Description

Technical Field

[0001] The utility model relates to the technical field of experimental teaching appliances, and particularly relates to an adjustable parallel light source demonstration device. Background Art

[0002] Chinese Patent CN202123396405.6 discloses a light-emitting component for a laser box. The adopted technical solution is that it includes a housing and a flip cover connected to the housing. An optical output channel is arranged inside the housing, and a light outlet is formed in the flip cover. A beam splitter is arranged on the first surface of the flip cover, and the beam splitter is used to disperse the light source into a linear light source. The flip cover can rotate so that the beam splitter is aligned with the optical output channel or the beam splitter is misaligned with the optical output channel. The above technical solution can realize the switching demonstration of point and linear light sources, but there are still the following problems. When the flip cover is flipped, the beam splitter lacks end limits and is easy to slide off the flip cover, resulting in the loss of the beam splitter and the inability to conduct normal teaching demonstrations, which has certain drawbacks.

[0003] Chinese Patent CN202120053165.0 discloses a point and linear light source switching type laser box. The adopted technical solution is that it includes a box body. A laser emitter for emitting laser light is arranged inside the box body. The box body is provided with at least one light-emitting component. An optical output channel is arranged inside the light-emitting component. The light-emitting component is connected with a sliding cover. A light outlet is formed in the sliding cover. A beam splitter is arranged on the first side of the sliding cover, and the beam splitter is used to disperse the light source into a linear light source. The sliding cover can move relative to the light-emitting component so that the beam splitter is aligned with the optical output channel or the beam splitter and the optical output channel are misaligned. The above technical solution can realize the switching demonstration of point and linear light sources, but there are still the following problems. When switching the light source, the demonstrator needs to slide the sliding cover upward. The sliding cover and the light-emitting component are limited by a limiting block. When the force is too large or the limiting block is worn after sliding the sliding cover multiple times, the sliding cover is easily separated from the light-emitting component, thus affecting normal teaching demonstrations, which has certain drawbacks.

[0004] In summary, an adjustable parallel light source demonstration device is needed to solve the problems that when switching between point and linear light sources, the beam splitter is avoided from detaching and being lost, and parts are not detached due to excessive force, which affects normal teaching demonstrations.
