Description

A kind of anti-loosening device of bolt
Technical field
The present invention relates to aircaft configuration technical field more particularly to a kind of anti-loosening device of bolt.
Background technique
Aeroplane structure design uses a large amount of bolt fastening structures, but this kind of structure is both needed to carry out locking processing, and bolt is anti- Loose measure formula mainly has the modes such as split pin, stop washer, fuse, punching point;But it in the region that structure is complicated, space is small, uses There are various defects in above-mentioned locking mode: operating difficulties and being difficult to reach standard requirements, the locking mode in part also easily causes spiral shell Screw bolt and nut destroys, and then causes bolt that cannot reuse.
Summary of the invention
Technical problem solved by the invention is to provide a kind of anti-loosening device of bolt, to solve in above-mentioned background technique Disadvantage.
Technical problem solved by the invention is realized using following technical scheme:
A kind of anti-loosening device of bolt, including bolt and the retention device being mounted on bolt, wherein bolt is to lengthen knot Structure, and the antiratchetting groove for installing retention device is machined in the elongated portion of bolt;Retention device is made of elastic material Groove structure cylinder is evenly equipped with multiple card slots on groove structure cylinder, for elastic with bolt installation strength, while in groove 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.
