An elastic member 63 is also disposed between the operating member 62 and the first sliding seat 2 to provide an elastic force that keeps the operating member 62 locked in the locking grooves 611. By providing multiple locking grooves 611, the position of the first sliding seat 2 relative to the upright body 11 can be adjusted, thereby adjusting the degree of unfolding of the upper end of the first support rod 3.

[0059] The lower support assembly includes a second sliding seat 7, multiple second support rods 8, and multiple second mating rods 9.

[0060] The second sliding seat 7 is slidably disposed on the upright body 11.

In the horizontal direction, the second fixing portion 131 is located between two adjacent second sliding portions 71.

[0061] The lower end of each second support rod 8 is rotatably connected to a corresponding second sliding part 71. Specifically, the lower end of each second support rod 8 can be rotatably connected to a corresponding second sliding part 71 via a rotating shaft 10.

When the folding table is carrying heavy items, the second sliding seat limiting part 72 can provide support, further enhancing the reliability of the folding table frame.

[0065] In one embodiment, the upper support assembly and the lower support assembly are symmetrically arranged relative to the horizontal centerline axis of the upright 1. Therefore, the upper and lower support assemblies can be used interchangeably; that is, when the folding table frame is inverted, the upper support assembly is located below and can be used to support the surface, while the lower support assembly is located above and can be used to support the tabletop 5. This enriches the usage scenarios, avoids accidental operation, and makes the folding table frame of this invention more convenient to use.

[0066] The following explains the working principle of the folding table frame of this utility model:

[0067] like Figures 1-5As shown, the folding table frame is in the unfolded state. The first support rod 3 extends upward from the inside out, and the first mating rod 4 extends downward from the inside out. The first support rod 3 unfolds relative to the upright rod 1, and the first mating rod 4 unfolds relative to the upright rod. The upper ends of the multiple first support rods 3 are higher than the upper ends of the upright rod 1, and the upper ends of the multiple first support rods 3 are located on the same horizontal plane, which facilitates the placement of the tabletop 5 and prevents the tabletop 5 from tilting. The first fixed seat limiting part 16 abuts against the first mating rod 4, and the first sliding seat limiting part 16 abuts against the first support rod 3. The second support rod 8 extends downward from the inside out, and the second mating rod 9 extends upward from the inside out. The second support rod 8 unfolds relative to the upright rod 1, and the second mating rod 9 unfolds relative to the upright rod 1. The lower ends of the multiple second support rods 8 are lower than the lower ends of the upright rod 1, and the lower ends of the multiple second support rods 8 are located on the same horizontal plane, which facilitates the placement of the folding table frame and prevents it from tilting. The second fixed seat limiting part 17 abuts against the second mating rod 9, and the second sliding seat limiting part 72 abuts against the second support rod 8.

[0068] like Figures 7-10 As shown, when in the folded state, the first support rod 3 is close to the upright rod 1, the first cooperating rod 4 is close to the upright rod 1, the upper ends of the multiple first support rods 3 are located on the same horizontal plane, and the upper ends of the multiple first support rods 3 are higher than the upper ends of the upright rod 1. In other embodiments, to further limit the folding volume of the folding table frame, it can also be set that in the folded state, the upper ends of the multiple first support rods 3 are lower than the upper ends of the upright rod 1, the second support rods 3 are close to the upright rod 1, the second cooperating rod 4 is close to the upright rod 1, the lower ends of the multiple second support rods 8 are located on the same horizontal plane, and the lower ends of the multiple second support rods 8 are lower than the lower ends of the upright rod 1. In other embodiments, to further limit the folding volume of the folding table frame, it can also be set that in the folded state, the lower ends of the multiple second support rods 8 are higher than the upper ends of the upright rod 1, such as... Figures 7-8 As shown, the first sliding seat 2 and the second sliding seat 7 are positioned very close together to minimize the folding height of the folding table frame. Since the first fixing part 121 is located between two adjacent first sliding parts 21 in the horizontal direction, the first mating rod 4 is located between two adjacent first support rods 3 in the horizontal direction. Because the first side 14 of each first fixing part 121 is approximately half the length of its second side 15, the first fixing seat 12, while satisfying the rotatable connection with the first mating rod 4, can also reserve a certain amount of space for the first support rod 3. The entire first fixing seat 12 is compactly designed. Similarly, the entire first sliding seat 2, second fixing seat 13, and second sliding seat 7 all adopt a similar design, further ensuring the compact folding volume of the folding table frame.

[0069] When transitioning from the unfolded state to the folded state, the user presses the operating element 62, which disengages from the locking slot 611. At this time, the locking device is unlocked, and the first sliding seat 2 slides from top to bottom relative to the upright 1, causing the first support rod 3 to slide from top to bottom relative to the upright 1 and retract. The second sliding seat 2 slides from bottom to top relative to the upright, causing the second support rod 8 to slide from bottom to top relative to the upright 1 and retract.

[0070] In the description of this utility model, the directions such as "front," "back," "left," "right," "up," "down," "inner," and "outer" are defined with reference to the direction observed by the user when using the folding table, i.e. Figure 3 As shown in the figure, the left direction is "left", the right direction is "right", the upper direction is "up", the lower direction is "down", the direction perpendicular to the viewpoint is "front" and "back", the direction closer to the upright is "inner", and the direction farther from the upright is "outer". These definitions of direction are merely for ease of description and simplification of the present invention, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In the description of the present invention, "rotational connection" refers to a pivot connection.

[0071] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
