Abstract

An electronic screw with an electronic torque display is disclosed. The screw includes a body and a torque sensing element. The body has a threading head, a shank connected to the threading head and a recess located on the side wall of the shank. The torque sensing element is disposed in the recess and detected the torque value of the electronic screw. The torque sensing element is electrically connected to the electronic torque display, wherein the electronic torque display displays the torque value that detected from the torque sensing element.

First claim

What is claimed is:

1. An electronic screw, which is cooperated with an electronic torque display for measuring a torque value, the electronic screw comprising:
a body comprising:
a threading head; and
a shank connected to the threading head, wherein the shank comprises:
a neck portion, one end of the neck portion connected to the threading head, wherein the neck portion does not have a thread; and
a threading portion connected to the other end of the neck portion;

a recess located on a side wall of the shank, wherein one third of a volume of the recess is located on the neck portion, and two thirds of the volume of the recess is located on the threading portion; and

a torque sensing element disposed in the recess and electrically connected to the electronic torque display, wherein one third of a portion of the torque sensing element is located within the neck portion and two thirds of the portion of the torque sensing element is located within the threading portion.

2. The electronic screw of claim 1 , wherein the volume of the recess is greater than or equal to a volume of the torque sensing element.

3. The electronic screw of claim 1 , wherein the threading head of the body comprises a threading head recess, and the recess comprises a connecting channel connected to the threading head recess.

4. The electronic screw of claim 3 , wherein the threading head recess comprises an electronic leg.

5. A screw torque sensing device comprising:
a body comprising:
a threading head; and
a shank connected to the threading head, wherein the shank comprises:
a neck portion, one end of the neck portion connected to the threading head, wherein the neck portion does not have a thread; and
a threading portion connected to the other end of the neck portion;

a recess located on a side wall of the shank, wherein one third of a volume of the recess is located on the neck portion, and two thirds of the volume of the recess is located on the threading portion;

a electronic torque display movably mounted on the threading head; and
a torque sensing element disposed in the recess and electrically connected to the electronic torque display, wherein one third of a portion of the torque sensing element is located within the neck portion and two thirds of the portion of the torque sensing element is located within the threading portion.

6. The screw torque sensing device of claim 5 , wherein the electronic torque display comprises a light emission source, and the light emission source is set according to an illuminating state.

7. The screw torque sensing device of claim 6 , wherein the light emission source is a light emitting diode.

8. The screw torque sensing device of claim 5 , wherein the electronic torque display is for displaying a torque value of the torque sensing element.

9. The screw torque sensing device of claim 5 , wherein the electronic torque display is for displaying a torque value from the torque sensing element with an audio.

10. The screw torque sensing device of claim 5 , wherein the torque sensing element is below a side wall surface of the shank, and the screw torque sensing device further comprises a cover with a waterproof pad disposed on the recess for covering the torque sensing element.
