Description

Technical Field

[0001] This utility model relates to the field of flagpole technology, and in particular to a slewing ball head and a flagpole. Background Technology

[0002] A flagpole ball is a specially designed device installed at the top of a flagpole, its main function being to prevent the flag from getting tangled in the wind. This ball typically has the ability to rotate 360 ​​degrees with the wind, allowing it to rotate freely according to changes in wind direction, thus effectively preventing the flag from getting tangled with the flagpole. This design allows the flag to flutter freely in the wind, maintaining its flatness and appearance.

[0003] Traditional flagpole ball head designs rely primarily on wind power for their anti-tangling and reset functions. However, this design can be insufficient in weak winds. When the wind is not strong enough to propel the ball head to rotate, the flag may become tangled in the flagpole, preventing it from waving smoothly. Utility Model Content

[0004] The technical problem to be solved by this utility model is to solve at least one of the technical problems mentioned above.

[0005] The solution to the technical problem of this utility model is: a slewing ball head, including a slewing bearing, a ball head base, a power mechanism, a wire rope pulley system, and a ball head shell. The bottom surface of the outer ring of the slewing bearing is fixedly connected to the top of the flagpole body, the bottom surface of the ball head base is fixedly connected to the top surface of the inner ring of the slewing bearing, the wire rope pulley system is arranged on the ball head base, the power mechanism is internally engaged with the slewing bearing, and the slewing bearing drives the entire ball head to rotate.

[0006] The beneficial effects of this utility model are: when the flag is blown and rotated by the wind, the steel wire rope that fixes the flag will correspondingly drive the ball head to rotate, ensuring that the flag can be freely unfolded in the wind and avoiding its fluttering effect due to being wrapped around the flagpole; when the wind is weak, the flag may not be able to unfold on its own and may be wrapped around the flagpole. The motor can be started by controlling the button, and the motor drives the ball head to rotate, loosening the flag wrapped around the flagpole and ensuring that the flag can be unfolded again.

[0007] As a further improvement to the above technical solution, the power mechanism includes a gear reducer motor, a first gear, a second gear, a first platform, and a second platform. The first platform and the second platform are disposed in the internal space of the flagpole body. The gear reducer motor and the first gear are disposed on the first platform. The motor gear of the gear reducer motor meshes with the first gear. The second gear is disposed on the second platform. The first gear and the second gear rotate coaxially. The second gear meshes with the internal gear ring on the slewing bearing.

[0008] As a further improvement to the above technical solution, the aforementioned components are arranged within the internal space of the flagpole, achieving power transmission while ensuring the compactness of the overall structure and the high efficiency of its function. When the wind is weak and the flag cannot unfold on its own and becomes tangled around the flagpole, the motor is started by operating the control button. The motor's activation causes the ball joint to rotate, thereby untangling the flag from the flagpole and ensuring that the flag can be unfolded again.

[0009] As a further improvement to the above technical solution, the ball head base is provided with a first opening communicating with the internal space of the flagpole body and a second opening communicating with the external space. A copper sleeve is provided on the second platform. The copper sleeve and the flagpole body are cylindrical hollow structures. The internal space of the copper sleeve and the internal space of the flagpole body form a first channel. The wire rope enters the ball head through the second opening, passes through the wire rope pulley group, enters the copper sleeve, and returns to the ground through the first channel.

[0010] As a further improvement to the aforementioned technical solution, the wire rope enters the ball head through the second opening on the ball head base during use. Inside the ball head, the wire rope passes through a pulley system that changes its direction of movement. Guided by the pulley system, the wire rope passes through the first channel and eventually returns to the ground. This makes the movement of the wire rope smoother, avoiding direct exposure to the external environment and reducing the risk of damage caused by weather changes or external factors. Simultaneously, the presence of the copper sleeve ensures that the wire rope remains straight during movement, preventing bending or tangling, further enhancing the stability and reliability of the entire system.

[0011] As a further improvement to the above technical solution, a third opening is provided on the side wall of the ball head base, and bolts pass through the third opening to fix the ball head base and the ball head shell.

[0012] As a further improvement to the above technical solution, this improvement makes the connection between the ball head base and the ball head shell more secure, preventing loosening or detachment due to vibration or external force, thereby ensuring the stability and durability of the entire device during use.

[0013] As a further improvement to the above technical solution, the gear reduction motor is a forward and reverse reversible motor.

[0014] As a further improvement to the aforementioned technical solution, the reversible motor has the ability to flexibly change its rotation direction, effectively controlling the direction of flag wrapping according to actual needs. Regardless of wind direction changes, the motor ensures that the flag can always be smoothly unwrapped, maintaining a good display effect in various weather conditions.

[0015] As a further improvement to the above technical solution, a controller is provided at the bottom of the flagpole body, and the controller is electrically connected to the gear reduction motor.

[0016] As a further improvement to the above technical solution, by installing a controller at the bottom of the flagpole, operators can conveniently operate from the bottom of the flagpole while observing the real-time status of the flag. Secondly, the presence of the controller allows for more precise control of the rotation direction of the geared motor, thereby ensuring that the flag rotates in the intended manner.

[0017] As a further improvement to the above technical solution, the outer diameter of the ball head shell is larger than the outer diameter of the ball head base.

[0018] As a further improvement to the above technical solution, the larger outer diameter range provides a wider protective barrier for the ball joint assembly, making it more difficult for rainwater to penetrate the interior of the ball joint and avoiding corrosion problems caused by rainwater entering the interior of the ball joint.

[0019] As a further improvement to the above technical solution, the top of the ball head shell is set to an arc shape.

[0020] As a further improvement to the aforementioned technical solution, the rounded top of the electric flagpole can serve as a lightning protection mechanism. Since a smooth curved surface is less prone to current formation, it helps reduce the generation and accumulation of current. Therefore, designing the top of the flagpole as round can effectively reduce current formation and lower the safety hazards caused by lightning strikes.

[0021] A flagpole includes a flagpole body and a slewing ball head as described in any of the above technical solutions, wherein the slewing ball head is disposed on the flagpole body. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0028] A flagpole ball is a specially designed device installed at the top of a flagpole, its main function being to prevent the flag from getting tangled in the wind. This ball typically has the ability to rotate 360 ​​degrees with the wind, allowing it to rotate freely according to changes in wind direction, thus effectively preventing the flag from getting tangled with the flagpole. This design allows the flag to flutter freely in the wind, maintaining its flatness and appearance.

[0029] Traditional flagpole ball head designs rely primarily on wind power for their anti-tangling and reset functions. However, this design can be insufficient in weak winds. When the wind is not strong enough to propel the ball head to rotate, the flag may become tangled in the flagpole, preventing it from waving smoothly.

[0030] For this purpose, a rotating ball head, refer to Figures 1-2The system includes a slewing bearing 1, a ball head base 2, a power mechanism 3, a wire rope pulley assembly 4, and a ball head housing 5. The bottom surface of the outer ring of the slewing bearing 1 is fixedly connected to the top of the flagpole body 6, and the bottom surface of the ball head base 2 is fixedly connected to the top surface of the inner ring of the slewing bearing 1. The wire rope pulley assembly 4 is mounted on the ball head base 2, and the power mechanism 3 is internally engaged with the slewing bearing 1. The slewing bearing 1 drives the ball head to rotate as a whole.

[0031] When the flag is blown and rotated by the wind, the steel cable securing the flag will correspondingly rotate the ball head, ensuring that the flag can unfurl freely in the wind and avoid affecting its fluttering effect by getting tangled on the flagpole body 6. When the wind is weak, the flag may not be able to unfurl on its own and may get tangled on the flagpole body 6. The motor can be started by controlling the button, and the motor will rotate the ball head to loosen the flag tangled on the flagpole body 6, ensuring that the flag can be unfurled again.

[0032] Traditional designs rely on wind power for anti-tangling and repositioning functions, which may be ineffective in low wind conditions. Therefore, in one embodiment, the power mechanism 3 includes a geared motor 10, a first gear 11, a second gear 12, a first platform 13, and a second platform 14. The first platform 13 and the second platform 14 are located within the internal space of the flagpole body 6. The geared motor 10 and the first gear 11 are mounted on the first platform 13. The motor gear of the geared motor 10 meshes with the first gear 11. The second gear 12 is mounted on the second platform 14. The first gear 11 and the second gear 12 rotate coaxially, and the second gear 12 meshes with the internal gear ring on the slewing bearing 1. These components are arranged within the internal space of the flagpole body 6, achieving power transmission while ensuring a compact overall structure and high functional efficiency. When the wind is weak and the flag cannot unfold on its own and becomes tangled on the flagpole body 6, the motor is started by operating a control button. The motor's start causes the ball joint to rotate, thereby untangling the flag and ensuring it can unfold again.

[0033] Steel wire ropes exposed to the external environment are susceptible to shortened lifespan due to weather changes or other external factors. Therefore, in one embodiment, the ball head base 2 has a first opening 7 connecting to the internal space of the flagpole body 6 and a second opening 8 connecting to the external space. A copper sleeve 9 is provided on the second platform 14. The copper sleeve 9 and the flagpole body 6 are cylindrical hollow structures. The internal space of the copper sleeve 9 and the internal space of the flagpole body 6 form a first channel. The steel wire rope enters the ball head through the second opening 8, passes through the steel wire rope pulley system 4, enters the copper sleeve 9, and returns to the ground through the first channel. During use, the steel wire rope enters the ball head through the second opening 8 on the ball head base 2. Inside the ball head, the steel wire rope passes through a pulley system that can change the direction of movement. Guided by the pulley system, the steel wire rope passes through the first channel and finally returns to the ground. This makes the movement of the steel wire rope smoother, avoids direct exposure to the external environment, and thus reduces the risk of damage caused by weather changes or other external factors. Meanwhile, the presence of the copper sleeve 9 ensures that the wire rope remains straight during movement, avoiding the possibility of bending or tangling, and further improving the stability and reliability of the entire system.

[0034] When the slewing ball joint is installed in the air, it may become loose due to wind force. Therefore, in one embodiment, a third opening 15 is provided on the side wall of the ball joint base 2, and bolts pass through the third opening 15 to fix the ball joint base 2 and the ball joint housing 5. With this improvement, the connection between the ball joint base 2 and the ball joint housing 5 is more secure, preventing loosening or detachment due to vibration or external forces, thereby ensuring the stability and durability of the entire device during use.

[0035] Wind direction is variable and unpredictable, so flags may get tangled in various directions on the flagpole. Therefore, in one embodiment, the geared motor 10 is a reversible motor. A reversible motor has the ability to flexibly change its rotation direction, effectively controlling the direction of flag tangling according to actual needs. Regardless of wind direction changes, the motor ensures that the flag can always be easily untangled, maintaining a good display effect in various weather conditions.

[0036] For ease of operation and safety, in one embodiment, a controller is provided at the bottom of the flagpole 6, and the controller is electrically connected to the gear reduction motor 10. By providing a controller at the bottom of the flagpole, the operator can conveniently operate from the bottom of the flagpole while observing the real-time status of the flag. Furthermore, the presence of the controller allows for more precise control of the rotation direction of the gear reduction motor 10, thereby ensuring that the flag rotates in the intended manner.

[0037] Rust not only affects the service life of the ball joint but can also lead to equipment malfunctions, thereby affecting the stable operation of the entire system. Therefore, in one embodiment, the outer diameter of the ball joint housing 5 is larger than the outer diameter of the ball joint base 2. The larger outer diameter range provides a wider protective barrier for the ball joint assembly, making it more difficult for rainwater to penetrate the interior of the ball joint and avoiding rust problems caused by rainwater entering the interior of the ball joint.

[0038] Considering the need to avoid lightning strikes during flagpole use, it is crucial to minimize the formation of a path between the flagpole and the sky, thus preventing the generation of electric current. Therefore, in one embodiment, the top of the ball-head casing 5 is designed with an arc shape. The arc-shaped top of the electric flagpole can serve as a lightning protection mechanism. Since smooth curved surfaces are less prone to current formation, this helps reduce the generation and accumulation of current. Therefore, designing the top of the flagpole as circular effectively reduces current formation and lowers the safety hazards caused by lightning strikes.

[0039] A flagpole includes a flagpole body and a slewing ball head as described in any of the above technical solutions, wherein the slewing ball head is disposed on the flagpole body.

[0040] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
