Description
Technical field
The utility model relates to a kind of ultrasonic flux transducers, belong to transducer technology field.
Background technique
Existing ultrasonic flux transducer mostly uses the side of multiple groups part gluing knot piezoelectric ceramics and stainless steel cap or shell
Formula connection, this mode make the gap and bubble that occur more or less between piezoelectric ceramics and stainless steel cap or shell, with
The variation internal gas dilation of temperature drives gap between stainless steel cap and piezoelectric ceramic piece gradually to expand, ultrasonic flow
Energy converter transmission signal strength gradually weakens, and piezoelectric ceramic piece is thoroughly detached from stainless steel cap for a long time, and ultrasonic flow changes
Energy device is also eliminated, and seriously affects the service life of ultrasonic flux transducer.
Utility model content
In view of the above defects of the prior art, the utility model provides a kind of ultrasonic flux transducer, can
Service life to solve the problems, such as existing ultrasonic flux transducer is lower.
The utility model is achieved by the following technical solution：A kind of ultrasonic flux transducer, including shell and
Piezoelectric ceramic piece further includes fixing piece, and the inner circumferential of the shell is equipped with internal screw thread, and one end of shell is equipped with the signal surface of emission, separately
One end is hatch frame, and the periphery of the fixing piece is equipped with the external screw thread matched with shell internal screw thread, is set on the fixing piece
There are threading hole and fastener hole, the piezoelectric ceramic piece is pressed in shell by fixing piece.
Further, rubber buffer, the rubber buffer are equipped between the fixing piece and the piezoelectric ceramic piece
It is equipped with threading hole.
Further, the shell is monolithic construction, can improve the waterproof performance of energy converter well.
Further, the shell is copper shell.
Further, piezoelectric ceramic piece signal uses asphalt mixtures modified by epoxy resin after threading hole extraction by the signal wire of piezoelectric ceramic piece
Rouge glue encapsulating, is further ensured that stability when work.
In ultrasonic flux transducer described in the utility model, cooperated using shell internal screw thread and fixing piece external screw thread
Mode is fastened by fastener hole and squeezes piezoelectric ceramic piece, and piezoelectric ceramic piece signal is drawn by the conducting wire of piezoelectric ceramic piece from threading hole
Out, make to completely attach between the surface of emission of piezoelectric ceramic piece and shell, so that ultrasonic flux transducer will not be by temperature
Change and signal occurs and weakens phenomenon, improves the stability and anti-interference ability of signal transmission.
Detailed description of the invention

Specific embodiment
The utility model is further described below by non-limiting embodiment and in conjunction with attached drawing：
The utility model embodiment provides a kind of ultrasonic flux transducer, including shell 1 and piezoelectric ceramic piece 4, also
Including fixing piece 6, the inner circumferential of the shell 1 is equipped with internal screw thread 2, and one end of shell 1 is equipped with the signal surface of emission 3, and the other end is to open
Mouth structure, the periphery of the fixing piece are equipped with the external screw thread 8 matched with shell internal screw thread, and the fixing piece is equipped with threading hole
7 and fastener hole 9, the piezoelectric ceramic piece 4 is pressed in shell by fixing piece 6.
Rubber buffer 5 is equipped between the fixing piece and the piezoelectric ceramic piece, the rubber buffer is equipped with and wears
String holes.
The shell is monolithic construction, using copper shell.The signal wire that piezoelectric ceramic piece signal passes through piezoelectric ceramic piece
10 use epoxide-resin glue encapsulating after threading hole extraction.
The foregoing is merely specific embodiment of the present utility model, are not intended to limit the utility model, for
For those skilled in the art, various modifications and changes may be made to the present invention.All spirit and original in the utility model
Any modification, equivalent replacement, improvement and so within then, should be included within the scope of protection of this utility model.
