[0004] Although the above-mentioned miniaturized antenna used in 5G mobile communications has a movable structure on the outside of the retractable structure, which makes it easier to disassemble and assemble the antenna and reduces high-altitude operations, thereby making disassembly and assembly safer and more convenient for antenna maintenance, it still has the following shortcomings: in order to improve the stability of the antenna receiving signal, the antenna is usually installed higher. Therefore, when encountering severe weather with strong winds, the antenna will be easily blown off due to the high installation height, which will not only cause large economic losses, but also easily cause safety accidents.

[0005] To this end, a miniaturized antenna for communication is proposed. Summary of the invention

[0006] The object of the present invention is to provide a miniaturized antenna for communication, which can solve the problems raised in the above background technology by automatically controlling the driving mechanism to drive the mounting rod and the antenna to move downward and lower the center of gravity of the mounting rod and the antenna when the wind is strong.

[0009] The drive mechanism can be controlled to open and close by operating the control button. Starting the drive mechanism can drive the mounting rod to move up and down. By moving the mounting rod downward, the antenna can be installed on the mounting rod or the antenna on the mounting rod can be repaired. By moving the mounting rod and the antenna upward, the installation height of the antenna can be increased and the signal strength of the antenna can be increased. When the wind is strong, the control component can automatically control the drive mechanism to drive the mounting rod and the antenna to move downward and lower the center of gravity of the mounting rod and the antenna, thereby preventing the antenna from being blown off the mounting rod or breaking the mounting rod by strong winds, which not only improves the safety of the use of miniaturized antennas for communications, but also reduces the cost of using miniaturized antennas for communications. When the drive mechanism is powered off, the fixing mechanism will fix the mounting rod, which improves the stability of the installation of the mounting rod, the antenna and the miniaturized antenna for communications, thereby improving the use effect of the miniaturized antenna for communications.

[0011] When the driving motor is energized, it can drive the driving shaft, the first bevel gear, the second bevel gear, the rotating shaft and the rotating drum to rotate. The rotating drum is threadedly engaged with the mounting rod and the guide sleeve is limited. Therefore, the rotation of the rotating drum can drive the mounting rod and the antenna to move up and down. By moving the mounting rod downward, the antenna can be installed on the mounting rod or the antenna on the mounting rod can be repaired. By moving the mounting rod and the antenna upward, the installation height of the antenna can be increased and the signal strength of the antenna can be increased, thereby improving the use effect of the miniaturized antenna for communication.

[0013] When the wind is strong, the wind will blow the mounting rod, antenna and guide sleeve and drive the guide sleeve to squeeze the piezoelectric ceramic piece installed on the outer wall of the top end of the fixed rod. After the piezoelectric ceramic piece is squeezed, it will generate current and power the first solenoid valve. After the first solenoid valve is energized, it will close the circuit connected between the drive motor and the battery and start the drive motor to rotate forward. The forward rotation of the drive motor can drive the mounting rod, antenna and guide sleeve to move downward and lower the center of gravity of the mounting rod and antenna, thereby preventing the antenna from being blown off the mounting rod or breaking the mounting rod by strong winds, which not only improves the safety of using miniaturized antennas for communications, but also reduces the cost of using miniaturized antennas for communications.

[0017] When the driving motor is powered on, the first electromagnet will attract the slider and the plug block to shrink into the mounting groove, and the second electromagnet will attract the annular mounting plate and the limit rod to move downward to the bottom end of the rotating drum, so that the rotating drum can rotate freely and the mounting rod and the guide sleeve can move up and down freely. When the driving motor is powered off, the first spring will push the slider and the plug block to move due to the restoration of its own elastic force and push one end of the plug block to the outside of the fixed rod. At this time, one end of the plug block is inserted into the corresponding socket, so that the guide sleeve, the mounting rod and the antenna can be fixedly connected to the fixed rod and prevent the guide sleeve, the mounting rod and the antenna from sliding up and down; when the driving motor is powered off, the second spring will push the annular mounting plate and the limit rod to move upward due to the restoration of its own elastic force and push the top end of the limit rod to the upper side of the movable groove. At this time, the top end of the limit rod is inserted into the bottom end of the rotating drum, so that the rotating drum, the mounting rod and the antenna can be fixedly connected to the fixed rod and prevent the rotating drum, the mounting rod and the antenna from rotating, thereby improving the stability of the installation of the mounting rod, the antenna and the miniaturized antenna for communication, thereby improving the use effect of the miniaturized antenna for communication.

[0019] When the driving motor drives the guide sleeve to move upward, gas will be sucked into the guide sleeve through the exhaust pipe. When the driving motor drives the guide sleeve to move downward, the gas in the guide sleeve will be discharged through the exhaust pipe. The driving motor drives the mounting rod, antenna and guide sleeve to move upward to the top and after the driving motor is powered off, the guide sleeve will be filled with gas and sealed with a solenoid valve. After the interior of the guide sleeve is filled with gas, the overall strength of the guide sleeve will be improved, thereby preventing the guide sleeve from being flattened when wind force acts on the guide sleeve, thereby improving the use effect of the guide sleeve and the miniaturized antenna for communication.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When the wind is strong, the control component can automatically control the driving mechanism to drive the mounting rod and the antenna to move downward and lower the center of gravity of the mounting rod and the antenna, thereby preventing the antenna from being blown off the mounting rod or breaking the mounting rod by strong winds.

When the driving motor 8 is powered off, the first spring will push the slider 19 and the plug block 20 to move due to the restoration of its own elastic force and push one end of the plug block 20 to the outside of the fixing rod 2.

After the interior of the guide sleeve 16 is filled with gas, the overall strength of the guide sleeve 16 will be improved, thereby preventing the guide sleeve 16 from being flattened when wind force acts on the guide sleeve 16, thereby improving the use effect of the guide sleeve 16 and the miniaturized antenna for communication.

[0048] Working principle: By operating the control button 32, the driving motor 8 can be actively controlled to rotate forward and reverse. After the driving motor 8 is powered on, it can drive the driving shaft 12, the first bevel gear 14, the second bevel gear 15, the rotating shaft 13 and the rotating drum 10 to rotate. The rotating drum 10 is threadedly engaged with the mounting rod 3 and the guide sleeve 16 is limited. Therefore, the rotation of the rotating drum 10 can drive the mounting rod 3 and the antenna 4 to move up and down. The forward rotation of the driving motor 8 can drive the mounting rod 3, the antenna 4 and the guide sleeve 16 to move downward. The downward movement of the mounting rod 3 can install the antenna 4 on the mounting rod 3 or repair the antenna 4 on the mounting rod 3. The reverse rotation of the driving motor 8 can drive the mounting rod 3, the antenna 4 and the guide sleeve 16 to move downward. The sleeve 16 moves upward, and the mounting rod 3 moves upward, which can increase the installation height of the antenna 4 and improve the signal strength of the antenna 4. When the wind is strong, the wind will blow the mounting rod 3, the antenna 4 and the guide sleeve 16 and drive the guide sleeve 16 to squeeze the piezoelectric ceramic sheet 17 installed on the outer wall of the top end of the fixed rod 2. After the piezoelectric ceramic sheet 17 is squeezed, it will generate current and power the first solenoid valve. After the first solenoid valve is energized, it will close the circuit connected between the drive motor 8 and the battery 7 and start the drive motor 8 to rotate forward. The forward rotation of the drive motor 8 can drive the mounting rod 3, the antenna 4 and the guide sleeve 16 to move downward and lower the center of gravity of the mounting rod 3 and the antenna 4, thereby preventing the strong wind from moving the antenna 4 away from the mounting rod 2. The rod 3 is blown off or the mounting rod 3 is blown off, which not only improves the safety of the use of the miniaturized antenna for communication, but also reduces the cost of using the miniaturized antenna for communication; when the driving motor 8 is energized, the first electromagnet 23 will attract the slider 19 and the plug block 20 to shrink into the mounting groove 22, and the second electromagnet 28 will attract the annular mounting plate 24 and the limit rod 25 to move downward to the bottom end of the rotating drum 10, so that the rotating drum 10 can rotate freely and the mounting rod 3 and the guide sleeve 16 can move up and down freely. When the driving motor 8 is powered off, the first spring will push the slider 19 and the plug block 20 to move due to the restoration of its own elastic force and push one end of the plug block 20 to the outside of the fixed rod 2. At this time, one end of the plug block 20 is inserted into the corresponding socket 21 can fix the guide sleeve 16, the mounting rod 3 and the antenna 4 on the fixed rod 2 and prevent the guide sleeve 16, the mounting rod 3 and the antenna 4 from sliding up and down; when the driving motor 8 is powered off, the second spring will push the annular mounting plate 24 and the limiting rod 25 to move upward due to the restoration of its own elastic force and push the top of the limiting rod 25 to the upper side of the movable groove 27. At this time, the top of the limiting rod 25 is inserted into the bottom end of the rotating drum 10, so that the rotating drum 10, the mounting rod 3 and the antenna 4 can be fixedly connected to the fixed rod 2 and prevent the rotating drum 10, the mounting rod 3 and the antenna 4 from rotating, thereby improving the installation stability of the mounting rod 3, the antenna 4 and the miniaturized antenna for communication, thereby improving the use effect of the miniaturized antenna for communication.
