Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to an anti-detachment hook. Background Technology

[0002] When using lifting equipment to lift heavy objects, an anti-detachment device needs to be installed on the hook to prevent the lifting device on the hook from detaching.

[0003] Traditional anti-detachment devices consist of a spring-loaded clip installed inside the hook. The spring's elasticity causes the end of the clip to press against the hook tip, closing the hook and preventing the load-bearing equipment from detaching itself once inside. To remove the load, the clip must be forcefully pulled into the hook to disengage from the hook tip, allowing the equipment to be removed. The drawback of this type of anti-detachment hook is that the operator must reach inside the hook to manipulate the clip, which is cumbersome, laborious, and increases the risk of hand injury, posing a significant safety hazard. Summary of the Invention

[0004] This invention addresses the problem of inconvenience and safety hazards associated with existing anti-detachment devices on hooks, which require operators to reach inside the hook to operate a lever. The proposed anti-detachment hook offers enhanced safety. The second blocking component is heavier than the first, causing one end of the first blocking component to abut against the inner wall of the hook tip, sealing the hook opening. Furthermore, this invention incorporates a spring. Initially compressed, the spring's elasticity strengthens the force of the blocking component against the hook tip, improving reliability.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An anti-detachment hook includes a hook body, and two blocking components, namely, a first blocking component and a second blocking component. The first and second blocking components are fixedly connected and form an included angle. A pivot is fixedly connected at the junction of the first and second blocking components, and the pivot is rotatably mounted on the hook body. One end of the first blocking component abuts against the inner wall of the hook tip of the hook body. The second blocking component is sleeved on the hook body, and its weight is greater than that of the first blocking component. The first blocking component can open and close the hook opening of the hook body by rotating with the second blocking component.

[0007] Furthermore, the hook body includes a hook head, a shank, and a hook tip. One end of the hook head is connected to the hook tip, and the other end of the hook head is connected to the shank. The end of the hook head connected to the shank is positioned opposite to the hook tip to form a hook opening between the two.

[0008] Furthermore, a base is provided on the side wall at the junction of the handle and the hook head, and a through hole is provided on the base, through which the rotating shaft passes. The rotating shaft can rotate within the through hole.

[0009] Furthermore, the second blocking member includes two pressure plates, one end of which is fixedly connected to the rotating shaft. When the first blocking member rotates around the rotating shaft, the second blocking member rotates accordingly.

[0010] Furthermore, a bracket is provided on the outer wall of the hook head, and a limiting component is provided on the bracket. The limiting component includes a pull rod, which is a T-shaped rod with a vertical part and a horizontal part. A through hole is provided on the bracket, and the vertical part of the pull rod passes through the through hole. The other ends of the two pressure plates are respectively provided with sliding grooves, and the two ends of the horizontal part of the pull rod are respectively located in the sliding grooves. A spring is also fitted on the vertical part of the pull rod. By providing the limiting component, the reliability of this anti-detachment hook is increased.

[0011] Furthermore, a limit plate is provided on the vertical part of the pull rod, and the two ends of the spring are in contact with the limit plate and the bracket, respectively. The main function of the spring is to provide energy for the pull rod to return to its original position after being pulled upward.

[0012] Furthermore, a circular piece is fixed to the top of the vertical part, and the diameter of the circular piece is larger than the diameter of the second through hole.

[0013] Furthermore, the first blocking component has a U-shaped structure and includes a stop bar and two support rods. The stop bar is located inside the hook head, and one end of each of the two support rods is fixedly connected to the rotating shaft, while the other end is fixedly connected to the stop bar. The stop bar abuts against the hook tip to close the hook opening, or the stop bar separates from the hook tip to open the hook opening.

[0014] The beneficial effects of this utility model through the above technical solution are as follows:

[0015] This utility model includes a first blocking member and a second blocking member rotatably mounted on the hook body. When the first blocking member rotates around the pivot, the second blocking member rotates accordingly. Simultaneously, the second blocking member is heavier than the first blocking member, thus pressing the first blocking member against the hook tip of the hook body to limit its movement and close the hook opening. Furthermore, by setting the limiting component, pulling the lever upwards causes the vertical part of the lever to slide up and down along the through hole, while the horizontal part slides in the groove. This horizontal part also rotates relative to the pressure plate, causing the lever to swing up and down with the pressure plate. This, in turn, opens and closes the hook opening of the hook body. Compared to the method where the operator needs to reach into the hook to pull a lever, this method is safer. Moreover, when the lever abuts against the hook tip to close the hook opening, the spring force strengthens the force of the lever against the hook tip, improving reliability. In addition, throughout the entire process, the operator's hands operate outside the hook, effectively avoiding crushing accidents. It has the advantages of safe operation, good anti-detachment effect, and stable and reliable operation. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1-5As shown, this embodiment provides an anti-detachment hook, including a hook body, and two blocking components. The first and second blocking components are fixedly connected and form an angle between them. A rotating shaft 1 is fixedly connected at the junction of the first and second blocking components, and the rotating shaft 1 is rotatably mounted on the hook body. One end of the first blocking component abuts against the inner wall of the hook tip of the hook body. The second blocking component is sleeved on the hook body, and its weight is greater than that of the first blocking component. When the first blocking component rotates around the rotating shaft 1, the second blocking component rotates accordingly. Simultaneously, since the weight of the second blocking component is greater than that of the first blocking component, the second blocking component can press down on the first blocking component at the hook tip 4 of the hook body, thus limiting its position and closing the hook opening.

[0025] Please refer to this again. Figure 3 The hook body includes a hook head 2, a handle 3 and a hook tip 4. One end of the hook head 2 is connected to the hook tip 4, and the other end of the hook head 2 is connected to the handle 3. The end of the hook head 2 connected to the handle 3 is arranged opposite to the hook tip 4 to form a hook opening between the two.

[0026] In this embodiment, a base 5 is provided on the side wall at the junction of the handle 3 and the hook head 2. A through hole 6 is provided on the base 5, and the rotating shaft 1 passes through the through hole 6. The rotating shaft 1 can rotate within the through hole 6.

[0027] Please refer to this again. Figure 4 The second blocking component includes two pressure plates 7, one end of which is fixedly connected to the rotating shaft 1. When the first blocking component rotates around the rotating shaft 1, the second blocking component rotates accordingly.

[0028] Furthermore, a bracket 8 is provided on the outer side wall of the hook head 2. A limiting component is provided on the bracket 8. The limiting component includes a pull rod 9. The pull rod 9 is a T-shaped rod. The T-shaped rod includes a vertical part 901 and a horizontal part 902. A through hole 10 is provided on the bracket 8. The vertical part 901 of the pull rod 9 passes through the through hole 10. The other ends of the two pressure plates 7 are respectively provided with sliding grooves 11. The two ends of the horizontal part 902 of the pull rod 9 are respectively located in the sliding grooves 11. A spring 12 is also fitted on the vertical part 901 of the pull rod 9.

[0029] By setting a limiting component, this utility model allows the horizontal part 902 of the pull rod 9 to slide in the groove 11 while the vertical part 901 slides up and down along the through hole 10. At the same time, the horizontal part 902 will also rotate relative to the pressure plate 7. Therefore, the pull rod 9 will swing up and down with the pressure plate 7, and the stop rod 14 will open and close the hook mouth of the hook body. Compared with the method of the operator having to put his hand into the hook to pull the card, the operation is safer.

[0030] It is worth mentioning that, initially, the spring 12 is in a compressed state. When the stop lever 14 abuts against the hook tip 4 to close the hook opening, the elastic force of the spring 12 strengthens the force of the stop lever 14 against the hook tip 4, thus improving reliability.

[0031] Furthermore, the vertical portion 901 of the pull rod 9 is also provided with a limiting plate 13, and the two ends of the spring 12 are in contact with the limiting plate 13 and the bracket 8, respectively. The spring 12 also provides energy for the pull rod 9 to return to its original position after being pulled upward, and the spring 12 used for returning to its original position will not affect the normal use of the hook.

[0032] Furthermore, a circular piece is fixed to the top of the vertical part 901, and the diameter of the circular piece is larger than the diameter of the second through hole 10. By setting the circular piece, the pull rod 9 is prevented from falling out of the second through hole 10.

[0033] Please refer to this again. Figure 4 The first blocking component has a U-shaped structure and includes a stop bar 14 and two support rods 15. The stop bar 14 is located inside the hook head 2. One end of each of the two support rods 15 is fixedly connected to the rotating shaft 1, and the other end is fixedly connected to the stop bar 14. The stop bar 14 abuts against the hook tip 4 to close the hook opening, or the stop bar 14 separates from the hook tip 4 to open the hook opening.

[0034] The working principle of this utility model is as follows:

[0035] When the hook is lifting goods, pull the lever 9 upwards. The lever 9 causes the pressure plate 7 to swing upwards, and the stop lever 14 moves away from the hook tip 4. When the stop lever 14 separates from the hook tip 4 and opens the hook opening, put in the item that needs to be hooked by the hook head 2, and then release the lever 9. The lever 9 slides downwards to return to its original position under the action of the spring 12. The stop lever 14 moves towards the hook tip 4. When the stop lever 14 abuts against the hook tip 4, it closes the hook opening and prevents the item hooked in the hook head 2 from falling out.

[0036] In summary, throughout the entire use of this utility model, the operator's hands operate outside the hook, effectively avoiding crushing accidents. It has the advantages of safe operation, good anti-detachment effect, and stable and reliable operation.
