Description

Technical Field

[0001] The utility model relates to the technical field of temperature change test chambers, and more specifically to a rapid temperature change test chamber for cold and hot shock tests. Background Art

[0002] Thermal shock test chamber is an essential testing equipment for metal, plastic, rubber, electronic and other material industries. It is used to test the material structure or composite material to see how well it can withstand continuous extremely high and low temperatures in an instant, and to detect chemical changes or physical damage caused by thermal expansion and contraction of the sample in the shortest possible time.

[0003] After searching, the existing patent (publication number: CN216594634U) discloses a rapid temperature change test box for hot and cold shock tests. When in use, open the two box doors, lift the pull handle upward and then pull the placement piece outward to remove the placement piece, place the objects to be tested in the two placement pieces respectively, put the placement piece 207 back into the groove, close the box doors, start the refrigeration module and the heating module, and cool the object to be tested close to the refrigeration module through the refrigeration module, and heat the object to be tested close to the heating module through the heating module. When hot and cold shock is required, start the motor, and the motor drives the transmission part and the support part to rotate 180 degrees, so that the positions of the two placement pieces are interchanged. At this time, the objects to be tested in the two placement pieces are subjected to hot and cold shocks. However, the inventor discovered the following problems in the prior art during the process of realizing the present invention: when the above-mentioned temperature change test chamber is used, the material to be tested is placed in two placement pieces, and then the placement pieces are placed in the grooves for positioning. For such a placement situation, it is necessary to take the placement pieces when placing and taking out the test materials, which is inconvenient to operate. Moreover, the placement pieces are simply placed in the grooves for positioning. When the structure is rotated and adjusted, the placement pieces and the materials inside them are easily thrown out under the action of centrifugal force, thereby affecting the smooth progress of the subsequent temperature change time.
