Specific embodiment

Specific embodiment of the present utility model is given below, for making further details of solution to utility model content It releases.Therefore it does not limit the scope of the patent of the utility model, made by using the description of the utility model and the drawings Equivalent structure transformation, being applied directly or indirectly in other relevant technical fields, similarly includes in the special of the utility model In sharp protection scope.

Embodiment 1, referring to Fig.1: a kind of antiwind rotation flagpole, including base section 1, rotary shaft 2, rotation flagpole 3, institute It states rotary shaft 2 to be rotatably connected by bearing 4 with base section 1, the rotation flagpole 3 is rotatably installed in rotation by built-in bearing 5 In shaft 2, rainhat 6 is equipped at the top of the rotary shaft 2；

The rotation flagpole 3 is rotatably installed in rotary shaft 2 by built-in bearing 5, and the built-in bearing 5 is 2, respectively Positioned at the both ends of the rotation flagpole 3；

The rotary shaft 2 is rotatably connected by bearing 4 with base section 1, and the bearing 4 is 2, is located at the bottom The both ends of seat section 1；

3 lower part of rotation flagpole is installed by the fixing clasp 7 of fixed flag；

The rainhat 6 at 2 top of rotary shaft is fixedly connected with rotary shaft 2, and the lower end of the rainhat 6 is equipped with and prevents The prismatic 8 that flag falls off；

The rainhat 6 at 2 top of rotary shaft is fixedly connected with rotary shaft 2, and the rainhat 6 is umbrella, is equipped with above Ornament；

The embodiments of the present invention 1 are rotatably connected by bearing 4 with base section 1 by using the rotary shaft 2, institute The structure that rotation flagpole 3 is rotatably installed in rotary shaft 2 by built-in bearing 5 is stated, can slow down significantly or eliminate wind and blow flag When flag, rotation flagpole 3 or rotary shaft 2 extend bearing service life, especially rotation flagpole 3 and rotation to the surge of bearing The built-in bearing 5 that shaft 2 connects, since the torque that wind blows the point of application to the built-in bearing of flag is short, thus to built-in bearing Impact force it is small, as long as in addition, rotary shaft 2 does not occur stuck to prevent with rotary shaft 2 with base section 1 or rotation flagpole 3 simultaneously Only flag face wrapping phenomena greatly reduces the probability of flag face winding.

Embodiment 2, referring to Fig.1, Fig. 2: as advanced optimizing for embodiment 1, close to base section 1 in the rotary shaft 2 Upper-end part of driving has installed shield 9, and the shield 9 is in up-small and down-big taper, this structure can protect the bearing in base section 1 4, it prevents rain or lime-ash from falling on bearing, damages bearing.

Embodiment 3, referring to Fig.1, Fig. 2, Fig. 3: as advanced optimizing for embodiment 2, the rotation flagpole 3 is hollow Pipe, the corresponding position of the suspension flag of the rotation flagpole 3 are coaxially sheathed with built-in pipe 31,31 both ends of built-in pipe and rotation Turn the sealed connection of flagpole 3, ventilation gap 32, the built-in pipe are equipped between 31 outer wall of built-in pipe and 3 inner wall of rotation flagpole 31 internal diameters are greater than the rotation shaft diameter, and can rotate freely around rotary shaft 2, and the rotation flagpole 3 is located at suspension flag position Gap uniformly opens up multiple ventilation holes 33 from bottom to top on the side wall of side, and 33 diameter of ventilation hole is not more than 2mm, the rotation Turn the other side corresponding with suspension flag position on flagpole 3 and be equipped with strip air inlet 34,31 internal diameter of built-in pipe is greater than institute Rotary shaft 2 diameter at least 2mm is stated, this structure can further prevent flag face to bend, wrapping phenomena, and wind is from strip air inlet 34 It is blown into through 32 self-ventilation mouth of the ventilation gap blowout between 31 outer wall of built-in pipe and 3 inner wall of rotation flagpole, self-ventilation mouth is blown Wind out can reduce the bending of flag face, be further reduced the chance of flag face winding to flag face.
