Bolt tension gauging device
A bolt tension gauging device is provided. The bolt tension gauging device includes a sensing bolt, a head and a displayer. The sensing bolt is for transmitting a stress signal. The head is for fitting with the sensing bolt. The displayer is connected to the head for displaying the stress signal.
1. A bolt tension gauging device, comprising:
a sensing bolt having a head portion and a thread portion, the thread portion has a recess on a peripheral surface, and a stress sensing member is configured to fit onto the recess for sensing a stress applied to the thread portion and transmitting a stress signal;
a head for detachably fitting with the sensing bolt;
a wireless transceiver disposed on the head and transmitting the stress signal received from the sensing bolt; and
a displayer wirelessly connected to the wireless transceiver for displaying the stress signal received from the wireless transceiver.
2. The bolt tension gauging device of claim 1 , wherein the sensing bolt comprises a base for fitting with the head.
3. The bolt tension gauging device of claim 2 , wherein the base is protruded or dented.
4. The bolt tension gauging device of claim 3 , wherein at least one first exposed lead is disposed on the base, at least one second exposed lead is disposed on the head, and the first exposed lead is connected with the second exposed lead for transmitting the stress signal.
5. The bolt tension gauging device of claim 1 , wherein the wireless transceiver is connected through an Infrared, a Bluetooth or a NFC.
6. A bolt tension gauging device, comprising:
a sensing bolt having a head portion and a thread portion, the thread portion has a recess on a peripheral surface, and a stress sensing member is configured to fit onto the recess for sensing a stress applied to the thread portion and transmitting a stress signal;
a head for detachably fitting with the sensing bolt; and
a displayer connected to the head for displaying the stress signal.
7. The bolt tension gauging device of claim 6 , wherein the sensing bolt comprises a base for fitting with the head.
8. The bolt tension gauging device of claim 7 , wherein the base is protruded or dented.
9. The bolt tension gauging device of claim 7 , wherein in at least one first exposed lead is disposed on the base, at least one second exposed lead is disposed on the head, and the first exposed lead is connected with the second exposed lead for transmitting the stress signal.
10. The bolt tension gauging device of claim 6 , wherein the displayer further comprises a solar cell plate.
