[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0036] Please also refer to Figures 1 to 4The clasp provided in the embodiment of the present application will now be described. This clasp can be used with a watch or other bracelet to facilitate putting the watch or bracelet on or taking it off the wrist. The clasp comprises a base frame 100, an elastic member 200, a button 300, and two flip frames 400. The base frame 100 has curved extensions on both sides, with shaft holes 104 formed on both sides of the ends of the extensions. The flip frames 400 have opposing rotating ends 410 and free ends 420. The rotating ends 410 of the two flip frames 400 are rotatably connected to the opposite ends of the base frame 100 through the engagement of pins 401 with the shaft holes 104. The flip frame 400 is a hollow structure and has a receiving groove 402 formed inside to accommodate the extension section of the corresponding side of the base frame 100. After wearing the watch on the wrist, the two flip frames 400 are rotated, folded and buckled onto the base frame 100, thereby shortening the length of the watch strap and firmly buckling the watch strap on the wrist; when the watch needs to be taken off, just press the button 300 inward to disengage the two flip frames 400 from the base frame 100, thereby increasing the length of the watch strap and taking it off.

[0037] like Figure 3 、 Figure 10 As shown, the chassis 100 is provided with a receiving groove 101 in the middle. At least one side of the receiving groove 101 is open in the width direction. An elastic member 200 is provided in the receiving groove 101. The elastic member 200 can provide a restoring force for the button 300 after being pressed. The button 300 includes a pressing portion 310, a connecting portion 320, and a plug-in portion 330 connected in sequence. The button 300 can be made of hardware or injection molding, and specifically a metal stamping part. The plug-in portion 330 is at least partially accommodated in the receiving groove 101. The connecting portion 320 is located between the plug-in portion 330 and the pressing portion 310. The connecting portion 320 extends from the opening of the receiving groove 101. The pressing portion 310 is exposed on the chassis 100, and there is a gap between the pressing portion 310 and the side wall of the chassis 100.

[0038] like Figure 1 、 Figure 3 、 Figure 6 As shown, a snap-fit structure is formed between the free end 420 of the flip frame 400 and the plug-in portion 330. The free end 420 of the flip frame 400 is snapped onto the plug-in portion 330 via this snap-fit structure. Pressing the button 300 allows the flip frame 400 to detach from the plug-in portion 330. One end of the elastic member 200 abuts against the plug-in portion 330, allowing the elastic member 200 to reset the button 300 after being pressed. The free end 420 of the flip frame 400 rotates close to the button 300 without interfering with it. Pressing the flip frame 400 allows it to snap onto the plug-in portion 330 of the button 300. To open the flip frame, press inward on the button 300 to unlock it, and then apply force to remove the free end 420 of the flip frame 400.

[0039] Compared with the prior art, the clasp provided in the present application has the following advantages: after pressing the button 300, the flip frames 400 on both sides can be detached from the base frame 100, and the free ends 420 of the flip frames 400 can be rotated to be engaged with the plug-in portion 330 of the button 300. The overall structure of the clasp is simple, using fewer parts, and the assembly operation between the parts is simple and the cost is low.

[0040] In one embodiment, please refer to Figure 1 、 Figure 5 and Figure 6 Two buttons 300 are provided, with openings on both sides of the accommodating groove 101 in the width direction. The two buttons 300 are movably mounted on opposite sides of the base frame 100 through the openings on both sides. The elastic member 200 is a spring 210 sandwiched between the plug-in portions 330 of the two buttons 300. An anti-drop structure is formed between the plug-in portion 330 and the base frame 100 to prevent the button 300 from falling out of the accommodating groove 101. In other words, two buttons 300 are symmetrically provided on opposite sides of the base frame 100. A snap-fit structure is formed between the free ends 420 of the flip frame 400 on both sides of the plug-in portion 330 of each button 300. To unlock, press the buttons 300 on both sides. The use of two buttons 300 makes the snap-fit assembly of the base frame 100 more stable and is more in line with the user's habit of applying force with two fingers.

[0041] In one embodiment, see Figure 6 、 Figure 7 and Figure 9 The anti-dropout structure includes four blocks 110 disposed in the receiving groove 101. Two of the blocks 110 are spaced apart at the opening on one side of the receiving groove 101 to prevent the corresponding button 300 from falling out of the receiving groove 101. The inner sides of the two blocks 110 abut against the plug-in portion 330 of the button 300. Another two blocks 110 are spaced apart at the opening on the other side of the receiving groove 101 to prevent the other button 300 from falling out of the receiving groove 101. The inner sides of the two blocks 110 abut against the plug-in portion 330 of the button 300. The height of each block 110 can be set to be equal to the height of the plug-in portion 330. The connecting portion 320 of the button 300 passes between the two blocks 110 on the corresponding side. The connecting portion 320 of the button 300 can be provided with a variable diameter structure. The connecting portion 320 includes a straight section and a variable diameter section of equal width. One end of the variable diameter section is connected to the pressing portion 310. The width of the variable diameter section gradually decreases from the pressing portion 310 to the plug-in portion 330. In this way, the connecting portion 320 has good structural strength and can avoid interference with the flip frame 400.

[0042] In one embodiment, see Figures 7 to 9The plug-in portion 330 includes a first rod 331 perpendicularly connected to the end of the connecting portion 320. The first rod 331 abuts against the two stoppers 110 on the corresponding side. The length of the first rod 331 matches the width of the accommodating groove 101, and the length direction of the first rod 331 is parallel to the width direction of the accommodating groove 101. The first rod 331 has latching tongues 332 at opposite ends of its outer wall. The free ends 420 of the flip frames 400 on both sides are respectively provided with slots 430 that match the latching tongues 332. The latching tongues 332 and the slots 430 form a latching structure. When the flip frame 400 is not fastened to the plug-in portion 330, at least a portion of the two latching tongues 332 on the first rod 331 protrude from the corresponding side of the base frame 100, or the outer ring of the latching tongues 332 may be exposed outside the base frame 100. When the free end 420 of the flip frame 400 is fastened to the plug-in portion 330, the flip frame 400 supports the latching tongues 332, and the two buttons 300 move toward the inside of the base frame 100. After the fastening is completed, the latching tongues 332 slide into the corresponding slots 430. Due to the elastic force of the spring 210, the flip frame 400 is fastened to the button 300 in a relatively stable manner.

[0043] In one embodiment, see Figure 1 、 Figure 8 、 Figure 11 Guide slopes are provided on the outer side of the buckle tongue 332 and / or the free end 420 of the flip frame 400 near the slot 430 to facilitate the sliding of the buckle tongue 332 into the slot 430. Specifically, a first guide slope 3320 and a second guide slope 431 can be provided on the side walls of the buckle tongue 332 opposite the free end 420 of the flip frame 400, respectively. That is, the buckle tongue 332 is provided with the first guide slope 3320, and the free end 420 of the flip frame 400 is provided with the second guide slope 431. In this way, when the flip frame 400 is buckled in, due to the provision of the two guide slopes, only a small force is required to achieve the buckling connection, which brings convenience to use.

[0044] In one embodiment, see Figures 8 to 10 The plug-in portion 330 further includes two second rods 333, which are spaced apart and disposed on the sidewall of the first rod 331 facing away from the connecting portion 320. The second rods 333 of the two buttons 300 are staggered and parallel to each other. A retaining groove 340 for accommodating the spring 210 is defined between the innermost two of the four second rods 333. The retaining groove 340 prevents the spring 210 from moving or tilting within the accommodating groove 101, thereby effectively providing a restoring force for the buttons 300 on both sides.

[0045] In one embodiment, see Figure 2 、 Figure 6 、 Figure 7The base frame 100 is provided with a groove 102, which is open on three sides. The watch buckle also includes a cover plate 130 connected to the base frame 100. Steps 120 are provided on both sides of the width direction of the groove 102. The opposite ends of the cover plate 130 respectively abut against the steps 120 on both sides. The cover plate 130 covers the groove 102, and the cover plate 130 and the groove wall of the groove 102 form a receiving groove 101. After the cover plate 130 is installed, the top surface of the cover plate 130 can be flush with the top surface of the base frame 100, which is more aesthetically pleasing. The cover plate 130 and the base frame 100 bracket can be connected and fixed using a connector, or they can be fixed using other detachable methods.

[0046] In one embodiment, see Figures 5 to 7 The cover plate 130 is fixed to the base frame 100 by screws 140. Two threaded holes 103 are provided at intervals on the base frame 100 corresponding to the grooves 102. The screws 140 pass through the cover plate 130 and are screwed into the threaded holes 103. It is understood that the threaded holes 103 can also be provided in other locations, such as on the steps 120 on both sides, to secure the cover plate 130 to the base frame 100.

[0047] In one embodiment, see Figures 8 to 10 The inner sidewall of the first rod 331 is provided with a protrusion 350. When the button 300 slides a predetermined distance into the receiving groove 101, the protrusion 350 abuts against the rod of the screw 140, thereby preventing the pressing portion 310 of the button 300 from contacting the free end 420 of the flip frame 400 when the button 300 is pressed. The arrangement of the protrusion 350 and the screw 140 prevents interference or friction between the connecting portions 330 of the two buttons 300 after being pressed, and also ensures a smooth pressing action.

[0048] One side of the protrusion 350 can be connected to the second rod 333. That is, the protrusion 350 can be located inside the connection between the first rod 331 and the second rod 333. This improves the overall structural strength of the plug portion 330 of the button 300. The distance between the second rods 333 on the corresponding sides of the two buttons 300 is adapted to the rod portion of the screw 140, which makes the structure within the receiving groove 101 more compact.

[0049] The watch provided in the embodiment of the present application includes a dial, a watch strap connected to the dial, and a clasp of the above embodiment connected to the watch strap. The above clasp arrangement makes the watch structure simple, the assembly operation is simple, and the cost is reduced.

[0050] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
