Abstract
The utility model relates to a lens focusing experimental facility for physics teaching in universities and specifically to an electric lens focusing experimental facility for physics teaching in universities. The utility model resolves a problem that it is a waste of time and easy to cause errors to manually adjust the positions of a light source, a lens, and a focusing plate and the distances among the light source, the lens, and the focusing plate so as to cause inaccurate experimental results in lens focusing experiments. One end of a first guide rail is detachably connected with one end of a second guide rail through a hinge pin. The light source is installed on a light source pedestal which is in sliding connection with the first guide rail. The focusing plate is installed on a focusing plate pedestal which is sliding connection with the second guide rail. The lens is installed on the top end face of the hinge pin. A first linear motor is installed on the light source pedestal. A second linear motor is installed on the focusing plate pedestal. The electric lens focusing experimental facility is used in optical experiments in physics teaching in universities.
Description
Technical field
The utility model relates to a kind of college physics teaching lens focus experimental provision, is specifically related to a kind of college physics teaching electrodynamic type lens focus experimental provision.
Background technology
The lens focus experiment is a requisite experiment subject in college physics teaching, in the lens focus experiment, the faculty needs the distance between frequent manual adjustments light source, lens, focusing board three, adjustment process extremely bothers, also lose time, and guarantee light source, lens, focusing board three on same straight line,, in case the position between light source, lens, focusing board three is offset, will cause experimental result inaccurate.
The utility model content
The utility model is for solving in the lens focus experiment position and the distance that adopts between manual shift light source, lens, focusing board, lose time, and occur that easily error causes testing the inaccurate problem of structure, and then propose a kind of college physics teaching electrodynamic type lens focus experimental provision.
the utility model is to address the above problem the technical scheme of taking to be: the utility model comprises light source, lens and focusing board, the utility model also comprises the first guide rail, the second guide rail, light source base, the focusing board base, the first linear electric motors, the second linear electric motors and bearing pin, the first guide rail and the second guide rail are the yi word pattern setting, one end of the first guide rail and an end of the second guide rail removably connect by bearing pin, light source is arranged on light source base, light source base and the first guide rail are slidably connected, focusing board is arranged on the focusing board base, focusing board base and the second guide rail are slidably connected, lens are installed on the upper surface of bearing pin, the first linear electric motors are arranged on light source base, the first linear electric motors driving light source base is along the first guide rail traveling priority, the second linear electric motors are installed on the focusing board base, the second linear electric motors drive the focusing board base along the second guide rail traveling priority.
The beneficial effects of the utility model are: the utility model can make faculty position and distance between remote adjusting light source, lens, focusing board three, avoided the time of manual shift waste, can only be along the first guide rail and the second guide rail traveling priority due to light source and focusing board, therefore eliminated light source and focusing board and has produced to be offset in moving process and cause the inaccurate problem of experimental result; Two base for supporting have increased the contact area of the first guide rail and the second guide rail and surface level, have increased the stability of the device of experiment, have avoided the experimental result that causes because experimental provision self is unstable to produce error; The first guide rail and the second guide rail adopt and removably connect, and when not using the utility model, have reduced floor area of the present utility model; The utility model is simple in structure, and is easy to operate, safeguards simple and easy.
