Abstract

The utility model relates to a rotatable flagpole, which comprises a pole body that is rotatably arranged on a base. For the rotatable flagpole, as the pole body can rotate relatively to the base, a fluttering flag can drive the pole body to rotate relatively when the wind direction is changed or the wind power is suddenly increased, so that the flag can be prevented from being wound on the flagpole and can flutter in the wind highly all the time.

Description

Rotatable flagpole

Technical field

The utility model relates to a kind of roofbolt building, especially relates to a kind of rotatable flagpole.

Background technology

Common flagpole generally comprises the flagpole body of rod that is fixed in ground, be positioned at the fixed pulley of body of rod upper end and pass the rope of fixed pulley.In use, when flag is raised to the flagpole top, because the elasticity and the body of rod of rope self are fixed, during big or wind direction flip-flop, the flag that flutters is easy to be wound on the flagpole, influences appreciation effect at wind-force.

The utility model content

The technical problems to be solved in the utility model provides a kind of under the high wind environment, can prevent the flagpole that flag twines.

Rotatable flagpole of the present utility model comprises the body of rod, and the body of rod is rotatable to be installed on the pedestal.

Rotatable flagpole of the present utility model, wherein, described pedestal can be fixed in ground.

Rotatable flagpole of the present utility model, wherein, pedestal connects the inwall of the described body of rod by rolling bearing.

Rotatable flagpole of the present utility model, wherein, the end face of described pedestal is provided with rotatable steel ball, is fixed with the metal bearing plate on the inwall of the described body of rod, and the described body of rod is placed on the steel ball by described metal bearing plate.

Rotatable flagpole of the present utility model, wherein, the end face of described pedestal is provided with groove, and described steel ball is placed in the described groove, and the degree of depth of described groove is less than the diameter of described steel ball.

Rotatable flagpole of the present utility model, wherein, described pedestal is connected the inwall of the described body of rod by first rolling bearing and second rolling bearing.

Rotatable flagpole of the present utility model, wherein, be with first limit casing and second limit casing on the described pedestal, described first limit casing is between described first rolling bearing and described second rolling bearing, and described second limit casing is between the base of described second rolling bearing and described pedestal.

Rotatable flagpole of the present utility model wherein, is provided with taper between the inwall of described first rolling bearing, second rolling bearing and the described body of rod.

Rotatable flagpole of the present utility model, because the body of rod can rotate with respect to pedestal, no matter wind direction flip-flop or wind-force increase suddenly, the flag that flutters all can drive the body of rod and do corresponding rotation, make flag avoid being wrapped on the flagpole, flutter in the breeze all the time, high waving.

Rotatable flagpole of the present utility model, be fixed with the metal bearing plate on the inwall of the body of rod, the body of rod is placed on the steel ball on the pedestal end face by the metal bearing plate, and the metal bearing plate that is fixed in body of rod inwall can rotate on steel ball, and this design can make the rotation of the body of rod more flexible.

Rotatable flagpole of the present utility model is provided with taper between the inwall of first rolling bearing, second rolling bearing and the body of rod, utilizes taper to make the installation between the body of rod and the pedestal more convenient.Simultaneously, taper make first rolling bearing and second rolling bearing more firm remain in the permanent position.

Description of drawings

Fig. 1 is the structural representation of the rotatable flagpole of the utility model;

Fig. 2 is the A partial enlarged drawing of Fig. 1.

The specific embodiment

As shown in Figure 1 and Figure 2, the rotatable flagpole of the utility model comprises the cylindrical pedestal 9 that can be fixed in ground and rotatablely is installed in the body of rod 11 on the pedestal 9.

Pedestal 9 bottoms comprise base 2, have on the base 2 in order to the screw of fixed base frame 9 in ground.

The upper end of the body of rod 11 is equipped with top sheave 12, and the bottom of the body of rod 11 is equipped with lower sheave 13, and the wheel face of top sheave 12 and lower sheave 13 is on a vertical plane, and the slide down wheel is positioned at the same side of the body of rod 11.Rope 14 passes top sheave 12 and walks around lower sheave 13.

The bottom of the body of rod 11, the below of lower sheave 13, the circular metal bearing plate 15 of welding on the body of rod 11 inwalls, the inwall of the circumferential edges of metal bearing plate 15 and the body of rod 11 bottoms welds together.

Have circular groove 41 on the end face of the pedestal 9 of columned metal material, the center of circle of groove 41 is positioned on the axial line of pedestal 9, and the surface scribbles the steel ball 5 of lubrication oil and places wherein.The degree of depth of groove 41 is less than the diameter of steel ball 5.The body of rod 11 is placed on the steel ball 5 by metal bearing plate 15.

Be connected with second rolling bearing 7 by first rolling bearing 6 between the interior ancient piece of jade, round, flat and with a hole in its centre of pedestal 9 and the body of rod 11 bottoms.Be with on the pedestal 9 and be used to the first spacing limit casing 21 of first rolling bearing 6 and be used to the second spacing limit casing 22 of second rolling bearing 7.First limit casing 21 is between first rolling bearing 6 and second rolling bearing 7, and second limit casing 22 is between the base of second rolling bearing 7 and pedestal 9.

The upper end is little, and the big taper 3 in lower end is used for filling the space between rolling bearing 6,7 and the body of rod 11 inwalls, and makes rolling bearing 6,7 remain on the permanent position between rolling bearing 6,7 and the body of rod 11 inwalls.

Rotatable flagpole of the present utility model, because the body of rod 11 can rotate flexibly with respect to the pedestal 9 that is fixed in ground, therefore no matter wind direction flip-flop or wind-force increase suddenly, and the flag that flutters all can drive the body of rod 11 and do corresponding rotation, makes flag avoid being wrapped on the body of rod 11.

The above embodiment only is that preferred implementation of the present utility model is described; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
