[0002] The fixed scroll is a component used to improve the performance of a scroll compressor. They are usually located at the inlet or outlet of the scroll compressor to change the direction and speed of the gas flow and form a rotating vortex flow.

[0003] A stationary scroll disk is arranged inside the scroll compressor. Generally speaking, the stationary scroll disk is fixed to the compressor casing by bolts or welding. However, during the operation of the stationary scroll disk, a certain degree of vibration will be generated. Therefore, when used for a long time, the positioning structure is easy to loosen, thereby affecting the overall operating stability of the stationary scroll disk, and the disassembly and assembly process is cumbersome during later maintenance.

[0004] Therefore, in order to solve the above problems, we need to propose a stationary scroll disk for use in a scroll compressor. Utility Model Content
