Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0060] [Example 1]

[0061] As a specific example, Figures 3 to 5 As shown, this embodiment is a sliding locking clasp, which includes a male buckle 100 and a female buckle 200 that can cooperate with each other. Different from the traditional clasp, the female buckle 200 is provided with a strap adjustment channel 230 that can move along the length direction of the strap 400, so that the use length of the strap 400 can be adjusted.

[0062] Specifically, Fig.13 As shown, a strap fixing position 110 is provided at one end of the male buckle 100. In the drawings of this embodiment, a groove 222 for fixing the end of the strap 400 is provided at the strap fixing position 110, and rivet connection or other fixing methods can also be used.

[0063] Further, the female buckle 200 includes a strap adjustment portion 210 and a male buckle fastening portion 220, the strap adjustment portion 210 is located on a side of the male buckle fastening portion 220 away from the strap fixing position 110, and the male buckle fastening portion 220 and the male buckle 100 have a corresponding fastening surface 221, such as Figure 4 As shown, the strap adjustment portion 210 and the male buckle fastening portion 220 have a penetrating strap adjustment channel 230 on the side away from the male buckle 100, which is used to pass through the strap body so that the female buckle 200 can move along the length direction of the strap 400, thereby adjusting the distance between the dial and the female buckle 200, that is, the usable length of the strap 400.

[0064] Furthermore, the strap adjustment part 210 is a hollow structure, a button hole 211 is provided in the strap adjustment part 210 along the width direction of the strap, a through hole 212 connected to the strap adjustment channel 230 is provided in the thickness direction, and a locking assembly 300 is provided inside the strap adjustment part 210. In other words, the relative fixation between the strap and the female buckle 200 is achieved by the locking assembly 300 inside the strap adjustment part 210.

[0065] Further, the locking assembly 300 includes a pressing plate 310, a female buckle button 320 and a plurality of elastic elements 330, the pressing plate 310 is slidably mounted in the through hole 212, the pressing plate 310 has a strap locking surface 311 on the side close to the strap adjustment channel 230, the female buckle button 320 is slidably mounted in the button hole 211, the elastic element 330 is mounted in the sliding direction of the female buckle button 320 and the pressing plate 310, and the inner side of the female buckle button 320 and the side of the pressing plate 310 away from the strap adjustment channel 230 respectively have mutually cooperating action surfaces, so that the female buckle button 320 can apply a component force to the pressing plate 310 along the sliding direction of the pressing plate 310. Preferably, the elastic element 330 is a spring, the strap adjustment portion 210 and the male buckle fastening portion 220 are an integrated structure, and the female buckle button 320 and the pressing plate 310 are both an integrated structure.

[0066] Furthermore, the state conversion of the two sliding locking clasps can be realized by pressing the female buckle button 320. In the natural state, that is, the non-pressed state, Figure 7 , Fig. 9 and Fig.10 As shown, the pressure plate 310 is maintained at the first preset position, and the strap locking surface 311 is located inside the strap adjustment channel 230, and can act on the strap to limit the strap from sliding in the strap adjustment channel 230. In other words, the pressure plate 310 squeezes out the female buckle button 320 under the action of the elastic element 330. At the same time, the pressure plate 310 is also in the limit position, i.e., the first preset position, under the action of the elastic element 330. At this position, the pressure plate 310 can apply force to the strap, so that when the strap has a tendency to slide along its length direction, sufficient friction can be generated to keep the strap relatively still with the female buckle 200. In addition, the strap locking surface 311 can also increase the resistance to the strap by providing a sufficient number of convex studs.

[0067] Furthermore, in the pressed state, Figure 8 , Fig.11 and Fig.12 As shown, the female buckle button 320 drives the pressure plate 310 to move to the second preset position, and the strap locking surface 311 is separated from the strap. In other words, by pressing the female buckle button 320, the pressure plate 310 can slide in a direction away from the strap, at which time, the strap locking surface 311 stops contacting the strap, causing the strap to no longer be resisted by the pressure plate 310, so that the strap can move along its length direction.

[0068] In a preferred embodiment, Fig.13 As shown, the male buckle 100 includes a male buckle body 120, a spring and two oppositely arranged male buckle buttons 130, a sliding cavity 121 of the male buckle button 130 is arranged inside the male buckle body 120, and the male buckle button 130 can be rebounded and installed in the sliding cavity 121 through the spring, the sliding direction of the male buckle button 130 is consistent with the sliding direction of the female buckle button 320, and a buckle cap 131 is arranged on the side of the male buckle button 130 close to the female buckle 200. Preferably, the buckle cap 131 is mushroom-shaped, that is, the top size is larger and the middle size is thinner. In the process of matching with the first cover plate 240, under the action of the spring, the two male buckle buttons 130 are pushed outward along the width direction of the strap, so that the top of the buckle cap 131 is stuck in the edge of the limiting hole 241, and the male buckle 100 can be prevented from being separated from the female buckle 200.

[0069] Furthermore, if Figure 6 As shown, a first cover plate 240 is provided on one side of the male buckle fastening part 220 close to the male buckle 100, and a plurality of limiting holes 241 are provided on the surface of the first cover plate 240. The male buckle fastening part 220 is provided with a groove 222 corresponding to the limiting hole 241, and the groove 222 is matched with the fastening cap 131, and the inner diameter of the limiting hole 241 is smaller than the opening of the groove 222. Whether the male buckle button 130 is pressed has two states, the fastening state and the pressing state. It should be noted that the difference between the pressing state and the previous pressing state is that the pressing object is different.

[0070] Specifically, in the buckled state, the male buckle body 120 is fitted with the male buckle buckle part 220, and the male buckle button 130 is clamped in the limiting hole 241 under the action of the spring. In the pressed state, the two male buckle buttons 130 are close to each other under the action of external force, and the buckle cap 131 moves in the groove 222 to a position corresponding to the limiting hole 241, so that the buckle cap 131 can be separated from the limiting hole 241.

[0071] Further preferably, the female buckle 200 includes a first magnet, and a first receiving groove is provided on a side of the male buckle fastening portion 220 close to the male buckle 100, and the first magnet is fixed in the first receiving groove through the first cover plate 240. The male buckle 100 includes a second cover plate 140 and a second magnet, and a second receiving groove 122 corresponding to the first receiving groove is provided on the male buckle body 120, and the second magnet is fixed in the second receiving groove 122 through the second cover plate 140, and a mounting hole 141 corresponding to the fastening cap 131 is provided on the surface of the second cover plate 140. It should be noted that the specific structure of the first magnet and the second magnet is not shown in the drawings of this embodiment, but those skilled in the art should understand that the first magnet and the second magnet have opposite magnetic properties on the opposite sides, and their shapes and sizes match the first receiving groove and the second receiving groove 122. In practical applications, the male buckle button 130 and the second magnet are installed first, and then the buckle cap 131 is passed through the mounting hole 141, and the second cover plate 140 is fixed to the side of the male buckle body 120 close to the female buckle 200 to fix the male buckle button 130 and the second magnet.

[0072] In a preferred embodiment, Figure 5 , Figure 7 and Figure 8 As shown, the pressing plate 310 includes a pressing plate body 312 and a matching portion 313. The pressing plate body 312 has a strap locking surface 311 on one side facing the strap adjustment channel 230. The matching portion 313 is arranged on the side of the pressing plate body 312 away from the strap locking surface 311. The female buckle button 320 includes a button body 321 and an action portion 322. The button body 321 is arranged along the sliding direction of the female buckle button 320 and is located above the pressing plate body 312. The action portion 322 is located on the side of the button body 321 close to the pressing plate 310. In the drawings of this embodiment, the button body 321 is arranged along the width direction of the female buckle 200, and its sliding direction is consistent with the width direction of the female buckle 200.

[0073] Preferably, along the sliding direction of the female buckle button 320, the matching portion 313 has a first action surface 313-a, and the first action surface 313-a forms an acute angle with the pressure plate body 312.

[0076] Further preferably, button holes 211 are respectively provided on both sides of the strap adjustment portion 210, and female buckle buttons 320 are respectively installed in the button holes 211, and matching portions 313 corresponding to the female buckle buttons 320 are respectively provided on the pressure plate body 312, and the opposite sides of the female buckle buttons 320 are connected through elastic elements 330.

[0077] Furthermore, a plurality of bosses 312-a are provided on the side of the pressure plate body 312 away from the strap adjustment channel 230, and the elastic element 330 is installed on the bosses 312-a, and the elastic element 330 is located between the pressure plate body 312 and the inner upper cavity surface of the strap adjustment part 210. Preferably, a boss 312-a is provided on each of the four corners of the pressure plate body 312, and a spring is sleeved on the boss 312-a, one end of the spring presses against the pressure plate 310, and the other end presses against the inner side wall of the upper end of the strap adjustment part 210. The spring is assembled to provide pre-pressure, and under the action of the pre-pressure, the pressure plate 310 is ejected to the lowest working position, blocked by the limit step 212-a and in a static state.

[0078] In actual application, the female buckle button 320 is installed inside the female buckle 200 through the button hole 211, and the inside of the strap adjustment channel 230 is used to penetrate the strap body 410. Through the locking assembly 300, the female buckle button 320 can be pressed or released to achieve the loosening and locking of the strap body 410. In actual operation, the female buckle button 320 is pressed in the middle with two fingers, and the pressure plate 310 is in a free sliding and loosening state on the strap body 410. When the female buckle button 320 is moved to a certain place to release the female buckle button 320, the pressure plate 310 is in a locked state and cannot slide on the strap body 410. In this way, whether the watch is worn or not, whether the male buckle button 130 is buckled or not, the relative position of the pressure plate 310 on the strap body 410 can be adjusted in any state, thereby adjusting the wearing length of the strap to meet the needs of individual wrist circumference, and at the same time, instant adjustment during the wearing process.

[0079] [Example 2]

[0080] like Figure 1 and Figure 2 As shown, this embodiment is a watch strap 400, which includes any sliding locking buckle in the first embodiment, and further includes a watch strap body 410, a first connecting member 420 and a second connecting member 430, wherein the same parts are not repeated here.

[0081] Specifically, the first connector 420 is located on one side of the female buckle 200, the second connector 430 is located on one side of the male buckle 100, and the first connector 420 and the opposite side of the first connector 420 respectively have a dial connection position 440; the second connector 430 is provided with a strap through hole 431 along the width direction of the strap body 410 at one end close to the male buckle 100. In the drawings of this embodiment, the first connector 420 and the second connector 430 are both provided with a hinge hole for hingedly connecting the dial at one end away from the sliding locking clasp. In addition, the first connector 420 and the second connector 430 can also adopt other connection structures at the position of the hinge hole to achieve the connection to the dial.

[0082] Furthermore, one end of the strap body 410 is connected to the first connecting member 420 , and the other end passes through the strap adjustment channel 230 and the strap through hole 431 in sequence and is fixed to the strap fixing position 110 .

[0083] Further preferably, the strap body 410 cooperates with the strap adjustment channel 230. In a natural state, the strap locking surface 311 squeezes the strap body 410 to generate a friction force to prevent the strap body 410 from slipping along the strap adjustment channel 230; in a pressed state, the strap locking surface 311 moves toward the through hole 212 and disengages from the strap body 410.

[0084] Furthermore, if Fig.14As shown, a strap interface 421 is provided at one end of the first connecting member 420 close to the female buckle 200 . The strap interface 421 matches the shape of the strap, and the strap body 410 is clamped in the strap interface 421 .

[0085] In practical applications, the strap body 410 is made of woven fabrics, such as soft rubber, leather and other deformable materials. The first connector 420 can be fastened to the strap body 410 by in-mold injection molding, viscose and other methods. Before fastening by in-mold injection molding, viscose and other methods, the end of the strap body 410 needs to be subjected to plastic treatment such as hot pressing and punching to increase the connection area and form an undercut to obtain good fastening connection performance, so that the strap is not easy to loosen.

[0086] [Example 3]

[0087] like Figures 1 to 14 As shown, this embodiment is a watch, which includes any one of the straps 400 in the second embodiment, and further includes a dial, wherein the same parts are not repeated here.

[0088] Specifically, two ends of the dial are hingedly connected to the first connecting member 420 and the second connecting member 430 respectively.

[0089] In actual application, when the strap body 410 has passed through the strap adjustment channel 230, without pressing the female buckle button 320, the pressure plate 310 is pushed out to the lower working position by the spring, that is, the pressure plate 310 moves to the first preset position until the strap body 410 is pressed and cannot move downward any further. At this time, the pressure plate 310 has not yet been pushed out to the lowest working position, that is, the first preset position, and a small gap is retained between the limiting step 212-a and the first limiting portion 314. In this state, since the pressure plate 310 has pressed the strap body 410, sufficient friction can be provided to ensure that no sliding displacement occurs between the strap body 410 and the female buckle 200 under normal stress conditions. When the female buckle buttons 320 on both sides are pressed, the female buckle buttons 320 slide radially toward the middle, and the pressure plate 310 moves upward under the interaction with the matching portion 313 and the action portion 322. When the female buckle button 320 is pressed to the bottom, the pressing plate 310 moves up to the maximum position and is flush with the lower edge of the inner wall of the through hole 212. In this state, the strap body 410 loses the friction resistance of the pressing plate 310, that is, the sliding displacement between the strap body 410 and the female buckle 200 can be achieved. When the female buckle button 320 is released, the female buckle button 320 and the pressing plate 310 are reset at the same time under the action of the spring, and return to the natural state, or the working state of pressing the strap body 410.

[0090] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
