Abstract
Description

[0002] As a professional equipment used to simulate material performance testing in extreme high temperature environments, the high temperature test chamber's main function is to comprehensively evaluate the material's heat resistance, thermal expansion, thermal conductivity and other properties by controlling the temperature, pressure, humidity and other parameters in the environment. When testing samples with special shapes or requirements that cannot be placed directly on the bottom of the test chamber, a mounting rack is required to reduce the contact area between the sample and the inner wall of the test chamber or other components, and reduce the risk of heat conduction or contamination caused by contact, so as to ensure the accuracy of the final data.
[0003] The common way to fix the mounting frame is by bolts. However, if it is in a high temperature environment for a long time, thread slippage will occur and the mounting frame cannot be kept stable. In addition, the test in the high temperature test chamber is repetitive, which means that the bolts will repeatedly experience the process of heating up and cooling down. The bolts will expand and contract due to heat and cold, causing the bolts to get stuck or break directly. Therefore, we propose a new high temperature test chamber with mounting function to solve the above problems. Utility Model Content

In addition, the test of the high-temperature test chamber is repetitive, that is, the bolts will repeatedly experience a heating and cooling process, and the bolts will experience thermal expansion and contraction, resulting in the bolts being stuck or directly broken.
[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
