Abstract
The utility model discloses a kind of fuel jettison stud, including the first connection end (1) and second connection end (2), outer hexagonal structure (6) is externally provided with the first connection end (1), counter bore structure is provided with the inside of the first connection end (1), internal thread (4) is provided with counterbore；Second connection end (2) is provided with external screw thread (3).Fuel jettison stud of the present utility model at any time can dismantle body, realize critical activity demand, and the stud of this kind of structure is widelyd popularize in Aeronautics and Astronautics field.
Description
Technical field
The utility model belongs to stud internal and external threads connection technique field, more particularly to a kind of fuel jettison spiral shell
Stake.
Background technology
In the prior art at present, stud connection is most widely used.But being fixedly connected between realizing two bodies, again
Realize that one of body is intact and flexibly remove stubborn disassembling function, effectively retreat during work, can be pinned after screwing, therefore
It is badly in need of a kind of stud that can realize such function in the prior art.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of fuel jettison stud, so as to realize two
Being fixedly connected between individual body while realize that one of body is intact and flexibly remove stubborn disassembling function.
What the utility model was realized in：
The utility model is a kind of fuel jettison stud, and stud structure of the present utility model is mainly by four part groups
Into：Internal thread position, external screw thread position, outer six sides position, insurance hole portion position.Specifically, connect including the first connection end and second
End is connect, outer hexagonal structure is externally provided with the first connection end, counter bore structure is provided with the inside of the first connection end, is provided with counterbore interior
Screw thread；Second connection end is provided with external screw thread.
Further, insurance hole is provided with outer hexagonal structure, is positioned for being pinned by fuse.
Further, connected between the first connection end and second connection end by embedded neck.
The utility model can solve the problem that the close-coupled between two bodies, is removed at any time by outer-hexagonal face and twists screw-in, screws out
Body, after assembling, stud can lock quickly, and fuse prevents from；When needing fuel dump, fuse can be taken
Go out, emergent dismounting is played a part of by the stubborn can of flexibly removing of external six side.
Fuel jettison stud of the present utility model at any time can dismantle body, realize critical activity demand, this kind knot
The stud of structure is widelyd popularize in Aeronautics and Astronautics field.
Brief description of the drawings
Fig. 1 is axial sectional view of the present utility model；
Fig. 2 is radial cross-section of the present utility model.
Description of reference numerals：The connection ends of 1- first, the connection ends of 2- first, 3- external screw threads, 4- internal threads, 5- insurances hole, 6-
Outer hexagonal structure, 7- necks.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, stud of the present utility model includes the first connection end 1 and second connection end 2, the He of the first connection end 1
Connected between second connection end 2 by embedded neck 7.Outer hexagonal structure 6 is externally provided with the first connection end 1, in the first connection
The inside at end 1 is provided with counter bore structure, and internal thread 4 is provided with counterbore；Second connection end 2 is provided with external screw thread 3.In outer hexagonal structure 6
Insurance hole 5 is provided with, insurance hole 5 passes through two faces of adjacent outer hexagonal structure 6, as shown in Figure 2.
Carry out removing stubborn effect by the external hexagonal structure 6 of external force during implementation, by 3 two positions of internal thread 4 and external screw thread point
Do not screw on two bodies, two bodies is firmly coupled；When external screw thread 3 is screwed into operating position, to prevent from, profit
Positioning is pinned from the position in insurance hole 5 with external failsafe silk, reaches preferable working condition；When fuel dump works, flexibly
Ground takes out fuse from insurance hole 5, and the external application of hexagonal structure 6 effect remove stubborn, at any time can dismantle body, realize
Critical activity demand.
Certainly, it is above concrete application example of the present utility model, the utility model also has other embodiments, all
The technical scheme formed using equivalent substitution or equivalent transformation, all fall within the protection domain required by the utility model.
