Screw mechanism for adjusting an angle of an antenna module and related antenna system
A screw mechanism for adjusting an angle of an antenna module is disclosed in the present invention. The screw mechanism includes a screw rod. The screw rod includes a rod portion. A thread is formed on a first area of the rod portion. An annular protrusion is formed on a second area of the rod portion, and an outer diameter of the annular protrusion is greater than an outer diameter of the rod portion. The screw rod further includes a handle disposed on an end of the rod portion adjacent to the second area. The screw mechanism further includes an accommodating component whereon a sunken part is formed. The sunken part is for accommodating the annular protrusion of the screw rod. The screw mechanism further includes a screw having a side hole. The screw is installed on the first area of the screw rod and moves along the thread.
1. A screw mechanism comprising:
a screw rod comprising:
a rod portion, a thread being formed on a first area of the rod portion, an annular protrusion being formed on a second area of the rod portion, and an outer diameter of the annular protrusion being greater than an outer diameter of the thread; and
a handle disposed on an end of the rod portion adjacent to the second area;
an accommodating component whereon a sunken slot is formed, the sunken slot being for rotatable and detachably accommodating the annular protrusion of the screw rod; and
a screw having a side hole, the screw being installed on the first area of the screw rod for moving along the thread of the screw rod to adjust relative position between the screw and the accommodating component when the screw rod is rotated.
2. The screw mechanism of claim 1 , wherein the screw rod further comprises a dial connecting to the handle of the screw rod.
3. The screw mechanism of claim 2 , wherein the dial is integrated with the handle of the screw rod monolithically or the dial is a separate component for disposing on the handle of the screw rod.
4. The screw mechanism of claim 1 , wherein the screw rod does not move relative to the accommodating component when the screw rod is rotated.
5. An antenna system comprising:
a supporter;
an antenna module; and
a screw mechanism disposed between the supporter and the antenna module, the screw mechanism comprising:
a screw rod comprising:
a rod portion, a thread being formed on a first area of the rod portion, an annular protrusion being formed on a second area of the rod portion, and an outer diameter of the annular protrusion being greater than an outer diameter of the thread; and
a handle disposed on an end of the rod portion adjacent to the second area;
an accommodating component disposed on the supporter, a sunken slot being formed on the accommodating component for rotatable and detachably accommodating the annular protrusion of the screw rod; and
a screw having a side hole, the screw being disposed on the antenna module and installed on the first area of the screw rod for moving along the thread of the screw rod to adjust relative position between the screw and the accommodating component when the screw rod is rotated, so as to adjust an angle between the antenna module and the supporter.
6. The antenna system of claim 5 , wherein the screw rod further comprises a dial connecting to the handle of the screw rod.
7. The antenna system of claim 6 , wherein the dial is integrated with the handle of the screw rod monolithically or the dial is a separate component for disposing on the handle of the screw rod.
8. The antenna system of claim 5 , wherein the screw rod does not move relative to the accommodating component when the screw rod is rotated.
