Problems solved by technology

This type of electronic plug gauge has obvious disadvantages: first, the measurement and display processing systems are set separately, and the display processing system is generally a complete set of detection devices, which is large in size and very inconvenient to carry and use; second, due to the electronic plug gauge and display The processing device is connected by a long lead wire, and the uncertainty of the resistance of the connector and the lead wire will inevitably affect the detection accuracy, resulting in unstable display and large errors after measurement; third, since the display device uses 220V AC power supply, when the detection environment lacks When the external power supply is connected, the measuring instrument will not be used

Embodiment Construction

[0025] The present invention is a portable electronic plug gauge, the specific implementation of which is:

[0026] like figure 1 As shown, a portable electronic plug gauge is designed with an integrated structure for measurement and display. A probe 14 is provided at one end of the housing 2. The probe 14 at the front end adopts a double flexible hinge mechanism, and the core components in the sensor 1 (i.e. The magnetic core and the inductance coil) are directly embedded in the double flexible hinge body, the display 4 is embedded outside the casing 2, and the signal processor 3 is arranged in the casing 2, and the sensor 1, the signal processor 3 and the display 4 are sequentially connected in series. The housing 2 is also provided with a HOLD key 12 and a control key 13 .

[0027] In the present invention, the casing 2 can be made of an aluminum casing, which not only effectively shields the external electric field and magnetic field, but also ensures the accuracy of meas...

Abstract

The invention discloses a portable electronic plug gauge, and relates to a measuring instrument. The electronic plug gauge is provided with a shell capable of shielding external signals, one end of the shell is connected with a measuring head, a sensor is arranged in the measuring head body, a signal processor is arranged in the shell, a display is arranged on the shell, an output signal of the sensor is input into the signal processor to be processed, and the processed signal is output and then displayed by the display. Because a measuring and displaying integrated module is designed, the electronic plug gauge has a simple structure and is convenient to carry and use; and because the whole system adopts a transformer circuit and booster circuit module with switching function, on the one hand, the steady working voltage of the whole system is ensured, and on the other hand, the system can enter a power saving mode better under the condition that the gauge is not used for long time so as to furthest improve the service life of the gauge.

Description

technical field [0001] The invention relates to an inner diameter measuring instrument, in particular to a portable electronic plug gauge. Background technique [0002] At present, the existing inductive inner diameter measuring instrument is mainly a set of detection devices with a measuring device cooperating with a display processing system (mostly an electronic column or a measuring electric box). The precise inductive displacement sensor senses the change of the aperture size, and transmits the signal to the display processing device through the lead wire, and displays the processing result. For example, a Chinese patent for a double flexible hinge inductance built-in electronic plug gauge, its application number: 96203363.4 and a Chinese patent for a precision electronic plug gauge, its application number: 200820062450.3. This type of electronic plug gauge has obvious disadvantages: first, the measurement and display processing systems are set separately, and the disp...
