Abstract

The utility model discloses a radio controlled watch core capable of displaying with three hands, which mainly comprises a minute wheel component and a second wheel component, a second shaft of the second wheel component is mounted in a minute wheel pipe of the minute wheel component, the minute wheel pipe is sheathed outside a central pipe, and the second shaft is sheathed in an inner hole of the central pipe, thereby leading the second shaft and the minute wheel pipe to realize separation and friction through the central pipe, avoiding the mutual interference of second shaft and the minute wheel pipe, improving the transmission stability of a second wheel, meeting the high performance requirements of a radio controlled watch on the core, further realizing accurate time travelling and second setting of the radio controlled watch and realizing the display with the three hands.

Description

The Wave timepiece movement that can three pins shows

Technical field

The utility model relates to a kind of watch and clock movement, refers to a kind of Wave timepiece movement that can three pins shows especially.

Background technology

Wave timepiece is breakthrough because of its timing technology, becomes the third generation high-tech timing product behind stem-winder, quartz watch, and the Wave timepiece of existing various styles comes into the market, and provides people to select for use.

Wherein homemade pointer Wave timepiece movement is essentially the movement (movement is by external import) of non-independent research, so the cost height.And in homemade quartzy movement precision not high, major defect has 2 points: 1) the movement gear transmission structure is perfect inadequately, because second axle velocity of rotation is fast, length is long, and its relative spin friction with cannon pinion is big, and the friction force conference influences moment, Wave timepiece requires moment less again, require to exceed than general wristwatch a lot, thereby when causing Wave timepiece to be walked with inaccurate to second, can not be accurate to second; 2) electronic circuit board is by the terminal block on screw and bottom plate locking, and screw is to be locked on the bottom plate that plastics make, and screw is eaten up plastics easily and skidded, and causes the loose contact of switching between quartz and the electronics.Not high based on existing homemade quartzy movement transmission accuracy, can not be accurate to second, can't be applied to need possess in the middle of the Wave timepiece of high-precision requirement at all.Therefore, existing domestic pointer Wave timepiece, or be the import movement, the cost height if adopt homemade movement, then only is two pin movements, can only carry out two pins and show.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of Wave timepiece movement that can three pins shows, when it can solve cannon pinion and causes Wave timepiece to be walked greatly with a second axle friction with to inaccurate problem second.

Another technical matters to be solved in the utility model is to provide a kind of Wave timepiece movement that can three pins shows, it can solve that plastics bottom plate locking screw skids easily and the problem of the circuit loose contact that causes.

For solving the problems of the technologies described above, technical solution of the present utility model is:

A kind of Wave timepiece movement that can three pins shows, mainly comprise branch wheel assembly and second wheel assembly, axle second of second wheel assembly is installed within the cannon pinion of branch wheel assembly, described cannon pinion is sleeved on outside the pipe core, axle sleeve was contained in this pipe core endoporus in described second, and an order second axle separates friction with cannon pinion by pipe core.

Described pipe core riveted is fitted on the original middle clamp plate of movement, and is fixed on the bottom plate.

The terminal block position riveted of the original bottom plate of described movement is pressed with a screw pipe with internal thread, and the original electronic circuit board of movement is locked in the terminal block locking that makes in the internal thread of screw pipe on itself and the bottom plate by screw.

After adopting such scheme, the utility model need not be changed too big to original cassette mechanism structure, but set up a motionless pipe core between axle and the cannon pinion in second, thereby the direct friction of second axle and cannon pinion separately, the second wheel transmission stability is improved, reach the high performance requirements of Wave timepiece, with accurate, can realize that three pins show when Wave timepiece is walked second to movement.

In addition, the utility model is set up the screw pipe again and is fixed on the bottom plate, electronic circuit board with bottom plate on terminal block when locking, screw does not directly lock on the bottom plate that plastics are made, but be locked in the internal thread of screw pipe, so can solve the easy problem of slip of plastic latch screw, it is firm that circuit is connected, circuit is unimpeded not to cut off the power supply, thereby improves the stability of whole movement.

Description of drawings

Fig. 2 is a front elevation of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

What the utility model disclosed is a kind of pointer Wave timepiece movement, as shown in Figures 1 and 2, be preferred embodiment of the present utility model, it mainly is made up of bottom plate, train wheel bridge, coil block, stator piece, rotor wheel, power wheel, third wheel, second wheel assembly, pipe core assembly, branch wheel assembly, hour wheel module, hour wheel cover plate, except that pipe core, no longer describe in detail below the identical event of other structure with common movement.

One of improvement of the present utility model is: increase a pipe core 4, these pipe core 4 riveteds are fitted on the middle clamp plate 1, pipe core 4 and middle clamp plate 1 vertical riveted, and be fitted on the bottom plate 7.Second axle 31 of second wheel assembly 3 axially is sleeved in the endoporus of pipe core 4, little tooth 32 of second wheel on second shaft assembly 3 and the canine tooth engaged transmission of crossing wheel assembly 5, cross the little tooth and branch wheel assembly 2 canine tooth engaged transmission of wheel assembly 5, divide the tooth of wheel assembly 2 axially to be fitted on the cannon pinion 21, cannon pinion 21 axially is sleeved on outside the pipe core 4, so structure makes second axle 31 separate fully with cannon pinion 21, be that cannon pinion 21 transmission centers (being pipe core 4) are fixed body, axle 31 transmission centers second (being pipe core 4) also are fixed body, second axle 31 and cannon pinion 21 mutually noninterferes, it is firm to stablize, rational in infrastructure, thereby makes whole movement drive line more stable.

Two of improvement of the present utility model is: it increases the screw pipe 6 with internal thread, these screw pipe 6 riveteds are fitted on terminal block 8 positions of bottom plate 7, and terminal block on the bottom plate 78 and electronic circuit board (indicating among the figure) are locked in by screw in the internal thread of screw pipe 6 and lock.Because screw directly is not locked on the plastics bottom plate 7, has so solved the difficult problem that the plastic latch screw skids easily.It is firm that circuit connects, and circuit is unimpeded not to cut off the power supply, thereby improves the stability of whole electric wave movement greatly.
