Technical Field

[0001] This invention relates to a watch strap, and more particularly to a deformable watch strap with a nickel-titanium memory alloy spring, belonging to the technical field of watch straps. Background Technology

[0002] A deformable watch strap with a nickel-titanium memory alloy spring is a type of watch strap made with a nickel-titanium memory alloy spring. Because nickel-titanium alloy has memory elasticity, the strap can be bent and deformed at will in 360°, and it can return to its original shape instantly when released.

[0003] Existing deformable watch straps with nickel-titanium shape memory alloy springs require bolts for installation during actual use. This necessitates the use of tools for installation, and if these tools are damaged, the strap cannot be installed, making installation inconvenient. Summary of the Invention

[0004] The main objective of this invention is to solve the problem of inconvenient watch strap installation by providing a deformable watch strap with a nickel-titanium shape memory alloy spring.

[0005] The objective of this invention can be achieved by adopting the following technical solution: A deformable watch strap with a nickel-titanium shape memory alloy spring includes a watch case assembly and a strap assembly mounted on the watch case assembly. The strap assembly is equipped with an mounting assembly, the watch case assembly is equipped with a protective assembly, the watch case assembly is equipped with a guide assembly, the guide assembly is equipped with a limiting assembly, the protective assembly is equipped with a positioning assembly, the positioning assembly is equipped with a locking assembly, and the protective assembly is equipped with a pulling assembly.

[0006] Preferably, the watch case assembly includes a watch case and a slot, wherein the watch case has a slot.

[0007] Preferably, the watch strap assembly includes a nickel-titanium memory alloy spring watch strap and a connecting block, the connecting block is provided on the watch case, and the nickel-titanium memory alloy spring watch strap is installed on the connecting block.

[0008] Preferably, the mounting component includes a mounting block and a mounting groove, the mounting block is mounted on the connecting block, and the casing has a mounting groove that cooperates with the mounting block.

[0009] Preferably, the protective component includes a protective plate, a slider, and a groove. The protective plate is installed on the watch case, the slider is installed on the watch case, and the protective plate has a groove that cooperates with the slider. The slider is a T-shaped slider, and the groove is a T-shaped groove.

[0010] Preferably, the pulling assembly includes a pull bar and an anti-slip strip, the protective plate has a pull cavity, the pull bar is installed inside the pull cavity, and the anti-slip strip is installed on the pull bar.

[0011] Preferably, the guiding assembly includes a guide rod, a guide ring, a connecting rod, and a first return spring. The guide rod is mounted on the watch case, the guide ring is slidably mounted on the guide rod, the guide ring is connected to the watch case via the first return spring, and the connecting rod is mounted on the guide ring.

[0012] Preferably, the limiting component includes a pull plate, a pull rod, a limiting block, and an insert block. The pull plate is installed on the connecting rod, the pull rod is installed on the pull plate, the limiting block is installed on the connecting rod, and the insert block is installed on the limiting block. The watch case and the mounting block are both provided with limiting grooves that cooperate with the insert block.

[0013] Preferably, the positioning component includes a positioning block and a positioning groove. The positioning block is installed on the protective plate, the engaging component is installed on the positioning block, and the positioning groove that cooperates with the positioning block is provided on the limiting block.

The positioning block has a cavity, the second return spring is installed inside the cavity, a locking ball is installed at one end of the second return spring, and the limiting block has a locking groove that cooperates with the locking ball.

[0015] Beneficial technical effects of the present invention: The deformable watch strap with a nickel-titanium memory alloy spring according to the present invention features a guide rod slidably connected to a guide ring. Pulling a pull plate causes the guide ring to slide on the guide rod. As the guide ring slides on the guide rod, it moves a limiting block. When the limiting block moves, it moves an insert block, which slides out of the limiting groove. Pulling the mounting block then slides it out of the mounting groove. This design facilitates the removal and replacement of damaged nickel-titanium memory alloy spring watch straps without requiring tools. Disassembly is convenient and less prone to failure due to tool damage, thus simplifying the process.

[0016] By setting a protective plate, the mounting block is inserted into the mounting groove. Releasing the pull plate causes the first return spring to extend, which in turn drives the guide ring to slide on the guide rod. When the guide ring slides on the guide rod, it moves the limiting block. When the limiting block moves, it moves the insert block, which is then inserted into the limiting groove. This facilitates the installation of the nickel-titanium memory alloy spring watchband. After installation, the protective plate is installed on the watch case, and the slider slides into the groove, protecting the first return spring and making it waterproof. This prevents the first return spring from being damaged by water corrosion, thus extending the watchband's lifespan. By setting a positioning block and inserting it into the positioning groove, the sliding limiting block is positioned, thus facilitating the positioning of the installed nickel-titanium memory alloy spring watchband.

[0019] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0020] like Figures 1-10 As shown, the deformable watch strap with a nickel-titanium memory alloy spring provided in this embodiment includes a watch case assembly and a strap assembly mounted on the watch case assembly. The strap assembly is equipped with an mounting component, the watch case assembly is equipped with a protective component, the watch case assembly is equipped with a guide component, the guide component is equipped with a limit component, the protective component is equipped with a positioning component, the positioning component is equipped with a locking component, and the protective component is equipped with a pulling component. The watch case assembly includes a watch case 1 and a slot 11, with the slot 11 formed on the watch case 1. The strap assembly includes a nickel-titanium memory alloy spring strap 2 and a connecting block 21, with the connecting block 21 provided on the watch case 1. The watch case 1 is equipped with a nickel-titanium memory alloy spring strap 2. The mounting components include a mounting block 3 and a mounting groove 31. The mounting block 3 is mounted on the connecting block 21. The watch case 1 has a mounting groove 31 that mates with the mounting block 3. The guide assembly includes a guide rod 6, a guide ring 61, a connecting rod 62, and a first return spring 63. The guide rod 6 is mounted on the watch case 1, and the guide ring 61 is slidably mounted on the guide rod 6. The guide ring 61 is connected to the watch case 1 through the first return spring 63. The connecting rod 62 is mounted on the guide ring 61. The limiting assembly includes a pull plate 7, a pull rod 71, a limiting block 72, and an insert block 73. The pull plate 7 is mounted on the connecting rod 62. A pull rod 71 is installed, a limit block 72 is installed on the connecting rod 62, and an insert block 73 is installed on the limit block 72. Both the case 1 and the mounting block 3 have limit grooves that cooperate with the insert block 73. A guide rod 6 is slidably connected to a guide ring 61. Pulling the pull plate 7 causes the guide ring 61 to slide on the guide rod 6. When the guide ring 61 slides on the guide rod 6, it causes the limit block 72 to move. When the limit block 72 moves, it causes the insert block 73 to move, sliding it out of the limit groove. Pulling the mounting block 3 causes it to slide out of the mounting groove, facilitating the disassembly and replacement of damaged nickel-titanium watches. The nickel-titanium memory alloy spring watch strap 2 can be disassembled without the need for staff to carry tools, making disassembly relatively convenient and less likely to be impossible due to tool damage. The installation block 3 and installation groove 31 cooperate to facilitate the installation of the nickel-titanium memory alloy spring watch strap 2. The guide rod 6 and guide ring 61 cooperate to guide and limit the insertion block 73. The first reset spring 63 facilitates the reset of the limit block 72. The pull rod 71 and pull plate 7 cooperate to guide and limit the insertion block 73.

[0021] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the protective assembly includes a protective plate 4, a slider 41, and a groove 42. The protective plate 4 and slider 41 are mounted on the watch case 1. The protective plate 4 has a groove 42 that cooperates with the slider 41. The slider 41 is a T-shaped slider, and the groove 42 is a T-shaped groove. The pulling assembly includes a pull bar 5 and an anti-slip strip 51. The protective plate 4 has a pull cavity, inside which the pull bar 5 is installed. The anti-slip strip 51 is installed on the pull bar 5. The positioning assembly includes a positioning block 8 and a positioning groove 81. The positioning block 8 is mounted on the protective plate 4, and a locking assembly is installed on the positioning block 8. The limiting block 72 has a locking mechanism that cooperates with the positioning... The positioning slots 81 of the positioning blocks 8 cooperate with each other. The engaging assembly includes a retaining ball 9, a second return spring 91, and a cavity 92. The positioning block 8 has a cavity 92, and the second return spring 91 is installed inside the cavity 92. The retaining ball 9 is installed at one end of the second return spring 91. The limiting block 72 has a slot that cooperates with the retaining ball 9. By setting the protective plate 4, the mounting block 3 is inserted into the mounting slot. When the pull plate 7 is released, the first return spring 63 extends, thereby driving the guide ring 61 to slide on the guide rod 6. When the guide ring 61 slides on the guide rod 6, it can drive the limiting block 72 to move. When 72 moves, it can drive the insert 73 to move, inserting the insert 73 into the limiting groove, which facilitates the installation of the nickel-titanium memory alloy spring watch strap 2. After installation, the protective plate 4 is installed on the watch case 1, and the slider 41 slides into the slide groove 42, which facilitates the protection of the first return spring 63 and waterproofs the first return spring 63. This prevents the first return spring 63 from being damaged by water corrosion, thereby improving the service life of the watch strap. By setting the positioning block 8, the positioning block 8 is inserted into the positioning groove 81, which facilitates the limiting of the sliding. The positioning block 72 provides a limit, which facilitates the positioning of the installed nickel-titanium memory alloy spring watch strap 2. The slider 41 is slidably connected to the slide groove 42, which facilitates the installation of the protective plate 4. The retaining ball 9 is engaged with the retaining groove, which allows the protective plate 4 to be installed on the watch case 1. The slider 41 slides into the slide groove 42, and the positioning block 8 is inserted into the positioning groove 81. When the positioning block 8 slides in the positioning groove 81, when the retaining ball 9 is aligned with the retaining groove, the second return spring 91 extends, thereby driving the retaining ball 9 to move and engage the retaining ball 9 into the retaining groove, which facilitates the positioning of the installed protective plate 4.

[0022] In this embodiment, as Figures 1-10 As shown in the figure, the working process of the deformable watch strap with a nickel-titanium shape memory alloy spring provided in this embodiment is as follows: Step 1: Pull the protective plate 4 to slide the positioning block 8 out of the positioning groove 81 and the locking ball 9 out of the groove to disassemble the protective plate 4. Move the pull plate 7. When the pull plate 7 moves, it drives the guide ring 61 to slide on the guide rod 6. When the guide ring 61 slides on the guide rod 6, it drives the limit block 72 to move. When the limit block 72 moves, it drives the insertion block 73 to move and slide the insertion block 73 out of the limit groove. Step 2: Insert the mounting block 3 into the mounting groove, release the pull plate 7, the first reset spring 63 extends, and then drives the guide ring 61 to slide on the guide rod 6. When the guide ring 61 slides on the guide rod 6, it drives the limit block 72 to move. When the limit block 72 moves, it drives the insert block 73 to move and insert the insert block 73 into the limit groove to install the nickel-titanium memory alloy spring watch strap 2. Step 3: After installation, install the protective plate 4 on the watch case 1, slide the slider 41 into the slide groove 42, insert the positioning block 8 into the positioning groove 81, and when the positioning block 8 slides in the positioning groove 81, when the locking ball 9 is aligned with the groove, the second reset spring 91 extends, thereby driving the locking ball 9 to move and lock the locking ball 9 into the groove, thus limiting the installation of the protective plate 4.

[0023] In summary, in this embodiment, the deformable watch strap with a nickel-titanium memory alloy spring, through the sliding connection between the guide rod 6 and the guide ring 61, allows the guide ring 61 to slide on the guide rod 6 when the pull plate 7 is pulled. When the guide ring 61 slides on the guide rod 6, it moves the limiting block 72. When the limiting block 72 moves, it moves the insert block 73, causing it to slide out of the limiting groove. Pulling the mounting block 3 then allows it to slide out of the mounting groove. This facilitates the disassembly and replacement of the damaged nickel-titanium memory alloy spring watch strap 2, eliminating the need for workers to carry tools to disassemble the watch strap 2. The disassembly is relatively simple. The design is convenient and unlikely to result in the inability to disassemble the nickel-titanium memory alloy spring watch strap 2 due to tool damage, thus facilitating disassembly. The installation block 3 and installation slot 31 work together to facilitate the installation of the nickel-titanium memory alloy spring watch strap 2. The guide rod 6 and guide ring 61 work together to guide and limit the insertion block 73. The first reset spring 63 facilitates the reset of the limiting block 72. The pull rod 71 and pull plate 7 work together to guide and limit the insertion block 73. With the protective plate 4, the installation block 3 is inserted into the installation slot. Releasing the pull plate 7 extends the first reset spring 63, thereby driving the guide ring 61. Sliding on the guide rod 6, when the guide ring 61 slides on the guide rod 6, it can drive the limiting block 72 to move. When the limiting block 72 moves, it can drive the insert block 73 to move, inserting the insert block 73 into the limiting groove, which facilitates the installation of the nickel-titanium memory alloy spring watch strap 2. After installation, the protective plate 4 is installed on the watch case 1, and the slider 41 slides into the slide groove 42, which facilitates the protection of the first return spring 63 and waterproofs the first return spring 63. This prevents the first return spring 63 from being damaged by water corrosion, thereby improving the service life of the watch strap. By setting the positioning block 8, the positioning block 8 is positioned... Inserting into the positioning groove 81 facilitates the limiting of the sliding limit block 72, thereby facilitating the limiting of the installed nickel-titanium memory alloy spring watch strap 2. By setting the slider 41 to slide in the groove 42, it is easy to install the protective plate 4. By setting the locking ball 9 to engage with the slot, the protective plate 4 is installed on the watch case 1. The slider 41 slides into the groove 42, and the positioning block 8 is inserted into the positioning groove 81. When the positioning block 8 slides in the positioning groove 81, when the locking ball 9 is aligned with the slot, the second return spring 91 extends, thereby driving the locking ball 9 to move and lock the locking ball 9 into the slot, which facilitates the limiting of the installed protective plate 4.
