Abstract
A kind of fall-preventing device slotted nut, six U-groove bevels are processed at slotted nut end face, diameter slightly larger than the tapped hole diameter of fixed block, angle at about 6 °, on the basis ensureing slotted nut rigidity, widen the overlapping area of U-groove bevel and fixed block tapped hole, when resetting to butterfly spring, as long as rotary slotted nut, the tapped hole of fixed block is made to be in the middle of slotted nut U-groove bevel, the installation can carrying out bolt is fixed, thus reaches the object of the work of being simplified to fix.
Description
Technical field
The utility model relates to a kind of slotted nut, and especially a kind of butterfly spring is convenient to the fall-preventing device slotted nut fixed after resetting.
Background technique
At present, known fall-preventing device slotted nut is uniform 6 circular holes on end face, in order to after fall-preventing device butterfly spring resets, are connected to be fixed by bolt through circular hole with the tapped hole on fixed block.But necessarily require the circular hole on slotted nut and the tapped hole on fixed block to align completely when construction bolt, bolt could be installed smoothly, it is accurately fixed that hand reset and range estimation are but difficult to ensure to align, and makes steady job become complicated especially.
Summary of the invention
In order to overcome the circular hole on slotted nut and the tapped hole on fixed block is difficult to align the deficiency causing steady job complexity, the utility model provides a kind of fall-preventing device slotted nut, this slotted nut can facilitate the circular hole on slotted nut and the tapped hole on fixed block to align, thus is simplified to fix work.
The utility model solves the technological scheme that its technical problem adopts: process six U-groove bevels at slotted nut end face, diameter is slightly larger than the tapped hole diameter of fixed block, angle is at about 6 °, on the basis ensureing slotted nut rigidity, widen the overlapping area of U-groove bevel and fixed block tapped hole, when resetting to butterfly spring, as long as rotary slotted nut, the tapped hole of fixed block is made to be in the middle of slotted nut U-groove bevel, the installation can carrying out bolt is fixed, thus reaches the object of the work of being simplified to fix.
The beneficial effects of the utility model are, can increase the overlapping area of U-groove bevel and fixed block tapped hole, be simplified to fix work, structure is simple.
