Drawings
FIG. 1 is a schematic view of the external structure of the present invention;
FIG. 2 is a schematic view of the internal structure of the present invention;
fig. 3 is a schematic view of the external structure of the utility model when the locking sleeve is taken out.
In the figure: nut body 1, sliding part 2, stay 3, opening 4, lock sleeve 5, fender portion 6.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 to 3, the high-strength wind power fastening nut comprises a nut body 1, wherein the lower end of the nut body 1 is fixedly connected with a sliding part 2, the lower end of the sliding part 2 is fixedly connected with a locking part, and the nut is provided with an internal thread hole which penetrates through the nut body 1, the sliding part 2 and the locking part.
Locking portion comprises two semicircular pipe shape stay 3, has opening 4 between the adjacent stay 3, and the outside of locking portion 3 has the external screw thread, and locking portion originally is holistic tubulose, cuts out opening 4 after and just forms the stay, consequently runs through on the external screw thread of higher authority, sliding connection lock sleeve 5 on the sliding part 2, and lock sleeve 5 has the internal thread that corresponds with the external screw thread of locking portion.
In the present invention, the diameter of the nut body 1 is larger than the diameter of the sliding portion 2, so that the distance of the locking sleeve 5 sliding upward can be restricted.
The utility model discloses in, the outside lower extreme of stay 3 sets up fender portion 6, and fender portion 6 is semicircle ring block structure, can restrict the gliding distance down of lock sleeve 5 like this.
During the use, will earlier the utility model discloses on twisting the part that corresponds, 1 one end of nut body is inwards, then with 5 rotations outwards of lock sleeve, makes 5 spiro couplings of lock sleeve in locking portion, and two stay 3 of locking portion receive 5 extrudees of lock sleeve and shrink inwards, and then make the utility model discloses firmly lock on the part that corresponds, be difficult to the pine and take off.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
