Technical Field

[0001] This utility model relates to the field of low-temperature constant temperature test baths, specifically a low-temperature constant temperature test bath. Background Technology

[0002] A cryogenic constant temperature test bath is an experimental device used to provide a precise temperature control environment, primarily for low-temperature testing and research in fields such as materials, electronics, and chemicals. It can maintain a constant temperature within a set low-temperature range (typically from -80°C to room temperature), ensuring that samples are tested under stable temperature conditions.

[0003] In existing technologies, personnel typically need to place the object to be tested into a low-temperature constant-temperature test chamber to perform the test.

[0004] However, when personnel directly place the object to be tested into the low-temperature constant temperature test chamber, there is still a lot of unused vertical space in the chamber when the object is small. In order to ensure the accuracy of the test, other objects cannot be stacked on the object to be tested. Only a small number of objects are tested at a time, which is inefficient. After the test is completed, personnel need to put their arms into the low-temperature constant temperature test chamber to take out the object, which is inconvenient for personnel to use.
