Abstract
The invention discloses a viewer being able to adjust light intensity on a crystal growing furnace. The viewer includes a lens barrel, wherein the lens barrel is formed by an upper end cover, a rotation apparatus and a lower end cover; a gray lens is arranged on the top end of the rotation apparatus; the upper end cover is pressed on the gray lens; a holder with a concave structure is arranged in the rotation apparatus; a gray progressive lens is arranged in the groove at the holder with the concave structure; a ring gear is arranged on the outer wall of the holder; a rotation gear is inlaid in the housing of the rotation apparatus; the rotation gear is mutually meshed with the ring gear; and the lower end cover is arranged below the holder. As a holding plate of the viewer being able to adjust light intensity on a crystal growing furnace is made of a sapphire sheet, the viewer being able to adjust light intensity on a crystal growing furnace can effectively prevent fragmentation of the lens damaging eyes, and the light intensity can be adjusted according to the requirement of an operator so that the work efficiency can be greatly improved.
Description
Technical field
The technical field that the present invention relates to crystal growth, relates in particular to tunable optical on a kind of crystal growing furnaceThe peephole of line strength
Background technology
Along with improving constantly of modernization level, more and more vast for the demand of crystal amount, at present,Operator's growth furnace seeding at high temperature, just by observing under a colored lens, due to growthIn stove, temperature is very high, may cause eyeglass cracked, damage people's eyes, and the each rank of crystal growing furnaceSection, in stove, temperature differs, so colored lens of light can make cannot catch one when observationA little details, therefore, how tunable optical line strength, can not injure eyes be that those skilled in the art need at presentThe technical problem solving.
Summary of the invention
The invention provides a kind of simple to operate, tunable optical line strength, can not injure the peephole of eyes.
On crystal growing furnace, a peephole for tunable optical line strength, comprises lens barrel, and described lens barrel isFormed by upper end cover, whirligig and bottom end cover, on the top of described whirligig, grey is installedEyeglass, and upper end cover is pressed on grey eyeglass; In described whirligig, be provided with " recessed " shape structureLaying rack, the groove of the laying rack of " recessed " shape structure is provided with grey progressive lenses, laying rackOuter wall is provided with ring gear, and the shell of described whirligig is provided with on two horizontal linesThrough hole, leaves gear shaft between two through holes, and gear shaft is provided with swing pinion outward, and swing pinionIntermeshing with ring gear, under described support bracket, bottom end cover is installed, regulate and revolve by operatorSwing pinion on rotary device, swing pinion drives the grey progressive lenses being arranged in laying rack, therebyOperator can carry out according to the temperature in stove the power of light regulating.
Between described upper end cover and whirligig, be threaded connection, between bottom end cover and whirligigBe threaded connection, be threaded connection each parts are easy for installation and removal, to replace mirrorSheet.
The plate that holds in described laying rack adopts sapphire sheet, because sapphire has the heat-resisting of raisingProperty, effectively prevent eyeglass explosion.
The present invention compared with prior art has the following advantages:
In lens barrel, be provided with under grey eyeglass, grey eyeglass plays the damage of protecting eyes not to be subject to high lightWound, then adds grey progressive lenses, guarantees to carry out light power in the situation that not injuring eyes againRegulate; Color-changing lens adopts grey, can effectively reduce light intensity, and there will not be obvious aberration;Between each parts of lens barrel, all can mount and dismount, so that the replacement of eyeglass.
Brief description of the drawings
Fig. 1 is peephole cross-sectional view of the present invention.
Reference numeral: 1, laying rack; 2, whirligig; 3, upper end cover; 4, grey eyeglass; 5,Ring gear; 6, grey progressive lenses; 7, bottom end cover; 8, swing pinion.
Detailed description of the invention
In order to deepen the understanding of the present invention, further to the present invention below in conjunction with embodiment and accompanying drawingDescribe in detail, this embodiment is only bright for explaining the present invention, does not form limiting the scope of the present invention.
As shown in Figure 1, comprise lens barrel, lens barrel is to have upper end cover 3, whirligig 2 and bottom end cover 7Composition, on the top of described whirligig 2, grey eyeglass 4 is installed, and upper end cover 3 is pressed in ashOn look eyeglass 4; In described whirligig 2, be provided with the laying rack 1 of " recessed " shape structure, " recessed "The groove of the laying rack 1 of shape structure is provided with grey progressive lenses 6, on the outer wall of laying rack 1, establishesHave ring gear 5, the shell of described whirligig 2 is provided with two through holes on a horizontal line,Between two through holes, leave gear shaft, gear shaft is provided with swing pinion 8 outward, and swing pinion 8 withRing gear 5 is intermeshing, and described support bracket is provided with bottom end cover 71 time.
Between described upper end cover 3 and whirligig 2, be threaded connection bottom end cover 7 and rotation dressBetween putting 2, be threaded connection.
The plate that holds in described laying rack 1 adopts sapphire sheet.
When use, according to operator, temperature in stove is regulated the rotation on adjusting rotating device 2Gear 8, swing pinion 8 drives laying rack 1 to rotate, thus the grey progressive lenses on laying rack 16 rotation, makes the adjustable light intensity of operator.
