[0024] Example 1: As Figures 1-5 As shown, this utility model provides a technical solution: a high-strength corrosion-resistant fastener for offshore oil platforms, including a fastening component 1 and a connecting component 2. The connecting component 2 is provided with a sealing component 3. The fastening component 1 includes a fastening bolt 101, a nut 102 is threadedly connected to the outer side of the fastening bolt 101, an installation hole 104 is opened at one end of the fastening bolt 101, a fixing bolt 105 is threadedly connected to the inner side of the installation hole 104, a plurality of limiting grooves 103 are opened on the side of the nut 102, a limiting block 109 is installed inside the limiting groove 103, a connecting plate 108 is connected to the side of the limiting block 109, a plurality of springs 107 are distributed on the side of the connecting plate 108, a connecting member 106 is connected to one end of the spring 107, and one end of the connecting member 106 is connected to the fixing bolt 105.
[0025] In this embodiment, the nut 102 is threaded onto the outside of the fastening bolt 101, which helps ensure the stability of the fastening bolt 101. Then, the fixing bolt 105 is rotated so that it is threaded into the mounting hole 104. While rotating, the spring 107 is pulled and compressed. When the fixing bolt 105 rotates to a certain position, the spring 107 is released, causing it to extend and push the limiting block 109. This causes one end of the limiting block 109 to be installed inside the limiting groove 103. The connector 106 facilitates connection and ensures that the limiting block 109 effectively locks and limits the nut 102, preventing the nut 102 from loosening, enhancing the anti-loosening effect, and ensuring the stability of the nut 102's limiting of the fastening bolt 101, thereby ensuring the reliability of the fastening bolt 101.
