Technical Field

[0001] The utility model relates to a test bench, in particular to a multi-station durability test bench for air conditioners, belonging to the technical field of air conditioner testing. Background Technique

[0002] An air conditioner is an air conditioner that adjusts temperature and humidity. A wall-mounted air conditioner is a unit used to provide processed air temperature changes in a spatial area. Its function is to adjust parameters such as the temperature, humidity, cleanliness, and air flow rate of the air in the room to meet the requirements of human comfort or technological processes. With the continuous development of air conditioner technology and the extensive expansion of application fields, the performance and durability requirements for air conditioner products are also increasing day by day.

[0003] In the current air conditioner durability test process, the common practice is to place the air conditioner on a special test bench and conduct the detection with the durability test mechanism equipped on the test bench. However, due to the relatively limited number of test stations and the fact that only one product can be detected at a time, this undoubtedly limits the detection efficiency. Secondly, since the sizes of different models of air conditioners vary, it is often difficult for the test mechanism to make corresponding adaptive adjustments according to actual needs, which limits the flexibility of the test during use and makes the test process have certain limitations.
