Description

Novel gemolite
(1) technical field:
The utility model relates to a kind of microscope, particularly a kind of novel gemolite that is used to observe, detect jewel.
(2) background technology:
Traditional gemolite is by support, focus adjusting mechanism, and viewing head, epi-illuminator, trans-illuminator, the jewel folder is formed.Because the jewel of this gemolite folder is the leverage of a strap clamp, can only rotate and swing around pillar, can not according to measure needs the jewel end face that clamps is adjusted to vertical with optical axis, the therefore angle of energy measurement jewel not; In addition, because the lighting source that the conventional gemstone microscope uses generally is not a cold light source, so illuminating ray can make observed jewel temperature change, and influences measuring accuracy.
(3) summary of the invention:
The purpose of this utility model provides a kind of novel gemolite of being convenient to observe and accurately detecting jewel.
Novel gemolite of the present utility model, comprise base, support, focus adjusting mechanism, be fixed on the microscopic examination head of focus adjusting mechanism, the jewel folder, it is characterized in that it also comprises the dark field condenser that is placed on the support level platform, be fixed on the LED reflection luminaire that is positioned at dark field condenser top on the support, rack-mount light emitting diode trans-illuminator below the dark field condenser, described base has increased weight especially, link between base and the support, the jewel that is fixed on the dark field condenser by slide bar accompanies a mechanical arm, and mechanical arm is by joint shaft and slide bar hinge joint.
The dark field condenser comprises a rotating disk, be fixed on last shaft collar on the rotating disk and the lower fixed disk under rotating disk, have between last shaft collar and the rotating disk and go up row's ball, row's ball is down arranged between rotating disk and the lower fixed disk, rotating disk, to go up between shaft collar and the lower fixed disk be to roll to connect; Axle by down ball, lower clamping ring and friction pulley, go up ball and be fixed in the shrinkage pool of rotating disk, friction pulley is positioned at the bottom of axle and at the shrinkage pool of rotating disk, contacts with shrinkage pool, handwheel is installed in the axle upper end.
Novel gemolite of the present utility model has been compared following advantage with existing product:
(1) base adopts heavy ferrous metal, thereby makes base have enough weight to guarantee that support can overturning when oblique view, and existing product adopts aluminium alloy mostly, and is in light weight, easy overturning when riding.
(2) outer ring of dark field condenser can be rotated, and increases the angle in the orientation of observing jewel, can measure the angle of jewel seamed edge.
(3) the jewel folder has increased a joint, and energy top view jewel is measured jewel seamed edge angle thereby cooperate dark field condenser outer ring to rotate.
(4) illuminator of reflected light and transillumination device have all adopted state-of-the-art technology great power LED light emitting diode, and light spectrum is abundant, and the colour temperature height approaches daylight, and light is cold light, can not make the temperature of observed jewel and change.
(4) description of drawings:
Fig. 1 is the structural representation of novel gemolite of the present utility model;
Fig. 2 is the dark field condenser of novel gemolite of the present utility model and the structural drawing of jewel folder.
(5) embodiment:
Below the contrast accompanying drawing further specifies the structure of novel gemolite of the present utility model:
As shown in Figure 1, be connected by a rotating shaft between support 2 and the base, very heavy iron plate of base 1 usefulness is made, and support 2 is not easy overturning when swinging oblique view backward.Focus adjusting mechanism 3, the structure of microscopic examination 4 that is fixed on focus adjusting mechanism 3 are the same with existing gemolite, novel gemolite principal feature of the present utility model is that a dark field condenser 6 that is placed on support 2 horizontal stands is arranged, its outer ring is rotatable, has increased the orientation and the angle of observing jewel.
The structure of scotopia condenser 6 is such, it comprises a rotating disk 12, be fixed on last shaft collar 13 and the lower fixed disk under rotating disk 12 14 on the rotating disk 12, the row's of going up ball 15 is arranged between last shaft collar 13 and the rotating disk 12, down row's ball 16 is arranged between rotating disk 12 and the lower fixed disk 14, and rotating disk 12, to go up between shaft collar 13 and the lower fixed disk 14 be to roll to connect; Axle 17 by down ball 18, lower clamping ring 19 and friction pulley 20, go up ball 21 and be fixed in the shrinkage pool 22 of rotating disk 12, friction pulley 20 is positioned at the bottom of axle 17 and at the shrinkage pool 22 of rotating disk 12, contacts with shrinkage pool 22, handwheel 23 is installed in axle 17 upper ends.
Jewel folder 5 is fixed on the dark field condenser 6 by slide bar 9, is that with existing gemolite difference jewel folder 5 has a mechanical arm 10, mechanical arm by joint shaft 11 hinge joints on the slide bar 9 of jewel folder 5.
The mechanical arm of jewel folder 5 can rotate by the slide bar 9 of joint shaft 11 around jewel folder 5, thereby makes the jewel end face of clamping vertical with optical axis, and the jewel that can top view clamps.Rotate handwheel 23, rotating disk 12 just can rotate.Just can read the angle that turns over by the scale on the rotating disk 12, thereby measure the angle of jewel seamed edge.
Be positioned at dark field condenser 6 upper fixed on the support 2 a LED reflection luminaire 7 is being arranged, light emitting diode trans-illuminator 8 is being installed below dark field condenser 6 on support 2.
LED reflection luminaire 7, light emitting diode trans-illuminator 8 have adopted state-of-the-art technology great power LED light emitting diode, and the light spectrum that sends is abundant, the colour temperature handing-over is bordering on daylight, and light is cold light, does not influence the temperature of observed jewel, thereby has improved the accuracy of jewel observation.
When needs carry out bright field illumination, the dark field condenser 6 on the placing rack 2 is changed to round worktable 24, the similar of the structure of round worktable 24 and dark field condenser 6, its outer ring is rotatable, condenser has been reduced for band through hole platform structure in the inside, thereby realizes bright field illumination.
The mains lighting supply of novel gemolite of the present utility model is used the rechargeable battery power supply, uses saferly, and also can use in the place of no civil power.
