Example 1
Referring to fig. 1, 2 and 3, a preferred embodiment of the scroll compressor for the air conditioner of the present invention is a scroll compressor using a pin-and-ring anti-rotation mechanism. The anti-rotation mechanism comprises a static vortex disk 1, a movable vortex disk 2, a circular ring 3, a cylindrical pin 4, a movable vortex disk support seat 5 and a crankshaft. The fixed scroll 1 is fixed on the compressor end cover or the cylinder body through a positioning pin. The movable scroll 2 is supported by a driven scroll supporting seat 5, keeps the phase constant with the fixed scroll 1 at 180 degrees and is driven by a crankshaft 6. Six cylindrical pin holes 501 are uniformly arranged on the movable scroll plate support seat 5 along the circumference. Six annular holes 201 are arranged on the movable scroll 2 corresponding to the positions of the cylindrical pin holes 501 of the movable scroll support seat 5. The annular holes 201 are also evenly distributed along the circumference of the orbiting scroll 2. The pitch circles of the six cylindrical pin holes 501 have the same diameter as the pitch circles of the six annular holes 201. On each ring hole 201, lug holes 202 as oil grooves are uniformly provided along the circumference of the ring hole 201.
The cylindrical pins 4 correspond to the cylindrical pin holes 501 on the movable scroll support seat 5 one by one, and the cylindrical pins 4 are pressed into the cylindrical pin holes 501 and are in interference fit with the cylindrical pin holes. The circular rings 3 correspond to the circular holes 201 on the movable scroll 2 one by one, and the circular rings 3 are arranged in the circular holes 201 on the movable scroll 2 and are in micro-clearance fit with the circular holes.
When the phase difference of 180 degrees between the movable scroll 2 and the fixed scroll 1 is ensured, the cylindrical pins 4 are respectively arranged in the inner ring of the circular ring 3. At this time, six sets of pin ring mechanisms are formed.

The distance between the center of the round handle 7 and the center of the eccentric hole on the round handle 7 is the same as the radius of gyration. The round handles 7 with eccentric holes are in one-to-one correspondence with the annular holes on the movable scroll disk 2. After the round handle 7 is arranged in the annular hole, the round handle and the annular hole form micro clearance fit. One end of the cylindrical pin 4 is pressed into the cylindrical pin hole 501, and the other end is inserted into the eccentric hole of the round handle 7, so that six groups of pin handle mechanisms are formed. Six cylindrical pin holes 501 are uniformly arranged on the movable scroll support base 5 along the circumference. Under the drive of the crankshaft 6, each group of cylindrical pins 4 and the eccentric hole passing through the round handle 7 limit the rotation of the movable scroll 2, thereby ensuring that the movable scroll 2 does rotary translation around the fixed scroll 1 in a determined phase.
In this embodiment, the design of lug hole 202 is added on the annular ring 201, the oil pressure buffering is utilized to effectively reduce the impact noise of the round handle 7 and the annular ring 201, the oil-rich lubrication reduces the motion friction noise of the round handle 7 and the annular ring 201, and the NVH index is improved.
