Abstract
The utility model relates to a Young's modulus instrument, and in particular relates to an optical lever device of a Young modulus instrument. The optical lever device comprises an optical lever mirror bracket and a staff-reading telescope; and the staff-reading telescope comprises a staff gauge parallel to the change direction of measured length and a telescope near the staff gauge. The optical lever device of the Young modulus instrument is characterized in that a laser is arranged on the telescope; a colour layer is arranged on the staff; and a coverage layer complementary with the colour layer in colour is arranged on the scale of the staff in a matched manner. The optical lever device of the Young's modulus instrument disclosed by the utility model has the following beneficial effects: laser is sent to the optical lever mirror bracket by the laser on the telescope; the telescope and a plane mirror on the optical lever mirror bracket can be rapidly adjusted to be at the same height according to the position of the laser on the optical lever mirror bracket; the colour layer different from the Young modulus instrument is arranged on the staff; the marked degree of the staff is increased; and the optical lever device of the Young modulus instrument is high in resolution ratio and very easy to find.
Description
(1) technical field
The utility model relates to a kind of Young modulus instrument, particularly a kind of optical lever device of Young modulus instrument.
(2) background technology
Young modulus is an important physical quantity that characterizes solid material character, it is one of important parameter that the selection of material need relate to often in the engineering design, need us to grasp by emphasis in learning process, in order to strengthen the study of this part, the student requires to measure Young modulus wiry with static pulling method, and the optical lever method can realize contactless measurement by magnification, and directly perceived, easy, precision is high, so often be used.This experiment utilize the optics amplification of optical lever realize to the small elongation Δ of tinsel L indirect measure corresponding Young modulus, the Young modulus instrument adjustment trouble of using in the experimentation, and the adjustment of its optical lever device of most importantly optical lever mirror holder and Telescope being formed, require telescope in the Telescope to be placed on minute surface from the optical lever mirror holder at sustained height, but the distance between the two generally is about 1.5-2.0m, so be difficult to regulate, the waste plenty of time, make the student can not utilize the limited class period to be practised fully.And the color of present Young modulus instrument and scale generally is silver color, is difficult for finding the scale reading of data in telescope, needs to improve.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, and a kind of optical lever device of easy to adjust, Young modulus instrument that the scale resolution is high is provided.
The utility model is achieved by the following technical solution:
A kind of optical lever device of Young modulus instrument, comprise optical lever mirror holder and Telescope, Telescope comprises scale parallel with measured length variations direction and the other telescope of chi, its special character is: laser instrument is set on the telescope, scale is provided with color layer, is furnished with the overlayer that becomes complementary colors with this color layer on the scale of scale.
Described laser instrument is positioned on centre position, telescopical side, and the laser instrument emitted laser is got to the optical lever mirror holder, is convenient to the adjustment of telescope and optical lever mirror holder.
Described optical lever mirror holder is the level crossing with three point foots, and the sideline of three point foots is an isoceles triangle shape, and the preceding two sharp sufficient edges of a knife and level crossing are in same plane, and the metacone foot is on the perpendicular bisector of the preceding two sharp sufficient edges of a knife.
The beneficial effects of the utility model are: the laser instrument on the telescope is got to laser on the optical lever mirror holder, according to the position of laser at the optical lever mirror holder, can quick adjustment to the level crossing of telescope and optical lever mirror holder be sustained height, the color layer different with Young modulus instrument is set on the scale, strengthen the eye-catching degree of scale, the resolution height is very easily looked for.

Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the structural representation of Telescope of the present utility model;
Accompanying drawing 2 is the structural representation of optical lever mirror holder of the present utility model;
Accompanying drawing 3 is the structural representation of Young modulus instrument;
Among the figure, 1 scale, 2 telescopes, 3 laser instruments, 4 point foots, 5 level crossings.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises optical lever mirror holder and Telescope, Telescope comprises scale 1 parallel with measured length variations direction and the other telescope 2 of chi, the optical lever mirror holder is the level crossing 5 with three point foots 4, the sideline of three point foots 4 is an isoceles triangle shape, preceding two point foot 4 edges of a knife and level crossing 5 are in same plane, metacone foot 4 is on the perpendicular bisector of preceding two point foots, 4 edges of a knife, laser instrument 3 is set on the telescope 2, scale 1 is provided with color layer, this color layer is different with Young modulus instrument color especially on every side, be furnished with overlayer on the scale of scale 1, this tectal color becomes complementary colors with color layer, very easily differentiates.Described laser instrument 3 is positioned on the centre position of telescope 2 sides, and laser instrument 3 emitted laser are got to the optical lever mirror holder, is convenient to the adjustment of telescope 2 and optical lever mirror holder.
