[0056] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0059] As attached Figure 1 To the attached Figure 17 As shown, an embodiment of the present invention provides a folding table, including a table frame 20 and a desktop panel 10. The desktop panel 10 is detachably connected to the table frame 20, that is, the desktop panel 10 and the table frame 20 can be folded and stored separately, and the desktop panel 10 can be used alone, with more application scenarios. The table frame 20 includes a table frame 30 and support legs 40. The table frame 30 is used to install the desktop panel 10, and the support legs 40 are used to support it on the ground. The table frame includes a plurality of frames, and the adjacent frames are rotatably connected and have an expanded state and a folded state. When the table frame is folded, the frames are parallel to each other; the support legs 40 of this embodiment can be folded together with the table frame 30, specifically, the support legs 40 include a first branch 41 and a second branch 42, the lower ends of the first branch 41 and the second branch 42 are rotatably connected, the upper end of the first branch 41 is hinged to one frame 31 of the table frame 30, and the second branch 42 is hinged to the other adjacent frame 31, and the rotation axis of the two frames 31 is coaxial with the rotation axis of the lower ends of the first branch 41 and the second branch 42, so that the support legs 40 follow the frame 31 to expand or fold. When the support legs 40 are expanded, the first branch 41 and the second branch 42 form a triangular structure with the table frame 30. The table frame 30 is a frame structure, and the desktop board 10 is embedded in the table frame 30. When the table frame 30 is not folded, the support legs 40 will not be folded, and the triangular support structure makes the table frame 20 more stable, thereby preventing the folding table from being accidentally folded or folded; when the table frame 20 needs to be folded When the desktop board 10 is taken out from the desktop frame 30, the folding part of the folding frame 50 is pushed to transform it from the first state to the second state. The process is as shown in the attached figure. Figure 3 and attached Figure 4As shown, since the rotation axes of the two frames are coaxial with the rotation axes of the lower ends of the first branch 41 and the second branch 42, the folding frame 50 rotates relative to the adjacent straight rod frame 60, and at the same time, the first branch 41 rotates and retracts synchronously relative to the second branch 42 until the folding frame 50 is completely folded. At this time, the first branch 41 and the second branch 42 are parallel and can be rotated and folded relative to the table frame 30 at the same time, as shown in the attached figure. Figure 5 As shown, the entire table frame 20 is folded into a long strip shape, which occupies a small area and is easy to hold.

[0060] The folding table of the present embodiment forms a supporting structure by itself through the foldable table frame and the supporting legs, and does not require an additional connecting rod structure. Compared with the structure that uses cross rods to fold in the prior art, it has fewer pipes and a simpler structure. The table frame is a frame structure, and the table top 10 is embedded in the table frame. When the table frame is not folded, the supporting legs will not be folded, and the triangular supporting structure makes the table frame more stable, thereby preventing the folding table from being accidentally folded and folded, and the structure is more stable. Moreover, since the folded frame frames are parallel to each other, the first branch and the second branch of the supporting legs are also parallel to each other. After the supporting legs are folded toward the frame, the supporting legs are equivalent to the locking structure of the table frame. If the supporting legs are not unfolded first, the table frame cannot be unfolded. When taking the folded and stored table frame, even if only one of the frame frames is held, the table frame will not be unfolded, which is more convenient for users to hold and store. Moreover, the shape of the folded table frame is close to a long strip, which is convenient for storage.

[0061] As attached Figure 1 To the attached Figure 17 In the embodiments of the present invention, the structure of the legs and the connection structure with the table frame are substantially the same, and the legs 40 can rotate and fold together with the table frame 30. Figure 13 and attached Figure 17 As shown, the lower end of the first branch 41 is provided with a first hinge member 43, and the lower end of the second branch 42 is provided with a second hinge member 44. The first hinge member 43 includes a first hinge end 431, which is provided with a first circular hole 432. The second hinge member 44 includes a second hinge end 441, which is provided with a second circular hole 442. The first hinge end 431 and the second hinge end 441 are stacked, and the first circular hole 432 is aligned with the second circular hole 442. The first branch 41 and the second branch 42 rotate about the center of the first circular hole 432 and the second circular hole 442. The center of the first circular hole 432 and the second circular hole 442 are coaxial with the rotation axis of the corresponding two frames 31. The first hinge end 431 and the second hinge end 441 can be rotatably connected together by a bolt.

[0062] Preferably, the second hinge end 441 is located below the first hinge end 431, and the bottom of the first hinge end 431 has a groove 433, which is adapted to the second hinge end 441, so that the bottom surfaces of the first hinge 43 and the second hinge 44 are flush, so that the bottom surface of the support leg 40 is flat, and the folding table can be placed more stably on the ground.

[0063] Since the first branch 41 and the second branch 42 are distributed in a triangular shape with the table frame 30, the first branch 41 and the second branch 42 have a certain inclination angle relative to the table frame 30. In order to facilitate the fixing of the first hinge 43 and the second hinge 44, the first hinge 43 includes a first fixed end 434 for fixedly connected to the first branch 41, the first fixed end 434 and the first hinge end 431 are distributed in an L shape, and the inclination direction of the first fixed end 434 relative to the first hinge end 431 is the same as the inclination direction of the first branch 41 relative to the table frame 30 when it is unfolded; the second hinge 44 includes a second fixed end 443 for fixedly connected to the second branch 42, the second fixed end 443 and the second hinge end 441 are distributed in an L shape, and the inclination direction of the second fixed end 443 relative to the second hinge end 441 is the same as the inclination direction of the second branch 42 relative to the table frame 30 when it is unfolded. Correspondingly, the first fixing end 434 and the second fixing end 443 are each provided with at least two fixing holes, which are fixedly connected to the first branch 41 and the second branch 42 respectively by screws or bolts.

[0064] The upper ends of the first branch 41 and the second branch 42 are respectively rotatably connected to a frame 31. Specifically, the upper ends of the first branch 41 and the second branch 42 are each provided with a fixing part 45, and the fixing part 45 includes a first division 451 and a second division 452. The first division 451 is hinged to the frame 31, that is, the first division 451 is provided with a rotation hole corresponding to the rotation hole on the side of the frame 31, and then hinged by a bolt or a rotating shaft; the second division 452 is fixedly connected to the first branch 41 or the second branch 42. In order to improve the connection stability of the fixing part and the first branch 41 or the second branch 42, the second division 452 is provided with at least two fixing holes, and the upper ends of the first branch 41 and the second branch 42 respectively have at least two corresponding holes to prevent the second division 452 from shaking relative to the first division 41 or the second branch 42.

[0065] To improve the stability when the legs are extended, Figure 12 As shown, the angle A between the first subsection 451 and the second subsection 452 is consistent with the angle B between the first branch 41 or the second branch 42 and the table frame when the first branch 41 or the second branch 42 is extended. In this embodiment, the specific degree of the inclination angle is set according to the size of the table frame 20, ensuring that the rotation axis of the two side frames 31 is coaxial with the rotation axis of the lower ends of the first branch 41 and the second branch 42, so that the support leg 40 can follow the side frame 31 when it is extended or retracted.

[0066] Preferably, as shown in the attached Figure 13 and attached Figure 14 As shown, the upper end surfaces of the first and second branches 41, 42 are inclined. When the first and second branches 41, 42 are unfolded, the upper end surfaces abut against the bottom surface of the frame 31, stably supporting the legs 40 and further stabilizing the triangular structure of the legs 40 and the frame 30. It should be noted that the aforementioned inclined surfaces refer to the upper end surfaces of the first and second branches 41, 42 being inclined relative to the first and second branches themselves. When the table frame is unfolded, the inclined surfaces are horizontal or nearly horizontal relative to the ground.

[0067] The table frame in the table stand has various shapes after being unfolded, such as triangle, quadrilateral, pentagon, hexagon, etc. The following will briefly describe table frames of different shapes in different embodiments.

[0068] Example 1

[0069] As attached Figure 1 To the attached Figure 5 As shown, the table frame 30 in this embodiment includes four frames 31, and the adjacent frames 31 are connected by rotation to form a frame structure when unfolded to support the four sides of the desktop board 10. The folding method of the table frame 30 is that the frames 31 include an even number of folding frames 50, and the folding frames 50 are arranged relatively to each other and have a first state parallel to each other and a second state folded inwards and close to each other; as shown in the attached Figure 4 As shown, in the frame of this embodiment, there are two folding frames 50, which are arranged along the width direction of the table frame 30. The length of the folding frame 50 is less than the length of the straight rod frame 60, so that the two folding frames 50 can be accommodated between the two straight rod frames 60 after being folded in half. Of course, in other embodiments, the four frames 31 can also be folding frames 50, so that the table frame 30 can be folded along the length direction or the width direction when folded, and the table frame 30 is square.

[0070] The frame 31 and the adjacent frame 31 are rotatably connected by a rotating connecting member group 70. The rotating connecting member group 70 has a variety of different structures or sizes. Specifically, in this embodiment, the adjacent frames are connected by a first rotating group 71. The rotation axis of the first rotating group 71 is coaxial with the rotation axis of the corresponding support leg. Since the frames of this embodiment rotate relatively inward when folded, the rotation axis of the first rotating group is located on the inner side of the table frame, and the rotation axes of the first branch and the second branch are also located on the inner side of the table frame. For the convenience of description, the vertical distance between the rotation axes of the first branch and the second branch and the corresponding frames in the horizontal plane is set to L1.

[0071] As attached Figure 2 and attached Figure 17As shown, the first rotating group 71 includes a first connecting member 711 and a second connecting member 714 that are rotatably connected. The first connecting member 711 is fixedly connected to one frame, and the second connecting member 714 is fixedly connected to another adjacent frame. The first connecting member 711 and the frame can be fixed by plugging, welding, or bonding, and the second connecting member 714 can be fixed by plugging, welding, or bonding. Preferably, the frame can be a hollow structure, and the first connecting member 711 and the second connecting member 714 are respectively plugged and fixed to the corresponding frame, which not only facilitates installation but also reduces the weight of the table frame 20, making it easier to carry.

[0072] As attached Figure 17 As shown, the first connecting member 711 includes a first rotating portion, which includes a plurality of first rotating shaft portions 712 spaced apart from each other in an upper and lower direction and a first rotating shaft hole 713 provided on the first rotating shaft portion 712; the second connecting member 714 includes a second rotating portion, which includes a plurality of second rotating shaft portions 715 spaced apart from each other in an upper and lower direction and a second rotating shaft hole 716 provided on the second rotating shaft portion 715. Figure 2 As shown, the first rotation shaft portion 712 and the second rotation shaft portion 715 are engaged with each other, and the first rotation shaft hole 713 and the second rotation shaft hole 716 are concentrically arranged, so that the first connecting member 711 and the second connecting member 714 are rotatably connected.

[0073] As attached Figure 2 , Attachment Figure 3 As shown, the table frame 30 of this embodiment includes two folding frames 50, and the specific structure of the folding frames 50 is described below. The folding frames 50 include two short tubes 51 and a folding connector 52. The folding connector 52 includes a seventh connector 521 and an eighth connector 524 that are rotatably connected. The seventh connector 521 is fixedly connected to one short tube 51, and the eighth connector 524 is fixedly connected to the other short tube 51.

[0074] The seventh connecting member 521 includes a seventh rotating portion, which includes a plurality of seventh rotating shaft portions 522 spaced apart from each other and a seventh rotating shaft hole 523 provided on the seventh rotating shaft portion 522; the eighth connecting member 524 includes an eighth rotating portion, which includes a plurality of eighth rotating shaft portions 525 spaced apart from each other and an eighth rotating shaft hole 526 provided on the eighth rotating shaft portion 525. The seventh rotating shaft portion 522 and the eighth rotating shaft portion 525 are engaged with each other, and the gap between the two short tubes 51 of the folding frame 50 is smaller and smoother, and the gap on the table frame 30 after unfolding is smaller; as shown in the attached figure, Figure 2 As shown, the seventh rotation axis hole 523 and the eighth rotation axis hole 526 are concentrically arranged, so that the seventh connecting member 521 and the eighth connecting member 524 are rotatably connected.

[0075] Preferably, the seventh connecting member 521 also includes a limit member, which is located on the side of the seventh rotating shaft portion 522 and is used to abut against the outer periphery of the eighth rotating shaft portion 525; limiting the rotation angle of the two short tubes 51, and the seventh rotating shaft hole 523 and the eighth rotating shaft hole 526 are located on the outside of the short tube 51, so that the two short tubes 51 can only be folded inward to improve the stability of the table frame 30 in the expanded state.

[0076] The seventh connector 521 can be fixed to the short tube 51 by plugging, welding, or bonding, and the eighth connector 524 can be fixed to another short tube 51 by plugging, welding, or bonding. Preferably, the short tube 51 can be a hollow structure, and the seventh connector 521 and the eighth connector 524 can be respectively plugged and fixed to the corresponding short tube 51. This not only facilitates installation, but also reduces the weight of the table frame 20, making it easier to carry.

[0077] As attached Figure 1 and attached Figure 2 As shown, the upper end surface of the frame 31 has a step 32. When the desk frame 30 is unfolded, the step 32 forms a mounting groove. The mounting groove is a frame-shaped structure, and the desktop panel 10 is inserted into the mounting groove, thereby limiting the four sides of the desktop panel 10 and ensuring the stable installation of the desktop panel 10. The desktop panel 10 can be slightly higher than the mounting groove to facilitate the user to remove the desktop panel 10 from the mounting groove.

[0078] In other embodiments not shown, the upper end surface of the rotating connection point between the frames has a boss, that is, the upper end surface of the rotating connection member group 70 has a boss. When the table frame 30 is unfolded, the boss is located at various horizontal positions of the desktop panel 10 and can abut against the edge of the desktop panel 10, thereby limiting the movement of the desktop panel 10 and improving the stability of the desktop panel 10 in the table frame 30.

[0079] The desktop panel 10 is a foldable structure, including several mutually connected split panels 11. The split panels 11 can be folded forward and backward like a folding fan, or can be composed of several split split panels 11 connected by elastic ropes and then folded. There are various folding methods for the desktop panel 10, all of which are existing technologies and are not listed here one by one.

[0080] Example 2

[0081] As attached Figure 6 and attached Figure 7As shown, the difference between this embodiment and the first embodiment is that the number of frames constituting the table frame 30 is three, one of which is a folding frame 50, and the other two are straight rod frames 60. The specific structure of the folding frame 50 is as described in the first embodiment and will not be repeated here. The frame in this embodiment is rotatably connected to the adjacent frames through a rotating connection group 70. The rotating connection group 70 includes a first rotating group 71 and a second rotating group 72. The rotation axes of the first rotating group 71 and the second rotating group 72 are respectively coaxial with the rotation axes of the corresponding support legs 40. The rotation axes of the first rotating group 71 and the second rotating group 72 are located on the inner side of the table frame 30, and the rotation radius of the second rotating group 72 is larger than that of the first rotating group 71. The rotation radius refers to the straight-line distance from the rotation axis of the second rotating group 72 to the connection point of the second rotating group 72 and the frame, as shown in the attached figure. Figure 6 As shown, the first rotating group 71 connects the straight rod frame 60 and the folding frame 50, the second rotating group 72 connects the two straight rod frames 60, and the folding frame 50 is arranged opposite to the second rotating group 72. As the rotation radius of the second rotating group 72 is larger, as shown in the attached figure, Figure 7 As shown, when the table frame 30 is folded, the folding frame 50 is folded, and the two straight rod frames 60 are parallel to each other, so that the supporting legs 40 can be rotated and folded relative to the table frame 30, further reducing the folded volume of the table frame 20.

[0082] At the same time, since the rotation axis of the frame needs to be coaxial with the rotation axis of the first branch 41 and the second branch 42, the rotation axis of the support leg 40 corresponding to the first rotation group, the first branch 41 and the second branch 42 are located on the inner side of the table frame 30, and the vertical distance from the corresponding frame in the horizontal plane is L1; the rotation axis of the support leg 40 corresponding to the second rotation group 72, the first branch 41 and the second branch 42 are located on the inner side of the table frame 30, and the vertical distance from the corresponding frame in the horizontal plane is L2, L2 is greater than L1, and L2 corresponds to the rotation radius of the second rotation group 72.

[0083] As attached Figure 6 As shown, the first rotating group 71 of this embodiment includes a first connecting member 711 and a second connecting member 714 that are rotatably connected. The first connecting member 711 is fixedly connected to a frame, and the second connecting member 714 is fixedly connected to another adjacent frame. The first connecting member 711 includes a first rotating portion, which includes a plurality of first rotating shaft portions 712 spaced apart from each other and a first rotating shaft hole 713 provided on the first rotating shaft portion 712; the second connecting member 714 includes a second rotating portion, which includes a plurality of second rotating shaft portions 715 spaced apart from each other and a second rotating shaft hole 716 provided on the second rotating shaft portion 715. The first rotating shaft portion 712 and the second rotating shaft portion 715 are engaged with each other, and the first rotating shaft hole 713 and the second rotating shaft hole 716 are concentrically arranged, so that the first connecting member 711 is rotatably connected to the second connecting member 714.

[0084] The second rotating group 72 includes a third connecting member 721 and a fourth connecting member 724 that are rotatably connected. The third connecting member 721 is fixedly connected to one frame, and the fourth connecting member 724 is fixedly connected to another adjacent frame. The third connecting member 721 includes a third rotating portion, which includes a plurality of third rotating shaft portions 722 arranged at intervals up and down and a third rotating shaft hole 723 provided on the third rotating shaft portion 722; the fourth connecting member 724 includes a fourth rotating portion, which includes a plurality of fourth rotating shaft portions 725 arranged at intervals up and down and a fourth rotating shaft hole 726 provided on the fourth rotating shaft portion 725. The third rotating shaft portion 722 and the fourth rotating shaft portion 725 are embedded with each other, and the third rotating shaft hole 723 and the fourth rotating shaft hole 726 are concentrically arranged, so that the third connecting member 721 is rotatably connected with the fourth connecting member 724.

[0085] As attached Figure 7 As shown, in order to allow the space between the two straight rod frames 60 after folding to accommodate the folding frame 50 in the folded state, the length of the third rotation axis portion 722 and the fourth rotation axis portion 725 is greater than the length of the first rotation axis portion 712 and the second rotation axis portion 715, and greater than the width of the frame; correspondingly, the length of the first hinge end 431 of the first hinge 43 corresponds to the length of the third rotation axis portion 722, and the length of the second hinge end 441 of the second hinge 44 corresponds to the length of the fourth rotation axis portion 725.

[0086] Example 3

[0087] As attached Figure 8 and attached Figure 9 As shown, the difference between this embodiment and the first embodiment is that the number of frames constituting the table frame 30 is five, one of which is a folding frame 50, and the other four are straight rod frames 60. The specific structure of the folding frame 50 is as described in the first embodiment and will not be repeated here. The frames in this embodiment are rotatably connected to the adjacent frames through a rotating connection group 70. The rotating connection group 70 includes a first rotating group 71, a second rotating group 72 and a third rotating group 73. The rotation axes of the first rotating group 71, the second rotating group 72 and the third rotating group 73 are respectively coaxial with the rotation axes of the corresponding support legs 40. The rotation axes of the first rotating group 71 and the second rotating group 72 are located on the inner side of the table frame 30, and the rotation radius of the second rotating group 72 is larger than that of the first rotating group 71. The rotation axis of the third rotating group 73 is located on the outer side of the table frame 30, and the rotation direction is opposite to that of the first rotating group 71 and the second rotating group 72.

[0088] In this embodiment, the number of the first rotation group 71 is 2, the number of the second rotation group 72 is 2, and the number of the third rotation group 73 is 1. For the convenience of description, the straight rod frame 60 is distinguished, as shown in the attached figure. Figure 8As shown, the straight rod frames 60 located on both sides of the folding frame 50 are respectively the first straight rod frame 61 and the second straight rod frame 62, and the straight rod frames 60 opposite to the folding frame 50 are respectively the third straight rod frame 63 and the fourth straight rod frame 64. The folding frame 50 is rotationally connected to the first straight rod frame 61 through the first rotating group 71, and is rotationally connected to the second straight rod frame 62 through the second rotating group 72; the other side of the first straight rod frame 61 is rotationally connected to the third straight rod frame 63 through the second rotating group 72, the other side of the second straight rod frame 62 is rotationally connected to the fourth straight rod frame 64 through the first rotating group 71, and the third straight rod frame 63 and the fourth straight rod frame 64 are rotationally connected through the third rotating group 73.

[0089] The first rotating group 71 and the second rotating group 72 in this embodiment are as described in the second embodiment, and their corresponding relationship with the support leg 40 is also as described in the second embodiment. Figure 9 As shown, in order to ensure that the space between the two straight rod frames 60 after folding can accommodate the folding frame 50 in the folded state, the lengths of the third rotation axis portion 722 and the fourth rotation axis portion 725 are greater than the lengths of the first rotation axis portion 712 and the second rotation axis portion 715, and are greater than the width of the frame. The third rotation group 73 includes a fifth connecting member 731 and a sixth connecting member 734. The fifth connecting member 731 is fixedly connected to one frame, and the sixth connecting member is fixedly connected to another adjacent frame. The fifth connecting member 731 includes a fifth rotating portion, which includes a plurality of fifth rotation axis portions 732 arranged at intervals in the upper and lower directions and a fifth rotation axis hole 733 provided on the outer side of the fifth rotation axis portion 732; the sixth connecting member 734 includes a sixth rotating portion, which includes a plurality of sixth rotation axis portions 735 arranged at intervals in the upper and lower directions and a sixth rotation axis hole 736 provided on the outer side of the sixth rotation axis portion 735, as shown in the attached figure. Figure 8 As shown, the fifth rotation axis portion 732 and the sixth rotation axis portion 735 are interlocked, and the fifth rotation axis hole 733 and the sixth rotation axis hole 736 are concentrically arranged, so that the fifth connecting member 731 is rotatably connected to the sixth connecting member 734. Because the rotation axis of the frame needs to be coaxial with the rotation axis of the first branch 41 and the second branch 42, the rotation axis of the first branch 41 and the second branch 42 of the support leg 40 corresponding to the third rotation group 73 is located outside the table frame 30, the first hinge member 43 and the second hinge member 44 extend outward, and the first and second circular holes are aligned and concentric with the fifth and sixth rotation axis holes.

[0090] Since the rotation direction of the third rotating group 73 is opposite to that of the first rotating group 71 and the second rotating group 72, during the folding process, the third straight rod frame 63 is first rotated toward the first straight rod frame 61, so that the second rotating group 72 connected to the first straight rod frame 61 is opened. At the same time, the third rotating group 73 connecting the third straight rod frame 63 and the fourth straight rod frame 64 is rotated outward, so that the third straight rod frame 63 and the fourth straight rod frame 64 are rotated inward, and then the folding frame 50 is rotated inward and folded into the third straight rod frame 63. and the first straight rod frame 61. At the same time, the second rotating group 72 connecting the fourth straight rod frame 64 and the second straight rod frame 62 is opened, and the first rotating group 71 connecting the second straight rod frame 62 and the fourth straight rod frame 64 is rotated inward, folding the third straight rod frame 63 and the fourth straight rod frame 64 between the folding frame 50 and the second straight rod frame 62, and then pushing the second straight rod frame 62 toward the first straight rod frame 61, so that the folding frame moves closer to the first straight rod frame 61 until the frames are parallel to each other. Thus, the folded table frame 30 is as shown in the attached figure. Figure 9 As shown, the folding frame 50 is folded and located between the parallel first straight rod frame 61 and the third straight rod frame 63, and the third straight rod frame 63 and the fourth straight rod frame 64 are folded in the opposite direction and located between the parallel folding frame 50 and the second straight rod frame 62. The table frame 30 is in the shape of a long strip as a whole, and the frames are parallel to each other. Then, the folded legs 40 are rotated and retracted relative to the table frame 30 to complete the folding of the entire table frame 20.

[0091] Example 4

[0092] As attached Figure 10 and attached Figure 11 As shown, the difference between this embodiment and the third embodiment is that the number of frames constituting the table frame 30 is 6, and all frames are straight rod frames 60, and all straight rod frames 60 are opposite to each other, while the frames in this embodiment are rotatably connected to adjacent frames through a rotating connection group 70, and the rotating connection group 70 includes a first rotating group 71, a second rotating group 72 and a third rotating group 73. The rotation axes of the first rotating group 71, the second rotating group 72 and the third rotating group 73 are respectively coaxial with the rotation axes of the corresponding support legs 40, the rotation axes of the first rotating group 71 and the second rotating group 72 are located on the inner side of the table frame 30, and the rotation radius of the second rotating group 72 is larger than that of the first rotating group 71, and the rotation axis of the third rotating group 73 is located on the outer side of the table frame 30, and the rotation direction is opposite to that of the first rotating group 71 and the second rotating group 72.

[0093] In this embodiment, the number of the first rotation group 71 is 2, the number of the second rotation group 72 is 2, and the number of the third rotation group 73 is 2, and they are arranged opposite to each other. Figure 10As shown, the straight rod frame 60 of this embodiment includes two oppositely arranged fifth straight rod frames 65, two oppositely arranged sixth straight rod frames 66, and two oppositely arranged seventh straight rod frames 67. One side of the fifth straight rod frame 65 is rotationally connected to one side of the sixth straight rod frame 66 through a first rotation group 71, the other side of the fifth straight rod frame 65 is rotationally connected to the seventh straight rod frame 67 through a second rotation group 72, and the other side of the sixth straight rod frame 66 is rotationally connected to another seventh straight rod frame 67 through a third rotation group 73, thereby forming a closed-loop table frame 30 structure.

[0094] The rotation direction of the third rotating group 73 is opposite to that of the first rotating group 71 and the second rotating group 72. During the folding process, the sixth straight rod frame 66 is first rotated toward the fifth straight rod frame 65, so that the third rotating group 73 connected to the sixth straight rod frame 66 is rotated and opened, and the table frame 30 gradually turns into a parallelogram and then the internal space gradually shrinks until the sixth straight rod frame 66 and the fifth straight rod frame 65 are close together and fit together, and the two seventh straight rod frames 67 are close together and fit together, and then the two seventh straight rod frames 67 are folded toward each other. The sixth straight rod frame 66 is brought together, so that after the table frame 30 is folded, the fifth straight rod frame 65 and the sixth straight rod frame 66 are folded inward relative to each other, and the sixth straight rod frame 66 and the seventh straight rod frame 67 are folded outward relative to each other, so that the sixth straight rod frame 66 and the seventh straight rod frame 67 are located between the fifth straight rod frame 65 and the other seventh straight rod frame 67. The table frame 30 is in the shape of a long strip as a whole, and the various frames are parallel to each other. Then the folded legs 40 are rotated and retracted relative to the table frame 30 to complete the folding of the entire table frame 20.

[0095] The first rotation group 71 , the second rotation group 72 , and the third rotation group 73 in this embodiment are as described in the third embodiment, and their corresponding relationship with the supporting foot 40 is also as described in the third embodiment.

[0096] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
