According to FIG. 1 to FIG. 5, the present invention provides a kind of sensor clips for airplane hydraulic pressure conduit vibration measurement
Component, comprising: clip 1, sensor support base 2, clamp nut 3, cushion block 4.
On clip ontology between two circumferential claws 7 of clip 1, it is equipped with radially boss 8 outstanding, boss
8 radial section offers through-hole in the middle part of boss 8,8 bottom surface of boss is led with hydraulic at the arc-shaped with 5 concentric of hydraulic pipe
Gap is formed between 5 outer wall of pipe, clip 1 being capable of diastole and contraction based on environment temperature, realization release hydraulic pipe 5 or clamping
Hydraulic pipe 5.
Sensor support base 2 is including pedestal 2-1 and the screw rod 2-2 being arranged on pedestal 2-1, screw rod 2-2 through boss 8
Through-hole, pedestal 2-1 adaptation are arranged in the gap formed between 5 outer wall of 8 bottom surface of boss and hydraulic pipe.
It is understood that determining the overall dimensions of clip 1 according to the diameter of hydraulic pipe 5, the circumferentially deploying of clip 1 is long
Degree is less than or equal to the circumferential length of hydraulic pipe 5, and the width of clip 1 is the quarter turn length and sensor 6 of hydraulic pipe
Both diameter or widths compare obtained smaller value, and the width of clip 1 is equal to or more than the width of sensor support base 2.Clip 1
Radially the length of run of boss outstanding is the quarter turn length of hydraulic pipe.Between boss 8 and hydraulic pipe 5
