Abstract

The invention discloses an optical bench, which includes a base and a plurality of fixing parts for installing experimental components, the base is provided with a connection surface extending along a first direction, and the base is provided with a connection surface along the connection surface. For the first scale, a plurality of first plug-in parts are evenly spaced on the connecting surface, and second plug-in parts are arranged on the fixing part, and the first plug-in parts of each fixing part can be plugged with any second plug-in parts Cooperate; one end of the transmission rod on the outside of the housing is connected with a knob, the transmission rod is connected to a gear on the inside of the housing, the gear and the rack are meshed, and the fixed block is fixedly connected to the rack; the housing is surrounded by a knob As for the second scale, the distance between two adjacent first plug joints is not greater than the distance that the transmission rod rotates to drive the fixed block to move, and the first scale is an order of magnitude larger than the second scale. The optical bench provided by the present invention is not only easy to rotate at a constant speed when the knob connected to the gear is controlled, but also can be rotated to the target position more conveniently at one time.

Description

technical field

[0001] The invention relates to physical experiment technology, in particular to an optical bench. Background technique

[0002] Middle school physics experiments involve many optical experiments, such as convex lens experiment, concave lens experiment, small hole imaging experiment, etc. The experimental equipment of these optical experiments includes optical bench, and each optical experimental component is installed on the optical bench to complete the corresponding experiment.

[0003] The inventor found in the usual study and research that in the prior art, the optical bench includes a base, and a slide rail is arranged on the base, and a plurality of fixing parts for fixing the optical experiment elements are slidably connected to the slide rail. During the experiment, the Different experimental components are fixed to each fixture one by one, and after the light source is turned on, the fixtures are slid back and forth on the slide rail to obtain the ...
