AI Technical Summary

Problems solved by technology

Traditionally, this kind of quick dial mechanism can only be achieved by using the winding shaft to move in translation to form gear meshing, and directly dial the minute wheel to achieve it, and the press lever method cannot be used.
Under specific requirements, for example, when the countdown function needs to be integrated on the watch, the former quick-dial mechanism cannot be realized, and the latter quick-dial mechanism has poor accuracy and lacks practical use value

Embodiment 1

[0020] Such as figure 1 , figure 2 , image 3 The shown embodiment 1 is a push-button non-positioning elastic quick-dial movement, which includes a pressing rod 1 on the right side and a dialed wheel 5 on the left side. In this example, the pressing end of the press bar 1 is located on the right, and the follower end is located on the left, and the middle part of the press bar 1 is fixed on the main splint by a rotating shaft. The press bar 1 is also provided with a guide hole, and the main splint is designed with a guide post, and the guide hole is sleeved in the guide post, so that the press bar 1 is smooth and stable when it rotates around the rotating shaft. The follow-up end of the pressing rod 1 is overlapped with the right end of the connecting rod 2. The connecting rod 2 is also fixed on the main splint with the rotating shaft in the middle part, and the right end is overlapped with the follower end of the press bar 1, and the toggle head 3 is installed on the left...

Embodiment 2

[0025] Such as Figure 5 , Figure 6 , Figure 7 The shown embodiment 2 is another button-type non-positioning elastic quick-dial movement. In this example, the position of the pressing rod 1 is close to the dialed wheel 5, so there is no need to design the connecting rod 2 to transmit the 0.5 hour wheel. The number of shifting teeth 51 is 60, so each pressing the pressing rod 1 can move 2 gears , you can turn the 1-minute scale, that is, each time you press the button, you can quickly dial 1 minute, so you need to press the button 30 times to make the 0.5-hour wheel rotate one circle.

[0026] The rest are the same as embodiment 1.

Abstract

The invention discloses a button type positioning-free elastic quick-shifting movement, which comprises a pressing rod and a shifted wheel, wherein a shifting block capable of rotating is installed atthe follow-up end of the pressing rod, and a shifting block reset spring is further connected between the shifting block and the follow-up end of the pressing rod; and a circle of poking teeth are arranged on the poked wheel, and when the pressing rod is pressed, the end of the poking head and the poking teeth on the poked wheel form a poking relation. The button type positioning-free elastic quick-shifting movement has the beneficial effect that gears synchronously running along with running of the machine core can be accurately shifted.

Description

technical field [0001] The invention belongs to the field of watches, in particular to a button-type non-positioning elastic quick-dial movement. Background technique [0002] Mechanical watches are often equipped with quick-dial mechanisms in additional structures such as calendars, monthly calendars, and weekly calendars. Among them, the push rod type quick dial mechanism is generally driven by parts such as a push rod, a positioning rod, and a quick dial claw. This structure is a fixed quick dial. During the normal operation of the movement, the dialed wheels such as the calendar wheel will not rotate together with the hour, minute and second hands. Only at a certain point in time will the push rod give a force to make it rotate a certain stroke. The track wheels such as the calendar wheel are first fixed by the positioning rod. For example, the Chinese patent document CN106842885A disclosed "a modular multifunctional display mechanism" on June 13, 2017, including a qui...
