In addition, there is a certain distance between the telescope and the Young's modulus meter. During the operation, one person needs to increase or decrease the weight at the instrument, another person observes at the telescope, or one person runs back and forth between the instrument and the telescope, so it cannot be independent and convenient. to complete the experimental measurement

Embodiment Construction
[0014] Such as figure 1 , figure 2 As shown, the present invention includes a weight tray 6 and a stopper 4, the weight tray 6 is disc-shaped, and a stop rod 9 is fixedly connected to the center of the lower surface of the weight tray 6; the stopper 4 It is cylindrical, and the center of the limiter 4 has a through hole 5 for inserting the limit rod 9 , and the limiter 4 is placed at the center of the base 3 of the Young's modulus tester.
[0015] The limiting rod 9 is a cuboid, the through hole 5 is a rectangular through hole matched with the limiting rod 9, the height of the limiting rod 9 is less than the depth of the through hole 5, and the limiting rod 9 The length and width of the through hole 5 are respectively 2mm-10mm shorter than the length and width of the through hole 5, so that the stop rod 9 can move freely up and down in the through hole 5 and avoid turning back and forth.
[0016] The preferred technical solution is that the limiting rod 9 is a bar magn...

The invention discloses an anti-shake device for an integrated laser Young modulus determinator. The anti-shake device comprises a weight tray and a limiting device, wherein the weight tray is disc-shaped; a limiting rod is fixedly connected in the center of the lower surface of the weight tray; the limiting device is arranged at a center of a pedestal of the Young modulus experimental instrument and is a cylinder with a through hole in the center; the limiting rod is a cuboid; the through hole is a square through hole; the height of the limiting rod is less than the depth of the through hole; and the length and the width of the limiting rod are 2-10 mm shorter than the length and the width of the through hole respectively. The anti-shake device has the advantages of simple structure, practicability, convenience, low cost, obvious effect and contribution to improving the accuracy of experimental measurement.
Description
technical field [0001] The invention belongs to the field of physical experiment instruments, in particular to an anti-shaking device for an integrated laser Young's modulus measuring instrument. Background technique [0002] Young's modulus is an important physical parameter reflecting the mechanical properties of materials. The traditional stretching method to measure the Young's modulus of metals uses the principle of optical levers to amplify the tiny elongation of metal wires under the tension of weights through mirror optical levers and observe them through telescopes and scales placed far away. . However, in the actual operation process, it is difficult for the experimenter to find the scale image reflected by the optical lever plane mirror in the telescope, and it often takes a lot of time to adjust the instrument. In addition, there is a certain distance between the telescope and the Young's modulus instrument. During the operation, one person needs to increase or...
