Description

Technical Field

[0001] This utility model relates to the field of hook technology, and in particular to a hook with an enhanced load-bearing surface. Background Technology

[0002] A lifting hook is a basic lifting tool used in hoisting operations, typically composed of a hook body, lifting ring, and lifting eyelet. It features a simple and reliable structural design, wide applicability, and good load-bearing capacity, enabling it to perform tasks such as lifting, transferring, and positioning materials in various scenarios. Traditional lifting hooks, due to their durability, ease of maintenance, and versatility, have become the basic equipment for most hoisting operations and are widely used in industries such as manufacturing, construction, and logistics.

[0003] However, due to the limitations of the shape of the load-bearing surface, traditional cast iron hooks are often deformed and damaged, which can increase their angle or damage the suspended items. The lifting eye and the load-bearing surface of the hook body are often not perpendicular, and the stress distribution is relatively concentrated. This can easily lead to local stress concentration at sharp edges and contact points, increasing the risk of fatigue failure and breakage.

[0004] Therefore, those skilled in the art have provided a hook with an enhanced load-bearing surface to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hook with an enhanced load-bearing surface. The hook's shackle has a hook eye perpendicular to the load-bearing surface of the hook body, allowing for a more even distribution of force along the load-bearing surface and reducing stress concentration at sharp corners. This reduces localized concentrated loads on hard and heavy objects. Furthermore, an arc-shaped steel plate is installed on the load-bearing surface of the hook body, protecting the load-bearing surface of the suspended object and improving the wear resistance and damage resistance of the contact surface. This prevents localized wear or cracks from spreading inward due to direct metal contact, thereby enhancing the hook's applicability and safety.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A force-reinforced hook includes a hook body, a connector fixedly connected to the upper end of the hook body, a lifting ring fixedly connected to the upper surface of the connector, an arc-shaped steel plate fixedly connected to the middle of the inner wall of the hook body, a hook tip fixedly connected to the end of the hook body away from the connector, a groove formed on the inner wall of the hook tip, a fixing seat fixedly connected to the upper end of one side of the outer wall of the connector, an arc-shaped lever hinged to one side of the outer wall of the fixing seat, and a hook fixedly connected to the end of the arc-shaped lever away from the fixing seat.

[0008] Through the above technical solution, the hook has a slot on the hook tip and a hook on the arc-shaped lever. Under the elastic action of the elastic arc plate, they are locked together, which can help to share a small part of the load borne by the hook body. Under the pull of the load force, the possibility of the arc-shaped lever opening accidentally is reduced, further improving the safety of the hook.

[0009] Furthermore, all the arc-shaped steel plates are made of S355 structural steel;

[0010] Through the above technical solutions, S355 structural steel material can improve the fatigue life and durability of curved steel plates.

[0011] Furthermore, multiple triangular plates are fixedly connected to the outer walls of both the front and rear ends of the hook body;

[0012] The above technical solution improves the stability between the curved steel plate and the hook body.

[0013] Furthermore, the slot and the hook engage in a snap-fit ​​relationship;

[0014] The above technical solution enables the arc-shaped lever to engage and fit snugly with the hook tip.

[0015] Furthermore, a first positioning groove is provided on the upper end of the outer wall of the connector near the arc-shaped lever, and a second positioning groove is provided on the upper end of the inner wall of the arc-shaped lever near the hook body.

[0016] The above technical solution enables the elastic arc plate to restore the position between the arc-shaped lever and the connecting piece.

[0017] Furthermore, the inner walls of both the first and second positioning grooves are fitted with elastic arc sheets.

[0018] The above technical solution helps the arc-shaped lever to restore its position.

[0019] Furthermore, the elastic arc sheet is made of stainless steel;

[0020] Through the above technical solutions, stainless steel material can improve the corrosion resistance and durability of the elastic arc sheet.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model proposes a load-bearing surface enhanced hook. Compared with most traditional hooks, the hook has a structure in which the lifting eye on the lifting ring is perpendicular to the load-bearing surface of the hook body. This allows the force to be distributed more evenly along the load-bearing surface, reducing the concentrated stress at sharp corners. For hard and heavy objects, it reduces the local concentrated load. In addition, a steel arc-shaped steel plate is installed on the load-bearing surface of the hook body. The arc-shaped steel plate protects the load-bearing surface of the suspended object, thereby improving the wear resistance and damage resistance of the contact surface with the suspended object. It avoids the local wear or crack propagation caused by direct metal contact, thereby improving the applicability and safety of the hook.

[0023] 2. The present invention proposes a force-reinforced hook, which, compared with most traditional hooks, has a slot on the hook tip and a hook on the arc-shaped lever. Under the elastic action of the elastic arc plate, they are locked together, thereby helping to share a small part of the load borne by the hook body. Under the pull of the load force, the possibility of the arc-shaped lever opening accidentally is reduced, further improving the safety of the hook. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] One embodiment provided by this utility model:

[0031] Reference Figure 1 , 23. A load-bearing surface reinforced hook includes a hook body 1, a connector 2 fixedly connected to the upper end of the hook body 1, a lifting ring 3 fixedly connected to the upper surface of the connector 2, an arc-shaped steel plate 4 fixedly connected to the middle of the inner wall of the hook body 1, a hook tip 6 fixedly connected to the end of the hook body 1 away from the connector 2, a groove 7 opened on the inner wall of the hook tip 6, a fixed seat 8 fixedly connected to the upper end of the outer wall of one side of the connector 2, an arc-shaped lever 9 hingedly connected to one side of the outer wall of the fixed seat 8, and a hook 10 fixedly connected to the end of the arc-shaped lever 9 away from the fixed seat 8. The hook has a groove 7 opened on the hook tip 6 and a hook 10 set on the arc-shaped lever 9. Under the elastic action of the elastic arc plate 13, they are locked together, thereby helping to share a small part of the load borne by the hook body 1. Under the pull of the load force, the possibility of the arc-shaped lever 9 being accidentally opened is reduced, further improving the safety of the hook.

[0032] Reference Figure 1 , 2 3. The curved steel plate 4 is made of S355 structural steel. The S355 structural steel material can improve the fatigue life and durability of the curved steel plate 4. Multiple triangular plates 5 are fixedly connected to the outer walls of the front and rear ends of the hook body 1, thereby improving the firmness between the curved steel plate 4 and the hook body 1. The slot 7 and the hook 10 are engaged, so that the curved lever 9 can be engaged and fitted together with the hook tip 6. The upper end of the outer wall of the connector 2 near the curved lever 9 is provided with a first positioning groove 11, and the upper end of the inner wall of the curved lever 9 near the hook body 1 is provided with a second positioning groove 12, so that the elastic arc plate 13 can restore the position between the curved lever 9 and the connector 2. The inner walls of the first positioning groove 11 and the second positioning groove 12 are engaged with elastic arc plates 13, thereby assisting the curved lever 9 to complete the position restoration. The elastic arc plate 13 is made of stainless steel, which can improve the corrosion resistance and durability of the elastic arc plate 13.

[0033] Working principle: First, the hook is installed on the required equipment through the eyelet on the lifting ring 3. When in use, the rope wrapped around the lifting material is placed at the arc-shaped lever 9. By pressing it into the arc-shaped steel plate 4 on the hook body 1, the deformed arc-shaped lever 9 is reset by the elastic arc plate 13 (which has a low thickness and can be folded at a large angle, thus assisting the arc-shaped lever 9 in resetting). This allows the hook 10 to engage with the slot 7. As the hook rises, the force caused by the material through the rope is pressed onto the hook body 1. The structure of the force-bearing surface of the hook body 1 and the eyelet on the lifting ring 3 at a right angle can distribute the load, causing the hook tip 6 to slightly pull the arc-shaped lever 9. This not only allows the arc-shaped lever 9 to share a small part of the force, but also improves the tightness of the connection between the hook tip 6 and the arc-shaped lever 9. Finally, when the material falls to the required position, the force applied to the hook body 1 is released, thereby opening the pull between the hook tip 6 and the arc-shaped lever 9. The user can then move the arc-shaped lever 9 to remove the rope.
