Embodiment
The embodiment 1 of jaw locking device shown in Fig. 1-4, has first connecting base 1, second connecting base 2 and is connected in the rod assembly between first, second connecting base.First connecting base 1 is used to be fixed on the internal face of corresponding position in the airplane equipment storehouse, and second connecting base 2 is used for fixing and is installed on the aircraft corresponding equipment frame; During use, first, second connecting base is connected drawing the equipment frame at second connecting base place, thereby be provided for the power that balance vector and lateral load are transmitted, the stable operation of airborne equipment on the assurance equipment frame for it through rod assembly; Rod assembly comprises through first hinging shaft 3 and is articulated on first connecting base 1 pull bar 4 and is articulated in the ears jaw 7 on second connecting base 2 through second hinging shaft 5; Wherein be provided with sliding bearing between second hinging shaft 5 and second connecting base 2, first hinging shaft 3 and second hinging shaft 5 are parallel to each other; Pull bar 4 has an internal thread segment away from an end of first connecting base 1; Ears jaw 7 also has an internal thread segment away from an end of second connecting base 2; Be connected through a connector element between pull bar 4 and the ears jaw 7; Connector element is a stud 8, and the two ends of stud 8 are respectively equipped with the opposite thread section of rotation direction and between two ends, are provided with and are used to supply to control or be used for only revolving the operating lever 9 that cooperates with instrument, and operating lever 9 adopts and is fixedly arranged on the nut on the stud; Stud 8 thread section through its two ends respectively with pull bar, ears jaw on the internal thread segment screw-thread fit; Because the rotation direction of the screw thread at the two ends of stud 8 is opposite; So when the turn stud, the internal thread segment of the precession simultaneously of its two ends or back-out pull bar and ears jaw; Between its operating lever 9 and pull bar 4, be provided with locking nut 10 on the stud 8; Also press between locking nut 10 and the pull bar and be provided with self-locking pad 6; When regulating stud to correct position; Through the locking nut of screwing pull bar and stud are tentatively locked, then with the two ends of self-locking pad 6 respectively bending be connected on pull bar and the stud, thereby further lock pull bar and stud.
During use; At first described first, second connecting base is fixedly arranged on the corresponding position; The corresponding end of described pull bar is articulated on described first connecting base; Described second connecting base is fixedly arranged on the corresponding equipment frame; Be connected with described ears jaw through the other end of described connector element with said pull bar, concrete connection procedure is following: 1) with the two ends of described stud precession pull bar and ears jaw and reach the setting pretightening force respectively, guarantee to be between axis and the Y axle (see figure 3) of pull bar the angle of 15-20 degree simultaneously; 2) the described locking nut of turn is with the relative position locking of described pull bar and stud; 3) with the two ends bending respectively of described self-locking pad, wherein an end is connected on the pull bar, and the other end is connected on the stud and gets final product.If the pull bar and the length of ears jaw integral body and the distance between two connecting bases do not wait, then only need come the length of regulating tie bar assembly to get final product in the above-mentioned assembly process through the described connecting sleeve of turn, easy to adjust; In addition because said first, second hinging shaft is parallel to each other, so rod assembly can only to aircraft apply along pull rod shaft to load, thereby effectively controlled the stressed of each parts of aircraft, avoid it to deform or damage; The impact that the angle that is the 15-20 degree between the axis of described pull bar and the Y axle has then avoided the load transition is fixedly connected with first connecting base aircraft on the transmitted load direction position to produce; Because therefore the length-adjustable of pull bar has also reduced the requirement to the machining accuracy of each member widely, has reduced cost of production.
In the foregoing description, described connector element can also adopt two ends to have the swivel nut of the opposite internal thread of rotation direction, in such cases, must corresponding external thread section be set in the corresponding end of said pull bar and ears jaw; Can also between said stud and pull bar and ears jaw, locking nut be set all; Described ears jaw can also replace with monaural or many ears jaw.
The embodiment 1 of rod assembly, as shown in Figure 4, identical with the structure of pull bar among the embodiment 1 of above-mentioned jaw locking device, will not give unnecessary details here.
