Description

Technical Field

[0001] This utility model relates to the field of lifting hook technology, and in particular to an automatic return safety anti-detachment clip. Background Technology

[0002] Lifting equipment is a key piece of equipment widely used in industrial handling, logistics loading and unloading, and construction. It is mainly used for lifting and moving heavy objects. Traditional lifting equipment is usually made of metal structure and relies on mechanical force or hydraulic system to lift and move the load. With the development of industrial automation, the design of lifting equipment is gradually evolving towards lightweight, intelligent and high safety.

[0003] However, existing lifting devices still have some shortcomings and areas for improvement in actual use. Existing lifting devices usually require manual assistance during lifting, and cannot achieve automatic suspension and lifting. At the same time, existing lifting devices cannot adjust the movement space between hooks according to the structure of the lifting. Therefore, those skilled in the art have provided an automatic return safety anti-detachment device to solve 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 an automatic return safety anti-detachment clip. The clip works by placing the workpiece or the steel cable to be lifted downwards along a groove. During placement, two connecting teeth are pressed downwards. Under the action of the connecting shaft, the connection between the load-bearing plate and the two connecting teeth is similar to a seesaw. When the workpiece or the steel cable to be lifted is placed inside the groove, the load-bearing plate, relying on its own weight, quickly resets the two connecting teeth, thus completing the lifting process and achieving an anti-detachment effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic return safety anti-detachment clip, comprising a main body, a groove provided at the center of one side wall of the main body, the groove penetrating the side wall of the main body and connecting to the other side, a load-bearing plate provided at the front side of the main body, connecting teeth fixedly connected to the rear side walls of the load-bearing plate on both sides, the load-bearing plate being connected to the front side wall of the main body through a movable structure, and a limit structure provided at the center of the two side walls of the main body at the upper end of the two connecting teeth;

[0006] The movable structure includes a lower pressure sleeve, the lower end of which is fixedly connected to the front side wall of the main body. The upper end of the lower pressure sleeve is hinged to an upper pressure sleeve. Fixed connecting plates are fixedly connected to the front side walls of the upper and lower pressure sleeves respectively. Fixed screws are symmetrically arranged on the upper end surface of the fixed connecting plate at the front end of the upper pressure sleeve. The lower ends of the two fixed screws pass through the two fixed connecting plates and lead to the lower end respectively, and the ends are threaded with fixed nuts.

[0007] With the above technical solution, when in use, the workpiece or the steel cable to be lifted is placed downward along the groove. During the placement process, the two connecting teeth are pressed downward. Under the action of the connecting shaft, the connection between the load plate and the two connecting teeth is similar to a seesaw. When the workpiece or the steel cable to be lifted is placed into the inside of the groove, the load plate quickly resets the two connecting teeth by its own weight, so that the whole thing is lifted and the effect of preventing it from falling off can be achieved.

[0008] Furthermore, the limiting structure includes a vertical groove, which is located at the center of one side wall of the main body. A plurality of positioning screw holes are provided at the center of one inner side wall of the vertical groove. A movable slide plate is slidably connected inside the vertical groove. A pressure plate is fixedly connected to the lower end of the center of one side wall of the movable slide plate. A positioning bolt is provided at the center of one side wall of the movable slide plate. The positioning bolt passes through the side wall of the movable slide plate and extends to the other side, and its end is threaded into the inside of the positioning screw hole.

[0009] With the above technical solution, during use, the position of the movable sliding plate and the pressure plate in the vertical groove can be adjusted according to the needs of hoisting. The lower end of the pressure plate presses against the upper surface of the connecting teeth through the cooperation between the positioning bolts and the positioning screw holes, thereby limiting the upward angle of the connecting teeth.

[0010] Furthermore, a connecting hole is provided on the front side wall of the main body near the rear side of the upper pressure sleeve, and a connecting strong magnet is provided inside the connecting hole;

[0011] With the above technical solution, when in use, the upper and lower pressure sleeves can be opened, and the rear side wall of the upper pressure sleeve can be magnetically connected to the connecting strong magnet, thereby facilitating the removal of the connecting shaft and the load-bearing plate.

[0012] Furthermore, a connecting shaft is provided between the upper and lower pressure sleeves, and the lower ends of both sides of the connecting shaft are respectively fixedly connected to the front sidewall of the load-bearing plate.

[0013] The above technical solution connects the load-bearing plate to the connecting shaft, and the connecting shaft rotates inside the upper and lower pressure sleeves, thereby enabling the load-bearing plate to automatically reset after use.

[0014] Furthermore, the load-bearing plate and the two connecting teeth are integrally formed;

[0015] The above technical solutions result in a more stable one-piece molded structure.

[0016] Furthermore, the load-bearing plate is C-shaped;

[0017] Through the above technical solution, the C-shape is easy to adapt to the front side wall of the main body, and can provide a certain amount of activity space and limiting distance.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, by setting up a movable structure, the workpiece or the steel cable to be lifted is placed downward along the groove. During the placement process, the two connecting teeth are pressed downward. Under the action of the connecting shaft, the connection relationship between the load plate and the two connecting teeth is similar to a seesaw. When the workpiece or the steel cable to be lifted is placed into the inside of the groove, the load plate quickly resets the two connecting teeth by its own weight, so that the whole is lifted and the effect of preventing falling off can be achieved.

[0020] 2. In this utility model, by setting a limiting structure, the position of the movable sliding plate and the pressure plate in the vertical groove can be adjusted according to the needs of hoisting. The lower end of the pressure plate presses against the upper end surface of the connecting tooth through the cooperation between the positioning bolt and the positioning screw hole, thereby limiting the upward angle of the connecting tooth.

[0021] 3. In this utility model, by setting an movable structure, the upper pressure sleeve and the lower pressure sleeve are opened, and the rear side wall of the upper pressure sleeve is magnetically connected to the connecting strong magnet, so that the connecting shaft and the load plate can be removed, making it usable as an ordinary hook, which is convenient for assembly and use and more flexible.
