sizes of thread plugs Therefore, in the process of measurement, the operator needs to predict the approximate size first, and then continuously test through different thread plug gauges to finally know the size of the internal thread. The measurement time is long and the measurement efficiency is low. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a convenient threaded plug gauge with very convenient detection, short measurement time and good use effect. [0004] In order to solv...
