Problems solved by technology

The shapes of some existing rubber stoppers are as figure 1 , figure 1 The problem with the shape is that it can only be closed at one end of the ground hole. There are also some existing rubber plugs that can be closed at both ends, but the tail is small, difficult to disassemble, and easy to lose, which is easy to cause waste.

Abstract

The invention aims to provide a rubber plug for a compressor grounding hole, a grounding device and a compressor, and the rubber plug is of a cylindrical structure and sequentially comprises a first sealing part, a press-connect part and a second sealing part; the rubber plug is inserted into the compressor grounding hole from the first sealing part, and the diameter of the joint of the first sealing part and the press-connect part is larger than that of the press-connect part; the second sealing part comprises a first part connected with the press-connect part and a second part far away from the press-connect part, and the sections of the first part and the second part in the direction perpendicular to the axial direction of the rubber plug are in a step shape; the diameter of the first part is greater than that of the press-connect part; and the diameter of the second part is larger than that of the first part. The rubber plug is provided with the step-shaped second sealing part, so that the rubber plug is easier to detach from the grounding hole, and meanwhile, the end face of the grounding hole is better sealed, so that the grounding hole is effectively prevented from rusting in the transportation process.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a rubber plug used for a grounding hole of a compressor, a grounding device and a compressor. Background technique [0002] There are grounding holes on the liquid receiver bracket and foot of the rotor refrigeration compressor. During the transportation and storage of the compressor, the grounding holes cannot be rusted. At present, the grounding hole of the rotary compressor is sealed with a rubber plug, which is convenient for rust prevention. The shapes of some existing rubber stoppers are as figure 1 , figure 1 The problem with the shape is that it can only be closed at one end of the grounding hole. There are also some existing rubber plugs that can be closed at both ends, but the tail is small, difficult to disassemble, and easy to lose, which is easy to cause waste. Therefore, it is necessary to design a rubber plug sealing structure that can achieve sealing of both ends and...
