[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0019] like Figure 1-4As shown, the utility model discloses an anti-loosening nut, including a nut A1, on which an anti-loosening assembly is provided, the anti-loosening assembly including a nut B2 located above the nut A1, a spring 3 fixedly arranged below the nut B2, a rotating ring 4 fixedly arranged below the spring 3, and a pressure pad 5 detachably arranged below the nut A1, a rotating groove 6 is provided on the top wall of the nut A1, the rotating ring 4 is inserted into the rotating groove 6 and is rotatably connected to the nut A1, and a plurality of ratchets 7 are fixedly arranged below the pressure pad 5. When the present invention is used, firstly, the bolt is passed through the mounting hole of the part to be locked and extended out of the part to be locked, and the nut A1 and the nut B2 are screwed into the extended part of the bolt at the same time, and the nut A1 and the nut B2 are rotated so that the pressure pad 5 contacts and connects with the part to be locked, and the locking nut A1 causes the ratchet 7 to be embedded in the interior of the part to be locked, thereby fixing the nut A1; the rotation of the nut B2 drives the spring 3 and the rotating ring 4 to rotate, so that the spring 3 is continuously compressed. After the nut B2 is locked, the spring 3 will simultaneously apply elastic force to the nut A1 and the nut B2, so that the threads of the nut A1 and the nut B2 are pressed against the threads of the bolt, thereby preventing the nut A1 and the nut B2 from loosening; the stud 10 After being screwed into the screw hole 11 and threadedly connected with the nut A1, after locking the stud 10, the stud 10 will be pressed on the thread of the bolt to prevent the nut A1 from rotating, thereby further preventing the nut A1 from loosening; use pliers to clamp the nut B2 and make the clamping groove face the pliers, clamp the pliers to cause the nut B2 to deform at the clamping groove, so that the thread of the nut B2 is clamped with the thread of the bolt, thereby further preventing the nut B2 from loosening; in summary, the utility model has the beneficial effect of preventing the nut from loosening, and solves the problem that when the nut is in a high-vibration working environment, the nut will be subjected to long-term vibration, which may easily cause the nut to loosen or even fall off, resulting in a poor fastening effect.
[0020] Preferably, an anti-slip ring 8 is fixedly provided below the rotating ring 4. The diameter of the anti-slip ring 8 is larger than that of the rotating ring 4. An anti-slip groove 9 matching the anti-slip ring 8 is provided on the bottom wall of the rotating groove 6. The anti-slip ring 8 is located inside the anti-slip groove 9 and is rotatably connected to the nut A1. Since the diameter of the anti-slip ring 8 is larger than that of the rotating ring 4, the anti-slip ring 8 is located inside the anti-slip groove 9 and is rotatably connected to the nut A1. When the nut A1 and the nut B2 are not in use, the anti-slip ring 8 will be stuck inside the anti-slip groove 9, thereby preventing the rotating ring 4 from falling off.
[0021] Preferably, the anti-loosening assembly further includes a stud 10. A screw hole 11 is formed on the side wall of the nut A1 and extends through the inner hole of the nut A1. The stud 10 is screwed into the screw hole 11 and threadedly connected to the nut A1. Since the stud 10 is screwed into the screw hole 11 and threadedly connected to the nut A1, after the stud 10 is tightened, it will press against the threads of the bolt, preventing the nut A1 from rotating, thereby further preventing the nut A1 from loosening.
[0022] Preferably, a mounting groove 12 is defined on the bottom wall of the nut A1. A magnetic ring A13 is fixedly mounted within the mounting groove 12. A magnetic ring B14 is fixedly mounted above the pressure pad 5. The magnetic ring B14 is inserted into the mounting groove 12 and magnetically connected to the magnetic ring A13. The magnetic connection between the magnetic ring B14 and the mounting groove 12 facilitates assembly and disassembly of the pressure pad 5. When damage to the surface of the part to be tightened is unacceptable, the pressure pad 5 can be removed from the nut A1.
[0023] Preferably, an elastic sleeve 15 is provided on the outside of the spring 3, and the upper and lower ends of the elastic sleeve 15 are fixedly connected to the nut B2 and the nut A1 respectively. Since the elastic sleeve 15 is provided on the outside of the spring 3, it serves to block external impurities. When the spring 3 is compressed, the elastic sleeve 15 will deform accordingly, without affecting the compression of the spring 3.
[0024] Preferably, a pressing groove 16 is formed on the side wall of the nut B2 and extends through the inner hole of the nut B2. Since the pressing groove 16 is formed on the side wall of the nut B2 and extends through the inner hole of the nut B2, when the nut B2 is clamped with pliers with the pressing groove facing the pliers, the nut B2 is deformed at the pressing groove by tightening the pliers, and the threads of the nut B2 are clamped to the threads of the bolt, which further prevents the nut B2 from loosening.
[0025] Preferably, the stud 10 is fixedly provided with an elastic pad 17 on the side facing the inner hole of the nut A1. Since the stud 10 is fixedly provided with the elastic pad 17 on the side facing the inner hole of the nut A1, it plays a role in preventing the bolt thread from being crushed.
[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
