[0035] Working principle: When in use, first pick up the machine cover 109 and place it on the top of the compressor body 1, and press the machine cover 109 down, so that the convex strip 205 on the second sealing gasket 204 is embedded in the groove 201 on the first sealing gasket 2, and the pusher 107 is embedded in the inside of the connecting member 101, and the machine cover 109 is pressed down to make the top of the first sealing gasket 2 fit with the bottom of the second sealing gasket 204. When the machine cover 109 is pressed down, the pusher 107 slides downward inside the connecting member 101, and at the same time, the pusher 107 presses down the bottom plate 102, driving the first compound gasket 2 to move downward. The positioning spring 103 contracts, and when the bottom plate 102 is pressed down, the connecting column 104 is squeezed to slide outward, and the second return spring 106 is pulled to extend through the pull handle 105.

When the machine cover 109 is installed, the fixing member 110 can be picked up and put on the compressor body 1. The outer surface of the top and cover 109 is wrapped around the pusher 107 and the connecting member 101, and the first bolt 112 is embedded in the connecting plate 111, so that the fixing member 110 is fixed to the cover 109 and the compressor body 1. When the cover 109 needs to be disassembled, the first bolt 112 can be reversed to disengage it from the inside of the connecting plate 111, and then the fixing member 110 is removed, and then the handle 105 is pulled outward to drive the connecting column 104 to slide outward to disengage it from the inside of the connecting hole 108, and the cover 109 is pulled upward to make the pusher 1 07 is separated from the connecting piece 101, and then the machine cover 109 is completely disassembled. Through the structures such as the fixing piece 110 and the connecting piece 101, when the device is in use, not only the firm connection between the machine cover 109 and the compressor body 1 is ensured, but also this connection method can effectively prevent loosening caused by vibration and vibration, thereby improving the safety and stability of the machine cover 109. At the same time, through the design of the sealing gasket and the convex strip 205 and the groove 201, a good seal between the machine cover 109 and the compressor body 1 is ensured, thereby preventing the leakage of the internal medium of the compressor and improving the sealing of the compressor. During use, when the sealing gasket is damaged, the personnel can reverse the second bolt 202 to disengage the second bolt 202 from the first threaded hole 203, and then disassemble and replace the first sealing gasket 2, and then reverse the third bolt 206 to disengage the third bolt 206 from the second threaded hole 207, and then disassemble and replace the second sealing gasket 204. Through the design of the second bolt 202 and the third bolt 206 and other structures, the layered bolt structure can be used to make it relatively simple for personnel to replace and repair the sealing gasket, saving time and effort.
