[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0018] [Example 1]
[0019] Please combine Figure 1 and Figure 2As shown, a shear and torsion resistant hexagonal flange bolt includes a flange screw 1, a reinforcement 2 and a flange nut 3. The reinforcement 2 is embedded in the component a and is sleeved on the flange screw 1. The flange nut 3 is threadedly connected to the flange screw 1. The maximum outer diameter of the reinforcement 2 is smaller than the diameter of the flange nut 3, so that the flange screw 1 and the flange nut 3 can press the component a, so that the tensile stress of the entire flange bolt is borne by the flange screw 1 and the flange nut 3, the shear stress of the flange bolt is borne by the reinforcement 2, and the torsion and bending stress of the flange bolt are borne by the reinforcement rib 22, so that different stresses are borne by the corresponding part structure, the stress state of the flange bolt is improved, thereby increasing the service life of the flange bolt, ensuring the stability of the structure, and meeting the safety and reliable performance requirements.
[0020] Specifically, the flange screw 1 includes a screw 13, a nut 11 and a first flange 12, the nut 11 is fixed on the first flange 12, the screw 13 is fixed on the first flange 12, the flange nut 3 includes a second flange 31 and a nut 32, the second flange 31 is fixed to the end of the nut 32, when the flange nut 3 is threadedly connected and fixed with the flange screw 1, the component a is fixed between the flange nut 3 and the flange screw 1, so that the first flange 12 and the second flange 31 are deformed, making the locking more stable.
[0021] Specifically, the reinforcement member 2 includes a reinforcement ring 21 and reinforcement ribs 22. The reinforcement ribs 22 are equidistantly fixed on the outer surface of the reinforcement ring 21, thereby strengthening the connection with the component a, making the reinforcement member 2 more closely connected to the component a, thereby reducing the shear stress, torsion, and bending stress.
[0022] [Example 2]
[0023] Please combine Figure 2 and Figure 3As shown, a shear and torsion resistant hexagonal flange bolt includes a flange screw 1, a reinforcement 2, a flange nut 3, an elastic snap ring 4 and a locking nut 5. The reinforcement 2 is embedded in the component a, and the reinforcement 2 is sleeved on the flange screw 1. The flange nut 3 is threadedly connected to the flange screw 1, and the elastic snap ring 4 is clamped with the locking nut 5. The locking nut 5 is threadedly connected to the flange screw 1. The elastic snap ring 4 generates radial pressure under the tightening pressure, and further generates radial contraction deformation under the action of the radial pressure, so that the radial pressure between the elastic snap ring 4 and the flange screw 1 is increased, which greatly increases the locking nut 5 and the flange screw. The friction between 1 can effectively prevent the flange screw 1 from loosening dynamically, achieving a long-term anti-loosening effect. The maximum outer diameter of the reinforcement 2 is smaller than the diameter of the flange nut 3, so that the flange screw 1 and the flange nut 3 can press the component a, so that the tensile stress of the entire flange bolt is borne by the flange screw 1 and the flange nut 3, and the shear stress, torsion and bending stress of the flange bolt are borne by the reinforcement 2, so that different stresses are borne by the corresponding part structure, improving the stress state of the flange bolt, thereby increasing the service life of the flange bolt, ensuring the stability of the structure, and meeting the safety and reliable performance requirements.
[0024] Specifically, the flange screw 1 includes a screw 13, a nut 11 and a first flange 12, the nut 11 is fixed on the first flange 12, the nut 11 is fixed on the first flange 12, the flange nut 3 includes a second flange 31 and a nut 32, the second flange 31 is fixed to the end of the nut 32, when the flange nut 3 is threadedly connected and fixed with the flange screw 1, the component a is fixed between the flange nut 3 and the flange screw 1, so that the first flange 12 and the second flange 31 are deformed, making the locking more stable.
[0025] Specifically, the reinforcement member 2 includes a reinforcement ring 21 and reinforcement ribs 22. The reinforcement ribs 22 are equidistantly fixed on the outer surface of the reinforcement ring 21, thereby strengthening the connection with the component a, making the reinforcement member 2 more closely connected to the component a, thereby reducing the shear stress, torsion, and bending stress.
[0026] Specifically, the locking nut 5 includes a threaded connection end 51 and an engaging end 52, the threaded connection end 51 is threadedly connected to the flange screw 1, the elastic retaining ring 4 includes a limiting ring 41, a wedge ring 42 and a slot 43, the limiting ring 41 is fixed on the wedge ring 42, the slot 43 passes through the limiting ring 41 and the wedge ring 42, the wedge ring 42 abuts against the engaging end 52, the shape of the engaging end 52 matches the outer surface of the wedge ring 42, and the outer surface of the wedge ring 42 is provided with a conical slope.
[0027] Pressure is applied to the wedge ring 42 through the locking nut 5, so that the wedge ring 42 generates radial pressure under the tightening pressure, and further generates radial contraction deformation under the action of the radial pressure, so that the width of the slot 43 changes, and the radial pressure between the wedge ring 42 and the flange screw 1 increases, which greatly increases the friction between the wedge ring 42 and the flange screw 1 and prevents the wedge ring 42 from loosening; the contact surface between the cone of the wedge ring 42 and the cone of the locking nut 5 will generate greater friction under the tightening pressure, which prevents the locking nut 5 from loosening, so that the flange screw 1 can be effectively prevented from loosening under dynamic conditions, and a long-term anti-loosening effect can be achieved.
