Technical Field

[0001] The utility model relates to the field of nuts, and particularly relates to a pre-assembled sealed pallet self-locking nut. Background Art

[0002] A nut, also known as a screw cap, is a fixing tool with a hole in the center and internal threads on the inner side of the hole. It is often used in conjunction with screws of appropriate sizes to fix relevant joint parts. A nut is a part that is screwed together with a bolt or screw rod to play a fastening role. It is an essential component for all manufacturing machinery. According to different materials, it is divided into several major types such as carbon steel, stainless steel, and non-ferrous metals. Nuts are mostly hexagonal, and secondly square.

A corrugated sleeve 4 is fixedly connected to the center of the back of the mounting disc 6. A thread groove 5 is opened at the center of the inner cavity of the nut body 1. A first through groove 9 is opened in the inner cavity of the sealing gasket 3. A second through groove 10 is opened in the inner cavity of the connecting column 2. The inner cavities of the nut body 1, the sealing gasket 3 and the connecting column 2 are communicated. A circular groove is opened at the center of the back of the corrugated sleeve 4. The mounting disc 6 is a cavity structure with the front and the back communicating with the outside. The corrugated sleeve 4 and the mounting disc 6 are both communicated with the inner cavity of the nut body 1. Four positioning bolts 7 are symmetrically and threadedly connected to the periphery of the back of the mounting disc 6. The mounting disc 6 is threadedly connected to the back of the nut body 1 through the positioning bolts 7. Four extrusion blocks 8 are symmetrically and fixedly connected to the periphery of the back of the sealing gasket 3. The extrusion blocks 8 are in an "L" shape. Four extrusion grooves 11 are symmetrically opened at the center of the periphery of the connecting column 2. A fixing column 12 is fixedly connected to the inner cavity of the extrusion groove 11. An extrusion spring 13 is wound around the outer wall of the fixing column 12. The back of the extrusion spring 13 is fixedly connected to the back of the inner cavity of the extrusion groove 11. The front of the extrusion spring 13 is fixedly connected to the back of the extrusion block 8. A circular groove is opened in the back of the extrusion block 8.
