the anti-falling frame comprises a connecting part and a fixed clamping part, wherein the anti-falling frame is clamped and fastened at the top of the glass door through the fixed clamping part, and the anti-falling cap is mounted on the anti-falling frame through being matched with the connecting part;
wherein the movable gap between the anti-drop cap and the top of the roller frame is smaller than the movable gap for the roller to drop off from the concave track; after the anti-drop cap is installed, the roller is prevented from being removed from the concave track.
Further, the fixed clamping part comprises two clamping pieces, and a space for clamping the glass door is arranged between the two clamping pieces.
Further, a locating hole is formed in the clamping piece; the roller is provided with a pin shaft, a first positioning baffle plate and a second positioning baffle plate, the first positioning baffle plate and the second positioning baffle plate are respectively arranged on two sides of the glass door through the pin shaft, and the roller is arranged on one side, far away from the glass door, of the second positioning baffle plate through the pin shaft.
The pin shaft penetrates through the positioning hole, and the first positioning baffle plate and the second positioning baffle plate respectively press the two clamping plates to be aligned to the two sides of the glass door.
Further, the connecting portion is arranged on the fixed clamping portion in an inverted trapezoid shape.
Further, a notch corresponding to the inverted trapezoid is arranged in the anti-falling cap.
According to the invention, the pair of the anti-drop frame and the anti-drop cap which can be assembled and combined step by step are additionally arranged on the basis of the common pulley assembly, and the jumping space of the roller in the direction vertical to the concave track on the roller frame is limited by limiting the movable gap between the anti-drop cap and the top of the roller frame, so that the roller is prevented from being separated from the concave track; the pulley assembly has the characteristics of easier installation and operation, can prevent the phenomenon of drop-off prevention and failure caused by the fact that the pulley assembly is not installed in place, and is safer, more stable and more reliable than the traditional common pulley assembly.

Detailed Description
Referring to fig. 1, 2, 3 and 4, an embodiment of the present invention is a drop-proof pulley, which comprises a drop-proof frame 1, a drop-proof cap 2 matched with the drop-proof frame 1, a roller 3 axially arranged on a glass door 4, and a roller frame 5 for providing rail support for the roller 3;
wherein the roller frame 5 is provided with a concave track 51 for sliding the roller 3 carrying the glass door 4 in the roller frame 5;
the anti-falling frame 1 comprises a connecting part 12 and a fixed clamping part, wherein the anti-falling frame 1 is clamped and fastened on the top of the glass door 4 through the fixed clamping part, and the anti-falling cap 2 is mounted on the anti-falling frame 1 through being matched with the connecting part 12;
wherein the movable gap between the anti-falling cap 2 and the top of the roller frame 5 is smaller than the movable gap for the roller 3 to separate from the concave track 51; after the anti-drop cap 2 is installed, the roller 3 is prevented from being detached from the concave rail 51.
Further, the fixing and clamping part comprises two clamping pieces 11, and a space for clamping the glass door 4 is arranged between the two clamping pieces 11.
