Detailed Description

As shown in fig. 1 to 7, a sealed safe hexagonal nut, it adopts brand-new structural design, through being equipped with sealing connection stabilization post in hexagonal nut's lower extreme position, it is better to ensure the combination leakproofness of inside and outside position when assembling, thereby can satisfy high leakproofness mechanical component's installation demand, the security of guarantee when using is higher, its inboard sealed position is through setting up sealed locking cooperation groove, can make inboard sealing stability more reliable, whole durability in the later stage use is stronger. The nut fastening structure comprises a nut fastening main body structure 1, wherein an integrally formed cylindrical sealing connection stabilizing column 2 is arranged at the center of the lower end of the nut fastening main body structure 1, and the nut fastening main body structure is a main structure which plays a role of a sealing component during assembly. The lower end outer edge position of the sealing connection stabilization column 2 is provided with an assembly guide matched connection arc 3, the outer side position is better in smoothness when being assembled, and a sealing ring is matched with the outer side position to combine, so that the sealing effect of the outer side is guaranteed. The upper end center position of nut fastening major structure 1 is equipped with the cylindrical center built-up connection hole 4 that runs through part lower extreme face, the upper end position of center built-up connection hole 4 is equipped with main part fastening connection screw thread 5, carries out the screw thread built-up connection of main part through it. The lower end of the central combined connecting hole 4 is provided with a cylindrical sealing combined fastening groove 6, and the cylindrical sealing combined fastening groove can be matched with a sealing ring to carry out inner combined sealing connection when being assembled. The lower end face of the sealing connection stabilizing column 2 is provided with a cylindrical sealing anti-loosening stable connection combining groove 7 which is communicated with the sealing combination fastening groove 6 and is uniformly distributed on the circumference, the sealing stability of the sealing ring is guaranteed after fastening, and the higher overall sealing safety of the inner side is guaranteed.
