Abstract
An optical bench of a good using effect comprises a base. A front end of the base is fixedly connected with a measuring scale. A screen seat, a convex lens seat and candle holders are slidably connected onto the base. A screen is inserted onto the screen seat. A convex lens is inserted onto the convex lens seat. A lower sleeve is fixedly connected onto the candle holder. A candle sleeve is sleeved into the lower sleeve. The candle sleeve and the lower sleeve are connected through an adjusting nut.
Description
Technical field
The utility model relates to a kind of realia, relates in particular to a kind of optical bench.
Background technology
The optical bench that when doing the convex lens experiment, uses at present, comprise base, the base front end is fixedly connected with scale, slidely connect the screen seat on the base, convex lens microscope base and candle stand, be plugged with screen on the screen seat, be plugged with convex lens on the convex lens microscope base, when using the optical bench of this structure, the screen seat, convex lens microscope base and candle stand can move as required, but when doing experiment, candle has the long weak point that has, and highly is difficult to control, and the fixing trouble of candle, when needs point candle, candle is erected toward a wax oil on the candle stand, can scald one's hand but do so careless wax oil, move left and right candle in the process of experiment, candle is fallen down light inflammable thing, and remaining when a bit of behind the candle combustion, just can't use, cause the waste of resource, result of use is poor.
Summary of the invention
The purpose of this utility model provides the good optical bench of a kind of result of use.
For achieving the above object, the technical solution adopted in the utility model is: a kind of optical bench, comprise base, the base front end is fixedly connected with scale, slidely connects screen seat, convex lens microscope base and candle stand on the base, is plugged with screen on the screen seat, be plugged with convex lens on the convex lens microscope base, it is characterized in that: be fixedly connected with lower sleeve on the candle stand, be socketed with candle sleeve in the lower sleeve, be connected by setting nut between candle sleeve and the lower sleeve.
In this structure, candle stand is a plurality of.
The utility model has the advantages of and be: because this structure of the present utility model, so when using the utility model, can directly candle be inserted in the candle sleeve, fixed, result of use is good.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the accompanying drawing: 1, setting nut; 2, candle sleeve; 3, screen; 4, screen seat; 5, convex lens microscope base; 6, lower sleeve; 7, candle stand; 8, scale; 9, base.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model as shown in Figure 1, a kind of optical bench, comprise base 9, base 9 front ends are fixedly connected with scale 8, slidely connect screen seat 4, convex lens microscope base 5 and candle stand 7 on the base 9, are plugged with screen 3 on the screen seat 4, be plugged with convex lens on the convex lens microscope base 5, it is characterized in that: be fixedly connected with lower sleeve 6 on the candle stand 7, be socketed with candle sleeve 2 in the lower sleeve 6, be connected by setting nut 1 between candle sleeve 2 and the lower sleeve 6.In the present embodiment, candle stand 7 is a plurality of.
Use the utility model, even when candle only is left seldom, also can be placed directly in the candle sleeve and uses, economize on resources, result of use is good.
