[0034] The working principle and usage process of the present utility model: During use, a structure including a central control bin and a protective cover is combined together. At the four corners of the top of the central control bin, there are first mounting plates, on which columns are fixedly connected. The top of the columns is fixedly connected with sliding rods, and the top of the sliding rods is fixedly connected with conical heads. The outer side of the sliding rods is slidably connected with conical bottom heads. On one side of the top of the central control bin, elastic telescopic rods are symmetrically and fixedly connected, and their tops are fixedly connected with a support plate. At the four corners of the bottom of the protective cover, there are second mounting plates, and locking cylinders are fixedly connected to their bottoms. Inside the locking cylinders, chutes are symmetrically arranged, and moving rods are slidably connected inside the chutes. One end of the moving rod is fixedly connected with a buckle, and a spring is arranged on its outer side. Then, when repairing the internal lines of the aircraft, the operator only needs to press the protective cover to slide the buckle below the conical head. Due to the elastic effect of the connection between the moving rod and the spring, the buckle will slide below the conical bottom head. Then, the operator can lift it outwards through the hand-holding groove provided on the protective cover, so that the conical bottom head fits with the conical head to form a conical structure. At this time, the buckle will slide outwards along the fitting hypotenuse, and the operator can quickly disassemble the protective cover to repair the internal lines of the aircraft. On the contrary, by pressing the protective cover and pushing the buckle towards the conical head direction, the conical bottom head can be separated from the conical head, achieving the effect of quickly installing the protective cover. In addition, inclined grooves are formed at the top of the columns, and the first mounting plates and the columns are fixedly connected to the central control bin through bolts, enhancing the structural stability. The support plate fits on the surface of the protective cover, enabling the protective cover to better maintain its shape. A hand-holding groove is formed on one side of the protective cover, facilitating the operator's lifting operation. The second mounting plates and the locking cylinders are fixedly connected to the protective cover through bolts, ensuring the stability of the buckle mechanism. The spring is fixedly connected between the chute and the buckle, providing an elastic force. A limiting nut is threadedly connected to the outer end of the moving rod, restricting the sliding range of the moving rod. A wiring board is fixedly connected to the top of the central control bin, and wiring grooves are formed in the top of the wiring board, facilitating the layout of the lines. Through the above working principle, the protective cover for repairing the internal lines of the aircraft can achieve quick disassembly and installation, facilitating the repair work of the internal lines of the aircraft and improving work efficiency and safety.

[0035] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
