Abstract

The invention discloses a flag post capable of maintaining the spread state of a flag. An upper sleeve is arranged at the top end of the flag post. A radial pin is arranged on the upper sleeve. A radial pin body in the upper sleeve is connected with an upper edge opening of the flag post. The flag post is provided with a lower sleeve and a radial limiting pin connected with the upper edge opening of the lower sleeve. A connecting rod is fixed between the upper sleeve and one side of the lower sleeve. One end of a transverse rod is provided with two parallel insertion rods perpendicular to the transverse rod. The two insertion rods are connected with the upper sleeve in an insertion mode and are deeply inserted into the flag post. The radial pin body is located between the two insertion rods when the two insertion rods are connected with the upper sleeve in the insertion mode. The flag post can effectively solve the problem that the flag is wound on the flag post or the transverse rod under the action of wind power, and has the advantages of being simple in structure, reliable in flag winding preventing effect, convenient to use, suitable for various oblong and square flags.

Description

The flagpole that keeps flag deployed condition

Technical field

The invention belongs to flagpole, particularly a kind of flag spooling of can avoiding keeps the flagpole of flag deployed condition in flagpole.

Technical background

In windy season, flag is easy to spooling under wind-force effect to be affected it in flagpole and launches completely.

The application for a patent for invention < < flagpole > > of publication number CN1486480A discloses a kind of flag spooling of can avoiding in the technical scheme of flagpole, near cross bar of at right angle setting flagpole top, its mode is, at the top margin of flag, do one and embed lip, it can be inserted in a groove of determining along cross bar length direction, thereby prevent that flag is wrapped on flagpole, the deployed condition while keeping initial; Its cross bar is vertically mounted near the top of flagpole removably, is convenient to like this harvesting of flagpole; Its cross bar is foldably vertically mounted near the top of flagpole, is convenient to like this collection of flagpole; A baffle ring is enclosed within on flagpole, under the position of baffle ring, with a belt, the lower end of flag is tied up on flagpole, so just can prevent that belt from moving up, thereby flag is remained under the state launching completely.

There is following practical problem in above-mentioned < < flagpole > >, because flag one side that exists of cross bar can not adopt known flag side cover to be socketed on the traditional method of flagpole, and can only adopt belt to lie in the structure of flagpole, not only exist to use and owe defect easily, also exist simultaneously because of belt do not fasten make flag under wind-force effect spooling in the defect of cross bar.

Summary of the invention

The present invention is easy to spooling and in flagpole, affects its technical problem of launching completely and disclose a kind of flagpole that keeps flag deployed condition in order to overcome flag under wind-force effect.

The present invention takes following technical scheme for achieving the above object: a kind of flagpole that keeps flag deployed condition, comprise cross bar, feature is, described flagpole top is provided with sleeve pipe, upper sleeve pipe is provided with radially pin, radial peg rivet nut in upper sleeve pipe engages with flagpole upper edge hole, described flagpole is provided with setting of casing and is engaged in the radially position-limitting pin of setting of casing upper edge hole, between described upper sleeve pipe and a cased side, be fixed with connecting rod, described cross bar one end is provided with vertical with cross bar two parallel inserted links, two inserted links insert and engage and penetrate with flagpole with upper sleeve pipe, when two inserted links engage with upper sleeve pipe insertion, the radial peg rivet nut of upper sleeve pipe is between two inserted links.

The present invention can also take following technical measures:

The radially position-limitting pin that the radially pin of described upper sleeve pipe and flagpole are engaged in setting of casing upper edge hole is rivet, and the rivet two ends after installation are cup head.

The radially position-limitting pin that the radially pin of described upper sleeve pipe and flagpole are engaged in setting of casing upper edge hole is opening pin.

Beneficial effect of the present invention is with advantage: the sleeve pipe up and down that this flagpole is connected by connecting rod and flagpole rotational engagement, and by pin radially and radially position-limitting pin make distance between upper and lower sleeve pipe and with the location positioning of flagpole.Cross bar makes cross bar and the flagpole can be separated by two parallel inserted links and the socket connection mode of upper sleeve pipe, so this flagpole can use the flag of the prior art that side cover and top are overlapped is set respectively.Because the position-limitting pin body in upper sleeve pipe is positioned between the parallel inserted link of cross bar two, so the swing of cross bar can drive upper and lower sleeve pipe to rotate simultaneously.Can infer, by the flag that side overlaps and top cover is connected in this flagpole and cross bar, under wind-force effect, also can make cross bar swing, and then upper and lower sleeve pipe is rotated simultaneously, therefore this flagpole can effectively solve flag under wind-force effect spooling in the phenomenon of flagpole, due to flag side cover be socketed on flagpole can not occur yet flag under wind-force effect spooling in the phenomenon of cross bar.The outstanding advantages that the present invention has simple in structure, anti-flag spooling is reliable for effect, easy to use, be applicable to various rectangles, square flag.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing thereof, further illustrate the present invention.

Embodiment as shown in Figure 1,2,3, 4,flagpole 1 top is provided with sleeve pipe 2, and upper sleeve pipe 2 is provided with radiallypin 3, and the radial peg rivet nut in upper sleeve pipe 2 engages withflagpole 1 upperedge hole.Flagpole 1 is provided with setting ofcasing 5 and is engaged in the radially position-limittingpin 6 of setting of casing upper edge hole, between described upper sleeve pipe 2 and a side of setting ofcasing 5, is fixed with connectingrod 7, and the distance between upper sleeve pipe 2 and setting ofcasing 5 and flag are wide quite.

Cross bar 4 diagram right-hand members are provided with vertical withcross bar 4 two parallel inserted link 4-1, and two parallel inserted link 4-1 insert and engage and penetrate withflagpole 1 with upper sleeve pipe 2, upper sleeve pipe during insertion joint 2 its radiallypin 3 between two inserted link 4-1.

The radially position-limittingpin 6 that the radiallypin 3 of upper sleeve pipe 2 as shown in Figure 1,2,3, 4 andflagpole 1 are engaged in setting ofcasing 5 upper edge holes is rivets, and the rivet two ends after installation are cup head.Described radiallypin 3 and radially position-limittingpin 6 also can adopt opening pin.

As shown in Figure 5, theflag 8 supporting with flagpole of the present invention belongs to existing flag structure, and one side is provided with side cover 8-1, and the bottom of side cover is provided with opening, and the base angle end of opening is provided with tether 8-3.The upper side edge offlag 8 is provided with top rail cover 8-2, and top rail cover left end is sealing.Be socketed onflagpole 1 and connecting rod horizontal to be arranged withcorresponding cross bar 4 tail ends be the sealing of 4 left ends of cross bar shown in Fig. 1.

Using method below in conjunction with Fig. 1,5,6 these flagpoles of brief description: first the part side cover 8-1 offlag 8 is socketed on toflagpole 1, againcross bar 4 is penetrated to the top rail cover 8-2 of flag, pull subsequently side cover 8-1 downwards, when upper sleeve pipe 2 is taken advantage of a situation sleeve pipe 2 two inserted link 4-1 insertions ofcross bar 4 when side cover 8-1 exposes, finally at this connectingrod 7, fasten tether 8-3 with the joint portion of setting ofcasing 5 or the bead place, the end of setting ofcasing 5, tether can avoid flag under wind-force effect along emerging in large numbers and resemble on flagpole.
