Embodiment Construction

[0025] Such as Figure 1-2 As shown, an anti-falling hook includes a hook 1 and a cable plate 2; the hook tail position of the hook 1 is rotatably connected to the tail end of the cable plate 2; the hook 1 is connected to the cable plate 2 A torsion spring 3 is arranged between the cable boards 2, so that the cable board 2 has an elastic force to rotate outward. When the support rod is stuck into the hook, the cable board bounces outward to form a closed ring with the hook. Prevent the supporting rod from protruding; the hook head position of the suspension hook 1 is provided with a blocking wall 4, and the blocking wall 4 is in contact with the top surface of the cable plate 2, and the length of the contact surface is 1-2 cm. The length of the contact surface is 1.5cm, which changes the previous point contact, greatly increases the blocking area, and prevents the cable board from being deformed and detached from the blocking.

Abstract

The invention discloses a falling-off prevention hook. The falling-off prevention hook comprises a hook body and a rope clamping plate. The hook tail portion of the hook body is rotationally connected with the tail end of the rope clamping plate. A torsion spring is arranged between the hook body and the rope clamping plate so that the rope clamping plate can have outward-rotating elastic force. A blocking wall is arranged on the hook head position of the hook body and makes contact with the top end face of the rope clamping plate. According to the falling-off prevention hook, the rope clamping plate is hinged to the hook tail position of the hook body, the torsion spring is arranged between the rope clamping plate and the hook body, outward tension of the rope clamping plate is kept, the blocking wall is arranged on the position, in cooperation with the hook head of the hook body, of the top end of the rope clamping plate and makes contact with the rope clamping plate face, the safety factor is increased, the rope clamping plate is effectively prevented from being separated from the hook body, and hoisting safety is guaranteed.

Description

technical field [0001] The invention relates to the field of hooks, in particular to an anti-falling hook. Background technique [0002] At present, the cable plates on the known chain hoists and chain hoist hooks have no grooves, and the cable plates and the hooks are in point contact or line contact. The contact area is small and not reliable, so the cable plates are easy to Shaking left and right, there is even a risk that the cable board will break away from the hook and cause the cable board to fail. [0003] Therefore, there is an urgent need for a suspension hook that improves the contact area between the cable board and the suspension hook, improves the safety factor, and prevents the cable board from decoupling. Contents of the invention [0004] The object of the present invention is to provide an anti-falling hook, which solves the problem that the cable plate of the existing hook is easy to decouple. [0005] In order to solve the problems of the technologies...
