Abstract

Disclosed is an easy flag-raising flagpole for middle schools and primary schools, which overcomes the problem that a flag rope of a flag raising device is easily damaged or lost. The easy flag-raising flagpole is characterized in that the top part of the easy flag-raising flagpole is provided with a bearing the upper cover of whose inner sleeve is provided with an upper pulley wheel, and the lower part of the easy flag-raising flagpole is provided with a hole which is provided with a lower pulley wheel. The lower pulley wheel is welded with a lifting box which is provided with a reel drum for collecting and releasing the flag rope wherein, and the flag rope passes through the inner part of the easy flag-raising flagpole. The utility model has the advantage that the service life of the flag rope is extended, the lost of the flag rope stolen by some person is prevented, the upper pulley wheel rotates with the wind, and the winding of a flag round a flag pole is avoided.

Description

Easy flag-raising flagpole

The simple and easy flagraising flagpole that the utility model is in a kind of being suitable for, the primary school uses.

Existing flagraising device mainly contains two kinds, and a kind of is hand, and another kind is an electrodynamic type.Manually the flagraising device is made up of flagpole, the flagraising halyard that is fixed on the pulley of truck and passes pulley, this flagraising device is because halyard passes the pulley of truck, so, the time spent can not take off, wind and weather at one's discretion damages very soon, loses but also cut by the people robber easily, in case damage or lose, it is very inconvenient again more to renew halyard; In addition, because pulley is fixed on a side of truck, thereby can not rotate with the wind, when wind direction changes, flag is wound on the flagpole.Electronic living Manchu attire is put mainly by the pulley of flagpole, truck, the flagraising halyard and the Motorized lift device that pass pulley and is formed.Electronic flagraising device is because its structure more complicated, thereby cost is higher, also needs the special messenger to nurse at ordinary times, in being not suitable for, the primary school uses.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, solves halyard and damages soon, is stolen by the people easily and cuts the problem of losing, and provides a kind of and does not twine, cost is low, be fit to the simple and easy flagraising flagpole that middle and primary schools use.

The utility model is to realize like this, it has a flagpole made from steel pipe, two upper and lower sliding sleeves that can slide thereon are installed on flagpole, one side of said upper and lower sliding sleeve is processed with through hole, and the fixedly bar of flag is installed therein, the upper end of bar is equipped with the nut of restricting admittedly, at the top of flagpole bearing is installed, and covers on the bearing inner sleeve top sheave is installed; Have a hole in the bottom of flagpole, a lower sheave is installed in the hole; At elevator chamber of lower sheave place welding, the reel of a folding and unfolding halyard is installed in the elevator chamber, the center of reel two end axles has square hole, be fixed on halyard on the solid rope nut and walk around the top sheave of truck, pass through bearing inner sleeve then, and pass from flagpole inside, walk around the lower sheave of flagpole bottom again, be fixed on the reel at last.During use, earlier flag is fixed on the bar, the crank that will have square toes then inserts in the square hole of reel, and the rotation crank can rise flag.

Advantage of the present utility model is that halyard passes from flagpole inside, has avoided wind and weather, thereby has prolonged the application life of halyard, can prevent also that simultaneously halyard from being cut by the people robber; Because the pulley of truck is fixed on the bearing inner sleeve and covers, so pulley can rotate with bearing inner sleeve, can adapt to different wind directions, has avoided flag to be wrapped on the flagpole.
