Abstract

The invention discloses a widenable circular rotating dining table which comprises a circular main table surface and an annular table surface, wherein the circular main table surface is arranged on a table rack; the annular table surface can be widened; the annular table surface comprises sector table surfaces in uniform division of circle; the sector table surfaces are mounted below the table rack through a push-pull turning mechanism; the push-pull turning mechanism comprises inserted push-pull shafts and push-pull shaft sleeves; each push-pull shaft is arranged on one side of a corresponding sector table surface; guide pins on the push-pull shafts are arranged in U-shaped variation grooves formed in the push-pull shaft sleeves in a sliding manner; the U-shaped variation grooves consist of long grooves and short grooves which are formed in the outer end parts of the push-pull shaft sleeves and are communicated with each other; central angles of 90 degrees are formed between the long grooves and the short grooves; the positions of the inner ends, in the long grooves, of the guide pins correspond to vertical folding positions of the sector table surfaces; the positions of the inner ends, in the short grooves, of the guide pins correspond to horizontal widening positions of the sector table surfaces; in the horizontal widening positions, support components for bearing force of the sector table surfaces are arranged below the table rack. The area of the widenable circular rotating dining table is not increased when being folded, and the situation that the too much space is occupied by the large unfolded widenable circular rotating dining table can be avoided.

Description

The circular rotating dining table that can widen

Technical field:

The present invention relates to tableware, be specially a kind of circular rotating dining table that can widen.

Background technology:

The circular dining table of prior art, for meeting dining requirement, generally requires the central authorities at circular dining table and arranges rotary dish-plate, cause that circular dining table to be made very big, greatly occupy space, place.

For this, the patent No. is the utility model patent of 93203404.7, it is proposed that a kind of " lazy Susan ", and its technical scheme is: the peripheral dining table part of service plate adopts the desktop plate of decile, desktop plate dig after by the they sup-port laterally produced.

Described " lazy Susan " has problems:

1, component is many, and structure is complicated.

2, complex operation.

3, the hanging of used time desktop socket plate is not below dining table, and obstruction takes a seat, and impact is had dinner.

Summary of the invention:

For the deficiencies in the prior art, the technical problem to be solved is to propose a kind of to operate facility, collect the hidden circular rotating dining table that can widen.

Can solve the problem that the circular rotating dining table that can widen of above-mentioned technical problem, its technical scheme includes the circular top table face being located in table frame and the annular tabletop that can widen top table face, include the fan-shaped desktop of circumference equal dividing the difference is that described annular tabletop, each fan-shaped desktop is installed under the table frame bottom top table face by the push-and-pull switching mechanism being correspondingly arranged, described push-and-pull switching mechanism includes push-pull shaft and the push-and-pull axle sleeve that plug-in mounting connects, described push-and-pull axle sleeve is radially arranged, described push-pull shaft is located at the side of corresponding fan-shaped desktop, guide finger on pull axle is slidably disposed within push-pull shaft and puts in the U-shaped displacement groove offered, described U-shaped displacement groove is the elongated slot and short groove that communicate in position, push-and-pull axle sleeve outer end, the central angle that between described elongated slot and short groove, shape is in 90 ��, guide finger in the inner end positions of elongated slot corresponding to the vertical curling position of fan-shaped desktop, guide finger adds width position in the inner end positions of short groove corresponding to the level of fan-shaped desktop, width position is added in level, described table frame has the support component supporting fan-shaped desktop stress.

For preventing from extracting unintentionally fan-shaped desktop out, the level in fan-shaped desktop adds width position, is provided with locked assembly between adjacent fan-shaped desktop.

Described locked assembly adopts conventional snap close.

Further it is designed as, described top table face is arranged by rotating mechanism, a kind of structure of described rotating mechanism includes rotating axle and rotary axle box, described rotary axle box is located in table frame, described rotation axle is located in bottom top table face and rotates axle together and is rotatably assorted in rotary axle box, in the vertical curling position of fan-shaped desktop, have at least the axle head of a push-pull shaft to enter locking in rotary axle box by opening corresponding on rotary axle box and rotate axle.

Described lock mode is that push-pull shaft axle head snaps in the bayonet socket that on rotation axle, circumference uniform distribution is offered as dop.
