Abstract

The gas leak protection latch is an invention with a stopper that is used to block the gas passage of the gas cylinder valve head, with a small, round cable extending before the end of the hose with a wedge shaped like a convex shape on one side. Several are lined up to be used indirectly into the casing that has a bolt inside, through a circular hole on the other side, when inserted into the bolt until the strap is tightened as possible and cannot be pulled back as the wedge will be forced by the bolt. Inside, so that the residue and the bolts cannot be pulled out, all of which are in one piece.

Claims (1)

1. The gas emission protection bolts are always made of a single piece of plastic, with the appearance of a cylindrical-shaped plug on the other side of the block on the side of the block. Two small round strings that are slightly apart and slightly protruding and converge into a triangle and form a single long string extending at the end of this single string, forming a wedge in the shape of a square. Many of them are like a plumb line next to each other. Within the center of the triangle of the two converging wires, the side attached to the stopper is a cylindrical tube with a bolt inside. To make such a single strand of wire inserted into a circular, cylindrical tube on the other side opposite of the blockage head, pull this little wire over the stopper back to the same side to make The cord is pressed over another stopper, and this thin wire is inserted through the cylindrical tube between the two middle wires that converge in a triangle next to the stopper. Each wedge is inserted through it, and each wedge goes through the latch until it is tightened but cannot be pulled back.
