Abstract

The utility model provides an automatic tightening mechanical clock cassette mechanism with a photoelectric switch, which comprises a timing switch, wherein the timing switch is connected with a reduction motor, the reduction motor is connected with a winder, a coupling is arranged between the reduction motor and the winder, the front end of the winder is provided with a torque index hand, a clamping plate on a machine body is provided with two going barrels, the two going barrels are respectively provided with a sensing plate I, the clamping plate on the lower end of the going barrel is respectively provided with a photoelectric switch I, the coupling is provided with a sensing plate II, the lower end of a fixed plate of the reduction motor is provided with a photoelectric switch II, andthe photoelectric switch I and the photoelectric switch II are connected with the timing switch. The going barrels and the coupling are respectively provided with the sensing plates and the photoelectric switches, so when the going barrel is released for one circle, the motor rotates for one circle, thus always maintaining a given torque of the clockwork spring; therefore, the travel-time is verycorrect, and even after being utilized for a plurality of years, the torque of the clockwork spring is free from being weakened so as not to cause the stopping of the clock, or the torque of the clockwork spring is free from being increased so as not to cause the damage of the cassette mechanism.

Description

A kind of mechanical watch and clock movement that winds up automatically that has optoelectronic switch

Technical field

The utility model relates to the clockwork field, relates in particular to a kind of mechanical watch and clock movement that winds up automatically that has optoelectronic switch.

Background technology

In the background technology, the patent No. is in the patented technology of " 2008200212467,2008200212452 ", a kind of mechanical watch and clock movement that winds up is automatically disclosed respectively, though the movement of these two kinds of structures has all reached the purpose of winding up automatically, all exist used several years after, clockwork spring moment can weaken, inaccurate or stop clock when walking, or after long-term the use, clockwork spring moment strengthens the shortcoming that causes movement to damage.

Summary of the invention

The utility model provides a kind of mechanical watch and clock movement that winds up automatically that has optoelectronic switch, the mechanical watch and clock movement clockwork spring moment after long-term use of winding up automatically that has solved in the background technology can weaken, and inaccurate or clockwork spring moment strengthens the shortcoming that causes movement to damage when walking.

The technical solution of the utility model is achieved in that a kind of mechanical watch and clock movement that winds up automatically that has optoelectronic switch, comprise time switch, time switch links to each other with reducing motor, reducing motor links to each other with winder, establish shaft joint between reducing motor and the winder, the winder front end is established the moment pointer, establish two going barrels on the clamping plate on the body, establish sensing chip I on the going barrel respectively, on the clamping plate of going barrel lower end, establish optoelectronic switch I respectively, establish sensing chip II on the shaft joint, optoelectronic switch II is established in reducing motor fixed head lower end, optoelectronic switch I, optoelectronic switch II links to each other with time switch respectively.

The beneficial effects of the utility model are: the utility model is being respectively equipped with sensitive film and optoelectronic switch on the going barrel He on the shaft joint, when discharging once all motors, going barrel turns around, clockwork spring forever keeps certain moment like this, quite accurate when walking, even after using several years, clockwork spring moment can not stopped clock or clockwork spring moment and strengthens and cause movement to damage because of weakening to cause.

Part explanation: 1, optoelectronic switch I, 2, sensing chip I, 3, optoelectronic switch II, 4, sensing chip II, 5, winder, 6, going barrel, 7, reducing motor, 8, the moment pointer, 9, clamping plate, 10, time switch, 11, shaft joint, 12, the reducing motor fixed head.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described: a kind of mechanical watch and clock movement that winds up automatically that has optoelectronic switch, comprise time switch 10, time switch 10 links to each other with reducing motor 7, reducing motor 7 links to each other with winder 5, establish shaft joint 11 between reducing motor 7 and the winder 5, winder 5 front ends are established moment pointer 8, establish two going barrels 6 on the clamping plate 9 on the body, establish sensing chip I2 on the going barrel 6 respectively, on the clamping plate 9 of going barrel 6 lower ends, establish optoelectronic switch I1 respectively, establish sensing chip II4 on the shaft joint 11, optoelectronic switch II3 is established in reducing motor fixed head 12 lower ends, optoelectronic switch I1, optoelectronic switch II3 links to each other with time switch 10 respectively.

When operate as normal, going barrel 6 slowly rotates to right, the sensing chip I2 that is contained on the going barrel 6 turns right thereupon, when sensing chip I2 is close with optoelectronic switch I1, time switch 10 sends signal at once and gives motor, motor is started working, be contained in sensing chip II4 on the shaft joint 11 along with motor rotates, sensing chip II4 forwards to when close with optoelectronic switch II3, and motor quits work at once, and going barrel discharges once all motors and turns around like this, clockwork spring forever keeps certain moment like this, quite accurate when walking, even after using several years, clockwork spring moment can not stopped clock or clockwork spring moment and strengthens and cause movement to damage because of weakening to cause.
