Description

Technical Field

[0001] This utility model relates to a safety hook with emergency protection against breakage, belonging to the field of hook technology. Background Technology

[0002] The hook has a precise overall structure. The hook body is made of high-strength alloy and has a strong load-bearing capacity, which can steadily support heavy objects. The hook opening and closing part is equipped with a reliable locking mechanism. Some of them adopt an automatic snap-lock design, which automatically locks the hook the moment it is hooked to prevent accidental disengagement.

[0003] Traditional hooks have a simple structure. If the hook breaks at the bend due to excessive load, external impact, or long-term use, the suspended object will fall instantly, which may damage the property, damage the working environment, or even cause serious injury to people around, thus posing a great safety hazard.

[0004] Therefore, it is urgent to improve the safety hook with emergency breakage protection to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a safety hook with emergency protection against breakage. Manually pressing the limiting block compresses the first spring to store energy, making it easy to hang an object on the hook body. After releasing the spring, the potential energy is released, allowing the limiting block to pass through the limiting hole. Rotating the limiting block allows it to abut against the inner wall of the locking tongue, securely connecting the pull rope and the locking tongue. If the bend in the hook body breaks, the object can be suspended by the pull rope, achieving emergency protection for the suspended object and preventing it from falling directly, thereby ensuring the safety of the object, the surrounding environment, and personnel.

[0027] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] like Figures 1-5 As shown, the safety hook with emergency protection effect in this embodiment includes a hook body 1, a locking tongue 2 is hinged to the hook body 1 by a pivot, a limit hole 3 is provided on the locking tongue 2, and a pull rope groove 4 is provided on the hook body 1. A pull rope 5 is provided inside the pull rope groove 4. The pull rope 5 is made of several steel wires twisted together. One end of the pull rope 5 is fixedly connected to the inner end face of the pull rope groove 4, and the other end of the pull rope 5 is fixedly connected to a snap-fit ​​mechanism 6. A rubber pad 7 is provided on the inner side of the hook body 1. Anti-slip texture 8 is provided on the rubber pad 7. The anti-slip texture 8 is located at the bend of the rubber pad 7.

[0029] The latching mechanism 6 includes a slider 61, which is fixedly connected to one end of the pull rope 5. A first spring 62 is provided on one side of the slider 61, and one end of the first spring 62 is fixedly connected to the slider 61. A rotating rod 63 is rotatably connected to the other side of the slider 61. The end of the rotating rod 63 away from the slider 61 passes through the limiting hole 3 and is fixedly connected to a limiting block 64, which corresponds to the limiting hole 3. A groove 9 is provided on the hook body 1, which is connected to the pull rope groove 4. The slider 61 is slidably disposed inside the groove 9. The end of the first spring 62 away from the slider 61 is fixedly connected to the inner wall of the groove 9. When the limiting block 64 is manually pressed, the limiting block 64 slides inside the groove 9, and the rotating rod 63 drives the slider 61 to move, so that the first spring 62 is compressed and stores elastic potential energy. Then, an object is hung on the hook body 1, and then the limiting block 64 is released. The first spring 62 releases its elastic potential energy, driving the slider 61, the rotating rod 63, and the limiting block 64. When the limiting block 64 passes through the limiting hole 3 on the locking tongue 2, the limiting block 64 is rotated, and the rotating rod 63 rotates accordingly, so that the limiting block 64 abuts against the inner wall of the locking tongue 2, thereby firmly connecting the pull rope 5 to the locking tongue 2. At the same time, the rubber pad 7 on the inner side of the hook body 1 and the anti-slip texture 8 at the bend can increase the friction with the suspended object and prevent the object from slipping. If the bend 1 of the hook body is unfortunately broken, the object can be suspended by the pull rope 5, realizing emergency protection for the suspended object and preventing the object from falling directly, thereby ensuring the safety of the object, the surrounding environment and personnel.

[0030] Furthermore, such as Figures 1-5 As shown, two connecting grooves 10 are provided on the inner side of the hook body 1. The two connecting grooves 10 are respectively located on both sides of the pull rope groove 4. Two connecting blocks 11 are fixedly installed on the rubber pad 7. The two connecting blocks 11 are respectively glued to the inside of the two connecting grooves 10 by adhesive. The rubber pad 7 is glued to the connecting grooves 10 by the two connecting blocks 11 fixed on it with adhesive, which can firmly install the rubber pad 7 on the inner side of the hook body 1. This allows the rubber pad 7 and its anti-slip texture 8 to increase the friction with the suspended object, effectively prevent the object from slipping, and enhance the safety of the hook.

[0031] Furthermore, such as Figures 1-5As shown, a locking block 12 is fixedly installed on one side of the hook body 1. An arc-shaped slot 13 is provided on the locking block 12. A connecting shaft 14 is slidably arranged inside the arc-shaped slot 13. The connecting shaft 14 is fixedly installed on the locking tongue 2. A second spring 15 is provided between the hook body 1 and the locking tongue 2. One end of the second spring 15 is fixedly connected to the hook body 1, and the other end of the second spring 15 is fixedly connected to the locking tongue 2. A locking groove 17 is provided on one side of the locking tongue 2. The locking groove 17 abuts against the hook head end of the hook body 1. When the hook body 1 needs to suspend an object, the locking tongue 2 is pressed, and the second spring 15 contracts, storing elastic potential energy. At this time, the connecting shaft 14 of the locking tongue 2 slides in the arc-shaped slot 13 of the locking block 12, thus facilitating the hanging of the object on the hook body 1. After the object is suspended on the hook body 1, the locking tongue 2 is released, and the second spring 15 releases elastic potential energy, causing the locking tongue 2 to return to its original position, so that the locking groove 17 abuts against the hook head end of the hook body 1, preventing the object from accidentally slipping off, thereby ensuring the suspension safety.

[0032] Furthermore, such as Figures 1-5 As shown, the hook body 1 has a safety belt hole 16, which is used to thread a safety rope through, thereby facilitating the binding of the safety rope to the hook.

[0033] like Figures 1-5 As shown, the principle of the safety hook with emergency breakage protection provided in this embodiment is as follows:

[0034] In use, first, manually press the limiting block 64. The limiting block 64 slides inside the slide groove 9, driving the slider 61 to move via the rotating rod 63. This compresses the first spring 62 and stores elastic potential energy. Next, press the latch 2. The second spring 15 contracts and stores elastic potential energy. The connecting shaft 14 of the latch 2 slides within the arc-shaped slot 13 of the locking block 12. Then, hang the object on the hook body 1. Afterward, release the latch 2. The second spring 15 releases its elastic potential energy, causing the latch 2 to return to its original position, so that the locking groove 17 abuts against the hook end of the hook body 1. At this point, release the limiting block 64. The first spring 62 releases its elastic potential energy, driving the slider 61, rotating rod 63, and limiting block 64 to move. When the limiting block 64 passes through the limiting hole 3 on the locking tongue 2, the limiting block 64 is rotated, and the rotating rod 63 rotates accordingly, so that the limiting block 64 abuts against the inner wall of the locking tongue 2, thereby firmly connecting the pull rope 5 to the locking tongue 2. If the bend 1 of the hook body is unfortunately broken, the object can be suspended by the pull rope 5 to achieve emergency protection for the suspended object and prevent the object from falling directly.
