Detailed Description

The following describes the structural and operational principles of the present invention in detail with reference to the accompanying drawings: as shown in figures 1-6, the utility model relates to a folding table, which comprises four vertical table legs 1, a supporting plate 2 is fixedly connected with the upper part of the table legs 1 at the same side, the supporting plate 2 is enclosed into a rectangular frame, a mounting frame 3 is arranged at the inner side of the supporting plate 2, a rotating mechanism 4 is fixedly connected with the mounting frame 3 and is positioned near one corner of the frame, the mounting frame 3 comprises two supporting rods 31, two ends of the supporting rods 31 are respectively fixedly connected with the supporting plate 2, a lower tabletop 5 is also fixedly connected with the upper part of the rotating mechanism 4, an upper tabletop 6 is superposed on the lower tabletop 5, the side edges of the upper tabletop 6 and the lower tabletop 5 are connected with a connecting piece 7 which enables the upper tabletop 6 to be folded in an overturning way, the rotating mechanism 4 comprises a lower rotary disc 41, a lower through hole 42 is arranged at the center of the lower rotary disc 41, a circular groove 43 taking the lower through hole 42 as the center is arranged, go up carousel 45 central authorities and be equipped with through-hole 46, go up through-hole 46 and down the coaxial and all establish with axostylus axostyle 47 sliding sleeve of through-hole 42, axostylus axostyle 47 both ends are equipped with spacing arch 48, and spacing arch 48 is injectd ball 44 and is gone up carousel 45 and lower carousel 41 in and make carousel 45 and lower carousel 41 can use axostylus axostyle 47 to rotate relatively as the center.

The upper desktop 6 and the lower desktop 5 of the present embodiment are both rectangular and have the same size and structure; the upper turntable 45 and the lower turntable 41 in the rotating mechanism 4 have the same size and structure.

The connecting pieces 7 are arranged in the length direction of the upper table top 6 and the lower table top 5 and are positioned at the same side. When the lower desktop 5 rotates by 90 degrees by taking the shaft rod 47 as an axis to unfold the upper desktop 6, the upper desktop 6 can be horizontally erected on the supporting plate 2 when being overturned and unfolded by taking the connecting piece 7 as an axis, so that the area of the desktop is enlarged to two times of the original area.

The lower end of the lower tabletop 5 is fixedly provided with a positioning block 8 which is abutted against the inner side of the supporting plate 2 and is used for ensuring that the center of the lower tabletop 5 coincides with the center of a rectangular frame enclosed by the supporting plate 2 and improving the stability of the table. And a limiting plate 9 is fixedly arranged on the supporting plate 2 opposite to the positioning block 8, the limiting plate 9 corresponds to the positioning block 8, and when the positioning block 8 rotates 90 degrees to the opposite direction of the supporting plate 2 by taking the shaft rod 47 as a center, the positioning block 8 abuts against the limiting plate 9.

This embodiment prefers that the axle 47 is located at 1/2 connecting the center of the rectangular frame enclosed by the pallet 2 and one corner thereof. The shaft lever 47 is arranged at the position, so that when the upper desktop 6 is unfolded after the lower desktop 5 rotates by 90 degrees, the upper desktop 6 and the lower desktop 5 can be uniformly erected on the rectangular frame surrounded by the supporting plate 2, and the center of the unfolded desktop is superposed with the center of the rectangular frame; after the upper desktop 6 is unfolded, the situation that instability is caused because the center of the unfolded desktop is not overlapped with the center of the rectangular frame and even the center of the desktop is positioned outside the rectangular frame is avoided.

The specific working process is as follows: as shown in fig. 6, the initial position 10 when the upper desktop and the lower desktop are folded, the positioning block 8 fixed on the lower desktop 5 abuts against the inner side of the supporting plate 2, when the area of the desktop needs to be enlarged, the lower desktop 5 rotates 90 degrees counterclockwise around the shaft rod 47 as the axis, at this time, the positioning block 8 abuts against the limiting plate 9, the lower desktop 5 cannot rotate, the length direction of the lower desktop 5 is perpendicular to the length direction of the rectangular frame surrounded by the supporting plate 2, the upper desktop 6 is folded and erected on the supporting plate 2 by using the connecting piece 7 as the axis, and at this time, the area of the desktop is increased by two times compared with the area of the desktop at the initial position.

When the area of the desktop needs to be reduced, the unfolded desktop area can be doubled only by reversely operating the processes.

Naturally, the present invention can be embodied in many other forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be made by one skilled in the art without departing from the spirit or essential attributes thereof, and it is intended that all such changes and modifications be considered as within the scope of the appended claims.
