Description
Technical field
The utility model relates to a kind of displacement measuring device, be particularly related to and a kind ofly be used to reduce the heat distortion temperature analyzer under little load-up condition, when measuring the nonmetallic materials heat distortion temperature, because the elastic force of displacement measurement bar own wt, sounding rod inner spring and the friction force between sounding rod and the cover to influence of measurement error, improve the heat distortion temperature analyzer displacement measuring device of heat distortion temperature analyzer measuring accuracy.
Background technology
Nonmetallic materials are when doing heat distortion temperature mensuration, and the gross load that sample bears comprises the weight of pressure head, load beam, counterweight, weight tray and displacement measurement bar.Under the situation of little load, the impost beyond the counterweight often surpasses the load of regulation, causes measuring error.In these imposts, the accessory beyond the displacement measurement bar is because of being subjected to the restriction of structure or material, and its weight is difficult for reducing, so the mounting means of bit shift sounding rod plays key effect to reducing impost.The mounting means of existing displacement measurement bar is that dial gauge is installed in movably on the support, the end of displacement measurement bar directly be positioned over counterweight above.The elastic force and the friction force between sounding rod and the cover that there is own wt, the sounding rod inner spring of displacement measurement bar produce very big influence to the load precision, thereby cause error to measurement result, influence the problem of the measuring accuracy of heat distortion temperature analyzer.
Summary of the invention
The utility model overcomes deficiency of the prior art, the heat distortion temperature analyzer displacement measuring device that provides a kind of friction force of eliminating elastic force, sounding rod and the inner room of displacement measurement bar own wt, sounding rod inner spring that load is influenced.
In order to solve the problem of above-mentioned technology, the utility model is achieved through the following technical solutions: heat distortion temperature analyzer displacement measuring device, be that dial gauge is fixed on the support by set lever, sounding rod is connected with contact by screw thread, bascule is connected with support by the lever bearing pin, the center of the contact of bascule one end and the plane of the other end and lever bearing pin is on same surface level, support is connected with pole by set lever, pole is connected with specimen mounting by screw thread, pressure head is connected with load beam by screw thread, and load beam is connected with weight tray by screw thread.
