Detailed Description

The invention is further explained below with reference to the drawings:

in the present specification, terms indicating orientation such as "vertical", "horizontal", "inside" and "outside" are used for convenience of structural description, and all refer to relative positions.

Referring to fig. 2 to 4, a pull rope fixing device includes a fixing frame 2 for holding a door leaf 5, and a lifting frame 3 detachably fixed to the fixing frame 2; the fixed frame 2 comprises two vertical parallel side plates 21, a top plate 22 connecting the top ends of the two side plates 21, and a pressing piece 23 which is matched through threads and vertically penetrates through one side plate 21 and is used for pressing the door leaf 5; the hoisting frame 3 comprises a horizontal hoisting plate 31 and a mounting plate 32 perpendicular to one end of the hoisting plate 31, the mounting plate 32 can be fixed with any one of the side plates 21, and the hoisting plate 31 is lower than the top plate 22 to form a step part 4.

When the door frame is used, the fixed frame 2 can be clamped on the top edge of the door leaf 5, the pressing piece 23 is positioned on the inner side of the door leaf 5, namely the side opposite to the step frame of the door frame 6, usually the indoor side, then the fixed frame 2 and the door leaf 5 are locked and fixed by screwing the pressing piece 23, the hoisting frame 3 can be fixed on the inner side of the door leaf 5 of the fixed frame 2 and also can be fixed on the outer side of the door leaf 5 of the fixed frame 2, and when the hoisting frame 3 is fixed on the outer side of the door leaf 5 of the fixed frame 2, the step part 4 between the hoisting plate 31 and the top plate 22 can bypass the step frame of the door frame 6; the pull rope is hoisted at the outer end of the hoisting frame 3.

When the hoisting frame 3 is fixed towards the outer side of the door leaf 5, the step part 4 can bypass the step frame of the door frame 6 and cannot interfere with the door frame 6; and when the hoisting frame 3 is fixed towards the inner side of the door leaf 5, the hoisting frame 3 can be fixed on one side of the fixed frame 2 close to the pressing piece 23, so that the fixed frame 2 cannot interfere with the door frame 6, and therefore, the stay cord fixing device can be suitable for various installation modes such as whether the door frame 6 has a step frame and towards the inner side or the outer side of the door leaf 5.

The pressing piece 23 is vertically matched with the side plate 21 through threads, and the pressing piece 23 can be enabled to translate towards the inner side of the fixed frame 2 by screwing the pressing piece 23, so that the door leaf 5 is pressed. In one embodiment, the pressing member 23 includes a screw 231 passing through the side plate 21, a pressing disc 232 disposed at an inner end of the screw 231, and a stem 233 disposed at an outer end of the screw 231.
