Description

Low-noise quartz clock type timer

Technical Field

The utility model relates to a timing appliance, in particular to a quartz clock type timer with low noise.

Background

The timer is a commonly used timing tool; is beneficial to people to accurately master time and improve working efficiency. The conventional quartz clock type timer has a quartz clock type movement, a frame of the movement is formed by buckling and assembling an upper clamping plate and a lower clamping plate, a gear set is installed in the middle of the frame, and a coil component is fixed on one side of the frame. A driving gear in the gear set is coaxially connected with a rotor, and the rotor is driven by a variable magnetic field generated by the coil component to drive the driving gear to rotate; the driving gear drives a second gear, a third gear and a minute wheel which are sequentially meshed (a minute wheel shaft matched with the minute wheel is rotatably positioned on the lower clamping plate), wherein the second gear and the second gear are duplicate gears with small teeth; the second gear is rotated one sixth of a turn (i.e., the second hand is jumpingly swung on the dial at a scale spaced one second apart) by the driving gear once per second (each one half turn of the second) after the speed change of the second gear, and then stopped. The timer with the structure has the disadvantages that certain noise is generated during running (each time the rotor rotates and then suddenly stops, so that each pair of driven meshed gears generate impact due to rotation inertia, and certain noise is generated); will have certain influence on the life and work of part of consumers.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough among the above-mentioned background art, provide a quartz clock formula timer of low noise, this timer should have the characteristics that the accuracy is walked time, the noise is low.

The technical scheme of the utility model is that:

a low-noise quartz clock type timer comprises a quartz clock type movement; the quartz clock type movement drives a second wheel, a third wheel and a minute wheel which are sequentially meshed through a driving tooth coaxially connected with a rotor; the method is characterized in that: the quartz clock type movement is a quartz clock type movement with high-frequency output; three wheels and four wheels which are driven in sequence are also arranged between the second wheel and the second wheel; the two-wheel, the three-wheel, the four-wheel, the second wheel and the third wheel are all duplicate gears and are all in speed reduction transmission configuration.

The wheel shaft of the second wheel, the wheel shaft of the third wheel, the wheel shaft of the fourth wheel, the wheel shaft of the second wheel and the wheel shaft of the third wheel are arranged in parallel.

The wheel shaft of the second wheel, the wheel shaft of the third wheel, the wheel shaft of the fourth wheel, the wheel shaft of the second wheel and the wheel shaft of the third wheel are rotatably positioned on the clamp plate of the movement through bearings.

The utility model has the advantages that:

because of the quartz clock type movement with high frequency output, the rotor with motion output rotates continuously in one direction; therefore, the second hand (fixed on the second wheel shaft) driven by the second wheel in the gear set changes the conventional quartz clock type timer which swings once every second (the scale of one second swings on the dial once) into more than one second swings (the scale of one second rotates on the dial), and the impact generated between the gears is small, so that the generated noise is obviously reduced, and the influence on the user is correspondingly reduced. Is popular with users.

Detailed Description

The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.

The low noise timer shown in fig. 1 comprises a quartz clock type movement; the quartz clock type movement drives a second wheel, a third wheel and a minute wheel which are sequentially meshed through a driving tooth coaxially connected with a rotor; these are all similar to existing timers.

The utility model discloses an improvement lies in: the quartz clock type movement with high frequency output is changed into the originally adopted low-frequency quartz clock type movement (the coil component in the quartz clock type movement generates a magnetic field with the vibration frequency of 1Hz after being electrified, and the rotor needs to be driven to rotate for a half circle every time, so that larger pulse magnetic force is needed); three wheels and four wheels which are driven in sequence are also arranged between the second wheel and the second wheel; the two, three, four, second and third gears are all duplicate gears and are all in a speed reduction transmission configuration (i.e. a large gear in each duplicate gear is meshed with a small gear in the previous gear, and a small gear in each duplicate gear is meshed with a large gear in the next gear). Thus, tens of revolutions per second of the driving tooth can be reduced to one second of scale on the dial of the second hand rotating every second and one minute of scale on the dial of the minute hand rotating every minute. Moreover, although the quartz clock movement still makes half a turn per one second of the rotor, the pulse magnetic force per rotation is significantly reduced, and therefore the impact strength between the meshing gears in the gear train is significantly reduced, and therefore the noise emission is significantly reduced (in the conventional low-frequency quartz clock movement, at the moment when the pulse magnetic force disappears when the rotor driven by the larger pulse magnetic force makes half a turn per second, each pair of meshing gears is impacted by the rotation inertia, thereby generating a larger noise).

Preferably, the axle of the second wheel, the axle of the third wheel, the axle of the fourth wheel, the axle of the second wheel and the axle of the third wheel are arranged in parallel to each other to ensure that each pair of meshing gears are in a correct meshing state.

The wheel shaft of the second wheel, the wheel shaft of the third wheel, the wheel shaft of the fourth wheel, the wheel shaft of the second wheel and the wheel shaft of the third wheel are all rotatably positioned on the clamp plate of the movement, so that mechanical abrasion is reduced.

The utility model provides a quartz clock formula core of low frequency quartz clock formula core, high frequency output is conventional product, can purchase the acquisition outward.
