Abstract
The utility model relates to a metric and English system indicator used for the linear measurement tool. The metric and English system indicator is a double-pointer indicator. The inner and the outer rings of a dial are marked with two scales of metric and English systems. The measurement is realized via a gear transmission mechanism once, and at the same time two linear measurement numerical values of the metric and English systems are read out. The metric and English system indicator the can be matched with various linear measurement tools such as the caliper so that the tool expense is reduced.
Description
The utility model relates to a kind of metric and English indicating gauge, particularly relates to a kind of metric and English indicating gauge that is applicable to dimensional measuring instrument.
The dial caliper of Xiao Shouing in the market, its indicating gauge are the metric system table or the table made in Great Britain of single variety.Because the indicator of this table is that simple pointer and dial scale are single metric system scale or graduated in English, be subjected to the restriction of its gear train in addition, therefore in the actual measurement process, indicator can only be indicated metric system or a kind of measurement numerical value made in Great Britain, and can not indicate metric and English to measure numerical value for two kinds simultaneously.If will carry out the measurement of two kinds of numerical value of metric and English, then need to be equipped with the needs that two dial calipers can satisfy measurement.So not only having strengthened the instrument expense has, and also brings many inconvenience for the user.
The purpose of this utility model is to overcome in the prior art can only indicate metric system or a kind of this weak point of measurement numerical value made in Great Britain such as the indicating gauge of all lengths survey instruments such as dial caliper, a kind of the simple in structure of dimensional measuring instrument that be applicable to is provided, easy to use and can indicate two kinds of metric and English to measure the indicating gauges of numerical value simultaneously respectively.
This metric and English indicating gauge that the utility model provides, its indicator are two pointers, and the outer ring of dial plate and inner ring are carved with metric system and two kinds of scales made in Great Britain respectively, a pointed metric system scale, and another pointer then points to graduated in English.When measuring after this indicating gauge and the dimensional measuring instrument assembling, two pointers indicate metric system and two kinds of measured values made in Great Britain simultaneously respectively, and its measuring accuracy still meets original accuracy standard separately.
For achieving the above object, the utility model has adopted a cover to be different from the gear drive of former single indicator, one division indicating gauge.This gear train comprises 2 groups of driving wheels and one group of engaged wheel, and each group driving wheel is made of 3 gears, and engaged wheel is made of 2 gears.Its drive connection is that the rotation by two groups of driving wheels drives one group of engaged wheel and rotates, and then drive and to be connected on the engaged wheel and to rotate simultaneously with coaxial Long pointer and the short pointer of engaged wheel, and indicate metric system and two kinds of numerical value made in Great Britain respectively, thereby reach the purpose of this utility model.
Accompanying drawing 1 is the synoptic diagram of former single indicator, one division indicating gauge, and Fig. 2 is a synoptic diagram of the present utility model.
Fig. 3 has provided the cut-open view of the utility model gear train.
Among the figure: (1) gear, (2) gear, (3) short pointer,
(4) gear, (5) gear, (6) gear,
(7) gear, (8) gear, (9) gear,
(10) Long pointer.
Fig. 4 is the synoptic diagram after the utility model assembles with the slide calliper rule with metric and English groove.
Among the figure: (11) tooth bar, (12) blade, (13) chi frame.
The embodiment that provides below in conjunction with accompanying drawing further specifies drive connection of the present utility model and assembling operating position.
Accompanying drawing 3 has provided the drive connection details of the utility model gear drive.Gear (1), (2), (4) and gear (7), (8), (9) constitute 2 groups of driving wheels respectively; Gear (5), (6) then constitute one group of engaged wheel.When gear (2), when rotate (8), drive the gear (1) coaxial, (4) and (7), (9) rotation respectively with it, drive engaged wheel (5), (6) rotation by the rotation that constitutes 2 groups of driving wheels by gear (1), (2), (4) and gear (7), (8), (9) respectively then, the Long pointer (10) and the short pointer (3) that are connected simultaneously on gear (5), (6) also rotate thereupon together, and indicate metric system and two kinds of measurement numerical value made in Great Britain respectively.
In aforesaid gear drive, close the position of each gear: gear (1), (4) and (7), (9) are housed respectively on gear (2), (8) successively, Long pointer (10) and short pointer (3) are housed respectively on gear (5), (6).It is to be noted that the number of touching of gear (2), (8) equates that the number of teeth also equates.
The utility model with the slide calliper rule assemblings operating position with metric and English groove is: when as shown in Figure 2 metric and English indicating gauge was contained on the slide calliper rule of metric and English groove, the tooth bar (11) among the gear among Fig. 3 (2), (8) and Fig. 4 meshed.In measuring process, along with moving of chi frame (13), be arranged in the tooth bar on the blade (12) and gear (2), (8) of indicator gear and carry out relative motion thereupon, the rotation of gear (2), (8) drives the gear (1) coaxial with it, (4), (7), (9) rotation simultaneously respectively.So far, the common one group of engaged wheel of being made up of gear (1), (2), (4) and gear (7), (8), (9) being made up of gear (5), (6) that drives of 2 groups of driving wheels rotates, and then Long pointer (10) and short pointer (3) that drive is connected with gear (5), (6) rotate simultaneously, and indicate metric system and English system to measure numerical value for two kinds respectively, the gauger can read metric system and two kinds of concrete measurement numerical value made in Great Britain simultaneously according to the scale on slide calliper rule and the dial plate.
In the present embodiment, Long pointer (10) is 0.02 millimeter along dial plate outer ring revolution one lattice, and circling is 2 millimeters; Short pointer (3) is 0.001 inch along dial plate inner ring revolution one lattice, and circling is 0.1 inch.
In addition, the utility model is not subjected to the restriction of embodiment, in the utility model scope multiple change can be arranged.Mutual alignment as by transposing gear (1), (5), (7) and gear (4), (6), (9) refers to that English system, short pointer (3) refer to metric system just can realize Long pointer (10), the also corresponding transposing of dial plate Internal and external cycle scale this moment.
The utility model only needs just can read metric system and two kinds of linear measure longimetry numerical value made in Great Britain simultaneously by one-shot measurement, has not only reduced tool expense, and has brought great convenience to the user, and this metric and English indicating gauge can be used for all lengths survey instrument.
