Abstract

The utility model relates to an automatic revolving top of dining table. The automatic revolving top is provided with a box-shaped casing composed of an upper cap and a lower cap, and a double-ballistic ball-bearing with inner gear ring is arranged between two caps to form a whole body after locked by a central shaft. A retarding mechanism composed of a motor and a plurality of gearwheels is arranged in the lower cap, which directly rotates the revolving top. The revolving top with simple structure can be used independently, and can reduce nearly half of the power consumption compared with prior art. Meanwhile, the utility model adopts the complete encapsulating structure, which is very convenient to move, store and use, and can be matched with tables to use.

Description

Automatic revolving top of dining table

The utility model relates to the have dinner rotating disk of usefulness of a kind of confession.

The electric turn table that has earlier all based on existing dining table, is promptly opened a hole in the middle of the desktop of ordinary table, motor and reducing gear directly are installed in the hole, drives the facet disc spins on the dining table.The major defect of this frame mode is that the desktop of dining table is destroyed, can't remake general dining table and use, and has so just lost its practicality.For addressing this problem, the money of Jiangsu Province's Yangzhou is tamed and dociled greatly and has been proposed a kind of patent application of electric-hand driven two-purpose Lazy Susan (patent No. 90214685.8) November 1 nineteen ninety, this rotating disk can use separately, its major advantage is to damage the desktop of dining table, can be supporting with various dining tables easily, adaptability is good.But the reducing gear that adopts group of motors and worm gear, worm screw to form from this rotating disk of structure drives rotating disk, and the processing request of miniature worm gear, worm screw is higher relatively on the one hand, can improve cost of manufacture; Owing to adopt two motor-driven, power consumption and cost have been increased on the other hand.In addition, this rotating disk adopts circular ring type base, bottom blow-by, dustproof weak effect, and latch-up-free device between base and upper cover plate, the two trajectory ball bearing are not integral, it is discrete that dislocation easily takes place when moving and deposit, and directly influenced convenience and the practicality used.

The purpose of this utility model is that a kind of improved automatic dining table rotating disk will be provided, and it can reduce power consumption and cost effectively, improves sealing effectiveness, and uses, moves, deposits all very convenient.

The utility model has a rotatable cassette shell, and it is made up of loam cake and lower cover, is provided with two trajectory ball bearings between two lids, and is locked into as a whole by a central shaft; Be provided with by single motor and some the reducing gears that pitch wheel is formed in the described lower cover, its final stage gear is meshed with ring gear.During use the little deck plate of dining table directly placed cassette shell on cover, work as motor rotation, reducing gear drives two trajectory ball bearing rotations, rely on the loam cake of the frictional force drives cassette shell that the trajectory ball rotates on two trajectory ball bearings, also rotate thereupon thereby be placed on the little deck plate of the dining table that covers.Simultaneously, because being frictionally, the rotation of cassette shell loam cake drives, so rotating disk still can be manual arbitrarily when electric operation, to realize electronic and manual two kinds of functions.

The utility model makes structure simpler owing to adopt single motor directly to drive some gear drive rotating disks, has reduced cost and power consumption, has improved its economy.Simultaneously, make complete machine become as a whole owing to adopted the cassette shell and the center shaft type latch-up structure of total incapsulation, exquisite attractive in appearance, good dustproof effect, also improved greatly the convenience moving, deposit, use and practicality,

Concrete structure of the present utility model is provided by the following drawings and embodiment.

Fig. 1 is the front view (partial cutaway) of automatic dining table rotating disk.

Fig. 2 is the vertical view of automatic dining table rotating disk when taking down loam cake.

Do further specifying of embodiment below in conjunction with accompanying drawing: this rotating disk comprises that a cassette shell of being made up of loam cake (3) and lower cover (11) is (for guaranteeing to have higher-strength, housing preferably adopts metal material to make), two trajectory ball bearings of band ring gear (16) are set between two lids, the last trajectory (1) of bearing and ring gear (16) trajectory (15) down interfix, ball (2) in the trajectory is inconsistent with loam cake and lower cover respectively up and down, and can produce certain frictional force, for guarantee that ball can evenly distribute and not slippage trajectory in trajectory, preferably dispose ball locating ring (14) on two trajectories, its thickness should be less than the diameter of ball.Central shaft (10) is arranged on the center of lower cover (11), and it cooperates a bolt that upper and lower covers is locked, but must guarantee that loam cake (3) can the freedom and flexibility rotation.Reducing gear (9) is made up of motor (8) and pitch wheel (4), (5), (6), (7), and installs in a housing, directly is fixed in the lower cover, and final stage gear (4) is meshed with ring gear (16).Also be provided with battery case (12) in the lower cover, for the dry cell of placing the motor power supply.Motor is controlled by power switch (13), and for easy to use, power switch can pick out with lead-in wire.

Claims

1, a kind of confession automatic dining table rotating disk of usefulness of having dinner, this rotating disk has a rotatable cassette shell, it is characterized in that cassette shell is made up of loam cake (3) and lower cover (11), be provided with two trajectory ball bearings of band ring gear (16) between two lids, and lock by central shaft (10) and to become an integral body; Be provided with by single motor (8) and some the reducing gears (9) that pitch wheel is formed in the lower cover, its final stage gear (4) is meshed with ring gear (16).
