Abstract

The utility model relates to an optical teaching appliance, in particular to a telescopic periscope for studying the physical conceptions such as the reflection of the light, the emission of the light, the convergence of the light, etc. The utility model can be combined to form into the periscope or the telescopic periscope with telescoping function and the periscope function according to the teaching requirement. In virtue of adopting the casing with the special structure and lens with the special structure, students can mount and dismantle the utility model by themselves for implementing the visual teaching and the good teaching effect. At the same time, the utility model is a novel optical toy for children.

Description

Tele-periscope

The utility model relates to a kind of optics teaching aid (toy).Be specially adapted to physical concepts such as primary and secondary students learn reflection of light, disperse, convergence.Simultaneously, it also is a kind of toy for children of novelty.

Existing toy telescope does not possess to dive hopes function.And periscope can not be looked in the distance.As the classroom teaching aid, their common drawback is to dismantle, and influences teaching efficiency.

The purpose of this utility model then is the problem at above-mentioned existence, has proposed a kind of formula of looking in the distance periscope that can possess telescope and periscope function simultaneously, and it can adorn removable, and it is very directly perceived to impart knowledge to students.

The utility model has the advantages that:

The formula of the looking in the distance periscope that is assembled into when being used to watch large-scale performance, sports tournament, can make observer's sight line improve about 30 centimeters, is unlikely to by the tall block vision in front row.Horizontal positioned can make the sight line translation when observing, and is used for children and plays.

When the formula of originally looking in the distance periscope also can be used for students military training, from trench, watch surface state.

The technical solution of the utility model is:

In square stack shell, have two level crossings that are parallel to each other and with a slice convex lens and a slice concavees lens at level crossing angle at 45, and each eyeglass all be an interior circle square structure outward.

Fig. 1 is the external structure synoptic diagram.

Fig. 2 is an interior lens riding position synoptic diagram.

Fig. 3 is convex lens and cross-sectional schematic thereof.

Fig. 4 is concavees lens and cross-sectional schematic thereof.

Fig. 5 is the level crossing synoptic diagram.

Be square stack shell among Fig. 1, it is formed by connecting with self-tapping

screw

3,4 by two identical shells 2.

Among Fig. 2 the 5, the 6th, level crossing, the 7th, convex lens, the 8th, concavees lens, the 9, the 10th, mounting screw is used the hole.

Fig. 3 is convex lens and cutaway view thereof. For the ease of adopting plug-type installation method, adopted the outer square structure of inner circle.

Fig. 4 is concavees lens and cutaway view thereof, also adopts the outer square structure of inner circle.

Fig. 5 is the level crossing schematic diagram.

Below in conjunction with accompanying drawing, further specify the technical solution of the utility model.

Get 1 shell 2, with the convex lens of Fig. 3, the concavees lens of Fig. 4, two of the level crossings of Fig. 5 insert 7 among Fig. 2,8,5,6 positions respectively, because the eyeglass installation position is equipped with the location with protruding little muscle 11, so lens orientation is accurate, can not move.Other gets a shell, closes in the shell of going up eyeglass, penetrates from

screw hole

3,4 with two M3 * 20 self-tapping screws, screws in the

screw

9,10, and assembly work so far finishes.

When the utility model is done the teaching aid use, can only insert level crossing earlier, screw on screw, promptly constitute periscope, can pull down screw after the demonstration, pack into convex lens and concavees lens, study telescope principle of work.So just having overcome in the past, the student can't see periscope or the in-built defective of telescope.Do it yourself to install by the student and can make teaching more directly perceived.

Embodiment 1:

Originally the formula of looking in the distance periscope stack shell 1 is by plastic injection-moulded forming such as modified polyphenyl, AS, ABS.Level crossing is made by common 3mm glass mirror.Convex lens and concavees lens are made by transparent polyphenyl 372, eyeglass is installed is protruded the location of little muscle as eyeglass, insert eyeglass during assembling and get final product.Adopt family to change the stack shell 1 of symmetrical structure, be made up of two identical shells 2, a mould gets final product.

Claims

1, a kind of formula periscope of looking in the distance is characterized in that having two level crossings that are parallel to each other to reach and a slice convex lens and a slice concavees lens at level crossing angle at 45 in square stack shell, and each eyeglass all is the outer square structure of interior circle.
