Abstract
The utility model discloses a kind of vibration transducer, comprise housing and upper cover, piezoelectric ceramic devices and jacking block is provided with in described housing, described jacking block is arranged on the below of described piezoelectric ceramic devices in order to adjust the static pressure of piezoelectric ceramic devices, described jacking block is connected with adjustment volution through described housing, and described adjustment volution is outside equipped with test web member.The utility model by being arranged on piezoelectric ceramics in housing and the best detection position of jacking block adjustment, can effectively checkout equipment mechanical stress variable quantity thus obtain the change of electromotive force, electric charge, compact conformation, flexible operation.
Description
Technical field
The utility model relates to a kind of sensor, refers more particularly to a kind of vibration transducer, belongs to Electronic Testing field.
Background technology
Vibration transducer is the sensor for detecting impulsive force or acceleration, normally used is add the piezoelectric device that upper stress will produce electric charge, all more complicated installed by existing vibration transducer, needing to be fixed on the object of required test, needing vibration passing on the piezoelectric ceramic piece of the inside of sensor, to make piezoelectric ceramic piece produce deformation along with vibrating, thus induce electric charge, and piezoelectric ceramic piece will be made to produce deformation, will ensure that, when vibrating, potsherd is squeezed.And a lot of equipment is not necessarily provided with the installation site required for vibration transducer at present, also need punching on testee, clip etc. is installed, inconvenient operation, the variable quantity of the accurately checkout equipment mechanical stress of differing surely thus obtain the change of electromotive force, electric charge.
Utility model content
It is simple that the purpose of this utility model is just to provide a kind of structure to solve the problem, the vibration transducer of flexible operation.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises housing and upper cover, piezoelectric ceramic devices and jacking block is provided with in described housing, described jacking block is arranged on the below of described piezoelectric ceramic devices in order to adjust the static pressure of piezoelectric ceramic devices, described jacking block is connected with adjustment bolt through described housing, and described adjustment bolt is outside equipped with test web member.
Further, described jacking block is T-shape jacking block, and described T-shape jacking block and described inner walls are provided with waterproof washer.
Particularly, described upper cover is connected with pipe regulating screw nut by pressure regulating screw, is provided with described piezoelectric ceramics between described pipe regulating screw nut and described upper cover, and described upper cover is fixedly installed on the housing.
Further, described jacking block and described adjustment bolt are threaded connection.
Particularly, described test web member is magnet ring, and described magnet ring is sleeved on the outside of described adjustment bolt.
Further, described housing is provided with pilot hole and bolt.
The beneficial effects of the utility model are:
The utility model by being arranged on piezoelectric ceramics in housing and the best detection position of jacking block adjustment, can effectively checkout equipment mechanical stress variable quantity thus obtain the change of electromotive force, electric charge, compact conformation, flexible operation.
Accompanying drawing explanation
Fig. 1 is cut-open view of the present utility model;
Fig. 2 of the present utility modelly partly cuts open schematic perspective view;

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As illustrated in fig. 1 and 2, the utility model comprises housing 2 and upper cover 5, piezoelectric ceramic devices 3 and jacking block 7 is provided with in described housing 2, described jacking block 7 is arranged on the below of described piezoelectric ceramic devices 3 in order to adjust the static pressure of piezoelectric ceramic devices 3, described jacking block 7 is connected with adjustment bolt 10 through described housing 2, and adjustment bolt 10 is outside equipped with test web member.Described jacking block 7 is T-shape jacking block, described T-shape jacking block and described housing 2 inwall are provided with waterproof washer 1, described upper cover is connected with pipe regulating screw nut 41 by pressure regulating screw 4, be provided with described piezoelectric ceramics between described pipe regulating screw nut 41 and described upper cover 5, described upper cover is fixedly installed on the housing.
As shown in Figure 2, described housing 2 is provided with the ring 1 that is tightly connected, described housing 2 is provided with pilot hole 6 and bolt 9, described jacking block 7 is threaded connection with described adjustment bolt 10.
Because water supply pipe is arranged on underground, and inconvenience is punched on official road, and by mounting meanss such as clips, described test web member is magnet ring 8, and described magnet ring 8 is sleeved on the outside of described adjustment bolt 10, and magnet ring can directly be adsorbed on testee.The vibration signal of the various steel pipe of test that can be easy or dynamic equipment, test web member can be also gummed ring or solenoid, avoids causing damage to equipment under test.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included in protection domain of the present utility model.
