[0056] In the following text, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature and not restrictive.

[0057] Refer to Figures 1 - 13 , which shows a foldable table leg structure of a preferred embodiment of the present utility model, including:

[0058] A first support frame 1, on the first side 11 in the length direction of the first support frame 1, a first inner wall 131 is provided, and on the second side 12 in the length direction of the first support frame 1, a second inner wall 141 is provided, and the second inner wall 141 is disposed opposite to the first inner wall 131;

[0059] A first connection structure 2, the first connection structure 2 is disposed on the first inner wall 131;

[0060] A second connection structure 3, the second connection structure 3 is disposed on the second inner wall 141;

[0061] A second support frame 4, the second support frame 4 is rotatably connected to the first connection structure 2, the second support frame 4 has a first unfolded state perpendicular or inclined to the first support frame 1 and a first folded state parallel to the first support frame 1, and the second support frame 4 rotates to switch between the first unfolded state and the first folded state; and

[0062] A third support frame 5, the third support frame 5 is rotatably connected to the second connection structure 3, the third support frame 5 has a second unfolded state perpendicular or inclined to the first support frame 1 and a second folded state parallel to the first support frame 1, and the third support frame 5 rotates to switch between the second unfolded state and the second folded state;

[0063] When the third support frame 5 is in the second folded state and the second support frame 4 is in the first folded state, both the third support frame 5 and the second support frame 4 are located on the same side of the first support frame 1.

[0064] In the foldable table leg structure of the present utility model, since the first inner side wall 131 is provided on the first side 11 in the length direction of the first support frame 1, the first connection structure 2 is provided on the first inner side wall 131, and the second support frame 4 is rotatably connected to the first connection structure 2, the second support frame 4 can rotate relative to the first support frame 1. And when the second support frame 4 is switched from the first unfolded state to the first folded state, the second support frame 4 can be rotated to be parallel to the first support frame 1. Similarly, since the second inner side wall 141 is provided on the second side 12 in the length direction of the first support frame 1, the second inner side wall 141 is disposed opposite to the first inner side wall 131, the second connection structure 3 is provided on the second inner side wall 141, and the third support frame 5 is rotatably connected to the second connection structure 3, the third support frame 5 can rotate relative to the first support frame 1. And when the third support frame 5 is switched from the second unfolded state to the second folded state, the third support frame 5 can be rotated to be parallel to the first support frame 1. Among them, when the second support frame 4 is in the first folded state, the third support frame 5 is in the second folded state, and both the second support frame 4 and the third support frame 5 are located on the same side of the first support frame 1, making the second support frame 4 parallel to the first support frame 1 and the third support frame 5 parallel to the first support frame 1 can reduce the thickness of the foldable table leg structure after folding, reduce the overall volume of the foldable table leg structure after folding, so as to be able to reduce the occupied space of the foldable table leg structure after folding and be more convenient for storage.

[0065] See Figure 7 , in an embodiment, when the second support frame 4 is in the first folded state, the projection of the first support frame 1 in the length direction covers the projection of the second support frame 4 in the length direction;

[0066] When the third support frame 5 is in the second folded state, the projection of the first support frame 1 in the length direction covers the projection of the third support frame 5 in the length direction. In this way, making the thickness of the foldable table leg structure after folding equal to the thickness of the first support frame can further reduce the overall thickness of the foldable table leg structure after folding, so as to further reduce the overall volume of the foldable table leg structure after folding, make the foldable table leg structure after folding occupy less space and be convenient for storage.

[0067] In one embodiment, when the second support frame 4 is in the first folded state, the second support frame 4 abuts against the first support frame 1 to play a role in folding positioning, restricting the second support frame 4 from further rotating. At the same time, the second support frame 4 is closely attached to the first support frame 1, which is beneficial to further reducing the overall thickness of the foldable table leg structure after folding;

[0068] When the third support frame 5 is in the second folded state, the third support frame 5 abuts against the first support frame 1 to play a role in folding positioning, restricting the third support frame 5 from further rotating. At the same time, the third support frame 5 is closely attached to the first support frame 1, which is beneficial to further reducing the overall thickness of the foldable table leg structure after folding.

[0069] See Figures 1 - 3 and Figure 9 , in one embodiment, the first support frame 1 includes:

[0070] The first table leg 13 is located on the first side 11 in the length direction of the first support frame 1, and the first table leg 13 is provided with a first inner side wall 131;

[0071] The second table leg 14 is located on the second side 12 in the length direction of the first support frame 1, and the second table leg 14 is provided with a second inner side wall 141; and

[0072] The first cross bar 15 is located between the first inner side wall 131 and the second inner side wall 141, and the first cross bar 15 connects the first inner side wall 131 and the second inner side wall 141, realizing the connection of the first table leg 13 and the second table leg 14, making the first support frame 1 form a frame structure, which is simple and practical, low in cost, and high in structural strength. At the same time, since the first cross bar 15 is located between the first inner side wall 131 and the second inner side wall 141, it will not increase the thickness dimension of the first support frame 1, thus being more beneficial to reducing the overall thickness of the foldable table leg structure after folding.

[0073] In one embodiment, when the second support frame 4 is in the first folded state, the second support frame 4 abuts against the first cross bar 15 to play a role in folding positioning, restricting the second support frame 4 from further rotating. At the same time, the second support frame 4 is closely attached to the first support frame 1, which is beneficial to further reducing the overall thickness of the foldable table leg structure after folding;

[0074] When the third support frame 5 is in the second folded state, the third support frame 5 abuts against the first cross bar 15 to play a role in folding positioning, restricting the third support frame 5 from further rotating. At the same time, the third support frame 5 is closely attached to the first support frame 1, which is beneficial to further reducing the overall thickness of the foldable table leg structure after folding.

[0075] In one embodiment, the number of the first crossbars 15 is three. One of the first crossbars 15 is located between the top of the first inner wall 131 and the top of the second inner wall 141. The three first crossbars 15 are arranged at intervals along the height direction of the first support frame 1, so that the first table legs 13 and the second table legs 14 are more reliably connected together, further enhancing the structural strength of the first support frame 1, thereby improving the support stability of the foldable table leg structure.

[0076] See Figures 3 - 5 , Figures 10 - 13 , in one embodiment, both the second support frame 4 and the third support frame 5 are provided with a first connection portion 423 and a second connection portion 424;

[0077] Both the first connection structure 2 and the second connection structure 3 include:

[0078] A seat body 21, and the seat body 21 is connected to the first inner wall 131 or the second inner wall 141;

[0079] A first connection shaft 22, the first connection shaft 22 is vertically arranged on the seat body 21, and the upper part 221 of the first connection shaft 22 extends above the seat body 21 and passes through the first connection portion 423. The upper part 221 of the first connection shaft 22 is rotatably matched with the first connection portion 423. The lower part 222 of the first connection shaft 22 extends below the seat body 21 and passes through the second connection portion 424. The lower part 222 of the first connection shaft 22 is rotatably matched with the second connection portion 424;

[0080] An upper limit member 23, the upper limit member 23 is connected to the upper part 221 of the first connection shaft 22, and the upper limit member 23 abuts against the first connection portion 423 to limit the first connection portion 423 from disengaging from the upper part 221 of the first connection shaft 22;

[0081] A lower limit member 24, the lower limit member 24 is connected to the lower part 222 of the first connection shaft 22, and the lower limit member 24 abuts against the second connection portion 424 to limit the second connection portion 424 from disengaging from the lower part 222 of the first connection shaft 22. That is, due to the rotatable fit between the upper part 221 of the first connection shaft 22 and the first connection portion 423 and the rotatable fit between the lower part 222 of the first connection shaft 22 and the second connection portion 424, both the second support frame 4 and the third support frame 5 can rotate relative to the first support frame 1. At the same time, since the first connection portion 423 is located above the seat body 21 and the second connection portion 424 is located below the seat body 21, the first connection portion 423 and the second connection portion 424 jointly clamp the seat body 21, which can support the second support frame 4 or the third support frame 5, facilitating improving the connection stability between the second support frame 4 and the first support frame 1, and at the same time, enabling the second support frame 4 to rotate more smoothly and stably. Similarly, it is beneficial to improve the connection stability between the third support frame 5 and the first support frame 1, and at the same time, enabling the third support frame 5 to rotate more smoothly and stably.

[0082] See Figures 10 - 11 , in one embodiment, the seat body 21 includes:

[0083] A third connecting portion 211, which is connected to the first inner side wall 131 or the second inner side wall 141;

[0084] A fourth connecting portion 212, which is connected to the upper end of the third connecting portion 211. The upper portion 221 of the first connecting shaft 22 passes through the fourth connecting portion 212, and the fourth connecting portion 212 is located below the first connecting portion 423;

[0085] A fifth connecting portion 213, which is connected to the lower end of the third connecting portion 211. The lower portion 222 of the first connecting shaft 22 passes through the fifth connecting portion 213, and the fifth connecting portion 213 is located above the second connecting portion 424. This seat body 21 has a simple and practical structure, high structural strength, and can reliably support the first connecting portion 423 and the second connecting portion 424, thereby improving the connection reliability between the second support frame 4 and the first support frame 1 and the connection reliability between the third support frame 5 and the first support frame 1.

[0086] In one embodiment, the number of the first connecting structures 2 is at least two, and at least two first connecting structures 2 are arranged at intervals along the height direction of the first support frame 1 to further improve the connection reliability between the second support frame 4 and the first support frame 1. At the same time, the second support frame 4 can rotate smoothly;

[0087] The number of the second connecting structures 3 is at least two, and at least two second connecting structures 3 are arranged at intervals along the height direction of the first support frame 1 to further improve the connection reliability between the third support frame 5 and the first support frame 1. At the same time, the third support frame 5 can rotate smoothly.

[0088] See Figures 1 - 3 and Figures 12 - 13 , in one embodiment, both the second support frame 4 and the third support frame 5 include:

[0089] A third table leg 41;

[0090] At least two second cross bars 42, the first end 421 in the length direction of the second cross bar 42 is connected to the third table leg 41, and the second end 422 in the length direction of the second cross bar 42 is provided with a first connecting portion 423 and a second connecting portion 424. At least two second cross bars 42 are arranged at intervals along the height direction of the third table leg 41 to form a frame-type second support frame 4 or third support frame 5, which has a simple and practical structure, low cost, and high structural strength, thereby improving the support stability of the foldable table leg structure.

[0091] A preferred embodiment of the present utility model provides a folding table, which includes the above-mentioned foldable table leg structure.

[0092] For the folding table of the present utility model, due to the adoption of the above-mentioned foldable table leg structure, the thickness of the foldable table leg structure after folding can also be reduced, the overall volume of the foldable table leg structure after folding is reduced, so that the occupied space of the foldable table leg structure after folding can be reduced, and it is more convenient for storage.

[0093] See Figures 1 - 3 , the folding table further includes:

[0094] A tabletop 6;

[0095] Two second connecting shafts 7, the second connecting shaft 7 is provided with a first connecting section 71 and a second connecting section 72. The second connecting section 72 extends along the width direction of the first support frame 1, and the second connecting section 72 is connected to the bottom surface of the tabletop 6. The first connecting section 71 extends along the length direction of the first support frame 1. The first connecting section 71 of one of the second connecting shafts 7 passes through the first inner side wall 131 and is rotatably connected to the first table leg 13, and the first connecting section 71 of the other second connecting shaft 7 passes through the second inner side wall 141 and is rotatably connected to the second table leg 14, so that the first support frame 1 can rotate relative to the tabletop 6. The first support frame 1 has a third unfolded state perpendicular to the tabletop 6, and the first support frame 1 also has a third folded state that fits against the bottom surface of the tabletop 6 and is parallel to the tabletop 6. The first support frame 1 rotates and switches between the third unfolded state and the third folded state; wherein, when the second support frame 4 is in the first folded state, the third support frame 5 is in the second folded state, the second support frame 4 and the third support frame 5 are both located on the same side of the first support frame 1, and the first support frame 1 is in the third folded state, making the second support frame 4 parallel to the first support frame 1, making the third support frame 5 parallel to the first support frame 1, and making the first support frame 1 parallel to the tabletop 6 can reduce the thickness of the folded folding table, that is, the thickness of the folded folding table is equal to the sum of the thickness of the tabletop 6 and the thickness of the first support frame 1, reducing the overall volume of the folded folding table, so that the occupied space of the folded folding table can be reduced, and it is more convenient for storage; in addition, when the second support frame 4 is in the first unfolded state, the third support frame 5 is in the second unfolded state, and the first support frame 1 is in the third unfolded state, the first cross bar 15 at the top of the first support frame 1 abuts against the end of the tabletop 6 close to the second connecting shaft 7 to limit the first support frame 1 in the third unfolded state, and the tops of the third table legs in the second support frame 4 and the third table legs in the third support frame 5 abut against the bottom surface of the tabletop 6 to make the tabletop 6 horizontally placed on the foldable table leg structure.

[0096] See Figures 3 - 5 , in an embodiment, the folding table further includes:

[0097] The connecting base 8 is connected to the bottom surface of the table top 6, and the second connecting section 72 is connected to the connecting base 8. In this way, the second connecting section 72 can be connected to the connecting base 8, and then the connecting base 8 is connected to the bottom surface of the table top 6 to achieve the second connecting shaft 7 being fixed to the table top 6. This not only improves the connection stability between the second connecting shaft 7 and the table top 6, but also reduces the installation difficulty of the second connecting shaft 7 and the table top 6, making the installation of the second connecting shaft 7 more convenient.

[0098] See also Figures 3 - 5 In one embodiment, the connecting seat 8 extends along the length direction of the first support frame 1 to further increase the connection stability between the connecting seat 8 and the table top 6, so that the second connecting shaft 7 is more reliably fixed to the table top 6.

[0099] In one embodiment, the folding table further comprises:

[0100] The first fastener 9, the head of the first fastener 9 is against the side of the connecting seat 8 facing away from the bottom surface of the table board 6, the rod of the first fastener 9 passes through the connecting seat 8 and is screwed to the table board 6 to reliably fix the connecting seat 8 on the table board 6. The installation operation of the connecting seat 8 is simple and the connection reliability is high.

[0101] See also Figure 4 and Figure 5 There are multiple first fasteners 9, and the multiple first fasteners 9 are arranged in sequence along the length direction of the connecting seat 8 to further strengthen the connection between the connecting seat 8 and the table top 6.

[0102] In one embodiment, an avoidance area is formed between adjacent first cross bars 15 located at the upper portion of the first support frame 1. When the first support frame 1 is in the third folded state, the first avoidance area can accommodate the portion of the second connecting shaft 7 exposed from the connecting seat 8 and the first support frame 1 as well as the connecting seat 8, so as to play an avoidance role and enable the first support frame 1 to fit with the bottom surface of the table top 6.

[0103] In one embodiment, one of the bottom surface of the table top 6 and the top of the third table leg 41 is provided with a limiting groove 411, and the other is provided with a limiting protrusion 101. When the first support frame 1 is in the third expanded state, the second support frame 4 is in the first expanded state, and the third support frame 5 is in the second expanded state, the limiting protrusion 101 cooperates with the limiting groove 411 to limit the horizontal movement of the table top 6 relative to the foldable table leg structure, so that the folding table is stably maintained.
