Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described.
Fig. 1 is the structural representation of assembled nut described in the utility model; Fig. 2 is the structural representation of collar pivot pin described in the utility model, as shown in Figure 1 and Figure 2, a kind of assembled nut, comprise sleeve 1, described sleeve 1 is barrel-like structure, and the bottom of described sleeve 1 inside is provided with bolt hole 3, is provided with multiple collar 4 in described sleeve 1, the top of described sleeve 1 is provided with collar pivot pin 5, and the upper end of described collar pivot pin 5 is provided with dust cover 6.
Described collar pivot pin 5 comprises hexagon nut 51, jack-post 52, and described hexagon nut 51 is hexagonal socket nut, and the outside of described hexagon nut 51 is circular, and the diameter of described hexagon nut 51 outer circular equals the internal diameter of described sleeve 1.
The inner side of described sleeve 1 is provided with screw thread, and the inside and outside both sides of the described collar 4 are equipped with screw thread, the screw thread inside described sleeve 1 and the threaded engagement outside the described collar 4.
The bottom of described sleeve 1 is provided with dustproof gasket 7, and described dustproof gasket 7 is round structure, and the diameter of described dustproof gasket 7 equals the external diameter of described sleeve 1.
Between described dust cover 6 and collar pivot pin 5, the bottom of described sleeve 1 is equipped with welding gasket 2, welding gasket 2 between described dust cover 6 and collar pivot pin 5 is placed in described sleeve 1, and welding gasket 2 and the described sleeve 1 of the bottom of described sleeve 1 are the overall structure of single injection-molded.
Described hexagon nut 51 is the overall structure of single injection-molded with described jack-post 52.
The quantity of described jack-post 52 is multiple, and described multiple jack-post 52 with the center of described hexagon nut 51 for center of circle array distribution in the form of a ring.
The described collar 4 is provided with axis hole, and described jack-post 52 runs through the described collar 4 by axis hole.
The outer upper of described dust cover 6 is provided with hexagonal spiral shell side, and the outer lower portion of described dust cover 6 is provided with screw thread, the screw thread outside described dust cover 6 and the threaded engagement inside described sleeve 1.
Installation steps:
(1) dustproof gasket 7 is enclosed within bolt;
(2) collar 4 is enclosed within collar pivot pin 5;
(3) by hexagon nut 51, the collar 4 is screwed in sleeve 1;
(4) by hexagon nut 51, the collar 4 is screwed on bolt;
(5) welding gasket 2 is put into;
