[0002] An aircraft's hydraulic system is a crucial component, powering various aircraft movements and operations. Hydraulic pipes are a crucial component of the system, responsible for transporting hydraulic oil from the pump to the various actuators and returning the oil from the actuators to the hydraulic tank. Hydraulic pipes are located throughout the aircraft, spanning large distances. When hydraulic oil flows through these pipes, it generates pulsating pressure, causing the hydraulic lines to vibrate. Vibrating hydraulic pipes are prone to leaks and ruptures, and in severe cases, can damage the aircraft structure.

[0018] The utility model proposes a pipe clamp for installing aircraft hydraulic pipes, and the specific solution adopted is:

[0019] The components of this aircraft hydraulic pipe installation clamp are as follows: Figure 1 As shown in the figure, the pipe clamp mainly consists of six parts: housing, knob, moving slider, spring, rotating buckle, and cover. The housing is provided with knob mounting boss, spring mounting boss, rotating buckle mounting boss and guide groove.

[0020] Pipe clamp assembly drawing Figure 2 、 Figure 3As shown, the knob is installed on the knob mounting boss, and the knob can rotate around the knob mounting boss at a certain angle; the motion slider is installed in the guide groove, and the motion slider can slide in the guide groove; the spring is installed on the spring mounting boss; the rotary buckle is installed on the rotary buckle mounting boss, and the rotary buckle can rotate 90 degrees around the rotary buckle mounting boss.

[0021] Use rivets to install the pipe clamp on the aircraft structure. After the hydraulic pipe is installed in place, the pipe clamp is in a locked state. Figure 4 As shown in Figure 2, the vibration loads of the hydraulic pipes are transferred to the aircraft structure through the pipe clamps.

[0022] When using, select a standard size pipe clamp according to the diameter of the hydraulic pipe to be fixed, and connect the pipe clamp to the body structure with rivets. The steps for connecting the pipe clamp are as follows:

[0023] 1. Rotate the knob, which presses the slider to move along the guide groove. At the same time, the slider compresses the spring and opens the rotating buckle to the required angle. At this time, the pipe clamp is in the open state.

[0024] 2. Install the hydraulic pipeline that needs to be fixed on the pipe clamp;

[0025] 3. Press the rotating buckle, and when the spring returns to its natural state, the sliding block is compressed and moves, and the sliding block slides into the rotating buckle. At this time, the pipe clamp enters the locked state.

[0026] After the hydraulic pipe is installed in place, the assembly diagram is as follows Figure 4 As shown, when the hydraulic pipeline needs to be maintained or replaced, repeat the above steps.
