Please refer to Figures 1 - 5 , a novel anti - detachment device for a lifting hook, comprising: a lifting hook body 1, an anti - detachment component 2 is arranged outside the top end of the lifting hook body 1, which is used to prevent the heavy object from slipping during the lifting process. Angle - adjusting components 3 are symmetrically arranged on the front and rear sides of the left end of the anti - detachment component 2, which are used to adjust the angle of the anti - detachment component 2. The anti - detachment component 2 includes an anti - detachment plate 201 arranged at the top end of the lifting hook body 1. A rotating groove 202 is opened at the center of the left end of the anti - detachment plate 201. The inner and outer walls at the front and rear ends of the rotating groove 202 are mutually attached to the outer walls at both ends of the lifting hook body 1. A rotating shaft 203 is rotatably connected to the top end of the lifting hook body 1. Both ends of the rotating shaft 203 penetrate the outer walls at both ends of the lifting hook body 1 and are rotatably connected to both ends of the anti - detachment plate 201. The anti - detachment component 2 further includes a fitting groove 204 opened at the center of the right end of the anti - detachment plate 201. The inner and outer walls at both ends of the fitting groove 204 are mutually attached to the outer wall of the lifting hook body 1. The anti - detachment component 2 further includes anti - detachment blocks 205 fixedly connected to the outer walls at both ends of the right side of the lifting hook body 1. The bottom end of the anti - detachment block 205 is mutually attached to the top end of the anti - detachment plate 201. The anti - detachment plate 201 rotates around the rotating shaft 203, so that the rotation directions of the left end and the right end of the anti - detachment plate 201 are completely opposite. The anti - detachment blocks 205 are distributed in a slanting shape from the lower left to the upper right, so as to resist the right end of the anti - detachment plate 201 and prevent the binding rope from slipping off the lifting hook body 1.

[0024] Please refer to Figures 2 - 5, the angle adjustment assembly 3 includes a fixing plate 301 fixedly connected to the outer wall of the hook body 1.

When the output end of the electric telescopic rod 302 drives the mounting seat 303 to move upward, the L-shaped connecting rod 304 is driven to move upward through the mounting seat 303. The connecting ball 305 is driven to move upward through the L-shaped connecting rod 304. The chute 306 is driven to move upward through the connecting ball 305, so that the left end of the anti-disengagement plate 201 is driven to move upward, causing the anti-disengagement plate 201 to rotate around the rotating shaft 203. At the same time, the left end of the anti-disengagement plate 201 drives the chute 306 to rotate upward, thereby driving the connecting ball 305 to rotate through the chute 306. The L-shaped connecting rod 304 is driven to rotate through the connecting ball 305. The mounting seat 303 is driven to rotate through the L-shaped connecting rod 304, causing rotation between the mounting seat 303 and the output end of the electric telescopic rod 302. At the same time, the electric telescopic rod 302 limits the mounting seat 303, the mounting seat 303 limits the L-shaped connecting rod 304, and the L-shaped connecting rod 304 limits the connecting ball 305, so that the vertical direction of the connecting ball 305 remains unchanged. Furthermore, the chute 306 slides relative to the connecting ball 305, thereby realizing the angle adjustment of the anti-disengagement plate 201.

[0025] Working principle and use process: when it is necessary to hook a heavy object, the electric telescopic rod 302 is started, and the mounting seat 303 is driven upward by the output end of the electric telescopic rod 302, and the L-shaped connecting rod 304 is driven upward by the mounting seat 303, and the connecting ball 305 is driven upward by the L-shaped connecting rod 304, and the slide groove 306 is driven upward by the connecting ball 305, thereby lifting the left end of the anti-drop plate 201 upward, so that the anti-drop plate 201 rotates around the rotating shaft 203 as the center, and at the same time, the right end of the anti-drop plate 201 rotates downward, so that the right end of the anti-drop plate 201 is separated from the hook tip of the hook body 1, and the anti-drop plate 201 moves downward. The hook body 1 is used to hook the heavy object, and then the electric telescopic rod 302 is started, and the mounting seat 303 is driven to move downward through the output end of the electric telescopic rod 302, and the L-shaped connecting rod 304 is driven to move downward through the mounting seat 303, and the connecting ball 305 is driven to move downward through the L-shaped connecting rod 304, and the slide groove 306 is driven to move downward through the connecting ball 305, so that the left end of the anti-drop plate 201 moves downward, so that the anti-drop plate 201 rotates around the rotating shaft 203, so that the right end of the anti-drop plate 201 rotates upward, so that the right end of the anti-drop plate 201 is in close contact with the anti-drop block 205, and is thereby resisted by the anti-drop block 205.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
