Description
Technical field
The utility model relates to the link between the link that connects between a kind of mechanical components industry, particularly Aeronautics and Astronautics, the steel structure member such as civilian.
Background technique
In airplane design, some influence the tired key position of aircraft safety or the store mounting point that the fuel tank position is provided with, and generally all requiring provides plug-in connection at these tired key positions.If adopt the unallowed tapped hole of structural fatigue design criterion to connect at these regions of high stress that influence fatigue life, will make the potential safety hazard that aircraft exists does not have fixed number.If have the position of fuel tank to design hanging joint outside such connection monolateral, then the problem that fuel tank is difficult to seal can occur.If adopt the outer hanging joint of traditional shoulder shaft type, then can occur assembly precision requirement height, maintainability poor, can't install and remove again, problem such as weight is big.
In civilian industry, bigger in order to solve thickness, the connection between the supporting member, the most frequently used method is that bolt connects.Though such connection is simple in structure, reliable and stable, for being connected of needs dismounting and maintenance, its deficiency is the dismounting trouble, safeguards inconvenience, and inefficiency.
Summary of the invention
For fatigue behaviour, the monolateral fuel tank of solution aircraft that improves housing construction has the sealing problem of store mounting point and alleviates structure weight, the utility model is at prior art above shortcomings part, provide a kind of and can reduce carrying connector element structural design and manufacture difficulty, can alleviate structure weight again, and the reliability height, barrel-shaped self-locking nut link easy to maintenance.
In order to achieve the above object, a kind of barrel-shaped self-locking nut link that the utility model provides, comprise bearing, self-locking nut and retainer, it is characterized in that, described bearing is one and has the half barrel-shaped body unanimous on the whole with hole shape size to be connected, the staving end flat radially extends U-shaped groove of formation, be shaped on bolt in the groove and pass through the hole, be equipped with the self-locking nut of a nut supporting base and described groove bore shape size basically identical on the step surface of described U-shaped groove, at the described staving end flat clamping circular arc crimp elastic opening housing retainer that has a bottom to have to be roughly rectangular opening also.
Bearing end face described in the utility model can be shaped on cylinder pin hole.
The utility model has following beneficial effect than prior art.
The utility model is for the carrying connector element of needs dismounting and maintenance, and the member of especially tired key position connects, and has lightweight construction, reliability height, characteristics easy to maintenance.Not only can improve the fatigability of housing construction, and the problem that can avoid region of high stress Fatigue Design Criterion not allow tapped hole to connect, and connect between the prior art supporting member that maintainability is poor, the problem of mounting or dismounting difficulty again, especially solved the difficult design of store mounting point on all outer hanging joints fatigue key components of airframe and the difficulty that the monolateral fuel tank of aircraft has store mounting point to be difficult to seal.The utility model assembly and bolt constitute than special fastener, have certain motility, convenient to disassembly, efficient.Bearing and circular arc crimp elastic opening housing retainer shape are ingenious, and elastic opening hypertonic degrees of freedom is big, and coupling mechanism force is reliable, and self-lock force is strong.Low to structural requirement, structure is rationally advanced and can save structure space, and installing/dismounting is convenient (single face twisting) very.The operational safety and the maintenance of the outer hanging joint of aircraft can be improved, carrying connector element structural design and manufacture difficulty can be reduced.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Embodiment:
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the barrel-shaped self-locking nut link of the utility model.
In the embodiment shown in fig. 1, this barrel-shaped self-locking nut link comprises bearing shown in Figure 3 14.Described bearing has half a barrel-shaped body unanimous on the whole with hole shape size to be connected, radially is extended with a U-shaped groove 9 as shown in Figure 3 at staving end flat 1, is shaped on the hole 8 that bolt to be connected passes through in the groove.Described hole 8 can be a cone shape hole, also can be cylindrical hole.On the step surface of U-shaped groove 9, be equipped with a self-locking nut 18 as shown in Figure 4.The supporting base 11 of this self-locking nut 18 and described groove 9 bore shapes size basically identical.On the top that is positioned at self-locking nut 18, there is one to have the retainer 16 of flange 2 down, this time flange 2 is clamped in the both sides of described bearing 14 staving end flats 1.Its bottom has the hole that is roughly rectangle, is shaped on the longitudinal elasticity opening along the circular arc crimp 4 of the length direction in its hole.The middle part of the housing retainer of Zu Chenging also is shaped on the hole 3 that bolt to be connected passes through thus.This hole 3, the tapped hole 10 that comprises the self-locking nut 18 under it communicates with hole to be connected 8 shown in Figure 3.In order to limit the one-movement-freedom-degree of self-locking nut 18, be shaped on cylinder pin hole 7 in the two side ends of described bearing 14 respectively in the face of the angle, so that pack elastic cylindrical pin when using into.
Fig. 5 has provided another kind of barrel-shaped self-locking nut link mode of execution, and its main version is the hole 3 that connecting bolt passes through, here neither one through-hole form completely, but protruding cap shaped of two semicolumns of extending vertically.Make it in connection procedure shown in Figure 6, stop further stretching into of connecting bolt.Similar shown in the earlier figures 1～4 of others and present embodiment.
In application examples shown in Figure 6, comprise retainer 16 (can be two kinds of variform retainers) and self-locking nut 18, be placed in the cone shape hole in the bearing 14 according to the foregoing description, after forming the barrel nut link, 2 elastic cylindrical pins are respectively charged in cylinder pin hole 7 small sircle holes of bearing 14 both sides again, retainer 16 are enclosed within the upper end of bearing 14.The barrel-shaped self-locking nut link that assembles is put into the cylindrical hole of mount structure member 15 to be connected.Usually be drilled with two two mutually orthogonal cylindrical holes respectively on the part of two members to be connected, a hole is used for the barrel-shaped self-locking nut link of the utility model, another bolt connecting hole, is fixedlyed connected its mount structure member 15 by connecting the bolt connecting hole on the utility model for connecting bolt 19 with hanger class part 13.
