The other is an integrated strap made of soft materials such as leather and rubber. The most common one is a metal strap. In addition, there is a leather strap. Metal straps are formed into a belt shape by connecting several strap particles in series through steel needles.

[0003] For example, the magnetic watchband technology disclosed in Chinese patents ZL2022232748088, ZL202223274843X, and ZL2024200902724 (all applied for by the present creator) all disclose that the watchband body is composed of several connecting parts connected in series, and the two ends of the watchband body are respectively provided with a head particle and a tail particle, and the watchband body is also sleeved with a middle particle, and a magnetic block that can be adsorbed on the watchband body is set on the tail particle, thereby realizing the wearing of the watch. The above-mentioned magnetic watchbands all need to be provided with a metal connecting part that can adsorb the magnetic block, or add a layer of metal powder on the surface of the watchband body to make it have the property of adsorbing with the magnetic block. If it is made of lightweight metal materials such as aluminum alloy and titanium alloy, the magnetic attraction effect cannot be achieved, and the versatility is poor. If a layer of metal powder is added to lightweight metal materials such as aluminum alloy and titanium alloy, the cost is increased.

In specific applications, after the wearable device is worn on the wrist through the strap 2000, the wearable device can be firmly worn on the wrist by locking the loop clasp; after the locking state of the loop clasp is released, the wearable device can be removed from the wrist; the loop clasp includes a clasp body 1000 and a strap 2000, one end of which can be buckled with the clasp body 1000 and the other end of which can be quickly connected to the clasp body 1000; the strap 2000 is composed of a plurality of connecting parts 2001 connected in series, and a head particle 2002 and a strap end 6 are respectively provided at both ends of the strap 2000, and a middle particle 2003 is also sleeved on the strap 2000, the head particle and the middle particle are respectively connected to the corresponding wearable devices such as watches and bracelets, the strap end 6 is connected to the clasp body 1000, and the clasp body 1000 can be snapped into any position of the strap 2000.

[0033] Specifically, in this embodiment, the buckle body 1000 is mainly used for buckling and detaching the strap 2000. In order to realize the buckling and detaching connection of the strap 2000, for this purpose, Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the buckle body 1000 includes a cover plate 1, a first slider 2, a second slider 3 and a pressure cover 4 which are slidably arranged in the cover plate 1. The cover plate 1 is provided with a receiving groove 10 along the length direction. A pressure cover positioning groove 11 is provided in the receiving groove 10 along the width direction of the cover plate 1. A slide groove 12 which is arranged along the width direction and can slide the first slider 2 and the second slider 3 is opened in the pressure cover positioning groove 11. The two ends of the slide groove 12 are provided with limit platforms 13 which are respectively used to limit the sliding distance of the first slider 2 and the second slider 3. The pressure cover 4 is provided with a On the pressing cover positioning groove 11, the pressing cover 4 is covered with a sliding groove 12, and both ends are locked on the corresponding limit platforms 13. When the watch strap 2000 needs to be locked, the watch strap 2000 is pressed into the accommodating groove 10, so that the watch strap 2000 pushes the first slider 2 and the second slider 3 outward. When the watch strap 2000 is pressed into the accommodating groove 10, the first slider 2 and the second slider 3 are reset without the downward pressure of the watch strap 2000, and the watch strap 2000 is clamped to achieve locking.

[0034] Furthermore, the first slider 2 and the second slider 3 are mainly used for clamping the watch band 2000, and can slide in the slide groove 12 and automatically reset. To this end, in the present embodiment, the first slider 2 and the second slider 3 are both provided with a pressing portion 20, a sliding portion 21 and a buckling portion 22. The sliding portion 21 is slidably arranged in the slide groove 12, and the sliding portion 21 can slide through the limit platform 13 to connect with the pressing portion 20. The buckling portion 22 is arranged at the other end of the sliding portion 21, and asymmetric guide openings are respectively provided on the two limit platforms 13. The sliding portions 21 on the first slider 2 and the second slider 3 respectively pass through the guide openings on the two limit platforms 13. Two elastic members 7 are provided between the platform 13 and the pressing portion 20. The two elastic members 7 are symmetrically arranged on both sides of the pressing portion 20, and the pressing portion 20 is correspondingly provided with mounting holes for installing the elastic members 7. In this embodiment, the elastic member 7 adopts a spring. The elastic member 7 can keep the two buckling portions 22 and the gap between the two adjacent connecting members 2001 of the strap 2000 in a free state; the two pressing portions 20 are pushed by an external force to push the sliding portion 21 to move along the slide groove 12, driving the two corresponding buckling portions 22 to move in opposite directions, so that the two buckling portions 22 are respectively disengaged from the gap between the two adjacent connecting members 2001, and the buckling state with the strap 2000 can be released.

[0035] That is to say, when there is no force acting on the elastic member 7, the elastic member 7 always maintains the force, pushes the pressing portion 20 outward, and at the same time pulls the buckling portions 22 on the first slider 2 and the second slider 3 to move away from each other and gradually approach each other, so that the accommodating groove 10 is reduced, and the two buckling portions 22 are kept engaged with the gap between the two connecting members 2001 adjacent to the strap 2000, and the state of being engaged with the strap 2000 is always maintained; when the force is applied to the pressing portion 20, the pressing portion 20 pushes the sliding portion 21 to drive the buckling portion 22 to move, so that the buckling portions 22 on the first slider 2 and the second slider 3 move away from each other and gradually move away, so that the accommodating groove 10 is increased, and the two buckling portions 22 are separated from the gap between the two connecting members 2001 adjacent to the strap 2000, the locking state of the loop buckle is released, and then the state of being engaged with the strap 2000 is released.

[0036] In one embodiment, if Figure 7The slide groove 12 includes a small diameter section 120 extending along the width direction of the cover plate 1 and a large diameter section 121 arranged at both ends of the small diameter section 120. The small diameter section 120 and the large diameter section 121 are arranged to play a guiding role. The sliding parts 21 of the first slider 2 and the second slider 3 are slidably arranged back to back on the small diameter section 120. The limit platform 13 is respectively arranged on the two large diameter sections 121, and the large diameter section 121 is divided into an outer diameter end and an inner diameter end. The pressing part 20 is movably located at the outer diameter end, and part of it is outside the outer diameter end. This arrangement is convenient The pressing part 20 is pressed and slides along the outer diameter end, and the buckling part 22 is movably located at the inner diameter end, and the two sliding parts 21 pass through the limit platform 13 and the buckling part 22 correspondingly; it should be noted that the buckling part 22 of the first slider 2 is located in the inner diameter end close to one end of the pressing part 20 of the second slider 3, and the buckling part 22 of the second slider 3 is located in the inner diameter end close to one end of the pressing part 20 of the first slider 2, so that when the pressing part 20 is pressed, the buckling parts 22 on the first slider 2 and the second slider 3 move in opposite directions.

[0037] Furthermore, if Fig.10 The buckle part 22 is mainly used to snap into the gap between two adjacent connecting members 2001 of the strap 2000. The buckle part 22 includes a support part 220 connected to the sliding part 21, a clamping strip 221 provided on the support part 220 and on one side of the sliding part 21, and a hook part 222 provided on the top of the support part 220. The clamping strip 221 is vertically provided on the support part 220, and the upper surface of the hook part 222 is inclined. The support part 220, the clamping strip 221 and the hook part 222 are integrated. The pressing part 20, the sliding part 21 and the buckle part 22 are integrated. The clamping strip 221 is snapped into the gap between two adjacent connecting members 2001 of the strap 2000, and the hook part 222 is clamped on the strap 20 00 surface, a guide block 223 sliding along the inner diameter end is provided at the bottom of the support portion 220, and a sliding opening 224 for the sliding portion 21 to pass through is provided on the support portion 220 on the side of the guide block 223. When the strap 2000 needs to be locked, the strap 2000 is pressed into the receiving groove 10, so that the strap 2000 pushes the hook portion 222, so that the two buckling portions 22 are stretched outward. When the strap 2000 is pressed into the receiving groove 10, the hook portion 222 is not under pressure, so that the elastic member 7 pushes the pressing portion 20 to pull the sliding portion 21 to drive the buckling portion 22 to reset, thereby allowing the clamping strip 221 to be inserted into the gap between the two adjacent connecting members 2001 of the strap 2000 to achieve clamping.

[0038] In order to enable the buckle portion 22 to continue to move and achieve the effect of snap connection after the gland 4 is installed, the main structure of the gland 4 is as follows: Fig.11The pressure cover 4 includes a pressing portion 40, and connecting portions 41 arranged on both sides of the pressing portion 40 and fixedly connected to the limiting platform 13 respectively. The connecting portion 41 and the pressing portion 40 are in a vertical state.

The extending portion 43 A connecting hole 44 is provided, and the limit platform 13 is provided with a fixing hole corresponding to the connecting hole 44. The pressure cover 4 is threadedly connected to the connecting hole 44 on the limit platform 13 by screws passing through the connecting hole 44, thereby fixing the pressure cover 4 on the limit platform 13; in addition, the thickness of the sliding part 21 is less than the height of the slide groove 12, and the thickness of the clamping part 40 is consistent with the height of the cover positioning groove, thereby allowing the sliding part 21 to slide back and forth along the slide groove 12, while keeping the clamping part 40 and the surface of the cover positioning groove in the same plane to avoid affecting the wearing due to the protrusion, thereby ensuring the comfort when wearing.

[0039] like Fig. 9 and Fig.12 In order to quickly replace and install the watch strap 2000, a rotating buckle assembly 5 is provided in the present application. Specifically, a quick release slot 14 is provided at the end of the cover plate 1. Rotating buckle assemblies 5 for locking the watch strap end 6 are provided on both sides of the quick release slot 14. The two rotating buckle assemblies 5 are symmetrically arranged on the quick release slot 14. During installation, when the watch strap end 6 is inserted into the quick release slot 14, the rotating buckle assembly 5 is pushed to rotate along the quick release slot 14. After the watch strap end 6 is inserted into the bottom of the quick release slot 14, the two rotating buckle assemblies 5 rotate to engage the watch strap end 6. During disassembly, the two rotating buckle assemblies 5 are simultaneously moved to rotate along the quick release slot 14 to disengage the two rotating buckle assemblies 5 from the watch strap end 6, so that the engaging state with the watch strap end 6 can be released. The watch strap 2000 is pulled to disengage the watch strap end 6 from the quick release slot 14 to achieve disassembly.

[0040] Specifically, the rotating buckle assembly 5 includes a buckle 50, an elastic reset member 51 connected to the buckle 50 and with one end abutting against the inner side edge of the quick-release slot 14, and a blocking portion 52 formed on both sides of the quick-release slot 14 and used to limit the rotation angle of the buckle 50; in this embodiment, the elastic reset member 51 is a spring; that is, when the elastic reset member 51 is in a free state, the elastic reset member 51 pushes one end of the buckle 50 to contact the blocking portion 52, and at the same time, the buckle 50 is clamped on the strap end 6 to lock the strap end 6; when the buckle 50 is rotated, one end of the buckle 50 moves away from the blocking portion 52, the buckle 50 is detached from the strap end 6, and the other end of the buckle 50 is blocked by the blocking portion 52, and the strap end 6 is unlocked to achieve disassembly.

[0041] The buckle 50 includes a rotating buckle portion 501, a toggle portion 502 having one end connected to the rotating buckle portion 501 and the other end extending to the outside of the quick release slot 14, and a shaft 503 rotatably connected to the rotating buckle portion 501, one end of the shaft 503 passes through a side wall of the quick release slot 14, and a toggle slot 15 for the movement of the toggle portion 502 is provided on the side wall of the quick release slot 14 located at the blocking portion 52, and the toggle slot 15 is provided to facilitate the movement of the moving portion, and an angle is formed between the rotating buckle portion 501 and the toggle portion 502, and the angle is set in a range of 95-115 degrees, so as to facilitate the rotation of the toggle rotating buckle portion 501, and the rotating buckle portion 501 is provided with a mounting portion 504 connected to the elastic reset member 51, and an angle is formed between the mounting portion 504 and the rotating buckle portion 501, and the angle is set in a range of 85 degrees to 95 degrees;

[0042] In addition, correspondingly, both sides of the strap end 6 are provided with a locking groove 60 adapted to the rotating buckle part 501, and the locking groove 60 is provided with a convex part 61 engaged with the rotating buckle part 501, and the contact end surface of the convex part 61 and the rotating buckle part 501 is an inclined surface. When the strap 2000 needs to be installed, the strap end 6 is inserted into the quick release slot 14. When the strap end 6 is pushed into the quick release slot 14, the strap end 6 contacts the rotating buckle part 501 and pushes the rotating buckle part 501 to rotate. When the strap end 6 is inserted to the bottom of the quick release slot 14, the rotating buckle part 501 is located in the locking groove 60. Since the rotating buckle part 501 has no force, it is pushed to reset by the elastic reset member 51, so that the rotating buckle part 501 It is clamped with the protrusion 61. Since the blocking portion 52 blocks the toggle portion 502, the rotating buckle portion 501 cannot continue to rotate out of the quick-release slot 14. Therefore, when the strap 2000 is pulled, the strap 2000 will not be separated from the quick-release slot 14, so as to realize the quick installation function of the strap 2000; when the strap 2000 needs to be removed, the toggle portion 502 is moved along the outside of the toggle slot 15 to rotate the rotating buckle portion 501. The rotating buckle portion 501 slides and separates from the protrusion 61 through the inclined surface of the protrusion 61. When one end of the rotating buckle portion 501 contacts the blocking portion 52, the rotating buckle portion 501 is completely separated from the protrusion 61, so that the end portion 6 of the strap can be pulled out of the quick-release slot 14 to realize the quick removal function.

[0043] In one embodiment, a positioning convex strip 16 extending from the slot opening into the slot is formed on one of the inner side walls of the quick-release slot 14, and a guide slide 62 matching the positioning convex strip 16 is provided on the strap end 6. This arrangement enables the strap end 6 to be smoothly inserted into the quick-release slot 14, and prevents the strap end 6 from loosening or shaking left and right after being locked, thereby ensuring wearing comfort.

[0044] In summary, the present application provides a first slider 2 and a second slider 3 on the clasp body 1000 to be slidably engaged in the gap between the two adjacent connecting members 2001 of the strap 2000, and provides a limit platform 13 on both sides of the slide groove 12 to limit the sliding movement distance of the first slider 2 and the second slider 3, and an elastic member 7 is provided between the corresponding limit platforms 13 of the first slider 2 and the second slider 3. The elastic member 7 can keep the two buckling parts 22 engaged with the gap between the two adjacent connecting members 2001 of the strap 2000 in a free state; the two pressing parts 20 are pushed by an external force to push the sliding part 21 to move along the slide groove 12, driving the two corresponding buckling parts 22 to move in opposite directions, so that the two buckling parts 22 are respectively separated from the gap between the two adjacent connecting members 2001, and the engagement state with the strap 2000 can be released, and then the loop clasp can be engaged with the strap 2000 in a non-magnetic state to realize the wearing of the watch. In combination with the above-mentioned loop buckle structure, a rotating buckle assembly 5 is provided for quickly installing and removing the strap 2000. By opening a quick release slot 14 at the end of the cover plate 1, and arranging rotating buckle assemblies 5 on both sides of the quick release slot 14, when the strap end 6 is inserted into the quick release slot 14, the rotating buckle assembly 5 is pushed to rotate along the quick release slot 14. After the strap end 6 is inserted into the bottom of the quick release slot 14, the two rotating buckle assemblies 5 rotate so that the two rotating buckle assemblies 5 are engaged with the strap end 6 to achieve a quick installation effect; when the two rotating buckle assemblies 5 are rotated by force, the two rotating buckle assemblies 5 are separated from the strap end 6, and the engaged state with the strap end 6 can be released.
