Description

Technical Field

[0001] The utility model relates to the technical field of fixing structures, in particular to a fixing structure for an air-conditioning motor housing for airtightness detection. Background Art

[0002] The motor housing is one of the indispensable components of the motor. The airtightness of the motor housing is one of the important quality indicators of the motor housing. The existing airtightness detection devices cannot effectively seal the motor housing during the detection, and the operation is relatively complicated, increasing the labor intensity of the operators. To solve this problem.

[0003] Traditional fixing methods may rely on bolts and screws. Although this method is simple, it may not be applicable to all types of motor housings, especially those that need to be frequently disassembled and maintained. There are some problems with the fixing of the airtightness detection device for the motor housing, such as the fixing of the motor. During the fixing process, the disassembly is more troublesome and the process is cumbersome.

[0004] The accuracy of airtightness detection is directly related to the quality control of the motor housing. Some existing devices fill water into the motor housing to check whether there are water droplets leaking outside the motor housing, or put the motor housing into water and introduce high-pressure gas to check for leaks. Water detection wastes water resources, and the process is cumbersome and troublesome. Summary of the Utility Model
