Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
Fig. 1 is referred to, the utility model includes nut body 1, seal closure 2 and pedestal 3.
Fig. 2 is referred to, the inner wall of the nut body 1 is equipped with internal thread, and 1 one end margin of nut body is circumferentially uniform
Multiple positioning card valves 11 are provided with, the end face at the end is formed with hollow concave ball shape curved surface 12, and the other end uniformly closes up and forms circular cone
Face 13 equidistantly offers multiple bar-shaped troughs 14 on the circular conical surface 13 in an axial direction.The nut body 1 and circular conical surface 13 it is interior
Wall is equipped with continuous internal thread.In the present embodiment, the quantity of the bar-shaped trough 14 is 6, and circular conical surface 13 is by even partition
Six cone angle faces, and six cone angle faces become elastic element.
Fig. 3 is referred to, the seal closure 2 is the columnar structured of one end open, is circumferentially uniformly provided on barrel more
A and 11 matched location hole 21 of positioning card valve, the seal closure 2 can be sheathed on the nut body 1, and by that will determine
Position card valve 11, which is caught in location hole 21, to be pre-fixed.
Fig. 4 is referred to, the pedestal 3 includes hollow circular base plate 31, and one end of circular base plate 31 is equipped with and concave ball shape
The matched hollow convex sphere curved surface 32 of curved surface 12, the circular base plate 31 can be by squeezing opening for the embedded seal closure 2
Mouth end, realizes the tight fit between pedestal 3 and seal closure 2.
In the present embodiment, the open end of the seal closure 2 is equipped with flange 22, and flange 22 is equipped with mounting hole 23, convenient for peace
Dress uses.
