Anti-falling reflected image easily-available optical lever

Abstract

The present invention relates to a breakage-proof reflection image easily-available optical lever used in university physical laboratory. It is formed from foot stool, magnetic tiptoe, spring piece and lens, the lens is positioned in the centrobaric position of foot stool, and it adopts a drawing-inserting mounting mode, so that it can completely resove the difficult problem of that the optical lever can be easily fallen on the ground from measuring frame, and the lens can be conveniently replaced, and the lens size can be expanded, and the reflection image can be easily and quickly found out in the course of measurement.

Description

1. Technical field [0001] The invention belongs to the technical field of physical experiment instruments, and is an anti-drop reflective image easy-to-reach object by adjusting the installation position and installation method of the optical lever lens and changing its three toes to magnetic materials, so as to achieve the purpose of anti-drop and easy-to-obtain reflected image. Get light leverage. 2. Technical background [0002] At present, the eyeglasses of the known optical levers are all on the connecting line of the two front legs, and the rear legs are both thin and long. unstable structure. In the experimental operation, even a slight vibration will cause the light lever to fall and break. In addition, the lens of this light lever is located between the two front feet, and the distance between the two front feet is very limited, which limits the maximum size of the lens, making the search for the reflected image the biggest difficulty in the entire experimental op...

Problems solved by technology

Due to not realizing this, although the light lever keeps being broken and the reflective image is hard to find and annoying, there is no way to improve it.
