Abstract
The utility model discloses a kind of bolt fastening structure, comprise the groove nose on link, bolt, nut, packing ring, latch, link and structural member, link need the position of construction bolt precast groove nose, its center and installation screw coaxial, size can just by nut, packing ring is put into, nut side is square, one side and groove nose madial wall are pressed close to, structural member and groove nose also have small through hole, latch to insert in the small through hole on link and groove nose and locks, latch blocks another side of nuts and washers, prevent nuts and washers from getting loose, during installation, bolt is screwed into nut by structural member and link installation screw, nut is stoped to rotate in installation process by groove nose madial wall and latch.This bolt fastening structure connects reliable, easy for installation, economical and practical, is restricted at some spatial condition, and technique path is bad cannot be used the place of instrument mounting nuts to play to act on significantly.
Description
Technical field
The utility model belongs to aircraft anchor design field, relates to a kind of aircraft bolt fastening structure.
Background technique
It is one of main Connecting format of aircraft component that bolt connects, due to it simple structure, easy for installation, be easy to dismounting, and there is the features such as join strength height and good reliability, be mainly used in the connection of the main load-carrying construction parts of aircraft, bolt interconnection technique occupies more important status in aircraft manufacturing.Aircraft important load-carrying construction parts are mainly with bolts, and under the restriction of spatial condition, technique path is bad cannot use instrument mounting nuts, plain bolt is connected in aircraft manufacturing and is restricted.
Summary of the invention
In order to solve the problem, the utility model provides a kind of bolt fastening structure, does structural change in nut one end, reaches and does not need instrument fixing just energy construction bolt in nut one end.The technical solution of the utility model is: a kind of bolt fastening structure, comprise groove nose, bolt, nut, packing ring, latch, link and structural member, it is characterized in that: described link needs the position of construction bolt be prefabricated with groove nose and installation screw, described Cao Bi center and installation screw coaxial, size can just by nut, packing ring is put into, described nut side is square, one side and groove nose madial wall are pressed close to, described link and groove nose have small through hole, to lock in small through hole on latch insertion groove nose and link, described latch blocks another side of nuts and washers, prevent nuts and washers from getting loose, during installation, described bolt is screwed into nut by structural member and link installation screw, nut is stoped to rotate in installation process by groove nose madial wall and latch.Described nut is Ball faced nut, and packing ring is spherical washer, described nut and packing ring with the use of, can the laminating degree in adjusting nut end face and connector supporting face automatically, ensure the coaxality of bolt, nut, be convenient to bolt and be screwed into nut.
Accompanying drawing explanation
Fig. 1 is the utility model structural drawing;
Fig. 2 is A-A sectional drawing in Fig. 1.
In figure: 1-groove nose, 2-bolt, 3-nut, 4-packing ring, 5-latch, 6-link, 7-structural member.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.
As accompanying drawing 1, shown in 2, the utility model comprises groove nose 1, bolt 2, nut 3, packing ring 4, latch 5, link 6 and structural member 7, groove nose 1 and installation screw is first precast needing the link installation position connected, groove nose 1 center and installation screw coaxial, the distance at groove nose 1 inner side edge and installation screw center should slightly larger than the distance of nut 3 side to its center, nut 3 and packing ring 4 are put into groove nose 1, nut 3 and packing ring 4 endoporus and link installation screw are alignd, nut 3 one side presses close to groove nose 1 inner side edge, the link and groove nose 1 of another side center position of nut 3 output small through hole, again latch 5 to be inserted in small through hole and to lock, latch 5 blocks another side of nut 3 and packing ring 4, ensure that nut 3 and packing ring 4 can not rotate, during installation, bolt 2 is screwed into nut 3 by structural member 7 and link 6 installation screw, nut 3 is stoped to rotate in installation process by groove nose 1 madial wall and latch 5, such nut 3 side is fixed without the need to instrument, only instrument need be used to install in the first side of bolt 2 to tighten.
