Fall arrester improved structure

The present invention relates to a fall arrester, and in particular to a frame structure of a hanger by assembling a scroll spring and a frame of the hanger, so that the component has a good installation of the fall arrester structure.

According to the name "anti-dropper", it is used when the exterior wall of a building or the glass wall of a high-rise building is cleaned and used to cushion the workers from accidentally falling, and the protective equipment waiting for rescue can be hung. As shown in FIG. 1 to FIG. 2, the patent case of the anti-dropper spring assembly mechanism of the anti-dropping device of the Chinese Patent Publication No. M520912 mainly includes a bracket 10, a rotating drum 40, a biasing member 60 and a scroll spring 70. The bracket 10 has a top plate 11 and a side plate 12A, 12B extending downward from the left and right sides of the top plate 11. A chamber 13 is defined between the two side plates 12A, 12B, and the two side plates 12A, 12B each have a heart. The hole 15 is provided with a middle shaft 20, and a flange 14 is bent forward and backward. The inner side of the side plate 12A is screwed to a brake ring 16, and the brake ring 16 is provided with a ratchet hole 161. The top plate 11 is provided. A pivoting ring 30 is pivoted. The rotating drum 40 has a shaft hole 41. The rotating shaft 40 is provided with a socket 42. The drum 40 is provided with a lifeline 50 for fixing the outer circumference of the drum 40. After the one end is wound, the other end of the lifeline 50 is extended downwardly to the chamber 13, and after passing through a buffer bag 51, the other end of the lifeline 50 is mounted with a hook hooked to the user. 52. The biasing member 60 includes a symmetrical two-cylinder block 61 and two return springs 62. The centrifugal block 61 is pivotally connected to the socket 42. The return spring 62 is disposed between the rotating drum 40 and the centrifugal block 61. Thereby the centrifugal block 61 has The scrolling spring 70 is wound around a frame 71, and the frame 71 is mounted in the chamber 13 and is provided with a stopper 711 protruding from the chamber 13, and the stopper 711 is received by The slanted flange 14 of the top plate 11 is clamped, and the large diameter end 702 of the scroll spring 70 is fixed to the stopper 711. The small diameter end 701 of the scroll spring 70 is positioned at the drum 40 away from the connection. The other end of the seat 42.

During installation, the drum 40 and the socket 71 are mounted in the chamber 13 of the bracket, and the center shaft 20 is inserted through the core hole 15 of the side plate 12B of the bracket 10, and then passes through the drum 40. The shaft hole 41 is then passed through the other side plate 12A of the bracket 10, and is finally riveted and fixed to the center shaft 20 by the mounting fastener 21.

Since the small diameter end 701 of the scroll spring 70 is positioned at the other end of the rotating drum 40 away from the socket 42, the small diameter end 701 of the scroll spring 70 must be positioned before the drum 40 is away from the socket 42 in assembly. At the other end, the operator holds the drum 40 in one hand (such as the right hand), and the other hand (such as the left hand) holds the frame 71 to rotate, so that the scroll spring 70 is tightened at a predetermined tightness, right hand. At the same time, the frame 71 is moved together with the rotating drum 40 into the chamber 13, and the shaft hole 41 of the rotating drum 40 is adjusted to face the core hole 15 of the side plate 12A, and the frame 71 and the rotating drum 40 are released by the right hand. The center shaft 20 can be picked up by the core hole 15 of the side plate 12B of the bracket 10, and then passed through the shaft hole 41 of the drum 40 and passed through the other side plate 12A of the bracket 10.

During the assembly operation, once the handle 71 and the drum 40 are released, the restoring force of the scroll spring 70 drives the frame 71 to rotate until the stop 711 is stopped by the flange 14 of the bracket 10, so The scroll spring 70 is loosened at a predetermined tightness. It is important that the frame 71 is blocked by the flange 711 on the outer peripheral side and blocked by the flange 14 of the bracket. The positioning braking force falls on the frame 71. The one side point is not stable, and the arm frame 71 is released by the right hand, and the elastic force of the scroll spring 70 immediately drives the frame 71 to rotate, which affects the shaft hole 41 of the rotating drum 40 and is not easily aligned with the core hole 15 of the side plate 12B. Cause the right hand to pick up The middle shaft 20 penetrates into the core hole 15 of the side plate 12B and does not easily penetrate the shaft hole 41 of the drum 40. Therefore, the right hand has to be biased to adjust the position of the drum 40, so the right hand 20 is released from the right hand until the drum 40 is The two sides of the shaft hole 41 are respectively connected to the side plate 12B of the left side of the bracket 10 and the core hole 15 of the right side plate 12A, and the left hand holding the bracket 10 is held together with the rotating drum 40, so that the right hand picks up the center shaft 20 again. The core hole 15 of the side plate 12B of the bracket 10 penetrates, passes through the shaft hole 41 of the drum 40, and passes through the other side plate 12A of the bracket 10, and finally is riveted with the mounting fastener 21 and the center shaft 20. Fixed together, obviously there is still a fixed positioning in the assembly, which is time-consuming and troublesome.
