Description

Digital Vernier Calipers {Digital vernier calipers}

The present invention relates to a digital vernier calipers, and more particularly to a digital vernier calipers provided with a display unit in front and rear of the vernier caliper mother.

Vernier calipers are widely used in the field with micrometers, for example, as measuring tools for measuring outer diameter, inner diameter or depth. The vernier caliper reads the dimensions measured with a combination of multiple graduated mother and son.

However, in recent years, with the development of the electronics industry, digital vernier calipers having digital display means mounted on the vernier calipers have been used. The digital vernier caliper has an advantage that it is easy to read because the electronic display unit sliding the mother display shows the measured content as a number.

As shown in the drawing, the display unit 12 is provided on the mother 18 of the vernier caliper so as to be slidable. The display unit 12 shows the degree of movement while moving in the longitudinal direction of the mother 18 as the jaws 16a, 16b, 17a, and 17b are opened or contracted.

However, the conventional digital vernier caliper configured as described above is inconvenient to use because the measurement content displayed from the display unit 12 can only be read in one direction of the caliper.

For example, if the conventional digital vernier caliper is held with the left hand and the outer diameter is measured with the jaws 16a and 16b, the display unit 12 faces backward, and the operator cannot immediately read the displayed measured amount. There is inconvenience. After temporarily fixing the jaw of the fixing screw 20, the vernier calipers can only be turned upside down to see the display window 13, but if only the left hand can be used, the fixing screw 20 cannot be tightened.

Similarly, when measuring the inner diameter with the digital vernier caliper, the vernier caliper may need to be turned upside down in order to bring the jaw (17a, 17b) into close contact with the measurement target area. ) Is uncomfortable because it is located backwards. At this time, the vernier caliper may be held by the left hand so that the display unit 12 faces the operator. However, the numbers displayed on the display window 13 are reversed upside down, which may make reading more inconvenient.

The present invention has been made to solve the above problems, the display unit is installed on the front and rear of the mother respectively, so that the display is always directed to the person to measure regardless of the position of the vernier caliper, so that the displayed content can be easily and accurately read. Another object of the present invention is to provide a digital vernier caliper configured to easily read the measured contents even when the caliper is inverted and used so that numbers or letters displayed on one of the display units are displayed upside down.
