[0035]

[0036] ​The first buckle assembly 100 comprises a buckle pin 101, a buckle cap 103 and a clamping groove component 102. The buckle pin 101 has a cylindrical rear pin body section 1011, the front end of which extends axially to form a front pin body section 1012, and the outer diameter of the cylindrical rear pin body section 1011 is larger than that of the front pin body section 1012. The buckle cap 103 is sleeved on the end of the front pin body section 1012 of the buckle pin 101 by a cap head, and an annular accommodating cavity is formed between the cap body of the buckle cap 103 and the front pin body section 1012. The clamping groove component 102 is axially slidably sleeved on the front pin body section 1012 of the buckle pin 101 close to the buckle cap 103. The clamping groove component 102 has a first annular body 1022 close to the buckle cap 103 and a second annular body 1023 away from the buckle cap 103, and an annular protrusion 1021 is arranged between the first annular body 1022 and the second annular body 1023, and the clamping groove component 102 can insert at least part of the first annular body 1022 into the annular accommodating cavity of the buckle cap 103 by axial sliding. The two sides of the annular protrusion 1021 are both inclined surfaces, the annular protrusion 1021 is similar to a triangular body, the cross section of the annular protrusion 1021 is triangular, and the outer diameter of the top of the annular protrusion 1021 is not less than the outer diameter of the buckle cap 103.

[0037] Since the clamping groove component 102 is movable, a first annular groove can be formed between the annular protrusion 1021 and the buckle cap 103 on the first annular body 1022; in addition, a second annular groove is formed on the second annular body 1023 corresponding to the first annular groove, and the second annular groove is located between the annular protrusion 1021 and another annular protrusion arranged at the rear end of the second annular body 1023, or is formed between the annular protrusion 1021 and the rear pin body section of the buckle pin 101.

[0038] The second buckle assembly 200 comprises a hollow ball assembly 205 and a cylindrical assembly 201 arranged in the hollow ball assembly 205. The hollow ball assembly 205 is provided with a hole for inserting the buckle pin 101 into the cylindrical assembly 201, and in order to enable the buckle pin 101 to rotate freely when inserted into the cylindrical assembly 201, at least part of the cylindrical cavity of the cylindrical assembly 201 has a cylindrical cavity that matches the cylindrical rear pin body section 1011 of the buckle pin 101.

[0039] The cylindrical fitting 201 is provided with at least one set of buckle assembly, the buckle assembly comprises a gold nail 203 and an elastic piece, the rear end of the gold nail 203 abuts against the elastic piece, and the front end of the gold nail 203 extends into the barrel cavity of the cylindrical fitting 201 through the through hole 2011 formed in the barrel wall of the cylindrical fitting 201. Specifically, the gold nail 203 has a baffle 2031 at the tail end, and the column part 2032 extending out of the baffle 2031 is used as the front end of the gold nail 203 to extend into the barrel cavity of the cylindrical fitting 201 through the through hole 2011. The elastic piece is an elastic metal strip 202, in order to fix the elastic metal strip 202, the outer edges of the two ends of the cylindrical fitting 201 are formed with annular bosses 2012, the elastic metal strip 202 is placed in the clamping grooves 2013 formed in the bosses 2012 at the two ends respectively, and the bosses 2012 are further provided with a sealing sleeve 204 for further fixing the elastic metal strip 202. The baffle 2031 is used for abutting against the elastic metal strip 202, and simultaneously limiting the gold nail 203 from sliding into the cylindrical fitting 201 as a whole, so that the gold nail 203 has a force tending to the axis of the cylindrical fitting 201 under the action of the elastic metal strip 202, thereby cooperating with the head cap 103 and the clamping groove part 102 on the head nail 101.

[0040] The first buckle fitting 100 and the second buckle fitting 200 are connected with the chain body 300 respectively, so as to form a complete pearl chain jewelry. The chain body 300 matched with the first buckle fitting 100 is arranged at the tail of the head nail 101, and the chain body 300 matched with the second buckle fitting 200 is arranged on the hollow ball fitting 205 at the side opposite to the insertion hole. The chain body 300 is composed of a circular ring body 301 and a head cover 302, the circular ring body 301 is fixedly connected with the hollow ball fitting 205 or the head nail 101 by welding, bonding or clamping, the head cover 302 is buckled on the circular ring body 301 and is fixedly connected by welding, bonding or screw, or the threaded cooperation shown in the figure can be used for fixed connection, wherein the circular ring body 301 is provided with external threads, and the head cover 302 is provided with internal threads. The cover surface of the head cover 302 is provided with a small hole 303, and the small hole 303 is fixed by a knot. Figure 8

[0041] The specific buckle operation and mechanism of the application are as follows:

[0042] ​Locking buckle: when the head nail 101 is inserted into the hollow ball fitting 205 through the hole of the barrel fitting 201, first, the head cap 103 at the front end of the head nail 101 is in contact with the gold nail 203 at the front end, and the gold nail 203 is retreated against the elastic force of the elastic metal strip 202, in order to facilitate the head cap 103 to retreat the gold nail 203, the cap head of the head cap 103 can be provided in a spherical cap structure or rounded corner; the head nail 101 continues to advance until it slides onto the card slot component 102 and is in contact with the annular protrusion 1021, and the card slot component 102 is pushed to slide backward on the head nail 101 by a small segment, and the shaft shoulder between the nail body front segment 1012 and the nail body rear segment 1011 of the head nail 101 limits and fixes the card slot component 102, at this time, the front end of the gold nail 203 is clamped in the first annular groove on the first annular body 1022, and the gold nail 203 is limited by the cap body edge of the head cap 103, so as to realize the fixed connection of the first buckle fitting 100 and the second buckle fitting 200.

[0043] Buckle unlocking: when the locked first buckle fitting 100 and the second buckle fitting 200 need to be separated, two steps are needed. First, continue to push the head nail 101 in the direction of locking the buckle, so that the gold nail 203 slides through the annular protrusion 1021 and falls into the second annular groove on the second annular body 1023; then pull the head nail 101 in the opposite direction, the gold nail 203 will first abut against the annular protrusion 1021 and drive the card slot component 102 to slide towards the head cap 103, and the first annular body 1022 is inserted into the annular accommodating cavity of the head cap 103, so that the opening of the first annular groove is narrowed, until the card slot component 102 no longer moves; at this time, continue to pull the head nail 101, the gold nail 203 will be pushed open by the annular protrusion 1021, and the gold nail 203 will fall onto the cap body of the head cap 103, so as to realize the unlocking of the buckle, and separate the first buckle fitting 100 and the second buckle fitting 200.

[0044] In order to achieve better nail pulling, the depth of the first annular groove can be greater than the depth of the second annular groove; further, the end of the head cap 103 close to the card slot component 102 is provided with a beveled opening edge matching the slope surface of the annular protrusion 1021, so that when the card slot component 102 slides towards the head cap 103, part of the annular protrusion 1021 can be hidden in the head cap 103, so that when the gold nail passes the annular protrusion 1021, it will not fall into the first annular groove, but fall onto the head cap 103.

[0045] Although the specific embodiments of the present application are described above, those skilled in the art should understand that these are only examples, and various changes or modifications can be made to the embodiments without departing from the principles and essence of the present application, and the protection scope of the present application is only limited by the appended claims.
