Detailed Description
As shown in fig. 1 to 6, a sealed locking type fastening nut, it adopts brand-new structural design, through the locking stable connection groove that is equipped with circumference evenly distributed at the lower extreme position of nut major structure to through set up locking reinforcement groove in the inside of locking stable connection groove, can play the locking cooperation fastening of dual seal, it is more reliable to have ensured the whole fastness when the installation cooperation, and the security when later stage uses is higher. The nut comprises a mounting and matching fastening nut body 1 with a regular hexagon projection on a horizontal plane, wherein a cylindrical body assembling and locking fixed connecting hole 2 penetrating through the lower end face of a part is formed in the center of the upper end of the mounting and matching fastening nut body 1, and the mounting and matching fastening nut body is a main body connecting structure used in nut fastening. The upper end and the lower end of the main body assembling, locking and fixing connecting hole 2 are respectively provided with a symmetrical conical assembling, assembling and assembling guide groove 3, so that the operation is easier during assembling at the central position, and the fastening and guiding cooperation effect is realized. The lower extreme of installation cooperation fastening nut main part 1 is equipped with six sealed safe combination locking stable connection grooves 4 of U-shaped that open side down, can carry out the fastening fit with the sealing washer when fastening together, can make the sealing washer impress this position after the fastening, and guarantee sealing safety is more reliable. The left and right side end faces of the sealed safe combined anti-loosening stable connecting groove 4 are respectively provided with an arc-shaped tight-fit stable anti-loosening reinforcing groove 5 which is distributed up and down, so that the double-sealing anti-loosening fastening effect is achieved, and the use requirements in application environments with higher sealing requirements can be met.
