Description

Technical Field

[0001] This utility model relates to the field of watch cases, and more specifically, to a replaceable watch case structure. Background Technology

[0002] The watch case is a crucial component of a watch, acting as its "outer shell." Its primary function is to protect the internal components such as the movement, dial, and hands. It's also a key element in the watch's design, directly influencing its style and overall feel. Watch cases are typically made of materials like metal, ceramic, plastic, and leather. Their structure includes an inner bezel housing the movement, lugs connecting the watch to the strap, a crystal mount to protect the dial, and a case back. Not only does it protect the internal components from impacts, dust, and moisture, but its design, materials, and craftsmanship also showcase the watch's personality and sophistication.

[0003] The existing technologies on the market still have the following shortcomings:

[0004] (1) Most existing watch cases are designed as a single unit, with each part of the case fixedly connected. This makes it difficult to meet users’ diverse needs for personalized appearance. Furthermore, the parts are prone to loosening during use after being connected, affecting the overall stability of the watch case structure.

[0005] (2) Moreover, the installation adaptability is weak and the protection is insufficient, and the maintenance is inconvenient. The internal installation structure of the existing watch case is simple and cannot be adapted to watch movements of different specifications. The versatility is poor and the overall structural stability is insufficient. These design defects make the assembly and maintenance process of the existing watch case cumbersome and the reliability of use low.

[0006] This leads to the proposal of a replaceable watch case structure. Utility Model Content

[0007] The purpose of this utility model is to address the existing problems.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] The present invention is as follows: a replaceable watch case structure, comprising a main body, a supporting shell being snapped onto the inner surface of the main body, a limiting baffle being fixedly connected to the front surface of the supporting shell, and a protective frame being fixedly connected to the side surface of the main body.

[0010] A fixing block is fixedly connected to one side of the main body of the object, a nut is fixedly connected to one side of the fixing block, and an inner protective frame is fixedly connected to the front surface of the supporting shell.

[0011] A sleeve ring is fixedly connected to the inner surface of the object body, and a plug-in bottom shell is limited and snapped onto the inner surface of the object body.

[0012] As a preferred technical solution of this utility model, an outer frame is fixedly connected to the front surface of the plug-in bottom shell, and the outer frame is connected to the main body of the object through the plug-in bottom shell. The outer frame not only enriches the appearance of the watch case, but also allows for quick assembly and disassembly through the connection between the plug-in bottom shell and the main body of the object. When the user wants to change the style of the watch, they only need to remove the plug-in bottom shell to replace the outer frame together, which is simple and convenient. At the same time, the outer frame also protects the connection between the plug-in bottom shell and the main body of the object, reducing wear and tear during daily use.

[0013] As a preferred technical solution of this utility model, a mounting plate is fixedly connected to one side of the sleeve ring, and the mounting plate is arranged around the main body of the object, providing a stable mounting base for internal components such as the watch movement. The surrounding structure ensures that the movement is subjected to uniform force, avoiding watch malfunctions due to unstable installation. It also accommodates the installation needs of movements of different sizes, enhancing the versatility and compatibility of the watch case structure, and making the assembly process more flexible and efficient.

[0014] As a preferred technical solution of this utility model, the front surface of the mounting plate has multiple mounting openings. These openings can be flexibly selected according to the fixing hole positions of the movement, facilitating the secure fixing of the movement to the mounting plate using screws or other connecting components. This multi-opening design not only improves installation accuracy but also adapts to the installation requirements of different movement models, further enhancing the compatibility of the watch case structure. It also facilitates later disassembly and repair of the movement.

[0015] As a preferred technical solution of this utility model, the inner ring surface of the nut is limited by a threaded rod, and the threaded rod is connected between the nut and the fixing block. The limited connection between the threaded rod and the nut can strengthen the connection between the object body and the support shell. After the support shell is installed by the limited locking, rotating the threaded rod to tighten it against the support shell can effectively prevent the support shell from loosening or shifting during use, ensuring the stability of the case structure. At the same time, the detachable design of the threaded rod does not affect the later replacement of the support shell.

[0016] As a preferred technical solution of this utility model, the nut is connected to the object body through a fixing block, and the fixing blocks are symmetrically arranged vertically with the horizontal bisector of the nut as the axis of symmetry. The symmetrical fixing blocks can stably fix the nut to the object body, so that the nut will not shift during the tightening or loosening of the threaded rod. This symmetrical structural design disperses the force applied by the threaded rod, reduces local wear on the object body, extends the service life of the case, and ensures the stability and reliability of the reinforcement operation.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The main body of the watch features a locking design where the inner surface of the main body, the supporting shell, and the insert base shell are all connected by a locking mechanism. The outer frame connects to the main body via the insert base shell, facilitating quick disassembly and replacement of different styles of supporting shells, insert base shells, and outer frames. This allows for easy transformation of the watch case style, satisfying diverse user needs for personalized watch appearances. Simultaneously, the fixing blocks are symmetrically arranged above and below the horizontal nut dividing line, with the threaded rod and nut providing a locking connection. This reinforces the connection between the main body and each component, preventing loosening after replacement and ensuring the stability of the watch case structure.

[0019] 2. A mounting plate, centered on the main body of the watch, is connected to the inner ring of the main body via a connecting ring. Multiple mounting openings facilitate the secure installation of internal components such as the watch movement into the watch case using connectors, adapting to different movement sizes and enhancing the watch case's versatility. The inner ring protective frame and the protective frame respectively protect the inner ring and sides of the watch case, reducing component wear; the limiting baffle restricts the displacement of the supporting case, further improving the overall structural stability. The overall design balances ease of installation with reliable use, making watch case assembly and maintenance more convenient. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0026] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Please see Figure 1-4 The present invention provides a technical solution: a replaceable watch case structure, including a main body 1, a supporting shell 13 that is limited and snapped onto the inner surface of the main body 1, a limiting baffle 2 that is fixedly connected to the front surface of the supporting shell 13, and a protective frame 9 that is fixedly connected to the side surface of the main body 1.

[0030] In this embodiment, an outer frame 4 is fixedly connected to the front surface of the insert-back case 3, and the outer frame 4 connects the insert-back case 3 and the main body 1. The outer frame 4 not only enriches the appearance of the watch case, but also allows for quick assembly and disassembly through the connection between the insert-back case 3 and the main body 1. When the user wants to change the style of the watch, they only need to remove the insert-back case 3, and the outer frame 4 can be replaced along with it. The operation is simple and convenient. At the same time, the outer frame 4 also protects the connection between the insert-back case 3 and the main body 1, reducing wear and tear during daily use. A mounting plate 7 is fixedly connected to one side of the sleeve ring 5, and the mounting plate 7 is arranged around the main body 1 as the center point. The mounting plate 7 provides a stable mounting base for internal components such as the watch movement. The surrounding structure can make the movement evenly stressed, avoiding watch malfunctions due to unstable installation. At the same time, it adapts to the installation requirements of movements of different sizes, enhancing the versatility and compatibility of the watch case structure, making the assembly process more flexible and efficient.

[0031] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a fixing block 10 is fixedly connected to one side of the object body 1, a nut 11 is fixedly connected to one side of the fixing block 10, and an inner protective frame 6 is fixedly connected to the front surface of the support shell 13.

[0032] In this embodiment, the front surface of the mounting plate 7 has multiple mounting openings 8. These openings can be flexibly selected according to the fixing holes of the movement, facilitating the secure fixing of the movement to the mounting plate 7 using screws or other connectors. This multi-opening design not only improves installation accuracy but also adapts to the installation requirements of different movement models, further enhancing the adaptability of the watch case structure. It also facilitates later disassembly and repair of the movement. A threaded rod 12 is connected to the inner ring surface of the nut 11, and the threaded rod 12 is connected to the fixing block 10 via the nut 11. This connection between the threaded rod 12 and the nut 11 reinforces the connection between the main body 1 and the support shell 13. After the support shell 13 is installed via the limiting snap-fit, rotating the threaded rod 12 tightens it against the support shell 13, effectively preventing loosening or displacement of the support shell 13 during use, ensuring the stability of the watch case structure. Furthermore, the detachable design of the threaded rod 12 does not affect the later replacement of the support shell 13.

[0033] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a sleeve ring 5 is fixedly connected to the inner ring surface of the object body 1, and a plug-in bottom shell 3 is limited and snapped onto the inner ring surface of the object body 1.

[0034] In this embodiment, the nut 11 is connected to the object body 1 via the fixing block 10. The fixing block 10 is symmetrically arranged vertically about the horizontal bisector of the nut 11. The symmetrical fixing blocks 10 can stably fix the nut 11 to the object body 1, so that the nut 11 will not shift during the tightening or loosening of the threaded rod 12. This symmetrical structural design disperses the force applied by the threaded rod 12, reduces local wear on the object body 1, extends the service life of the case, and ensures the stability and reliability of the reinforcement operation.

[0035] Specifically, in use, this replaceable watch case structure works as follows: The support shell 13 is secured to the inner ring surface of the main body 1. The limiting baffle 2 on the front surface of the support shell 13 fits snugly against the inner ring of the main body 1, restricting the displacement of the support shell 13. The insert base shell 3 is then inserted into the inner ring of the main body 1, forming a fit with the support shell 13. The outer frame 4 on the front surface of the insert base shell 3 is thus fixed, together with the main body 1, forming the basic frame of the watch case. On one side of the inner ring of the main body 1, a mounting plate 7, centered on the main body 1, secures the watch movement with screws through multiple mounting openings 8. An inner ring protective frame 6 surrounds the outside of the movement, protecting it from wear. Fixing blocks 10 on one side of the main body 1 are symmetrically arranged above and below the horizontal axis of the nut 11, firmly securing the nut 11. Rotating the threaded rod 12 connects it to the fixing block 10 via the nut 11, tightening the support shell 13 and reinforcing the connection between the support shell 13 and the main body 1, preventing loosening. The protective frame 9 on the side of the main body 1 wraps around the edge of the watch case to prevent damage from bumps and knocks during daily use. If the watch case style needs to be changed, first reverse the threaded rod 12 to detach it from the support shell 13, then remove the support shell 13. Pull out the insert back shell 3, removing it along with the outer frame 4. Replace it with a new support shell 13 and insert back shell 3, and insert them into the main body 1 following the same steps. Then secure them with the threaded rod 12 and nut 11 to complete the quick replacement of the watch case appearance. Regularly check the connection status of each component, and check the movement's fixation on the mounting plate 7 through the installation opening 8 to ensure the movement is secure. Check if the connection between the threaded rod 12 and nut 11 is loose, and whether the fixing block 10 is intact. Clean the dust from the inner bezel protective frame 6 and protective frame 9 to ensure the stability and lifespan of the overall watch case structure.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
