The two frame arms 21 are hinged on the first table top 1 and the second table top 3 respectively, and the two frame arms 21 are hinged to each other.

The two frame arms 21 are folded so that the first table top 1 and the second table top 3 are close to each other.

The first table top 1 and the second table top 3 are respectively folded in half around the frame arm 21 .

A plate-shaped frame is finally formed by folding and folding, so that the table top can be changed and folded.

The folded frame arm 21 reserves a storage space for storing small-volume items in the plate-shaped frame.

The first tabletop 1 and the second tabletop 3 have the same structure. The first tabletop 1 includes a tabletop 11 and a widening portion 12 fixed at the bottom end of the tabletop 11 away from the edge of the folding frame 2. The first tabletop 1 and the second tabletop When the desktop 3 is folded to the first desktop 1 and the folding frame 2 and the second desktop 3 and the folding frame 2 are close to each other, the setting of the widening portion 12 can increase the storage space between the first desktop 1 and the second desktop 3. At the same time, the integrity of the first desktop 1 and the second desktop 3 after being folded can be better, which is beneficial to the alignment of the openings of the first desktop 1 and the second desktop 3 .

The hinge structure between the frame arm 21 and the first table top 1, the frame arm 21 and the second table top 3, and the frame arm 21 and the frame arm 21 includes a main connecting part 51 and an auxiliary connecting part 52 that are rotatably connected to each other. 51 Removably connected to the side end of the table board 11 on the first table top 1 close to the folding frame 2, one of the frame arms 21 away from the side end of the table board 11 and the other frame arm 21 close to the side end of the second table top 3 , the plurality of auxiliary connecting parts 52 are respectively detachably connected to the side end of one frame arm 21 close to the first table top 11 , the other frame arm 21 away from the side end of the second table top 3 and the table board 11 on the second table top 3 close to At the side end of the frame arm 21, after the external table top or barbecue is removed from the folding frame 2, when the first table top 1 and the second table top 3 are close together, the main connecting part 51 and the auxiliary connecting part 52 between the two frame arms 21 From the original horizontal parallel to the vertical parallel state, at the same time, the main connection part 51 and the auxiliary connection part 52 between the first table top 1 and the folding frame 2 and the second table top 3 and the folding frame 2 are changed from the original horizontal parallel state to vertical. state.

The bottoms of the first desktop 1 and the second desktop 3 are provided with a tripod structure 4 for supporting the first desktop 1 and the second desktop 3, and the tripod structure 4 can be folded to be level with the first desktop 1 or the second desktop 3. Aligned state.

The tripod structure 4 includes two symmetrical support parts arranged on the bottom of the table board 11 , and the support parts include at least two main limit parts 41 and at least two auxiliary limit parts 43 fixed on the bottom of the table board 11 and a rotating connection. A support frame between at least two main limiting portions 41, the support frame is clamped between the primary limiting portion 41 and the secondary limiting portion 43, the middle portion of the primary limiting portion 41 is a convex arc structure, supporting One section of the frame is located in the arc-shaped structure, the end of the secondary limiting portion 43 is an S-shaped structure, and the other section of the support frame is clamped inside the secondary limiting portion 43 of the S-shaped structure.

The support frame includes a main frame body 421 and a sub frame body 422 that are fixedly connected to each other. The main frame body 421 is rotatably connected between the two main limiting parts 41. When the support frame is in a vertical and unfolded state, the sub frame body 422 is locked. Connected to the inner side of the sub-limiting portion 43, when the support frame is in the folded state, the sub-frame body 422 is in contact with the bottom of the table board 11, and one end of the sub-frame body 422 is in an inclined state. When the table is folded, it will be stuck in the sub-limiting position The sub-frame body 422 on the inner side of the portion 43 can be pulled out of the sub-limiting portion 43 to release the position-limiting fixation of the support frame, and the support frame can be folded and stored.

The side end of the table board 11 away from the folding frame body 2 is provided with a handle (not shown), which facilitates carrying the folded and stored table.

A storage space for storing small-volume items is reserved between the first desktop 1 and the second desktop 3 in the folded state. The storage space can store the external desktop removed from the folding frame 2, so that the removed external desktop can be stored. It is shared with the first table top 1 and the second table top 3, and can also store small-sized items used in conjunction with the table. When the table top is not placed in the folding frame 2, but items such as a foldable barbecue can be placed The rear grill is placed in the storage space for common storage.

When in use, the folding frame body 2 can be properly folded according to the needs, so as to adjust the length between the first desktop 1 and the second desktop 3 to a suitable use length, and an external desktop can also be placed on the folding frame body 2 during use. , so as to make the usable area of the table larger, or place a foldable barbecue grill whose bottom is flush with the ground in the inner space of the folding frame body 2 to increase the versatility of the table.

When it is not needed, the folding frame body 2 is folded to the maximum state, that is, the two frame arms 21 are changed from the horizontal state to the vertical contact state, and then the tripod structure 4 is folded to the first table top 1 and the first table top 1 respectively. At the bottom of the two tabletops 3, then fold the first tabletop 1 and the second tabletop 3 around the frame arm 21 to a state parallel to the frame arm 21. At this time, the first tabletop 1, the second tabletop 3 and the folding frame body 2 are formed together. The plate-shaped frame is convenient for carrying and storage of the table.

The outside table top and the folded barbecue can also be placed in the plate-shaped frame, so that the outside table and the barbecue can be carried or stored together with the plate-shaped frame, which reduces the need to carry or store in batches. Trouble.

Through the design of the foldable structure, the variable effect of the table top can be achieved, and the foldable storage effect of the table can also be achieved, the storage volume of the table can be reduced, and the folding operation is simple and fast.

The above is only a preferred embodiment of the present invention; but the protection scope of the present invention is not limited to this; any person skilled in the art is within the technical scope disclosed by the present invention; according to the technical solution of the present invention Equivalent replacement or change with its improved concept; all should be covered within the protection scope of the present invention.
