Description

Technical Field

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

[0002] The existing small reciprocating piston refrigeration compressor (household refrigerator and small freezer) consists of a shell, a core and a support part, wherein the core and the shell are connected by the support part, and the main function of the support part is to reduce vibration through springs. Figure 4 As shown, a three-legged cylinder base 110 of a compressor includes three supporting legs 120. Figure 5 As shown, the supporting shell 130 of the tripod cylinder seat includes three supporting points 140. The tripod cylinder seat 110 is supported by pairing the three supporting legs 120 with the three supporting points 140. Figure 6 As shown, the four-legged cylinder base 150 of the compressor includes four supporting legs 160. Figure 7 As shown, the supporting shell 2 170 of the four-legged cylinder seat includes four supporting points 7 180, and the four-legged cylinder seat 150 is supported by pairing the four supporting legs 4 160 with the four supporting points 7 180. That is, the existing three-point support or four-point support is respectively suitable for the three-legged cylinder seat and the three-point supporting shell, and the four-legged cylinder seat and the four-point supporting shell. Due to the simple three-point support structure, the vibration and noise of the press are not good, and the instability during start-up and shutdown will cause the core to shake greatly, thereby generating the start-stop shell collision noise problem. At the same time, the existing cylinder seat support structure is not very versatile. Summary of the invention

[0005] Furthermore, the bottom surface of the lower shell is provided with a base connection portion for connecting to the lower base, one end of the outer side surface of the lower shell is provided with an electrical connection hole for connecting to an electrical component, and the outer side surface of the lower shell is also provided with a plurality of pipe holes.

[0006] Furthermore, a screw connection hole is provided in the middle of the connecting bracket, and the connecting bracket is connected to the bottom of the tripod cylinder seat by screws.

[0007] Furthermore, the first supporting point, the second supporting point, the third supporting point, the fourth supporting point, and the fifth supporting point are all elliptical planes.

[0008] Furthermore, the inner wall of the lower shell is provided with an arc-shaped guide wall surface connected to the first support point, the second support point, the third support point, the fourth support point, and the fifth support point.

[0009] Beneficial effects of the present invention: The support structure of the present application is suitable for three-point support, four-point support and five-point support of the compressor cylinder seat, and can meet the use of tripod cylinder seats and four-leg cylinder seats at the same time, with strong versatility. At the same time, after the tripod cylinder seat is connected to the connecting bracket, the five-point support of the tripod cylinder seat can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS
