Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The utility model provides the following technical scheme;

as shown in fig. 1-6, a retractable necklace and its locking structure, comprising a necklace 1, two ends of the necklace 1 are connected by a locking 2, two sides of the locking 2 are symmetrically provided with a first through hole 21, two ends of the necklace 1 are respectively disposed in the first through holes 21, two side walls of the locking 2 are both rotatably provided with a first bolt 22, the first bolt 22 penetrates through the side wall of the locking 2, and one end of the first bolt disposed in the locking 2 is connected with a pressing block 4, a sliding groove 23 for the pressing block 4 to move is disposed in the locking 2, the sliding groove 23 is communicated with the first through hole 21, and an internal threaded hole for the first bolt 22 to rotate is disposed on the side wall of the locking 2, by the above arrangement, when the diameter of the necklace 1 needs to be adjusted, one of the first bolts 22 is tightened, so that the pressing block 4 connected with the first bolt 22 does not press one end of the necklace 1, the other bolt 22 is tightened, so that the pressing block 4 connected with the first bolt 22 presses one end of the necklace, then remove hasp 2 again for 2 one ends of hasp pulling necklace 1 move, the other end of necklace 1 then can remove in through-hole 21, thereby reach the purpose of adjusting 1 diameter size of necklace, make this necklace 1 can adapt to the crowd of the not equidimension of neck, promoted the suitability of this necklace, when needs expand necklace 1, only need unscrew bolt 22 of 2 both sides this moment, then with the both ends of necklace 1 take out in through-hole 21 can.

Specifically, the method comprises the following steps: through the above arrangement, after the diameter of the necklace 1 is adjusted, one section of the necklace 1 can be added into the necklace 1 at the moment, the bolt II 31 can be unscrewed at the moment, then the annular buckle 3 is pulled, and the annular buckle 3 is pulled, because the redundant section of the necklace 1 is fixed by the through hole III 33, the redundant section of the necklace 1 can extend in the moving process, then the bolt II 31 is screwed, one end of the redundant section of the necklace 1 is fixed, so that after the diameter of the necklace 1 is adjusted, the excess length can be unfolded and fixed, so that the beauty of the necklace 1 after the diameter is adjusted is not influenced.

Specifically, the method comprises the following steps: be equipped with buffer layer 41 on the lateral wall of briquetting 4, through such setting, when the both ends at fixed necklace 1, can not damage necklace 1 through buffer layer 41 to this protects necklace 1.

Specifically, the method comprises the following steps: hasp 2 is the rectangle setting, and the edge of hasp 2 all is the radius angle and handles, and through such setting, when necklace 1 takes on user's neck, hasp 2 can not fish tail person's of wearing skin.
