Abstract

A dust proof structure for a stress-sensible screw is provided. The dust proof structure includes a sensing screw, a head, a dust proof boot and a displayer. The sensing screw includes a base and at least one exposed lead, and the exposed lead is located in the base and transmits a stress signal. The head includes a lead base, the head is fitted with the base, and the exposed lead is detachably connected to the lead base. The dust proof boot is disposed on the head, and sleeves a connecting portion between the lead base and the exposed lead. The displayer is electrically connected w the had for displaying the stress signal.

First claim

What is claimed is:

1. A dust proof structure for a stress-sensible screw, comprising:
a sensing screw comprising a base and at least one exposed lead that is located in the base and transmits a stress signal;
a head comprising a lead base and fitted with the base, wherein the exposed lead is detachably connected to the lead base;
a dust proof boot disposed on the head and sleeving a connecting portion between the lead base and the exposed lead; and
a displayer electrically connected to the head for displaying the stress signal;
wherein the dust proof boot comprises a connecting portion, an expandable portion and a withstanding portion, and the connecting portion is connected to the head; when the head is fitted with the sensing screw. the expandable portion is expanded relative to the base, and the withstanding portion withstands a bottom of the base, thereby sleeving the exposed lead.

2. The dust proof structure of claim 1 , wherein the head is detachably fitted with the base.

3. The dust proof structure of claim 1 , wherein the base is protruded for being fitted with outside of the head or the base is dented for being fitted with inside of the head.

4. The dust proof structure of claim 1 , wherein the expandable portion is bellows shaped.

5. The dust proof structure of claim 1 , wherein the displayer is connected to the head by a connecting wire.

6. The dust proof structure of claim 1 , wherein the displayer is wirelessly connected to the head.

7. The dust proof structure of claim 6 , wherein the head further comprises a wireless transceiver.

8. The dust proof structure of claim 7 , wherein the wireless transceivers is connected to the displayer through an Infrared, a Bluetooth or a NFC.

9. A dust proof structure for a stress-sensible screw, comprising:
a sensing screw for sensing and transmitting a stress signal;
a head fitted with the sensing screw;
a dust proof boot sleeving a connecting portion between the head and the sensing screw; and
a displayer electrically connected to the head for displaying the stress signal;
wherein the dust proof boot comprises a connecting portion, an expandable portion and a withstanding portion, and the connecting portion is connected to the head; when the head is fitted with the sensing screw, the expandable portion is expanded relative to the base, and the withstanding portion withstands a bottom of the base, thereby sleeving the exposed lead.

10. The dust proof structure of claim 9 , wherein the head is detachably fitted with the base.

11. The dust proof structure of claim 9 , wherein the base is dented or protruded; when the base is dented, the head is connected with inside of the base, and when the base is protruded, the head is connected with outside of the base.

12. The dust proof structure of claim 9 , wherein the expandable portion is bellows shaped.

13. The dust proof structure of claim 9 , wherein the displayer is connected to the head by a connecting wire.

14. The dust proof structure of claim 9 , wherein the displayer is wirelessly connected to the head.

15. The dust proof structure of claim 14 , herein the head further comprises a wireless transceiver.

16. The dust proof structure of claim 15 , wherein the wireless transceivers is connected to the displayer through an Infrared, a Bluetooth or a NFC.
