Abstract
A safety buckle of a curtain comprises a curtain body and an upper beam; an auto slide-stop installed within the upper beam for controlling the curtain body to a predetermined position; and a control rope set having a first end and a second end which are at opposite sides. The first end is a rope and the second end. The safety buckle comprises a male pin having a body portion and a guide end. The body portion is positioned at a bottom of the guide end and is connected to a distal end of the rope. A female pin is firmly secured to the upper beam and has a pin seat. The pin seat is formed with a hollow guide hole. When the ropes are pulled, the male pin is separated from the female pin so that the upper beam and the ropes are in a safe state.

A safety buckle of a curtain comprising a curtain body and an upper beam, a distal end of the curtain body being connected to the upper beam;
- an auto slide-stop being installed within the upper beam for controlling the curtain body to a predetermined position;
- and a control rope set having a first end and a second end which are at opposite sides;
- the first end being a rope and the second end being also a rope which are interacted so as to control the curtain body to be folded upwards or to be released downward;
- the safety buckle comprising:
- a male pin comprising a body portion and a guide end, the body portion being positioned at a bottom of the guide end and being connected to a distal end of the rope, wherein the guide has a diameter;
- and
- a female pin firmly secured to the upper beam and comprising a pin seat, the pin seat being formed on one end of a substantially circular hollow guide that protrudes outwardly from the female pin, the hollow guide has a diameter that is smaller than the diameter of the guide end of the male pin, wherein the hollow guide hole comprises an open groove that extends the length of the hollow guide so that when the guide end of the male pin passes through the hollow guide hole, the hollow guide is configured to extrude transversally to permit the passage of the male pin.
