[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: an alloy steel inner sleeve nut, comprising a nut body 1, the nut body 1 is cylindrical in shape, an internal thread 2 is provided inside the nut body 1 to ensure efficient and stable connection, an anti-slip component is provided on the outer wall of the nut body 1, the anti-slip component is used to improve installation efficiency and avoid errors caused by misalignment of the installation direction, a connecting component is provided inside the nut body 1, the connecting component is used to improve the sealing performance of the nut body 1;

[0032] The anti-slip component includes anti-slip vertical lines 4, which are in a circular array and evenly distributed on the outer wall of the nut body 1, providing sufficient friction during the installation process, so that the operator can grasp the nut more firmly during installation, reducing the risk of sliding and dislocation. An embedded hexagon socket 3 is provided inside the nut body 1, which optimizes the installation space of the nut and enables the operator to operate it conveniently, especially in a small space, and can provide a better operating experience. A bevel chamfer 5 is provided at the bottom of the outer wall of the nut body 1.

[0033] Specifically, when the bolt is screwed into the nut body 1, the internal thread 2 and the external thread of the bolt gradually engage with each other, generating friction and tightening force, ensuring a firm connection between mechanical components. In addition, an embedded hexagonal structure 3 is designed inside the nut body 1, so that it can be easily installed and disassembled in a small or confined space. By cooperating with a universal wrench, the operator can easily tighten or loosen the nut, and can obtain a better operating angle and force even in an environment with limited space without having to clamp the wrench on the outside of the nut for twisting. It also effectively reduces the difficulty of operation caused by angles that traditional tools cannot reach, and the outer wall of the nut body 1 is provided with anti-slip vertical grooves 4, and these vertical grooves are evenly distributed in the form of a circular array. The design of the anti-slip vertical grooves 4 increases the friction between the installation tool or the hand. In installation situations where a larger torque is required, the anti-slip vertical grooves 4 can effectively prevent sliding and slipping, and avoid the tool or nut from slipping when a larger torque is applied, thereby improving work efficiency.

[0034] Reference Figure 1 、 Figure 3 and Figure 4 The connection assembly includes a gasket 6, which is slidably connected to the inside of the nut body 1. The inside of the nut body 1 has two left-right symmetrical through holes 7. The two through holes 7 are provided with internal threads 8 to ensure close fit and rotation locking with the pin 9 and the pin 10. One of the through holes 7 is provided with a pin 9, and the other through hole 7 is provided with a pin 10. The outer walls of the pin 9 and the pin 10 are provided with external threads 11. The two external threads 11 are respectively connected to the two internal threads 8. The outer threads 11 fit tightly with the inner threads 8, so that the pins 1 9 and 10 can be firmly locked in the nut body 1. The pins 1 9 and 10 are both provided with screw holes 12. The pins 1 9 and 10 are both slidably connected inside the gasket 6. The nut body 1 is made of alloy steel with high strength, high hardness and good wear resistance. The high strength and hardness of the alloy steel enable the nut body 1 to withstand large torques and external forces without being easily deformed or damaged.

[0035] Specifically, when the nut body 1 is tightened with the connected component, the gasket 6 will be evenly compressed between the nut body 1 and the connected component to form a sealing effect. The gasket 6 has a certain elasticity, which can adapt to the slight unevenness of the surface during the tightening process to ensure the sealing performance of the fastening part. After the nut body 1 and the gasket 6 are tightened, the stability of the structure needs to be further enhanced by the pin 1 9 and the pin 2 10. The pin 1 9 and the pin 2 10 are respectively designed with external threads 11, which are inserted into the two through holes 7 inside the nut body 1. The inner surface of each through hole 7 is The inner part is provided with an internal thread 28, and the external thread 11 of pin 19 and pin 210 cooperates with the internal thread 28 to ensure that pin 19 and pin 210 are firmly fixed in the nut body 1. After inserting the pin, a special tool can be used to further insert the screw hole 12 inside pin 19 and pin 210, and the pin is completely screwed into the interior of the nut body 1 and the gasket 6 through the screwing tool. The fixing effect of pin 19 and pin 210 not only prevents the displacement of gasket 6 due to factors such as vibration and pressure changes during operation, but also enhances the seismic resistance and pressure resistance of the overall structure.

[0036] Working principle: First, an internal thread 2 is provided inside the nut body 1, which realizes the connection and tightening of mechanical parts by cooperating with external threaded parts such as bolts. When the bolt is screwed into the nut body 1, the internal thread 2 and the external thread of the bolt engage with each other, generating friction and tightening force, and firmly connecting two or more mechanical parts together. The embedded hexagon socket 3 inside the nut body 1 makes it easy to install even in a small space. A universal wrench can be used in conjunction with the embedded hexagon socket 3 to achieve the tightening and disassembly of the nut. At the same time, the outer wall of the nut body 1 is provided with anti-slip vertical grooves 4, which are in a circular array and evenly distributed, increasing the friction between the nut and the installation tool or hand, making it more stable and not easy to slip during the installation and disassembly process. Especially in some installation occasions requiring large torque, the anti-slip vertical grooves 4 can effectively improve the installation efficiency, have the effect of anti-slip and anti-fool, and avoid errors caused by misalignment of the installation direction;

[0037] In addition, when the nut body 1 is tightened, the gasket 6 will be compressed between the nut body 1 and the connected parts, playing a sealing role to prevent leakage of liquid or gas. When the nut body 1 and the gasket 6 are tightened, the pin 1 9 and the pin 2 10 can be inserted into the two through holes 7 inside the nut body 1, and the external thread 11 on the outer wall of the pin 1 9 and the pin 2 10 is engaged with the internal thread 2 8 inside the through hole 7. Then, a tool is used to insert it into the screw hole 12 inside the pin 1 9 and the pin 2 10, and screw it into the nut body 1 and the gasket 6, so that the pin 1 9 and the pin 2 10 can further enhance the sealing effect of the gasket 6, prevent the gasket 6 from being displaced during use, and ensure the stability of the sealing performance.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. 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.
