Abstract
The utility model provides a convenient and fast's grating safety base can solve experiment operation dumb under the existing condition, the problem of unable protection grating piece. The shape metal material that this base is (img file='DDA0000807059660000011. TIF'wi='94'he='55' /), the inboard of base contains 2 springs, 1 individual iron sheet and 1 cushion, the one end of spring is welded in the inboard of base, the other end welds on the iron sheet, the iron sheet is by spring extrusion another inboard contact with the base, only need during the use with the iron sheet to one side pulling of being equipped with the spring, it can to put into the grating piece, the cushion is put between grating piece and iron sheet, in case the grating is extrudeed the damage.
Description
Technical field
The utility model relates to one conveniently grating safety basement, places about the safety of lenticular lenses in " optical grating diffraction measures the wavelength of light " experiment for Experiment of College Physics.
Background technology
Utilizing diffraction grating to measure the wavelength of light is important Experiments of Optics in Experiment of College Physics, and the main operating instrument of this experiment is that diffraction grating is taken into account in light splitting.First will adjust spectrometer makes it reach measurement requirement, then diffraction grating is positioned over wavelength objective table being measured incident light.In experimental implementation process, diffraction grating is positioned on grating base, and the grating base in existing experiment cannot adjust neatly according to the thickness of lenticular lenses, is also unfavorable for the protection of grating.
Summary of the invention
The utility model provides one conveniently grating safety basement, contributes to the lenticular lenses of placing various gauge, and has certain protective effect to grating.
For realizing above-mentioned requirements, the technical solution of the utility model is: a kind of grating safety basement that spring and rubber cushion are housed.
Described base comprises 2 springs, 1 piece of iron plate and 1 rubber cushion.
2 spring one end of described base are welded in the inner side of base, and the other end is welded on iron plate, and by iron plate extruding and another interior side contacts of base;
Described rubber cushion can freely be dismantled, and is put between iron plate and lenticular lenses.
Effect of the present utility model is: iron plate, by spring compresses, with another interior side contacts of base, only need pull to the side that spring is housed during use and put into lenticular lenses by original state iron plate.For protection grating, between iron plate and lenticular lenses, place one piece of rubber cushion, in case grating is extruded damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: (1) rubber cushion; (2) iron plate; (3) spring.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figure 1, one is grating safety basement conveniently, comprises: (1) rubber cushion; (2) iron plate; (3) spring.
Described base is
shape metal material.
Described spring is welded in inside base and between iron plate, makes iron plate and another interior side contacts of base by elastic force.
Described rubber cushion is between iron plate and the lenticular lenses of placing.
Claims (3)
1. a conveniently grating safety basement, is characterized in that: this base is
