[0002] Lifting slings play a crucial role in the lifting and hoisting industry; they are specialized devices designed for lifting and moving heavy objects. There are many types of lifting slings, with common ones including hooks, slings, slings, lifting suction cups, clamps, and forks. These slings are widely used in various fields such as industry and logistics to meet lifting needs in different scenarios. Hooks are among the most commonly used lifting slings, while slings are suitable for lifting packaged items.

[0003] However, when lifting certain metal parts, the hook in the existing lifting device is open at one end, which can cause the hook and the lifting ring to separate, resulting in the hook slipping or disengaging. Therefore, it does not meet the current requirements. To address this, we propose a lifting device for assembling metal parts. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting device for assembling metal parts, so as to solve the problem that when the hook in the lifting device mentioned in the background art is lifting some metal parts, the hook and the lifting ring will separate because one end of the hook is open, which leads to the hook slipping or disengaging.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for assembling metal parts, comprising a main lifting rope, a lifting frame fixedly connected to the lower end of the main lifting rope, and branch lifting ropes fixedly connected to the lower ends of the four corners of the lifting frame, with lifting rings fixedly connected to the lower ends of the branch lifting ropes, and a locking ring structure engaged at the lower end of the lifting ring, with a metal part connected to the lower end of the locking ring structure.

[0006] Preferably, the snap-fit ​​ring structure includes a semi-circular snap-fit ​​ring that snaps into the lower end of the snap-fit ​​ring. The semi-circular snap-fit ​​ring has an inner groove inside, and side grooves are provided on both the front and rear sides of the inner groove.

[0007] Preferably, the lower end of the semi-annular lifting ring is provided with a threaded post, and the four corners of the upper end face of the metal part are provided with threaded holes, and the threaded post at the lower end of the semi-annular lifting ring is connected to the threaded hole.

[0008] Preferably, the closed structure includes a curved spring connected inside the inner groove, one end of the curved spring is connected to a movable column, and movable protrusions are fixedly connected to both sides of the movable column.

[0009] Preferably, the cross-sections of the movable column and the inner groove are both designed as curved structures, the curvature of the movable column is the same as that of the inner groove, the movable column moves within the inner groove, and the movable protrusion moves within the side groove.

[0010] Preferably, the hanger is divided into four connecting frames, and connecting columns are fixedly connected between the four connecting frames.

[0011] Preferably, the lower end of the inner ring surface of the semi-annular lifting ring is provided with a groove, and the lifting ring is embedded in the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model has a groove at the lower end of the inner ring surface of the semi-circular lifting ring. The lifting ring is embedded in the groove. When the entire lifting ring is snapped into the inner ring of the snap ring structure, the inner ring surface of the lifting ring fits into the groove. The groove makes the lifting ring stable in the inner ring of the semi-circular lifting ring, thus making the entire lifting ring less likely to slip off.

[0014] 2. In this utility model, the movable column compresses the curved spring inside the inner groove, causing the movable column to move continuously into the inner groove. At this time, the overall locking ring structure is in the open state. Then, the overall lifting ring is inserted into the inner side of the movable column, so that the overall lifting ring is locked in the closed structure. The overall locking ring structure replaces the existing lifting ring, and the lifting ring replaces the existing hook. The locking fit between the lifting ring and the locking ring structure makes it difficult for them to slip or disengage. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 An embodiment of this utility model provides a lifting device for assembling metal parts, including a main lifting rope 1, a lifting frame 2 fixedly connected to the lower end of the main lifting rope 1, and a branch lifting rope 4 fixedly connected to the lower end of each of the four corners of the lifting frame 2. A lifting ring 5 is fixedly connected to the lower end of the branch lifting rope 4, and a snap-fit ​​ring structure 6 is engaged at the lower end of the lifting ring 5. A metal part 7 is connected to the lower end of the snap-fit ​​ring structure 6.

[0022] The snap ring structure 6 includes a semi-circular lifting ring 601 snapped into the lower end of the lifting ring 5. The semi-circular lifting ring 601 has an inner groove 603 inside, and side grooves 602 are provided on both the front and rear sides of the inner groove 603.

[0023] A threaded post is provided at the lower end of the semi-annular lifting ring 601, and threaded holes 9 are provided at the four corners of the upper end face of the metal part 7. The threaded post at the lower end of the semi-annular lifting ring 601 is connected to the threaded hole 9, so the overall snap ring structure 6 can be connected to the threaded hole 9 at the upper end of the metal part 7 through the threaded post at the lower end, thereby realizing the connection between the metal part 7 and the snap ring structure 6.

[0024] The aforementioned closed structure 8 includes a curved spring 803 connected inside the inner groove 603. One end of the curved spring 803 is connected to a movable column 801. Movable protrusions 802 are fixedly connected to both sides of the movable column 801. The cross-sections of the movable column 801 and the inner groove 603 are both designed as curved structures. The curvature of the movable column 801 is the same as that of the inner groove 603. This arrangement allows the movable column 801 to move within the inner groove 603, while the movable protrusions 802 can move within the side groove 602. The curved spring 803 provides a stretching elastic force to the movable column 801.

[0025] The lower end of the inner ring surface of the semi-circular lifting ring 601 is provided with a groove 604, and the lifting ring 5 is embedded in the groove 604. When the entire lifting ring 5 is engaged in the inner ring of the engaging ring structure 6, the inner ring surface of the lifting ring 5 is in contact with the groove 604. The setting of the groove 604 enables the lifting ring 5 to be stably placed in the inner ring of the semi-circular lifting ring 601, thereby making the entire lifting ring 5 less likely to slip off.

[0026] In use, by pressing the movable protrusion 802 in the closed structure 8, the movable protrusion 802 causes the movable column 801 to bend and move into the inner groove 603. The movable protrusion 802 moves along the side groove 602, while the movable column 801 moves along the inner groove 603. This operation causes the movable column 801 to squeeze the curved spring 803 inside the inner groove 603, thereby causing the movable column 801 to move continuously into the inner groove 603. At this time, the overall snap-fit ​​ring structure 6 is in the open state. Then, the overall lifting ring 5 is snapped into the inside of the movable column 801, so that the overall lifting ring 5 is snapped into the closed structure 8.

[0027] The integral snap-fit ​​ring structure 6 replaces the existing lifting ring, and the lifting ring 5 replaces the existing lifting hook. The snap-fit ​​ring structure 6 and the lifting ring 5 are interlocked, making it less likely for them to slip or come off.

[0028] If the entire lifting ring 5 is to be disassembled, press the movable protrusion 802 on the outside of the movable column 801 again, so that the movable column 801 slides into the inner groove 603, thereby causing the two movable columns 801 to move into the inner groove 603 again. This operation makes the two movable columns 801 open, and the lifting ring 5 inside the lifting ring 5 can be disassembled, thereby realizing the separation of the lifting ring 5 and the overall snap-fit ​​ring structure 6.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
