[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] The adjustable chain clasp provided in this embodiment of the invention is applied to jewelry, such as... Figures 1-6 As shown, it includes: a locking seat 10 and an adjusting assembly 20;

[0046] The top of the locking seat 10 is fixedly connected to the first end of the chain 30, and the bottom of the locking seat 10 is provided with a chain through groove 11 that runs through its length, through which the second end of the chain 30 passes.

[0047] The locking seat 10 is provided with a mounting slot 12 for mounting the adjustment assembly 20;

[0048] The adjustment assembly 20 includes: an adjustment member 21, a reset member 22, and a rotating shaft 23; after the adjustment member 21 is installed in the mounting groove 12, the length direction of the adjustment member 21 is consistent with the length direction of the locking seat 10;

[0049] The adjusting member 21 has a pressing part 211, a connecting part 212 and a locking part 213 connected in sequence, and the first horizontal plane where the pressing part 211 is located and the second horizontal plane where the locking part 213 is located are parallel to each other;

[0050] The connecting part 212 has a rotating shaft through hole 214 along its width direction. The rotating shaft 23 is rotatably installed in the rotating shaft through hole 214, and the two ends of the rotating shaft 23 are respectively fixed to a pair of side walls 13 arranged along its width direction of the locking seat 10.

[0051] One end of the reset member 22 abuts against the bottom of the mounting groove 12, and the other end abuts against the pressing part 211. The clamping end of the clamping part 213 can clamp the second end of the chain 30 that passes through the chain through groove 11.

[0052] The elastic restoring force provided by the reset member 22 causes the adjusting member 21 to rotate around the rotating shaft 23, so that the clamping end of the clamping part 213 is clamped 30.

[0053] In the above technical solution, when the wearer needs to wear jewelry (including but not limited to necklaces and bracelets) with adjustable chain length clasps, the first end of the chain 30 is fixedly connected to the top of the clasp seat 10, and the second end of the chain 30 passes through the chain through groove 11. The length of the second end of the chain 30 passing through is adjusted according to the wearer's actual needs. When adjusted to an appropriate length, the elastic restoring force provided by the reset member 22 causes the adjusting member 21 to rotate around the rotating shaft 23, so that the locking end of the locking part 213 locks the chain 30. Figure 4 As shown; of course, by pressing the pressing part 211 to apply a force to the reset member 22, the elastic restoring force can be overcome, causing the chain 30 to release, and then the length of the chain 30 can be adjusted as needed, such as... Figure 5 As shown.

[0054] According to the above technical solution, by adjusting the settings of component 20, the wearer can make adaptive adjustments to the chain 30 of the jewelry according to actual needs, thereby improving the wearing comfort and enhancing the aesthetics after wearing.

[0055] Optimize the above technical solutions, such as Figure 1 and Figure 2 As shown, the reset component 22 includes: a torsion spring;

[0056] The shaft through hole 214 includes: a first shaft through hole and a second shaft through hole arranged along the width direction of the connecting part;

[0057] A slot 215 is formed between the first shaft through hole and the second shaft through hole to fit the torsion spring; the shaft 23 passes through the first shaft through hole, the torsion spring and the second shaft through hole in sequence, and fixes the torsion spring in the slot 215.

[0058] One torsion arm of the torsion spring abuts against the bottom of the mounting groove 12, and the other torsion arm abuts against the bottom surface of the pressing part 211; the top surface of the pressing part 211 is used to bear the force that overcomes the elastic restoring force, so that the clamping end of the clamping part 213 releases the second end of the chain 30.

[0059] In the above technical solution, by setting the torsion spring, the adjusting member 21 can rotate around the rotating shaft 23 under the action of force, so as to realize the locking end of the locking part 213 locking or releasing the chain 30; the torsion spring is an industrial product, which is inexpensive and helps to save the cost of this lock, and the torsion spring has a long service life.

[0060] Optimize the above technical solutions, such as Figure 1 and Figure 2 As shown, the locking seat 10 also includes two rings 14;

[0061] The mounting groove 12 is provided with side wall through grooves 15 on the side wall 13 for fixing the rotating shaft 23. Two rings 14 are respectively inserted into the corresponding side wall through grooves 15, and the two ends of the rotating shaft 23 are respectively fixed in the through holes of the corresponding rings 14.

[0062] In the above technical solution, the setting of the ring 14 facilitates the assembly of the adjusting component 21; preferably, after the ring 14 is respectively inserted into the corresponding side wall through groove 15, the ring 14 and the side wall through groove 15 are welded and fixed by welding.

[0063] In this technical solution, such as Figures 4-6 As shown, the part of the bottom surface of the pressing part 211 that abuts against one torsion arm of the torsion spring is an arc-shaped surface, and the part of the bottom surface of the mounting groove 12 that abuts against the other torsion arm of the torsion spring is an inclined surface, and the inclined surface faces the locking part 213. In this technical solution, the circumferential direction of the arc-shaped surface is the same as the circumferential direction of the rotation, and the inclined surface faces the locking part 213, so that the adjusting part 21 can rotate more smoothly.

[0064] In this technical solution, such as Figures 1-2 As shown, the latch seat 10 has a first opening surface 17 and a second opening surface 18 that are both connected to the mounting groove 12, and the first opening surface 17 and the second opening surface 18 are adjacent to each other.

[0065] The first opening surface 17 and the chain entry point of the chain through groove 11 are located on the same side, and the second opening surface 18 is part of the top surface of the lock seat 10.

[0066] One end of the pressing part 211 away from the rotating shaft 23 extends outward through the first opening surface 17, and the top surface of the pressing part 211 can be coplanar with the second opening surface 18 under the action of elastic restoring force.

[0067] The end of the pressing part 211 away from the rotating shaft 23 extends outward through the first opening surface 17, making the adjustment member 21 rotate more smoothly and avoiding interference. Furthermore, the top surface of the pressing part 211 elastically recovers its shape, which is the state when the adjustment member 21 clamps the chain 30. Figure 4 As shown; in another embodiment, the latch seat also has a third opening surface 19, which is arranged opposite to the first opening surface 17. The setting of multiple opening surfaces allows maintenance personnel to observe the connection between the various components inside the latch seat 10 without blind spots, which facilitates quick maintenance and assembly.

[0068] In this technical solution, such as Figure 2 As shown, the clamping end of the clamping part 213 is clamped in the hole 32 formed between adjacent chain units 31 of the chain 30. In this technical solution, the clamping end of the clamping part 213 clamps the hole 32, making the clamping structure between them more secure and less likely to fall off.

[0069] Optimize the above technical solutions, such as Figure 2 and Figure 4 As shown, the clamping part 213 at least partially protrudes towards the chain 30 to form a clamping end, and the length of the clamping end matches the length of the hole 32. In this technical solution, the clamping structure between the clamping end and the hole 32 is more secure and avoids falling off.

[0070] In this technical solution, the length of the chain through groove 11 is equal to half the length of the locking seat 10, and the locking end of the locking part 213 can lock the second end of the chain 30 onto the bottom wall of the locking seat 10. In this technical solution, the locking structure is made more secure by such a setting.

[0071] An ornament includes: a chain 30, and an adjustable chain length clasp as described above. The second end of the chain 30 is provided with a chain tail piece 33, which is used to pass through the chain through groove 11. The chain tail piece 33 is provided to guide the chain 30, so that the chain 30 passes through the chain through groove 11 more quickly. Of course, the length of the chain tail piece 33 is longer than the length of the chain through groove 11.

[0072] To optimize the above technical solution, the chain through groove 11 includes: two straight grooves that intersect perpendicularly to form a cross groove; the shape of the chain tail piece 33 matches the shape of each straight groove, and the length of the chain tail piece 33 is greater than the length of each straight groove, so that the chain tail piece 33 can pass through each straight groove. In the above technical solution, by setting the cross groove, when the chain tail piece 33 enters from one straight groove, the following chain 30 enters from the other straight groove.

[0073] If the chain 30 in the above embodiments needs to be adjusted to other chain types, the shape of the clamping end of the clamping part 213 needs to be adjusted accordingly so that it can fit the hole 32 of the adjusted chain type.

[0074] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0075] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
