[0033] Reference below Figures 1 to 5 A multifunctional folding table according to an embodiment of the utility model is described.
[0034] refer to Figures 1 to 5 As shown, the multifunctional folding table according to an embodiment of the utility model includes a storage frame 100 , a first table top 200 and a support portion 300 .
[0035] The storage frame 100 may include two vertical poles arranged side by side, the vertical poles may extend vertically, and a cross bar may be provided between the top ends of the two vertical poles and between the bottom ends of the two vertical poles. A first storage cavity 101 and a second storage cavity 102 are formed in the storage frame 100.
[0036] The first table top 200 is rotatably connected to the storage frame 100, and the rotation axis of the first table top 200 can extend laterally and be parallel to the cross bar of the storage frame 100. The first table top 200 can be rotated to a horizontal unfolded state. In this state, the first table top 200 can be used to place tableware or for office work. The first table top 200 can be rotated to a storage state stored in the first storage cavity 101. In this state, the first table top 200 is located in the storage frame 100, and the first table top 200 and the storage frame 100 are approximately in the same vertical plane and do not protrude from the storage frame 100.
[0037] The support part 300 is rotatably connected to the storage frame 100. The support part 300 can be a plate-like structure. The plate surface of the support part 300 can be a vertical surface. The rotation axis of the support part 300 can extend vertically. The support part 300 can be rotated to an expanded state to support the first table board 200 in a horizontal state. That is, when the first table board 200 is rotated to a horizontal state, the support part 300 can be rotated to the bottom of the first table board 200 and abut against the bottom surface of the first table board 200, thereby supporting the first table board 200 so that the first table board 200 can be stably maintained in a horizontal state. The support part 300 can be rotated to a storage state stored in the second storage cavity 102. In this state, the support part 300 is located in the storage frame 100, and the support part 300 and the storage frame 100 are roughly in the same vertical plane and do not protrude from the storage frame 100, so that the multifunctional folding table can be folded as a whole to form a vertical plate-like structure when not in use, so that it can be attached to the wall to reduce the space occupied.

After use, the first table board 200 and the support part 300 can be rotated so that the first table board 200 is stored in the first storage cavity 101 of the storage frame 100, and the support part 300 is stored in the second storage cavity 102 of the storage frame 100, so that the multifunctional folding table can be in a folded state, thereby reducing the space occupied. In addition, the multifunctional folding table of the utility model has a simple structure, is easy to manufacture, and has a low cost. In addition, the multifunctional folding table is easy to operate when folding or unfolding, saving time and effort.
[0039] It should be noted that, in addition to extending vertically, the vertical rod of the storage frame 100 may also be slightly inclined relative to the vertical direction.

The rotation axis of the first table top 200 may also be slightly inclined relative to the horizontal direction, and it only needs to be able to rotate to a horizontal state or be stored in the first storage cavity 101. The rotation axis of the support portion 300 may also be slightly inclined relative to the vertical direction, and it only needs to be able to rotate to be supported on the first table top 200 or be stored in the second storage cavity 102. In addition to being set as a plate-like structure, the support portion 300 may also be other suitable structures, which will not be repeated here.

For example, the first axis 103 may be located in the middle of the height direction of the storage frame 100, the first axis 103 extends in the left-right direction, the two ends of the first axis 103 may be connected to two vertical poles respectively, the second axis 104 may be located in the middle of the left-right direction of the storage frame 100 and extend vertically, the top end of the second axis 104 may be connected to the first axis 103, and the bottom end of the second axis 104 may be connected to the horizontal rod.
[0041] In this way, the first table top 200 can be accurately rotated around the horizontal axis to a horizontal state or stored in the first storage cavity 101. At the same time, the support part 300 can be accurately rotated around the vertical axis to support the first table top 200 in a horizontal state or stored in the second storage cavity 102, and the unfolding and storage effects are better.
[0042] In some embodiments of the present invention, Figures 1 to 3 As shown, the first storage cavity 101 is located above the second storage cavity 102, the storage frame 100 forms a third storage cavity 105 on one side of the second storage cavity 102, the multifunctional folding table further comprises a second table top 400, the second table top 400 is rotatably connected to the first shaft 103, the second table top 400 can be rotated to a horizontal state or stored in the third storage cavity 105, and the support portion 300 can be rotated to support the second table top 400 in a horizontal state. For example, the area of the second storage cavity 102 and the area of the third storage cavity 105 can be approximately equal, the area of the first storage cavity 101 can be approximately equal to twice the area of the second storage cavity 102, the first table top 200 can be approximately semicircular, and the second table top 400 can be approximately quarter-circular.
[0043] In this embodiment, in addition to the first table board 200, a second table board 400 is also provided. The first table board 200 can be used as a dining table. When dining is required, the first table board 200 is rotated downward to a horizontal state, and the support portion 300 is rotated to support the first table board 200. After dining is completed, the first table board 200 is rotated upward to be stored in the first storage cavity 101. The second table board 400 can be used for temporary office work. When office work is required, the second table board 400 is rotated upward to a horizontal state, and the support portion 300 is rotated to support the second table board 400. After office work is completed, the second table board 400 is rotated downward to be stored in the third storage cavity 105. This makes the multifunctional folding table of the utility model more versatile and more practical.
[0044] It should be noted that, in addition to being semicircular, the first table top 200 and the second table top 400 may be in other shapes, such as rectangular or square, in addition to being quarter-circular, and details will not be repeated here.

The first table top 200 and the second table top 400 are rotatably connected to the first shaft 103 through corresponding connection components 500, and the support part 300 is rotatably connected to the second shaft 104 through corresponding connection components 500, so that the rotation of the first table top 200, the second table top 400 and the support part 300 is more convenient and smooth.
[0047] In some embodiments of the present invention, Figures 1 to 3As shown, the connecting assembly 500 on the first shaft 103 can be slidably adjusted along the axial direction of the first shaft 103. With this arrangement, the positions of the first table board 200 and the second table board 400 can be finely adjusted along the axial direction of the first shaft 103, which is not only more convenient to use, but also more convenient for the support part 300 to support the first table board 200 or the second table board 400, and has better practicality.
[0048] In some embodiments of the present invention, Figures 1 to 3 As shown, the first table top 200 and the second table top 400 are connected to different connection components 500 respectively, and along the axial direction of the first shaft 103, the connection components 500 connected to the first table top 200 and the connection components 500 connected to the second table top 400 are arranged alternately. In this way, not only can the first table top 200 and the second table top 400 be rotated separately according to needs, but also when the positions of the first table top 200 and the second table top 400 are finely adjusted along the axial direction of the first shaft 103, the interference between the connection components 500 connected to the first table top 200 and the connection components 500 connected to the second table top 400 can be reduced, and the adjustment is more convenient.
[0049] In some embodiments of the present invention, Figures 1 to 3 As shown, the connecting component 500 includes a sleeve portion 501, a connecting seat 504 and a fastener 508. The sleeve portion 501 is provided with a sleeve and is sleeved on the outside of the first axis 103 or the second axis 104 through the sleeve. The sleeve portion 501 is provided with two first connecting portions 502 at intervals. The first connecting portion 502 is provided with a first connecting hole 503. The two first connecting holes 503 are coaxially arranged. The connecting seat 504 is used to connect the first table top 200, the second table top 400 or the supporting portion 300. The connecting seat 504 is provided with a second connecting portion 505. The second connecting portion 505 is provided with a second connecting hole 506. The connecting seat 504 is formed with mounting grooves 507 on the outside of both ends of the second connecting hole 506. The two first connecting portions 502 are respectively installed in the two mounting grooves 507, and the first connecting hole 503 is coaxial with the second connecting hole 506. The fastener 508 is inserted into the first connecting hole 503 and the second connecting hole 506.
[0050] In this embodiment, the connecting seat 504 can be provided with a connecting plate 509, and at least two third connecting holes 510 can be provided on the connecting plate 509. The third connecting holes 510 are used to install bolts between the first table top 200, the second table top 400 or the supporting part 300, so as to connect the connecting seat 504 to the first table top 200, the second table top 400 or the supporting part 300. When the first table board 200, the second table board 400 or the support part 300 needs to be installed, the sleeve part 501 is sleeved on the outside of the first axis 103 or the second axis 104, and then the two first connecting parts 502 of the sleeve part 501 are respectively installed in the two installation grooves 507 of the connecting seat 504, and the first connecting hole 503 is coaxial with the second connecting hole 506, and finally the fastener 508 is inserted. When the first table board 200, the second table board 400 or the support part 300 needs to be disassembled, the corresponding fastener 508 is pulled out, and then the connecting seat 504 is separated from the sleeve part 501. The connecting assembly 500 of this embodiment has a simple structure and high structural strength, and the first table board 200, the second table board 400 or the support part 300 is easy to install and disassemble.
[0051] It should be noted that the connection component 500 may also be other suitable structures. For example, it may also be directly set as a sleeve, and the sleeve is sleeved outside the first axis 103 or the second axis 104. The first table top 200, the second table top 400 or the support part 300 is directly welded to the sleeve.

When the first table top 200 is rotated to be stored in the first storage cavity 101, the first table top 200 is approximately In a vertical state, the second limiting portion 108 is then rotated, and the first limiting portion 107 and the second limiting portion 108 can be located on both sides of the thickness direction of the first table top 200, thereby cooperating to limit the free rotation of the first table top 200, so that the first table top 200 remains in a storage state stored in the first storage cavity 101. When the first table top 200 needs to be used, the second limiting portion 108 can be rotated away from one side of the thickness direction of the first table top 200. The structure is simple, the operation is convenient, and the limiting effect on the first table top 200 is better.
[0054] It should be noted that, in addition to rotation, the second limiting portion 108 may also be movable in other ways, for example, it may be slidably connected to the storage frame 100 .

When the support portion 300 is stored in the second storage cavity 102, the caster 301 is stored in the storage groove 109. The caster 301 can be supported on the ground. The caster 301 can make the support portion 300 rotate more smoothly. The storage groove 109 is provided. When the support portion 300 is stored in the second storage cavity 102, the caster 301 is stored in the storage groove 109, so that not only the folding and folding effect of the multifunctional folding table is better, but also the caster 301 can be prevented from being exposed to the outside and damaged.
[0056] It should be noted that when the support part 300 rotates to support the first table top 200 or the second table top 400, a locking structure such as a locking pin can be set between the support part 300 and the first table top 200, or between the support part 300 and the second table top 400. In addition, a temporary connection structure can also be set between the support part 300 and the first table top 200, or between the support part 300 and the second table top 400 for detachable connection to prevent the support part 300 from rotating at will.
