Description

A kind of actuating mechanism of mechanical timing dissemination wristwatch
Technical field
The present invention relates to a kind of actuating mechanism of mechanical timing dissemination wristwatch, particularly relate to and a kind ofly there is water resistance and improve the actuating mechanism of the mechanical timing dissemination wristwatch of structural behaviour.
Background technology
Having the mechanical watch of time reporting function, be commonly called as " asking table ", is that the striking mechanism that gives the correct time by being arranged on movement inside realizes giving the correct time and gets function ready.Ask that the timing dissemination actuating mechanism of table needs to process a through hole in case side wall, meet the outside power transmission to internal part.Now, watchcase internal machine core directly contacts with air, cannot reach requirement that is dust-proof, waterproof.Chinese patent CN101846964A discloses a kind of proof mechanism of water of mechanical timing dissemination wristwatch, and as shown in Figures 1 to 3, one end of stage clip 1 is arranged on stage clip positioning head, the other end press connect button 2, connect button 2 by pull bar 3, dial 4 connections; One end of seal box 5 is provided with tie-rod sealing circle 6, is sealed between seal box 5 and solid machine circle by seal box cushion rubber 6; Seal box 5 is fixed in the special impression of Gu Jiquan by securing member; The shape of tie-rod sealing circle and the shape of pull bar 3 suitable; Pull bar 3 enspheres in seal box 5 through block, tie-rod sealing, and by the slipper seal of tie-rod sealing circle; Tie-rod sealing circle compresses by block, the gap between airtight pull bar and seal box; One end of shifting block coordinates with pull bar through the fluting on seal box, and the shifting block other end starts plate and contacts with giving the correct time, when pull bar drive pulling block moves, and pulling block and give the correct time to start between plate and have an effect, the startup of giving the correct time of control wrist-watch.In above-mentioned patent, the proof mechanism of water of mechanical timing dissemination wristwatch reaches requirement that is dust-proof, waterproof substantially, but there is following shortcoming: 1. on water-tight, and between seal box and solid machine circle is special-shaped cushion rubber, and the difficulty of processing and adaptation is large, poor universality, and cost is high; O-ring seal between seal box and pull bar needs on seal box, process a groove and lays cushion rubber, and part difficulty of processing is large, and operation is many, once go wrong or cannot be adaptive after processing, all can cause waste.2. stage clip plays the effect that mechanism is resetted, and same bounce can not effectively control also to cause the rigid damage between part, reduces serviceable life.3. group with connect the adaptive position of detain and be designed to fan-shaped, sharp processing difficulty is high, and consistance is poor, checks difficult.Often after assembling occurring dialling promoting not in place, or the problem such as in pushing course, between part, to block.4., because seal box volume is comparatively large, restriction is defined to the size of overall wrist-watch.
Summary of the invention
Problem to be solved by this invention is, overcomes the shortcoming of prior art, provides the actuating mechanism of the mechanical timing dissemination wristwatch that a kind of water resistance is good, structure is simple, volume is little, cost is low.
The technical solution adopted in the present invention is: a kind of actuating mechanism of mechanical timing dissemination wristwatch, comprises, and dials handle, adapter sleeve, draws core, waterproof sealing pipe, contiguous block, shifting block, Gu Jiquan, draws core support, stage clip, waterproof apron, movement give the correct time startup plate; Described Gu Jiquan is formed with groove, draws core support to be fixed in the groove of Gu Jiquan; Described adapter sleeve is connected and fixed with the square end of drawing one end of core with group handle respectively and is integrated, and draws the other end of core to be free end; Described drawing on core is set with waterproof sealing pipe and stage clip, draws core pass contiguous block and draw core support; Described stage clip is arranged in the length range of support; Described contiguous block is fixedly mounted on the indentation, there of drawing and core being formed, and draws core to pass contiguous block, and described contiguous block and shifting block are connected, and described shifting block and movement give the correct time and start plate and contact or depart from, and the outside two ends up and down of described solid machine circle are provided with waterproof apron.
Also include block; Described block is provided with reed; Block is connected in support the indentation, there of drawing core, described in draw core to pass block.
Be provided with waterproof apron in described waterproof sealing pipe and pipe ring washer, described that pipe back-up ring is clamped on waterproof sealing pipe is inner, and waterproof apron is limited in the annular groove of waterproof sealing pipe; Described cushion rubber slipper seal of drawing in core and waterproof sealing pipe.
Described shifting block is secondary, and secondary two orientation starting plate of giving the correct time with movement respectively contact.
Described adapter sleeve comprises adapter sleeve upper cover, adapter sleeve lower cover and coupling shaft; Described adapter sleeve upper cover is formed with the junction of dialling handle the groove received and dial the square one end of being with circular hole; Describedly draw core ribbon to have one end of through hole to be connected axle to be fixed in the groove of adapter sleeve upper cover, coupling shaft is spacing to drawing core to carry out; Adapter sleeve upper cover and adapter sleeve lower cover will be dialled handle by firm and be drawn core to connect as one.
The invention has the beneficial effects as follows: due to the waterproof sealing pipe being provided with waterproof apron sealing between Gu Jiquan and watchcase and draw core to install at Gu Jiquan with inside, not only block outside and inner contact from outermost end, and seal again from inside, realize the effect of dust and water protection, ensure the normal work of wrist-watch.In addition, the block installed additional has cushioned the power of bounce-back, decreases loosening of rigid damage between part and parts.This startup structure eliminates seal box, wrist-watch is accomplished in standard size little and thin, and one-piece construction is simple, easy to process, precision degree.
