Description
Technical Field
[0001] This utility model relates to the field of hook technology, specifically a novel hook safety buckle. Background Technology
[0002] Hooks are the most common type of lifting equipment in hoisting machinery. They are usually suspended from the wire rope of the hoisting mechanism by means of pulley blocks and other components. Hooks are classified by shape as single hooks and double hooks; and by manufacturing method as forged hooks and laminated hooks. Single hooks are simple to manufacture and easy to use, but their stress distribution is not good, and they are mostly used in work applications with a lifting capacity of less than 80 tons. For large lifting capacities, double hooks with symmetrical stress distribution are often used. Laminated hooks are made of several cut and riveted steel plates. If individual plates crack, the entire hook will not be damaged, and the safety is good. However, they are heavy and are mostly used on cranes with large lifting capacities or for lifting molten steel ladles. Hooks are often subjected to impacts during operation and must be made of high-quality carbon steel with good toughness. However, the existing hook structure is simple. The object is placed inside the hook. During the hoisting process, the swing of the object may cause it to disengage, resulting in the object falling and causing safety hazards and property damage.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] Please see Figures 1-4 A novel hook safety buckle includes: a fixing plate 1, an anti-detachment component 4, and a locking component 5; a connecting block 2 is hingedly installed inside the fixing plate 1, and a hook 3 is rotatably installed inside the connecting block 2;
[0023] Please see Figure 1 , Figure 2 The anti-detachment component 4 includes a connecting protrusion 41 connected to the top of the inner side of the hook 3. A connecting pin 42 is installed inside the connecting protrusion 41. Anti-detachment buckles 43 are hinged at both ends of the connecting pin 42. Torsion springs 44 are provided on both sides of the surface of the connecting pin 42. The inner side of the anti-detachment buckle 43 is in contact with one end of the torsion spring 44. The anti-detachment buckle 43 is made of high manganese steel.
[0024] In practical use: A connecting protrusion 41 is connected to the top inner side of the hook 3. A connecting pin 42 is installed inside the connecting protrusion 41. The anti-disengagement buckle 43 is hinged to both ends of the connecting pin 42. Torsion springs 44 are provided on both sides of the surface of the connecting pin 42. The anti-disengagement buckle 43 is in contact with the torsion springs 44. Under the push of the torsion springs 44, the anti-disengagement buckle 43 contacts the inner side of the end of the hook 3, which plays a blocking role and prevents the object from swinging and falling out of the hook 3 during the hoisting process. The anti-disengagement buckle 43 is made of high manganese steel, which makes it hard and has good wear resistance.
[0025] Please see Figure 1 , Figure 3 The locking assembly 5 includes a support plate 51 fixedly connected to one side of the connecting protrusion 41. A screw 52 is threadedly connected to the surface of the support plate 51. One end of the screw 52 is connected to a buckle 53, and the other end of the screw 52 is fixedly connected to a tooth 54. A ratchet 55 is fixedly connected to one side of the anti-disengagement buckle 43, and the front end of the tooth 54 is inserted between the tooth grooves of the ratchet 55.
[0026] In practical use: A support plate 51 is connected to one side of the connecting protrusion 41. A screw 52 is threaded onto the surface of the support plate 51. A lever 53 is connected to one end of the screw 52, and a tooth 54 is connected to the other end of the screw 52. A ratchet 55 is connected to one side of the anti-disengagement buckle 43. The tooth 54 is inserted between the teeth of the ratchet 55 to limit the movement. When it is necessary to remove the attached object, pushing the lever 53 will cause the tooth 54 at the other end of the screw 52 to move out of the teeth of the ratchet 55, which will allow the anti-disengagement buckle 43 to rotate and adjust. This prevents the torsion spring 44 from being damaged and losing its push on the anti-disengagement buckle 43, causing the anti-disengagement buckle 43 to swing. This structure plays a role in locking the anti-disengagement buckle 43 during hoisting, providing double protection.
[0027] Please see Figure 4 A lever 6 is rotatably mounted in the middle of the anti-disengagement buckle 43. A release block 7 is fixedly mounted in the middle of the lever 6. The side of the release block 7 is designed with an arc-shaped protrusion. An arc-shaped fitting part 8 corresponding to the inner side of the hook 3 is opened on the surface of the release block 7. After one end of the lever 6 is rotated, it contacts and connects with the end of the hook 3.
[0028] In practical use: A lever 6 is rotatably installed in the middle of the anti-disengagement buckle 43, and a release block 7 is fixedly installed in the middle of the lever 6. The side of the release block 7 has an arc-shaped protrusion design, and the surface has an arc-shaped fitting part 8 corresponding to the inner side of the hook 3. When hanging an object, push the anti-disengagement buckle 43 towards the inside of the hook 3, pull the lever 6 so that one end contacts and supports the end of the hook 3. At this time, the release block 7 in the middle of the lever 6 rotates so that the arc-shaped fitting part 8 fits against the inner side of the hook 3. When hanging an object, the object contacts the lever 6 and drives the release block 7 to rotate. The rotation of the release block 7 causes the arc-shaped protrusion on the side to push the anti-disengagement buckle 43 away from the surface of the hook 3. At this time, the anti-disengagement buckle 43 is reset under the action of the torsion spring 44 and contacts the inner side of the end of the hook 3, which plays a limiting role. The same operation is performed when the hook is removed. When the object is taken out from the inside of the hook 3, push the lever 6 upward and the anti-disengagement buckle 43 is reset. This structure allows a single person to hang or remove the sling with both hands.
[0029] Please see Figure 4 A magnetic buckle 9 is fixedly connected to the bottom inner side of the anti-detachment buckle 43, and the magnetic buckle 9 is magnetically connected to the hook 3.
[0030] In practical use: The bottom inner side of the anti-disengagement buckle 43 is connected to a magnetic snap 9. When the anti-disengagement buckle 43 moves closer to the hook 3, the magnetic snap 9 is attracted to the inner side of the hook 3 to prevent the anti-disengagement buckle 43 from resetting. This structure is used in conjunction with the lever 6 for convenient operation.
[0031] A connecting protrusion 41 is connected to the top inner side of the hook 3. A connecting pin 42 is installed inside the connecting protrusion 41. The anti-disengagement buckle 43 is hinged to both ends of the connecting pin 42. Torsion springs 44 are provided on both sides of the surface of the connecting pin 42. The anti-disengagement buckle 43 is in contact with the torsion springs 44. Under the push of the torsion springs 44, the anti-disengagement buckle 43 contacts the inner end of the hook 3, which plays a blocking role and prevents the object from swinging and falling out of the hook 3 during the hoisting process. The anti-disengagement buckle 43 is made of high manganese steel, which makes it hard and has good wear resistance. When it is necessary to remove the hooked object, push the lever 53 to drive the insert tooth 54 at the other end of the screw 52 to move out of the tooth groove of the ratchet 55, which can make the anti-disengagement buckle 43 rotate and adjust, preventing the torsion spring 44 from being damaged and losing its push on the anti-disengagement buckle 43, which would cause the anti-disengagement buckle 43 to swing. This structure plays a role in locking the anti-disengagement buckle 43 during the hoisting process, providing double protection.
