The device comprises a cross rod, a rotating shaft, a sleeve rod, a base and a light fixture, wherein the sleeve rod is vertically arranged on the base; the bottom of the sleeve rod is indent; the surface of the base is convex so as to match with the bottom of the sleeve rod; the cross rod is hollow and is vertically arranged on the top end of the sleeve rod through the rotating shaft; and the light fixture is arranged inside the cross rod. Compared with the prior art, the utility model is reliable, can conveniently finish the optical experiments like small hole imaging, eliminates the potential danger of using the flammable light source like candles to have an experiment, is capable of regulating the horizontal distance and the vertical distance of the equipment and the radiating angle of the cross rod according to the requirement and is convenient for teachers to have a class and explain.

Description

Novel experimental light sources device

1, technical field

The utility model relates to the teaching aid technical field, specifically a kind of novel experimental light sources device.

2, background technology

In the existing teaching, form of teaching by experiment is more and more general, so how to allow more simple and convenient, the easy operation of experimental apparatus, being easy to carry becomes the common purpose of numerous teachers, particularly in the teaching process of Experiments of Optics, major part is still used the utensil of combustible light source as experiment, this mode brings certain hidden danger for undoubtedly the security of experiment, and apparatus is not easy to carry, and brings certain trouble to experimental teaching.

3, summary of the invention

The utility model is at above-mentioned the deficiencies in the prior art, and a kind of novel experimental light sources device is provided.

Novel experimental light sources device of the present utility model is realized in the following manner, structure comprises cross bar, rotating shaft, loop bar, base and light fixture, wherein loop bar is vertically set on the base, and the bottom face of loop bar is arranged to interior concave shape, susceptor surface is arranged to the convex shape that matches with the loop bar bottom, cross bar is arranged to hollow form and is vertically set on the top of loop bar by rotating shaft, and light fixture is arranged on cross bar inside.

Power supply is arranged on cross bar inside, and switch is arranged on the outer face of cross bar end, and light fixture, power supply and switch are set together by the circuit connection of cross bar inside.

Loop bar is set together by lock valve.

The nose bar of loop bar and base is provided with the scale mark sign.

The utility model is compared with prior art, has following outstanding beneficial effect:

(1) safe and reliable, the optical test that utilizes this portable light source can finish easily in the Physical Experiment is operated, and has eliminated because of using flammability light sources such as candle to do the hidden danger of experiment.

(2) conveniently moving, the convex character shape by base matches with the concave shape of loop bar bottom and is set together, and realizes that easily loop bar moves horizontally on base, and adjusts the height change of loop bar by lock valve, realizes that by rotating shaft is convenient cross bar rotates on the direction of border.

(3) cultivate the interest that the student learns, the simple mode that relies on the teacher to tell about knowledge and draw on blackboard is given lessons, the student is produced knowledge be weary of sense, can not only make student's fast understanding by experiment and grasp knowledge, and create a kind of atmosphere of learning like a cork, improve the interest of student's learning knowledge, and then in interest, improve constantly school grade.

5, embodiment

Explain below with reference to Figure of description novel experimental light sources device of the present utility model being done.

As shown in Figure 1, novel experimental light sources apparatus structure of the present utility model comprises cross bar 2, rotating shaft 4, loop bar 5, base 7 and light fixture 1, wherein loop bar 5 is vertically set on the base 7, and the bottom face of loop bar 5 is arranged to interior concave shape, the convex shape that matches with loop bar 5 bottoms is arranged on base 7 surfaces, cross bar 2 is arranged to hollow form and is vertically set on the top of loop bar 5 by rotating shaft 4, light fixture 1 is arranged on cross bar 2 inside, power supply is arranged on cross bar 2 inside, switch 3 is arranged on the outer face of cross bar 2 ends, light fixture 1, power supply and switch 3 are set together by the circuit connection of cross bar 2 inside, loop bar 5 is set together by lock valve 6, and the nose bar of loop bar 5 and base 7 is provided with scale mark 8 signs.

Loop bar 5 is equipped with base 7 is in the same place, and the moving of horizontal direction distance that can realize loop bars 5 by base 7, realize that by lock valve 6 loop bar 5 distance in vertical direction moves, realize the rotation of cross bar 2 on the direction of border by rotating shaft 4, in the process that moves, by the scale mark on base 7 and the loop bar 28 sign, can grasp mobile easily apart from length.

Cross bar 2 inside of hollow form can be provided with various types of lamps source as required, as the use light emitting diode, and the supply unit that adopts respective electrical to lie prostrate, can also as required light fixture 1 be pulled down processing, in order to cleaning and maintain light fixture 1.

The use step of novel experimental light sources device of the present utility model is as follows:

By switch 3 control light fixtures 1, light passes through the cross bar 2 of hollow form to external exposure, adjusts the irradiating angle of horizontal range, vertical range and the cross bar 2 of instrument simultaneously as required.

Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
