[0003] Nuts currently on the market have the following problems in actual use:

[0004] 1. In practical use, traditional nuts are installed by rotating with threads. When the device installed on the nut vibrates during use, the nut may loosen, resulting in poor stability during use.

[0005] 2. During use, most nuts come into direct contact with the installation location and are secured by friction. Over time, wear may occur between the nut and the installation location, resulting in poor protection during use. Utility Model Content

[0006] The purpose of this utility model is to provide a nut structure with an anti-loosening structure to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A nut structure with an anti-loosening structure includes a forward thread nut and a reverse thread nut. The forward thread nut has a rotating assembly inside, which protects an annular groove, a rotating ring, and a fixing rod. The forward thread nut has an annular groove inside, and a rotating ring is sleeved inside the annular groove. A fixing rod is welded to the surface of the rotating ring, and a fixing ring is welded to the other end of the fixing rod. The reverse thread nut is connected to the fixing ring through the rotating assembly. An internal thread seat is fixedly connected to the surface of the fixing ring, and an external thread rod is sleeved inside the internal thread seat.

[0008] Preferably, the bottom of the positive threaded nut is fixedly connected to a washer ring, the bottom of the washer ring has a groove, an iron ring is welded inside the groove, a magnetic ring is sleeved inside the groove, the top of the magnetic ring is attached to the bottom of the iron ring, and an anti-slip pad is glued to the bottom of the magnetic ring, with the top of the anti-slip pad attached to the bottom of the washer ring.

[0009] Preferably, a fixing seat is fixedly connected to the surface of the fixing ring, a fixing frame is fixedly connected to the other end of the fixing seat, a stop block is welded to the other end of the fixing frame, and the fixing frame is symmetrically distributed.

[0010] Preferably, the surface of the positive thread nut is provided with a protective component, which includes a groove, an anti-wear plate and a screw. The groove is formed on the surface of the positive thread nut, and the anti-wear plate is engaged inside the groove. The anti-wear plate is connected to the positive thread nut by a screw. The protective component is installed on the surface of the negative thread nut.

[0011] Preferably, the external threaded rods are arranged in a ring shape, and a rotating plate is welded to one end of the external threaded rods.

[0012] Preferably, the anti-wear pads are symmetrically distributed, and the screws are symmetrically distributed.

[0013] The nut structure with anti-loosening feature of this utility model has the following advantages:

[0014] 1. This nut structure with an anti-loosening mechanism includes a rotating component inside a forward-threaded nut. This rotating component includes an annular groove, a swivel, and a fixing rod. An annular groove is formed inside the forward-threaded nut, and a swivel is fitted inside the annular groove. A fixing rod is welded to the surface of the swivel, and another fixing ring is welded to the other end of the fixing rod. A reverse-threaded nut is connected to the fixing ring via the rotating component. The annular groove and swivel provide rotatability for both the forward and reverse-threaded nuts. An internal threaded seat is fixedly connected to the surface of the fixing ring, and an external threaded rod is fitted inside the internal threaded seat. When using this nut, the forward and reverse-threaded nuts can be installed in a suitable position by rotating them in opposite directions. The bidirectional thread provides a fixing effect. After the nut is installed in the appropriate position, the external threaded rod can be rotated. Under the action of the internal threaded seat, the external threaded rod can compress the external threaded rod installed on the nut, thereby further improving the stability of the nut after installation and providing an anti-loosening effect.

[0015] 2. This nut structure with an anti-loosening feature involves fixing a washer ring to the bottom of a positive thread nut, creating a groove at the bottom of the washer ring, welding an iron ring inside the groove, and then fitting a magnetic ring inside the groove. The top of the magnetic ring is against the bottom of the iron ring, and an anti-slip pad is adhered to the bottom of the magnetic ring, with its top against the bottom of the washer ring. When using the nut, the magnetic ring can be placed inside the groove until its top is against the bottom of the iron ring, thus securing the anti-slip pad. Afterward, the anti-slip pad can replace the washer ring and directly contact the installation position, preventing wear between the positive thread nut and the installation position, increasing friction, and providing strong protection during use.

[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a nut structure with an anti-loosening mechanism.

[0028] like Figure 1-4As shown, this utility model discloses a nut structure with an anti-loosening mechanism, including a forward-threaded nut 1 and a reverse-threaded nut 2. The forward-threaded nut 1 has a rotating assembly inside, which houses an annular groove 6, a rotating ring 5, and a fixing rod 4. The annular groove 6 is formed inside the forward-threaded nut 1, and the rotating ring 5 is fitted inside the annular groove 6. The fixing rod 4 is welded to the surface of the rotating ring 5, and a fixing ring 3 is welded to the other end of the fixing rod 4. The reverse-threaded nut 2 is connected to the fixing ring 3 through the rotating assembly. By installing the rotating assembly, the annular groove 6 and the rotating ring 5 provide a locking mechanism for the forward-threaded nut 1 and the reverse-threaded nut 2. The rotation effect allows the forward-threaded nut 1 and the reverse-threaded nut 2 to be installed by rotating in opposite directions, which is very convenient to use and provides an anti-loosening effect. The surface of the retaining ring 3 is fixedly connected to the internal thread seat 9, and the internal thread seat 9 is fitted with the external thread rod 10. By installing the internal thread seat 9 and the external thread rod 10, when the nut is installed in the appropriate position, the external thread rod 10 can be rotated. Under the action of the internal thread seat 9, the external thread rod 10 can squeeze the external thread rod 10 installed by the nut, thereby further improving the stability of the nut after installation and providing an anti-loosening effect during use.

[0029] A washer ring 20 is fixedly connected to the bottom of the positive thread nut 1. A groove 13 is formed at the bottom of the washer ring 20. An iron ring 14 is welded inside the groove 13. A magnetic ring 15 is fitted inside the groove 13. The top of the magnetic ring 15 is attached to the bottom of the iron ring 14. An anti-slip pad 16 is glued to the bottom of the magnetic ring 15. The top of the anti-slip pad 16 is attached to the bottom of the washer ring 20. By installing the anti-slip pad 16, when using the nut, the magnetic ring 15 can be placed inside the groove 13 until the top of the magnetic ring 15 is attached to the bottom of the iron ring 14. At this time, the anti-slip pad 16 can be used to directly contact the installation position instead of the washer ring 20. This can ensure that the positive thread nut 1 and the installation position will not wear, while increasing the friction and providing strong protection during use.

[0030] The fixed ring 3 is fixedly connected to the fixed seat 7, and the other end of the fixed seat 7 is fixedly connected to the fixed frame 8. The other end of the fixed frame 8 is welded with a stop block 12. The fixed frames 8 are symmetrically distributed. By installing the stop block 12, the stop block 12 can provide a limiting effect for the external thread rod 10, so that the external thread rod 10 will not detach from the internal thread seat 9, which is very convenient to use.

[0031] The surface of the forward thread nut 1 is provided with a protective component, which includes a groove 17, an anti-wear plate 18, and a screw 19. The groove 17 is opened on the surface of the forward thread nut 1, and the anti-wear plate 18 is engaged inside the groove 17. The anti-wear plate 18 is connected to the forward thread nut 1 by the screw 19. The protective component is installed on the surface of the reverse thread nut 2. By installing the anti-wear plate 18, the anti-wear plate 18 can provide an anti-wear effect for the surfaces of the forward thread nut 1 and the reverse thread nut 2. When the anti-wear plate 18 is worn, it can be replaced by the screw 19. The anti-wear effect is good when in use.

[0032] The external threaded rod 10 is arranged in a ring shape. A rotating plate 11 is welded to one end of the external threaded rod 10. By installing the rotating plate 11, when it is necessary to rotate the external threaded rod 10, the rotating plate 11 can be used directly as the force point, and the external threaded rod 10 can be directly driven to rotate through the rotating plate 11, which is very convenient to use.

[0033] The anti-wear pads 18 are symmetrically distributed, and the screws 19 are also symmetrically distributed. The distribution of the screws 19 can further improve the stability of the anti-wear pads 18 after installation, resulting in strong stability during use.

[0034] The working principle of this anti-loosening nut structure is as follows: When using this nut, first place the magnetic ring 15 inside the groove 13 until the top of the magnetic ring 15 is attached to the bottom of the iron ring 14. This provides a fixing effect for the anti-slip pad 16. A washer 20 is fixedly connected to the bottom of the positive thread nut 1. Since a groove 13 is made at the bottom of the washer 20, and the iron ring 14 is welded inside the groove 13, the magnetic ring 15 is fitted inside the groove 13. The top of the magnetic ring 15 is attached to the bottom of the iron ring 14, and the anti-slip pad 16 is adhered to the bottom of the magnetic ring 15. The top of the anti-slip pad 16 is attached to the bottom of the washer 20. When using this nut, the anti-slip pad 16 can replace the washer 20 and directly contact the installation position. This ensures that the positive thread nut 1 and the installation position will not wear, while increasing friction and providing strong protection during use. The nut can then be used. Since a rotating component is provided inside the positive thread nut 1, this rotating component ensures that the annular groove 6... The ring 5 and the fixing rod 4 are used to form an annular groove 6 inside the positive thread nut 1. A rotating ring 5 is fitted inside the annular groove 6, and a fixing rod 4 is welded to the surface of the rotating ring 5. A fixing ring 3 is welded to the other end of the fixing rod 4. At this time, the negative thread nut 2 is connected to the fixing ring 3 through a rotating assembly. The annular groove 6 and the rotating ring 5 provide a rotatable effect for the positive thread nut 1 and the negative thread nut 2. An internal thread seat 9 is fixedly connected to the surface of the fixing ring 3, and an external thread rod 10 is fitted inside the internal thread seat 9. When using the nut, the positive thread nut 1 and the negative thread nut 2 can be installed in a suitable position by rotating them in opposite directions. The bidirectional thread effect provides a fixing effect for the nut. After the nut is installed in a suitable position, the external thread rod 10 can be rotated. Under the action of the internal thread seat 9, the external thread rod 10 can squeeze the external thread rod 10 installed on the nut, thereby further improving the stability of the nut after installation and providing an anti-loosening effect during use.
