Description

Technical Field

[0001] This utility model relates to the field of watchmaking machinery, specifically a device for evenly distributing the winding force of a watch spring. Technical Background

[0002] In traditional mechanical clocks, the mainspring winding is usually operated using a simple rotating shaft structure. However, this traditional structure has obvious defects in actual use: due to the lack of an effective winding force adjustment mechanism, the winding force is prone to fluctuation during the winding process and cannot be evenly distributed. When the winding force is too large, it may cause the mainspring to be overstretched, which will not only shorten the service life of the mainspring, but may also cause failures such as breakage due to excessive internal stress. When the winding force is too small, it will cause the mainspring to be loosely wound, resulting in insufficient power to the clock, which will affect the accuracy of the clock and cause it to run too fast or too slow. In addition, the disassembly and maintenance process of traditional devices is relatively cumbersome, requiring the use of various tools and consuming more time and manpower, which is not conducive to later inspection and replacement of parts.

[0003] Therefore, designing a spring winding device that can evenly distribute winding force and is easy to assemble and disassemble is of great practical significance. Utility Model Content

[0004] The purpose of this invention is to provide a device for evenly distributing the winding force of a watch spring, so as to solve the problems of uneven winding force and inconvenient disassembly and assembly in the prior art.

[0005] A device for evenly distributing the winding force of a watch spring includes a spring coil, a protective component, a winding force adjustment component, and a quick-release component. The spring coil is disposed inside the protective component, the winding force adjustment component is disposed at the top of the protective component, and the quick-release components are symmetrically disposed at both ends of the protective component.

[0006] As a further description of the above technical solution:

[0007] The protective assembly includes a protective shell, with a bearing plate bolted to the top of the shell. The bearing plate has a cover plate at its top, and a groove with an arc shape is provided at the top of the cover plate.

The limiting plate is set on the top of the bearing plate via a rotating column, and the limiting plate is adapted to the gear two.

[0008] As a further description of the above technical solution:

[0009] The top of the limiting plate is provided with a limiting post, which is adapted to gear one. The top of the limiting plate is provided with a pushing post on the side near the limiting post, which is adapted to the cover plate slide groove. One end of the limiting plate is provided with a spring one, and one end of the spring one is provided with a fixing block. The bottom end of the fixing block is fixedly connected to the top of the bearing plate.

[0010] As a further description of the above technical solution:

[0030] As attached Figure 1 To be continued Figure 4The present invention provides a device for evenly distributing the winding force of a watch spring, comprising a spring coil 1, a protective component 2, a winding force adjustment component 3, and a quick-release component 4.

[0031] The mainspring coil 1 is located inside the protective component 2. Its purpose is to provide comprehensive protection for the mainspring coil 1 and prevent it from being affected by external factors. The winding force adjustment component 3 is located at the top of the protective component 2. This connection method facilitates the adjustment of the winding force of the mainspring coil 1 inside the protective component 2 through the winding force adjustment component 3. The quick-release components 4 are symmetrically arranged at both ends of the protective component 2. This layout allows for the fixation and quick disassembly / reassembly control of the structure of the protective component 2 from both ends.

[0032] Example 1

[0033] Specifically, the protective component 2 includes a protective shell 22, the top of which is connected to a support plate 23 by bolts. The bolt connection ensures the firmness of the connection between the protective shell 22 and the support plate 23, and facilitates disassembly and maintenance later. The top of the support plate 23 is provided with a cover plate 21, which can shield and protect the components at the top of the support plate 23 to prevent dust and impurities from entering. The top of the cover plate 21 is provided with a sliding groove, which is arc-shaped. The arc-shaped sliding groove provides a suitable trajectory for the subsequent movement of the push column 36, ensuring that the push column 36 can move smoothly.

[0034] Example 2

[0035] Based on Example 1, in order to further ensure that the winding force of the mainspring is always in a uniform and stable state, a winding force adjustment component is provided at the top of the protective component.

[0036] Specifically, the winding force adjustment component 3 includes a rotating shaft 32, which penetrates the middle of the protective component 2. This penetration allows the rotating shaft 32 to extend deep into the protective component 2 and connect with the mainspring coil 1, while also facilitating external control of the mainspring coil 1 via the rotating shaft 32. A knob 31 is provided at the top of the rotating shaft 32, which provides a convenient point for the operator to apply force, making it easy for the operator to rotate the rotating shaft 32. The bottom end of the rotating shaft 32 is connected to the mainspring coil 1, and this connection method allows the rotation of the rotating shaft 32 to directly drive the mainspring coil 1 to perform a winding action.

[0037] Among them, the outer end of the rotating shaft 32 is provided with a gear 33, which rotates synchronously with the rotating shaft 32, laying the foundation for subsequent cooperation with the gear 34 to transmit power and adjust the speed. The bottom side of the gear 33 is provided with a gear 34, which meshes with the gear 33 and can transmit the rotational power of the gear 33. At the same time, the speed is adjusted by the gear transmission ratio. A limiting plate 35 is provided on one side of the gear 34. The limiting plate 35 is set on the top of the bearing plate 23 through a rotating column. The setting of the rotating column allows the limiting plate 35 to rotate flexibly around the rotating column. The limiting plate 35 is adapted to the gear 34 and can limit the rotation of the gear 34, thereby controlling the rotation of the gear 33 and the rotating shaft 32.

[0038] In addition, a limiting post 37 is provided at the top of the limiting plate 35. The limiting post 37 is adapted to the gear 33. When the limiting plate 35 rotates, the limiting post 37 can cooperate with the tooth groove of the gear 33 to further limit the rotation speed and force of the gear 33 and ensure uniform winding force. A pushing post 36 is provided on the top of the limiting plate 35 near the limiting post 37. The pushing post 36 is adapted to the slide groove of the cover plate 21. The pushing post 36 moves in the slide groove and can guide the limiting plate 35 to rotate along a specific trajectory to ensure the stability and accuracy of the movement of the limiting plate 35.

[0039] Furthermore, one end of the limiting plate 35 is provided with a spring 38, and one end of the spring 38 is provided with a fixing block 39. The bottom end of the fixing block 39 is fixedly connected to the top end of the bearing plate 23. The fixing block 39 provides a fixed support for the spring 38, while the spring 38 provides elastic tension to the limiting plate 35, so that the limiting plate 35 can always maintain the matching state with the gear 34 and the gear 33, ensuring the stability of the limiting effect.

[0040] Specifically, the quick-release assembly 4 includes a bracket 41, which is symmetrically arranged at both ends of the cover plate 21. The bracket 41 provides installation support for other components of the quick-release assembly 4. The bottom of the bracket 41 is provided with a limiting block 42, which is located at both ends of the protective shell 22. The cooperation between the limiting block 42 and the protective shell 22 can initially limit the position of the bracket 41. One end of the bracket 41 is provided with a fixing post 43, and one end of the fixing post 43 is provided with a pull plate. The pull plate facilitates the operator to pull the fixing post 43. The fixing post 43 is used to achieve a fixed connection between the bracket 41 and the protective shell 22.

[0041] The fixed column 43 is provided with a limiting plate 44 at its outer end. The limiting plate 44 can limit the movement range of the fixed column 43 and prevent the fixed column 43 from falling off the bracket 41. A second spring 45 is provided on the side of the fixed column 43 near the limiting plate 44. The second spring 45 provides elastic thrust to the fixed column 43, so that the fixed column 43 can be tightly locked in the limiting position, ensuring the firmness of the connection between the bracket 41 and the protective shell 22.

[0042] In addition, a sealing gasket is provided at the penetration point between the rotating shaft 32 and the protective component 2. The sealing gasket is made of nitrile rubber. The inner ring of the sealing gasket is tightly fitted to the outer wall of the rotating shaft 32. Nitrile rubber has good sealing performance and wear resistance. The tight fit can effectively prevent the leakage of lubricating oil inside the device and the entry of external impurities, ensuring the normal operation environment of the internal components of the device.

[0043] Furthermore, the outer wall of the knob 31 is provided with anti-slip texture. The anti-slip texture is distributed in an oblique cross pattern. The oblique cross pattern can increase the friction between the hand and the knob 31, prevent the operator's hand from slipping when rotating the knob 31, and improve the convenience and stability of operation.

[0044] Furthermore, the inner wall of the protective shell 22 is provided with a buffer pad layer. The buffer pad layer is made of silicone material and its surface is in contact with the outer wall of the mainspring 1. The silicone material has good elasticity and cushioning performance. The setting of being in contact with the outer wall of the mainspring 1 can play a buffering and protective role for the mainspring 1, reduce the impact of external vibration and impact on the mainspring 1, and reduce the noise of the mainspring 1 during operation.

[0045] It should also be noted that the mainspring coil in this application can be a regular-sized mechanical watch mainspring coil, a miniature precision watch mainspring coil, a high-torque mechanical watch mainspring coil, etc. Figure 1 In this embodiment, a conventional-sized mechanical watch mainspring is used as an example for description. Of course, other types of watch mainsprings can also adopt a similar structure, which will not be elaborated on later.

[0046] Understandable, Figure 1 The diagram only schematically illustrates some of the components of the force uniform distribution device; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, the force distribution device can also include, compared to... Figure 1 More or fewer parts.

[0047] In actual use, the operator holds the knob 31 with his hand. Since the outer wall of the knob 31 has diagonally crisscrossed anti-slip textures, it can effectively prevent the hand from slipping. The operator rotates the knob 31, which drives the rotating shaft 32 to rotate. The rotating shaft 32 passes through the middle of the protective component 2, and its bottom end is connected to the mainspring 1. Therefore, the rotation of the rotating shaft 32 will directly drive the mainspring 1 to wind, storing power for the watch to run.

[0048] During the rotation of the rotating shaft 32, the gear 33 at the outer end of the rotating shaft 32 rotates synchronously with the rotating shaft 32. The gear 33 meshes with the gear 34 on the bottom side, thereby driving the gear 34 to rotate together. The limiting plate 35 on one side of the gear 34 is set on the top of the bearing plate 23 through the rotating column, and the limiting plate 35 is adapted to the gear 34. The rotation of the gear 34 will exert a force on the limiting plate 35, causing the limiting plate 35 to tend to rotate around the rotating column.

[0049] The limiting post 37 at the top of the limiting plate 35 is adapted to the gear 33. When the gear 33 rotates, the limiting post 37 will continuously contact and cooperate with the tooth groove of the gear 33, which will play a certain role in hindering and limiting the rotation of the gear 33, thereby limiting the rotation speed of the rotating shaft 32. At the same time, the pushing post 36 at the top of the limiting plate 35 moves in the arc-shaped groove of the cover plate 21, providing guidance for the rotation of the limiting plate 35 and ensuring the stable operation of the limiting plate 35.

[0050] When the limiting plate 35 rotates, the spring 38 at one end of the limiting plate 35 will deform. The fixing block 39 at one end of the spring 38 will provide fixed support for the spring 38. The elastic force generated by the spring 38 will pull the limiting plate 35, so that the limiting plate 35 always maintains the matching state with the gear 34 and the gear 33, thereby continuously adjusting the rotation force of the gear 33 and the rotating shaft 32, ensuring that the force is uniform when the rotating shaft 32 drives the mainspring coil 1 to wind, and realizing the uniform distribution of the mainspring winding force.

[0051] When internal components of the device need to be inspected or maintained, the operator pulls the pull plate at one end of the fixing column 43 in the quick-release assembly 4. The pull plate moves the fixing column 43 outward, and the limiting plate 44 at the outer end of the fixing column 43 moves accordingly, squeezing the second spring 45 at the outer end of the fixing column 43, causing the second spring 45 to undergo compression deformation. When the fixing column 43 moves out of the limiting engagement state with the protective shell 22, the cover plate 21 can be removed from the top of the support plate 23, and then the components such as the spring coil 1 and the winding force adjustment assembly 3 inside the protective assembly 2 can be inspected and maintained. After the inspection and maintenance is completed, the pull plate is released, the second spring 45 returns to its deformation, pushes the fixing column 43 to reset, and re-establishes the limiting engagement with the protective shell 22, fixing the cover plate 21 to the top of the support plate 23, thus completing the assembly of the device.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
