[0002] Fatigue-resistant fastening structural parts play a vital role in many fields. When subjected to cyclic loads or long-term use, fatigue-resistant fastening structural parts can maintain stable connection performance, thereby ensuring the integrity and stability of the overall structure, which is crucial to preventing structural failure and maintaining normal operation of equipment. Fatigue-resistant fastening structural parts can effectively disperse stress and reduce stress concentration, thereby improving the bearing capacity and fatigue resistance of the overall structure.

[0013] 1. For a fatigue-resistant fastening connection structural member of the present utility model, by providing fixing rods, protruding rods, sealing covers, first magnet rings, second magnet rings and clamping strips, the connecting member body and the workpiece can be limited by using four nuts and two screw rods.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope protected by the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution for a fatigue-resistant fastening connection structure member: Embodiment 1

[0022] As Figures 1-3 shown, a fatigue-resistant fastening connection structure member includes a connecting piece body 1, two screw rods 2 and four nuts 3. The two screw rods 2 are respectively arranged on both sides of the top of the connecting piece body 1. The four nuts 3 are respectively sleeved on the two ends of the two screw rods 2. Two positioning rings 4 are arranged outside the connecting piece body 1. Clamping strips 12 are arranged on both sides of the two positioning rings 4. Springs 13 are wound around the outside of the four clamping strips 12. Two fixing rods 5 are arranged on the outer wall of the connecting piece body 1. One ends of the two fixing rods 5 are provided with convex rods 6. One ends of the two convex rods 6 are respectively sleeved with L-shaped rods 7. One ends of the two L-shaped rods 7 are provided with sealing covers 8. One ends of the two sealing covers 8 are respectively sleeved with first magnet rings 9. Two second magnet rings 10 are arranged on the top of the connecting piece body 1. By relying on the two clamping strips 12 respectively engaging with the clamping grooves 14, the firmness of the installation of the convex rod 6 and the fixing rod 5 is ensured. The sealing cover 8 can wrap the external threads of the screw rod 2 exposed to the external environment, achieving the effects of sealing and anti-oxidation of the screw rod 2, avoiding the influence on the performance of the screw rod 2 after being affected by moisture, preventing the decline of the fatigue-resistant performance of the screw rod 2, and thus extending the service life of the connecting piece body 1. Embodiment 2

[0023] Based on Embodiment 1, as Figure 1 and Figure 4 shown, clamping grooves 14 are provided on both sides of the two convex rods 6. One ends of the four clamping strips 12 are respectively clamped and connected to both sides of the two fixing rods 5. The two L-shaped rods 7 are respectively movably sleeved on one end of the two convex rods 6. One ends of the two sealing caps 8 are respectively fixedly connected to one end of the two L-shaped rods 7. For a fatigue-resistant fastening connection structural member of the present utility model, by providing the pressing rod 11, the spring 13, the clamping groove 14 and the L-shaped rod 7, the convex rod 6 can telescopically move back and forth at one end of the L-shaped rod 7. After the sealing cap 8 is sealed with the top of the connecting member body 1, the convex rod 6 is pulled outwards, which is convenient for embedding the convex rod 6 into the inside of the fixing rod 5. One end of the spring 13 is fixed to the inner wall of the positioning ring 4.

[0024] Working principle: The fatigue-resistant fastening connection structure plays a crucial role in multiple fields. When the fatigue-resistant fastening connection structure is subjected to cyclic loads or long-term use, it can maintain stable connection performance, thus ensuring the integrity and stability of the overall structure. This is crucial for preventing structural failure and maintaining the normal operation of equipment. The fatigue-resistant fastening connection structure can effectively disperse stress and reduce stress concentration, thereby improving the bearing capacity and fatigue resistance of the overall structure. The fatigue-resistant fastening connection structure itself is equipped with bolts for positioning. The bolt is composed of a screw rod 2 and a nut 3. External threads are provided on the outer surface of the screw rod 2, and the external threads at the top are exposed to the external environment for a long time. The materials of some fatigue-resistant fastening connection structures may be sensitive to specific environmental conditions. In a humid environment, the performance of the screw rod 2 may be affected, resulting in a decrease in the fatigue resistance of the connection part and shortening the service life of the structure. At this time, the sealing cover 8 can be used to cover and seal the screw rod 2. The two nuts 3 and the two screw rods 2 can position the connecting part body 1 and the workpiece. The two sealing covers 8 are successively covered on the tops of the two screw rods 2. The first magnet ring 9 gradually approaches the second magnet ring 10, and the two are magnetically connected, thus ensuring the firm installation of the sealing cover 8. The convex rod 6 is successively moved towards the position close to the fixed rod 5. One end of the convex rod 6 gradually embeds into the interior of the fixed rod 5, and it relies on the two clamping strips 12 to engage with the card slots 14 respectively, ensuring the firm installation of the convex rod 6 and the fixed rod 5. The sealing cover 8 can wrap the external threads of the screw rod 2 exposed to the external environment, achieving the effects of sealing and antioxidation of the screw rod 2, avoiding the performance of the screw rod 2 being affected after being exposed to moisture, preventing the fatigue resistance of the screw rod 2 from decreasing, and thus extending the service life of the connecting part body 1. The convex rod 6 can stretch back and forth at one end of the L-shaped rod 7. After the sealing cover 8 is sealed with the top of the connecting part body 1, the convex rod 6 is pulled outwards, facilitating the embedding of the convex rod 6 into the interior of the fixed rod 5. One end of the spring 13 is fixed to the inner wall of the positioning ring 4. After the pressing rod 11 is pressed inwards, the spring 13 can be compressed and deformed, but the clamping strip 12 always remains inside the positioning ring 4, and the two will not separate, thus facilitating the use of the clamping strip 12 to limit the positioning ring 4, the fixed rod 5, and the convex rod 6.
