The connecting end 231 of the clip 23 is rotatably connected to the rotating member 22, and the free end 232 rotates with the connecting end 231 to form a snap-fitting cavity. The clamping cover 24 is connected to the side of the working cavity near the opening. The clamping cover 24 is provided with a through-hole and a first snap-fitting position 241 and a second snap-fitting position 242. The fastener 3 passes through the opening and the through-hole and abuts against the rotating member 22. The fastener 3 is provided with a snap-fitting groove 31, and the free end 232 snaps into the snap-fitting groove 31. Here, the snap-fitting cavity is the space enclosed between at least the two free ends 232. The fastener 3 extends into the snap-fitting cavity. When the push-type opening and closing buckle is in the open state, the fastener 3 can be withdrawn from the snap-fitting cavity. When the push-type opening and closing buckle is in the closed state, the fastener 3 is locked in the snap-fitting cavity and cannot be withdrawn.

[0045] Optionally, the snap action assembly 2 further includes an anti-blocking sheet 25, which is disposed between the elastic member 21 and the rotating member 22. The anti-blocking sheet 25 can stabilize the relationship between the rotating member 22 compressing the elastic member 21 or the elastic member 21 pushing the rotating member 22. Optionally, the elastic member 21 is a spring, and the anti-blocking sheet 25 is a disc.

[0046] See also Figures 4 to 8 , wherein, the latch 3 is pressed, the latch 3 pushes the rotating member 22, and the guide portion 11 is displaced to the first angular position under the guidance of the guide groove 221, and the free end 232 of the clip 23 is engaged with the first engaging position 241, and the free end 232 of the clip 23 is engaged and fastened to the engaging groove 31, so that the opening and closing latch is in the closed state; continue to press the latch 3, the latch 3 pushes the rotating member 22, and the guide portion 11 is displaced from the first angular position to the second angular position, and the free end 232 of the clip 23 is transferred to the second engaging position 242, and the free end 232 of the clip 23 is changed from the engaged state to the open state, so that the latch 3 can be withdrawn from the engaging cavity.

[0047] In this embodiment, the press-type opening and closing buckle has two states, open and closed. In the open state, the buckle 3 can be pulled out from the buckle shell 1, and in the closed state, the buckle 3 is fastened by the clip 23 in the buckle shell 1 and cannot be pulled out; the switching between the open and closed states is completed by pressing the buckle 3. Press once to open the opening and closing buckle, and press again to close the opening and closing buckle.

[0048] In one embodiment, the guide groove 221 includes an upper sidewall 2211 and a lower sidewall 2212. Both the upper sidewall 2211 and the lower sidewall 2212 are wavy in shape. The troughs of the upper sidewall 2211 and the troughs of the corresponding lower sidewall 2212 are axially offset, and the first and second angular positions are defined as any two adjacent troughs on the lower sidewall 2212. It should be noted that the upper sidewall 2211 and the lower sidewall 2212 have the same wavy shape. The upper sidewall 2211 refers to the groove wall on the side close to the clip 23, and the lower sidewall 2212 refers to the groove wall on the side close to the elastic member 21.

[0049] When the guide portion 11 is in contact with the lower side wall 2212, it will move to the next lower side wall 2212 trough along with the waveform of the lower side wall 2212, thereby completing the state switching of the push-button opening and closing buckle. Preferably, the upper side wall 2211 and the lower side wall 2212 are wavy with a sinusoidal waveform.

[0050] Optionally, the guide groove 221 forms a closed annular cavity around the side wall of the rotating member 22, that is, the guide groove 221 is connected end to end around the side wall of the rotating member 22. Optionally, the buckling groove 31 is an annular groove recessed on the side wall of the buckle 3.

[0051] Furthermore, the rotating part 22 is a bearing part, which includes an inner ring and an outer ring, which are rotatably connected. The guide groove 221 is opened on the side wall of the outer ring, and the snap part 3 abuts against the inner ring of the bearing part, thereby reducing the friction resistance between the rotating part 22 and the snap part 3 when the rotating part 22 and the snap shell 1 rotate relative to each other.

[0052] In one embodiment, the clamping cover 24 includes a clamping cover 24 body, the first latching position 241 is an inclined surface with an inwardly inclined edge provided on the clamping cover 24 body, and the second latching position 242 is an inclined surface with an outwardly inclined edge provided on the clamping cover 24 body.

[0053] Furthermore, the free end 232 of the clip 23 includes: a snap-fit ​​protrusion 2321, a first guide surface 2322 and a second guide surface 2323. The first guide surface 2322 is formed by extending the snap-fit ​​protrusion 2321 toward the top of the free end 232, and the second guide surface 2323 is formed by extending downward from the top of the first guide surface 2322. Moreover, the first guide surface 2322 corresponds to the second snap-fit ​​position 242, and the second guide surface 2323 corresponds to the first snap-fit ​​position 241.

[0054] In this embodiment, the clip 23 rotates along with the rotating member 22. When the free end 232 is located in the first engaging position 241, the second guide surface 2323 abuts against the first engaging position 241, preventing the connection end 231 from rotating. This means the clips 23 cannot move away from each other, and the engaging protrusion 2321 is firmly engaged in the engaging groove 31, preventing the clip 3 from being withdrawn. When the free end 232 is located in the second engaging position 242, the first guide surface 2322 abuts against the second engaging position 242, allowing the first guide surface 2322 to expand outward along the second engaging position 242. At this point, when the clip 3 is pulled outward, the connection end 231 rotates, the clips 23 move away from each other, and the engaging protrusion 2321 disengages from the engaging groove 31, allowing the clip 3 to be withdrawn.

[0055] See also Figures 9 and 10 The present invention also provides a bracelet comprising an opening and closing buckle as described above, a first main body 4 connected to the buckle shell 1, and a second main body 5 connected to the buckle part 3.

[0056] The push-to-open and close buckle of this embodiment can also be used in jewelry structures such as pendants and necklaces.

[0057] Compared with the prior art, the push-type opening and closing buckle of the present invention has the elastic part, rotating part, clip and clamping cover all arranged in the buckle shell, so that the action parts are hidden inside the buckle shell, ensuring the stability of the operation of the action parts, and the appearance of the opening and closing buckle is more integrated and more beautiful.

[0058] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention.
