[0002] A hook is a common component of a hoisting machine, mainly used for lifting heavy objects, and is often suspended on the steel wire rope of a hoisting mechanism through components such as a pulley block. In existing products, the anti - decoupling of the hook is achieved by using a tongue piece to hold the opening of the hook through a spring to prevent the lifting tools and ropes suspended on the hook from falling off. However, since the tongue piece is made of thin plate stamping, it is prone to extrusion deformation and damage and falling off during use. When hanging a lifting tool during operation, the tongue piece must be pressed against the spring inside to open it, and the operation is cumbersome and inconvenient. Content of the Utility Model

[0021] In order to make the above - mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific embodiments of the present utility model in conjunction with the drawings.
[0022] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art may make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings.
[0024] Please refer to Figures 1-3 As shown, this embodiment is an anti - detachment hook device for simple operation of a hook, including:
[0025] The front anti - detachment ring hook 1 has one end fixedly connected to the rear counterweight manual ring 2. Inside the connection part of the front anti - detachment ring hook 1 and the rear counterweight manual ring 2, there is a connection block 6. A hook fixing hole 5 extending to the front of the hook 4 arranged on one side is formed through the middle of the connection block 6. A pin bolt 3 is movably connected in the middle of the hook fixing hole 5;
[0026] The front anti - detachment ring hook 1 and the rear counterweight manual ring 2 are used in combination to form an anti - detachment structure to prevent the hanging object from falling off. The connection block 6, the hook fixing hole 5 and the pin bolt 3 are used in combination to install the front anti - detachment ring hook 1 and the rear counterweight manual ring 2 in a structurally movable manner;
[0027] The mass of the rear counterweight manual ring 2 is greater than that of the front anti - detachment ring hook 1, and the front anti - detachment ring hook 1 and the rear counterweight manual ring 2 form an included angle of 30°;
[0028] The different settings of the counterweight sizes are beneficial to the use of the anti - detachment structure;
[0029] The end of the pin bolt 3 is threadedly connected with a nut, and there is a clearance between the nut and the connection block 6 and the back of the hook 4;
[0030] The nut limits the end of the pin bolt 3. While satisfying the movement of the front anti - detachment ring hook 1 and the rear counterweight manual ring 2, it can prevent the structure from falling off;
[0031] Working principle: During the use of the hook 4, when using the hook 4 to lift an external object, a force can be applied to the rear counterweight manual ring 2 to make the front anti - detachment ring hook 1 move inwards under the action of the force, so that the external object can move smoothly to the inside of the hook 4. Subsequently, without applying a force, because the mass of the rear counterweight manual ring 2 is greater than that of the front anti - detachment ring hook 1, the front anti - detachment ring hook 1 can return to its original position to limit the object inside the hook 4;
[0032] In this solution, the way of using a counterweight is adopted to replace the original pressing method, which saves time and effort. Moreover, the connection method of the pin shaft bolt 3 is adopted. Compared with the original method of stamping thin plates, it can avoid the phenomenon of easy extrusion deformation, damage and falling off during use.
[0033] Please refer to Figures 1-3 As shown, on the basis of the above-mentioned Embodiment 1, this embodiment further includes a safety operation component. The safety operation component includes a magnetic attraction block 21, an operation column 22, and a wire winding column 23. One end of the operation column 22 is fixed with a wire winding column 23, and a magnetic attraction block 21 is arranged directly below the wire winding column 23;
[0034] The operation column 22 structurally fixes the wire winding column 23, which is conducive to the magnetic attraction between the energized wire winding column 23 and the magnetic attraction block 21, and can operate the rear counterweight manual ring 2 at a long distance, which helps to reduce risks;
[0035] The middle part of the operation column 22 is provided with a cavity, and a supply battery is arranged in the cavity. The output end of the supply battery is sleeved and electrically connected to the output end of the wire winding column 23;
[0036] The cavity meets the installation of the supply battery, and the supply battery is used to supply power to the wire winding column 23;
[0037] One end of the rear counterweight manual ring 2 is sleeved with a collar 24, and a limiting block 25 is fixed at the upper end of the collar 24. The inner side wall of the limiting block 25 is provided with a damping setting with the magnetic attraction block 21;
[0038] The collar 24 installs the limiting block 25, and the inner side wall of the limiting block 25 is used to structurally fix the magnetic attraction block 21 by damping;
[0039] Working principle: When the lifting hook 4 hangs an object, the operator can structurally control the operation column 22 and apply an inward pushing force to the supply battery, so that the output end of the supply battery is sleeved and extended into the input end of the wire winding column 23 to supply power to it;
[0040] Then, the energized wire winding column 23 is brought into contact with the magnetic attraction block 21, and the two are magnetically fixed, and the rear counterweight manual ring 2 can be operated at a long distance;
[0041] This solution can effectively reduce the operation risk and improve the operation safety.
[0042] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0043] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
