Description

Technical Field

[0001] The utility model relates to the technical field of temperature testing, and more specifically, to a temperature shock testing box. Background Art

[0002] High and low temperature impact test chamber can be used to test the degree to which materials or composite materials can withstand continuous extremely high and low temperature environments in an instant, and test the chemical changes or physical damage caused by thermal expansion and contraction in the shortest time. The test objects can also be electronic and electrical components, automation components, communication components, electronic chips, auto parts, PCB substrates, metals, chemical materials, polymer materials, plastics, etc. High and low temperature impact test chambers are widely used in the fields of national defense industry, aviation and household appliance industry. For example, a temperature impact test chamber disclosed in the prior art publication number (CN218444756U) When the placement rack is adjusted in position, the placement rack first enters the interior of the sealing sleeve, and when entering the cold chamber, the placement rack drives the lower sealing plate to rise, so that the lower sealing plate seals the lower end of the sealing sleeve, and when the placement rack continues to rise, the second spring is stretched, and when entering the hot chamber, the upper sealing plate seals the upper end of the sealing sleeve, and the placement rack continues to descend, so that the first spring is stretched, which is convenient for sealing the sealing sleeve, and when the sleeve is connected, the sealing sleeve is driven to rise and fall through the lifting plate by the electric telescopic rod, thereby avoiding the sealing sleeve from blocking the sample on the placement rack and improving the experimental effect.

[0003] When the above device is in use, it is convenient to place the sample, and through the sealing sleeve, when the sample is converted from hot to cold, convection of air inside the cold chamber and the hot chamber is avoided, thereby avoiding heat neutralization and the need for re-cooling or heating, thereby reducing energy consumption. However, when the spring tightens the sealing plate and the sealing component to seal, the sealing effect is poor. At the same time, the lower sealing plate cannot effectively seal the sealing component when it rises, which easily causes the temperature inside the two chambers to flow cross-currently.
