Description
Technical field
The portable simple projection arrangement belongs to amusement with projection, projection arrangement field, is specifically related to a kind of portable simple projection arrangement.
Background technology
Present most projector equipment is mainly used in teaching and projection, and most of structure is complicated, and volume is bigger, is not easy to carry; And be specifically designed to projection arrangement that personal entertainment uses seldom, though also be useful on the projecting device that children's heuristic teaching is used, but projecting device itself all needs external power supply or power autonomous, and need prepare corresponding lantern slide and a large amount of pictures, the same problem that is not easy to carry that exists, as the patent No. is 200520012800.1 Chinese patent, and the patent No. is that 91215787.9 Chinese patent all belongs to above-mentioned situation.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of portable, need not to connect power supply in addition, need not to prepare separately the portable simple projection arrangement of picture.
The technical scheme that its technical matters that solves the utility model adopts is: this portable simple projection arrangement, comprise top cover, convex lens, columniform case follower and light source display, it is characterized in that: level crossing is equipped with in the bottom surface of top cover, top cover is connected with the sleeve outer upper ends by coupling shaft, the sleeve middle and lower part is provided with external thread, lifting support top is set in outside, sleeve lower end, and convex lens pass through the pickup groove horizontal fixed in the top of sleeve lining.
The center line of described convex lens longitudinal section is to the distance of the sleeve baseplane focal distance f less than convex lens.
Described lifting support top is provided with the internal thread that is complementary with sleeve, and the bottom is tapered.
Described top cover is drops, can cover the top of sleeve fully.
Compared with prior art, the beneficial effect that the utility model had is:
1, simple in structure, easy to operate, need not externally or power autonomous, safe and reliable, cost of manufacture is cheap;
2, volume is little, and is easy to carry, need not to carry lantern slide or picture etc., and only needing has the light source display of storage, playing function to get final product with the mobile phone of carrying, MP4 etc., is convenient to carry;
3, teach through lively activities, both can increase a bit fresh enjoyment after dinner, knowledge information can be passed to children in the mode of playing again, increase the interest of its study, make its happy in recreation, study easily.
Description of drawings
Fig. 1 is the utility model front view synoptic diagram.
Fig. 2 is the utility model vertical view synoptic diagram.
Wherein: 1, top cover 2, coupling shaft 3, pickup groove 4, convex lens 5, sleeve 6, lifting support 7, light source display.
Fig. 1～2nd, most preferred embodiment of the present utility model is described further below in conjunction with 1～2 pair of the utility model of accompanying drawing:
Embodiment
With reference to accompanying drawing 1～2:
This portable simple projection arrangement, by top cover 1, coupling shaft 2, pickup groove 3, convex lens 4, columniform case follower 5, lifting support 6 and light source display 7 are formed, top cover 1 is drops, level crossing is equipped with in the bottom surface, can cover the top of sleeve 5 fully, be connected with sleeve 5 outer upper ends by coupling shaft 2, sleeve 5 middle and lower parts are provided with external thread, lifting support 6 tops are provided with the internal thread that is complementary with sleeve 5, top is set in outside, sleeve 5 lower end, the bottom is tapered, in the top of sleeve 5 inwalls, the center line of convex lens 4 longitudinal sections is to the distance of the sleeve 5 baseplanes focal distance f less than convex lens 4 by pickup groove 3 horizontal fixed for convex lens 4.
The course of work is as follows:
Principle of work of the present utility model is according to the characteristics of convex lens to the refraction of light, and promptly the convex lens characteristics that converge light realize its projecting function.
The light source display of carrying 7 with playing function is put in lower central in the lifting support 6, converge to a bit after the image planoconvex lens 4 of light source display 7, according to the convex lens imaging law, adjust the screw thread between rotation and lifting support 6 and the sleeve 5, adjust the distance between light source display 7 and the convex lens 4, can make image planoconvex lens 4 reflect image big or little, upright or the different effect of standing upside down; When the distance between light source display 7 and the convex lens 4 was beyond two times of focal distance f of convex lens 4, presenting stands upside down dwindled real image; When between one times of focal distance f to two times focal length 2f of the distance between light source display 7 and the convex lens 4 at convex lens 4, presenting stands upside down amplifies real image; When in one times of focal distance f of the distance between light source display 7 and the convex lens 4 at convex lens 4, present upright amplification void and think; When the distance between light source display 7 and the convex lens 4 equals one times of focal distance f of convex lens 4, not imaging.Adjust the rotational angle of top cover 1 at last, the image reflection that convex lens 4 are formed can be watched the projected picture of formation on nontransparent plane object.
Simple structure, cheap cost of manufacture need not to make its converter tools that becomes a kind of uniqueness by advantages such as other any power sources, and that gives people brings a kind of fresh enjoyment after dinner.Simultaneously, also can be used as a kind of learning tool, the knowledge information on the picture is passed to children in the mode of amusement, it is learnt in recreation.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
