Detailed Description
The structure of the auxiliary nut of the present invention will be further described below with reference to specific embodiments to help those skilled in the art to understand the concept and technical solution of the present invention more completely, accurately and deeply.
Example 1
As shown in fig. 7 to 9, the auxiliary nut mounting structure of the present embodiment includes a first member 10, a second member 20, an anti-rotation bracket 30, a hexagonal flange nut 40, and a bolt 50. The second component 20 comprises a bottom plate 21 and a shell 22 arranged on the bottom plate 21, wherein the upper end of the shell 22 is an installation surface 24, the bottom plate 21 is provided with bolt holes 23, the installation surface 24 is provided with installation holes 25, and the installation surface 24 is further provided with positioning holes 26. The first member 10 includes a sleeve 11 and a shaft hole 12 provided in the sleeve 11. Prevent changeing support 30 includes support body 32 and face of weld 31, be provided with counterpoint hole 36 on the face of weld 31, be provided with regular hexagon hole 33 on the support body 32. The hex flange nut 40 is placed on the mounting surface 24 and aligns the hex flange nut 40 with the mounting hole 25. Aligning the alignment holes 36 with the alignment holes 26 aligns the regular hexagons 33 of the bracket body 32 with the nuts 40 and allows the nuts 40 to fit over the bracket body 32 with the distance L between the bracket body 32 and the mounting surface 241Is less than the height L of the hexagonal flange nut 402.
