Description

Push-button type non-positioning elastic quick-dialing machine core

Technical Field

The utility model belongs to the wrist-watch field specifically is a push button does not have location elasticity and dials core soon.

Background

Mechanical watches are often provided with quick-setting mechanisms in additional structures such as calendars, monthly calendars, weekly calendars, and the like. The quick-pulling mechanism of the pressing rod type is generally driven by parts such as the pressing rod, a positioning rod, a quick-pulling claw and the like, and the structure of the quick-pulling mechanism is fixed type quick-pulling. The dial wheel such as a calendar wheel and the like cannot rotate along with the time-division second hand in the normal operation of the movement, and the press rod only gives a force to rotate the dial wheel for a certain stroke at a certain time point. The calendar wheel and the like are fixed by the positioning rod firstly. For example, chinese patent document CN106842885A discloses "a modular multifunctional display mechanism" in 2017, 6/13, which includes a quick-dialing part, a positioning part, a transmission part and a functional display module, which are mounted on a base plate; and the quick dialing rod component in the quick dialing part, the positioning rod in the positioning component and the dialing cam in the transmission part respectively dial the function display module in time. The beneficial effects are that: because each function is manufactured into an independent module and the peripheral mechanism is matched with a relevant combination mechanism, the corresponding module can be flexibly replaced according to different function requirements, and the corresponding display function can be realized; and may be displayed at any point on the watch appearance as desired. In addition, a plurality of groups of display mechanisms can be installed to display multiple functions simultaneously, the display mechanisms improve the design efficiency and shorten the design period, and therefore the production cost is reduced. The quick-setting mechanism of the type of the press rod is only suitable for setting month, week, day wheel and the like because the set wheel is positioned, the set wheel does not rotate along with the core at ordinary times, and the positioning is released only when the set wheel is set. The other fast dial mechanism is mainly applied to a 12-hour wheel, a 0.5-hour wheel and the like which run synchronously along with the running of the movement, and the method which is often adopted is that a gear is driven by a stem, and the fast dial wheel is fast adjusted by a way of mutual meshing driving between the gear and the gear. The quick shift lever in the existing watch generally adopts a single-layer structure, and the stroke of the quick shift lever is controlled by an eccentric screw. The quick-pulling mechanism can only form gear engagement after the winding shaft is translated in the prior art, and directly pulls the minute wheel to realize, so that a pressing rod mode cannot be used. Under specific requirements, for example, when a countdown function needs to be integrated on a watch, the former quick-dialing mechanism cannot be realized, and the latter quick-dialing mechanism is poor in precision and lacks of practical use value.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

Example 1

As shown in fig. 1, 2 and 3, embodiment 1 is a push-button type non-positioning elastic quick-dial movement, which comprises a push rod 1 on the right side and a dial wheel 5 on the left side. In this example, the pressing end of the pressing rod 1 is located at the right side, the following end is located at the left side, and the middle part of the pressing rod 1 is fixed on the main clamping plate through a rotating shaft. The pressing rod 1 is also provided with a guide hole, the main clamping plate is provided with a guide post, and the guide hole is sleeved in the guide post, so that the pressing rod 1 rotates around the rotating shaft smoothly and stably. The follow-up end of the snap rod 1 is overlapped with the right end of the connecting rod 2. The middle part of the connecting rod 2 is fixed on the main clamping plate through a rotating shaft, the right end of the connecting rod is lapped with the follow-up end of the pressing rod 1, and the left end of the connecting rod is provided with a shifting block 3.

As shown in fig. 4, a dial mounting shaft 11 is provided at the left end of the connecting rod 2, and the dial 3 is sleeved on the mounting shaft 11 to be rotatable. A shifting block return spring 4 is connected between the connecting rod 2 and the shifting block 3. The dial return spring 4 is shaped like an L in plan view, having a long side and a short side, disposed around the dial mounting shaft 11. Wherein, the end part of the L-shaped short side is provided with a spring hook 41, the left end of the connecting rod 2 is provided with a spring mounting hole 12 in a through way, and the spring hook 41 is hooked in the spring mounting hole 12. The bottom surface of the shifting block 3 is provided with a groove for being matched with the L-shaped long edge of the shifting block reset spring 4. Therefore, the dial 3 can overcome the elastic force of the dial return spring 4 to swing around the dial mounting shaft 11, and can be pushed by the elastic force of the dial return spring 4 to return.

The dialled wheel 5 in this example is a 12 hour wheel provided with a circle of dialling teeth 51, the dialling teeth 51 are ratchet teeth adapted to the dialling direction, and the number is 120.

In the push-button type non-positioning elastic quick-dialing movement of the embodiment, the dialed wheel 5 can be used for timing by a time wheel in the countdown module. The dial wheel 5 rotates synchronously with the movement under normal conditions. When the hand-operated thumb wheel is used, the pressing end of the thumb lever 1 is pressed, force is transmitted to the left end of the connecting rod 2 through the thumb lever 1 and the connecting rod 2, the shifting head 3 moves downwards, the end part of the shifting head 3 and the shifting tooth 51 generate shifting action, and the wheel 5 rotates anticlockwise by a fixed angle, namely 5 tooth positions in the example. If the end of the shifting block 3 interferes with the shifting teeth 51, the shifting block 3 is deflected and swings under stress, avoids the tooth tips of the shifting teeth 51 and falls into the adjacent tooth grooves. After the poking is finished, the thumb press 1 is loosened, the poking head 3 can be driven by the connecting rod 2 to move upwards for resetting, and meanwhile, the poking head 3 can also reset to an initial angle under the elastic force of the poking head resetting spring 4 and is ready for next poking. Because the dial wheel 5 in this embodiment is a 12-hour wheel and the number of the dial teeth 51 is 120, the hour scale of 1/2 can be dialed by dialing 5 tooth positions every time the thumb press 1 is pressed, and dialing 1 hour requires 2 times of pressing the thumb press 1, that is, 24 times of pressing the button key can make the 12-hour wheel rotate for one circle.

Example 2

As shown in fig. 5, 6 and 7, the embodiment 2 is another push-button type non-positioning elastic quick-dialing movement. The position of the thumb press 1 of the embodiment is close to that of the thumb press 5, so that the connecting rod 2 is not required to transmit the 0.5 hour wheel, the number of the thumb press teeth 51 is 60, 2 tooth positions can be shifted when the thumb press 1 is pressed once, 1 minute scales can be shifted, namely, 1 minute can be shifted when the button is pressed once, and the 0.5 hour wheel can be rotated for one circle only by pressing the button key 30 times.

The same as in example 1.
