Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings.

Referring to Fig. 1, a metal safety buckle includes a buckle body 1 arranged in an "8" shape, two movable rods 2 for sealing the opening of the buckle body 1, and for making the movable rod 2 elastic Rebound elastic part 3, the button body 1 is provided with a hinged part 11 and a contact part 12 respectively connected with the two ends of the movable rod 2, the movable rod 2 is hollow, and the elastic part 3 is installed In the movable rod 2, one end of the elastic member 3 is elastically contacted with the hinge part 11 of the button body 1, the contact part 12 is provided with a first threaded part 121, and the movable rod 2 is provided with the first threaded part 121. The second threaded portion 21 with the same shape as the threaded portion 121 and the first threaded portion 121 are covered with the movable locking sleeve 4 , and the inner surface of the movable locking sleeve 4 is provided with a third threaded portion 41 matching with the first threaded portion 121 .

Adopting the above-mentioned technical scheme, the buckle body 1 arranged in the shape of "8" and the two movable rods 2 together form two mutually independent buckle rings, which makes the fastening method between the metal safety buckle and the connecting rope more efficient. Diversified to meet different use requirements. The elastic member 3 is installed in the movable rod 2, and the assembly is simple, which can effectively reduce the time of assembly and reduce the cost. The button body 1 and the movable rod 2 of this embodiment can The sleeve 4 is threaded and locked firmly, and the use safety is higher.

The elastic member 3 in this embodiment is a coil spring, so that the material cost of this embodiment can be greatly reduced, and the manufacturing cost is lower.
