Abstract

The utility model relates to a digital indicating meter which is used for length measuring tools, which is provided with an indicating needle which can be used for indicating fractional values of millimeters or inches which are measured. A unit position figure disk (decile figure disk which is made by the England) and a decimal and centesimal figure disk (unit's and decimal figure disk which is made by the England) which can rotate with gears are arranged below a bottom disk of the digital indicating meter. Arabic numerals on the figure disk can be displayed at any time on a reading window of the bottom disk of the digital indicating meter. Thus, integer values of millimeters (or inches) and fractional values of millimeters (or inches) which are measured can be read by one time on the digital indicating meter; thus, numbers can be read accurately, and measuring efficiency can be improved. An accompanying diagram of a summary is a front schematic diagram of a metric digital indicating meter.

Description

Digital indicating gauge

The utility model relates to a kind of digital indicating gauge, and it is the indicating gauge of using on a kind of dimensional measuring instrument (as dial caliper), and this indicating gauge can be with the round values of the millimeter measured, shows on dial plate with the form of numeral.

At present, only be carved with the percentage of millimeter on the known dial caliper indicating gauge dial plate.After the measurement, only can read the percentage of millimeter from the dial plate by pointer, the round values of millimeter is then read by the scale on the blade.

The purpose of this utility model provides a kind of indicating gauge, and it can not only read the round values of the millimeter of measurement by pointer on dial plate, also can read the round values of millimeter by the numeral that shows on dial plate.

The purpose of this utility model is to realize like this.It is keeping on the basis of common indicating gauge running part, has increased the running part of units letter disk and ten, hundred figure place letter disks.The drive connection of its dial is: each one of unit numbers output gear and ten, hundred bit digital output gear are housed on the right gear shaft of table, and the gear set of forming separately by this two gear, driving bidentate gear and single-tooth gear respectively rotates, two, single-tooth gear drives the gear and ten of units letter disk again respectively, the gear of hundred figure place letter disks rotates, thereby each relevant dial is rotated respectively, and on the window of meter basecap, demonstrate the millimeter numeral (individual, ten, hundred) of measurement.

After adopting such scheme, just can on dial plate, read measurement millimeter percent value and millimeter round values.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a front description of the present utility model; Fig. 2 is a structural representation of the present utility model; Fig. 3 is transmission of units letter disk and reed location synoptic diagram.

Among Fig. 2: 1, gear 2, ten, hundred figure place letter disks 3, meter basecap 4, dial plate 5, pointer 6, units letter disk 7, gear 8, bidentate gear 9, single-tooth gear 10, ten, hundred bit digital follower gears 11, unit numbers follower gear 12, unit numbers output gear 13, ten, hundred bit digital output gears

Ten, hundred figure place letter disks 2 and gear 1 rotate synchronously for being rigidly connected.Gear 7 and units letter disk 6 also for being rigidly connected, rotate synchronously.

Pointer 5 is 0.02mm along dial plate revolution one lattice, circles to be 2mm.When pointer when 0.5 week (1mm) is changeed in " 0 " position, unit numbers follower gear 11 also changeed for 0.5 week, bidentate gear 8 also changeed for 0.5 week.This moment, bidentate gear 8 handsetting gears 7 changeed a tooth, and units letter disk 6 rotates synchronously, and the numeral that increases progressively (or successively decreasing) 1mm changes.When pointer when 5 weeks (10mm) are changeed in " 0 " position, bidentate gear 8 also changeed for 5 weeks, gear 7 and units letter disk 6 changeed for 1 weeks, then the numeral of units letter disk changes " 0 " into once more by " 0 ".Ten, 2 of hundred figure place letter disks are by ten, hundred bit digital output gears 13, ten, hundred bit digital follower gears 10, single-tooth gear 9, the rotation of gear 1 and increase progressively the variation of (or successively decreasing) 1 numeral (10mm).

The utility model is not subjected to the restriction of embodiment, can be English system as digital indicating gauge yet, and promptly the reading on the table is an inch, and the every lattice of dial plate this moment are 0.001in, and a week is 0.1in, and its dial has decile letter disk and two kinds of individual position, tens letter disks.And for example the number of teeth of bidentate gear 8 can be multiple tooth.Need only guarantee that the gear ratio of the number of teeth of gear 8 and gear 7 is to get final product at 1: 5 this moment, the positioning reed among Fig. 3 shouldn't.

Claims (2)

1, the digital indicating gauge of using on a kind of dimensional measuring instrument, it by gear drive and by pointer on dial plate, illustrate measurement the millimeter percent value, it is characterized in that: a meter basecap that has numerical aperture is arranged below the dial plate, two dial units letter disk and ten, hundred figure place letter disks that can rotate with gear are arranged below the meter basecap.

2, digital indicating gauge according to claim 1 is characterized in that people can read whole numerical value of measurement by pointer, dial.
