Description

Technical Field

[0001] This invention relates to the field of watch technology, specifically to a magnetically connected watch strap. Background Technology

[0002] As a personal accessory that combines timekeeping and decorative functions, the design of a watch strap directly affects its comfort, convenience, and overall aesthetics. Traditional watch straps come in various connection methods, such as pin buckles, folding buckles, and push-button buckles. These methods typically require users to perform a series of operations, such as aligning the holes, inserting, pressing, or folding, to put on or remove the watch. This process is relatively cumbersome and provides a poor experience for users who operate the watch with one hand or have limited hand mobility.

[0003] In existing technology, watch straps are typically designed with detachable links to facilitate length adjustment for different wrist sizes. However, the adjustment process often requires the use of special tools to remove the connecting pins, which is complex and carries the risk of damaging the strap or losing small parts. Another common adjustment method involves multiple fixing holes at the clasp, but this method has limited adjustment precision, making it difficult to achieve a perfect fit, and long-term use may cause wear and tear on the leather or materials at the clasp holes.

[0004] Furthermore, some modern designs employ magnetic attraction for quick strap connection. While this improves wearing speed, it often relies solely on magnetic adhesion, resulting in insufficient connection stability. Pure magnetic connections are prone to accidental separation under external pulling or vigorous movement, posing a risk of the watch falling off, and their reliability needs improvement. Simultaneously, while existing magnetic straps offer quick connection, they often lack effective integration with convenient and precise length adjustment mechanisms or flexible adaptable structures, making it difficult to simultaneously meet multiple needs such as quick wearing, secure locking, comfortable fit, and personalized customization. Summary of the Invention

[0005] The purpose of this invention is to provide a magnetically connected watch strap to improve the applicability of the strap and solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a magnetically connected watch strap, comprising a first strap composed of detachable first links and a second strap composed of second links. The first link has a control cavity, and retractable connecting rods and perforated connectors are respectively provided on both sides. Adjacent links are rotatably connected by inserting the connecting rods and the connectors. An exposed control plate is movably disposed on the first link, which is connected to a pressing member disposed in the cavity. The pressing member controls its extension and retraction by pushing the inclined block on the connecting rod, so as to realize the disassembly and assembly of the first link and the length adjustment of the first strap. The front of the first link has a buckle groove with a steel plate embedded in it, and the sides of the groove have inserts that can slide laterally and are held by elastic elements. The end of the second strap is provided with an end seat, which is movably connected to a fastener with a connector; The connector has a floating seat with a magnetic block inside, which can move along the guide rod. The inner wall of the connector has a slot. When the connector is attracted to the slot, the floating seat presses down and pushes the insert block outward to insert into the slot, forming a dual connection of magnetic attraction and mechanical locking. The connector also has a pulling structure for the floating seat. A fine-tuning mechanism is provided between the end seat and the fastener, including a knob and an adjustment actuator connected to it. The actuator adjusts the relative position of the fastener and the end seat or the elastic force of the elastic connection component between them by rotating the knob.

[0007] Preferably, the control plate is fixedly connected to the bottom of the pressure piece via a slider, and the bottom of the control cavity is provided with a toothed groove; The slider is slidably positioned within the toothed groove, and the inner wall of the toothed groove generates frictional resistance to the movement of the slider.

[0008] Preferably, the pressure piece has a U-shaped structure, with its inner walls on both sides contacting and fitting with the inclined surface of the inclined block; The connecting rod is fixed on the sliding rod, the inclined block is set on the sliding rod, the sliding rod is limited and slidably installed in the guide groove in the control cavity, and a first spring is connected between the two sliding rods.

[0009] Preferably, the insert is I-shaped, and its inner side is elastically connected to the groove wall of the snap-fit ​​groove through a rubber pad, which provides elastic force to keep the insert retracting inward.

[0010] Preferably, the floating seat is movably installed inside the connector via a guide rod, and a magnetic block is embedded in the floating seat, giving the floating seat a magnetic attraction function and allowing it to float up and down relative to the connector.

[0011] Preferably, the pulling structure includes a lever rotatably mounted on the top of the connector and a suspension rope connecting the lever and both sides of the top of the floating seat. Rotating the lever can lift the floating seat upwards via the suspension rope.

[0012] Preferably, the adjustment actuation component of the fine-tuning mechanism includes a first gear coaxially connected to the knob, a first rack fixedly connected to the fastener, and a movable shaft seat; The bearing seat is linked to the knob and can drive the first gear to move, so that it has a locked position that is disengaged from the first rack and an adjustable position that is engaged with the first rack; the bearing seat is provided with a stop bar that can be inserted into the tooth gap of the first rack.

[0013] Preferably, the adjustment actuation component of the fine-tuning mechanism includes a second gear that is connected to the knob via a bevel gear pair, a second rack that meshes with the second gear, and a side seat that is fixedly connected to the second rack; A plug is mounted on the side seat; the flexible connection assembly includes multiple rubber cords arranged side by side.

[0014] Preferably, a second spring is also connected between the fastener and the end seat, and the insert rod can be selectively inserted into different numbers of rubber ropes to change the effective number of rubber ropes that work together with the fastener and the end seat, thereby adjusting the overall elasticity.

[0015] Preferably, on the same first link, the connecting rod and the connector are staggered in the length direction of the link.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention provides a watch strap that is highly efficient to wear, securely connected, flexibly adjustable, comfortable, and durable through an innovative combination of magnetic attraction and mechanical locking, multi-level length adjustment, and a flexible structural design. It enables quick, convenient, and stable connection and disassembly of the strap. The magnetic structure achieves initial alignment and attraction; the user simply brings the two ends close together for automatic alignment and connection, significantly improving wearing efficiency. After attraction, the floating seat pushes the insert block out and locks it into the slot of the connector, forming a second mechanical lock, effectively preventing accidental disengagement due to external force or movement, ensuring high reliability of the connection.

[0017] 2. This invention provides flexible and precise length adjustment capabilities. Users can easily add or remove the first link to coarsely adjust the overall length of the strap to accommodate different wrist sizes. Furthermore, a fine adjustment of the length or elasticity can be made through a micro-adjustment mechanism within the end mount, ensuring the strap perfectly fits the wrist while providing a comfortable tightness to meet individual wearing needs.

[0018] 3. The structure of this invention balances strength, lightweight design, and ease of user operation. A double support beam is installed inside the first link to enhance structural strength and prevent deformation. The control mechanism employs a combination of wedges, pressure components, and springs, generating frictional resistance through toothed grooves. This ensures smooth adjustment while preventing accidental slippage during daily use. The entire adjustment process can be easily completed externally without tools, providing a user-friendly experience.

[0019] 4. This invention achieves a balance between wearing comfort and functionality. Through the combination of springs and rubber cords, the watch strap possesses a certain degree of elasticity and flexibility, adapting to the subtle deformations of the wrist during activity and reducing pressure and the feeling of foreign objects.

[0034] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 13 The present invention provides a technical solution: a magnetically connected watch strap, which can be stably and quickly fastened by magnetic attraction, and its length can be freely adjusted to suit different users.

[0036] The watch strap includes a detachable and adjustable first strap and a second strap with a buckle. The first strap is composed of interconnected first links 1, while the second strap is composed of interconnected second links 2. Telescopic connecting rods 3 are provided on both sides of the first link 1, and connectors 4 with holes are fixedly installed on both sides of the first link 1. The connecting rods 3 and connectors 4 on the same first link 1 are staggered. Therefore, adjacent first links 1 can be assembled to form a complete first strap by rotating the connecting rods 3 and connectors 4. The length of the first strap can be changed by disassembling and installing the first links 1 as needed.

[0037] The second link 2 is also provided with connectors 4 on both sides, and adjacent second links 2 can be rotatably connected through connectors 4. However, the second strap adopts a non-removable structure and has a fixed length.

[0038] Furthermore, both the first and second watch straps are provided with spring bars 5 at their ends for connecting to the lugs on the watch case, thus connecting the first and second watch straps to both sides of the watch case.

[0039] The first link 1 has a hollow structure and a control cavity 6. A vertical first support beam 7 and a second support beam 8 are welded and fixed inside the control cavity 6 to reinforce it and prevent deformation. The first support beam 7 and the second support beam 8 are arranged side by side. The second support beam 8 is provided with a guide groove 9. Two sliding rods 10 are slidably installed in the guide groove 9. The two sliding rods 10 are symmetrically arranged, and the two connecting rods 3 of the first link 1 are welded and fixed to the two sliding rods 10 respectively. By moving the sliding rods 10, the connecting rods 3 can be extended and retracted. At the same time, a first spring 11 is connected between the two sliding rods 10 by a pin. The elastic force of the first spring 11 can pop out the two connecting rods 3 and connect them with the connecting piece 4 of the first link 1.

[0040] The first link 1 is also equipped with a control structure for the slide rod 10 and the connecting rod 3, used to drive the connecting rod 3 to extend and retract. A U-shaped pressure member 13 is slidably installed in the control cavity 6, and an inclined block 12 is fixedly installed on the slide rod 10. The pressure member 13 can contact and connect with the inclined block 12. The movement of the pressure member 13 can push the inclined block 12, thereby driving the slide rod 10 and the connecting rod 3 to move. A slider 14 is welded and fixed to the bottom of the pressure member 13, and a control plate 15 is welded and fixed to the slider 14. The bottom of cavity 6 is provided with a toothed groove 16, and the slider 14 is slidably installed in the toothed groove 16. The control plate 15 is set against the bottom surface of the first link 1. The control plate 15 can drive the pressure member 13 to move in the control cavity 6, thereby controlling the extension and retraction of the docking rod 3 from the outside, which facilitates the disassembly and installation of the first link 1 and the adjustment of the length of the first watch strap. The inner wall of the toothed groove 16 can generate resistance to the slider 14. Combined with the elastic force of the first spring 11, it can prevent the control plate 15 from moving accidentally and affecting the stability of the first watch strap.

[0041] Furthermore, a slot 17 is provided in the first link 1, and a steel sheet 18 is installed in the first link 1 by using the slot 17, and its ferromagnetism serves as the basis for magnetic adsorption.

[0042] A buckle groove 19 is provided at the center of the front of the first link 1. I-shaped inserts 20 are slidably installed on both sides of the buckle groove 19. An elastic rubber pad 21 is connected between the insert 20 and the groove wall of the buckle groove 19. The elasticity of the rubber pad 21 can make the insert 20 retract into the buckle groove 19.

[0043] An end seat 22 is fixedly installed on the second link 2 at the end of the second watch strap. An adjustable buckle 23 is movably installed on the end seat 22. A connector 24 is fixedly installed on the buckle 23 by screws. The connector 24 on the buckle 23 can magnetically connect with the buckle slot 19, thereby quickly connecting the first watch strap and the second watch strap together and putting it on the user's wrist.

[0044] The connector 24 is a square cap-shaped structure that can be fastened onto the buckle groove 19. A guide rod 25 is welded and fixedly installed in the connector 24. A floating seat 26 is movably installed in the connector 24 via the guide rod 25. A magnetic block 27 is embedded in the floating seat 26, so the floating seat 26 has magnetic force and can be attracted into the buckle groove 19, playing a preliminary attraction and connection role. At the same time, since the floating seat 26 can move, when it is attached to the buckle groove 19, it can push the insert 20 and make it pop out of the buckle groove 19. A slot 28 is provided on the inner wall of the connector 24. When the insert 20 pops out of the buckle groove 19, it can be inserted into the slot 28, further fixing the connector 24 and the buckle groove 19 together. Only when the floating seat 26 is lifted can the insert 20 retract, separating the connector 24 from the buckle groove 19, completing the separation of the first watch strap and the second watch strap.

[0045] The top surface of the floating seat 26 is fixedly connected to both sides of the suspension rope 29. The other end of the suspension rope 29 passes through the top surface of the connector 24 and is connected to both ends of a lever 30. The lever 30 is rotatably mounted on the top surface of the connector 24. By rotating the lever 30, the suspension rope 29 can be pulled to overcome the magnetic force and lift the floating seat 26, thereby causing the insert block 20 to retract.

[0046] The end seat 22 and the fastener 23 of the present invention are connected in a movable manner. When the first watch strap and the second watch strap are connected and the number of the first links 1 is determined, the length of the first watch strap can be finely adjusted by the movement of the fastener 23 to better meet the needs of the user. A rotating shaft 31 is rotatably installed in the end seat 22, and a knob 32 is fixedly installed at the end of the rotating shaft 31. The knob 32 is located on the side of the end seat 22. By rotating the knob 32, the length of the first watch strap can be adjusted. Example

[0047] The other end of the rotating shaft 31, which extends into the end seat 22, is fixedly equipped with a first gear 33. The part of the fastener 23 inserted into the end seat 22 is fixedly connected to a first rack 34. The middle part of the rotating shaft 31 is rotatably mounted in a bearing 35, and the bearing 35 can move with the rotating shaft 31. The bearing 35 is slidably mounted in the bottom guide groove of the end seat 22. A stop bar 36 is fixedly mounted on the bearing 35. Under normal conditions, when the knob 32 is pressed against the outer wall of the end seat 22, the stop bar 36 on the bearing 35 can be inserted. The first rack 34 is blocked in the gap, thus fixing the position of the fastener 23 in the end seat 22. When adjustment is needed, the knob 32 is pulled away from the end seat 22, and the rotating shaft 31, the bearing 35 and the first gear 33 can move accordingly. At this time, the stop bar 36 disengages from the first rack 34, and the first gear 33 meshes with the first rack 34. By rotating the knob 32, the first rack 34 can be driven to adjust the overall length of the fastener 23 and the end seat 22, thereby completing the fine adjustment work. Example

[0048] The rotating shaft 31 is rotatably mounted in the end seat 22 using a retaining ring and a shoulder, so that it can only rotate and cannot be pulled axially. A second gear 38 is rotatably mounted in the end seat 22 via a wheel and axle, and the wheel and axle are connected to the rotating shaft 31 by a bevel gear pair 37. Therefore, rotating the knob 32 can drive the rotating shaft 31, the wheel and axle, and the second gear 38 to rotate. The second gear 38 meshes with the second rack 39, and the end of the second rack 39 is fixedly connected to the side seat 40. The side seat 40 is slidably mounted in the straight groove of the end seat 22. Therefore, rotating the knob 32 can drive the side seat 40 to move. A plug rod 41 is fixedly mounted on the side seat 40 by screws.

[0049] Furthermore, the portion of the buckle 23 inserted into the end seat 22 is connected to a second spring 42 via a pin, and the other end of the second spring 42 is fixedly connected to the end seat 22 via a pin. Therefore, it can generate elastic force to connect the buckle 23 and the end seat 22, allowing the first watch strap to elastically stretch and adapt to the user's wrist. At the same time, the portion of the buckle 23 that extends into the end seat 22 is equipped with a looped rubber cord 43. By rotating the knob 32, the side seat 40 is moved, allowing the insert 41 to be inserted into different numbers of rubber cords 43, thereby connecting different numbers of rubber cords 43 between the buckle 23 and the end seat 22 to adjust the elasticity and meet the user's requirements for the tightness of the first watch strap.

[0050] In use, the invention works as follows: First, based on the user's wrist size, the control plate 15 moves the pressure member 13, pushing the inclined block 12 to compress the slide rod 10, which in turn retracts the connecting rod 3. This allows the first link 1 to be removed or added, thus quickly adjusting the overall length of the first watch strap. Subsequently, the first and second watch straps are respectively installed on both sides of the watch case via spring bars 5.

[0051] When wearing the watch, align the buckle slot 19 at the end of the first strap with the connector 24 on the second strap end seat 22. The magnet 27 inside the floating seat 26 attracts the steel piece 18 inside the buckle slot 19, achieving initial magnetic alignment. After attraction, the floating seat 26 presses down, pushing the insert 20 outward against the elasticity of the rubber pad 21, and inserts it into the slot 28 of the connector 24, forming a mechanical lock to ensure a secure connection.

[0052] If you need to fine-tune the tightness of the watch strap, you can choose the adjustment method according to the example: In Embodiment 1, the knob 32 is pulled outward to disengage the stop bar 36 from the first rack 34. The knob 32 is rotated to drive the first rack 34, which in turn moves the fastener 23 and the connector 24 to achieve a fine adjustment of the length. Then, the knob 32 is pushed back to lock the stop bar 36 in place.

[0053] In embodiment 2, the knob 32 is turned directly, which drives the second gear 38 to rotate through the bevel gear pair 37, thereby driving the second rack 39 and the side seat 40 to move, so that the insert 41 is inserted into the corresponding number of rubber cords 43, adjusting the elasticity and thus changing the elasticity of the watch strap.

[0054] During disassembly, rotate lever 30 to lift floating seat 26 via suspension rope 29. The magnetic attraction weakens and insert 20 retracts into buckle groove 19 under the action of rubber pad 21, making it easy to separate connector 24 from buckle groove 19 and untie watch strap.

[0055] Therefore, this invention achieves convenient wearing, stable connection and flexible adaptation of watch straps by combining magnetic quick alignment, mechanical locking reinforcement, adjustable links and elastic fine adjustment.
