Description
Technical field
The utility model is related to a kind of attachment devices that civil aircraft hydraulic pressure product part is connect with fuselage, belong to mechanical processing manufacture
Field.
Background technology
Currently, hydraulic pressure ready system products part fuel tank, electrodynamic pump and PTU are required for overflow liquid machine is discharged on civil aircraft
Outside, fuel tank fuel outlet is also required to outside fluid discharge machine by pipeline, and the quality of these pipelines assembly is to influence aircraft certain
Fault condition make decision aircraft can the vital ring of safe landing, traditional method is that overflow, EP rubbers of draining the oil is soft
Pipe sleeve increases contact area in finished parts overflow, the tip side of fuel outlet, using the elasticity and lengthening of EPR hoses makes it be fitted in
On connector, EPR materials not only abrasion deformation easy to aging is visual poor, and when oil pressure is bigger, and hose is de- easily from connector
It falls, such connection type is unstable.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of connection that civil aircraft hydraulic pressure product part is connect with fuselage dresses
It sets, oil inlet pipe is fixedly connected with finished parts by turbine and worm clip by flange bracket, is not easy to fall off with finished parts, is improved
Security performance.
In order to solve the above problem, the specific technical solution of the utility model is as follows：A kind of civil aircraft hydraulic pressure product part and fuselage
The attachment device of connection, it is characterised in that：Pipeline one end of draining the oil is connected with flange bracket, and the other end is connected with connector, drain line
There are two turbine and worm clips for road excircle suit；The flange bracket structure is：Flange head excircle is set with detachably
Divided ring and ring flange, ring flange are located above divided ring, and ring flange is equipped with bolt, the upper and lower side of bolt-through ring flange
Face, bolt are equipped with nut, and nut is located at below ring flange.
The bolt is more than two, is evenly distributed on ring flange.
The flange bracket combination of two uses, two ring flanges of bolt-through, two groups of divided rings and flange head position
It corresponds.
What the utility model was brought has the beneficial effect that：It is equipped with turbine and worm clip in overflow, fuel outlet connector and fixes, prevent
Pipeline equal installation forms instability problem easy to fall off；Completely new flange combination holder, by flange head, divided ring, ring flange, bolt
It is combined with nut, has many advantages, such as that flexibility is good, be easily installed, be easily changed, is cost-effective；Nearby pipeline end uses method to fuselage
Blue sectional shelf-unit is equipped with turbine and worm clip and fixes, and has not only saved human cost and the working hour in airplane design stage, but also solves
The problem of control overflow, relative position between pipeline and theoretical shape of draining the oil of having determined, improve the optimization of aircraft aerodynamic performance.
The assembly method that hydraulic pressure product part is connect with fuselage have light-weight, high and low temperature resistance and corrosion resistance, resistance to atmospheric aging,
Visual good, high lubrication, good insulating, nonhazardous, non-stick, connection type are stablized, and anti-dropout is conducive to aircraft aerodynamic performance
The advantages that.Therefore, the present invention is aircraft loss of weight, simplifies design cycle, optimizes aircraft aerodynamic performance, easier for installation, is reduced
Manpower and time cost improve working efficiency.
Description of the drawings

Specific implementation mode
As depicted in figs. 1 and 2, a kind of attachment device that civil aircraft hydraulic pressure product part is connect with fuselage, drain the oil 6 one end of pipeline company
It is connected to flange bracket 4, the other end is connected with connector 8, and there are two turbine and worm clips 5 for 6 excircle of pipeline of draining the oil suit；Described
4 structure of flange bracket is：1 excircle of flange head is set with detachable divided ring 2 and ring flange 3, and ring flange 3 is located at divided ring 2
Top, ring flange 3 are equipped with bolt 7, and bolt 7 runs through the upper and lower end face of ring flange 3, and bolt 7 is equipped with nut 9, and nut 9 is located at
3 lower section of ring flange.
The bolt 7 is more than two, is evenly distributed on ring flange 3.
As shown in figure 3,4 combination of two of flange bracket uses, bolt 7 runs through two ring flanges 3, two groups of divided rings
2 and 1 position of flange head correspond.
Flange combination holder is connected by ring flange with fuselage near opening, and PFA pipes one end is sleeved on flange combination holder
In thinner cylindrical outer wall, PFA pipes one end is fixed on flange bracket 4 with turbine and worm clip 5, the connector being connected with finished parts
It is connected with the overflow of hydraulic pressure product part or port of draining the oil, the PFA pipe other ends are sleeved on 8 one end of connector, will with turbine and worm clip 5
The PFA pipe other ends are fixed on connector 8.Turbine and worm clip 5 is fixed on the range on PFA pipelines in the relatively thin circle of flange bracket 4
It is sleeved on connector 8 in intersecting ranges with PFA pipelines in column length.
Above-described is only the preferred embodiment of the utility model.It should be pointed out that for the ordinary skill people of this field
For member, without departing from the principle of this utility model, several variations and modifications can also be made, also should be regarded as belonging to this
