Technical Field

[0001] The utility model relates to the field of watches, in particular to a rigid watch band and a watch strap used for the rigid watch band. Background Art

[0002] Almost all watch straps on the market are flexible straps that can adapt to the changes in hand shape. Common watch straps include rigid straps composed of multiple metal units, leather straps, nylon straps or rubber straps. In addition to personalization considerations, these watch straps usually also consider that the watch straps need to change appropriately according to the shape of the wrist. For a watch strap, the part that needs to change the shape the most is often the back half of the strap, while the strap near the watch dial often only needs a small bend to achieve comfortable wearing of the watch.

[0003] China Utility Model Patent Document Publication No. CN201131372U discloses a metal and leather two-in-one watch strap. This watch strap solves the damage of metal ions in metal watch straps to the human body, avoids allergies, eczema, itching and other symptoms caused by sweating in summer, and the wrist becomes black or green when sweating in summer; while the watch strap makes people feel cold in winter. Cowhide, sheepskin or breathable leather is used, and the inner surface is a strong adhesive. The adhesive is bonded to the inner surface of the metal watch, so that the skin contacts the cowhide, sheepskin or breathable leather, and the original gap of the watch strap is still visible. This watch strap cannot effectively expand the demand for personalized watch straps. Users often only have to choose colors or certain fixed watch strap styles to match their favorite watches.

[0004] In order to solve the above problems, a watch strap is provided, which cleverly utilizes the fact that the rigid strap near the watch dial often only needs a small bend to achieve comfortable wearing of the watch, and makes this part of the strap into an integrally formed rigid strap with certain decorative functions. Users can customize the shape and pattern of the rigid strap according to their preferences, and the other part is a flexible strap, so that it is convenient and comfortable to wear.

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1

[0029] like Figures 1 to 5As shown, the watch rigid band provided in this embodiment includes a retractable shaft 31 and a splicing button 32. The retractable shaft 31 is located at one end of the watch rigid band 1. The number of the retractable shaft 31 is usually one or two. When the number of the retractable shaft 31 is one, it is usually used in conjunction with a fixed shaft. When the number of the retractable shaft 31 is two, the two retractable shafts 31 can be driven to retract simultaneously. Since the splicing button 32 adopts the rigid band 1, a larger splicing button 32 can be designed to facilitate pressing of the finger. The contraction shaft 31 is provided with a passive block 4, and the splicing button 32 is provided with a driving block 5 for driving the passive block 4 to move. The driving block 5 is in contact with the passive block 4. The vertical movement of the splicing button 32 when pressed is converted into the telescopic movement of the telescopic shaft 31 through the relative movement of the driving block 5 and the passive block 4. Therefore, when the splicing button 32 is pressed, the telescopic shaft 31 moves horizontally, and the splicing button 32 and the hole wall of the splicing hole 12 are slidably matched. The hole wall of the splicing hole 12 can limit the movement direction of the splicing button 32, so as to ensure that the splicing button 32 performs a relatively stable vertical movement. The telescopic shaft 31 can be telescoped by pressing the splicing button 32. Compared with the telescopic shaft that can be telescoped by itself in the existing market, the rigid watch band provided in this embodiment makes full use of the easy-to-form characteristics of the rigid band. The pressing area of ​​the splicing button 32 is large, and the pressing is comfortable and convenient. When connected, the telescopic shaft 31 can be telescoped by pressing the splicing button, making the disassembly and assembly of the watch band more convenient.

[0030] In order to restore the retractable shaft 31 to its initial state when the splicing button 32 is not pressed, a return spring 6 is further provided at one end of the retractable shaft 31, and the return spring 6 is connected to one end of the retractable shaft 31. After the splicing button 32 is pressed to retract the retractable shaft 31, the retractable shaft 31 is extended again under the action of the return spring 6 after the splicing button 32 is released, and is thereby inserted into the socket on the dial.

[0031] In order to facilitate the vertical movement of the splicing button 32 when it is pressed to be converted into the telescopic movement of the telescopic shaft 31, further, a passive wedge surface 8 or a pushing arc surface is provided on the passive block 4, and a driving wedge surface 9 or a driving arc surface is provided on the driving block 5. The passive wedge surface 8 is adapted to the driving wedge surface 9 or the pushing arc surface is adapted to the driving arc surface. In actual use, when the driving wedge surface 9 is pushed to move, due to the existence of the driving wedge surface 9, another passive wedge surface 8 adapted thereto will be pushed to move, so that the telescopic shaft 31 is retracted with the retraction of the passive wedge surface 8 under the extrusion of the driving wedge surface 9. When a curved surface is used, a similar principle can also be used. The advantage of the curved surface is that it has less wear during relative motion, but at the same time, the processing cost of the curved surface is relatively high, and it can be reasonably customized according to customer needs in product manufacturing.

[0032] The telescopic shaft 31 includes a main body section 313 and a plug section 314. The diameter of the main body section 313 is larger than the diameter of the plug section 314. The diameter of the plug section 314 is adapted to the plug hole of the dial. The main body section 313 is thicker mainly to ensure stability and reliability during the telescopic process. Of course, the first telescopic shaft 311 and the second telescopic shaft 312 also have a body section 313 and a plug section 314. This embodiment can meet the situation that the telescopic shaft 31 is a single one, and can also meet the situation that the telescopic shaft 31 is a pair.

[0033] The rigid band of the watch also includes a receiving cavity 17 located inside the rigid band of the watch, and the retractable shaft 31 and the splicing button 32 are located in the receiving cavity 17. Most of the retractable shaft 31 and the splicing button 32 are hidden in the receiving cavity 17, and only a small part is exposed. The small part of the head of the retractable shaft 31 is convenient for plugging into the hole on the dial, and the small part of the splicing button 32 is convenient for the user to press by hand. In order to limit the movement of the splicing button 32, the rigid band of the watch also includes a cover plate 3 that is compatible with the shape of the receiving cavity, and the cover plate 3 is provided with an assembly hole 12 that slidably cooperates with the splicing button 32, and the splicing button 32 can slidably cooperate with the hole wall of the assembly hole 12. It can be seen that the hole wall of the assembly hole 12 can limit the movement direction of the splicing button 32, ensuring that the splicing button 32 performs relatively stable vertical movement.

[0034] Embodiment 2

[0035] like Figure 6 As shown, the rigid watch band provided in this embodiment includes a retractable shaft 31 and a splicing button 32. The retractable shaft 31 is located at one end of the rigid watch band 1. A passive block 4 is arranged on the retractable shaft 31. A driving block 5 for driving the passive block 4 to move is arranged on the splicing button 32. The driving block 5 is in contact with the passive block 4. When the splicing button 32 is pressed, the retractable shaft 31 moves horizontally.

[0036] The difference between the second embodiment and the first embodiment is that:

[0037] The telescopic shaft 31 includes a first telescopic shaft 311 and a second telescopic shaft 312, the first telescopic shaft 311 and the second telescopic shaft 312 are symmetrically arranged, the passive block 4 includes a first passive block 41 and a second passive block 42, the passive wedge surfaces 8 on the first passive block 41 and the second passive block 42 are symmetrically distributed, the first passive block 41 is fixed on the first telescopic shaft 311, and the second passive block 42 is fixed on the second telescopic shaft 312, the driving block 5 includes a first driving block 51 and a second driving block 52, and the driving wedge surface 8 on the first driving block 51 is symmetrically distributed. The first driving block 51 is located on the inner side of one end of the splicing button 32, and the second driving block 52 is located on the inner side of the other end of the splicing button 32. The first driving block 51 contacts the first passive block 41, and the second driving block 52 contacts the second passive block 42. The two passive wedge surfaces 8 are located between the two driving wedge surfaces 9. In this way, when the splicing button 32 moves vertically, it can simultaneously drive the first telescopic shaft 311 and the second telescopic shaft 312 to perform telescopic movement. Further preferably, one end of the return spring 6 is connected to the first telescopic shaft 311, and the other end of the return spring 6 is connected to the second telescopic shaft 312. Since the first telescopic shaft 311 and the second telescopic shaft 312 need rebound forces in opposite directions when rebounding, a return spring 6 can be shared. This arrangement not only makes full use of the rebound force of the return spring 6, but also reduces the cost. A limit table 7 is provided in the middle of the first drive block 51 and the second drive block 52. The limit table 7 can limit the displacement range of the splicing button 32, because the limit table 7 contacts the inner wall of the slot body of the rigid belt 1, which makes the splicing button 32 unable to move, thereby well controlling the telescopic distance of the two telescopic shafts and preventing excessive compression of the spring, thereby improving the service life of the spring. In summary, when a symmetrical design is adopted and the return spring 6 is shared, the telescopic shaft can be telescoped at both ends, making the disassembly and assembly alignment simple. In the prior art, one end of the shaft is often inserted first, and the other end is telescoped and aligned before being inserted. However, the method provided by the present application only requires pressing a button to achieve telescopic movement at both ends of the telescopic shaft, and alignment is convenient.

[0038] Embodiment 3

[0039] A watch strap provided in this embodiment includes the above-mentioned rigid watch strap and flexible strap 2, the retractable shaft 31 is located at one end of the rigid strap 1, and the flexible strap 2 is detachably connected to the other end of the rigid watch strap.

[0040] The watch rigid band provided in this embodiment also includes a flexible band 2, one end of which is detachably connected to the rigid band 1 via a detachable joint 10. The rigid band 1 is integrally formed and will not deform, and can usually be set as a plastic band or a metal band, such as an integrally formed stainless steel band, a titanium band, a hard plastic band, etc. The flexible band 2 can be a traditional metal watch rigid band, a leather watch rigid band, a rubber watch rigid band, a nylon watch rigid band, etc.

[0041] A slot 11 is provided on the flexible belt 2, and the detachable joint 10 includes a hook 101 and a disassembly button 102 that are compatible with the slot 11. At least one disassembly spring 103 is provided on the inner side of the disassembly button 102, and usually two disassembly springs 103 are provided to ensure that both ends of the disassembly button 102 are evenly stressed. One end of the hook 101 is connected to the disassembly button 102, and the hook 101 moves horizontally when the splicing button 32 is pressed. Under the elastic force of the disassembly spring 103, when the hook 101 is inserted into the slot 11, it can no longer escape from the slot 11. Only when the disassembly spring 103 is pressed, the disassembly spring 103 shortens the splicing button 32 to drive the hook 101 to escape from the slot 11. In actual use, the assembly of the flexible belt 2 can be completed by pressing the disassembly spring 103, which is very simple and quick. Further preferably, a disassembly hole 11 is provided on the inner side surface of the rigid belt 1 , and the disassembly button 102 is slidably matched with the hole wall of the disassembly hole 11 , so that the disassembly button 102 maintains the stability of movement through the disassembly hole 11 .

[0042] In addition, the rigid watch strap provided in this embodiment is also provided with a fixed ring 13 and a movable ring 14. The fixed ring 13 is located at the end of the flexible band 2, and the movable ring 14 is sleeved on the flexible band 2. By adjusting the relative positions of the fixed ring 13 and the movable ring 14, the excess watch strap can be better fixed.

[0043] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the claims of this application are within the scope of protection of the present invention.
