Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 5, an embodiment of the present invention provides an expandable dining table, which includes a square bracket 1, four table legs 2 for supporting the square bracket 1, a first table top 3 and two second table tops 4, wherein two opposite side edges of the square bracket 1 are respectively provided with a through pipe 5, two slide bars 6 which are vertically folded are arranged in the through pipe 5, one end of each slide bar 6 is provided with a stopper 7, the stoppers on the two folded slide bars 6 are respectively located at two ends of the through pipe 5, the stopper 7 is provided with a fixing column 8 for fixing the second table top, a mounting plate 9 is fixed in the middle of the square bracket 1, the mounting plate 9 is vertically and upwardly provided with a mounting column 10, the mounting column 10 is rotatably provided with a linkage rod 11, the outer end of the linkage rod 11 is respectively rotatably provided with a connecting rod 12, one end of the connecting rod 12 is rotatably arranged on the second table top 4, the top of the mounting column 10 is fixed with a disc 13, the outer edge of the disc 13 is vertically and upwardly provided with two annular rings 14, the annular rings 14 are arranged at intervals, the two annular rings 14 are concentric rings, the bottom of the first tabletop 1 is provided with two guide columns 15, the positions, close to the two ends, of the linkage rod 11 are respectively provided with a guide sleeve 16, the guide columns 15 are arranged in the guide sleeves 16 in a sliding mode, the bottom of the first tabletop 1 is also provided with two guide sliding columns 17, the two guide sliding columns 17 are respectively correspondingly abutted against the two annular rings 14, the two annular rings 14 are respectively provided with a notch 18, a connecting line of the two notches 18 penetrates through the axis of the mounting column 10, and the connecting rod 12 is provided with a bending part 121 so that the connecting rod 12 does not interfere with the annular rings 14.

The outer contour of the first table top 3 is a runway shape, that is, the outer contour of the first table top comprises two arcs arranged oppositely and a long edge connecting the two arcs. The outer contour shape of the second table top 4 comprises two arcs which are parallel and arranged at intervals and a short edge which is connected with the two arcs, and the arc contour of the first table top 3 is the same as that of the second table top 4.

A motor (not shown) is arranged below the square support 1 and is used for driving the linkage rod 11 to rotate. A battery (not shown) is also included, which supplies power to the motor.

The two connecting rods 12 are respectively connected with the respective second table tops through a connecting part 19, the connecting rods 12 are rotatably connected with the connecting part 19, the connecting part 19 is fixedly connected with the second table top 4, and the connection of the two connecting parts 19 penetrates through the axis of the mounting column 10.

When the two second table tops are in an initial state, the two second table tops are located below the first table top to form a stacked state, when the table tops need to be expanded, the motor is started, the motor drives the linkage rod to rotate for 180 degrees, the sliding guide columns fall into the openings of the annular rings, the first table top is lowered to the height same as that of the second table tops, the connecting rod drives the second table tops to move outwards in the process of rotating for 180 degrees, the second table tops move to the maximum position and then are drawn close inwards for a distance, and finally the second table tops are clamped on two sides of the first table top, and the first table top and the two second table tops form a complete expanded table top. When the initial state needs to be recovered, the motor is started, and the motor drives the linkage rod to rotate 180 degrees reversely.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
