[0020] like Figures 1 to 7As shown, a high-strength anti-loosening fastening bolt includes a main body stable fitting seat 1 projected as an isosceles trapezoid in the front-to-back direction, and an integrally formed transition support connection seat 2 is provided at the lower end center position of the main body stable fitting seat 1, which ensures the structural matching strength of the connection position. An integrally formed cylindrical main body fastening connection column 3 is provided at the lower end center position of the transition support connection seat 2, and a fastening matching thread groove is provided on the outer cylindrical surface of the main body fastening connection column 3, which is the main body fastening connection structure of the bolt. The lower end surface of the main body stable fitting seat 1 is located on the left and right sides of the transition support connection seat 2, and is respectively provided with anti-skid safety matching grooves 4 that are evenly distributed front and back and completely penetrate the outer sides in the left and right directions, and the combination surface between the fastening position and the matching position has a reliable anti-skid effect. The lower end surface of the main body stable matching seat 1 is located on the left and right sides of the transition support connecting seat 2, and is respectively provided with an anti-loosening combination connecting groove 5 with a central axis in the front-to-back direction, which can be matched with anti-loosening glue for filling and matching, so that the anti-loosening firmness of the internal fastening position is better. This position can also be matched with the mechanical component for limiting matching as needed, so that the position after the overall fastening is better and has a reliable anti-loosening matching effect. The depth of the anti-loosening combination connecting groove 5 is greater than the depth of the anti-slip safety matching groove 4. The anti-loosening combination connecting groove 5 completely penetrates the front-to-back direction of the main body stable matching seat 1, ensuring the combined strength during matching and making the anti-loosening strength more reliable. It sets an isosceles trapezoidal structure at the end of the bolt and cooperates with the filter support connecting seat to ensure the structural strength of the end position. Its end can have a reliable anti-slip effect after fastening by setting an anti-slip matching layer. Then, through the transverse anti-loosening combination connecting groove, it can be matched with anti-loosening glue for filling and matching during use, so that the anti-loosening stability of the overall fastening position is better, the connection matching strength is higher, the safety during use is more reliable, and the durability is stronger.
[0021] Preferably, the width of the transition support connecting seat 2 in the front-to-back direction is the same as the width of the main body stable matching seat 1 in the front-to-back direction, so that the overall structural support strength is better and the service life is longer during use.
[0022] Preferably, an arc-shaped protective safety structural surface is provided at the outer edge of the transition support connecting seat 2, which provides better safety during cooperation and avoids the existence of sharp-angle structures.
[0023] Preferably, the cross-section of the anti-slip safety matching groove 4 is a V-shaped structure, and the cross-section of the anti-loosening combined connecting groove 5 is an arc-shaped structure, which is more convenient during production and easier to process during production.
[0024] Preferably, a conical guide mating surface is provided in the front and rear directions of the anti-loosening combined connecting groove 5, respectively, so that the anti-loosening glue can be filled smoothly and flow into the interior more efficiently.
