Description

Technical Field

[0001] The utility model relates to the technical field of mechanical connectors, in particular to a lifting ring. Background Art

[0002] Lifting rings are a common lifting accessory, mainly used for lifting and carrying heavy objects. They are usually made of metal forging or casting, designed to withstand great tension and ensure the safety of lifting operations.

[0003] There are many types of lifting rings according to usage requirements, including: rotating lifting rings, standard lifting rings, lifting rings with stops, etc. For example, the rotating lifting ring has a structure with a rotating function to facilitate the rotation of the lifting object during the lifting process. However, in the lifting process, there are often many working conditions where the tool used to connect the lifting ring is a long rope instead of a hook; when this phenomenon occurs, if you want to separate the rope, the lifting ring and the weight, you need to first turn the bolt to separate the pull ring and the weight, and then pull the rope until the entire rope leaves the inner hole of the pull ring. This method is cumbersome and labor-intensive, and in many lifting conditions, since the rope is connected to other lifting equipment, if you want to find one end of the rope to disengage it from the inner hole of the lifting ring, you often need to disengage the rope from the lifting equipment, which greatly increases the complexity of the operation. Utility Model Content

[0004] The utility model aims to provide a lifting ring, which can be easily disassembled and assembled, thereby reducing the complexity of operation and workload and improving lifting efficiency.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a lifting ring, comprising a pull ring with an inner hole and a bolt connected to a weight, the pull ring comprising a ring body and a ring seat, the inner hole is formed between the ring body and the ring seat, a rotating hole for the bolt to pass through is formed on the ring seat, the bolt and the rotating hole are rotatably matched and restrict the two from moving away from each other, a locking assembly that cooperates with the pull ring is provided on the ring seat, the locking assembly has a locking state that fixes the pull ring and the ring seat and an unlocking state that separates the two, a linkage assembly for controlling the locking assembly is provided between the bolt and the locking assembly, when the bolt is located in the rotating hole, the bolt controls the locking assembly to be in a locked state through the linkage assembly; when the bolt leaves the rotating hole, the bolt controls the locking assembly to be in an unlocked state through the linkage assembly.

[0006] By adopting the above technical solution, the ring body and the ring seat are positioned to the matching position, and then the bolt is passed through the rotating hole to be threadedly connected with the weight. During the threaded connection process, the bolt drives the ring seat to move toward the weight and allows the bolt head to gradually enter the rotating hole. After the bolt head enters the rotating hole, the ring seat and the ring body are locked by the provided linkage assembly and the locking assembly, thereby forming a stable inner hole structure. When the rope, the lifting ring and the weight are to be separated, the locking assembly can be unlocked by loosening the bolt and leaving the rotating hole, and the lifting ring and the weight, and the lifting ring and the rope are separated synchronously, so as to achieve the purpose of convenient disassembly and assembly, reduce the cumbersomeness of operation and workload, and improve lifting efficiency.

[0007] It is further configured that the locking assembly includes at least two sliding holes opened in the ring seat and connected to the outside at one end and connected to the rotating hole at the other end, a locking rod slidably set in each sliding hole, and a locking hole opened in the ring body and for the locking rod to be inserted.

[0008] By adopting the above technical solution, the locking rod reciprocates in the sliding hole toward one side of the locking hole. When the locking rod enters the locking hole, it is in a locked state, and when it leaves the locking hole, it is in an unlocked state.

[0009] It is further configured that: the linkage assembly includes a driving bevel formed on the bolt head, a matching bevel formed on each locking rod and cooperating with the driving bevel for driving the locking rod to move relative to the rotating hole, and a reset spring connecting each locking rod, the driving bevel is arranged around the outer periphery of the bolt head to form a ring, and when the bolt is located in the rotating hole, the locking rod is driven to be synchronously located in the locking hole and the sliding hole.

[0010] By adopting the above technical solution, the bolt head drives the driving bevel to enter the rotating hole and exerts a force on the matching bevel. The direction of the force is changed by the cooperation between the driving bevel and the matching bevel, thereby driving the locking rod to move toward one side of the lock hole, thereby achieving the purpose of linkage locking.

[0011] It is further configured that: the locking rod is in a polygonal column shape, and the cross-sectional shape of the sliding hole is adapted to the shape of the locking rod.

[0012] By adopting the above technical solution and the above structure, the circumferential rotation of the locking rod in the sliding hole is avoided, so as to ensure that the driving inclined surface can form a precise and stable fit with the matching inclined surface, thereby ensuring the reliability of the structure.

[0013] It is further configured that: the locking rod is rotationally matched with the locking hole.

[0014] By adopting the above technical solution and the above structure, the rotational cooperation between the ring body and the ring seat is achieved, thereby avoiding the interference of the ring body with the operation of the bolt during the rotation process, making the operation more convenient.

[0015] In summary, the utility model has the following beneficial effects: the utility model can realize convenient disassembly and assembly, thereby reducing the tediousness of operation and workload, and improving lifting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
