DETAILED DESCRIPTION

[0025] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1: A self-locking hook for high-altitude operations, see Figure 1-Figure 5 As shown, it includes a hook body 1, a rotating shaft 2, a locking block 4, a torsion spring 3, a button 5, a return spring 7, a protruding rod 8, a bolt 14, a rope ring 12, a slide rail 9, a protective cover 10, a reset spring 11, a circular clamping plate 13, a protective cover 15 and an anti-slip pad 17. The hook body 1 is rotatably connected with the rotating shaft 2, and the locking block 4 is connected to the rotating shaft 2 by welding. The locking block 4 is made of metal material. A torsion spring 3 is sleeved on the rotating shaft 2. The two ends of the torsion spring 3 are respectively connected to the locking block 4 and the hook body 1. The torsion spring 3 is used to assist the rotating shaft 2 to reverse and reset. A button 5 is slidably connected to the locking block 4. A protrusion is connected to the upper part of the button 5. A return spring 7 is connected between the two buttons 5. The return spring 7 is used to assist the button 5 to move and reset. The lower part of the button 5 is connected to the protruding rod 8. The protruding rod 8 is connected to the hook body 1 is clamped, a bolt 14 is threadedly connected to the lower part of the hook body 1, and a rope ring 12 is connected to the lower end of the bolt 14. The rope ring 12 is used to tie the rope, a slide rail 9 is connected to the lock block 4, and a protective cover 10 is slidably connected to the slide rail 9. The protective cover 10 is convex in shape, and both sides of the protective cover 10 are used to cover the button 5. A reset spring 11 is connected between the protective cover 10 and the lock block 4. The reset spring 11 is used to assist the protective cover 10 in moving and resetting, and the convex block on the upper part of the button 5 is blocked by the protective cover 10. A circular clamping plate 13 for reinforcement is connected to the bolt 14 by welding, and the circular clamping plate 13 is clamped with the hook body 1, and a protective cover 15 distributed up and down is embedded and connected to the hook body 1. An anti-skid pad 17 for anti-skid is embedded and connected to the hook body 1, and the anti-skid pad 17 fully covers the inner wall of the hook body 1.

[0027] First, the staff puts the hook body 1 on the connection structure of the building's exterior wall, then moves the protective cover 10 upward to a suitable position, the return spring 11 is stretched, and then squeezes the button 5 to drive the protruding rod 8 to move inward and disengage from the hook body 1, the return spring 7 is compressed, and then the lock block 4 is rotated backward to a suitable angle, the torsion spring 3 is deformed, and then the hook body 1 is hung on the connection structure, the anti-slip pad 17 increases the friction between the hook body 1 and the connection structure to prevent the hook body 1 from shaking, and after hanging, the staff releases the lock block 4, and the torsion spring 3 returns to its original shape The locking block 4 is rotated forward to reset, and then the button 5 is released, and the return spring 7 returns to its original state, so that the button 5 drives the protruding rod 8 to move outward and engage with the hook body 1, thereby reinforcing the locking block 4 on the hook body 1, thereby achieving the purpose of self-locking and facilitating quick use. Then the protective cover 10 is released, and the return spring 11 returns to its original state, so that the protective cover 10 moves downward to block the button 5, to prevent the outside world from accidentally touching the button 5 to cause the locking block 4 to rotate, and the staff ties the safety rope to the rope ring 12, and the circular clamping plate 13 reinforces the bolt 14 to prevent the bolt 14 from rotating and separating from the hook body 1.

[0028] Example 2: Based on Example 1, refer to Figure 1 and Figure 2 As shown, it also includes an induction magnet 6 and an alarm 16. The induction magnet 6 is embedded and connected inside the hook body 1. The locking block 4 is attracted to the induction magnet 6. The induction magnet 6 is used to reinforce the locking block 4. The rear part of the hook body 1 is connected to the alarm 16 by bolts. The alarm 16 is used for alarming. The induction magnet 6 is electrically connected to the alarm 16.

[0029] When the lock block 4 rotates forward and does not contact the induction magnetic block 6, the induction magnetic block 6 transmits information to the alarm 16, and the alarm 16 sounds to attract the attention of the staff, so that the staff can adjust the rotation angle of the lock block 4 in time to avoid the self-locking deviation of the lock block 4 causing installation accidents.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
