Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lifting hooks, in particular to a lifting hook with anti-loosening function. Background Technique
[0002] A hook is the most common lifting tool in a hoisting machine. The hook is suspended on the steel wire rope of the hoisting mechanism by means of components such as pulleys, and the goods to be lifted are suspended on the hook. Many existing hooks are generally simple hook-shaped. When moving or affected by external wind force, etc., the items suspended on the hook will shake, which may cause relative displacement between the sling and the hook, resulting in the sling moving out of place, and in severe cases, it may even cause the items to fall off, posing a safety hazard.
[0003] In order to increase safety, some existing hooks are equipped with spring-type anti-disengagement clamps. However, after long-term use, the springs will deform or be lost, rendering the protection ineffective and requiring the operator to press with both hands, which is time-consuming and laborious and inconvenient to use.

Detailed implementation manners
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Embodiment 1: Please refer to Figures 1-4 , the present utility model provides a technical solution: a hook 1, a connecting seat 2 is fixedly connected to the surface of the hook 1, a mounting frame 7 is fixedly connected to the hook 1, and a loosening prevention assembly 9 is arranged on the mounting frame 7; the loosening prevention assembly 9 includes a loosening prevention frame 901, the loosening prevention frame 901 is rotatably connected to the connecting seat 2, a loosening prevention rod 902 is rotatably connected to one side of the loosening prevention frame 901, a connecting frame 903 is fixedly connected to the surface of the loosening prevention frame 901, a rotating rod 909 is fixedly connected to one side of the connecting frame 903, a chute 904 is opened on one side of the mounting frame 7, a slider 905 is slidably connected in the chute 904, a connecting plate 906 is fixedly connected to one side of the slider 905, a second connecting seat 907 is rotatably connected to the connecting plate 906, a through hole 908 is opened on the second connecting seat 907, the second connecting seat 907 is rotatably connected in the through hole 908, a lead screw 910 is rotatably connected in the chute 904, the lead screw 910 is threadedly connected to the slider 905, and a turntable 911 is fixedly connected to the top of the lead screw 910. An anti-slip groove is opened inside the hook 1.
[0023] Analysis of the above content: Rotate the rotating rod 912 to drive the turntable 911 to rotate, so that the lead screw 910 rotates. Under the action of the lead screw 910, the slider 905 moves up and down along the chute 904. The movement of the slider 905 drives the rotating rod 909 to move up and down, so that the connecting frame 903 and the loosening prevention rod 902 rotate along the connecting seat 2, so that the loosening prevention frame 901 moves towards the inside of the hook 1. Hang the item to be hoisted in the hook 1, and rotate the rotating rod 912 in the reverse direction to make the loosening prevention frame 901 move towards the limiting groove 6, so that the loosening prevention rod 902 is stuck in the limiting groove 6, achieving the effect of preventing loosening and detachment.
[0024] Embodiment 2: Please refer to Figures 1-4 , the present utility model provides a technical solution based on Embodiment 1: A rotating rod 912 is rotatably connected to the turntable 911, and a limiting groove 6 matching the loosening prevention rod 902 is opened on the surface of the hook 1.
[0025] Analysis of the above content: Through the mutual cooperation of the loosening prevention rod 902 and the limiting groove 6, the loosening prevention frame 901 will not move easily, further improving the effect of preventing loosening and detachment. By rotating the rotating rod 912 to drive the turntable 911 to rotate, the rotation speed of the turntable 911 is increased.
[0026] Example 3: Please refer to Figures 1-4 , the present utility model provides a technical solution based on Example 1: A fillet 5 is provided on the surface of the hook 1, a threaded rod 3 is threadedly connected to the upper surface of the connecting seat 2, and a limiting block 4 is fixedly connected to the surface of the threaded rod 3.
[0027] Analysis of the above content: The limiting block 4 is used to facilitate the connection between the hook 1 and the steel wire rope, and a threaded hole matching the threaded rod 3 is provided in the connecting seat 2.
[0028] Example 4: Please refer to Figures 1-4 , the present utility model provides a technical solution based on Example 1: An anti-misoperation component 8 is provided on the hook 1. The anti-misoperation component 8 includes a limiting hole 801 opened on the turntable 911, a positioning groove 802 is opened on one side of the mounting bracket 7, a sliding block 803 is slidably connected in the positioning groove 802, a limiting rod 804 is fixedly connected to the top of the sliding block 803, a mounting block 806 is fixedly connected to the surface of the mounting bracket 7, and a spring 805 is fixedly connected to the top of the mounting block 806.
[0029] Analysis of the above content: Without external force, the limiting rod 804 moves upward under the action of the spring 805, so that the limiting rod 804 extends into the limiting hole 801 to lock the position of the turntable 911 and prevent the turntable 911 from rotating, achieving the anti-misoperation effect. When the turntable 911 needs to be rotated, the sliding block 803 is pressed downward to compress the spring 805, so that the limiting rod 804 moves downward and disengages from the lock of the limiting hole 801. At this time, the turntable 911 can be rotated to facilitate hanging the rope.
[0030] Example 5: Please refer to Figures 1-4 , the present utility model provides a technical solution based on Example 1: One end of the spring 805 is fixedly connected to the bottom of the sliding block 803, and the limiting rod 804 is slidably connected in the limiting hole 801.
[0031] Analysis of the above content: Under the action of the spring 805, the limiting rod 804 always extends into the limiting hole 801 without external force to limit the position of the turntable 911 and prevent the turntable 911 from rotating due to misoperation.
[0032] Example 6: Please refer to Figures 1-4 , the present utility model provides a technical solution based on Example 1: The mounting bracket 7 is arranged at the central position on the surface of the hook 1, and the through hole 908 is arranged at the central position on the surface of the rotating rod 909.
[0033] Analysis of the above content: The rotating rod 909 is driven to move through the through hole 908 to ensure that the two connecting brackets 903 are subjected to the same force and ensure the stability of the movement.
