Abstract
The invention discloses a limiting device for a positioning rod of a date wheel or a week wheel in a watch, which is characterized in that a fixing column and a limiting column of the positioning rod of the date wheel or the week wheel are arranged on a bottom plate of a watch movement, one end of the positioning rod is hinged with the fixing column of the bottom plate, and the other end is provided with a protrusion, one side surface of the positioning rod is elastically connected with an elastic plate, and the other side surface leans against the limiting column. When the other side surface of the positioning rod leans against the limiting column, the protrusion of the positioning rod is matched with gear slots of the date wheel plate or the week wheel plate. By adopting the structure and utilizing the limiting column on the bottom plate of the watch movement, the matching degree between the protrusion of the positioning rod and the gear slots of the date wheel plate or the week wheel plate is controlled, the over-tightening butting between the protrusion of the positioning rod and the date wheel or the week wheel is avoided, and the timing function of the watch and accurate display of date and week are ensured.
Description
Technical field the present invention relates to a kind of wrist-watch parts, relates in particular to the stop means of the backstay of a kind of wrist-watch date wheel or week calendar wheel.
The wrist-watch of the existing middle and high level of background technology has calendar mostly and week is gone through display device, its date wheel or week calendar wheel under hour wheel drives, realize day rotating once or revolution once, date wheel or week calendar wheel are equipped with backstay in order to spacing.One end of the backstay of date wheel or week calendar wheel is provided with through hole, directly the one end is hinged on the bottom plate during installation, and the other end is provided with projection, and this projection is withstanding under the elastic force effect on the gear grooved of date wheel or week calendar wheel, carries out spacing to date wheel or week calendar wheel.As the patent No. is that ZL200520025917.3 a kind of is used for monthly calendar and the calendar mechanism interlock changes the watch structure of going through, and monthly calendar jumper spring 01 is with on the flexible gear grooved that is pressed in monthly calendar wheel 03 of monthly calendar backstay 02 1 ends projection 04.Because the elastic force dynamics that acts on the monthly calendar wheel 03 is not easy control, elastic force is too big, and projection can excessively hold out against monthly calendar wheel 03, influences wrist-watch timing transmission, thereby influences the wrist-watch operate as normal; Elastic force is too little, and projection 04 can not normally fix on the monthly calendar wheel 03, and backstay just can not be guaranteed spacing to monthly calendar wheel 03, and it is undesired to cause wrist-watch monthly calendar wheel 03 to be worked.
The summary of the invention the problem to be solved in the present invention provides a kind of projection of avoiding backstay excessively bear down on one date wheel or week calendar wheel, reduces the stop means of the backstay of the wrist-watch date wheel of wrist-watch mounting process difficulty or week calendar wheel.
For addressing the above problem, the stop means of backstay of the present invention is fixed leg and the limited post that is provided with the backstay of date wheel sheet or week calendar wheel sheet on the bottom plate of timepiece movement, one end of backstay and the fixed leg of bottom plate are hinged, its other end is provided with projection, one side of backstay and flexure strip resilient connection, wherein the another side of backstay leans against on the limited post, when the another side of backstay leaned against on the limited post, the projection of backstay cooperated with the gear grooved of date wheel sheet or week calendar wheel sheet.
Above-mentioned backstay leans against another side on the limited post and is provided with groove and cooperates with limited post.
One side of above-mentioned backstay and flexure strip resilient connection is an arc, and perhaps this side is provided with arc convex and flexure strip resilient connection.
The utility model adopts above structure, utilize the limited post on the bottom plate of timepiece movement, fitness between the projection of control backstay and the gear grooved of date wheel sheet or week calendar wheel sheet, avoid the projection of backstay excessively to hold out against date wheel or week calendar wheel, guarantee the accurate demonstration of clocking capability and the calendar and the Zhou Li of wrist-watch.The another side of backstay is provided with groove and cooperates with limited post, can improve the spacing accuracy of stop means.The face of backstay and flexure strip resilient connection adopts arc, can reduce the serviceability that work friction force between them is guaranteed backstay.This is simple in structure, and good limit effect, and the elastic force dynamics that has solved because of flexure strip is not easy control, to the calendar of wrist-watch with go through in week and show and even influence that the performance of timing causes.
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments for description of drawings.
Fig. 1 is the structural representation of stop means of the backstay of existing wrist-watch date wheel and week calendar wheel;
Fig. 2 is one of the structure synoptic diagram of stop means of the backstay of wrist-watch date wheel of the present invention and week calendar wheel;
Fig. 3 is two synoptic diagram of structure of stop means of the backstay of wrist-watch date wheel of the present invention and week calendar wheel.
Embodiment sees also figure or 2 shown in Figure 3, the present invention is provided with the backstay 4 of date wheel sheet 2 or week calendar wheel sheet 3 on the bottom plate 1 of timepiece movement, 5 fixed leg 12,13 and limited post 14,15, backstay 4, an end 41 of 5,51 respectively with the fixed leg 12 of bottom plate 1,13 is hinged, its other end is provided with projection 42,52, backstay 4, a side 43 of 5,53 respectively with flexure strip 6,7 resilient connection, backstay 4,5 with flexure strip 6, one side 43 of 7 resilient connection, 53 is arc, also can this side 43,53 are provided with arc convex 44,54 with flexure strip 6,7 resilient connection.Wherein the another side 45,55 of backstay 4,5 leans against on the limited post 14,15, and perhaps backstay 4,5 leans against another side 45,55 on the limited post 14,15 and is provided with groove 46,56 and cooperates with limited post 14,15.When the another side 45,56 of backstay 4,5 leaned against on the limited post 14,15, the projection 42,52 of backstay 4,5 cooperated with the gear grooved 21,31 of date wheel sheet 2, week calendar wheel sheet 3 respectively.
