Description

Technical Field

[0001] The utility model belongs to the technical field of watch accessories, and in particular relates to a watch buckle structure and a watch strap. Background Art

[0002] A watch is a common portable timing instrument that requires a strap to be worn, and a clasp is a key component for achieving the strap connection.

[0003] Most traditional watch buckles are inconvenient to operate, so magnetic watch buckles have appeared on the market. For example, the utility model patent with application number 2023230811742 mentions a new watch strap buckle, which mainly includes a first fastener and a second fastener. The first fastener is fixed to the watch strap and is provided with a first magnetic part. The second fastener is mounted on the watch strap and is provided with a first magnetic part. Through the magnetic cooperation of the first magnetic part and the second magnetic part, the watch can be worn, and the user experience is better.

[0004] However, in actual use, it was found that relying solely on magnetic force to fix the strap is not very firm. Users only need to pull the strap slightly to cause the magnetic parts to separate from each other; and after long-term use, the magnetic force will gradually weaken, making the watch at risk of sudden falling.

Unless otherwise defined, all technical and scientific terms used in this document have the same meaning as those generally understood by technicians in the technical field of this application. It should also be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. The terms used in this document in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0039] See attached Figure 5 -Attached Figure 11 , a watch buckle structure includes a base 1, a slider 2 and an insert block 3; a card cavity 11 and a slide groove 12 are provided inside the base 1, and the slide groove 12 connects the card cavity 11 with the outside world; the slider 2 can be slidably installed in the slide groove 12, and the head and tail ends of the slider 2 are respectively placed in the outside world and the card cavity 11, and a buckle 22 and a first magnetic component 21 are provided at the tail end of the slider 2; the insert block 3 can be plugged into or out of the card cavity 11, and a locking position 31 and a second magnetic component 32 are provided on the insert block 3; wherein, when the inward moving buckle 22 staggers the locking position 31, the first magnetic component 21 synchronously staggers the second magnetic component 32; when the second magnetic component 32 attracts the first magnetic component 21, the buckle 22 engages the locking position 31.

[0040] Specifically, for ease of understanding, this embodiment is described in conjunction with a conventional watch strap, where two independent watch straps are fixed to the base 1 and the insert 3 respectively.

[0041] When wearing the watch, first press the front end of the slider 2 to move it inward, thereby causing the buckle 22 and the first magnetic part 21 to be misaligned to provide installation conditions for the insert block 3; then release the slider 2, and when the insert block 3 is inserted into the card cavity 11, the second magnetic part 32 can absorb the first magnetic part 21 and drive the slider 2 to move outward until the second magnetic part 32 absorbs the first magnetic part 21 to it, the buckle 22 engages the card position 31, and the front end of the slider 2 is reset, and the insert block 3 can be fixed on the base 1, ensuring that the two watch straps are fixed.

[0042] When removing the watch, first press the front end of the slider 2 to move it inward, so that the buckle 22 and the first magnetic part 21 are separated from the locking position 31 and the second magnetic part 32 respectively, so as to release the restriction on the insert block 3. At this time, the insert block 3 is removed from the card cavity 11 to separate the two watch straps from each other.

[0043] In summary, the present invention designs a card cavity 11 on the base 1 for placing the insert block 3, and designs a slide groove 12 on the base 1 for installing the slider 2, so that the buckle 22 and the first magnetic component 21 on the slider 2 are able to adapt to the clamping position 31 and the second magnetic component 32 on the insert block 3 due to the movable conditions; wherein, when the insert block 3 is installed in the card cavity 11, the coordinated use of the first magnetic component 21 and the second magnetic component 32 can instantly drive the buckle 22 to clamp the clamping position 31, and provide good tactile feedback, thereby improving the operating experience; and after the buckle 22 clamps the clamping position 31, it can increase the firmness between the base 1 and the insert block 3, avoid easily loosening the watch strap, and even if the magnetic force is weakened, the insert block 3 is difficult to detach from the insert block 3, reducing the possibility of the watch falling off suddenly during wearing.

[0044] See attached Figure 7 -Attached Figure 11 A limiting cavity 13 is further provided on the base 1 , and the limiting cavity 13 surrounds and connects to the slide groove 12 ; the head end of the slider 2 is located in the limiting cavity 13 .

[0045] Specifically, when the slider 2 moves inward to a specific position, the head end of the slider 2 abuts against the side wall of the limiting cavity 13 and stops moving; when the slider 2 moves outward to a specific position, the buckle 22 at the tail end of the slider 2 abuts against the side wall of the cavity 11 and stops moving; therefore, the design of the limiting cavity 13 has a limiting function, which can prevent the first magnetic block from being too far away from the second magnetic block and causing the loss of adsorption between the two; at the same time, the limiting cavity 13 can also surround the head end of the slider 2 to improve the overall appearance.

[0046] See attached Figure 7 -Attached Figure 11 The slider 2 is provided with a key groove 23 which is consistent with the length direction of the slide groove 12, and the cavity wall of the limiting cavity 13 is provided with a guide column 130 which slides with the key groove 23.

[0047] Specifically, during the movement of the slider 2, the guide post 130 slides along the key slot 23. When the slider 2 moves outward to a specific position, the guide post 130 abuts the first end of the key slot 23 to limit the slider 2 from continuing to move outward and falling off the base 1. Similarly, when the slider 2 moves outward to a specific position, the guide post 130 abuts the second end of the key slot 23 to limit the slider 2 from continuing to move inward, causing the first magnetic block to completely move away from the second magnetic block.

[0048] Therefore, the coordinated use of the key slot 23 and the guide post 130 can, on the one hand, improve the movement stability of the slider 2 , and on the other hand, limit the range of movement of the slider 2 .

[0049] It should be noted that the manufacturer can adjust the matching position of the guide column 130 and the first and second ends of the key slot 23 to control the range of motion of the slider 2. For example, when the guide column 130 abuts the first end of the key slot 23, the buckle 22 does not contact the side wall of the movable cavity 15, thereby avoiding the buckle 22 from being damaged by a rigid collision with the inner wall of the cavity 11; similarly, when the guide column 130 abuts the second end of the key slot 23, the first end of the slider 2 does not contact the side wall of the limit cavity 13, thereby avoiding the slider 2 from being damaged by a rigid collision with the inner wall of the limit cavity 13.

[0050] See attached Figure 7 -Attached Figure 11 The present invention further includes an elastic member 4 , which is disposed in the limiting cavity 13 , and two ends of the elastic member 4 respectively abut against the head end of the slider 2 and the side wall of the limiting cavity 13 .

[0051] Specifically, when the slider 2 is pressed to move inward, the elastic member 4 is compressed and stores energy; when the insert block 3 is placed in the card cavity 11, the slider 2 is released, the second magnetic member 32 attracts the first magnetic member 21, and at the same time the elastic member 4 releases energy and recovers, so as to synchronously drive the slider 2 to move outward, so that the card block quickly engages the card position 31; when the slider 2 is pressed inward again, the card block disengages from the card position 31, the first magnetic member 21 falls off the second magnetic member 32, and the elastic member 4 is compressed and stores energy again.

[0052] The design of the elastic member 4 enables the slider 2 to have an automatic reset function. Even if the first magnetic member 21 and the second magnetic member 32 lose their magnetic attraction, the base 1 and the insert 3 can still be used normally, thereby extending the overall service life.

[0053] See attached Figure 7 -Attached Figure 11 A support column 25 is provided at the head end of the slider 2, and a socket 131 is provided on the side wall of the limiting cavity 13. One end of the elastic member 4 is placed in the socket 131, and the other end of the elastic member 4 is sleeved on the support column 25; this design can limit the elastic member 4 and prevent the elastic member 4 from shaking at will.

[0054] Furthermore, the elastic member 4 can be of various types, such as a rubber sleeve, a spring, etc. For ease of understanding, the elastic member 4 in this embodiment is a spring.

[0055] See attached Figure 1 -Attached Figure 9A first receiving groove 24 opening upward is provided at the tail end of the slider 2, and the first receiving groove 24 is used to place the first magnetic member 21, and each inner wall of the first receiving groove 24 is provided with a first pressure strip 240 that presses against the first magnetic member 21; a second receiving groove 33 opening downward is provided on the insert block 3, and the second receiving groove 33 is used to place the second magnetic member 32, and each inner wall of the second receiving groove 33 is provided with a second pressure strip 330 that presses against the second magnetic member 32; this design facilitates the installation and disassembly of the first magnetic member 21 and the second magnetic member 32, and facilitates maintenance personnel to replace the first magnetic member 21 or the second magnetic member 32 that has lost its magnetism.

[0056] Among them, the first magnetic attraction component 21 and the second magnetic attraction component 32 can be made of magnets that attract each other; or the first magnetic attraction component 21 can be made of a magnet, and the second magnetic component can be made of a metal material that can be magnetically adsorbed; or the second magnetic attraction component 32 can be made of a magnet, and the first magnetic component can be made of a metal material that can be magnetically adsorbed. There is no restriction on this in the present utility model.

[0057] See attached Figure 5 -Attached Figure 11 The slide groove 12 runs through the two opposite sides of the base 1, and the sliders 2 are provided with two and are slidably installed on the two opposite sides of the base 1; the insert block 3 is provided with two card positions 31 and two second magnetic parts 32, the two card positions 31 correspond one-to-one to the buckles 22 on the two sliders 2, and the two second magnetic parts 32 correspond one-to-one to the first magnetic parts 21 on the two sliders 2.

[0058] Specifically, the design of the two sliders 2 facilitates users to press them synchronously, thereby improving operability; at the same time, it also enables the two buckles 22 and the two first magnetic parts 21 to be evenly connected to the corresponding clamping positions 31 and the second magnetic parts 32, thereby improving structural stability.

[0059] The buckle structure can be adapted to various watch straps, such as the conventional watch strap in the above embodiment, or the more popular single-strand watch strap on the market. This utility model does not limit this; in order to improve the user experience, this utility model takes a single-strand watch strap as an example.

[0060] See attached Figure 1 -Attached Figure 11 A watch strap includes a strap body 5, a first connector 6 and a second connector 7 for connecting to a watch body (not shown), and a buckle structure; the first end of the strap body 5 is fixedly connected to the first connector 6, the second end of the strap body 5 can slide through the second connector 7 and then fold back, the base 1 is set at a specific position of the strap body 5, the insert block 3 is fixedly connected to the second end of the strap body 5, and the insert block 3 is connected to the base 1 to fix the strap body 5.

[0061] Among them, since the base 1 is set at a specific position of the strap body 5, after the insert 3 is connected to the base 1, the length specification of the strap surrounding the wrist is fixed, so this requires the manufacturer to customize it according to the customer's wrist.

[0062] See attached Figure 4 -Attached Figure 9 In order to make the length of the watch strap around the wrist adjustable, in the utility model, a sleeve groove 14 and a locking member 8 are provided on the base 1. The sleeve groove 14 can be slidably mounted on the strap body 5. The locking member 8 is installed in the sleeve groove 14 and can lock or loosen the strap body 5.

[0063] Specifically, the design of the sleeve groove 14 allows the base 1 to slide along the belt body 5, and the design of the lock 8 can lock the belt body 5 so that the base 1 can stop at multiple positions of the belt body 5, thereby meeting the usage needs of different groups of people.

[0064] See attached Figure 4 -Attached Figure 9 The lock member 8 includes a pressure plate 81 and a paddle 82. The base 1 is also provided with an active cavity 15 connected to the sleeve groove 14, and a movable opening 150 is opened on the side wall of the active cavity 15; the pressure plate 81 is located at the connection between the active cavity 15 and the sleeve groove 14, and one end of the pressure plate 81 is provided with a rocker rod 810 extending into the movable opening 150, and the rocker rod 810 can swing at the movable opening 150 so that the pressure plate 81 has a first position of pressing against the belt body 5 and a second position of loosening the belt body 5; the paddle 82 is rotatably installed in the active cavity 15 and is located above the pressure plate 81, and a protrusion 820 is provided on the paddle 82, which can abut or disengage from the pressure plate 81 as the paddle 82 rotates to switch the position of the pressure plate 81.

[0065] Specifically, when it is necessary to adjust the position of the base 1 on the belt body 5, the paddle 82 is rotated to protrude from the movable cavity 15, so that the protrusion 820 disengages from the pressure plate 81, and the rocker arm 810 is loosened to release the restriction of the pressure plate 81 on the belt body 5. In this way, the base 1 can be moved along the belt body 5; after the belt base 1 is moved to a suitable position, the paddle 82 is rotated to make it flat in the movable cavity 15, and the protrusion 820 abuts against the pressure plate 81 to make the rocker arm 810 swing down. At this time, the bottom surface of the belt body 5 is in contact with the bottom wall of the groove 14, and the pressure plate 81 is pressed against the top surface of the belt body 5, so that the base 1 can be locked and fixed on the belt body 5.

[0066] See attached Figure 4 -Attached Figure 9 The lock 8 also includes a support plate 83, the movable cavity 15 is located on the top side of the sleeve groove 14, and the base 1 is also provided with a stepped groove 16 connected to the sleeve groove 14, and the stepped groove 16 is located on the bottom side of the sleeve groove 14. The support plate 83 is located in the sleeve groove 14 and is designed corresponding to the pressure plate 81, and the support plate 83 is provided with a stepped block 830 that slides with the stepped groove 16.

[0067] Specifically, after the pressure plate 81 releases the belt body 5, the support plate 83 can move up and down following the movement of the base 1, thereby playing a certain limiting role and preventing the base 1 from moving too fast; at the same time, the above structural design also facilitates the assembly of the support plate 83.

[0068] It should be noted that a rubber pad 80 can be provided on the side of the pressure plate 81 and the support plate 83 that contacts the belt body 5 to prevent the pressure plate 81 and the support plate 83 from wearing the belt body 5; in addition, the base 1 can be assembled by the base 17 and the top cover 18. Under this design, the assembly of components such as the slider 2 and the elastic member 4 is convenient.

[0069] It should also be noted that although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
