Each of described acceleration transducer contiguous block 4 is provided with threaded hole.
The threaded hole of described U-shaped snap ring base 2 center is identical with the threaded hole that acceleration transducer contiguous block 4 is arranged.
Use procedure of the present utility model is: during experiment, the acceleration transducer circular fixture this being used for measuring channel vibration moves to the horizontal or vertical position of the measurement point that needs are measured, be stuck in pipeline with U-shaped snap ring 1 and need measured place, tighten the screw on U-shaped snap ring 1, U-shaped snap ring 1 is fastened on pipeline, because acceleration transducer contiguous block 4 is provided with multiple threaded hole, user can be according to actual needs, optionally on acceleration transducer contiguous block 4 all directions face on acceleration transducer 5 be installed carry out testing, such as, on acceleration transducer contiguous block 4 respectively can X in connection space, Y, the acceleration transducer 5 in Z axis three directions, to be convenient for measuring the vibrating numerical in a measurement point three directions.
In order to cost-saving, if when acceleration transducer 5 only has one, when the vibration data of different directions will be tested, first can survey a direction, acceleration transducer 5 dismantled to be installed on another direction that need test again and continues to test.
The beneficial effects of the utility model are:
1, solve acceleration transducer and difficult problem is installed on the cylindrical structures such as pipeline, solve the repeatability that acceleration transducer is installed simultaneously;
2, the utility model is without the need to buying sensor pad in practicality, can not destroy equipment under test, and not fragile acceleration transducer, saves man power and material greatly;
3, the utility model structure is simple, easy to manufacture, and is easy to carry;
4, connect closely, ensure the quality of data of test;
5, common one direction acceleration transducer can be used to measure the vibration data of multiple directions at same measurement point, decrease the quantity purchase of sensor, reduce experimental cost.
