For ordinary skilled in the art, the above-mentioned terms can be understood according to the specific meaning of the utility model.

[0025] The utility model will be further described below in connection with the preferred embodiments and the drawings.

[0026] Please refer to the drawings Figure 1 And the drawings Figure 2 Wherein a kind of elastic clamping jewelry lock fittings is shown, the jewelry lock fittings includes buckle seat body 10 and clamping end 20, the clamping end 20 of the buckle seat body 10 and respectively has one end with the two ends of jewelry rope chain fixed connection, buckle seat body 10 and clamping end 20 are respectively installed in the two ends of the rope chain to be moved and buckled, and the opening and buckling of necklace, bracelet are completed by buckle seat body 10 and clamping end 20.

[0027] The other end of buckle seat body 10 and clamping end 20 is then inserted into buckle seat body 10 by the clamping end 20 and movable clamping locking, the one end of the buckle seat body 10 towards clamping end 20 has inner hole 11, movable rotating clamping assembly 30 is arranged in the inner hole 11, the movable rotating clamping assembly 30 includes spring 31, gasket 32 and positioning pin 33, the insertion shaft head 21 is on the clamping end 20, the insertion shaft head 21 is inserted into the inner hole 11 of buckle seat body 10 and cooperates with movable rotating clamping assembly 30 and clamps.

[0028] Positioning pin 33 is arranged in the inner hole 11 of buckle seat body 10 along the radial direction, while gasket 32 clamps spring 31 in the inner hole 11 inside positioning pin 33, and U-shaped slot 22 is arranged on the insertion shaft head 21 of the clamping end 20, and the two different states that U-shaped slot 22 is switched by positioning pin 33 and clamped / detached from positioning pin are switched by the clamping end 20.

[0029] The U-shaped clamping groove 22 contains two ends along the outer periphery of the insertion shaft head 21, one end is a blind hole groove 222 and the other end is a through hole groove 221. When the clamping end 20 is rotated to the opposite positioning pin 33 of the blind hole groove 222, the spring 31 pushes the gasket 32 to move the clamping end 20 outward, and the positioning pin 33 is clamped in the blind hole groove 222. The clamping end 20 is locked in the clasp seat body 10 by the movable rotating clamping assembly 30; when the clamping end 20 is rotated to the opposite positioning pin 33 of the through hole groove 221, the spring 31 pushes the gasket 32 to move the clamping end 20 outward, and the positioning pin 33 slips out of the through hole groove 221. The clamping end 20 is relatively disengaged from the clamping seat body 10.

[0030] The movable rotating clamping assembly 30 includes a spring 31, a gasket 32, and a positioning pin 33. The spring 31, the gasket 32, and the two positioning pins 33 are arranged in the inner hole 11 of the clasp seat body 10. The gasket 32 is arranged at the deepest part of the inner hole 11 by pressing the spring 31, and the positioning pin 33 extends from the inner hole wall in the radial direction of the inner hole 11 to limit the gasket 32 and the spring 31. There is a spacing between the two positioning pins 33, which can accommodate the U-shaped clamping groove 22 of the insertion shaft head 21.

[0031] Please refer to the attached Figure 3 The U-shaped clamping groove 22 on the insertion shaft head 21 is shown, which includes a through hole groove 221, a blind hole groove 222, and a guide groove 223 connecting the through hole groove 221 and the blind hole groove 222. When the insertion shaft head 21 compresses the spring 31 by pressing the gasket 32, the positioning pin 33 is guided and slid in the through hole groove 221 of the U-shaped clamping groove 22 and rotated by an angle to be limited in the blind hole groove 222. In this way, the opening and locking of the movable rotating clamping structure are switched.

[0032] That is, when the insertion shaft head 21 of the clamping end 20 is inserted into the inner hole 11 of the clasp seat body 10, the through hole groove 221 of the U-shaped clamping groove 22 should be aligned with the positioning pin 33, and then the clamping end 20 is pushed to allow the insertion shaft head 21 to pass between the two positioning pins 33 and press the gasket 32 and the spring 31 inward. Then the clamping end 20 is turned into the blind hole groove 222 along the through hole groove 221 through the guide groove 223. At this time, under the condition that the external pushing pressure of the clamping end 20 is released, the spring rebounds to push the gasket to reset, and the gasket presses against the insertion shaft head 21. The blind hole groove 222 clamps the positioning pin 33, and the locking and limiting between the clasp seat body 10 and the clamping end 20 are maintained.

[0033] The through hole groove 221 and the blind hole groove 222 of the U-shaped clamping groove 22 are parallel to the axis of the insertion shaft head 21, corresponding to the orientation of the two positioning pins 33. Two U-shaped clamping grooves 22 are arranged in the circumferential direction of the insertion shaft head 21.

[0034] The two positioning pins 33 in the active rotary clamping assembly 30 are 180 degrees apart in circumference, and the corresponding two U-shaped clamping grooves 22 are also 180 degrees apart, and the through holes and blind hole grooves of the two U-shaped clamping grooves 22 are uniformly distributed along the circumference of the shaft head and are 90 degrees apart from each other.

[0035] The elastic clamping jewelry lock buckle of the utility model connects the two ends of the jewelry rope chain to be opened and closed through the clamping seat body and the clamping end, realizes the opening and locking of the two ends of the jewelry rope chain, and the insertion shaft head provided with the clamping groove is self-positioned and inserted and then slides into the alignment, the sliding locking structure realizes the pushing and locking through the elastic force of the spring, the structure design is exquisite, the reliability is high, and the single-hand operation is suitable. The use experience of consumers is better, and the wearing process is simpler.

[0036] The above is only the preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as above, it is not intended to limit the utility model. Any skilled person in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the utility model technical scheme, and any simple modification, equivalent change and modification of the above embodiment within the scope of the utility model technical scheme are all within the scope of the utility model technical scheme.
