Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to the following stated:
As Figure 1-4, the stringer card of equipment is fixed on a kind of Airbus Aircraft stringer, it includes deck 1, fixed block 2 and screw 3, the trapezoidal shape in cross section of described deck 1, the top of deck 1 is provided with the screwed hole B4 for installing equipment, being provided with groove 5 on the inclined-plane of deck 1, groove 5 takes the shape of the letter U shape, is provided with through hole 6 in groove 5.As shown in Figure 2 and Figure 4, the lower section on the basal surface of the deck 1 and inclined-plane that is positioned at deck 1 is provided with limited block 7 and heavy stand 8, U-lag 9 it is additionally provided with on the basal surface of deck 1, the U-lag 9 warp architecture for the top with aircraft stringer matches, U-lag 9 is arranged on the underface of screwed hole B4 and connects with screwed hole B4, heavy stand 8 is arranged between limited block 7 and U-lag 9, is provided with chamfering I10 between limited block 7 and heavy stand 8.As Figure 1-4, fixed block 2 is plate-shaped, and fixed block 2 is provided with screwed hole C11, and fixed block 2 is arranged between U-lag 9 with limited block 7 and is provided with chamfering II12 matched with chamfering I10 on the corner angle of limited block 7.As Figure 1-3, the top surface of fixed block 2 leans against on heavy stand 8 and chamfering II12 contacts with chamfering I10, fixed block 2 is fastened on deck 1 with screwed hole C11 through through hole 6 through screw 3, when along with when gradually tightening of screw 3, chamfering II12 is also gradually increased with the contact surface of chamfering I10, and the distance of fixed block 2 and the inwall of U-lag 9 is gradually shortened, thus the stringer being placed in U-lag 9 is pressed between the inwall of U-lag 9 and fixed block 2, achieve whole stringer card being fixed on stringer steadily, only equipment need to be connected with screwed hole B4 subsequently and just can be fixed on deck 1, and by rivet, equipment frame is fixed again without punching on stringer, and do not destroy the original structure of aircraft, there is mechanical strength high, easy feature is installed.
The work process of the present invention is as follows: as illustrated in figs. 5-7, first U-lag 9 is buckled in the tip portion of stringer, the top surface making fixed block 2 again leans against on heavy stand 8 and makes chamfering II12 of fixed block 2 to contact with chamfering I10, then screw 3 is made to sequentially pass through through hole 6 and be connected with screwed hole C11, along with gradually tightening of screw 3, stringer is by between fixed block 2 inwall being stuck in fixed block 2 and U-lag 9 tightly, therefore, whole stringer card is by being fixed on stringer steadily, equipment only need to be connected with screwed hole B4 through screw and can be fixed on deck 1, it is achieved thereby that the Fast Installation of equipment.
The above is only the preferred embodiment of the present invention, it is to be understood that the present invention is not limited to form disclosed herein, it is not to be taken as the eliminating to other embodiments, and can be used for other combinations various, amendment and environment, and can be modified by above-mentioned teaching or the technology of association area or knowledge in contemplated scope described herein.And the change that those skilled in the art are carried out and change are without departing from the spirit and scope of the present invention, the most all should be in the protection domain of claims of the present invention.
