Description
Technical field
The utility model relates to a kind of direct-injection type laser method and measures tinsel Young's modules instrument, belongs to Experiment of College Physics Instrument technology field.
Background technology
Tinsel Young modulus experiments of measuring is a more classical Experiment of College Physics, because it relates to the measuring method of small physical quantity, and is the combination of mechanics and Experiments of Optics method, and the meaning therefore offering this experiment is larger.
Adopt reflective mirror+add telescopical method to the measurement of tinsel Chroococcus minutus in original tinsel Young modulus experiments of measuring instrument, because of the observation that it is to natural light, the visibility of therefore testing is subject to certain restrictions, the more important thing is that experimental precision is subject to the restriction of telescopical optical accuracy and mechanical precision comparatively large, so experiment inevitably exists larger systematic error.
Utility model content
For the problems referred to above, the technical problems to be solved in the utility model is to provide the Young modulus experiments of measuring instrument that a kind of visibility is good, systematic error is little.
Direct-injection type laser method of the present utility model measures tinsel Young's modules instrument, and it comprises tinsel, tinsel chuck, miniature laser rifle, miniature laser rifle front fulcrum, miniature laser rifle rear fulcrum, miniature laser rifle platform, weight-hanger, counterweight, wire hangers, wire hangers bar, wire hangers base, wire hangers base screw, scale, scale bar, scale base, scale base screw, tinsel is suspended in wire hangers, and wire hangers is supported by wire hangers bar and wire hangers base, and wire hangers bar adjusts its verticality by wire hangers base screw, tinsel is fixed with tinsel chuck, weight-hanger is hung under tinsel, weight-hanger places counterweight, miniature laser rifle is shelved in miniature laser rifle platform and tinsel chuck by miniature laser rifle front fulcrum and miniature laser rifle rear fulcrum respectively, miniature laser rifle platform is fixed on wire hangers bar, scale is supported by scale bar and scale base, and the verticality of scale is adjusted by scale base screw.
As preferably, described tinsel chuck is marked with scale.
As preferably, described wire hangers base has on wire hangers bar center mark line, scale base and has scale surface location mark line.
The beneficial effects of the utility model are: small quantity wiry, and the amplification of the light sent by miniature laser rifle on scale, reaches the measurement effect that visibility is very large, and measuring error can control in less degree.
