Retractable flag post

Abstract

The invention provides a retractable flag post comprising a flag post base 1, tapered flag posts 2-4, pin penetrating screws 5 and a fixed pulley 6, wherein the hollow tapered flag posts 2-4 are small in top and big in bottom; the bottom of one tapered flag post is embedded into the top end of another tapered flag post by about 5-10cm and the pin penetrating screw 5 is applied to penetrating through a hole 7 formed in the overlapped parts of the two flag posts; the connection overlap parts between the tapered flag post 2 and the tapered flag post 3 are matched; and with the overlapped parts between the two adjacent tapered flag posts, the connection parts are in close fit with each other without shaking after the pin penetrating screws 5 are applied. The retractable flag post is the same as the existing marked-sold complete flag post in effect; if the flag lifting rope is broken, people just need to find a ladder to put down the flag post one section by one section, so that the flag lifting rope can be directly replaced, and then the people lift the flag posts to be at the original position one section by one section, and then the flag posts can be used again; and therefore, the retractable flag post is simpler than the existing complete flag post which needs three to five people to replace the flag rope.

Description

technical field [0001] The invention relates to a retractable flag raising pole, which can be used in schools, units and other places. Background technique [0002] At present, the flagpoles sold on the market are all just a pole about 6-8 meters long. The fixed pulley is installed on the top of the flagpole. The flag rope passes through the fixed pulley, and the flag rope is pulled up on the ground to raise the flag On the top of the flagpole, however, in our daily flag-raising activities, due to the sun and rain, the flag-raising rope tends to age and break. In this way, we need to replace the flag-raising rope, but because the flag-raising pole is 6-8 meters high, if we want to put It is not easy to pass the new flag rope through the fixed pulley, or people climb up to wear it, which is a very dangerous thing, and they do not usually do this. Either put the flag-raising pole down on the ground and put on the flag-raising rope and then erect it. These methods require thre...

[0002] At present, the flagpoles sold on the market are all just a pole about 6-8 meters long. The fixed pulley is installed on the top of the flagpole. The flag rope passes through the fixed pulley, and the flag rope is pulled up on the ground to raise the flag On the top of the flagpole, however, in our daily flag-raising activities, due to the sun and rain, the flag-raising rope tends to age and break. In this way, we need to replace the flag-raising rope, but because the flag-raising pole is 6-8 meters high, if we want to put It is not easy to pass the new flag rope through the fixed pulley, or people climb up to wear it, which is a very dangerous thing, and they do not usually do this

Either put the flagpole down on the ground and put on the flag rope before erecting it. These methods require three or five people, which is very troublesome and troublesome, and it is impossible for one person to complete it.
