Abstract

The utility model relates to an automatic rotating dining table, which comprises a rotating tabletop, a fixed tabletop and a mechanical drive system fixed under the tabletop. By using an energy mechanism driven by springs to generate spring force moment which rotates the tabletop and a centrifugal speed limiter to control the rotating speed, the mechanical drive system makes the rotating speed stable and uniform. The utility model has the advantages of simple structure, high safety and convenient manufacture.

Description

Automatic rotating dining table

The utility model is a kind of lazy Susan, is to drive rotation with mechanical driving device, belongs to the improvement design of lazy Susan.

Present existing lazy Susan is by rotating table top, fixedly desktop connects by slewing equipment, the lazy Susan of manually rotating, also having be by be placed in rotary desktop and fixedly the friction of the grinding disk between the desktop rotate the also moving rotation of armrest; More advanced is to adopt the driven by motor rotation, but cost is higher, and electricity consumption, uses inconvenient.

The purpose of this utility model is that manufacturing is a kind of easy to use, and cost hangs down non-electric machine driving lazy Susan.

The utility model operation principle is to produce enough clockwork spring moment and drive desktop and rotate by being fixed on mechanical driving device under the desktop, and by speed adjusting gear control velocity of rotation, makes the desktop rotation that remains a constant speed.

The utility model, by the revolution desktop, fixedly desktop and slewing equipment constitute, slewing equipment is by being the iea of power with the clockwork spring, transmission mechanism, output mechanism and speed adjusting gear four parts composition.

Accompanying drawing is a structural representation of the present utility model.

Iea is by barrel gear 18, goes up bar gear 13, non-return spring 14, is with the last bar handle 15 of clutch to constitute.Barrel gear 18 is made up of barrel and bar lid two parts, clockwork spring 16 and bar axle 17 are housed in the barrel, clockwork spring 16 the inners have a square hole to be enclosed within on the bar axle hook, clockwork spring 16 outer ends have hook to collude on the driving wheel on barrel inwall, clockwork spring 16 preferably adopts two can reduce the barrel gear diameter, but also can adopt clockwork spring one by one, bar axle 17 is installed in the barrel gear centre, have on the bar axle 17 and hang the hook that clockwork spring is used, clockwise direction shakes the last bar handle 15 of band clutch during operation, the last bar gear 13 drive barrel gears 18 that are installed on the bar Handle axis tighten clockwork spring 16, produce enough clockwork spring moment, by transmission mechanism clockwork spring moment is passed to output mechanism, at this moment, non-return spring 14 plays non-return effect.

Transmission mechanism is made up of driven wheel 5, third wheel 4, drive 3, mistake tooth mill pinlon 19, worm gear 20, worm screw 21, driven wheel 5 is installed on the bar axle 17, mesh with crossing tooth mill pinlon 19 on the one hand, by third wheel 4 and drive 3 engagements that are installed on the worm-wheel shaft, drive worm and gear and pay rotation again; With output gear 12 engagements, clockwork spring moment is passed to output mechanism on the one hand.

Output mechanism be location bearing 11 is housed on the output gear shaft, location bearing 11 is installed in fixedly desktop 9 centers, fixedly desktop 9 bottoms are equipped with fixedly desktop pallet 10, after tightening clockwork spring, driven wheel 5 is passed to output gear 12 with clockwork spring moment, output gear shaft drives revolution desktop pallet 8 and rotates, be lined with cushion above the revolution desktop pallet 8, can drive revolution desktop 6 smooth rotation.

Why its revolution can remain a constant speed and have certain adjustable extent, is controlled by speed adjusting gear.Speed adjusting gear is to be made of centrifugal speed limiter 2, speed governing grinding disk 22, speed adjusting lever 1, friction block 23.Speed governing grinding disk 22 is installed on the centrifugal speed limiter 2, friction block 23 is positioned on the speed adjusting lever 1, centrifugal speed limiter 2 is positioned on the worm shaft, when tightening clockwork spring, driven wheel 5 and tooth mill pinlon 19 engagements excessively, third wheel 4 and drive 3 engagements that are installed on the worm-wheel shaft, drive worm gear, Worm screw and worm-gear drive rotates centrifugal speed limiter 2, three heavy bells that support by three reeds on the centrifugal speed limiter 2 produce centrifugal action and grinding disk 22 on it are rubbed with friction block 23 on the speed adjusting lever 1 contact when rotating, size by the friction that produces, the realization rotating speed is adjusted, limiter of speed rotates fast more, the centrifugal force of heavy bell is big more, and friction block 23 frictions on grinding disk 22 and the speed adjusting lever 1 are big more, thereby forces limiter of speed to slow down to remain a constant speed rotation, also controlled simultaneously the velocity of rotation of driven wheel 5, and the rotating speed of output gear 12 also just has been subjected to control, causes the rotation that remains a constant speed of revolution desktop 6, controls the length and the speed of rotation time simultaneously.

When specifically making this utility model, can compare definite velocity of rotation by gear drive according to the use needs of different occasions.

The utility model is simple in structure, safe and reliable, and not electricity consumption, is convenient to penetration and promotion.
