[0041] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0042] This application provides a folding bracket and a folding table, aiming to solve the problems of low overall integrity, inconvenience, and poor stability of existing folding tables. This folding bracket, through optimized structural design, achieves a tight fit between the tabletop, legs, and support components, improving the overall stability and ease of use of the folding table. A detailed description will follow.

[0043] Please refer to Figures 1 to 3. The folding bracket includes: a rotating joint 1, a leg tube assembly 2, a movable component, a linkage tube 4, and a support tube 5. The leg tube assembly 2 includes a front leg tube 20 and a rear leg tube 21, which are rotatably connected. The movable component is movably connected to either the front leg tube 20 or the rear leg tube 21. The movable component is movably connected to the rotating joint 1. The linkage tube 4 is movably connected to either the front leg tube 20 or the rear leg tube 21. The support tube 5 is movably connected to both the linkage tube 4 and the rotating joint 1.

[0044] The folding bracket of this application embodiment uses a rotating joint 1, a movable part and a linkage tube 4 to connect the foot tube assembly 2 and the support tube 5 into a whole in a linkage manner. It does not require splicing during use, has good integrity, fast response speed, and can be quickly unfolded or folded. Moreover, due to the good integrity of the structure, the stability of the entire folding bracket is very good during use.

[0045] The folding bracket includes a left support tube assembly and a right support tube assembly. The left support tube assembly and the right support tube assembly each have two support tubes 5. The two ends of the support tubes 5 are rotatably connected to the rotating joint 1 and the corresponding linkage tube 4, respectively.

[0046] Among them, the rotating joint 1 is a hinged seat. The ends of the two support tubes 5 of the left support tube group or the right support tube group are respectively hinged to the two ends of the rotating joint 1 on the corresponding side. When the folding bracket is fully unfolded, the two support tubes 5 are on the same straight line.

[0047] The left and right support tube groups correspond to two linkage tubes 4 respectively. The two linkage tubes 4 on the same side have the same length. One end of the two linkage tubes 4 is close to each other and rotates to connect. The other ends of the two linkage tubes 4 are far apart to form a V-shaped arrangement. The far ends of the two linkage tubes 4 are rotated to connect to the support tubes 5 on the corresponding sides respectively.

[0048] Optionally, the ends of the two linkage tubes 4 that are close to each other can be rotatably connected to the rotating connecting seat 7. The rotating connecting seat 7 allows the two linkage tubes 4 to rotate more smoothly, reduces friction and jamming, and improves the operability of the folding bracket; the rotating connecting seat 7 can be a hinged seat.

[0049] Furthermore, the middle sections of the two connecting pipes 4 on the same side are rotatably connected to the front foot pipe 20 and the rear foot pipe 21. Specifically, one connecting pipe 4 is rotatably connected to the front foot pipe 20 via a first hinge shaft 40, and the other connecting pipe 4 is rotatably connected to the rear foot pipe 21 via a second hinge shaft 41. The first hinge shaft 40 passes through the front foot pipe 20 and the connecting pipe 4, rotatably fixing the corresponding connecting pipe 4 to the front foot pipe 20, and the second hinge shaft 41 passes through the rear foot pipe 21 and the other connecting pipe 4, rotatably fixing the corresponding connecting pipe 4 to the rear foot pipe 21.

[0050] One function of the movable component in this embodiment is to facilitate the movement of the rotating joint 1 relative to the leg tube assembly 2, thereby enabling the folding or unfolding of the folding bracket. Therefore, the movable component can be one of various structural components, such as a slider, a flipping linkage, or a telescopic rod 3. Here, the telescopic rod 3 is used as an example for explanation, and other forms of movable components will not be described in detail. In this embodiment, the movable component is the telescopic rod 3. Part of the telescopic rod 3 is housed inside the front leg tube 20, and the telescopic rod 3 can move within the front leg tube 20. Of course, part of the telescopic rod 3 can also be housed inside the rear leg tube 21, and the housed part can move within the rear leg tube 21. The upper end of the telescopic rod 3 is exposed, and the exposed end is connected to the rotating joint 1. When the rotating joint 1 is moved by an external force, it can drive the telescopic rod 3 to move, thereby causing the two support tubes 5 to unfold or fold.

[0051] It is worth mentioning that the first hinge shaft 40 does not affect the movement of the telescopic rod 3 within the front leg tube 20. For example, the first hinge shaft 40 is located on the side of the telescopic rod 3, and there is no connection between the first hinge shaft 40 and the telescopic rod 3. Furthermore, the lower half of the telescopic rod 3 has a first through groove, which is opened along the axial direction of the telescopic rod 3. A portion of the first hinge shaft 40 is accommodated in the first through groove and can slide along it.

[0052] The folding bracket also includes a folding drive that can drive the telescopic rod 3 to move within the front leg tube 20.

[0053] In this embodiment, the folding drive is a scissor lift assembly 6, which includes at least one scissor lift unit.

[0054] The scissor lift unit includes a first scissor lift tube 60 and a second scissor lift tube 61. The middle parts of the first scissor lift tube 60 and the second scissor lift tube 61 are rotatably connected by a pin. The two ends of the first scissor lift tube 60 and the second scissor lift tube 61 are respectively connected to a rotary joint 1 and two rotary connecting seats 7. Optionally, the scissor lift tube assembly 6 may also include two or more scissor lift units.

[0055] When the first scissor lift tube 60 and the second scissor lift tube 61 rotate vertically relative to each other, the entire support begins to fold. The upper ends of the first scissor lift tube 60 and the second scissor lift tube 61 respectively drive their respective connected rotating joints 1 to move upward, while simultaneously pushing their respective connected rotating connecting seats 7 downward. The upward movement of the rotating joints 1 causes the telescopic rod 3 to extend from the front leg tube 20, and at the same time, the two support tubes 5, which unfold into a straight line, rotate around the rotating joints 1 and the linkage tube 4, realizing the folding and parallel arrangement of the two linkage tubes 4. The downward movement of the rotating connecting seat 7 folds the front leg tube 20 and the rear leg tube 21 together through the linkage tube 4. As the first scissor lift tube 60 and the second scissor lift tube 61 move closer to each other, they bring the front leg tubes 20 and the rear leg tubes 21 on both sides together, realizing the bundled folding of the entire folding support. When the first scissor lift tube 60 and the second scissor lift tube 61 rotate horizontally, the entire support unfolds from the folded state, and its action is the opposite of the folding action of the support, which will not be described in detail here.

[0056] To improve the user experience of the folding stand, the bottom of both the front leg tube 20 and the rear leg tube 21 are fitted with pads to increase the friction between the stand and the ground and improve the stability of the stand.

[0057] The folding bracket in this embodiment utilizes the linkage tube 4, telescopic rod 3, and scissor tube assembly 6 to form the foot tube assembly 2 and support tube 5 into a whole, thereby improving the overall integrity of the bracket. It is more convenient to unfold or fold during use and has better stability. In addition, it has a compact structure, is easy to fold, occupies little space, is easy to carry and store, and is particularly suitable for outdoor use.

[0058] Referring to Figure 4, an embodiment of this application also provides a folding table, including a tabletop 8 and the aforementioned folding support, wherein the tabletop 8 is connected to the folding support.

[0059] Optionally, the lower side of the tabletop 8 is provided with a slot. The slot is elongated and its cross-sectional shape matches the shape of the support tube 5. The size of the slot is slightly larger than the size of the support tube 5, allowing the support tube 5 to be engaged in the slot, thus achieving a detachable connection between the tabletop 8 and the folding bracket. When needed, first unfold the folding bracket, align the slot of the tabletop 8 with the support tube 5, and press it firmly to connect the tabletop 8 and the folding bracket. When disassembly is required, simply separate the tabletop 8 from the support tube 5.

[0060] The slot design not only facilitates the installation and removal of the tabletop 8, but also enhances the connection stability between the tabletop 8 and the folding bracket, ensuring that the tabletop 8 will not easily shake or fall off during use.

[0061] The folding table provided in this application has a wide range of applications, especially suitable for outdoor activities. Due to its small size and light weight when folded, it is easy to carry and store, making it ideal for outdoor activities such as camping and beach leisure. In addition, the folding table can also be used in indoor settings such as homes and offices. Because of its simple structure and convenient operation, users can unfold or fold it as needed, saving space and increasing flexibility.

[0062] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims. Industrial applicability

[0063] In summary, this application provides a folding bracket and a folding table. This folding bracket can be quickly unfolded or folded with a fast response speed, and has good integrity and stability. The folding table using this folding bracket can make the folding table small in size and light in weight after folding, making it easy to carry and store.
