Description

A kind of dining table, exhibition booth and small-sized stage are with changeing core

Technical field

The utility model relates to a kind of commentaries on classics core, particularly dining table, exhibition booth and small-sized stage with changeing core.

Background technology

Rotatable dining table, exhibition booth and small-sized stage all are to be realized rotating by the commentaries on classics core that the middle part is provided with, dining table, exhibition booth and small-sized stage are divided into following two kinds with the commentaries on classics core at present: a kind of for mechanical, it need realize rotation by manually-operated, because changeing core, mechanical type needs manually-operated, though it is cheap, but owing to only have some small-sized dining tables also have to use at the bottom of its automaticity, exhibition booth and small-sized stage have not adopted this kind commentaries on classics core, and mechanical type changes core and is eliminated gradually; Also having a kind of is electronic commentaries on classics core, and this kind changes the complex structure of core, the price height, and installation and difficult in maintenance needs the professional to install, and therefore makes universal being restricted of electronic commentaries on classics core of present existing structure.

The utility model content

In order to solve the problems of the technologies described above, the utility model provides a kind of dining table, exhibition booth and small-sized stage with changeing core, and purpose is simplified structure, reduces cost, conveniently installs and safeguard.

Be achieved in that for reaching above-mentioned purpose the utility model a kind of dining table, exhibition booth and small-sized stage are with changeing core, it comprises base, loam cake and ball, affixed motor in the base wherein, the output shaft of motor is connected with motor gear, motor gear and gear wheel engagement, the gear ring of gear wheel is connected with ball, and ball is connected with loam cake.

Described ball is two-layer, be placed in above the gear ring and below, be provided with respectively the raceway that is connected with base with loam cake below the top and lower floor ball of upper strata ball, raceway and loam cake coupling part are fixed in and cover.

Be provided with limiting plate between the inboard of described raceway and base coupling part and the motor.

Described loam cake is to be made of loam cake enclosing cover and loam cake inner cap, and the loam cake enclosing cover is fixedlyed connected with the loam cake inner cap.

Described base periphery upper surface is provided with interior side shield, and the enclosing cover periphery lower surface of loam cake is provided with outer side shield, and inboard baffle position is higher than outer side shield, and interior side shield has overlapping with outer side shield, and is gapped between interior side shield and the outer side shield.

Described motor is for exchanging the non-directional motor.

Advantage of the present utility model and effect are as follows:

The utility model is owing to adopt said structure, and it has simplified the structure of automatic commentaries on classics core, and is with low cost, and does not need the professional can realize installing and safeguarding, puts as long as aim at the center of circle on the table.The utility model promptly can adopt powered version to rotate automatically, do not having can also to adopt manual rotation under the situation of power supply simultaneously, so the utility model is beneficial to universal.
