In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0020] like Figures 1 to 3 As shown, the utility model discloses a rust-proof nylon bolt structure, including a body 1, the body 1 including a screw rod 101 and a nut 102, the screw rod 101 and the nut 102 are integrally arranged, the outer periphery of the screw rod 101 is provided with a thread for connection, a reinforcement groove 2 is provided in the body 1, a reinforcement rod 3 is fixed in the reinforcement groove 2, the reinforcement rod 3 is adapted to the shape of the reinforcement groove 2, and the stress that the body 1 can withstand is increased by installing the reinforcement rod 3 in the body 1 to improve its own strength, so that the bolt made of nylon material has excellent rust-proof performance and can improve its own strength, thereby improving the stability of long-term use, and by arranging the reinforcement groove 2 at the center position of the body 1, and the reinforcement rod 3 is adapted to the shape of the reinforcement groove 2, the reinforcement rod 3 can be stably fixed in the reinforcement groove 2, and the support force on the body 1 is made more uniform, wherein the reinforcement rod 3 should be made of high-stress material, so that the strength of the bolt itself can be effectively improved.

[0021] In this embodiment, a spacing is left between the reinforcing rod 3 and the notch of the reinforcing groove 2, and a shielding cover 4 is provided at the notch of the reinforcing groove 2. After the reinforcing rod 3 is installed in the reinforcing groove 2, the reinforcing groove 2 can be covered by the shielding cover 4 to prevent the reinforcing rod 3 from being directly exposed to the outside, and the color of the shielding cover 4 can be set to be consistent with the color of the main body 1, so as to visually improve the integrity of the main body 1 and make the whole more beautiful.

[0022] In this embodiment, a protruding connecting flange 41 is provided at the bottom of the shielding cover 4, and the outer wall of the connecting flange 41 abuts against the peripheral wall of the reinforcement groove 2.
