[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 As shown, the present invention provides a sleeve-type ball bearing lifting ring, including a lifting ring 1, a rotating connector 2, a fixed connecting seat 3, multiple balls 4, and a press-fit sealing component 5. The rotating connector is assembled with the balls in the fixed connecting seat, allowing it to rotate relative to the fixed connecting seat. The lifting ring is assembled with the rotating connector to achieve lifting. The fixed connecting seat has an internally threaded sleeve structure below it to achieve connection with the object being lifted.

[0025] Specifically, the lifting ring has an elliptical structure, and the rotating connector has a base 21. A connecting lug 22 for assembling the lifting ring is integrally formed on the upper part of the base, and a rotating shaft 23 is integrally formed on the lower part of the base. An arc-shaped groove 24 for accommodating balls is provided on the side wall of the rotating shaft. When the lifting ring is in a vertical state, the central axis of the lifting ring overlaps with the central axis of the rotating shaft.

[0026] The connecting fixing base structure is as follows Figure 2 As shown, the assembly section 31 and the connecting section 32 are located at the top. The assembly section has an external hexagonal structure and an internal assembly groove 33. The inner wall of the assembly groove has a second annular groove 34. The second annular groove and the annular groove on the side wall of the rotating shaft form a support for both sides of the ball bearing, thus forming a bearing structure. The side wall of the fixed connecting seat has an insertion hole 35 that connects to the second annular groove, and the inner wall of the insertion hole has an annular pressing groove 36. During assembly, the ball bearing is fed into the space between the second annular groove and the annular groove through the insertion hole. The connecting section is a sleeve structure with an internal thread 37, which enables the lifting of the screw on the product.

[0027] The press-fit sealing component is embedded in the insertion hole and includes a limiting block 51 and a plug 52. The limiting block is placed at the front end of the insertion hole, and the plug is placed at the rear end of the insertion hole outside the limiting block. One end face of the plug is a planar structure, and the other end face has a press-fit edge 53 extending around it. After assembly, the press-fit edge is pressed into the annular press-fit groove.

[0028] The fixed connecting seat of the conventional lifting ring is fixed. When it is used for lifting with the screw, the sleeve structure of this utility model is used. When it is used for lifting with the threaded hole, the conventional screw structure is used. When lifting multiple different types of products, the lifting ring needs to be changed frequently, which is very cumbersome.

[0029] Therefore, this utility model also includes an adapter 6, which has various structural forms, such as... Figure 3 The adapter shown has screw structures at both ends. The screw at one end is screwed into the internal thread of the fixed connecting seat, and the screw at the other end can be used for hoisting with conventional threaded hole structures. Furthermore, by setting different outer diameters of the screws at both ends, it can also meet the hoisting requirements of different opening sizes on different products without the need to replace the entire lifting ring.

[0030] like Figure 4 The diagram shows another type of adapter structure, with one end being a screw structure 61 and the other end being an internally threaded sleeve structure 62. This adapter can be used when the lifting distance needs to be extended. At the same time, by setting the outer diameter of the screw and the inner diameter of the internally threaded sleeve to match the lifting of different sizes of screws on the product, the ease of use is greatly improved.

[0031] The sleeve-type ball bearing lifting ring disclosed in this utility model can meet the lifting requirements of screw type by setting an internal threaded sleeve structure at the bottom. Furthermore, by adding an adapter, the lifting ring can meet the lifting requirements of different structures and sizes, which not only improves the overall adaptability and versatility and reduces costs, but also increases the lifting load coefficient and improves safety performance through the double-layer structure.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
