1-6, the present invention provides a butterfly buckle 100 including a buckle body 10, an inner fork plate 20 and an outer fork plate 30. As shown in FIG. The inner fork plate 20 has one end rotatably connected to the buckle body 10 and the other end rotatably connected to the outer fork plate 30 . The buckle body 10 is provided with a cavity 11 . The inner fork plate 20 rotates around the buckle body 10 so that the outer fork plate 30 engages with the cavity 11 , and simultaneously pushes the outer fork plate 30 over the inner fork plate 20 . rotate. At this time, the outer fork plate 30 and the inner fork plate 20 are both folded and hidden in the cavity 11, and the thickness of the buckle body 10 is the thickness of the butterfly buckle 100, The appearance is ultra-thin and beautiful.

The butterfly buckle 100 further includes pressing structures 40 provided on both sides of the cavity 11 . The buckle body 10 is provided with a mounting groove 12 communicating with the cavity 11 . The pressing structure 40 includes a push button 41 that is accommodated in the mounting groove 12 so that an engaging hook 43 is connected thereto, and a combination of the buckle main body 10 and the push button 41 so that the push button 41 can expand and contract. and an elastic member 42 provided therebetween. An engaging groove 31 and an engaging rod 32 provided in the engaging groove 31 are provided on both sides of the outer fork plate 30 . When the outer fork plate 30 is engaged with the cavity 11, the engaging hook 43 extends into the engaging groove 31, and the outer fork plate 30 and the buckle body 10 are fixed. It engages with the engagement rod 32 .

Before engaging, first push the push button 41 to retract the engaging hook 43 into the cavity 11 to avoid the engaging rod 32, then the outer fork plate 30 and the inner fork. A plate 20 is rotated into said cavity 11 . At this time, the engaging hook 43 is inserted in accordance with the engaging groove 31 . After releasing the hand, resetting of the elastic member 42 causes the engaging hook 43 to extend out of the cavity 11 to engage the engaging rod 32, thereby connecting the outer fork plate 30 and the The buckle main body 10 is fixed. This engaging method is simple and highly reliable, and the disengagement phenomenon is less likely to occur, avoiding dropping from the wrist and loss, and improving the safety of use.

In this embodiment, the push button 41 and the engaging hook 43 may be integrally molded to improve structural rigidity.

2 and 5, the engaging hook 43 includes a connecting portion 431, a projecting portion 432 and a straight hook portion 433. As shown in FIG. The connection part 431 is fixedly connected to the push button 41 . The straight hook portion 433 is connected to the connecting portion 431 by the projecting portion 432 . The straight hook portion 433 , the protrusion portion 432 and the connection portion 431 surround the groove 434 . The engaging rod 32 is accommodated in the groove 434 when the outer fork plate 30 is connected to the buckle body 10 . The straight hook portion 433 hooks the engagement rod 32 and becomes difficult to separate, thereby maintaining the engagement state of the butterfly buckle 100 .

Further, a pair of positioning blocks 411 are protrudingly provided on both sides of the push button 41 with a space therebetween, and a movable space 412 is formed between the two positioning blocks 411 . The buckle body 10 is provided with limiting posts 13 that are accommodated in the movable space 412 on both sides of the mounting groove 12 . By accommodating the restricting post 13 in the movable space 412, it is ensured that the push button 41 performs an expansion and contraction operation in the movable space 412 so as to complete the engagement or disengagement operation. It is possible to prevent the push button 41 from falling out of the mounting groove 12 and causing the disengagement phenomenon.

Preferably, the buckle body 10 is provided with a spring bar 14 at one end. The inner fork plate 20 is connected with the spring bar 14 by a first rotating shaft 21 . A through groove 33 is provided in the outer fork plate 30 . The inner fork plate 20 is connected to the outer fork plate 30 by a second rotary shaft 22 so as to be accommodated in the through groove 33 . Thereby, the inner fork plate 20 and the outer fork plate 30 can be folded to reduce the occupied volume, thereby reducing the thickness of the butterfly buckle 100 .

Specifically, the outer fork plate 30 is provided with a receiving groove 34 at one end spaced apart from the inner fork plate 20 . When the outer fork plate 30 is engaged with the cavity 11 , the receiving groove 34 is in close contact with the second rotating shaft 22 . Accordingly, the thickness of the butterfly buckle 100 is reduced.

In this embodiment, the push button 41 is provided with a positioning groove 413 on one side facing the mounting groove 12 . The elastic member 42 is attached to the positioning groove 413 . As a result, the mounting stability of the elastic member 42 is improved, and the occurrence of offset is avoided.

In this embodiment, the outer fork plate 30 is provided with a first mounting hole 35 at one end spaced apart from the inner fork plate 20 . The buckle body 10 is provided with a second mounting hole 15 at one end spaced apart from the inner fork plate 20 . Said first mounting hole 35 and second mounting hole 15 are respectively used to connect with the corresponding band for convenient wearing on the user's wrist.

According to the present invention, there is further provided a wristwatch comprising a left band, a right band and a dial, wherein the left band and the right band are connected by the aforementioned butterfly buckle 100 . The appearance is beautiful, the reliability of the engagement is high, the engagement disengagement phenomenon hardly occurs, the drop from the wrist and the loss are avoided, and the safety of use is improved.

It should be noted that the above examples of the present invention are merely examples given to clearly describe the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different modifications or variations can be made based on the above description. Not all embodiments can be listed here. Any obvious modification or variation derived from the technical means belonging to the present invention shall still fall within the protection scope of the present invention.
