Description

Automatic rotating table

One, affiliated technical field:

The utility model relates to the equipment of having a dinner in a kind of daily living article, is a kind of automatic rotating table of the usefulness of having dinner specifically.

Two, background technology:

Dining table is various dining rooms, and the equipment of having dinner of indispensability in the family, the desktop of present most of dining tables all do not have the function of rotation automatically, brings inconvenience for the diner when eating dish; Though the dining table of some exclusive restaurant is provided with spinfunction, manual is many, few automatically.The main cause that automatic rotating table is few is the rotating machinery complexity, the cost height, rotating speed is uncontrollable, troublesome poeration, can not self-timing rotation, can not be artificial when rotated afterburning clockwise/counter-rotating/time-out, otherwise, fragile motor.

Three, summary of the invention:

For overcoming existing automatic rotating table complex structure, the cost height, rotary speed is uncontrollable, can not the self-timing rotation change, can not when electronic, quicken or counter-rotating by manpower, defectives such as stall provide a kind of simple in structure, and cost is low, can the self-timing rotation reach when electronic, manpower quickens, and the automatic rotating table of counter-rotating or the unlikely damage motor of stall is had a dinner being convenient for people to.

The utility model is that the technical scheme of solution usefulness that its technical problem is come is: design one and comprise fixedly desktop, rotating table top, whirligig, carrier base, motor, electric cabinet, the lazy Susan of driven wheel, be characterized in: 1. between rotating table top and carrier base, be fixed with rotating-table apparatus by screw, the cover plate of this rotating disc device and base center are equipped with through hole, and the upper and lower side of base central through hole all is provided with roller bearing and holds, the two bearings center is provided with a rotating shaft, the ball bearing of rotating disk upper end is provided with a traffic cycle gear, the top of this gear contacts with rotating disk cover plate bottom by friction plate, side at the rotating disk cover plate is provided with stop hole, to be fixed on the two bearings center and pass traffic cycle gear and friction plate by the limit screw in the hole, the rotating shaft of rotating disk cover plate through hole is fixed as one; Nibble on the flank of tooth of traffic cycle gear side and contain a driven wheel, this driven wheel directly is fixed on the main shaft of motor at a slow speed; Input at motor is provided with electric cabinet, is provided with control circuit in the electric cabinet, and this circuit has regularly produced/stopped signal, makes the every rotation of motor at a slow speed after 6～15 seconds, 5～15 seconds of stall; Realize that rotating table top rotates at a slow speed with the speed of per minute 0.5～1.5 circle.2. in the electric cabinet of jogging speed motor input terminals, be provided with the transformation rectification circuit, 220 volts of alternating currents of input are become 3～6 volts dc source, supply with timing circuit thereafter, to produce starting, stop signal regularly, this signal is put through the suction of power amplifier rear drive relay, the normal opened contact of this relay is serially connected in the power supply input circuit of motor at a slow speed, realizes the rotation of motor self-timing; 3. rotating table top and fixedly desktop be installed on the same horizontal plane, rotating table top is provided with a plurality of pit type hot pot stoves, hot pot stove is provided with cover plate, to guarantee that desktop is smooth without chafing dish the time.4. selected motor is the ac motor at a slow speed that per minute 6～15 changes.5. driven wheel and traffic cycle gear all adopt the straight-tooth engagement.

The beneficial effects of the utility model are: 1. directly be fixed on the cover plate of whirligig owing to rotating table top, be fixed with a rotating shaft in the rotation cover centre bore, this rotating shaft is passed on two ball bearings up and down that are fixed on base behind friction plate, the traffic cycle gear, the weight that not only can make desktop by bearings on base, can make rotating shaft not take place radially to rock again, the rotation that guarantees rotating table top not only easily but also steady, therefore can adopt low power Motor Drive, help reducing cost with easy to operate.2. owing to adopt motor at a slow speed, and drive the traffic cycle gear, avoided high-speed motor to need gearbox or deceleration device, help simplified structure, reduce cost with the direct geared on the motor main shaft.3. owing to be serially connected with regularly starting and stopping mechanism in the motor input circuit, can realize the purpose of self-timing rotation, be convenient to the human dish in each orientation of dining table.4. driven wheel and traffic cycle gear all adopt spur gear, have avoided in the past worm and gear or the difficult processing brought of angular wheel structure, and defectives such as expense height help reducing cost, and are convenient to penetration and promotion and use.
