Description

The timepiece movement of easy assembling

Technical field

The utility model relates to a kind of timepiece movement, is a kind of quartz watch movement specifically, and this movement is convenient to assemble hour wheel very much.

Background technology

Timepiece movement mainly is made up of bottom plate, bonnet and the train of installing between the two, stepper motor, circuit, trip(ping) lever etc., and its train is made up of transmission gears such as hour wheel, minute wheel, second wheel and third wheel, back gear, castle wheels, installs compact, accurate.At present, hour wheel is installed and will the time race on the bottom plate be covered with a hot tap hour wheel cover plate (tagger) in the Quartzcrystal watch movement, prevents that hour wheel from deviating from from movement; And hour wheel spring (thin slice that is similar to the elastic bending of the pad) elasticity on the wheel shaft is pushed down hour wheel when being contained in by one, and hour wheel guarantees the stable of hour wheel at axial float when preventing work.Hour wheel spring, this little part of hot tap hour wheel cover plate assemble up cumbersome, cause efficiency of assembling lower.

The utility model content

The purpose of this utility model is to provide a kind of timepiece movement of easy assembling, this movement make hour wheel installation and dismantle very convenient.

The utility model adopts following technical scheme: the timepiece movement of easy assembling, comprise bottom plate and hour wheel, the bottom plate middle part is race sometimes, race when hour wheel is positioned at, also comprise a trip(ping) lever, at the stationary positioned sheet of the oriented hour wheel groove center of the hour wheel groove edge projection of bottom plate, the elasticity spacer of stirring that the oriented hour wheel groove center of a side relative with stationary positioned sheet level protrudes.

A plurality of hour wheel perpendicular positioning reeds that are upturned can be arranged, to prevent that hour wheel is at axial float on the hour wheel of race when described being positioned at.

Can be oriented on the described hour wheel perpendicular positioning reed round dot of bottom plate outside projection, can form point with dial plate and contact, when reducing the hour wheel rotation and the frictional resistance of dial plate.

Described elasticity spacer can be an independently spring leaf that is fixed on the bottom plate, also can be made of the arc strip with the bottom plate one on the hour wheel trough rim on the bottom plate.

Described arc strip be with the time race concentric circular-arc, front end stretches out to the hour wheel groove center.

Described trip(ping) lever can adopt following structure: described trip(ping) lever comprises one corresponding to only only second arm and torque arm that bends towards the hook solid of ending arm direction second of second post of movement, second, the arm connecting portion had the third wheel that third wheel is installed that through hole is installed with only in torque arm, go out the web joint of a bending to extroversion ending second arm and torque arm junction, there is pilot hole the web joint end, and a straight hook-shaped push arm, the convex projection of stretching out of push arm corresponding to the movement arbor.

The timepiece movement of this easy assembling, hour wheel is located by stationary positioned sheet and the elasticity spacer to hour wheel groove center horizontal projection on the bottom plate, pushes the elasticity spacer aside and hour wheel is tilted a little and hour wheel can be taken out or pack into, and is easy to assembly quick.When can guaranteeing hour wheel axle center and bottom plate Surface Vertical location and prevent hour wheel work, hour wheel perpendicular positioning spring, and, has characteristics simple in structure, easy to assembly because be structure as a whole with hour wheel at axial float.

Embodiment

Be described further below in conjunction with the timepiece movement of the drawings and specific embodiments easy assembling of the present utility model.

As shown in Figure 1, race 2 when there is circle at bottom plate 1 middle part of Quartzcrystal watch movement, race 2 when hour wheel 5 was positioned at, the time race the edge protrude a stationary positioned sheet 6 to hour wheel groove center direction level, the hour wheel groove edge of the opposite side relative with its level have one with the time race concentric circular-arc elastic spring, leaf end inwardly stretches out a projection, forms elasticity spacer 4, and stationary positioned sheet 6, elasticity spacer 4 outside surfaces are concordant with bottom plate 1 outside surface.Stationary positioned sheet 6 and elasticity spacer 4 with the time hour wheel 5 in the race shelter from, prevent in the race 2 when hour wheel 5 is limited in that hour wheel from running out of, form the location.As long as the elasticity spacer 4 that can stir when dress hour wheel 5 (away from the direction of hour wheel) is backward pushed aside, hour wheel 5 is tilted slightly put into facing to the direction of stationary positioned sheet 6, decontrol the elasticity spacer 4 that can stir again and get final product.This structure decrease hot tap hour wheel cover plate, not only reduced number of spare parts, and made things convenient for assembling.

Three reeds that are upturned on hour wheel 5 surfaces constitute hour wheel perpendicular positioning reed 3, and hour wheel perpendicular positioning reed 3 ends have 31, three hour wheel perpendicular positionings of round dot reed 3 of projection to be structure as a whole with hour wheel 5.Hour wheel perpendicular positioning reed 3 can form DISCRETE ELASTIC SUPPORTS with the round dot 31 of dial plate (omitting among the figure) by projection and contact, prevents hour wheel 5 at axial float, and wheel shaft is vertical with dial plate during assurance.Adopt this structure can save an original hour wheel spring, not only made things convenient for assembling, and reduced cost because of part reduces.

As shown in Figure 2, trip(ping) lever on the movement comprises that one is ended second arm 11 and a torque arm 15 that bends towards the hook solid of ending arm 11 directions second, second, arm 11 connecting portions had third wheel that through hole 12 is installed with only in torque arm 15, go out the web joint of a bending to extroversion with torque arm 15 junctions ending second arm 11, there is pilot hole 13 the web joint end, this end also is connected with a straight hook-shaped push arm 14, push arm is convex stretch out a projection 14 '.Its principle of work as shown in Figure 3, when walking to show, the projection on the trip(ping) lever push arm 14 is withstood by arbor 26, it ends second arm 11 and keeps released states with second post 21 that ends on the wiring board,

third wheel

22 and 27 engagements of minute wheel pivot tooth, rubber-like draws the tension of 15 arms, normally walks table.When the needs second hand stop is dialled pin, arbor 26 is drawn out to state shown in Figure 4, outwards pull out because of arbor 26 this moment, withstand on the elasticity of the trip(ping) lever torque arm 15 on the reference column 25, trip(ping) lever is rotated counterclockwise around locating shaft 23, and third wheel on the trip(ping) lever 22 disengages with minute wheel pivot tooth 27, and the second post 21 of ending that ends then on second arm 11 and the wiring board contacts, stop to walk table, to dial the pin timing.Be pressed into arbor 26 after timing finishes to state shown in Figure 3, second, a post 21 separated with only to end second arm 11, and

third wheel

22 and 27 engagements of minute wheel pivot tooth, began to continue to walk table.The trip(ping) lever of this structure is a sheet substantially, has advantage simple in structure, reliable operation.
