Embodiment Construction

[0014] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. see Figure 1 to Figure 7 .

[0015] The present invention is mainly composed of the following parts: a stop gasket 1, a stop bolt 2 and an anchor bolt 3. The middle of the stop washer 1 is a circular arc surface 101 to match the circular track on the aircraft guide rail. Both sides of the stop washer 1 are rectangular planes 102, and both sides are provided with rectangular through holes. The stop bolt 2 is a bolt head with a round head, consisting of a polished rod with a rectangular cross-section and a circular threaded part. It is used in conjunction with the stop washer 1 in actual application to limit the movement of the equipment rack along the front and rear directions of the aircraft guide rail; The bolt head of bolt 3 is circular, and there are L-shaped through grooves symmetrically on both sides of the upper part, and its width ma...

Abstract

The invention relates to an engine room test equipment rack fixing adapter structure. The invention comprises a stopping washer, a stopping bolt and an anchor bolt; a circular arc surface in the middle of the stopper gasket is matched with a circular track on the aircraft guide rail, and two sides of the stopper gasket are rectangular planes; the stopping bolt is divided into a circular head bolthead, a polished rod with a rectangular cross section and a thread with a circular cross section from bottom to top; When in use, the stopping bolt and the stopping washer cooperate to limit the movement of the equipment rack in the front-back direction of the guide rail; the bolt head of the anchor bolt is circular, and L-shaped through grooves are symmetrically formed on both sides of the upperpart; In use, the two parallel vertical surfaces formed by the through grooves engage the anchor bolts on the inner wall of the aircraft guide rail to avoid rotation during bolt tightening. The invention can effectively borrow the internal plate slide rail of the aircraft cabin, fix the equipment rack through the transfer structure, avoid disassembling the internal structure of the engine cabin when installing the equipment rack, assemble quickly and reliably, and improve the assembly efficiency of the equipment rack by more than 80%.

Description

technical field [0001] The invention belongs to the aircraft structure technology, and relates to a fixed transfer structure for an engine room test equipment rack. Background technique [0002] Both the traditional equipment rack and the cabin floor adopt the method of borrowing the fasteners of the original cabin floor, which requires dismantling the fasteners on the original floor; Seat rail removal. The installation steps of the test equipment frame in the above method are complicated, and there are many procedures, and the aircraft cockpit seat needs to be disassembled, and the bolt holes are borrowed, which affects the use of parts such as the aircraft cockpit seat. Contents of the invention [0003] The purpose of the present invention is: the present invention provides a kind of transition structure, makes the connection between test equipment frame and aircraft utilize the slide rail track in the aircraft cockpit, realizes that the test equipment frame is fixed i...
