Easily-detached type protective net

Abstract

The invention relates to a protective net used for building windows. The easily-detached type protective net is characterized by comprising a frame, a steel wire rope, an upper metal bar, hanging columns and a lower metal bar. The right end of the upper metal bar penetrates through an upper metal bar hole and a right upper metal bar hole in sequence. The right end of the lower metal bar penetrates through a left lower metal bar hole and a right lower metal bar hole correspondingly. The multiple hanging columns are arranged on the upper metal bar in the left-right direction. The other multiple hanging columns are arranged in the lower metal bar in the left-right direction. The left end of the steel wire rope is fixed to the left end of the lower metal bar. The right end of the steel wire rope penetrates through the two leftmost adjacent hanging columns on the upper metal bar upward, then penetrates through the two leftmost adjacent hanging columns on the lower metal bar downward, penetrates through the another adjacent hanging columns on the upper metal bar upward again and then penetrates through another two leftmost adjacent hanging columns on the lower metal bar downward, in this way, penetrating is conducted in a winding mode from left to right, and finally the right end of the steel wire rope is tied in an annular shape and put around one hanging column on the rightmost side of the upper metal bar. The protective net is simple in structure, easy to detach and high in detaching speed and further has a life-saving function.

Description

technical field [0001] The invention relates to a protective net for building windows. Background technique [0002] The main body of the existing protective net is formed after several vertical bars and horizontal bars are vertically connected to each other. The disadvantages are: complex structure, difficult to disassemble, and no life-saving function. [0003] When a house catches fire, because the protective net outside the window is welded and fixed (vertical and horizontal bars are welded and fixed), it is not easy to disassemble, and when the passageway at the door is sealed by fire, people have nowhere to escape, resulting in being burned to death. There are reports from time to time . And when there is no protective net outside the window, there are reports from time to time that the people in the house jumped directly from the window and fell to their deaths as a result. [0004] How to provide a protective net that can play a protective role, is easy to dismantl...

[0003] When a house catches fire, because the protective net outside the window is welded and fixed (vertical and horizontal bars are welded and fixed), it is not easy to disassemble, and when the doorway is sealed by fire, people have nowhere to escape, resulting in being burned to death. There are reports from time to time

And when there is no protective net outside the window, people in the house jump directly from the window, and they fall to their deaths. It is also reported from time to time.
