Description

Technical Field

[0001] This utility model relates to a universal swivel lifting ring, specifically a damped universal swivel lifting ring. Background Technology

[0002] A swivel lifting ring is a tool specifically designed for lifting applications involving angles. It can rotate 360 ​​degrees horizontally and flip 180 degrees vertically, offering a safety factor four times greater in any direction. Due to its greater flexibility during lifting and its ability to meet various lifting needs, the swivel lifting ring has been widely adopted.

[0003] For example, a patented universal rotating lifting ring (publication number CN214733864U) can achieve longitudinal rotation and lateral flipping with high flexibility. However, when lifting such a ring, because the ring body is in a flexible and flipping state, workers need to support it from both sides to keep it upright before it can be lifted smoothly. However, in some areas with narrow spaces, it is difficult for workers to provide effective support, which increases the difficulty of lifting. In addition, the freely moving ring body is prone to bumping into the surface of the object being lifted when flipping, causing surface damage. Utility Model Content

[0004] The purpose of this invention is to provide a damped universal rotating lifting ring. By optimizing the structure of the existing lifting ring and adding a damping structure, the lifting ring body can be kept in a vertical state, or a damping force can be provided when the lifting ring body is flipped.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a damping universal rotating lifting ring, comprising a U-shaped lifting ring body, a rotating load-bearing block, a sleeve, and bolts. The U-shaped lifting ring body has integrally formed assembly rings at both ends. The rotating load-bearing block is a sleeve structure with a through mounting hole in the center and a pair of connecting shafts extending outwards. The connecting shafts are inserted into the assembly rings and, in conjunction with retaining rings, assemble the rotating load-bearing block with the U-shaped lifting ring body. The sleeve is placed in the mounting hole of the rotating load-bearing block, and the bolts are inserted into the sleeve. The characteristic feature is that an elastic damping element is sleeved on the connecting shaft between the assembly ring and the rotating load-bearing block.

[0006] Preferably, the elastic damping element is a wave spring or a snap ring.

[0007] Preferably, the lower end of the sleeve is integrally formed with a washer, the upper inner wall is provided with an annular groove, the lower surface of the bolt is provided with an external thread, and the upper side wall is provided with an annular protrusion, and the annular protrusion and the annular groove on the inner wall of the sleeve are used to achieve an interference fit.

[0008] Preferably, the upper end of the bolt has a bolt head, the upper surface of the bolt head is provided with an internal hexagonal groove, and the side wall of the bolt head is provided with knurling.

[0009] Preferably, the upper end of the bolt has a bolt head, which has an internal and external hexagonal structure.

[0010] Preferably, the inner side of the assembly ring is provided with a C-angle, and the connection between the connecting shaft and the rotating load block is transitioned by an arc-shaped unloading groove, and the arc-shaped unloading groove is matched with the C-angle of the inner side of the assembly ring.

[0011] Preferably, the outer surface of the assembly ring is provided with a C-angle, and after the connecting shaft is inserted, the retaining ring at the end is located inside the C-angle.

[0012] Preferably, the length of the sleeve is the same as the length of the mounting hole.

[0013] Compared with the prior art, the damped universal swivel lifting ring disclosed in this utility model has the following beneficial effects: By setting an elastic damping element between the assembly ring and the rotating load-bearing block, the position of the U-shaped lifting ring can be limited, so that it can remain vertical when needed, which is convenient for lifting. It can also provide lateral damping force when the U-shaped lifting ring flips, so as to prevent the lifting ring from flipping directly due to excessive weight and hitting the product surface.

Detailed Implementation

[0015] 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. Example

[0016] like Figure 1-2As shown, this utility model provides a damping type universal rotating lifting ring, including a U-shaped lifting ring body 1, a rotating counterweight 2, a bolt 3, a sleeve 4, and an elastic damping element 5. The U-shaped lifting ring body has assembly rings 11 integrally formed at both ends. The rotating counterweight is a sleeve structure with a through mounting hole 21 in the center and a pair of connecting shafts 22 extending outward. The connecting shafts are inserted into the assembly rings and cooperate with the retaining rings 23 to realize the assembly of the rotating counterweight and the U-shaped lifting ring body. The elastic damping element is fitted on the connecting shafts and located between the assembly ring and the rotating counterweight. The elastic damping element provides damping force when the U-shaped lifting ring body rotates. The sleeve is placed in the mounting hole of the rotating counterweight, and the bolt is inserted into the sleeve.

[0017] Specifically, the assembly ring has an assembly hole in the middle, and both sides of the assembly hole are provided with C-angle 12. The C-angle on the outside of the assembly hole ensures that the retaining ring is located inside the C-angle after assembly, which can prevent the retaining ring from being damaged or falling off due to external collisions during use.

[0018] The connecting shaft of the rotating counterweight is inserted into the assembly ring, and the connection between the connecting shaft and the rotating load-bearing block is transitioned by an arc-shaped unloading groove. After assembly, the arc-shaped unloading groove and the C-angle on the inner side of the assembly ring cooperate to achieve curved surface contact.

[0019] The elastic damping element is used to provide damping force when the assembly ring rotates relative to the rotating counterweight. The specific elastic damping element can have various structural forms, such as wave spring, snap ring or other non-flat elastic sheet structure, but in this embodiment, wave spring is preferred.

[0020] The sleeve is inserted into the mounting hole, and its length is the same as the length of the mounting hole. The lower end of the sleeve is integrally formed with a retaining ring 41, and the upper end face of the inner wall of the sleeve is provided with an annular groove.

[0021] The bolt is an internal hexagon bolt with an internal hexagonal groove on the upper surface of the bolt head and knurling 31 on the side wall of the bolt head. The lower end surface of the bolt has external threads 32, and the upper end surface has an annular protrusion 33. The annular protrusion has a flat section and a beveled section, wherein the inclination angle of the beveled section is 8~9°. During assembly, the bolt is inserted into the sleeve, and the annular protrusion enters the annular groove of the sleeve through the beveled section, realizing an interference fit between the two. Example

[0022] like Figures 3-4 As shown, compared with the first embodiment, the bolt structure is replaced in this embodiment, and an internal and external hexagonal bolt is selected. The bolt head has a combination of internal and external hexagonal structures. The lower end surface of the rod has external threads, and the upper end surface of the rod has an annular protrusion. The annular protrusion cooperates with the annular groove of the sleeve to achieve a solid assembly of the two.

[0023] The damping universal rotating lifting ring of this utility model can limit the position of the U-shaped lifting ring by setting an elastic damping element between the assembly ring and the rotating load-bearing block, so that it can remain vertical when needed, which is convenient for lifting. It can also provide lateral damping force when the U-shaped lifting ring flips, so as to prevent the lifting ring from directly flipping over due to excessive weight and hitting the product surface.

[0024] 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.
