Technical Field
[0001] This utility model relates to the field of lifting hook technology, and in particular to a double-point magnetic self-detaching hook. Background Technology
[0002] Self-decoupling technology is a method for autonomously separating or disconnecting connections in mechanical, electrical, or automated systems. It aims to improve the safety, reliability, and efficiency of the system. With the continuous development of modern software systems, hardware systems, and complex network systems, the complexity of systems and the dependencies between modules are also increasing. This brings many challenges to the maintenance, upgrading, and expansion of the system. Self-decoupling technology has emerged in this context, aiming to improve the overall performance and scalability of the system by reducing the coupling between modules.
[0003] In scenarios such as lifting and hoisting, logistics transportation, and automated production lines, the rapid and safe unhooking of lifting devices is crucial for improving operational efficiency and ensuring safety. Traditional lifting hooks use mechanical methods, relying on manual operation or external power, which suffers from problems such as slow response speed, complex structure, and high maintenance costs. Therefore, those skilled in the art have provided a dual-point magnetic self-unhooking solution to address the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dual-point magnetic self-unhooking mechanism. In use, the load is suspended from the lower end of the hook. Gravity and the suspension force act in opposite directions, thus lifting the object. After use, pressing one end of the tail plate downwards releases the magnetic plate's attraction to the side wall, allowing free movement. Once released, the tail plate tilts to the other side under the movable connection of the tail plate and the first fixing bolt, reconnecting magnetically to the side wall of the magnetic plate, achieving rapid reset without manual intervention, facilitating future lifting operations.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-suspension-point magnetic self-unhooking mechanism, comprising two connecting plates, a lifting structure located at the upper middle part of the two connecting plates, and a reset connection structure located at the lower middle part of the two connecting plates. The reset connection structure includes a tail plate, with a hook fixedly connected to the lower end of the tail plate. A first fixing bolt is located at the lower center of the side wall of one of the connecting plates, with one end of the first fixing bolt passing through the side wall of one connecting plate, the side wall of the tail plate, and the side wall of the other connecting plate and extending to the other side. The end of the bolt is threaded with a first fixing nut. A connecting groove is provided on the side wall of the connecting plate near the tail plate, with the other side of the connecting groove penetrating the side walls of both connecting plates. A magnetic plate is connected inside the connecting groove, and the side walls of the magnetic plate are respectively connected to the connecting grooves on the side walls of the two connecting plates.
[0006] With the above technical solution, when in use, the heavy object is suspended at the lower end of the hook. The force of gravity and the force of suspension are opposite in direction, thus lifting the object. After use, by pressing one end of the tail plate downward, the side wall of the tail plate is released from the magnetic plate and can move freely. After releasing, the tail plate tilts to the other side under the movable connection of the tail plate and the first fixing bolt, and is then magnetically reconnected to the side wall of the magnetic plate, forming a quick reset without manual intervention, which is convenient for the next lifting use.
[0007] Furthermore, the lifting structure includes two lifting plates, which are jointly disposed at the upper middle part of two connecting plates. Two second fixing bolts are respectively disposed on the side wall of one of the connecting plates. The other ends of the two second fixing bolts pass through the side wall of one connecting plate, the side walls of the two lifting plates, and the side wall of the other connecting plate, and respectively lead to the other end. The ends are respectively threaded with second fixing nuts. A connecting ring is disposed at the upper end of the two lifting plates. One end of the connecting ring passes through the side wall of the two lifting plates and leads to the other side. A lifting ring is connected to the upper end of the connecting ring. A side hook is disposed on the other side of the two lifting plates. One end of the side hook passes through the side wall of the two lifting plates and leads to the other side.
[0008] With the above technical solution, when in use, the lifting is carried out by lifting rings and side hooks. The lifting position can be selected according to the actual lifting needs, and the tilting direction during overall lifting can be flexibly selected.
[0009] Furthermore, a limiting bolt is provided at the center of one side wall of the connecting plate, and the other side of the limiting bolt passes through the side walls of the two connecting plates and leads to the other side, and the end is threadedly connected to a limiting nut.
[0010] The above technical solution can restrict one side of the tailgate and prevent it from moving excessively.
[0011] Furthermore, the hook and tail plate are integrally formed structures;
[0012] The above technical solution results in a high overall strength through integral molding.
[0013] Furthermore, both lifting plates are L-shaped;
[0014] The above technical solution enables lifting from both sides, and the L-shape facilitates connection between the two sides.
[0015] Furthermore, the lower ends of both sides of the lifting ring are movably connected to the upper end surfaces of both sides of the connecting ring;
[0016] The above technical solution facilitates angle adjustment during lifting and allows for folding and storage.
[0017] This utility model has the following beneficial effects:
[0018] 1. In this utility model, the heavy object is suspended at the lower end of the hook by the reset connection structure. The force of gravity and the force of suspension are opposite to each other, so the object can be lifted. After use, by pressing one end of the tail plate downward, the side wall of the tail plate is released from the magnetic plate and can move freely. After it is released, the tail plate tilts to the other side under the movable connection of the tail plate and the first fixing bolt, and is re-magnetically connected to the side wall of the magnetic plate, forming a quick reset without manual intervention, which is convenient for the next lifting use.
[0019] 2. In this utility model, by setting up a lifting structure, the lifting is carried out by lifting rings and side hooks. The lifting position can be selected according to the actual needs of lifting, and the tilting direction during overall lifting can be flexibly selected. Attached Figure Description

The side walls of the magnetic plate 205 are respectively connected to the inside of the connecting groove 201 on the side walls of the two connecting plates 1. The heavy object is suspended at the lower end of the hook 203. Under the action of gravity and the suspension force, the object is lifted. After use, by pressing one end of the tail plate 206 downward, the side wall of the tail plate 206 is released from the magnetic plate 205 and can move freely. After it is released, under the movable connection between the tail plate 206 and the first fixing bolt 202, the tail plate 206 tilts to the other side and is magnetically connected to the side wall of the magnetic plate 205 again, forming a quick reset without manual intervention, which is convenient for the next lifting use.
[0028] The lifting structure 3 includes two lifting plates 301, which are jointly positioned at the upper middle of two connecting plates 1. Two second fixing bolts 302 are respectively installed on the side wall of one connecting plate 1. The other ends of the two second fixing bolts 302 pass through the side wall of one connecting plate 1, the side walls of the two lifting plates 301, and the side wall of the other connecting plate 1, respectively, and lead to the other end. Each end is threaded with a second fixing nut 306. A second fixing nut 306 is located at the upper end of the two lifting plates 301.
