Description

Technical Field

[0001] The utility model relates to the technical field of compressor cylinder seat supports, in particular to a support structure for a compressor cylinder seat. Background Art

[0002] The existing small reciprocating piston refrigeration compressor (household refrigerators and small freezers) consists of a shell, a core and a support part. The core and the shell are connected by the support part. The main function of the support part is to reduce vibration through the spring. Figure 4 As shown, the three-legged cylinder base 110 of the compressor includes three supporting legs 120. Figure 5 As shown, the support shell 130 of the tripod cylinder seat includes three support points 140. The tripod cylinder seat 110 is supported by pairing the three support legs 120 with the three support points 140. Figure 6 As shown, the four-legged cylinder base 150 of the compressor includes four supporting legs 160. Figure 7 The figure shows a support housing 2 170 for a four-legged cylinder base, which includes four support points 7 180. Four support legs 160 are paired with four support points 7 180 to support the four-legged cylinder base 150. Existing three-point or four-point supports are suitable for a three-legged cylinder base and a three-point supported housing, or a four-legged cylinder base and a four-point supported housing, respectively. However, a simple three-point support structure can lead to poor vibration and noise levels in the press. Instability during startup and shutdown can cause significant vibration of the machine core, resulting in start-up and shutdown noise. Furthermore, existing cylinder base support structures are not very versatile. Utility Model Content
