Abstract
From horizon light gratings, comprise base, frame, hanger and plummet, base is U-shaped, there are two No. II expansion screws its front portion, frame is rectangle, it is rectangular through holes in the middle part of it, hanger is rectangle, it is fixedly connected on leading flank side to the left, frame upper end, its upper side has cone tanks, be provided with No. I expansion screw in the middle part of it, and plummet is connected with by cord with No. I expansion screw lower central and meets: when the downside of base is put on surface level, and the tip of plummet is almost suffered and points to reference point.Grating glass plate is put into base bar shaped groove, be close on frame, two No. II expansion screws are tightened, until clamping Grating glass plate, thus form from horizontal grating.Beneficial effect is, simple and practical, successful.
Description
Technical field
The utility model belongs to physical experiment apparatus field, relates to a kind of from horizon light gratings.
Background technology
When doing grating diffraction experiment, first must mix up spectrometer, wherein the step of most critical is coarse adjustment and fine tuning, namely auto-collimator lens barrel and article carrying platform is all transferred to approximate horizontal position, is then put into by grating on objective table and carries out fine tuning.Owing to will adjust three screws under article carrying platform and the tilting screw under auto-collimator lens barrel, a lot of experimenter can not be transferred to approximate horizontal position article carrying platform and auto-collimator lens barrel at all by feel, and experiment cannot be continued.In addition, the Grating glass plate that experiment is commonly used is generally be fixed on base to form grating, but fixing usually not firm, and the not clamping Grating glass plate of base, has an impact to experimental result.
Summary of the invention
In order to solve Problems existing, the purpose of this utility model is to provide a kind of from horizon light gratings, intuitively rapidly article carrying platform and auto-collimator lens barrel can be transferred to approximate horizontal position, solve the problem of the not clamping Grating glass plate of base simultaneously.
The utility model solves the technical scheme that its technical matters adopts: from horizon light gratings, comprise base, frame, hanger and plummet, it is characterized in that: described base is U-shaped, its front portion is provided with two No. II expansion screws, described frame is rectangle, it is rectangular through holes in the middle part of it, described hanger is cuboid, it is fixedly connected on leading flank side to the left, frame upper end, its upper side has cone tanks, No. I expansion screw is provided with in the middle part of it, described plummet is connected by cord with No. I expansion screw lower center and meets: when the downside of base is put on surface level, the tip of plummet is almost close to and points to reference point.
During use, Grating glass plate is put into base bar shaped groove, be close on frame, two No. II expansion screws are tightened, until clamping Grating glass plate, thus form from horizontal grating.To be put on the article carrying platform of spectrometer from horizontal grating, regulate three screws under article carrying platform respectively, until when plummet is static, reference point is just in time aimed in its tip, and now article carrying platform is in horizontality substantially; Again to be put into from horizontal grating above auto-collimator lens barrel and with hand according to, regulate the tilting screw under auto-collimator lens barrel, until when plummet is static, reference point is just in time aimed in its tip, and now auto-collimator lens barrel is also in horizontality substantially.Coarse adjustment end-of-job also can continue to utilize to carry out fine tuning from horizontal grating pair spectrometer.Grating diffraction experiment can be carried out further.After instrument regulation is good, plummet can be put into conical tank, experiment can be started.
The beneficial effects of the utility model are, simple and convenient practicality, and experiment effect is obvious, safety, are easy to produce.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail:
As shown in Figure 1, the utility model is from horizon light gratings, comprise base 1, frame 2, hanger 4 and plummet 8, it is characterized in that: described base 1 is U-shaped, its front portion is provided with two No. II expansion screws 11, described frame 2 is rectangle, it is rectangular through holes 3 in the middle part of it, described hanger 4 is cuboid, it is fixedly connected on leading flank side to the left, frame upper end, its upper side has cone tanks 5, No. I expansion screw 6 is provided with in the middle part of it, described plummet 8 is connected by cord 7 with No. I expansion screw 6 lower center and meets: when the downside of base 1 is put on surface level, the tip of plummet 8 is almost close to and points to reference point 10.
During use, Grating glass plate is put into base 1 bar shaped groove, be close on frame 2, two No. II expansion screws 11 are tightened, until clamping Grating glass plate, thus form from horizontal grating.To be put on the article carrying platform of spectrometer from horizontal grating, regulate three screws under article carrying platform respectively, until when plummet is static, reference point 10 is just in time aimed at its tip, and now article carrying platform is in horizontality substantially; Again to be put into from horizontal grating above auto-collimator lens barrel and with hand according to, regulate the tilting screw under auto-collimator lens barrel, until when plummet is static, reference point is just in time aimed in its tip, and now auto-collimator lens barrel is also in horizontality substantially.Coarse adjustment end-of-job also can continue to utilize to carry out fine tuning from horizontal grating pair spectrometer.Grating diffraction experiment can be carried out further.After instrument regulation is good, plummet 8 can be put into conical tank 5, experiment can be started.
