Description

Technical Field

[0001] The present invention relates to the technical field of wearable devices, and more particularly to a watch strap and a watch. Background Art

[0002] Traditional watchbands, such as metal watchbands, typically use pins to connect beads, and the spacing between beads is fixed. Because newly purchased watchbands may not perfectly match the wrist of the wearer, adjusting the length of the watchband requires adding or removing beads to adapt the strap to the wrists of different user groups. However, adding or removing beads requires specialized tools to insert and remove the pins, and the process is complex and time-consuming.

[0003] Based on this, it is urgent to invent a watch strap and a watch to solve the technical problems mentioned above. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the process of adding or removing part of the bead components is complicated. In order to solve the above problem, a watch strap and a watch are provided.

[0005] The technical solution of the present invention to solve the above technical problems is to provide a watch strap and a watch, wherein the watch strap comprises:

[0006] Multiple bead assemblies, each bead assembly includes a first side bead, a second side bead and a center bead pivotally connected between the first side bead and the second side bead arranged side by side, the head end of the center bead protrudes from the head ends of the first side bead and the second side bead to form a first connecting portion; the tail ends of the first side bead and the second side bead protrude from the tail end of the center bead to form a second connecting portion.

[0007] A quick-release assembly includes a level pin, a switch structure slidably mounted on the center bead in an elastically reset manner, and a switch key for pushing the switch structure to slide within the center bead, the switch key being exposed on the surface of the center bead, the switch structure including a first avoidance groove, and the first avoidance groove including an unlocking surface and a snap-on surface arranged oppositely.

[0008] The bead assembly is connected to the second connection part of the adjacent bead assembly through the first connection part, and the switch structure locks the level pin assembled on the second connection part of the adjacent bead assembly and embedded in the first avoidance groove through the snap surface of the first avoidance groove under the action of the elastic reset force; the switch structure releases the level pin by the snap surface during the sliding process of the switch key pushing to overcome the elastic reset force, and the unlocking surface squeezes the level pin so that the level pin withdraws from the first avoidance groove, and there is an angle between the sliding direction of the switch structure and the withdrawal direction of the level pin.

[0009] In one embodiment, the center bead has a sliding groove, and the switch structure is installed in the sliding groove; the first connecting part has a first through hole connected to the sliding groove and used for the level needle to pass through, and the second connecting part has a second through hole coaxially arranged with the first through hole.

[0010] The first avoidance groove includes a hook portion having the buckle surface and an unlocking portion having the unlocking surface, and the first avoidance groove is located between the hook portion and the unlocking portion.

[0011] During the sliding process, the switch structure causes the hook portion to release the level pin embedded in the first avoidance groove through the first through hole and the second through hole, and the unlocking portion squeezes the level pin so that the level pin withdraws from the opening of the first avoidance groove, and the sliding direction of the switch structure is perpendicular to the withdrawal direction of the level pin.

[0012] In one embodiment, the unlocking portion has a curved surface or an inclined surface facing the hook portion.

[0013] One end of the level pin has a wave head and a hook groove is provided between the wave head and other parts of the level pin. The wave head of the level pin abuts and pushes the curved surface or inclined surface of the unlocking part to make the switch structure slide, and when the wave head enters the first avoidance groove, the switch structure hooks the hook groove of the level pin through the hook part under the action of the elastic reset force.

[0014] In one embodiment, the tail end face of the step needle is flush with the outer side face of the first side bead and / or the second side bead when the hook portion hooks the hook groove, and the tail end of the step needle protrudes from the outer side face of the first side bead and / or the second side bead when the wave head is pushed out of the first avoidance groove.

[0015] In one embodiment, a second avoidance groove is formed on the side of the sliding groove close to the second connecting portion relative to the surface of the center bead, and a first step portion is provided at the bottom of the switch key to match the second avoidance groove and to prevent the decorative part on the surface of the switch key from being scratched;

[0016] The switch structure slides in the sliding groove to separate the second avoidance groove from the first step portion, and at the same time drives the unlocking portion to squeeze the level pin so that the level pin withdraws from the opening of the first avoidance groove.

[0017] In one embodiment, the switch structure includes two first avoidance grooves, which are symmetrically arranged and connected in a back-to-back transition manner to form a transition connection portion.

[0018] The quick-release assembly further comprises an elastic member and a connecting member, wherein the head ends of the elastic member and the connecting member are both passed through the transition connection portion, and the tail ends thereof are respectively installed at the opposite ends of the sliding groove.

[0019] The switch structure adjusts the relative relationship between the elastic member and the connecting member during the sliding process, and the elastic member is squeezed by the connecting member when the buckle surface locks the level pin.

[0020] In one embodiment, the inner surface of the sliding groove on one side opposite to the first step portion has a boss for preventing the end of the connecting member from penetrating the wall of the sliding groove, and the other side has a protruding groove.

[0021] The switch structure further has a third avoidance groove for accommodating the boss and a fourth avoidance groove communicated with the protruding groove on both sides.

[0022] When the third avoidance groove is separated from the boss and the fourth avoidance groove covers the protruding groove, the connecting member and the elastic member switch from the squeezed state to the released squeezed state so that the buckle surface releases the level pin.

[0023] In one embodiment, the fourth avoidance groove covers the protruding groove to form a receiving chamber, and the elastic member is retained in the receiving chamber when the buckle surface releases the level pin.

[0024] In one embodiment, the number of the level pins is two; and both of the first avoidance grooves have the locking surface and the unlocking surface.

[0025] The two snap-fit surfaces lock the two second connecting parts respectively assembled on adjacent beaded assemblies through the two step pins; during the sliding process, the switch structure causes the two snap-fit surfaces to release the two step pins respectively, and the two unlocking surfaces squeeze the two step pins respectively so that the two step pins withdraw from the two first avoidance grooves respectively.

[0026] In one embodiment, it includes a watch dial and a watch strap as described in any one of the above items, and the end of the level needle has a handle for facilitating the removal of the level needle.

[0027] The beneficial effect of the present invention is that when the switch key in the watchband is pushed, the switch structure slides against the center bead, releasing the step pin on the unlocking surface, thereby separating two adjacent bead assemblies. This facilitates adding or removing some bead assemblies in the watchband to better match the size of the user's wrist. Furthermore, the aforementioned process is not only simple to operate, but also does not require any special disassembly or assembly tools. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] refer to Figure 1 The present invention provides a watch strap 1 pivotally connected to both ends of a watch dial, for a user to wear on the wrist to conveniently check the time in daily life. The watch comprises a watch dial and a watch strap 1. The ends of the watch strap 1 are pivotally connected to the two sides of the watch dial, so that the curve of the watch strap 1 can be adjusted to fit the curve of the user's wrist while the watch dial is placed directly above the user's wrist, thereby making it easier for the user to check the time on the watch.

[0042] refer to Figure 2 and Figure 3 Because the watchband 1 includes multiple bead assemblies 10, the length of the watchband 1 can be adjusted not only by adding or removing one or more bead assemblies 10, but also by simultaneously changing the angle between multiple adjacent bead assemblies 10 to adjust the curve of the watchband 1 (see above). Each bead assembly 10 includes a first side bead 101 on the left, a second side bead 102 on the right, and a center bead 103 pivotally connected between the first and second side beads 101, 102. Obviously, the line connecting the first and second side beads 101, 102 is perpendicular to the length of the watchband 1. The leading end of center bead 103 protrudes from the leading ends of first and second side beads 101, 102 in the same bead assembly 10, forming a first connecting portion 104. The trailing ends of first and second side beads 101, 102 protrude from the trailing end of center bead 103 in the same bead assembly 10, forming a second connecting portion 105. This facilitates interlocking or separating adjacent bead assemblies 10 by connecting or detaching the ends of first connecting portion 104 in each bead assembly 10 to or from the second connecting portion 105 of the adjacent bead assembly 10. Clearly, watchband 1 is formed by sequentially connecting a plurality of adjacent bead assemblies 10.

[0043] Continue to refer Figure 2 and Figure 3 The quick-release assembly 11 includes a level pin 110, a switch structure 111 slidably mounted on the center bead 103 in an elastically reset manner, and a switch key 112 for pushing the switch structure 111 to slide in the center bead 103. Specifically, the shape of the level pin 110 can be roughly shaft-shaped. In other embodiments, the shape of the level pin 110 is not limited. The level pin 110 sequentially passes through the second connecting portion 105 and part of the first connecting portion 104 and is embedded in the center bead 103 so that the first connecting portion 104 of the bead assembly 10 is locked with the second connecting portion 105 of the adjacent bead assembly 10. The switch key 112 is pushed to drive the switch structure 111 to slide in the center bead 103 so that the relative position of the level pin 110 and the second connecting portion 105 is adjusted, thereby separating the first connecting portion 104 of the bead assembly 10 from the second connecting portion 105 of the adjacent bead assembly 10. The switch key 112 is exposed on the surface of the center bead 103 so that the switch structure 111 can be driven to slide in the center bead 103 by pushing the switch key 112, thereby separating the adjacent bead assemblies 10 through the sliding of the switch structure 111 (see below for details). It should be noted that the surface of the switch key 112 is installed with a decoration for improving the ornamental value of the strap 1. In other embodiments, the surface of the switch key 112 may not be installed with a decoration. The switch structure 111 includes a first avoidance groove 1110. Specifically, the shape of the first avoidance groove 1110 can be roughly an oblique hook. In other embodiments, the shape of the first avoidance groove 1110 is not limited. It should be noted that as long as the shape of the first avoidance groove 1110 can achieve automatic hooking and releasing of the level needle 110 (see below for details), it should be within the scope of protection of this application. It should also be noted that when the relative position of the level needle 110 and the second connecting part 105 is adjusted, part of the level needle 110 will fall out of the first avoidance groove 1110. Obviously, referring to the above, the level pin 110 sequentially passes through the second connection portion 105 and a portion of the first connection portion 104 and is embedded in the first avoidance groove 1110, that is, the switch structure 111 is placed in the center bead 103 (see below for details). The first avoidance groove 1110 includes an unlocking surface 1112a and a snap-on surface 1111a that are arranged opposite to each other, so that the level pin 110 is locked by the snap-on surface 1111a so that the first connection portion 104 of the bead assembly 10 is locked with the second connection portion 105 of the adjacent bead assembly 10; or the level pin 110 is squeezed by the unlocking surface 1112a so that the level pin 110 is withdrawn from the first avoidance groove 1110, thereby separating the first connection portion 104 of the bead assembly 10 from the second connection portion 105 of the adjacent bead assembly 10.

[0044] refer to Figure 4In summary, the first connection portion 104 of the bead assembly 10 is connected to the second connection portion 105 of the adjacent bead assembly 10 via the positioning pin 110. Under the action of the elastic return force, the switch structure 111 locks the positioning pin 110, which is assembled on the second connection portion 105 of the adjacent bead assembly 10 and embedded in the first avoidance groove 1110, through the snap surface 1111a of the first avoidance groove 1110, thereby locking the first connection portion 104 of the bead assembly 10 with the second connection portion 105 of the adjacent bead assembly 10. When the switch structure 111 is pushed by the switch key 112 to overcome the elastic return force, the snap surface 1111a releases the positioning pin 110 during the sliding process, and the unlocking surface 1112a squeezes the positioning pin 110, causing it to withdraw from the first avoidance groove 1110. Furthermore, the withdrawal of the level pin 110 is achieved by the sliding of the switch structure 111 , so there is an angle between the sliding direction of the switch structure 111 and the withdrawal direction of the level pin 110 .

[0045] In one specific embodiment, the centering bead 103 has a sliding groove 1030, and the switch structure 111 is installed in the sliding groove 1030. Specifically, to enable the switch structure 111 to slide in the sliding groove 1030 in an elastically reset manner, the sliding groove 1030 is provided with one or more other structures, such as protrusions, steps, and grooves, resulting in an irregular shape. In other embodiments, the sliding groove 1030 can also be regular, for example, a rectangular parallelepiped. The first connecting portion 104 has a first through-hole 1040 that is connected to the sliding groove 1030 and is used for the positioning pin 110 to pass through. The second connecting portion 105 has a second through-hole 1050 that is coaxial with the first through-hole 1040. Since the positioning pin 110 is generally axial in shape, the shapes of the first through-hole 1040 and the second through-hole 1050 can both be circular. In other embodiments, the shapes of the first through-hole 1040 and the second through-hole 1050 are not limited. It should be noted that, since the first through hole 1040 is connected to the first avoidance groove 1110 through the sliding groove 1030, that is, the level pin 110 is sequentially inserted into the first avoidance groove 1110 through the second through hole 1050, the first through hole 1040 and part of the sliding groove 1030. Figure 5 and Figure 6 The first avoidance groove 1110 includes a hook portion 1111 having a latching surface 1111a and an unlocking portion 1112 having an unlocking surface 1112a. The hook portion 1111 and the unlocking portion 1112 respectively achieve their functions through the latching surface 1111a and the unlocking surface 1112a. The first avoidance groove 1110 is located between the hook portion 1111 and the unlocking portion 1112; in other words, the hook portion 1111 and the unlocking portion 1112 are transitionally connected to form the first avoidance groove 1110.

[0046] That is, during the sliding process, the switch structure 111 causes the hook portion 1111 to release the level pin 110 that is embedded in the first avoidance groove 1110 through the first through hole 1040 and the second through hole 1050, and the unlocking portion 1112, which slides under the drive of the switch structure 111, squeezes the level pin 110 so that the level pin 110 exits from the opening 1113 of the first avoidance groove 1110, so as to facilitate the separation of the first connection portion 104 of the bead assembly 10 from the second connection portion 105 of the adjacent bead assembly 10. It should be noted that the relative position of the level pin 110 and the second through hole 1050 is changed due to the withdrawal of the level pin 110 from the first avoidance groove 1110, and the second through hole 1050 is located at the second connection portion 105, that is, the withdrawal direction of the level pin 110 is the width direction of the center bead 103 and the first side bead 101 and the second side bead 102 arranged side by side on both sides of the center bead 103. However, the sliding direction of the switch structure 111 is the length direction of the center bead 103 , so the sliding direction of the switch structure 111 is perpendicular to the withdrawal direction of the level pin 110 .

[0047] In one specific embodiment, in order for the position pin 110 to push the unlocking portion 1112 and drive the switch structure 111 to slide so that the position pin 110 hooks onto the hook portion 1111 under the action of the elastic reset force, the unlocking surface 1112a on the unlocking portion 1112 should at least not be a plane. Therefore, the unlocking portion 1112 has a curved surface or an inclined surface facing the hook portion 1111, that is, the unlocking surface 1112a is a curved surface or an inclined surface; the position pin 110 has a wave head 1101 at one end. Specifically, the cross-sectional shape of the wave head 1101 can be semicircular. In other embodiments, the cross-sectional shape of the wave head 1101 is not limited. For example, the cross-sectional shape of the wave head 1101 can be rectangular. Since the wave head 1101 is assembled to the other parts of the stepped shaft-shaped level needle 110 to form the level needle 110, and the smaller diameter shaft section (based on the stepped shaft) is located between the wave head 1101 and the larger diameter shaft section (also based on the stepped shaft), and the size (diameter or radius) of the smaller diameter shaft section is smaller than the size (diameter or radius) of the wave head 1101, a hook groove is formed between the wave head 1101 and the other parts of the level needle 110. The wave head 1101 abuts and pushes the curved surface or inclined surface of the unlocking portion 1112 to slide the switch structure 111, and when the wave head 1101 enters the first avoidance groove 1110, the switch structure 111 hooks the hook groove of the level needle 110 through the hook portion 1111 under the action of the elastic reset force.

[0048] In one specific embodiment, when the hook portion 1111 is hooked into the hook groove, the tail end surface of the stepping pin 110 lies flush with the outer side surface of the first side bead 101 and / or the second side bead 102. At this point, the first connecting portion 104 of the bead assembly 10 is locked with the second connecting portion 105 of the adjacent bead assembly 10. Furthermore, when the wave head 1101 is pushed out of the first avoidance groove 1110, the tail end of the stepping pin 110 protrudes from the outer side surface of the first side bead 101 and / or the second side bead 102, forming a protruding portion 1100. In other words, the stepping pin 110 forms a stepping pin 110 relative to the first side bead 101 and / or the second side bead 102. At this point, the first connecting portion 104 of the bead assembly 10 is separated from the second connecting portion 105 of the adjacent bead assembly 10.

[0049] In one specific embodiment, a first step portion 1030a is formed on the side of the sliding groove 1030 near the second connecting portion 105 relative to the surface of the center bead 103, and a second avoidance groove 1114 is provided at the bottom of the switch structure 111 to match the first step portion 1030a and to prevent the decorative surface of the switch key 112 from being scratched. Obviously, the length direction of the first step portion 1030a and the second avoidance groove 1114 are both the width direction of the center bead 103. In other embodiments, the sliding groove 1030 may not have the first step portion 1030a, and the bottom of the switch structure 111 may not have the second avoidance groove 1114. It should be noted that as long as the switch structure 111 can slide in the sliding groove 1030, both the switch structure 111 and the sliding groove 1030 should be within the scope of protection of this application. Specifically, the switch structure 111 slides in the sliding groove 1030 to disengage the second avoidance groove 1114 from the first step portion 1030a, and at the same time drives the unlocking portion 1112 to squeeze the level pin 110 so that the level pin 110 withdraws from the opening 1113 of the first avoidance groove 1110, so as to facilitate the separation of the first connecting portion 104 of the bead assembly 10 from the second connecting portion 105 of the adjacent bead assembly 10.

[0050] In a specific embodiment, the switch structure 111 includes two first avoidance grooves 1110, so that the first connecting portion 104 of the bead assembly 10 and the second connecting portion 105 of the adjacent bead assembly 10 (referring to the above, the tail ends of the first side bead 101 and the second side bead 102 protrude from the tail end of the center bead 103 and form the second connecting portion 105, in other words, the first side bead 101 and the second side bead 102 both have a second connecting portion 105) are locked, that is, the first side bead 101 and the second side bead 102 of the bead assembly 10 are respectively pivotally connected to the two ends of the center bead 103 of the adjacent bead assembly 10. The two first avoidance grooves 1110 are symmetrically arranged and connected in a back-to-back transition to form a transition connection portion 1115, so as to facilitate the assembly of the elastic connecting piece 12112 so that the switch structure 111 can slide in an elastically reset manner to drive the snap portion to disengage from the groove 1102; or, the unlocking portion 1112 is pushed by the wave head 1101 and drives the switch structure 111 to slide so that the snap portion locks the groove 1102. It should be noted that the aforementioned process is the reset process of the switch structure 111 sliding in the sliding groove 1030 (it should be noted that the similarities and differences between the reset process of the switch structure 111 in the sliding groove 1030 and the sliding process of the switch structure 111 in the sliding groove 1030 mentioned above are that the same thing is that the form of movement is sliding, and the difference is that the relative position of the switch structure 111 or the switch key 112 and the sliding groove 1030 is different, which is specifically reflected in that when adjacent bead assemblies 10 are locked, the surface of the switch key 112 and the other parts of the surface of the median bead 103 relative to the sliding groove 1030 are on the same plane; when adjacent bead assemblies 10 are separated, the switch key 112 protrudes from the other parts of the surface of the median bead 103 relative to the sliding groove 1030), that is, the locking process of adjacent bead assemblies 10.

[0051] The quick-release assembly 11 also includes an elastic connector 12112 that allows the switch structure 111 to slide in the sliding groove 1030 in an elastically resilient manner. The elastic connector 12112 includes an elastic member 120 and a connector 121 that presses against the elastic member 120. Specifically, the elastic member 120 may be a spring, and the connector 121 may be a screw. In other embodiments, the structures of the elastic member 120 and the connector 121 are not limited. It is understood that any structure of the elastic member 120 and the connector 121 that allows the switch structure 111 to slide in the sliding groove 1030 in an elastically resilient manner is within the scope of protection of this application. The head ends of the elastic member 120 and the connector 121 are both inserted into the transition connection portion 1115, and their distal ends are respectively mounted at opposite ends of the sliding groove 1030, so that the latch portion can be released from the groove 1102 or locked into the groove 1102 during the sliding process of the switch structure 111 in the sliding groove 1030. It should be noted that the head ends of the elastic member 120 and the connecting member 121 respectively pass through the transition connection portion 1115 from both ends of the transition connection portion 1115 along the length direction of the transition connection portion 1115 (equivalent to the length direction of the center bead 103), and the length direction of the transition connection portion 1115 is also the sliding direction of the switch structure 111 in the sliding groove 1030, or the reset direction of the switch structure 111 sliding in the sliding groove 1030. Obviously, since the switch structure 111 slides in the sliding groove 1030 in an elastically reset manner, the switch structure 111 adjusts the relative relationship between the elastic member 120 and the connecting member 121 during the sliding process (the connecting member 121 is squeezed on the elastic member 120 or the connecting member 121 is released from the squeezing of the elastic member 120. It should be noted that the connecting member 121 and the elastic member 120 switch between the squeezed state and the released squeezed state, not because the connecting member 121 changes the motion state (the connecting member 121 is always in a stationary state relative to the center bead 103), but because the elastic member 120 is compressed or recovers its deformation during the sliding process of the switch structure 111. Please refer to the following for details), and the elastic member 120 is squeezed by the connecting member 121 when the snap surface 1111a locks the level needle 110.

[0052] refer to Figure 7In one embodiment, the inner surface of the sliding groove 1030 on the side opposite the first step 1030a has a boss 1030b for preventing the end of the connector 121 from penetrating the wall of the sliding groove 1030, and the other side has a protruding groove 1030c. The switch structure 111 also has a third avoidance groove 1116 on both sides for accommodating the boss 1030b and a fourth avoidance groove 1117 connected to the protruding groove 1030c. Specifically, the upper and lower groove walls of the protruding groove 1030c protrude from the groove wall surface of the sliding groove 1030, and when the connector 121 switches from the squeezed state to the released state, the protruding groove 1030c is inserted into the fourth avoidance groove 1117 (see below for details). Obviously, as the switch structure 111 slides within the sliding groove 1030, the connecting member 121 and the elastic member 120 switch between a squeezed and released state, and the relative relationships between the third avoidance groove 1116 and the boss 1030b, and between the fourth avoidance groove 1117 and the protruding groove 1030c, also change. More specifically, as the third avoidance groove 1116 disengages from the boss 1030b and the fourth avoidance groove 1117 covers the protruding groove 1030c, the connecting member 121 and the elastic member 120 switch from a squeezed to a released state, causing the latch surface 1111a to release the level pin 110, thereby facilitating the separation of adjacent beaded assemblies 10 during the sliding process of the switch structure 111.

[0053] In one embodiment, since the lower groove wall of the protruding groove 1030c abuts against the lower groove wall of the fourth avoidance groove 1117 when the protruding groove 1030c is embedded in the fourth avoidance groove 1117, and the upper and lower groove walls of the protruding groove 1030c and the left and right groove walls of the fourth avoidance groove 1117 are combined to form a chamber for accommodating the compressed spring, the fourth avoidance groove 1117 covers the protruding groove 1030c to form a accommodating chamber, and the elastic member 120 is retained in the accommodating chamber when the snap surface 1111a releases the level pin 110.

[0054] In one embodiment, there are two level pins 110; correspondingly, the two first avoidance grooves 1110 each have a snap-on surface 1111a and an unlocking surface 1112a. The two snap-on surfaces 1111a lock the two second connecting portions 105 respectively assembled on adjacent bead assemblies 10 through the two level pins 110, thereby locking the adjacent bead assemblies 10; during the sliding process, the switch structure 111 causes the two snap-on surfaces 1111a to release the two level pins 110 respectively, and the two unlocking surfaces 1112a respectively squeeze the two level pins 110 so that the two level pins 110 exit from the two first avoidance grooves 1110, thereby separating the adjacent bead assemblies 10.

[0055] In one embodiment, the end of the level pin 110 has a handle 1103 for facilitating the removal of the level pin 110. Obviously, the size of the handle 1103 (e.g., diameter or radius) is larger than or slightly larger than the size of the main part of the level pin 110 (e.g., diameter or radius).

[0056] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
