Technical Field

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

[0002] A flagpole is a structure specially designed to hang flags, and it is widely used in many occasions.

[0003] However, flags flying on flagpoles may become entangled around the pole in strong winds, affecting their display and diminishing their symbolic meaning. Depending on the environment, flagpoles may need to be placed at an angle; typically, they are inserted diagonally into their bases. However, a non-adjustable flagpole makes changing flags very inconvenient. This design limitation makes maintenance and flag replacement complex and time-consuming, impacting the flagpole's efficiency and display effectiveness.

[0004] In windy conditions, flagpoles are prone to breaking, tipping, or swaying, posing safety hazards. In addition, existing flagpoles are connected in a fixed manner without shock absorption, which can easily lead to damage. Utility Model Content

[0005] The technical problem to be solved by this utility model is to solve at least one of the technical problems mentioned above.

[0006] The solution to the technical problem of this utility model is: a slanted flagpole, comprising a fixed base, a insertion tube, a shock-absorbing mechanism, a pole body, a bearing, a flag hanging tube, and a ball head.

In addition, all the connection / connection relations mentioned in the paper do not mean that the components are directly connected, but can be composed of a better connection structure by adding or reducing the connection auxiliary parts according to the specific implementation situation. The various technical features in the utility model can be interactively combined without mutual contradiction and conflict.

[0029] The flagpole is a structure specially designed for hanging flags, which is widely used in many occasions.

[0030] However, the flag flying on the flagpole may be wrapped around the pole body 4 in strong wind, affecting the display effect of the flag and weakening its symbolic meaning. According to the needs of the use environment, the flagpole needs to be placed obliquely, and in general, the flagpole is inserted obliquely on the flagpole seat, but the flagpole that cannot be adjusted is very inconvenient when replacing the flag. The limitation of this design makes it complicated and time-consuming to maintain and replace the flag, affecting the use efficiency and display effect of the flagpole.

[0031] In a strong wind environment, it is easy to break, fall down, and swing with a large amplitude, thereby causing safety hazards. Meanwhile, the existing flagpoles are connected in a fixed manner without damping effect, which is easy to cause damage to the flagpole.

[0032] Therefore, an obliquely inserted flagpole, referring to Figures 1-4 , comprising a fixed seat 1, a plug-in pipe 2, a damping mechanism 3, a pole body 4, a bearing 5, a flag hanging pipe 6 and a ball head 7, the bottom of the pole body 4 is inserted into the plug-in pipe 2 and locked by bolts, the damping mechanism 3 is arranged on the plug-in pipe 2, the plug-in pipe 2 is fixedly arranged on the fixed seat 1, the flag hanging pipe 6 is rotatably connected with the top of the pole body 4 through the bearing 5, the flag hanging pipe 6 is sleeved on the pole body 4, the outer ring of the bearing 5 is fixedly connected with the inner wall of the flag hanging pipe 6, the inner ring of the bearing 5 is fixedly connected with the outer wall of the pole body 4, and the bottom of the ball head 7 is threadedly connected with the top of the pole body 4.

[0033] The outer pole of the flagpole can rotate with the change of wind direction, so that the flag is not easy to wrap around the flagpole in a strong wind environment and the problems of flag tearing or flagpole damage caused by wind force are avoided. Meanwhile, the damping mechanism 3 further improves the wind resistance of the flagpole and effectively absorbs and buffers the impact of wind force on the flagpole.

[0034] The flagpole will be impacted by the wind, which may cause vibration and noise. Thus, in an embodiment, the top surface of the insertion tube 2 is provided with a first flange plate 8, and a circle of side walls 9 is provided on the top surface of the first flange plate 8. The damping mechanism 3 is arranged in a circumferential arrangement on the side wall 9, and the damping mechanism 3 is composed of a damping block 10, a damping box 11, a spring 12 and a damping rod 13. The damping block 10 is fixedly connected to the damping box 11 on the outer wall, the damping rod 13 is inserted into the damping box 11, the spring 12 is fixedly connected to the inner end of the damping rod 13, the damping rod 13 is fixedly connected to the inner side of the side wall 9, and the other end of the spring 12 is fixedly connected to the outer wall of the damping block 10. The rod body 4 is inserted between the damping blocks 10. The damping mechanism 3 is composed of the damping block 10, the damping box 11, the spring 12 and the damping rod 13, so that when the wind force is transmitted to the insertion tube 2, the damping rod 13 absorbs and disperses the impact force through the elastic deformation of the spring 12. Through the design of the circumferential arrangement of the damping mechanism 3, the vibration energy is absorbed and dispersed in all directions, effectively reducing the noise and wear caused by vibration of the equipment.

[0035] In some cases, such as areas with strong winds or occasions that require special display effects, the upright flagpole may not be able to perfectly display the grace and dignity of the flag. Thus, in an embodiment, the insertion tube 2 and the fixed seat 1 form an acute angle. The inclined flagpole can ensure that the flag naturally droops under the action of gravity. This effectively solves the problem of flag curling and winding due to wind force, ensuring the neatness and beauty of the flag. On the other hand, the inclined flagpole can also enhance the display effect of the flag to some extent, so that the audience can clearly see the patterns and texts on the flag from a farther distance, thereby improving the efficiency and accuracy of information transmission.

[0036] The flagpole 6 will rotate under the action of wind and may be separated from the fixed tube 17.

The limiting of the inner snap spring 14 and the double outer snap spring 15 enhances the stability and safety of the entire structure; the bearing bracket reduces the friction resistance during rotation, ensures that the bearing 5 can rotate smoothly therein, and at the same time withstands various forces from the flag; the outer sleeve tube 16 is sleeved on the outer side of the lower part of the fixed tube 17, and the two are screwed together, which ensures the firmness of the connection and effectively prevents loosening caused by external force.

[0037] Rainwater may erode the damping mechanism 3. Thus, in an embodiment, the outer sleeve tube 16 is sleeved with a second flange plate 27 on the outer side of the lower part, and the first flange plate 8 and the second flange plate 27 are fixedly connected by nuts and screws. The fixed connection by nuts and screws enhances the stability of the connection, the closed space formed by the flange plate and the side wall 9 also effectively prevents rainwater erosion, in addition, it is also convenient for installation and maintenance, making the connection and disconnection more simple and fast.

[0038] In the environment of gale, the flagpole may be broken due to insufficient strength.

[0039] The ball head 7 of the flagpole may need to be replaced. Thus, in an embodiment, the cylindrical body 20 is provided with a threaded column 28 on the surface facing away from the fixing tube 17 for fixing with the ball head 7. The connection mode of the threaded column 28 combined with the ball head 7 can reduce the probability of loose connection and facilitate subsequent maintenance and replacement work.
