Description

A never-loose connecting ring

technical field

The utility model relates to the technical field of connecting rings, in particular disclosing a never loose connecting ring.

Background technique

There are many functions of the chain. When the chain is connected, a connecting ring is needed. The most common connecting ring is a crescent-shaped hook. The crescent-shaped hook includes two hook ears, and a fastening ring hole is provided in the middle, and the two chains are respectively connected. On both lugs, a tensioning clasp is inserted into the tensioning clasp hole at one end and shares a lug with a chain at the other end. This structure has the following disadvantages: when the resultant force on the two hook lugs is less than the force on the tension buckle, the chain on the hook lug will slide considerably, because the openings of the two hook lugs are facing the same direction and A large opening is formed, and the chain can easily fall out of the large opening during sliding.

In order to solve the above-mentioned technical problems, the applicant submitted a Chinese invention patent application with the publication number CN112065929A before. The links of the chain snap into the opening in the connecting ring and the hooks on both sides of the opening, the hooks are used to connect with the links of the chain, and the gap space between the two connecting ends of the connecting ring forms the said The opening also includes a locking piece detachably connected to the connecting ring, and the locking piece can be locked and connected with the two connecting ends of the connecting ring, so that the connecting ring is in a closed state at the opening position. Its specific embodiment records that the locking member includes two locking plates and a locking pin, and the two locking plates can be fastened together, and are securely locked together by the locking pins. The above solution improves the reliability of the connector, but it has the disadvantages of complex structure and inconvenient assembly and disassembly.
