Structural columns upper end inward direction is provided with the interior protuberance for being mounted on retention device in antiratchetting groove, in groove structure cylinder
Upper end outward direction is provided with the male part for taking out retention device, and groove structure cylinder bottom is provided with integrally formed bottom
Seat, pedestal both ends each extend over out groove structure cylinder.
In the present invention, groove structure column body bottom end is arc, in favor of taking out retention device.
In the present invention, eight card slots are evenly equipped on groove structure cylinder.
In the present invention, the interior protuberance of groove structure cylinder upper end inward direction setting is semicircle.
In the present invention, antiratchetting groove is semi arch structure, the interior protuberance with the setting of groove structure cylinder upper end inward direction
Matching, for retention device to be pressed into antiratchetting groove.
In the present invention, when installation, bolt is inserted into the bolt connecting hole being arranged on component A and component B first, tight
Component B successively installation and adjustment gasket, nut, adjusting gasket are pasted, and tightens nut, finally by retention device along the screw thread side of bolt
It into indentation antiratchetting groove, loosen retention device can not voluntarily from bolt, to limit nut movement, reach anti-loosing effect.
The utility model has the advantages that the configuration of the present invention is simple, install convenient, locking precision is high, in the lesser region in aircaft configuration space,
It using this connection, does not easily cause screw bolt and nut to destroy, effectively mitigates the operating difficulty of worker, can also realize bolt, nut
It reuses.
