The specific embodiment
Be used to connect the embodiment 1 of the bindiny mechanism of floor crossbeam and electronic equipment rack; Shown in Fig. 1-4; Have on first Connection Block 1 and the floor crossmember 3 of second Connection Block, 2, the first Connection Blocks 1, on the column of second Connection Block 2 for fixing to the electronic equipment rack of aircraft for fixing to aircraft; First Connection Block 1 have base plate 1-1, vertically be fixed on the riser 1-2 on the base plate 1-1 and be arranged at riser 1-2 and base plate 1-1 between two strengthen gusset 1-3; Wherein base plate 1-1 and riser 1-2 and two strengthen one jiao of box of the common formation of gusset 1-3; Base plate 1-1 is provided with penetrating pilot hole; Riser 1-2 is provided with first connecting bore, 5, the first connecting bores 5 be used for packing into bolt, screw or rivet (present embodiment is a rivet) and first Connection Block 1 fixedly is assemblied in a side of floor crossbeam 3; Second Connection Block 2 has swivel nut 2-1 and is fixedly connected on the connecting panel 2-2 on the circumferential side of swivel nut 2-1; Has second connecting bore 6 on the connecting panel 2-2; Second connecting bore 6 be used for packing into bolt, screw or rivet (present embodiment is a rivet) fixedly is assemblied in second Connection Block 2 the column (not shown) of the electronic equipment rack of aircraft; Have penetrating tapped bore on the swivel nut 2-1 and be equipped with pilot bar 7 through said tapped bore; Pilot bar 7 inserts axially cooperating with said pilot hole guiding in the pilot hole on first Connection Block 1 and along pilot bar 7 away from an end of second Connection Block 2; Be provided with block 7-1 between the two ends of pilot bar 7 and pass through said block 7-1 and cooperate with the swivel nut block; In the present embodiment, block 7-1 adopts hexagonal nut shape, and its outer peripheral face is formed for only revolving with corresponding instrument (like spanner) radial facing that ends of cooperation; Pilot bar 7 passes the tapped bore of swivel nut 2-1 and is provided with self lock nut 8 with an end of swivel nut 2-1 screw thread fit; Self lock nut 8 is used to prevent between pilot bar 7 and the swivel nut 2-1 to take place because of getting loose relative displacement; Pilot bar 7 is polished rod and is arranged with retracing spring 9 with the end that first Connection Block, 1 guiding cooperates; Because retracing spring 9 is arranged between first Connection Block 1 and second Connection Block 2; Therefore when deformation takes place in vertical (Fig. 3 left side arrow direction) for the floor crossmember 3 of aircraft, can recover deformation, when the instantaneous drastic change of floor beam 3 generations of aircraft through the pressure of retracing spring 9; Can prevent that it is damaged through slow 9 the deformation of retracing spring towards crossbeam.
Because the said bindiny mechanism that is used to connect floor crossbeam and electronic equipment rack comprises first, second Connection Block that is used for being fixed on respectively on floor crossbeam and the electronic equipment rack; Be installed with pilot bar on one in said first, second Connection Block, another is provided with the pilot hole that axially cooperates with the pilot bar guiding along said pilot bar; Therefore; Can in described first, second Connection Block be fixed on the floor crossbeam in use; Another is fixed on the electronic equipment rack of aircraft; Pilot bar can be used for transmitting the load of vector and side direction, when floor crossbeam generation vertical deformation, compensates the deformation of floor crossbeam through relatively moving of said pilot bar and pilot hole; Avoid deformation loading transfer with the floor crossbeam to electronic equipment rack, having solved existing bindiny mechanism can be with the problem of vertical deformation loading transfer to the electronic equipment rack of floor crossbeam; In addition, because therefore the electronic equipment rack of aircraft can not design the load that need consider the distortion of aircaft configuration frequently and increase in the shock effect that receives the floor crossbeam, this has then reduced the weight of electronic equipment rack.
In the foregoing description; The described oppositely use of bindiny mechanism that is used to connect floor crossbeam and electronic equipment rack; Being about to said first Connection Block is fixed on the electronic equipment rack of aircraft; Described second Connection Block is arranged on the floor crossmember of aircraft, and certainly, said pilot bar need be done adaptive putting upside down; Described first, second Connection Block can also adopt fixed block; Said pilot bar can also be connected with said second permanent seat welding or flange; Described retracing spring can also omit.
