Description

Movement limiting structure of calendar quick-setting mechanism

Technical Field

The utility model relates to a wrist-watch inner structure field, in particular to motion limit structure of mechanism is dialled soon to calendar.

Background

When the calendar movement is used for quickly dialing a day, the crown is rotated forwards, the transmission gear drives the quick dialing rod to move, the quick dialing rod calendar dialing head pushes one calendar ring tooth to enable the calendar ring to rotate by an angle along the anticlockwise direction, and then the calendar ring finally rotates by one tooth and is positioned under the elastic action of the day positioning rod to finish one-time quick dialing. When the calendar is quickly dialed next time, the quick-dialing rod is driven by the eccentric pin wheel, the rotating shaft part below the quick-dialing rod rotates clockwise, and the calendar dialing head above the quick-dialing rod slides to the right lower side along the calendar ring tooth, so that the dialing head enters between two teeth of the calendar ring to prepare for quickly dialing the calendar next time. In the process of the originally designed movement, when the calendar shifting head slides to the lower right along the calendar ring gear, the phenomenon that the shifting head rubs and touches the calendar ring gear is caused due to the difference of positioning tightness of the fast shifting rod and the eccentric pin wheel, so that the calendar ring generates clearance shake in the fast shifting process, and a defective product is formed.

Example 1:

referring to fig. 2 to 5, the movement limiting structure of the calendar quick-setting mechanism comprises a watch core main body 20 and a dial wheel assembly 10 arranged inside the watch core main body 20, wherein the dial wheel assembly 10 comprises inner teeth 101 of a calendar ring; a quick dial rod calendar shifting block 102 movably connected with a groove of a tooth part of the internal tooth 101 of the calendar ring; the eccentric pin wheel 107 that is connected through quick dial rod straight arm 104 with quick dial rod calendar shifting block 102 bottom, eccentric pin wheel 107 is connected with the quick dial over gear 106 meshing that sets up in one side, quick dial over gear 106 one side is connected with the meshing of quick dial vertical wheel 105, quick dial vertical wheel 105 one end is connected with the crown 108 that sets up in the outside of watch core main part 20 one side through the pivot, the contained angle department between calendar ring internal tooth 101 and the quick dial rod calendar shifting block 102, and it has the spacing bump 103 that sets up on the main board in watch core main part 20 to be located quick dial rod straight arm 104 middle position.

When a quick calendar-dialing operation is carried out, the crown 108 is pulled out to a first gear, the crown 108 is continuously rotated forwards, the quick dial vertical wheel 105 positioned on the shaft of the crown 108 rotates and drives the quick dial over wheel 106 to rotate, then the eccentric pin wheel 107 is sequentially driven to rotate, the quick dial rod with one end positioned on the eccentric pin wheel 107 is driven by the eccentric pin wheel 107 and limited by the track groove, the quick dial rod calendar dial 102 at the other end of the quick dial rod straight arm 104 pushes the calendar ring internal teeth 101 leftwards along the track groove, the calendar ring internal teeth 101 are pushed by the quick dial rod calendar dial 102 to stride across a tooth along the anticlockwise direction and are positioned, and then a quick calendar-dialing action for one day is completed. Because the quick-dial operation is continuous action, after the quick-dial calendar dial 102 completes one action, under the continuous rotation of the crown 108 and the continuous driving of the eccentric pin wheel 107, the quick-dial calendar dial 102 can continue to move along the track groove, and at this moment, the quick-dial calendar dial 102 can approach the inner teeth 101 of the calendar ring and slide to the lower right to retreat so as to enter the space between two inner teeth of the next calendar ring and start the next quick-dial calendar action. In the process that the quick dial lever calendar shifting block 102 slides and retreats along the inner teeth 101 of the calendar ring to the lower right, due to the existence of the limit salient points 103, the operation track of the quick dial lever calendar shifting block 102 changes under the interference action of the limit salient points 103, and the quick dial lever calendar shifting block can slide to the lower right and enter the next working interval by avoiding the inner teeth 101 of the calendar ring. Therefore, the calendar shifting block 102 of the quick-shifting rod is prevented from colliding with the inner teeth 101 of the calendar ring in the process of returning, and the realization of the quick-shifting continuous function is ensured.

Referring to fig. 4 and 5, the limit protrusions 103 are preferably integrally formed with the main plate in the movement body 20.

The direct injection molding has low cost and reliable action, well avoids the defect of quick dialing caused by the matching tightness difference between the rotating shafts of the quick dialing lever calendar dialing head 102 and the eccentric pin wheel 107, and improves the product percent of pass.

Referring to fig. 4 and 5, preferably, the limit bump 103 is a high-strength engineering plastic bump with a smooth surface and the same hardness as the straight arm 104 of the quick-setting lever.

In order to ensure that the friction between the limit salient point 103 and the straight arm 104 of the quick-pulling rod is as small as possible and avoid the generation of blockage, the limit salient point 103 is set to be a high-strength engineering plastic salient point with a smooth surface.

Referring to fig. 2-5, the limit bump 103 preferably has a structure of a shape like a Chinese character' tu

Referring to fig. 2-5, the bottom of the straight arm 104 of the quick-dial rod is preferably connected with the eccentric pin wheel 107 through a square positioning hole.

The working principle of the utility model is as follows:

the motion limiting convex points 103 are easy to process, are arranged on the main clamping plate and are directly formed by injection molding of the main clamping plate, are low in cost and reliable in action, well avoid the defect of quick shifting caused by the fact that the quick shifting rod and the rotating shaft of the eccentric pin wheel 107 have matching tightness difference, and improve the product percent of pass.

The above only be the preferred embodiment of the utility model discloses a not consequently restriction the utility model discloses a patent range, all are in the utility model discloses a conceive, utilize the equivalent structure transform of what the content was done in the description and the attached drawing, or direct/indirect application all is included in other relevant technical field the utility model discloses a patent protection within range.
