[0002] During the operation of the air compressor, the gas pressure changes greatly before and after being compressed by the compressor, and the pressure fluctuation during the gas compression process is also relatively large. The existing air compressors lack a voltage stabilizing and regulating device, resulting in abnormal gas pressure at the output end of the air compressor, which is not conducive to the subsequent use operation of the air compressor; the installation of the existing voltage stabilizing and regulating device is relatively troublesome and cannot achieve quick installation;

[0003] According to the Chinese patent publication number: CN218971386U, a voltage stabilizing and regulating device for an air compressor is disclosed. It can realize the preliminary fixation of the connecting ring and the mounting ring by clamping the sealing ring with the mounting groove, and achieve the quick installation work of the voltage stabilizing and regulating valve body and the air compressor. Rotate the mounting ring to align the through hole at its upper end with the through hole on the connecting ring, insert the eyebolt into the through hole between the connecting ring and the mounting ring, then align the eyebolt position of the eyebolt with the threaded hole position on the mounting plate, then insert the fixing bolt from one side of the mounting plate, pass through the eyebolt, and then fixedly connect it with the mounting plate, and then install the fixing nut on the eyebolt, thereby sealing and fixing the connecting ring and the mounting ring to prevent gas from leaking between the connecting ring and the mounting ring. Moreover, the device has a simple structure and convenient operation, and can quickly and stably fixedly connect the voltage stabilizing and regulating valve body and the air compressor;

[0004] In the technical solution, the connecting ring and the mounting ring are connected and fixed by a plurality of bolts, resulting in the need for specific wrench tools to twist and disassemble one by one during disassembly and assembly, thus affecting the disassembly and assembly efficiency of the voltage stabilizing and regulating valve body by personnel. For this reason, we propose a voltage stabilizing and regulating device for an air compressor. Content of the Utility Model
