Technical Field

[0001] The utility model relates to the technical field of aging test chambers, in particular to a high-temperature aging test chamber. Background Art

[0002] High temperature test chamber is an essential test equipment in the fields of aviation, automobile, home appliances, scientific research, etc. It is used to test and determine the parameters and performance of electrical, electronic and other products and materials after the temperature environment changes in high temperature or constant tests. High temperature aging test chamber is also widely used in industry, but some existing high temperature aging test chambers are easy to cause the risk of burns to the staff when in use, so we need a more practical high temperature aging test chamber.

[0003] The defect of a high-temperature aging test box in the prior art is: Patent document CN216654585U discloses "The utility model discloses a high-temperature aging test box, including a base, the top of the base is fixedly connected to a box body, the inner wall of the box body is fixedly connected to a heat-insulating liner, the inner bottom of the heat-insulating liner is provided with a groove, the inside of the groove is penetrated by a rotating shaft, the top of the rotating shaft is fixedly connected to a bracket, and the top of the bracket is slidably connected to a placement rack. In the utility model, the rotation of the driving motor drives the placement rack to rotate and the air delivery mechanism to operate, so that the hot air can be evenly blown to the outer surface of the experimental body, so that the outer surface of the experimental body can be evenly heated, thereby greatly increasing the test accuracy, the operation of the exhaust mechanism can extract the internal hot air outward when the sealed door is opened, thereby avoiding the situation where the high-temperature gas is discharged from the sealed door and causes burns, and the placement rack can be slid so that the placement rack slides out of the box body, so that there is no need to operate inside the box body, which increases safety."

[0004] However, although the above device can achieve high-temperature heating and aging of the experiment when in use, it is more complicated to take out the internal experimental body after use. Since the device needs to be heated at high temperature, the temperature inside the device is relatively high. It takes a long time to cool the experimental body when taking out the experimental body. At the same time, there are certain problems in the above device using a spring to pop out the storage plate to take out the experimental body. Because the spring pops out at a fast speed and the object has inertia, it is easy for the aged experimental body to be unstable when it pops out, thereby colliding with the inside of the device and causing damage. Therefore, the equipment still has certain shortcomings and needs further improvement. Utility Model Content
