Abstract
The utility model discloses a middle clamping plate structure of a watch movement, comprising a middle clamping plate body. The middle clamping plate body is equipped with a pin tube, a second connecting wheel shaft hole, a reference column, a clutch clearance, an idler clearance, a minute wheel shaft hole, a data wheel shaft hole, a second wheel shaft hole, a rotor shaft hole and a transmission wheel shaft hole, wherein the pin tube corresponds with a screw hole in a main clamping plate, and is secured with a screw which penetrates through the screw hole; the second connecting wheel shaft hole is sleeved on one end of a second connecting wheel shaft, and the second connecting wheel shaft penetrating through the second connecting wheel shaft hole is embedded into a groove of a minute connecting wheel; the reference column penetrates through a reference column hole in the main clamping plate; and the middle clamping plate is positioned via the pin tube and the reference column. The middle clamping plate body is positioned between a second connecting wheel and the minute connecting wheel, so that in the transmission process the second connecting wheel and the minute connecting wheel do not influence each other, thereby improving the stability of the movement.
Description
Technical field
The utility model relates to a kind of middle clamp plate structure, relates in particular to a kind of timepiece movement middle clamp plate structure.
Background technology
in watchmaking, the fastening of inner structure is all take clamping plate as support, clamping plate are to coordinate to realize its positioning function by pilot hole disposed thereon with reference column on bottom plate, but the component on traditional middle clamp plate is less, make the location of middle clamp plate and bottom plate not in place, and the shortcoming that coordinates with each parts of movement, therefore on the fastening effect of each parts, certain impact is arranged, divide fifth wheel and second fifth wheel because being positioned in same rotating shaft, therefore might influence each other in transmission process, thereby also can affect the stability that whole wrist-watch rotates.
Summary of the invention
The purpose of this utility model is to provide a kind of each parts of better fixedly movement, improves the timepiece movement middle clamp plate structure of stability in the wrist-watch rotation process.
for achieving the above object, the utility model adopts following design proposal, it comprises the middle clamp plate body, described middle clamp plate body is provided with tapped foot, second fifth wheel axis hole and reference column, the fifth wheel axis hole was located between tapped foot and reference column in described second, described tapped foot is corresponding with the screw hole on bottom plate and tighten up with the screw that passes screw hole, one end of the sheathed second connection wheel shaft in described second fifth wheel axis hole top, connecting wheel shaft the second of passing second fifth wheel axis hole is embedded on minute fifth wheel groove below second fifth wheel axis hole, described reference column is located on the reference column hole of bottom plate.
Also being provided with clutch coupling on described middle clamp plate body keeps away a hole, back gear and keeps away a hole, minute wheel axis hole, crosses axle hole, second wheel axis hole, rotor shaft hatch and power wheel axis hole.
Described middle clamp plate body is ironware moulding or plastic shaping.
The utility model adopts above design proposal, by tapped foot and reference column are set on middle clamp plate, and tapped foot and reference column is arranged on second both sides of fifth wheel axis hole, realizes that middle clamp plate better locates; , make second fifth wheel and a minute fifth wheel be independent of each other in transmission process, thereby promote the stability of movement between second fifth wheel and minute fifth wheel by design middle clamp plate body; By design movement each parts on middle clamp plate keep away a hole and axis hole, make each parts of movement better fixing and be connected.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the utility model planar structure schematic diagram;
Fig. 2 is the local sectional structure schematic diagram that coordinates with middle clamp plate of timepiece movement;
Fig. 3 is the sectional structure schematic diagram of the utility model tapped foot.
Embodiment
as Fig. 1, Fig. 2, with shown in Figure 3, it comprises middle clamp plate body 1 the utility model, also be provided with on described middle clamp plate body 1 and comprise that clutch coupling keeps away a hole 11, back gear is kept away a hole 12, minute wheel axis hole 13, tapped foot 14, second, the fifth wheel axis hole 15, cross axle hole 16, reference column 17, second wheel axis hole 18, rotor shaft hatch 19, power wheel axis hole 20, fifth wheel axis hole 15 was located between tapped foot 14 and reference column 17 in described second, described tapped foot 14 is corresponding with the screw hole 21 on bottom plate 2 and tighten up with the screw 22 that passes screw hole, one end of the sheathed second connection wheel shaft 151 in described second fifth wheel axis hole 15 tops, connecting wheel shaft 151 second of passing second fifth wheel axis hole 15 is embedded on minute fifth wheel 3 grooves 31 below second fifth wheel axis hole 15, described reference column 17 is located on the reference column hole 23 of bottom plate 2.
Described middle clamp plate body 1 is ironware moulding or plastic shaping.
Claims (3)
