    Butterfly buckles and double ring buckles (also known as butterfly buckles, connecting rings, or linking rings) are mainly used to connect the chains, rings, and hooks in chain rigging. The design of this connecting ring allows for the pivot connection of a rotating ring body at each end of a connecting ring body. Its characteristic is that the body is a hollow cylindrical body, and the two rotating ring bodies are formed by a protruding embedded part at one end of a linear rod, and the other end is bent into a ring and then wound around a straight section for positioning.

    Description

    Sign

    Through this design, the two rotating rings of the double ring buckle can be placed inside the openings at both ends of the main body by convex interlocking parts, and then fixed into one by rolling and folding, so that the openings at both ends of the main body can achieve a horizontal and uniform folding effect, thereby improving the strength and flexibility of the joint and achieving better rotation effect.

    Due to its wide range of applications and importance, double ring buckles are usually made of alloy steel to ensure safety and withstand large lifting loads. This type of connecting ring is widely used in industries such as metallurgy, steel, power, ports, and domestic manufacturers of complete sets of lifting equipment and electronic hook scales. Double ring buckles can be classified into different levels according to their load-bearing capacity, such as G80 level, to meet the needs of different application scenarios. In addition, due to its unique structure and function, the double ring buckle is also known as the European style connecting double ring buckle or G80 European style double ring buckle. Together with the release buckle, it is often used to connect various hooks and chains, and is one of the key tools for lifting complete sets of rigging.

     

    The standards for butterfly buckles and double ring buckles mainly involve specifications, materials, surface treatment, and other aspects. ‌

    In terms of specifications, the specifications of butterfly buckles include specific dimensions such as workload, chain diameter, and net weight. For example, butterfly buckles of different specifications such as 1.2T, 2T, and 3.2T have different sizes and weights.

    In terms of materials, butterfly buckles and double ring buckles can be made of various materials, including carbon steel, alloy steel, stainless steel, high-strength steel, etc. The selection of these materials depends on the specific usage environment and requirements.

    In terms of surface treatment, in order to enhance the corrosion resistance and aesthetics of butterfly buckles and double ring buckles, surface treatments such as galvanizing (hot dip and electroplating), painting, Dacromet plating, etc. are usually carried out. These processing methods can effectively improve the service life and appearance quality of the product.

    In addition, the safety factor, classification (such as American and European standards), and usage location (such as marine and land use) of butterfly buckles and double ring buckles are also part of the standard. The safety factor can be 4 times, 5 times, 6 times, or even 8 times to meet different usage needs.

    In summary, the standards for butterfly buckles and double ring buckles cover multiple aspects such as specifications, materials, and surface treatment, ensuring the safety and applicability of the products and meeting the needs of different industries and application scenarios.

    Butterfly buckles and double ring buckles are mainly used to connect chains, rings, and hooks in chain rigging. ‌

    Butterfly buckle, also known as double ring buckle or connecting ring, is a type of connecting ring that is mainly connected to a rotating ring body at each end of the connecting ring body. The body of this connecting ring is a hollow cylindrical body, and the two rotating rings can be placed in the openings at both ends of the body by convex interlocking parts, and then fixed together by rolling and folding. In this way, the opening at both ends of the body can achieve a horizontal and uniform folding effect, achieving a better rotational effect that improves the strength and flexibility of the bonding force. Due to its unique structure and material, the double ring buckle is widely used in industries such as metallurgy, steel, power, ports, as well as in the manufacturing of complete sets of lifting equipment and electronic hook scales in China.

    Specifically, the uses of double ring buckles include but are not limited to:

    The connection between the chain, lifting ring, and hook in the chain rigging ensures the stability and safety of the connection.

    In the fields of construction sites, bridge engineering, electricity, etc., double ring buckles are used for connecting lifting and hoisting tools, such as connecting lifting chains with hooks to achieve lifting and hoisting of objects.

    The material of double ring buckles is usually alloy steel, which ensures safety and durability due to its high strength and excellent toughness.

    In addition, double ring buckles can be divided into European double ring buckles, national standard double ring buckles, and American double ring buckles according to different standards and purposes. These different types of double ring buckles have slight differences in design and use to meet the needs of different industries and applications.

    Overall, butterfly buckles and double ring buckles play a crucial role as important rigging accessories in various industrial and construction applications, ensuring the safety and efficiency of lifting operations.

      Structure of electric vehicle follow-up brake: It mainly includes components such as brake box, two brake shoes, crank, reset spring, adjusting parts, tension column, etc. Specifically, the working principle of the follow-up brake is to increase the rotation angle of the two brake shoes during braking through the setting of metal plates and reels, thereby increasing the maximum braking resistance. This structure achieves the adjustment of braking effect through two brake shoe blocks hinged on the hinge shaft fixed on the brake box, as well as adjusting components provided on the brake box on one side of the hinge shaft. In addition, the follow-up brake also has a lock that can lock the brake disc components, providing dust-proof and waterproof functions to ensure brake sensitivity
