Description

Technical Field

[0001] The present application relates to the technical field of watches, and in particular to a bidirectional calendar quick-dial mechanism for a mechanical watch. Background Art

[0002] At present, when adjusting the date of a mechanical calendar watch, the hour hand needs to be adjusted for 24 hours to adjust the date by one day, which is quite troublesome. In addition, the adjustment frequency is high due to factors such as different months and stopwatches. Therefore, most calendar watches are usually equipped with a calendar quick-dial mechanism. The structure of the commonly used calendar quick-dial mechanism is as follows: Figure 15 As shown, the stem has three gears. The clutch lever, clutch wheel, and rocking component a are controlled by the gear puller. The floating setting wheel engages with the vertical wheel, the intermediate wheel, and the calendar quick-setting wheel, respectively, to achieve the winding, hand-setting, and calendar quick-setting functions. The three working positions of the floating setting wheel are positioned by the rocking component a, which requires high standards, a complex structure with multiple axial parts, and a complex structure. Furthermore, the date can only be adjusted in one direction. For example, if the date is offset by one day, the date ring must be rotated nearly a full rotation to complete the adjustment, which is very inconvenient. Therefore, a calendar quick-setting mechanism with a simple overall structure and bidirectional adjustment of the date ring is needed to address the above issues. Utility Model Content

[0003] In order to solve the problem in the above background technology that the existing calendar quick dial mechanism has a complex structure and only has a one-way date adjustment function, which makes date adjustment inconvenient, the present application provides a two-way calendar quick dial mechanism for a mechanical watch.

[0004] The bidirectional calendar quick-dial mechanism of a mechanical watch provided in this application adopts the following technical solution:

[0005] A two-way calendar quick-dial mechanism for a mechanical watch, comprising:

[0006] Rotatable date ring;

[0007] The calendar quick dial wheel is connected to the calendar ring in a transmission manner and is configured to drive the calendar ring to rotate when the calendar quick dial wheel rotates;

[0008] The stem is axially slidably connected to the center hole of the calendar quick dial wheel;

[0009] Among them, the calendar quick dial wheel and the stem are provided with a locking structure for achieving synchronous rotation of the two. When the stem moves to the specified position so that the calendar quick dial wheel and the stem are relatively locked, the calendar quick dial wheel can be driven to rotate synchronously by rotating the stem forward or reverse, thereby realizing bidirectional rotation of the calendar ring.

[0010] By adopting the technical scheme, the axial movement of the stem shaft is used to realize the gear switching of the mechanical watch, when the stem shaft moves axially to the specified position, the locking structure is used to make the stem shaft rotate synchronously with the calendar quick paster, and then the power is transmitted to the calendar ring through the rotation of the stem shaft, so that the calendar ring rotates to achieve the date adjustment effect; and the stem shaft can rotate forward and reverse during the rotation, so that the effect of bidirectional rotation of the calendar ring is realized, thereby improving the convenience and rapidity of date adjustment.

[0011] Optionally, the locking structure comprises a key groove formed in the center of the calendar quick paster, and a locking part arranged on the stem shaft and capable of being inserted into the key groove, after the locking part is inserted into the key groove, the stem shaft and the calendar quick paster rotate synchronously.

[0012] By adopting the technical scheme, during the process of not adjusting the date, the locking part and the key strip are in a state of mutual separation, and the rotation of the stem shaft will not drive the calendar quick paster and the calendar ring to rotate, in this state, the user can perform the winding or needle operation; when the calendar needs to be adjusted, the stem shaft moves axially, so that the locking part on the stem shaft is inserted into the key groove of the calendar quick paster, so that the two are connected in synchronous rotation, and then under the condition that the stem shaft rotates, the calendar quick paster and the calendar ring can be driven to rotate, thereby achieving the purpose of adjusting the date.

[0013] Optionally, the rotation center line of the calendar quick paster is perpendicular to the rotation center line of the calendar ring; and the calendar quick paster and the calendar ring are meshed and connected.

[0014] By adopting the technical scheme, the power transmission is realized by the calendar quick paster and the calendar ring which are perpendicular to each other without changing the position and direction of the stem shaft, so that the modification cost can be saved; the calendar quick paster and the calendar ring adopt the gear combination mode for power transmission, and have the advantages of good power transmission effect and high precision.

[0015] Optionally, the circumferential direction of the calendar ring is provided with end face teeth or outer circle teeth which are meshed with the calendar quick paster.

[0016] By adopting the technical scheme, the power transmission can be realized between the calendar quick paster and the calendar ring in the case that the teeth are arranged on the end face of the calendar ring or on the outer circle, and the application range is wide.

[0017] Optionally, the clutch wheel is axially slidably connected to the stem shaft and synchronously rotatably connected to the stem shaft.

[0018] The clutch wheel is axially slidably connected to the stem shaft and synchronously rotatably connected to the stem shaft.

[0019] The end face helical gear is rotatably connected to the stem shaft, and the clutch wheel can engage with the end face helical gear when the clutch wheel slides to the limit position along the first direction of the stem shaft axis;

[0020] The needle setting wheel is rotatably installed in the watch interior and is arranged at the other end of the clutch wheel away from the end face helical gear, and the clutch wheel can engage with the needle setting wheel when the clutch wheel slides to the limit position along the second direction of the stem shaft axis.

[0021] By adopting the above technical scheme, the clutch wheel can engage with the end face helical gear and the needle setting wheel under different conditions through axial movement of the clutch wheel. The end face helical gear is connected to the winding mechanism in the watch interior, and when the clutch wheel engages with the end face helical gear, the watch is in the winding working state. After the stem shaft is rotated, the clutch wheel rotates, and then the clutch wheel drives the end face helical gear to rotate. The end face helical gear transmits power to the winding mechanism, thereby realizing the winding work of the watch. The needle setting wheel is connected to the needle setting assembly, and when the clutch wheel engages with the needle setting wheel, the watch is in the needle setting working state. After the stem shaft is rotated, the clutch wheel rotates, and then the clutch wheel drives the needle setting wheel to rotate. The needle setting wheel transmits power to the needle setting assembly, thereby realizing the needle setting work of the watch.

[0022] Optionally, the watch further comprises:

[0023] The compression spring is fixed in the watch interior, and a plurality of notches are sequentially arranged on one side of the compression spring from top to bottom.

[0024] The pull catch is rotatably installed in the watch interior, and a first protrusion matched with the notches of the compression spring is arranged on one end of the pull catch, and a second protrusion is arranged on the other end of the pull catch, and the second protrusion can extend into the clamping groove arranged on the outer diameter of the stem shaft.

[0025] The clutch rod is rotatably installed in the watch interior, and the end of the clutch rod is in contact with the upper end of the pull catch, and the middle part of the clutch rod can be arranged in the annular groove in the middle of the clutch wheel, so that the clutch rod can drive the clutch wheel to move along the stem shaft when the clutch rod swings.

[0026] By adopting the above technical scheme, different gear positions of the stem shaft can be switched by arranging the pull catch in different notches of the compression spring. When the pull catch is arranged in different notches, the pull catch can drive the clutch rod to swing, so that the clutch rod swings to different positions, and the clutch rod drives the clutch wheel to move to different positions. The movement of the clutch wheel has three conditions: one is that the clutch wheel engages with the end face helical gear, and the watch is in the winding gear at this time; one is that the clutch wheel engages with the needle setting wheel, and the watch is in the needle setting gear at this time; and one is that the clutch wheel is arranged between the end face helical gear and the needle setting wheel. At this position, the locking part on the stem shaft is inserted into the key groove of the calendar quick setting wheel, and at this time, the watch is in the calendar quick setting gear, and the date can be adjusted by rotating the stem shaft.

[0027] Optionally, a clutch lever spring is also included, which is installed in the watch and has one end abutting against the clutch lever, so that the clutch lever drives the clutch wheel to be in a state of meshing with the end face bevel teeth under normal conditions.

[0028] By adopting the above technical solution, the clutch lever is driven by the clutch lever spring to always swing in one direction. On the one hand, the clutch lever and the gear pull are always in contact. In this state, gear switching can be achieved by controlling the position of the gear pull; on the other hand, when the force driving the gear pull disappears, the clutch lever spring can drive the clutch lever to a reset state.

[0029] Optionally, it also includes a calendar positioning rod, which is rotatably installed inside the watch near the inner wall of the calendar ring. An elastic part is connected to the calendar positioning rod, which can make the end of the calendar positioning rod abut against the inner wall of the calendar ring; the inner wall of the calendar ring is evenly provided with thirty-one internal teeth.

[0030] By adopting the above technical solution, the front end of the calendar positioning rod can be stuck in the inner teeth during the rotation of the calendar ring, so that the date can be displayed more completely on the dial during the date adjustment process, and it also helps to quickly adjust the date to the appropriate position.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] (1) The utility model has a reasonable design structure, which replaces the complex swing components in the traditional calendar quick-dial mechanism, making the overall calendar quick-dial mechanism have the advantage of a simpler structure;

[0033] (2) The present invention sets a calendar quick dial wheel inside the watch in engagement with the calendar ring, and can achieve synchronous rotation connection between the stem and the calendar quick dial wheel by adjusting the gear position of the stem, thereby achieving the effect of two-way date adjustment of the calendar ring.

[0061] The application will be further described in detail below with reference to the accompanying drawings.

[0062] Embodiment I,

[0063] As Figure 1-12 shown, the embodiment of the application discloses a bidirectional calendar quick drive mechanism of a mechanical watch, which comprises a calendar ring 1, a calendar quick drive wheel 2, a stem 3, a clutch wheel 4, an end face bevel gear 5, a drive wheel 6, a compression spring 7, a pull catch 8, a clutch rod 9, a clutch rod spring 10 and a calendar setting lever 11. Wherein:

[0064] The calendar ring 1 is a rotatable calendar ring 1, which is installed in the inside of the mechanical watch, one of the end faces is a dial face, and a date scale or date number is arranged around the center thereof; specifically, in this example, the circumferential direction of the calendar ring 1 is provided with an end face tooth 101 which is engaged with the calendar quick drive wheel 2.

[0065] The calendar quick drive wheel 2 is in transmission connection with the calendar ring 1, and is arranged to drive the calendar ring 1 to rotate when the calendar quick drive wheel 2 rotates; specifically, the rotation center line of the calendar quick drive wheel 2 is perpendicular to the rotation center line of the calendar ring 1; the calendar quick drive wheel 2 is in engagement connection with the calendar ring 1, that is, the circumferential direction of the calendar quick drive wheel 2 also has a gear, which is engaged with the end face tooth 101 of the calendar ring 1, so as to realize power transmission.

[0066] The stem 3 is in axial sliding connection in the center hole of the calendar quick drive wheel 2, more specifically, the stem 3 is in axial movable connection in the watch, and the end thereof extends to the outside position of the watch; in this example, the calendar quick drive wheel 2 only has the freedom of rotation in the inside of the watch, and the axial direction thereof is in a locked state, and the stem 3 can move axially and also can rotate in the watch.

[0067] Wherein, the calendar quick drive wheel 2 and the stem 3 are provided with a locking structure for realizing synchronous rotation of the two, when the stem 3 moves to a specified position to make the calendar quick drive wheel 2 and the stem 3 relatively locked, the stem 3 can drive the calendar quick drive wheel 2 to rotate synchronously by forward rotation or reverse rotation, and then realize bidirectional rotation of the calendar ring 1.

[0068] Specifically, the locking structure comprises a key groove 201 which is opened in the center of the calendar quick drive wheel 2, and a locking part 301 which is arranged on the stem 3 and can be inserted into the key groove 201, after the locking part 301 is inserted into the key groove 201, the stem 3 and the calendar quick drive wheel 2 realize synchronous rotation.

[0069] More specifically, the locking portion 301 on the stem shaft 3 is in the shape of a square structure in cross section, and can also be designed into other regular polygonal structures according to actual conditions, as long as it can be inserted into the key groove 201 and drive the calendar quick dial 2 to rotate.

[0070] The clutch wheel 4 is axially slidably connected to the stem shaft 3 and synchronously rotatably connected to the stem shaft 3; in this example, the stem shaft 3 is provided with a mounting position 303 for mounting the clutch wheel 4 at a position on the inner wall of the watch, the mounting position 303 is in the shape of a square structure in cross section, and the central hole of the clutch wheel 4 is also in the shape of a square structure, and the clutch wheel 4 is sleeved on the mounting position 303 of the stem shaft 3, so that the clutch wheel 4 can move along the axis of the stem shaft 3 and synchronously rotate with the stem shaft 3.

[0071] The end face helical gear 5 is rotatably connected to the stem shaft 3, and when the clutch wheel 4 slides to the limit position in the first direction along the axis of the stem shaft 3, the clutch wheel 4 can engage with the end face helical gear 5; specifically, the end face helical gear 5 is used to connect the winding mechanism inside the watch, and the winding mechanism can tighten the mainspring inside the watch to achieve the purpose of storing energy; in the normal state, the end face helical gear 5 rotates relative to the stem shaft 3, and the end face helical gear 5 does not rotate, when the clutch wheel 4 engages with the end face helical gear 5, rotating the stem shaft 3, the clutch wheel 4 rotates, thereby driving the end face helical gear 5 to rotate, thereby realizing the winding action; wherein the winding mechanism is a conventional component inside the mechanical watch in the prior art, and its structure and principle will not be described in detail here.

[0072] The pin wheel 6 is rotatably mounted inside the watch and is provided at the other end of the clutch wheel 4 away from the end face helical gear 5, and when the clutch wheel 4 slides to the limit position in the second direction along the axis of the stem shaft 3, the clutch wheel 4 can engage with the pin wheel 6; the pin wheel 6 is mainly connected to the pin setting assembly inside the watch, for example Figure 7-9 As shown, when the pin wheel 6 rotates under the drive of the clutch wheel 4, it can transmit power to the pin setting assembly, and finally realize the operation of setting the hour and minute hands, wherein the pin setting assembly is a conventional component inside the mechanical watch in the prior art, and its structure and principle will not be described in detail here.

[0073] The compression spring 7 is fixed inside the watch, and a plurality of notches 701 are sequentially provided on one side of the compression spring 7 from top to bottom; the compression spring 7 is in a fixed state inside the watch, and in this example, the number of notches 701 is three.

[0074] A puller 8 is rotatably installed in the watch interior, and has a first protrusion 801 at one end thereof that matches the notch 701 of the compression spring 7, and a second protrusion 802 at the other end thereof that can extend into the clamping groove 302 at the outer diameter of the stem 3. Specifically, the first protrusion 801 and the second protrusion 802 are respectively located at both sides of the rotation center of the puller 8, and axial movement of the stem 3 can drive the second protrusion 802 to move, so that the puller 8 rotates around its own rotation center. After rotation, the first protrusion 801 can be clamped into the corresponding notch 701 of the compression spring 7, so as to achieve the positioning effect of the puller 8. Since there are three notches 701 in total, the stem 3 also has three gears when working, which respectively correspond to the winding gear shown in Figure 7 , the needle setting gear shown in Figure 8 , and the fast-pulling gear shown in Figure 9 .

[0075] A clutch lever 9 is rotatably installed in the watch interior, and has an end that is in contact with the upper end of the puller 8, and the middle part of the clutch lever 9 can be placed in the annular groove 401 in the middle of the clutch wheel 4, so that the clutch lever 9 can drive the clutch wheel 4 to move along the stem 3 when the clutch lever 9 swings. The clutch lever 9 is mainly driven to swing by the puller 8, and when the clutch lever 9 swings, it can drive the clutch wheel 4 to axially move on the stem 3, so as to achieve the purpose of meshing of the clutch wheel 4 with the end face helical gear 5, meshing of the clutch wheel 4 with the needle setting wheel 6, or idling of the clutch wheel 4.

[0076] Specifically, a clutch lever spring 10 is installed in the watch, and one end of the clutch lever spring 10 abuts against the clutch lever 9, so that the clutch lever 9 drives the clutch wheel 4 to be in meshing with the end face helical gear 5 in the normal state.

[0077] Specifically, a calendar positioning lever 11 is rotatably installed in the watch interior close to the inner wall of the calendar ring 1, and an elastic member is connected to the calendar positioning lever 11. The elastic member can be a tension spring or a torsion spring, so as to make the end of the calendar positioning lever 11 abut against the inner wall of the calendar ring 1, and the elastic member can make the end of the calendar positioning lever 11 abut against the inner wall of the calendar ring 1. The inner wall of the calendar ring 1 is uniformly provided with thirty-one inner teeth 103.

[0078] The bidirectional calendar fast-pulling mechanism of the mechanical watch is in an initial state, in which the stem 3 is in an un-pulled-out state, i.e., the stem 3 is in the winding gear, as shown in Figure 7 . The stem 3 can make the first protrusion on the puller 8 be located at the uppermost notch 701 of the compression spring 7, and the clutch lever 9 is located in the normal state under the action of the clutch lever spring 10, as shown in Figure 7The rightmost extreme position shown in the figure, in this position, the clutch wheel 4 is engaged with the end bevel gear 5, and the clutch wheel 4 is driven to rotate by rotating the stem 3, the clutch wheel 4 drives the end bevel gear 5 to work, and the end bevel gear 5 drives the winding mechanism to work, thereby realizing the winding operation.

[0079] When the handle 3 is pulled outward, Figure 8 As shown, in this state, the stem 3 is in the needle gear. As the stem 3 is pulled out, the pull gear 8 can be driven to rotate, so that the first protrusion on the pull gear 8 is stuck in the notch 701 at the middle position of the compression spring 7. At the same time, the pull gear 8 exerts a force on the clutch lever 9, so that the clutch lever 9 swings, driving the clutch wheel 4 to move as shown in FIG. Figure 8 The left extreme position shown in the figure moves and engages with the needle setting wheel 6. At this time, the handle 3 is rotated to realize the needle setting operation.

[0080] When the stem 3 is pulled out again, Figure 9 As shown, in this state, the stem 3 is in the fast shift gear. As the stem 3 continues to be pulled outward, the pull gear 8 is driven to continue to rotate, so that the second protrusion on the pull gear 8 is stuck in the notch 701 at the bottom of the compression spring 7. At this time, the clutch lever 9 is disengaged from the engagement with the needle wheel 6 under the action of the clutch lever spring 10, so that the clutch lever 9 drives the clutch wheel 4 to a position between the needle wheel 6 and the end face bevel tooth 5, and in this state, the locking portion 301 on the stem 3 is inserted into the keyway 201 of the calendar fast dial wheel 2. When the stem 3 is rotated, the calendar fast dial wheel 2 can be driven to rotate, and the calendar fast dial wheel 2 can be used to drive the calendar ring 1 to rotate to achieve date adjustment. In this state, the stem 3 can rotate forward or reverse, so that the calendar ring 1 can also rotate clockwise or counterclockwise, achieving the effect of fast date adjustment.

[0081] Example 2

[0082] like Figure 13-14 As shown, the difference between this embodiment and the above embodiment is that the date ring 1 is provided with external circular teeth 102 in the circumferential direction thereof, which mesh with the date quick dial wheel 2 , and can be used to meet the requirements of different application scenarios of the date ring 1 .

[0083] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
