In the drawings: fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

The physically adjustable optical experiment platform, as shown in fig. 1, includes a transparent box 12, a first stepping motor 13 and a support frame 20 are installed inside the transparent box 12, an output shaft of the first stepping motor 13 is in a horizontal state, a rotating base 15 is installed on the output shaft of the first stepping motor 13, a laser emission module 16 is connected to one side of the rotating base 15, a transparent triangular prism 17 is installed on the upper portion of the support frame 20, an aerosol 19 is filled inside the transparent box 12, and a protractor 14 is connected to one side of a housing of the first stepping motor 13.

The utility model discloses install laser emission module 16 inside transparent box 12 to the laser that makes laser emission module 16 produce need not to pass transparent box 12 and just can directly get into the aerosol, thereby can make the more accurate demonstration light path of aerosol. The utility model discloses combine electric putter 11 and first step motor 13, can realize laser emission module 16's angle modulation to make things convenient for laser emission module 16 to follow different positions to transparent triangular prism 17 transmission laser, thereby make things convenient for the student to survey the refraction that transparent triangular prism 17 produced to different angle incident laser.

Material selection and feasibility analysis of specific implementation: the sample actually manufactured is implemented by taking the specification attached drawing as a drawing according to the proportion and the matching mode of each part in the specification attached drawing, the connection is a common connection mode such as strong adhesive connection, welding, riveting, flange connection, integrated connection, detachable connection and the like, and the corresponding connection mode, the thickness and the strength of the connection point can be selected according to the actual connection strength without creativity during actual manufacturing. First step motor 13 and second step motor 18 all adopt the step motor that 3d printer used and the step motor controlling means who corresponds, the step motor that 3d printer used can carry out rotation angle's ration rotation, reach the technological effect of this application, perhaps this application also can only utilize step motor's rotation to realize laser emission module 16's angle modulation, thereby make things convenient for laser emission module 16 to follow different positions to transparent triangular prism 17 transmission laser, thereby make things convenient for the student to observe the refraction that transparent triangular prism 17 produced to different angle incident laser.
