[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 Figure 1 , Figure 3 , Figure 4 , Figure 7 as well as Figure 8 As shown, the easy-to-assemble watch strap provided in this embodiment is an easy-to-assemble watch strap, comprising a rigid band 1 and a flexible band 2, one end of the flexible band 2 is detachably connected to one end of the rigid band 1 through a detachable joint 10, and the rigid band 1 is integrally formed and will not deform, and can usually be set as a plastic band or a metal band, for example: an integrally formed stainless steel band, a titanium band, a hard plastic band, etc. The flexible band 2 can be a traditional metal easy-to-assemble watch strap, a leather easy-to-assemble watch strap, a rubber easy-to-assemble watch strap, a nylon easy-to-assemble watch strap, etc. A snap ring 11 is provided on the flexible band 2, and the detachable joint 10 includes a hook 101 and a disassembly button 102 adapted to the snap ring 11, and at least one disassembly spring 103 is provided on the inner side of the disassembly button 102, and one end of the hook 101 is connected to the disassembly button 102, and the hook 101 moves horizontally when the disassembly button 102 is pressed. Specifically, 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 the two ends of the disassembly button 102 are evenly stressed. One end of the hook 101 is connected to the disassembly button 102. When the disassembly button 102 is pressed, the hook 101 moves horizontally. Under the elastic force of the disassembly spring 103, when the hook 101 is stuck in the snap ring 11, it can no longer escape from the snap ring 11. Only when the disassembly spring 103 is pressed again, the disassembly spring 103 shortens the disassembly button 102 to drive the hook 101 to escape from the snap ring 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. This structure can drive the hook 101 to move horizontally when pressing the disassembly button 102, so that the rigid belt 1 and the flexible belt 2 can be quickly disassembled and assembled by pressing one button, which is convenient to use. Further preferably, a disassembly hole 17 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 17 , and the stability of the movement of the disassembly button 102 is maintained by the limiting effect of the disassembly hole 17 .

[0030] In order to maintain the simple and beautiful appearance of the rigid belt 1, it is further preferred that an assembly cavity 16 is provided on the inner side of the rigid belt 1, and the detachable joint 10 is located in the assembly cavity 16, so that the detachable joint 10 is hidden in the rigid belt 1. During actual use, the snap ring 11 on the flexible belt 2 is extended into the assembly cavity 16 and snap-fitted with the hook head 011, so as to realize the connection between the rigid belt 1 and the flexible belt 2. The rigid belt 1 has a simple and beautiful appearance.

[0031] Since the pressing position and the snap-on position are not in the same plane, further, the hook 101 includes a hook head 011, a connecting plate 012 and a fixing plate 013. The hook head 011 is connected to the fixing plate 013 through the connecting plate 012. The fixing plate 013 is fixed to the inner middle part of the disassembly button 102. The connecting plate 012 is usually perpendicular to the plane where the hook head 011 and the fixing plate 013 are located, so as to adapt to the situation where the pressing position and the snap-on position are not in the same plane. This arrangement makes the disassembly button 102 located on the inner surface of the rigid belt 1, and the hook 101 is located in the middle or upper middle part of the rigid belt 1 in the thickness direction, so as to facilitate pressing the disassembly button 102, and also help to maintain the aesthetics of the installation position of the disassembly button 102. Further preferably, a scissor mouth 014 is provided in the middle of one end of the fixing plate 013, and a limit rivet 15 is provided in the scissor mouth 014, and the limit rivet 15 is connected to the disassembly button 102. In actual production, the disassembly button 102 and the limit rivet 15 can be integrally formed, or the limit rivet 15 is first fixed to the disassembly button 102. In this way, when installing the fixing plate 013, the fixing plate 013 can be directly inserted into the gap between the limit rivet 15 and the disassembly button 102 from the scissor mouth 014 in the middle of one end of the fixing plate 013 through interference fit. This installation method not only saves materials but also is faster to install, and can effectively improve the production efficiency of the product.

[0032] The hook 101 is strip-shaped, so that the larger clamping surface makes the clamping more stable. Correspondingly, the clamping ring 11 includes a cross bar 111 and two side bars 112. The two ends of the cross bar 111 are respectively connected to the two side bars 112. The cross bar 111 and the two side bars 112 form a hollow rectangular frame. The hole in the middle of the hollow rectangular frame is just adapted to the hook 101, so that the hook 101 can be stably clamped in the hole of the hollow rectangular frame.

[0033] In addition, in order to improve production efficiency, the clamping ring 11 and the flexible belt 2 can be integrally formed by a mold, especially for the flexible belt 2 made of rubber. If other materials are not suitable for integral molding, the flexible belt 2 can be provided with a connector, and the clamping ring 11 can also be integrally formed with the connector. Preferably, the hook 101 is configured as a metal hook, which is not prone to wear and tear, and can effectively increase the service life of the hook 101.

[0034] like Figures 1 to 5 As shown, the other end of the rigid belt 1 is provided with an assembling head 3, and the assembling head 3 includes a retractable shaft 31 and a splicing button 32. 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 belt 1, a larger splicing button 32 can be designed and set, so that it is convenient for fingers to press it. The retractable shaft 31 is provided with a There is a passive block 4, and a driving block 5 for driving the passive block 4 to move is arranged on the splicing button 32. The driving block 5 contacts the passive block 4. The relative movement of the driving block 5 and the passive block 4 makes the vertical movement of the splicing button 32 when pressed be converted into the telescopic movement of the telescopic shaft 31. Therefore, when the splicing button 32 is pressed, the telescopic shaft 31 moves horizontally, and the splicing button 32 slides with the hole wall of the splicing hole 12. 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 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 easy-to-assemble watchband provided in this embodiment makes full use of the easy-to-form characteristics of the rigid belt. 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 watchband more convenient.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] Embodiment 2

[0039] like Figure 6 As shown, the easy-to-assemble watch strap provided in this embodiment includes a rigid band 1 and a flexible band 2 which are arc-shaped and integrally formed. One end of the rigid band 1 is connected to the flexible band 2. An assembling head 3 is provided at one end of the rigid band 1. The assembling head 3 includes a retractable shaft 31 and a splicing button 32. A passive block 4 is provided on the retractable shaft 31. A driving block 5 for driving the passive block 4 to move is provided 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.

[0040] The difference between the second embodiment and the first embodiment is that:

[0041] The telescopic shaft 31 includes a first telescopic shaft 311 and a second telescopic shaft 312, and 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. The driving wedge surface 9 on the first driving block 51 and the driving wedge surface 9 on the second driving block 52 are relatively arranged. 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 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.

[0042] 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.
