Description

Assembled lens imaging demonstrator for popular science teaching

technical field

The invention belongs to the technical field of popular science teaching appliances, in particular to an assembled lens imaging demonstrator for popular science teaching.

Background technique

At present, when the school teaches physics, it is basically theoretical, and there are not many practical applications and actual operations. As a result, many students are very clear about theoretical knowledge, but they have not even seen it in practice. It has caused many students to have high eyesight and low hands, which has a great impact on the all-round development of students. Lens imaging is often seen and used in daily life, and it is the basis for the operation of many devices. In the current school teaching, there is no simple device to intuitively demonstrate the working principle and working conditions of lens imaging.

Contents of the invention

The purpose of the present invention is to solve the above-mentioned technical problems, to provide a more intuitive and simple display of the working conditions and principles of lens imaging, and to enhance the interest of experiments at the same time as an assembled lens imaging demonstrator for science teaching. The technical scheme is as follows:

The assembled lens imaging demonstrator for popular science teaching is characterized in that it includes an outer frame and an inner frame, and the outer frame is assembled from two outer plates, an outer bottom plate and an outer rear plate, and the outer rear plate is provided with There is a film, and guide rails are set on the outer bottom plate; the inner frame is composed of two inner side plates, an inner bottom plate and an inner front plate, a lens is arranged on the inner front plate, and a guide rail is provided on the inner bottom plate. The guide rail is inserted in the guide groove, and the inner frame slides in the outer frame through the guiding action of the guide rail and the guide groove, and the bottom of the outer frame is provided with feet. The outer frame is mainly used to place the film, which is convenient for observation and imaging, and also provides a sports place for the inner frame. The inner frame is mainly used to place the lens, by adjusting the position of the inner frame in the outer frame to achieve a better image display on the film. The guide grooves and guide rails are mainly used to guide the moving direction of the inner frame, making imaging easier and simpler. Imaging can be achieved by moving the inner frame, which can increase the fun of students' experiments. The outer frame is assembled by two outer panels, outer bottom panel and outer rear panel, which can be assembled during use to enhance students' hands-on ability and make the imaging principle clearer during assembly.

In a preferred manner, the front ends of the legs are clamped on the outer rear panel and extend into the inside of the outer frame to form guide rails. The guide rail is the part where the front end of the foot extends into the outer frame, so that the foot can be used for multiple purposes. It does not need to add another part to realize the guiding function, making the production easier, and the assembly is simpler and more ingenious, which is more inspiring for students. .

In a preferred manner, the side of the outer rear plate is provided with a snap-fit groove opening downward, and the side of the outer plate is connected to the outer rear plate through the snap-fit groove. The clamping groove can make the connection between the outer rear panel and the outer panel more stable, and it is not easy to fall off and fall apart.

Preferably, the center of the inner front plate is provided with a lens groove, and the two sides of the inner front plate are connected with the inner plate through arc-shaped ear pieces. The curved ear piece of the inner front panel can well connect the inner panel and the inner front panel, making the connection more stable. At the same time, the arc-shaped ear piece will protrude from the inner panel to play a limiting role. When the inner frame moves in the outer frame, the inner frame will not completely slide into the outer frame.

Preferably, the film is a frosted translucent film.

The beneficial effect of the present invention is that the working condition and principle of lens imaging can be displayed more intuitively and simply, and at the same time, the interestingness of the experiment can be enhanced.

Detailed ways

Below in conjunction with Fig. 1 and Fig. 2 specific description embodiment:

The assembled lens imaging demonstrator for popular science teaching includes an outer frame 1 and an inner frame 2. The outer frame 1 is assembled from two outer panels 3, an outer bottom panel 4 and an outer rear panel 5. The outer rear panel A film 6 is arranged on the top, and a guide rail 7 is arranged on the outer bottom board; the inner frame is composed of two inner side boards 8, an inner bottom board 9 and an inner front board 10, and a lens is arranged on the inner front board 11. There is a guide groove 12 on the inner bottom plate, and the guide rail is inserted in the guide groove. The inner frame slides in the outer frame through the guiding action of the guide rail and the guide groove. The bottom of the outer frame is provided with a foot 13 .

In a preferred manner, the front ends of the legs are clamped on the outer rear panel and extend into the inside of the outer frame to form guide rails.

Preferably, there are three supporting legs, and the front ends of the three supporting legs are clamped on the outer bottom plate and extend into the inside of the outer frame to meet at one point.

Preferably, the side of the outer rear plate is provided with a snap-fit groove 14 opening downward, and the side of the outer side plate is connected to the outer rear plate through the snap-fit groove.

Preferably, a lens groove 15 is opened at the center of the inner front panel, and both sides of the inner front panel are connected to the inner panel through arc-shaped ear pieces 16 .

Preferably, the film is a frosted translucent film.

In actual use, the outer frame 1, the inner frame 2, and the feet are made of wood, the outer frame 1, the inner frame 2, and the feet are assembled by multiple pieces of wood, and the whole device is built with wood chips Yes, this kind of setting can greatly reduce the cost of the whole device. At the same time, it needs to be built when it is used, which can enhance the students' hands-on ability. can actually be combined.
