Abstract

An ultrasonic probe jig includes a leaf spring, a support member, a mounting mechanism, and a regulating member. The leaf spring member is brought into contact with the upper surface of an ultrasonic probe to be located on an object to be examined. The support member supports a peripheral portion of the leaf spring member. The mounting mechanism pivotally mounts a support rod coupled to a control device on the support member. One end of the regulating member is mounted to the support rod and the other end thereof is engaged with the support member. The regulating member regulates pivotal movement of the support member.

Claims

1. An ultrasonic probe jig comprising:

a leaf spring member brought into contact with an upper surface of an ultrasonic probe to be located on an object to be examined;

a support member for supporting a peripheral portion of said leaf spring member;

a mounting mechanism for pivotally mounting a support rod coupled to a control device on said support member; and

a regulating member one end of which is mounted to said support rod and the other end of which is engaged with said support member, said regulating member being adapted to regulate pivotal movement of said support member.

2. A jig according to claim 1, wherein said support member comprises an arm, a central portion of which is constituted by a flat portion and distal portions of which are bent downward.

3. A jig according to claim 2, wherein a pivot mechanism is mounted on said central portion of said arm to pivotally support said support rod.

4. A jig according to claim 2, wherein the other end of said support member is locked on the flat portion of said arm.

5. A jig according to claim 1, wherein said support member comprises arms having flat portions extending at three equal angular positions and distal portions bent downward.

6. A jig according to claim 1, wherein said support member comprises arms having flat portions extending at four equal angular positions and distal portions bent downward.

7. An ultrasonic jig assembly comprising:

a support rod member;

supporting means pivotally supported by said support rod member; and

ultrasonic jigs, each comprising a leaf spring member brought into contact with an upper surface of an ultrasonic probe to be located on an object to be examined, a support member for supporting a peripheral portion of said leaf spring member, a mounting mechanism for pivotally mounting a support rod coupled to a control device on said support member, and a regulating member one end of which is mounted to said support rod and the other end of which is engaged with said support member, said regulating member being adapted to regulate pivotal movement of said support member,

said ultrasonic jigs being pivotally mounted at both ends of said supporting means.

8. An assembly according to claim 7, wherein said supporting means is bent according to an arcuated shape of the object to be examined.
