Abstract

The utility model relates to a novel flagpole which utilizes the compressed air to blow the flag from the inside of a flagpole and cause the flag to flaunt under the conditions that the natural wind does not exist or the wind force is not big. The flagpole is composed of a fixed flagpole and a moveable flagpole. The lower end of the fixed flagpole is connected with an intake tube, and the moveable flagpole is composed of an outer tube whose lateral face is provided with a plurality of air outlet holes and an inner tube which is supported on two radial-thrust ball bearings. A pulley is arranged on the top of the outer tube of the moveable flagpole. The utility model overcomes the defects that the flag can sag and can not flaunt without wind as well as the flag can be affected when the flag is flaunting with the change of the wind direction, so the utility model is a comparative ideal novel flagpole.

Description

Flagpole

The utility model relates to a kind of novel flagpole, utilizes compressed air to blow out in the flagpole so that flag can wave when the little situation of no natural wind or natural wind.

Existing flagpole, after flag rises, the field that can rack when wind is arranged, when calm or wind then static sagging when very little, give free rein to, greatly influence the result of use of flag, and during change of the wind, because flagpole can not rotate with the wind, and flag is rolled, and influences attractive in appearance.

The purpose of this utility model be to provide a kind of can be from flagpole blow out air, the novel flagpole that the flagpole box haul is changed is so that the flag that is suspended on the flagpole at any time can both wave.

The purpose of this utility model is achieved in that flagpole is divided into movable flagpole part and fixing flagpole part, pulley at the top of movable flagpole device lifting flag, and on this activity flagpole, open some ventholes, fixedly the lower end of flagpole connects an air inlet pipe, compressed air enters flagpole by air inlet pipe, venthole by movable flagpole blows to flag, so that flag hour can wave at no natural wind or wind-force, movable flagpole lower end is bearing on the interior angular contact ball bearing of fixing flagpole, when change of the wind, flagpole can rotate thereupon, adjusts to the position that adapts to wind direction.

Below in conjunction with embodiment and accompanying drawing thereof technology contents of the present utility model is described in detail.

Fig. 1 is the profile schematic diagram of the novel flagpole of the utility model embodiment.

Fig. 2 is the sectional view of movable flagpole in the novel flagpole of Fig. 1.

Fig. 3 is that the A of Fig. 2 is to sectional view.

Fig. 4 is that the B of Fig. 2 is to sectional view.

Fig. 5 is the enlarged drawing of Fig. 2 I portion.

By figure, this novel flagpole comprises movable flagpole (1) and fixing flagpole (2,3), fixedly the flagpole lower end connects air inlet pipe (4), outside compressed air enters fixedly flagpole by air inlet pipe (4), be sent to movable flagpole again, movable flagpole is made up of outer tube (12) and interior pipe (13), and two pipes can be connected by flange (14), interior pipe (13) is bearing on two angular contact ball bearings (16,19), and two ball bearing installation sites are reverse.An oil sealing is adorned in ball bearing (19) below, and oil sealing can adopt labyrinth oil seal, and is fastening with nut (21).(22) are the inner ring of oil sealing among the figure, and (23) are the outer ring of oil sealing.The interior pipe of movable flagpole penetrates bearing (16), and bearing (16) is by pipe (17,18) supporting, and among the figure, (15) are elasticity retaining figure.The pulley (7) of lifting flag is equipped with at outer tube (12) top of movable flagpole, pulley (7) can be placed in the spherical shell of being made up of episphere (9) and lower semisphere (8), to increase aesthetic feeling, preferably be provided with iron strapping (10) above the pulley, iron strapping (10) is welded in the upper hemispherical shell (9), after installing halyard (11) on the pulley, cover lower semisphere.The side of the outer tube (12) of movable flagpole has some ventholes (24) on the position of flag, compressed air blows to flag by venthole, and flag can be waved under the natural wind state.Flag is preferably tied up on pole (5), for the non iron pole, then require respectively to adorn a steel bushing (6,30) at the two ends of pole (5), on the relevant position of the outer tube (12) of movable flagpole, install permanent magnet (20,29), horse tellurium shape permanent magnet for example, so that hold flag pole (5), flag can be rotated with movable flagpole.(25), (28) are respectively magnetic receiver among the figure, and (27) are the seat handle.Fixedly flagpole can be divided into some joints, is convenient to install, and embodiment is fixedly flagpoles (2,3) of two joints.Last half-section fixedly flagpole and following half-section fixedly flagpole be connected with garden taper pin (20).During use, air inlet pipe (4) is embedded in underground with fixing flagpole lower end, the blowing air compressor room.When calm or wind-force hour, start air compressor, compressed air, is blown out the flag of kicking up through the flagpole passage by air inlet pipe by the upper end air inlet.Some air inlets are arranged in permanent magnet center line both sides among the embodiment, blow to flag from both sides.

In sum, because the utility model adopts technique scheme, make that flagpole can blow out air, and box haul changes and adjustment flagpole position, thereby make flagpole at any time be able to freely wave, overcome existing flagpole when calm flag sagging, or wind direction is when changing, the flag affected defective of waving, thereby this flagpole is a kind of more satisfactory novel flagpole.
