Abstract

The utility model relates to a novel flag post which comprises an inner post and a rotating device positioned on the inner post, wherein the rotating device comprises an outer post sheathed outside the inner post and fixing sleeves positioned at the upper and the lower ends of the outer post. The upper and the lower parts of the inner post are respectively provided with an upper and a lower spacing sleeves which are tightly matched with the upper and the lower parts of the inner post, and rolling balls used for the outer post to rotate relatively to the inner post are arranged in inner cavity formed between each fixing sleeve and the corresponding spacing sleeve. By adopting the structure, a flag only needs to be fixed on the outer post. Thereby, the defect that the flag winds the flag post is overcome and the wind force which is borne by the flag post is reduced. The whole flag post has the advantages of simple structure and convenient and quick installation. Besides, the outer post can be designed with an outer diameter identical to the appearance of other components so as to beautify the integral effect of the assembled flag post; the flag post can be conveniently packed and transported by adopting an auxiliary post, and the upper and lower sections of the flag post can also be conveniently assembled and disassembled. Tight loops, screw rods and screws additionally designed can easily replace the flag. The utility model has novel structure, and is worth popularizing and applying in every occasion.

Description

A kind of novel flagpole

Technical field

The utility model relates to a kind of flagpole, especially refer to a kind of rotatable, can prevent the novel flagpole that flag twines.

Background technology

Common flagpole is a upright pipe bar, and flag carries out lifting with the pulley of rope and flagpole upper and lower end usually to be fixed, thereby reaches the purpose that hangs flag.But in use find, there is a defective that can't overcome, promptly when flag waves with the wind, can often occur that flag is wrapped on the flagpole and the phenomenon that can not show fully.Obviously, such flagpole has also influenced the activity meaning and the atmosphere of grand occasion in some when can't embody flag and show implication in red-letter day.For this reason, people design a kind of rotatable flagpole, and flagpole is provided with whirligig usually, and this device can be made up of a jacking sleeve, ball bearing and swing roller; Also can adopt and on flagpole, install tumbler, kinematic link and following steering mechanism, wherein steering mechanism comprise master gear again, from gear, deflecting roller and bearing, structure although it is so can overcome above-mentioned defective to a certain extent, but because its complex structure, thereby cost of production height, assembling inconvenience, and rotate also underaction.This shows that existing flagpole has unsatisfactory part in the use, still need await further raising.

Summary of the invention

Technical problem to be solved in the utility model is the present situation at prior art, provide a kind of simple in structure, rotate flexibly and the low novel flagpole of cost.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: bar and the whirligig that is positioned on the bar in this novel flagpole comprises, it is characterized in that: described whirligig comprises the fixed cover that is enclosed within the outer bar outside the interior bar and is positioned at outer bar upper and lower end, the position up and down of bar then is respectively equipped with and its upper and lower spacing cover of close-fitting mutually in described, is mounted with in the inner chamber that forms between each fixed cover and the above-mentioned corresponding stop collar for the ball of outer bar with respect to interior bar rotation.

The external diameter that is equal to formation between above-mentioned outer bar, fixed cover and the stop collar after the assembling is good, makes that whole flagpole is more both artistic and practical.

As further improvement of the utility model, below interior bar, can be provided with and is connected the hollow auxiliary rod that is the buckle-type connection between the position with lower limit cover.This buckle-type connects can adopt following mode: the connecting portion at stop collar is provided with " type lead-in groove, and be provided with associated projection on the auxiliary rod inwall.

As another kind of improvement the of the present utility model, described outer bar is provided with upper and lower tight loop, radially is bolted with the screw rod of band nut on each tight loop, when flag is installed, can reach purpose fast, easily like this.

Compared with prior art, advantage of the present utility model is: because outer bar can rotate with respect to interior bar neatly, therefore only need flag is fixed on the outer bar, can overcome the defective that flag is wound in flagpole, also reduced simultaneously the wind-engaging strength of flagpole, and whole flagpole is simple in structure, and is easy for installation, quick.Moreover, outer bar is designed to and the identical external diameter of whole flagpole profile, make that the whole structure of flagpole is more practical and attractive.And flagpole then both can be packed, be transported to the auxiliary rod that adopts buckle-type to connect easily, is convenient to the mounting or dismounting of upper and lower section flagpole again, and also can satisfies the use of different occasions.She Ji tight loop, screw rod and nut can be changed flag like a cork in addition.Therefore the utility model novel structure is practical, is worth applying in each occasion.

Description of drawings

Fig. 1 is the sectional view of the utility model embodiment;

Fig. 2 is equipped with profile schematic diagram behind the flag for the utility model embodiment;

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Illustrated in figures 1 and 2, this flagpole comprises interior bar 1, is positioned at whirligig and auxiliary rod 9 on the bar, wherein whirligig comprise again be placed in outer bar 2 outside the bar 1 and the tight inserting fixed cover 3 of bar upper and lower end outside, the place, upper and lower position of interior bar then is respectively equipped with and its upper limit cover 4a and the lower limit cover 4b of close-fitting mutually, each fixed cover 3 all is step-like with above-mentioned corresponding stop collar, after the assembling, make and form annular cavity between the two, and in this inner chamber, be mounted with a plurality of balls 5, with the purpose that realizes that outer bar 2 rotates flexibly with respect to interior bar 1.

In order to satisfy the use of different occasions, above-mentioned auxiliary rod 9 is designed to a hollow tube, its with the connecting portion of lower limit cover 4b between be buckle-type and be connected, promptly the connecting portion appearance of overlapping 4b in lower limit is provided with " type lead-in groove 4b-1, and be provided with associated protruding 91 on auxiliary rod 9 inwalls.During assembling, only need that the projection on the auxiliary rod 9 91 is inserted into lower limit along lead-in groove and put, rotate an angle again, can apace auxiliary rod 9 and lower limit cover 4b, interior bar 1 etc. be fused.

Consider the overall aesthetics of flagpole, here, outside inserting in when fixedly being locked up and down behind the upper and lower port of bar, the external diameter of outer bar be exposed to the external diameter of the fixed cover up and down outside the outer bar and up and down stop collar external diameter, auxiliary rod external diameter homogeneous phase be equal to, the flagpole integral body after make assembling is completely had a style of one's own.

Simultaneously outside above-mentioned, also be with upper and lower tight loop 6 on the bar 2, radially be bolted with the screw rod 7 of band nut 8 on each tight loop.Correspondingly, on flag 10, be provided with installing hole.During use, as long as flag 10 is hung on the screw rod 7, and tighten nut 8 on the respective threaded rod, can reach the purpose of fastening flag by installing hole.
