[0020] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, based on the embodiments of the present application, all other embodiments obtained by the ordinary skilled in the art without creative labor are within the protection scope of the present application.

[0021] Please refer to Figures 1-4 The utility model provides the following technical scheme: a split type high strength corrosion -resistant hub nut, including theftproof nut 1, theftproof nut 1's left side fixed mounting has main nut 2, and the inside of theftproof nut 1 and main nut 2 all are seted up internal thread 6, and the inside of main nut 2 is through, and the inside of theftproof nut 1 is not through, and theftproof nut 1's right side fixed mounting has mounting disc 9, and the diameter of mounting disc 9 is less than the diameter of theftproof nut 1, and the surface of mounting disc 9 is fixedly installed with fixed block 10, and fixed block 10 is provided with a plurality of, and a plurality of fixed blocks 10 are arranged in the surface of mounting disc 9 in circle, and the surface of theftproof nut 1 and main nut 2 is provided with corrosion -resistant coating, and the cross section of main nut 2 is hexagonal, and the cross section of theftproof nut 1 is circular.

[0022] The left side of the main nut 2 is fixedly installed with a connecting disc 3, and the diameter of the connecting disc 3 is greater than the diameter of the theftproof nut 1.

[0023] The right side of the theftproof nut 1 is provided with a protective cover 4, and the upper and lower sides of the inner wall of the protective cover 4 are fixedly installed with clamping blocks 13.

[0024] The surface of the protective cover 4 is rotatably installed with a movable ring 5, and the front and rear sides of the surface of the movable ring 5 are provided with mounting holes 12. The front and rear sides of the surface of the protective cover 4 are provided with fixing holes 11, and the size of the fixing holes 11 is the same as the size of the mounting holes 12.

[0025] The combination of the theft-proof nut 1 and the main nut 2 enables the device to better fix the hub on the axle frame, the split design of the hub nut can ensure the stable connection between the wheel and the hub, prevent it from falling off or loosening during driving, thereby reducing the risk of accidents and improving the safety of vehicle driving. The combination of the mounting disc 9 and the fixing block 10 enables the theft-proof nut 1 to be disassembled only by a specially designed wrench, effectively preventing illegal disassembly. Since the theft-proof nut 1 and the main nut 2 are both made of high-carbon steel and are both heat-treated, the hardness of the theft-proof nut 1 and the main nut 2 can be effectively improved, which is beneficial to making the hub nut have higher strength. The corrosion-resistant coating on the surface of the theft-proof nut 1 and the main nut 2 can improve the corrosion resistance of the hub nut, making the hub nut more durable. The interlocking of the clamping block 13 and the clamping groove 8 can facilitate the fixation of the protective cover 4 on the surface of the theft-proof nut 1 and the main nut 2. By wrapping the theft-proof nut 1 and the main nut 2, the theft-proof nut 1 and the main nut 2 can be protected. The protective cover 4 can prevent moisture or other corrosive substances from entering the nut interior, thereby playing a role in rust and corrosion prevention. This can protect the nut and the connecting piece from erosion and prolong their service life. Since the clamping block 13 and the clamping groove 8 are provided with two groups, the firmness of the installation of the protective cover 4 can be ensured. The setting of the connecting disc 3, and since the diameter of the connecting disc 3 is larger than that of the theft-proof nut 1, the connecting disc 3 can increase the contact area. By increasing the contact area, the connection force and stability can be significantly improved. This design enables the nut to withstand greater pressure and vibration. Since the six rubber pieces 7 are arranged in a circular manner on the left side of the connecting disc 3, the friction between the connecting disc 3 and the contact surface can be increased, preventing the nut from loosening and ensuring the stable and safe operation of the equipment. By rotating the movable ring 5 and making the mounting hole 12 and the fixing hole 11 in the same position, the tool can be inserted into the interior of the fixing hole 11 and the mounting hole 12, thereby facilitating the prying of the protective cover 4. After the protective cover 4 is installed, the movable ring 5 can be rotated to make the positions of the mounting hole 12 and the fixing hole 11 staggered, which can facilitate the closure of the protective cover 4 and prevent water from entering the interior of the protective cover 4, thereby improving the protective effect of the protective cover 4.

[0026] In one aspect of the present embodiment, the connecting disc 3 is provided, and since the diameter of the connecting disc 3 is larger than that of the theft-proof nut 1, the connecting disc 3 can increase the contact area. By increasing the contact area, the connection force and stability can be significantly improved. This design enables the nut to withstand greater pressure and vibration. Since the six rubber pieces 7 are arranged in a circular manner on the left side of the connecting disc 3, the friction between the connecting disc 3 and the contact surface can be increased, preventing the nut from loosening and ensuring the stable and safe operation of the equipment.

[0027] In one aspect of the embodiment, the protective cover 4 can be fixed on the surface of the anti-theft nut 1 and the main nut 2 by the clamping of the clamping block 13 and the clamping groove 8, and the anti-theft nut 1 and the main nut 2 can be protected by being wrapped, and the protective cover 4 can prevent moisture or other corrosive substances from entering the nut, thereby playing a role in rust and corrosion prevention. This can protect the nut and the connecting piece from corrosion and prolong their service life, and since the clamping block 13 and the clamping groove 8 are provided with two groups, the firmness of the installation of the protective cover 4 can be ensured.

[0028] In one aspect of the embodiment, the tool can be inserted into the inside of the fixing hole 11 and the mounting hole 12 by rotating the movable ring 5 and making the mounting hole 12 and the fixing hole 11 in the same position, so as to facilitate the prying of the protective cover 4, and after the installation of the protective cover 4, the movable ring 5 can be rotated to make the positions of the mounting hole 12 and the fixing hole 11 staggered with each other, so as to facilitate the sealing of the protective cover 4 and prevent water from entering the inside of the protective cover 4, which is conducive to improving the protection effect of the protective cover 4.

[0029] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for some technical features.
