Abstract
The utility model belongs to the technical field of a teaching instrument demonstration. More particularly, an infinite reflection demonstration apparatus for a flat mirror is provided. The apparatus comprises a support platform, a square shaped mounting table, a reverted U shape box, a light reflection plate and an LED light. The beneficial effects of the apparatus comprise that it has a simple structure and when assembled, the outlook is compact and good looking. Small in size and convenient to transport and assemble as well as cheap to make, the apparatus also has a long service lifetime. Since a blue light LED light band is adopted into the apparatus rather than ordinary fluorescent lamps, the apparatus can achieve a good demonstration effect so as to make students interested in learning more from the perspective of teaching. At the same time, the apparatus of the utility model is simple in structure, making it easier to be promoted.
Description
Technical field
The utility model relates to demonstration instrument for teaching device technical field, is specifically related to the unlimited reflection demonstrating device of a kind of level crossing.
Background technology
Known from institute, light reflection principle is the basic studies knowledge in junior middle school physics teaching, in current teaching practice and the demonstration of science popularization instrument, generally adopt a level crossing to explain and demonstrate, but this demenstration method is more dull and more abstract concerning learner, can not effectively stimulate learning interest, therefore directly perceived, interesting demonstration light reflection principle how, improves students ' interest of study, improves study and like that efficiency is institute's problem demanding prompt solution in current teaching and science popularization exhibition.
At present, " the manual simulation firmament " is although solved this problem, but it need to arrive in specific environment and the number of once learning is limited and it is higher to manufacture cost, while its volume of some demonstration instruments is on the market large, heavy, be difficult for assembling transport and adopt fluorescent tube, it is frangible, demonstration weak effect, has potential safety hazard.
Therefore,, based on the problems referred to above, the utility model provides a kind of level crossing unlimited reflection demonstrating device.
Utility model content
Utility model object: the purpose of this utility model provides a kind of level crossing unlimited reflection demonstrating device, solve existing plane reflection apparatus for demonstrating cost of manufacture high, assemble loaded down with trivial details and problem such as demonstration weak effect etc., and then improve demonstration effect, reach teaching and science popularization object.
Technical scheme: the unlimited reflection demonstrating device of a kind of level crossing, comprises brace table, square installation desktop, inverted U box, reflector and LED lamp; Square installation desktop is installed in described brace table top; In the middle of described square installation desktop, inverted U box is installed; Described reflector is that aluminium-plastic panel is arranged on dress inverted U box one side sidewall centre position; Described LED lamp is blue light, is evenly arranged on inverted U box.
Further described square installation desktop is flame-retardant board, and thickness is 20mm.
Further described reflector is white, and thickness is that 3mm, width are 18mm.
Compared with prior art, the beneficial effect of the unlimited reflection demonstrating device of a kind of level crossing of the present utility model is: 1, product structure is simple, and after assembling, outward appearance is small and exquisite elegant in appearance; 2, at the bottom of little, the easy carrying assembling of volume and production cost, long service life; 3, adopt blue LED lamp band to replace common daylight lamp, its good demonstration effect, is used in the upper students ' interest of study that effectively strengthens of teaching.While the utility model is simple in structure, easily popularization.

Wherein in figure, sequence number is as follows: 1-brace table, the square installation desktop of 2-, 3-inverted U box, 4-reflector, 5-LED lamp.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
The unlimited reflection demonstrating device of a kind of level crossing as shown in Figure 1, Figure 2, Figure 3 and Figure 4, comprises brace table 1, square installation desktop 2, inverted U box 3, reflector 4 and LED lamp 5; Square installation desktop 2 is installed in brace table 1 top; In the middle of square installation desktop 2, inverted U box 3 is installed; Reflector 4 fills inverted U box 3 one side sidewall centre positions for aluminium-plastic panel is arranged on; LED lamp 5 is blue light, is evenly arranged on inverted U box 3.
Further square installation desktop 2 is flame-retardant board, and thickness is 20mm.
Further reflector 4 is as shown in Figure 5 white, and thickness is that 3mm, width are 18mm.
Embodiment
After brace table 1, square installation desktop 2, inverted U box 3, reflector 4 and LED lamp 5 are assembled successively, LED lamp 5 lamp bands are powered, now light source forms i.e. " the endless gallery " of reflection on inverted U box 3 inwalls, this kind of demonstration effect stereoscopic sensation is strong, can effectively strengthen the understanding of learner to light principle on the one hand, and then improve learning interest and reach science popularization requirement, compact conformation, small and exquisite on the other hand, assembling simply can meet amateur's aim of learning.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvement, these improve and also should be considered as protection domain of the present utility model.
