Abstract

The utility model relates to a flag lifting device without a rope, and the inner part of a flagpole is provided with a pulley and movable magnets. A flag side is arranged on the outer magnet, and the pulley is rotated. The inner movable magnet and the outer movable magnet are driven by a steel rope to move up and down and complete flag lifting and falling operations. The utility model is suitable for various flag lifting occasions, and the rope can not be seen outside the flagpole, which causes the surrounding part of the flagpole to be neat and statedly. The utility model has simple structure and reasonable design, and is an ideal flag lifting device.

Description

No rope flagraising device

The utility model belongs to flagraising Design of device and manufacturing technology field.

All be to adopt rope to drive pulley holding the used flagraising device of large-scale celebration occasion at present, by the mode of artificial pulling flagraising, the perhaps mode of hoisting a flag by the motor drives rope pulley.But rope all is the outside at flagpole, swings with the wind and influences attractive in appearance, not ideal.

The purpose of this utility model provides a kind of no rope flagraising device, specifically is to have pulley and movable magnet in flagpole inside, and the flag face is contained on the flagpole external magnets, moves up and down a kind of flagraising device of finishing the lifting flag under steel cable drives.

Structure of the present utility model as shown in drawings; Main frame for movement is arranged within the flagpole.In the bottom of flagpole (9) driving pulley (7) is arranged, a movable rocking handle (8) is arranged on the pulley.One auxiliary pulley (6) is arranged at driving pulley top.Top sheave (1) and location pulley (2) are arranged on the top of flagpole, have steel cable (5) on the pulley.These pulleys are fixed on the flagpole.Have movable inner magnet (3) in flagpole, a circular hole is arranged in the middle of the inner magnet, steel cable (5) combines by inner magnet circular hole and top sheave and driving pulley.The two ends of steel cable are separately fixed at the inner magnet upper and lower.Outside corresponding inner magnet place at flagpole has outer magnet (4), and the outer magnet bottom is a curved surface, and combination is inhaled mutually with the inner outer magnet of flagpole curved surface in the bottom surface.Have several pearl grooves on the outer magnet bottom surface, free ball is housed in the groove, a little higher than outer magnet of ball bottom surface is so leave minim gap between bottom surface and the flagpole.One circular hole is arranged at outer magnet top, and a gap is arranged at the top in hole.The length of outer magnet equates that with the height of flag face outer magnet can be a whole piece, also can make some.One braking lock (10) is arranged in the bottom of flagpole.Inner magnet of the present utility model can be a permanent magnet, also can be electromagnet or metallic iron.Outer magnet can be metallic iron or permanent magnet.It is that the flag trousers are put a wooden or plastics system that this reality has novel using method, with outer magnet top circular hole same diameter pole, then the flag face is settled on the outer magnet circular hole gap, rotate the rocking handle on the driving pulley then, driving inner magnet by steel cable moves up, outer magnet is inhaled together across the flagpole shell mutually with inner magnet, moves up simultaneously.Finish the action of hoisting a flag.Pin driving pulley by the braking lock then, make the flag face static.There is a hole at the place at the corresponding driving pulley fixed axis in flagpole bottom, is used to put in movable rocking handle, wait to finish the lifting flag after, take off rocking handle.The action of this device lifting flag is available manually, also can be electronic.Electronic as need, install electric device and get final product.

The utility model is simple in structure, and is reasonable in design.The result has removed the rope that is exposed to the flagpole outside, makes flagpole seem neat and artistic on every side.Because the outer magnet bottom surface has roller ball, the flag face is racked take office where to flag face roll bar phenomenon does not take place.

Flagpole of the present utility model is magnesium steel pipe system not, requires inside and outside wall smooth, if can make whole conical better, otherwise then need be by the joint welding.Interior outer magnet can adopt corresponding permanent magnet, electromagnet or metallic iron.Remaining part such as steel cable, pulley can adopt general part or standard component.Its enforcement can be with reference to manual and accompanying drawing, and processing, assembling get final product.
