Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 3, the chain connecting assembly includes two interlocking connecting rings 1, the connecting rings 1 have openings 2, and the openings 2 of the two connecting rings 1 are disposed opposite to each other.

The connecting ring 1 is an integrally formed structure and comprises a ring part 11 and connecting lug parts 12.

Connect and be provided with pinhole 121 on the ear 12, be provided with round pin axle 3 between the ear 12, pinhole 121 is run through at the both ends of round pin axle 3 to be fixed in on connecting ear 12 through spring catch 4, be convenient for installation and dismantlement, connect ear 12 and be platelike setting, improve the structural strength who connects ear 12.

Two connection ear 12 parallel arrangement form the accommodation space 5 that can install the chain, and the edge has direction inclined plane 122 on connecting ear 12 inboard, and the chain of being convenient for sets along direction inclined plane 122, improves the convenience of using.

The loop portion 11 includes a first connection section 111, a second connection section 112, and a lower arc section 113.

The inner side area of the lower arc section 113 protrudes to both sides to form the reinforcing convex parts 13a, and the two lower arc sections 113 are mutually abutted, so that the reinforcing convex parts 13a of the lower arc sections 113 are mutually abutted, the stress area is increased, the pressure is dispersed, and the bearing capacity of the connecting ring 1 is improved.
