Claims

[Scope of utility model registration request]

(1) A screw depth measuring device that is provided with the following conditions A, B, C, and D. (A) Shaft body 1 inserted into screw hole 4 which is the object to be measured
, a contactor 2 attached to the shaft body 1 and screwed into the threaded surface of the threaded hole 4 to detect the maximum thread depth;
The shaft body 1 is configured with a guide 3 that guides the shaft body 1 so that it can rotate along the striations of the shaft body 1. (B) The shaft body 2 is sufficiently longer than the depth of the screw hole 4, and is provided with means for reading the depth position of the tentacle 2 in the axial direction. (C) The two tentacles each have a point that engages with a part of the screw hole 4, and are attached to the tip of the shaft body 1 so as to protrude in a radial direction. (D) The guide 3 rotatably and slidably guides the shaft 1 at a position concentric with the screw hole 4.

(2) The tentacle 2 is a cylindrical body whose outer circumferential surface has a threaded surface into which the four screw holes are screwed, and the contactor 2 is provided at a portion of the circumference of the cylindrical body so that the threaded surface is threaded into the part of the circumference of the cylindrical body. The screw depth measuring device according to claim (1) of the utility model registration claim, characterized in that the screw depth measuring device has a shape in which the thread depth is left in place and other parts are cut off.

(3) The screw according to claim (1) of the utility model registration, characterized in that the feeler 2 is a needle-like body 21 having a sharp point 211 sufficient to enter the thread trough of the screw hole 4. Depth measuring device.

(4) Thread depth according to claim (1) of the utility model registration claim, characterized in that a feeding device for feeding the precursor contactor 2 in the radial direction within the screw hole 4 is attached to the shaft body 1. measuring device.

(5) The screw depth measuring device according to claim 1, which is a registered utility model, characterized in that the guide 3 is provided with a spring 7 that is tensioned in the screw hole 4.
