Description

Portable multi-function gem and jade assessor

The utility model relates to a kind of evaluation equipment, a kind of specifically portable multi-function gem and jade assessor.

Along with development of times, the change of people's consumption viewpoint, increasing people like wearing and collect gem and jade ornaments and handicraft, but the gem and jade assessor that Gong the consumers in general that also do not have a kind of convenience to popularize at present on the market use, and gem and jade goods in the market are to mix the genuine with the fictitious, and make consumer's interests be difficult to be protected.

The purpose of this utility model is to provide a kind of professional person that both had been fit to, again can be for the portable multi-function gem and jade assessor of ordinary consumer use.

Know from crystal optics, any heterogeneous body crystal, under cross-polarized light, rotate 360 ° will occur four times from deceive become clear or from the dark that becomes clear phenomenon--this calls it " delustring ", with when the optical axis of crystal is parallel with radiation direction, crystal is complete black (promptly can't see observing object on last polaroid).The utility model is just according to this principle design.

Specific embodiments of the present utility model is: a kind of portable multi-function gem and jade assessor, this assessor is made up of hollow shape cylinder, sample secured adjusted device and adjustment spoon, unglazed black coating or black cloth are arranged in this cylinder, this cylinder is divided into dismountable three sections: go up polarisation cylinder, polarisation cylinder and can make the middle cylinder of 360 ° of rotations down, polaroid of last polarisation cylinder top edge, polaroid of following polarisation cylinder bottom edge, the polarization direction of these two polaroids is vertical; The middle part of middle cylinder respectively has one to wearing circular hole along diametric two walls, an aperture is arranged less than to wearing the upright opening of circular hole on to the wall of wearing the Circularhole diameter vertical direction, and the outer pit aperture in three holes indicates 360 ° of scales; Sample secured adjusted device is made up of rotary handle and sample handgrip, and rotary handle is positioned at any a pair of perforation mouth, and the sample handgrip is arranged in cylinder; Rotary handle is cupped one hand in the other before the chest with the moon shape that links to each other with the handle plate washer by the handle plate washer and is formed, the baffle plate of handle is rounded, diameter greater than on the middle cylinder to wearing circular hole, the moon shape of the part that links to each other with the handle baffle plate is cupped one hand in the other before the chest the diameter of part less than the diameter to perforation on the middle cylinder; The sample handgrip by gripper and fixedly the stationary pipes of gripper form, there is an annular groove stationary pipes middle part, two symmetrical double wedges are arranged at the bottom.The adjustment spoon is made up of the circular baffle plate on a hollow tubular and the hollow tubular, and the diameter of this hollow cylinder is less than the upright opening aperture, the hollow tubular front end have one with sample handgrip stationary pipes on the corresponding groove of double wedge, the diameter of this circular baffle plate is greater than the upright opening aperture.

The fixed agraffe that last polarisation cylinder, following polarisation cylinder appropriate section have the fixing card of a usefulness to fix.

The circular plate washer on the rotary handle and the circular plate washer of adjustment spoon all indicate 1 scale outward.

Contain three axles that can rotate 360 ° in the utility model, they are orthogonal each other.After a heterogeneous body jewel places instrument, adjust this three rotating shafts, just can easily find the optical axis of crystal, and determine that it has angle between several optical axises and optical axis, thereby identify exactly and identified the true and false of jewel.Can identify gem and jade finished product, pass finished product and the raw material of all transparent heterogeneous bodies.Can put into one during evaluation to several jewels, compare observation simultaneously.Assessor can use under any white light and needn't attach any special light sources.The utility model volume is little, function is complete, qualification result is accurate, reliable results, be placed in the coat pocket and promptly take away, be fit to each level jewelry professional and gemstone testing personage, use as can buy raw material easily the time, also can when store sales, prove that to client the gem and jade that they buy is reliably, also can play the usefulness of gem and jade for general bullion fan.
