Abstract
The utility model discloses a vernier caliper which includes a body, a vernier and two outer measuring claws; the two outer measuring claws are respectively provided with a slender measuring part in opposite direction. The vernier caliper can measure the cavity of diamonds more accurately.
Description
Technical field
The utility model relates to a kind of slide calliper rule, particularly a kind of vernier caliper of measuring diamond.
Background technology
The size of measuring diamond at present is a vernier caliper with the instrument of estimating its weight.This slide calliper rule comprise a fixing engineer's scale or a rule, and vernier can move along this engineer's scale or rule.Be provided with corresponding measuring claw on end of fixing engineer's scale or rule and vernier, wherein, measurement realizes between measuring claw.Measured value is to show by the position of vernier along engineer's scale or rule.This slide calliper rule are known in the art.Those skilled in the art also understand electronic caliper, and the measuring position electricity consumption submode of this electronic caliper shows, and measured value is presented on the display screen that vernier has.
Those skilled in the art can also understand, and this slide calliper rule comprise button or key, by button or key, and the relevant data that the operator can import and measure, these data can be stored in the internal memory of slide calliper rule.
But, adopt above-mentioned vernier caliper when measuring diamond, some potholes on the diamond are difficult to measure, and cause the weight estimation of diamond inaccurate.Because diamond is quite expensive, a little error can cause differing greatly on the price.Therefore, need a kind of vernier caliper of diamond pothole of can accurately measuring of invention to address the above problem.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art part and provides a kind of pothole to diamond to measure vernier caliper accurately.
The purpose of this utility model can realize by following technical measures: a kind of vernier caliper, comprise blade, vernier and two external pelivimetry pawls, and be respectively arranged with the elongated shape measuring piece in opposite directions between described two external pelivimetry pawls.
The utility model vernier caliper can stretch into the elongated shape measuring piece pothole on the diamond owing to be provided with the elongated shape measuring piece in opposite directions respectively between two external pelivimetry pawls, makes that the result who measures is more accurate.
Elongated shape measuring piece and the connected mode of external pelivimetry pawl can be that welding, bolt are connected, the connected mode of habitually practising such as bonding.Elongated shape measuring piece between two external pelivimetry pawls should remain on the precision to guarantee to measure on the same straight line as far as possible; but the conversion that those skilled in the art can carry out according to prior art; for example the elongated shape measuring piece is set to arc or other are irregularly shaped, still is considered as protection domain of the present utility model.
As the preferred implementation of the utility model vernier caliper, described vernier caliper comprises electronic display unit.
As the preferred implementation of the utility model vernier caliper, described elongated shape measuring piece can be spicule or taper thing.
As the preferred implementation of the utility model vernier caliper, described elongated shape measuring piece is a metal elongated shape measuring piece.As the more preferably embodiment of the utility model vernier caliper, described elongated shape measuring piece is the wolfram steel awl.
Description of drawings
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in the accompanying drawing does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of an embodiment of the utility model vernier caliper.
Embodiment
For making the utility model easier to understand, will further set forth specific embodiment of the utility model below.
Embodiment 1
As shown in Figure 1, a kind of vernier caliper 100 of the present utility model comprises blade 10, vernier 20 and two external pelivimetry pawls 30, is respectively arranged with elongated shape measuring piece 32 in opposite directions between described two external pelivimetry pawls 30, and described elongated shape measuring piece 32 is the wolfram steel awl.
In other embodiment of the utility model vernier caliper, vernier caliper can comprise interior measuring claw, pit gauge, electronic display unit etc.; Described elongated shape measuring piece can be spicule or taper thing, and the material that is adopted can be metal, also can be hard plastic etc.
Last institute should be noted that; above embodiment is only in order to the explanation the technical solution of the utility model but not to the restriction of the utility model protection domain; although the utility model has been done detailed description with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
