Description

Technical Field

[0001] The utility model relates to a lifting ring, in particular to a side-pulling lifting ring. Background Art

[0002] A swivel lifting ring, also known as a universal lifting ring or a swivel lifting ring screw, is used in hoisting occasions with two or more lifting points and can achieve 360° horizontal rotation and 180° up-and-down flipping. At present, the swivel lifting rings on the market have relatively poor stress performance during side-hoisting and cannot well meet the high-load and safe use requirements of users.

[0003] As a type of swivel lifting ring, the side-pulling lifting ring has its lifting ring located on one side of the bolt. Therefore, it is an important connecting piece indispensable in the hoisting process of many products or objects. When the existing side-pulling lifting ring is actually used, when the lifting ring unloads force during hoisting, due to the relatively large inertial force on the rotating lifting ring, a rotating direction will be generated. The rotating lifting ring will collide with surrounding objects or load-bearing blocks, and may cause the load-bearing block itself to rotate. At the same time, the rotation flexibility of the bolt of the existing side-pulling lifting ring is poor, and it is prone to jamming problems during rotation. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a side-pulling lifting ring, optimize the structure of the bolt assembly part, improve the rotation flexibility, and ensure the safety factor.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A side-pulling lifting ring, comprising a lifting ring, a load-bearing block, a bushing, a bolt and an elastic member. A vertically penetrating installation hole is provided on one side of the load-bearing block. The bolt is inserted into the installation hole in cooperation with the bushing. On the other side of the load-bearing block, there is a horizontally penetrating assembly hole for assembling the lifting ring. The assembly hole is perpendicular to the installation hole, and there is a through notch for assembling the elastic member between them. The elastic member is of type B, with its flat surface facing the installation hole and abutting against the outer wall of the bushing, and its curled surface facing the assembly hole and abutting against the lifting ring.

[0006] Preferably, the bushing includes an upper bushing and a lower bushing that are butt-jointed, and retaining rings are integrally formed at the upper end of the upper bushing and the lower end of the lower bushing.

[0007] Preferably, the lower end of the upper bushing extends with an assembly step surface with a reduced outer diameter, and the upper end of the lower bushing extends with a sleeve that mates with the assembly step surface, and a Z-shaped assembly is formed between the assembly step surface of the upper bushing and the sleeve of the lower bushing.

[0008] Preferably, the bolt includes a bolt head and a screw rod. The upper part of the screw rod is a smooth rod structure, and the lower part is provided with an external thread. There is an annular protrusion between the external thread and the smooth rod structure, and the outer diameter of the annular protrusion is greater than the inner diameter of the bushing.

[0009] Preferably, an annular groove for accommodating the annular protrusion is provided on the inner wall of the lower bushing.

[0010] Preferably, the lifting ring is an O-shaped lifting ring.

[0011] Compared with the prior art, a side-pulling lifting ring disclosed by the present utility model has the following beneficial effects:

[0012] By adopting a bushing structure with upper and lower docking and cooperating with the annular protrusion on the surface of the bolt, the stability after assembly can be ensured. At the same time, a rotational fit is formed between the annular protrusion and the annular groove of the lower bushing, improving the rotational flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 is an exploded view of an embodiment of the present utility model;

[0015] Figure 3 is Figure 1 a partial enlarged view in DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] As Figures 1-3 shown, a side-pulling lifting ring provided by the present utility model includes a lifting ring 1, a load-bearing block 2, an upper bushing 3, a lower bushing 4, a bolt 5 and an elastic member 6. A vertically penetrating mounting hole 21 is provided on one side of the load-bearing block, and a horizontally penetrating assembly hole 22 is provided on the other side. The upper bushing and the lower bushing are respectively inserted and docked from both sides of the mounting hole, and the bolt is inserted through the docked upper bushing and lower bushing. The lifting ring is O-shaped and is assembled in the assembly hole.

[0018] Specifically, the mounting hole and the assembly hole are perpendicularly arranged, not communicating with each other but provided with a penetrating notch 23. The mounting hole is used for inserting the bolt, and the assembly hole is used for installing the lifting ring. The dislocation between the two forms sideward lifting.

[0019] The upper bushing and the lower bushing are matched with each other. Retaining rings 7 are integrally formed at the upper end of the upper bushing and the lower end of the lower bushing. In order to ensure the fastening degree of the mutual butt joint, an assembly step surface 31 with a reduced outer diameter extends from the lower end of the upper bushing, and a sleeve 41 that matches the assembly step surface extends from the upper end of the lower bushing. The assembly step surface of the upper bushing and the sleeve of the lower bushing form a Z-shaped assembly after butt joint, which can ensure the fastening of the assembly.

[0020] The bolt includes a bolt head 51 and a screw rod 52. The upper part of the screw rod is a smooth rod structure, and the lower part is provided with an external thread 53. An annular protrusion 54 is provided between the external thread and the smooth rod structure, and the outer diameter of the annular protrusion is slightly larger than the inner diameter of the bushing. The setting of the annular protrusion enables the bolt to extrude the butt joint of the upper bushing and the lower bushing when inserted into the upper bushing and the lower bushing, causing it to deform and expand outward so as to abut against the inner wall of the mounting hole, forming an integral body with the load-bearing block to ensure the safety factor of the whole. At the same time, in order to improve the rotational flexibility of the bolt, an annular groove 42 is provided on the inner wall of the lower bushing, so that the annular protrusion is located in the annular groove after the bolt is assembled in place, thus not affecting the rotational flexibility.

[0021] The elastic member is of type B. It is assembled in the notch 23, and the plane of the elastic member faces the mounting hole and abuts against the outer wall of the bushing, and the curled surface faces the assembly hole and abuts against the suspension ring.

[0022] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
