Abstract
The utility model belongs to the field of stationery goods, which relates to a stationery case which can be used as a telescope. One end of the broader side of a rectangular stationery case is provided with a group of object lenses, and the other end of the broader side of the rectangular stationery case is provided with a group of eye lenses. The stationery case can be used as an ordinary stationery case in normal times. In telescoping time, a pair of Galilean binoculars is formed by that plates which are hidden on the bottom of the stationery case are unfolded and combined in a surrounding mode to help a user extend visual field and see details of pictures and words on a blackboard, which can not be easily distinguished. The utility model can be used as a stationery and can be used as a practical tool and a toy.
Description
The utility model belongs to the cultural goods field.
The student is on the classroom, often need copy the content that teacher writes on the blackboard, sometimes because some local teacher writes not clearly, or some symbol and mark are too little, or the seat is distant far from blackboard, or hypometropia, or reason such as overcast and rainy light is bad, cause the student unclear, thereby brought influence to study to a certain extent some local detail explanations of picture and text on the blackboard.And existing writing case can not help the student to solve this practical problem.
The utility model is exactly at this situation, for numerous students provide a kind of writing case with telescope function, it is provided with a cover optical system on writing case, writing case and telescope are combined together, can use as writing case, can have in eyesight again and treat as telescope usefulness in limited time, reach the purpose of extending eyesight.
Design of the present utility model is such:
Wide side two ends at common rectangle writing case, one end is provided with one group of object lens, and the other end is provided with one group of eyepiece, object lens convex lens, the eyepiece concavees lens, the length of focal length and writing case adapts, and the use to writing case does not at ordinary times influence, in the time of looking in the distance, utilize the expansion of the box wall of writing case or box body bottom plate to surround, object lens and eyepiece are in the chamber of a sealing, can form Galileo formula bitubular telescopic system, thereby writing case can be used as telescope.The time spent can not amounted to withdrawal with plate again, is hidden in the box body bottom.Object lens and eyepiece can use the inexpensive polystyrene plastics optical mirror slip of light weight.
Owing to adopt above scheme, make that this utility model is simple in structure, with low cost.Being a kind of schooling apparatus, is again a utility and toy simultaneously.
The utility model is described in further detail below in conjunction with two embodiment.
Fig. 1 is the structural representation of first embodiment.
Fig. 2,3,4,5 is structural representations of second embodiment, wherein:
Fig. 2, Fig. 3 be box body when being in the normal state above and following overall schematic.
Fig. 4 is box body is transformed into the state of looking in the distance by normality a transformation schematic diagram.
Fig. 5 is that box body is in the overall schematic when looking in the distance state.
With reference to Fig. 1, a rectangle plastic box body (1), there is certain thickness in box group in both sides, wherein has two bigger object lens slots (3) in the left side box group (2), to insert two identical object lens eyeglasses (4); Have two less eyepiece slots (6) in the right side box group (5), to insert two identical eyepiece eyeglasses (7).Dividing plate (8) traverses the middle part, with being divided into two independently spaces in the box body, can adorn stationery at ordinary times, in the time of looking in the distance, pours out stationery, and the lid that closes can constitute binoculars.Adopt Galileo formula telescope configuration form, the object lens convex lens, the eyepiece concavees lens, by calculating as can be known, if objective focal length is 32 centimetres, eyepiece focal length is 8 centimetres, and then multiplication factor is 4 times, and at this moment the box body total length is about 24 centimetres.
With reference to Fig. 2,3,4,5, rectangle plastics or iron sheet box body (1), can be divided into two parts up and down, top is divided into the main part of writing case, the inner space is used to adorn stationery, in left side box group (2), an object lens slot (3) that Open Side Down is arranged, in right side box group (5), an eyepiece slot (6) that Open Side Down is arranged.The bottom is divided into the part of writing case, the folding plate (8,9,10,11,12) of placing.Wherein, be embedded with two identical object lens eyeglasses (4) on the plate (8), be embedded with two identical eyepiece eyeglasses (7) on the plate (9), plate (8), (9) do not connect together with box body, can insert respectively in object lens slot (3) and the eyepiece slot (6).Plate (10), (11), (12) all with the isometric wide homalographic of box bottom (13), plate (10) is connected on the plate (11), plate (11) and plate (12) are connected in again on the box body (1), they all can close folded along connecting line.These 5 plates are folded into 4 layers and are hidden in the box body bottom during normality, wherein, plate (8) and plate (9) are close to bottom surface (13) together and are ground floor, plate (10) is the second layer, plate (11) is the 3rd layer, plate (12) is last the 4th layer, and surpasses 14 by the little protruding of edge) and the both sides box small rut (15) of helping fasten with box body, press seal is inside with plate (8,9,10,11).Like this, configuration is just similar with ordinary writing case during normality, and is just slightly thicker.When looking in the distance, successively plate (12,11,10) is launched, take out plate (8,9), insert respectively in object lens slot (3) and the eyepiece slot (6), plate (10,11,12) is close to plate (8,9) surrounds, can constitute binoculars below writing case, bottom surface (13) are the bottom surface of top writing case, be again following telescopical end face, as shown in Figure 5.Adopt Galileo formula telescope form, the object lens convex lens, the eyepiece concavees lens, by calculating as can be known, if objective focal length is 32 centimetres, eyepiece focal length is 8 centimetres, and then multiplication factor is 4 times, and at this moment the box body total length is about 24 centimetres.
Claims (4)
1, a kind of writing case of looking in the distance, form by box body and optical system, it is characterized in that, two ends at writing case, one end is provided with one group of object lens, the other end is provided with one group of eyepiece, utilizes the space that formation can be used as lens barrel that surrounds of box wall or box body attaching material, and object lens and eyepiece are in the centered optical system.
