Description

Technical Field

[0001] The invention relates to the technical field of watches, in particular to a calendar quick-shift mechanism and a reed mechanism based on face gear transmission. Background Art

[0002] In watches, calendar quick-dial mechanisms and reed mechanisms are often used to control the adjustment of date and time. The application of calendar quick-dial mechanisms in watches provides users with the function of quickly adjusting the date. By rotating the calendar quick-dial mechanism, the calendar pointer can be easily adjusted to quickly switch dates to meet different time requirements. This mechanism makes the calendar function of the watch more practical and user-friendly, and improves the functionality of the watch. The reed mechanism is often used to limit the calendar quick-dial mechanism to achieve accurate date display of the watch.

[0003] The existing calendar quick-dial mechanism includes a calendar disk, a quick-dial gear, and a quick-dial piece. When the calendar is quickly dialed, the quick-dial piece rotates at a small angle under the drive of an external force to dial the quick-dial gear for a small angle rotation, driving the calendar ring to rotate and switch dates. The calendar quick-dial mechanism requires a large number of parts and relies too much on the use of spring pieces, which are easily damaged due to metal fatigue and have a short service life. The existing spring leaf mechanism includes a calendar disk, a positioning rod and a positioning lever spring. The positioning rod is usually made of 304 or 316 steel. The positioning rod is usually in direct contact with the ring teeth of the calendar disk and is stuck between the two ring teeth of the calendar disk, so that the calendar disk will not rotate easily. Since the positioning rod of the spring leaf mechanism is directly in contact with the ring teeth of the calendar disk, the resistance is large and the rotation is not smooth. Moreover, the positioning rod directly collides with the ring teeth of the calendar disk during rotation, and is easily damaged due to metal fatigue. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The calendar quick dial mechanism of the present invention can quickly adjust the calendar disk in the watch when needed, so that the date displayed on the watch is the correct date.

At the same time, the lever can slide and change its position in the connecting handle, which does not affect the rotation of the handle shaft. Instead, the effect of adjusting the spring mechanism is achieved through the movement of the lever. By changing the position of the lever in the connecting handle, the calendar quick-dial structure can have two adjustment modes. When the top ball on the lever is in the front slot, the pressure rod connected thereto retracts into the handle shaft, and the pressure rod does not contact the spring mechanism. The calendar quick-dial mechanism is normally restricted by the spring mechanism. When the top ball on the lever is in the rear slot, the pressure rod is in a pushed-out state, which will eliminate the restriction of the spring mechanism on the calendar disk, and the adjustment of the calendar quick-dial mechanism can be completed more quickly.

[0018] 3. The reed mechanism of the present invention limits the calendar disk to prevent errors in the calendar display. When necessary, the limit of the reed mechanism can be eliminated through the calendar quick-dial mechanism, and the date can be adjusted more quickly. The reed mechanism uses a zirconia bearing as the contact surface with the calendar disk ring teeth. The friction between the reed mechanism and the calendar disk is smaller, the rotation is smoother, the generation of metal debris is avoided, and the service life is extended.

[0019] 4. When rapid large-angle adjustment is required, the present invention can push the lever in the connecting handle to drive the pressure rod to move, thereby pushing the first piston on the gas storage block, so that the gas in the gas storage block is compressed, and the gas is used as a medium to move the second piston in the second air pipe to drive the transmission structure. When the second piston moves, the transmission structure can be used to drive the push bearing to generate pressure on the limit spring to change its shape, and the zirconia bearing at the end of the limit spring can be disengaged from the ring gear, so that the rotation of the calendar plate is not restricted, and the calendar quick-shifting mechanism can drive the calendar plate to quickly complete the adjustment.

[0020] 5. The present invention provides a spring for the rack in the transmission structure. The spring can form a damping for the movement of the rack and achieve the effect of resetting the rack and the pressure rod. According to the needs of the watch user, the position of the other end of the spring can be adjusted to change the difficulty of pressing the lever and the end. BRIEF DESCRIPTION OF THE DRAWINGS

The calendar quick dial mechanism uses the calendar disk 2 as the face tooth 3, and the calendar quick dial wheel 5 directly drives the calendar disk 2 to rotate. Compared with the existing calendar quick dial mechanism, it has the advantage of fewer parts.

The calendar quick-dial mechanism is subject to the normal restriction of the spring mechanism.
