Description
Technical field
The utility model relates to a kind of device measuring object tiny length variable quantity, has a kind of electric adjustable nodal pattern optical lever for utilizing optical lever amplification principle to measure tiny length variable quantity.
Background technology
Pulling method is measured in the experiment of metal wire Yang's modulus, needs to measure tinsel Chroococcus minutus under a stretching force.Conventional measurement mechanism is made up of the telescope of the optical lever with plane mirror and band scale.This device utilizes optical lever amplification principle, by Chroococcus minutus wiry by specular light lever amplification, and observes the change through the rod reading of flat mirror reflects by telescope a long way off, indirectly measures Chroococcus minutus wiry thus.In instrument adjustment process, due to the reason such as light path is invisible, in telescope, not easily find the scale picture of being returned by the flat mirror reflects in optical lever, a people is needed to regulate the angle of level crossing at optical lever place, another people regulates telescope to observe a long way off, or a people repeatedly runs back and forth adjustment between optical lever and telescope, thus independently and easily cannot complete the adjustment of instrument, often need at substantial time conditioning instrumentation repeatedly, make troubles to actual measurement.
Summary of the invention
The technical problems to be solved in the utility model is the electric adjustable nodal pattern optical lever developing a kind of applicable one man operation facilitating instrument to adjust.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions:
A kind of electric adjustable nodal pattern optical lever, comprises level crossing, level crossing bearing, seat supports sheet, Metallic rod, level crossing shell; Described level crossing is located in level crossing shell, and level crossing shell vertical is fixed on level crossing bearing, and seat supports sheet is fixed on the bottom of level crossing bearing; One end of described Metallic rod is vertical with level crossing bearing to be connect, and the other end of Metallic rod is provided with the feet vertical with Metallic rod; Also comprise the level crossing drive unit be located in level crossing shell, and gauge tap; Described level crossing drive unit comprises driving circuit, micromachine, gearing; Described gauge tap, driving circuit, micromachine connect the rotation for controlling micromachine successively, and the rotating shaft connection gearing of micromachine, gearing and level crossing back side junction are used for control plane mirror and rotate up and down.
Described micromachine is bidirectional, dc motor.
Described gauge tap is wireless switching.
The utility model is owing to adopting above-mentioned design, experimenter only needs a people at telescope place by pressing gauge tap, carry out optical-lever mirror face tilt angle and telescopical adjustment simultaneously, avoid and frequently repeatedly regulate back and forth between optical lever and telescope, be conducive to simplifying experimental implementation, save experimental period.
