Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc. Fasteners are used to achieve fastening and connection effects.

[0003] The high-strength fastener structures currently available on the market have the following problems in actual use:

[0004] 1. In the actual use of traditional high-strength fastener structures, since the nut is a whole, when a large force is applied during use, the threads inside the nut may be stripped. At this time, the traditional nut does not have a device for replacing the internal threads, and the entire nut can only be replaced, which increases the cost when used;

[0005] 2. During the use of most high-strength fastener structures, since high-strength fasteners are used to fasten parts, it is necessary to install gaskets to protect the surface of the connecting parts from being scratched. However, the surface of traditional gaskets is relatively smooth and the friction coefficient is small. At this time, when installing high-strength fasteners, it may cause unstable installation and poor stability during use. Utility Model Content

[0029] In order to better understand the purpose, structure and function of the utility model, the high-strength fastener structure of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1-6 As shown, a high-strength fastener structure of the utility model includes a nut 4, a first slot 7 is provided inside the nut 4, an internal threaded ring 8 is installed inside the first slot 7, by installing the internal threaded ring 8, when the thread inside the internal threaded ring 8 is stripped, the internal threaded ring 8 can be taken out and replaced, and there is no need to replace the nut 4 as a whole, thereby reducing cost consumption, a clamping block 9 is fixedly connected to the surface of the internal threaded ring 8, and the clamping block 9 is embedded in the first slot 7, a slot 11 is provided on the surface of the nut 4, a limiting slot 12 is provided on the surface of the clamping block 9, an insert block 10 is installed in the slot 11, and one end of the insert block 10 is embedded in the limiting slot 12, by installing the clamping block 9, when the nut 4 is used, the first slot 7 can be used to limit the clamping block 9, so that the internal threaded ring 8 drives the nut 4 to rotate when rotating, which is very convenient to use.

[0031] A gasket 3 is provided on the outside of the nut 4, and an annular groove 16 is provided at one end of the gasket 3. The gasket 3 is made of metal iron. A magnet ring 19 is clamped inside the annular groove 16, and a rubber ring 18 is bonded to one end of the magnet ring 19. A rubber strip 20 is fixedly connected to the inside of the rubber ring 18. A second clamping groove 17 is provided at one end of the gasket 3, and the rubber strip 20 is embedded in the second clamping groove 17. By installing the rubber strip 20 and the rubber ring 18, when high-strength fasteners are used to fasten the parts, the rubber ring 18 and the rubber strip 20 will contact the surface of the connecting part, which not only ensures that the surface of the connecting part will not be scratched, but also increases the friction between the surface of the connecting part and the gasket 3, and has strong stability during use.

[0032] An externally threaded rod 2 is installed inside the internally threaded ring 8, one end of the externally threaded rod 2 is fixedly connected to the nut 1, and one end of the nut 1 is fixedly connected to the anti-slip strip 22. By installing the anti-slip strip 22, when high-strength fasteners are used to fasten parts, the friction of the nut 1 can be increased through the anti-slip strip 22, so that the nut 1 will not slide during installation and has greater stability during use.

[0033] A reinforcing cap 5 is welded to the other end of the nut 1, and a screw 6 is installed inside the reinforcing cap 5. One end of the screw 6 is embedded in the external threaded rod 2. By installing the screw 6, the internal part of the external threaded rod 2 is reinforced to improve the strength of the external threaded rod 2, and the strength is higher when in use.

[0034] The rubber strip 20 is distributed in a ring form, and the handle 21 is bonded to the surface of the rubber ring 18. The handle 21 is distributed in a symmetrical form. By installing the handle 21, when the rubber ring 18 and the rubber strip 20 need to be replaced, the rubber ring 18 can be directly pulled upward using the handle 21 until the magnet ring 19 is separated from the annular groove 16. After that, it can be replaced, which is very convenient to use.

[0035] A positioning groove 13 is provided on the surface of the nut 4, and the other end of the plug block 10 is fixedly connected to a magnet plate 14, which is embedded in the positioning groove 13. A groove 15 is provided on the surface of the magnet plate 14. The nut 4 is made of metal iron. By installing the magnet plate 14, on the premise that the nut 4 is made of metal iron, the magnet plate 14 can be fixed in the positioning groove 13 by using the magnetic attraction effect, thereby providing a fixing effect for the plug plate, which is very convenient to use.

[0036] The working principle of the high-strength fastener structure: when using the high-strength fastener structure, the external thread ring should be installed inside the nut 4 first, and the block 9 should be embedded in the first slot 7. Then the plug-in board should be inserted into the slot 11 until one end of the plug-in board is embedded in the limit slot 12. At this time, the magnet plate 14 will be embedded in the positioning slot 13, and the magnet plate 14 will be fixed in the positioning slot 13 by the magnetic attraction effect, thereby providing a fixing effect for the plug-in board, which is very convenient to use. Then, the magnet ring 19 is embedded in the annular groove 16, and the rubber strip 20 is embedded in the second slot 17. Under the premise that the material of the gasket ring 3 is metal iron, the magnetic attraction effect is also used to fix the magnet ring 19 in the annular groove 16, and then the rubber ring 18 and the rubber strip 20 are fixed on the gasket ring 3. After that, high-strength fasteners can be used to fasten the parts. When in use, first pass the external threaded rod 2 through the parts to be connected, then put the gasket 3 in, and finally rotate the nut 4 to install it on the external threaded rod 2. During the rotation process, the rubber ring 18 and the rubber strip 20 will contact the surface of the connecting part, which not only ensures that the surface of the connecting part will not be scratched, but also increases the friction between the surface of the connecting part and the gasket 3. It has strong stability when in use. When the force is too large and the threads inside the internal threaded ring 8 are stripped, first take out the plug 10 through the groove 15 to release the fixing effect of the internal threaded ring 8. Then take out the internal threaded ring 8 for replacement. There is no need to replace the nut 4 as a whole, which reduces the cost. Finally, the parts can be fastened and connected.
