Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example like Figure 1-12 As shown, an embodiment of the present invention provides a calendar and moon phase coaxial mechanism, including a base 1, on which a calendar and moon phase dial 2 and an adjustment component 3 for adjusting the calendar and moon phase dial 2 are provided. The calendar and moon phase dial 2 includes a moon phase ratchet 21, a calendar disc 22, a moon phase disc 23 and a calendar hand 24, which are coaxially stacked from bottom to top.

[0021] like Figure 1-12 As shown, in some embodiments, the base 1 includes a main clamping plate 11 and a secondary clamping plate 12 disposed on its top, the top of the secondary clamping plate 12 being provided with a circular groove 13 for mounting the calendar moon phase dial 2.

[0022] The main clamping plate 11 and the auxiliary clamping plate 12 are arranged in a layered layout for the adjustment component 3, resulting in a more compact structure and more rational use of space.

[0023] like Figure 1-12As shown, in some embodiments, the moon phase ratchet 21 is coaxially disposed inside the circular groove 13. The top end of the central shaft 25 of the moon phase ratchet 21 passes through the calendar disk 22 and is fixedly connected to the inside of the moon phase disk 23. The inside of the calendar disk 22 is provided with a bearing 26 that fits onto the surface of the central shaft 25. The top of the calendar disk 22 is provided with a groove. The moon phase disk 23 is embedded in the groove and the bottom of the moon phase disk 23 contacts the top of the bearing 26. The inside of the central shaft 25 is provided with a central shaft 27 whose top end is locked to the calendar hand 24 by a screw. The bottom of the calendar disk 22 is provided with a calendar ratchet 28.

[0024] The moon phase ratchet 21 is tightly fitted to the moon phase disk 23. The moon phase ratchet 21 drives the moon phase disk 23 synchronously through the central shaft 25. The calendar disk 22 is sleeved on the central shaft 25 through the bearing 26. The calendar disk 22 and the moon phase disk 23 are coaxially set through the central shaft 27 and the central shaft 25. The internal groove of the calendar disk 22 can be embedded into the moon phase disk 23, making the structure more compact. The calendar disk 22 and the moon phase disk 23 are separated by a gap through the bearing 26, so they will not affect each other. The bottom end of the central shaft 27 is fixed to the circular groove 13. The design of locking the central shaft 27 to the calendar needle 24 restricts the axial movement of the calendar disk 22 and the moon phase disk 23, ensuring assembly stability.

[0025] like Figure 1-12 As shown, in some embodiments, the bottom of the circular groove 13 is provided with a clearance hole 14, and one side of the circular groove 13 is also provided with a first mounting groove 15 and a second mounting groove 16, and one side of the main clamping plate 11 is provided with a third mounting groove 17 and a fourth mounting groove 18.

[0026] like Figure 1-12 As shown, in some embodiments, the adjustment component 3 includes a calendar adjustment mechanism 31, a moon phase adjustment mechanism 32, a calendar positioning mechanism 33, and a moon phase positioning mechanism 34.

[0027] like Figure 1-12 As shown, in some embodiments, the calendar adjustment mechanism 31 includes a calendar quick-set lever 311, a calendar quick-set bar 312, a calendar quick-set bar 313, and a calendar lever spring 314. One end of the calendar lever spring 314 is fixed to the top of the sub-clamp plate 12, and the calendar quick-set lever 311 is rotatably disposed on the top of the sub-clamp plate 12. One end of the calendar quick-set lever 311 extends to one side of the calendar ratchet 28, and the other end extends to one side of the calendar lever spring 314. The calendar quick-set lever 311 extends to one end of the calendar ratchet 28 and is provided with a calendar lever drive post 315. One end of the calendar quick-set bar 312 and the calendar quick-set bar 313 are respectively rotatably disposed at both ends inside the mounting groove 18. The other end of the calendar quick-set bar 312 extends to one side of the calendar lever drive post 315, and the other end of the calendar quick-set bar 313 extends to one side of the calendar quick-set bar 312.

[0028] By pressing button 41, the calendar quick dial bar 2 313 is activated, causing it to swing and one end to contact calendar quick dial bar 1 312. Calendar quick dial bar 1 312 then swings and one end contacts the calendar lever transmission column 315. The calendar lever transmission column 315 drives the calendar quick dial bar 311 to swing, causing one end of the calendar quick dial bar 311 to bend the low-pressure calendar lever spring 314, while the other end contacts the calendar ratchet 28 and rotates one tooth. After releasing button 41, the calendar lever spring 314 returns to its original position, contacting the calendar quick dial bar 311 to reset. The calendar quick dial bar 311, through the calendar lever transmission column 315, drives calendar quick dial bar 1 312, calendar quick dial bar 2 313, and button 41 to reset. Pressing button 41 again will drive the calendar ratchet 28 and calendar disc 22 to rotate again.

[0029] like Figure 1-12 As shown, in some embodiments, the moon phase adjustment mechanism 32 includes a moon phase quick-release lever 321, a moon phase quick-release bar 322, and a moon phase lever spring 323. One end of the moon phase lever spring 323 is fixedly disposed on the top of the main clamping plate 11, and the other end extends to one side of the mounting groove 16. One end of the moon phase quick-release lever 321 is rotatably disposed inside the mounting groove 16, and the other end extends to one side of the moon phase ratchet 21. The moon phase quick-release lever 321 has a moon phase lever transmission column 324 at one end extending to one side of the moon phase lever spring 323. One end of the moon phase quick-release bar 322 is rotatably disposed inside the mounting groove 317, and the other end extends to the side of the moon phase lever transmission column 324 away from the moon phase lever spring 323.

[0030] By pressing button 42, the moon phase quick-shift bar 322 is activated, causing it to swing and one end to contact the moon phase lever transmission post 324. The moon phase lever transmission post 324 then drives the moon phase quick-shift lever 321 to swing, causing one end of the lever 321 to contact the moon phase ratchet 21 and rotate one tooth. The ratchet 21 then simultaneously drives the moon phase disc 23 to rotate. During this process, the low-pressure moon phase lever spring 323 of the moon phase lever transmission post 324 bends. After releasing button 42, the spring 323 returns to its original position and contacts the moon phase lever transmission post 324, causing the moon phase quick-shift lever 321 to return to its original position. At the same time, the moon phase lever transmission post 324 drives the moon phase quick-shift bar 322 and button 42 to return to their original positions in sequence. Pressing button 42 again will drive the moon phase ratchet 21 and the moon phase disc 23 to rotate again.

[0031] like Figure 1-12 As shown, in some embodiments, the calendar positioning mechanism 33 includes a calendar positioning rod 331 and a calendar positioning spring 332. The calendar positioning spring 332 is installed inside the mounting groove 15. One end of the calendar positioning rod 331 is rotatably disposed inside the mounting groove 15, and the other end extends to one side of the calendar positioning spring 332. A calendar positioning shaft 333 is movably disposed at the bottom of the other end. The surface of the calendar positioning shaft 333 abuts against the surface of the calendar ratchet 28 under the action of the calendar positioning spring 332.

[0032] When the calendar ratchet 28 rotates, the ratchet teeth on its surface abut against the calendar positioning shaft 333, causing the calendar positioning shaft 333 to drive the calendar positioning rod 331 to swing and avoid it, so that the calendar positioning shaft 333 disengages from the tooth groove. During the swing, the calendar positioning rod 331 presses down the calendar positioning spring 332. When the calendar ratchet 28 rotates one tooth position, the calendar positioning shaft 333 is aligned with the tooth groove, and the calendar positioning spring 332 rebounds, causing the calendar positioning rod 331 to reset. The calendar positioning rod 331 then drives the calendar positioning shaft 333 to slide back into the tooth groove of the calendar ratchet 28, limiting its movement and preventing instability of the calendar ratchet 28. This ensures that each press of button 41 only causes the calendar ratchet 28 to rotate one tooth position, with a consistent rotation angle.

[0033] like Figure 1-12 As shown, in some embodiments, the lunar phase positioning mechanism 34 includes a lunar phase positioning rod 341 and a lunar phase positioning spring 342. The lunar phase positioning spring 342 is mounted on the top of the main clamping plate 11 and the top of the lunar phase positioning spring 342 extends into the interior of the clearance hole 14. One end of the lunar phase positioning rod 341 is rotatably disposed on the top of the main clamping plate 11, and the other end extends to one side of the lunar phase positioning spring 342. The top of the lunar phase positioning rod 341 extends into the interior of the clearance hole 14, and a lunar phase positioning shaft 343 is movably disposed on the top of the lunar phase positioning rod 341. The surface of the lunar phase positioning shaft 343 abuts against the surface of the lunar phase ratchet 21 under the action of the lunar phase positioning spring 342.

[0034] When the lunar phase ratchet 21 rotates, the ratchet teeth on its surface abut against the lunar phase positioning shaft 343, causing the lunar phase positioning shaft 343 to drive the lunar phase positioning rod 341 to swing and avoid it. This causes the lunar phase positioning shaft 343 to disengage from the tooth groove. During the swing, the lunar phase positioning rod 341 depressurizes the lunar phase positioning spring 342. After the lunar phase ratchet 21 rotates one tooth position, the lunar phase positioning shaft 343 is aligned with the tooth groove. The lunar phase positioning spring 342 rebounds and drives the lunar phase positioning rod 341 to reset. The lunar phase positioning rod 341 then drives the lunar phase positioning shaft 343 to slide back into the tooth groove of the lunar phase ratchet 21, limiting its movement and preventing instability of the lunar phase ratchet 21. This ensures that each press of button 242 only drives the lunar phase ratchet 21 to rotate one tooth position, with a consistent rotation angle.

[0035] like Figure 1-12 As shown, in some embodiments, a watch frame 4 is also included. The base 1 is disposed inside the watch frame 4 and is fixedly connected to the watch frame 4 by screws. One side of the watch frame 4 is provided with a first button 41 and a second button 42 corresponding to the positions of the second calendar quick dial 313 and the second moon phase quick dial 322, respectively. The first button 41 and the second button 42 are used to adjust the calendar disc 22 and the moon phase disc 23, respectively.

[0036] In summary, by using the central shaft 25 of the moon phase ratchet 21 to pass through the calendar disk 22 and extend into the moon phase disk 23, and in conjunction with the bearing 26 structure inside the calendar disk 22, the moon phase ratchet 21, calendar disk 22 and moon phase disk 23 are coaxially stacked, with a gap maintained between the moon phase disk 23 and the calendar disk 22. The transmission paths are independent and do not interfere with each other. Through the separately set calendar positioning mechanism 33 and moon phase positioning mechanism 34, it is ensured that only one tooth position is pushed each time, the rotation angle is consistent, the rotation is stable, the positioning is accurate, the overall structure has a reasonable layered layout, compact space, stable assembly, and reliable operation.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
