Description
Technical Field
[0001] The utility model relates to the technical field of mechanical watches, in particular to a fine-tuning mechanism for the running accuracy of a mechanical watch. Background Technique
[0002] As a precision timing tool, the running accuracy of a mechanical watch directly affects the user's grasp of time and the use experience. In modern society, although electronic devices have been widely popularized, mechanical watches are still favored by many consumers for their exquisite craftsmanship, unique mechanical beauty, and traditional value. Especially for some people with high requirements for time accuracy, such as business people, athletes, collectors, etc., the running accuracy of mechanical watches is crucial.
[0003] In the prior art, when an existing fine-tuning mechanism for the running accuracy of a mechanical watch is used for a long time, it will cause wear to the fine-tuning rotating block for fine-tuning outside the main body of the mechanical watch. Moreover, the traditional fine-tuning rotating block is integrated with the main body of the mechanical watch and cannot be disassembled separately, and can only be replaced as a whole, resulting in a high cost and poor practicability. Content of the Utility Model
[0004] The utility model mainly provides a fine-tuning mechanism for the running accuracy of a mechanical watch, which is convenient for separately disassembling and replacing the fine-tuning rotating block, so as to reduce the maintenance cost.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a fine-tuning mechanism for the running accuracy of a mechanical watch, including a mechanical watch main body, a magic tape is fixed at the rear end of the mechanical watch main body, a water absorption pad is attached to the end of the magic tape away from the mechanical watch main body, a connecting sleeve is fixed at one end of the mechanical watch main body, an inserting column matching with the mechanical watch main body is arranged in the connecting sleeve, a fine-tuning rotating block is fixed at the end of the inserting column outside the connecting sleeve, and a clamping structure for clamping and limiting the inserting column is arranged in the connecting sleeve.
[0006] Compared with the prior art, the advantages and positive effects of the utility model are as follows:
[0007] In the present utility model, when it is necessary to disassemble the fine-tuning block, only need to pull the two pull plates in the opposite direction, drive the two connecting plates to move, so as to drive the two clamping columns to move out of the clamping cavity and contract into the inner cavity. At this time, the clamping columns no longer limit the insertion column, and the user can directly move out the insertion column and the fine-tuning block for separate replacement and repair, with lower cost and stronger practicability. Moreover, due to the oval setting of the clamping cavity, it will not affect the extraction of the insertion column a little bit for fine-tuning the mechanical watch body, with stronger practicability. During installation, only need to make the insertion column penetrate through the connecting sleeve and be arranged in the mechanical watch body. At this time, under the reset thrust of the spring, the clamping columns will enter the clamping cavities opened at both ends of the outer wall of the insertion column to limit it. In addition, through the setting of the magic tape, a water-absorbing pad can be attached to the rear end of the mechanical watch body, avoiding the dirt formed by the sweat on the user's wrist from sticking to the mechanical watch body, and only need to replace or clean the water-absorbing pad at intervals, with stronger practicability.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0015] Please refer to Figure 1 -Figure 5 , the present utility model provides a technical solution: a fine-tuning mechanism for the running accuracy of a mechanical watch, including a mechanical watch main body 1. A magic tape 4 is fixed to the rear end of the mechanical watch main body 1. One end of the magic tape 4 away from the mechanical watch main body 1 is attached to a water-absorbing pad 5. One end of the mechanical watch main body 1 is fixed with a connecting sleeve 6. An inserting post 7 matching the mechanical watch main body 1 is arranged in the connecting sleeve 6. One end of the inserting post 7 located outside the connecting sleeve 6 is fixed with a fine-tuning rotating block 8. A clamping structure 10 for clamping and limiting the inserting post 7 is arranged in the connecting sleeve 6. By the user pulling the fine-tuning rotating block 8 and then rotating the fine-tuning rotating block 8, the pointers in the mechanical watch main body 1 can be finely adjusted. This fine-tuning method belongs to the known technology of the existing mechanical watch main body 1 and belongs to a complete technical field, so it will not be described in detail herein. Through the setting of the clamping structure 10, the inserting post 7 and the fine-tuning rotating block 8 can be clamped and limited, which is convenient for the installation and disassembly of the inserting post 7 and the fine-tuning rotating block 8, reduces costs during maintenance, and has stronger practicability.
[0016] As Figures 1-5 shown, the clamping structure 10 includes inner cavities 1001 opened at both ends of the inner wall of the connecting sleeve 6. Springs 1002 are fixed on the inner walls of the two inner cavities 1001. One end of the two springs 1002 facing each other is fixed with a clamping post 1003. The two clamping posts 1003 both penetrate the inner cavity 1001 and are arranged in the inserting post 7. When it is necessary to disassemble the fine-tuning rotating block 8, only need to pull the two pull plates 15 in the opposite direction, drive the two connecting plates 14 to move, and thus drive the two clamping posts 1003 to move out of the clamping cavity 11 and contract into the inner cavity 1001. At this time, the clamping post 1003 no longer limits the inserting post 7, and the user can directly remove the inserting post 7 and the fine-tuning rotating block 8 and perform separate replacement and maintenance on them, with lower costs and stronger practicability. During installation, only need to make the inserting post 7 penetrate the connecting sleeve 6 and be arranged in the mechanical watch main body 1. At this time, under the reset thrust of the spring 1002, the clamping post 1003 will enter the clamping cavities 11 opened at both ends of the outer wall of the inserting post 7 to perform a limiting process on it.
[0017] As Figures 1-5 shown, clamping cavities 11 matching the clamping posts 1003 are opened at both ends of the outer wall of the inserting post 7. The shape of the clamping cavity 11 is oval. Due to the shape of the clamping cavity 11 being oval, it will not affect the inserting post 7 being pulled out a little to finely adjust the mechanical watch main body 1, with stronger practicability. This fine adjustment by pulling out the inserting post 7 a little and rotating it belongs to the public technical field of mechanical watch fine adjustment, so it will not be described too much herein.
[0018] As Figures 1-5As shown, limit blocks 12 are fixed to both ends of the outer wall of the clamping post 1003. Limit grooves 13 matching the limit blocks 12 are provided at both ends of the inner wall of the inner cavity 1001 within the connecting sleeve 6. Through the arrangement of the limit blocks 12 and the limit grooves 13, the position of the movement of the clamping post 1003 can be limited, preventing it from completely moving out of the inner cavity 1001, and the stability is stronger.
[0019] As Figures 1-5 shown, connecting plates 14 are fixed to both ends of the outer wall of the clamping post 1003. One end of each of the two connecting plates 14 penetrates through the connecting sleeve 6 and they are jointly fixed with a pulling plate 15. Movement grooves 16 matching the connecting plates 14 are provided at both ends of the outer wall of the connecting sleeve 6. Through the arrangement of the pulling plate 15, it is convenient to drive the clamping post 1003 to move.
[0020] As Figures 1-5 shown, connectors 2 are fixed to both ends of the outer wall of the mechanical watch body 1. Limit holes 3 are provided at both ends of the inner walls of the two connectors 2. An anti-slip sleeve 9 is fixed to the outer wall of the fine-tuning rotary block 8. Through the limit holes 3 provided at both ends of the inner walls of the connectors 2, it is convenient to clamp an external watch band. Through the arrangement of the anti-slip sleeve 9, the phenomenon of slipping when the fine-tuning rotary block 8 is rotated is avoided, and the stability is stronger.
[0021] Usage method and working principle of the present device: When the device is in use, by the user pulling the fine-tuning rotary block 8 and then through the rotation of the fine-tuning rotary block 8, the hands within the mechanical watch body 1 can be finely adjusted. This fine-tuning method belongs to the known technology of the existing mechanical watch body 1 and belongs to a complete technical field, so it will not be described in detail herein. When the fine-tuning rotary block 8 needs to be disassembled, just pull the two pulling plates 15 in the opposite direction to drive the two connecting plates 14 to move, thereby driving the two clamping posts 1003 to move out of the clamping cavity 11 and contract into the inner cavity 1001. At this time, the clamping posts 1003 no longer limit the insertion post 7, and the user can directly remove the insertion post 7 and the fine-tuning rotary block 8 for separate replacement and repair. The cost is lower and the practicability is stronger. Also, through the oval setting of the clamping cavity 11, it will not affect the removal of the insertion post 7 a little bit for fine-tuning the mechanical watch body 1, and the practicability is stronger. During installation, just make the insertion post 7 penetrate through the connecting sleeve 6 and be arranged within the mechanical watch body 1. At this time, under the reset thrust of the spring 1002, the clamping posts 1003 will enter the clamping cavities 11 provided at both ends of the outer wall of the insertion post 7 to limit it. In addition, through the arrangement of the magic tape 4, a water-absorbing pad 5 can be attached to the rear end of the mechanical watch body 1 to prevent dirt formed by the sweat on the user's wrist from sticking to the mechanical watch body 1. Just replace or clean the water-absorbing pad 5 at regular intervals, and the practicability is stronger.
[0022] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications to equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
