Abstract:
1. 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 having a body portion and a guide end; the body portion being positioned at a bottom of the solid guide end and being connected to a distal end of the rope; and a female pin firmly secured to the upper beam and having a pin seat; the pin seat being formed with a hollow guide hole; a diameter of the hollow guide hole being smaller than a diameter of the solid guide end of the male pin for enforcing the solid guide end of the male pin to be inserted into the hollow guide hole so as to be combined with the pin seat; when the ropes of the control rope set are pulled, the male pin is separated from the female pin so that the upper beam and the ropes are in a safe state, wherein the hollow guide hole has an open groove so that when the guide end of the male pin passes through the hollow guide hole, a substantially equal force is exerted by the solid guide end on the pin seat causing substantial deformation of the pin seat and negligible deformation of the solid guide end.
