Abstract
The utility model relates to a connection structure of sealed screw joint. Grooves are arranged on a joint between bottoms of screw hole sockets of upper and lower installation pieces and bolts. Sealing pieces are arranged in the grooves. The bolts sequentially penetrate through the seal pieces which are arranged in the grooves and the screw holes of the upper and lower installation pieces and are fixedly connected through screw nuts. A sealing piece is arranged between the upper and lower installation pieces. The bolts sequentially penetrate through the sealing pieces which are arranged in the grooves of the upper and lower installation pieces, screw holes of the upper and lower installation pieces and the sealing piece between the upper and lower installation pieces, and are fixedly connected through screw nuts of a support board. The seal pieces are seal rings or rubber boards. Head portions of the bolts are used to flatten the ring-shaped gaskets to prevent oil leakage of the bolts. The sealed bolt joint reduces weight obviously and is convenient to install and good in sealing effect.
Description
Technical field
The utility model relates to the mechanical connection structure, particularly the linkage structure that is spirally connected of a kind of sealing.
Background technique
Aircraft has adopted a large amount of bolt connection pieces in passenger cabin, integral tank section, and the airtight, oily close of bolt installation is to solve.The sealing form of being spirally connected of passenger cabin, the employing of integral tank section is to adopt 3 sealings of steel bowl packing ring at present, such as Fig. 1, or at bolt tail employing sealing nut 6, such as Fig. 2, the assembly weight that this seal form is brought is heavy, back gauge requires greatly, and affects other paths that become annexes to install on the structure.
Summary of the invention
The purpose of this utility model is: propose the method that a kind of sealing bolt connects, rear loss of weight is obvious so that sealing bolt is linked and packed, and drilling is simple, convenient, and sealing effect is good.
The technical solution of the utility model is: the linkage structure that a kind of sealing is spirally connected, the bottom of assembling set screw nest and bolt joint are provided with groove up and down, Sealing is housed in the groove, and the screw of the Sealing that is equipped with in the screw bolt passes groove and assembling set up and down also is fixedly connected with by nut.
Between described up and down assembling set Sealing is housed, the Sealing that screw bolt passes is equipped with in the groove of assembling set up and down, up and down screw and the Sealing between assembling set and be fixedly connected with by plate nut up and down of assembling set.
Described Sealing is seal ring or rubber plate.
Advantage of the present invention is: flatten ring washer to prevent the bolt leakage of oil by bolt head, it is obvious that this sealing bolt connects loss of weight weight, and easy for installation, and sealing effect is good.
