Mining open connection ring, also known as horseshoe ring or horseshoe buckle, is suitable for double scraper conveyor and transfer machine under the coal mine shaft, which is connected with mine high strength round link chain and scraper. The standard of mining connecting ring is open link for mining ring chain (MT / T 71-1997)

Mining open connection ring can be installed horizontally and vertically when it is used. It is suitable for comprehensive mining scraper conveyor, 630, 730 and other types of scraper conveyor, and it is used to connect scraper and chain. Due to the novel and unique design of connecting ring, its overall dimension is the same as the ring chain, and it is not limited by the installation direction and occasion.

1. The main body is a hollow cylinder, the two rotating rings form a convex large inlay part from one end of the first line rod, and the other end bends the ring and then circles it on the straight section for positioning;

2. The two rotating rings can be arranged in the openings at both ends of the body by convex large inlays, and then be integrated by rolling and closing the pivots;

3. Through the utility model, the opening at both ends of the body can obtain the horizontal uniform closing effect,

4. Achieve the better rotation effect of improving the combined tensile strength and flexibility.
