DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order for those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is described in detail clearly and completely below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are merely intended to explain the present disclosure, rather than to limit the present disclosure.

[0026] It is understandable for those skilled in the art that in the description of the present disclosure, terms such as longitudinal, transverse upper, lower, front, rear, left, right vertical, horizontal, top, bottom, inside, and outside indicate the orientation or position relationships based on the drawings. They are merely intended to facilitate and simplify the description of the present disclosure, rather than to indicate or imply that the mentioned system or components must have a specific orientation or must be constructed and operated in a specific orientation. Therefore, these terms should not be construed as a limitation to the present disclosure.

[0027] The present disclosure provides a high-stability support frame that can be used for a folding table, a folding chair, a folding bed, or a footrest. The high-stability support frame is made of stainless steel or aluminum alloy, and is provided with support legs that are telescopic and adjustable to meet different height requirements. Telescopic adjustment is a commonly used and mature technology in the art, and will not be repeated here.

Embodiment 1

[0028] As shown in FIGS. 1 to 3, a high-stability support frame includes two primary connecting rods and two secondary connecting rods. The two primary connecting rods include first primary connecting rod 1 and second primary connecting rod 2. The first primary connecting rod 1 and the second primary connecting rod 2 are intersected. The two secondary connecting rods include first secondary connecting rod 3 and second secondary connecting rod 4. The first secondary connecting rod 3 and the second secondary connecting rod 4 are arranged in parallel. The first secondary connecting rod 3 is connected to a first end of the first primary connecting rod 1 and a first end of the second primary connecting rod 2. The second secondary connecting rod 4 is connected to a second end of the first primary connecting rod 1 and a second end of the second primary connecting rod 2. There are a total of four support legs 5 for supporting the support frame, with each support leg 5 provided at a connection between the primary connecting rod and the secondary connecting rod. Each two support legs 5 are splayed.

[0029] Further, the first primary connecting rod 1 and the second primary connecting rod 2 have equal lengths, and the first secondary connecting rod 3 and the second secondary connecting rod 4 have equal lengths. A triangle formed by the first secondary connecting rod 3 and the two primary connecting rods is the same in shape and area as a triangle formed by the second secondary connecting rod 4 and the two primary connecting rods. The four support legs 5 are evenly stressed, further enhancing the stability of the support frame. A rivet is provided at an intersection of the first primary connecting rod 1 and the second primary connecting rod 2, and the first primary connecting rod 1 and the second primary connecting rod 2 are connected by the rivet. The rivet connection is reliable and cost-effective.

[0030] In an embodiment of the present disclosure, there are a total of four connectors 6, with each connector 6 provided at a connection between the primary connecting rod and the secondary connecting rod. The connector 6 is provided with sockets, and the primary connecting rod, the secondary connecting rod, and the support leg 5 are provided in the sockets.

[0031] Specifically, the primary connecting rod and the connector 6 are connected by a rivet, and the secondary connecting rod and the connector 6 are connected by a rivet. By the rivet connections, the primary connecting rod and the secondary connecting rod are fixed in the sockets to avoid the stability of the support frame from being affected by the rotation of the primary connecting rod or the secondary connecting rod in the socket when the support frame is under force.

[0032] Further, the support frame includes support rods 7. The support rods 7 are respectively provided on the connectors 6. The support rods 7 are matched with the connectors 6 in quantity.

[0033] Specifically, the secondary connecting rods are elliptical tubes, polygonal tubes, or irregular tubes.

[0034] In an embodiment of the present disclosure, the support rods 7 include two first support rods 7 and two second support rods 7. The first support rod 7 and the second support rod 7 have equal lengths. In this case, as shown in FIG. 5, the support frame can be used for a folding table, or a footrest. As shown in FIG. 4, multiple support frames can further be combined together for the folding bed.

Embodiment 2

[0035] In this embodiment, the support rods 7 include two first support rods 7 and two second support rods 7, and a length of the first support rod 7 is greater than a length of the second support rod 7. The support legs 5 include two front support legs 5 and two rear support legs 5. The rear support leg 5 is connected to the first support rod 7, and the front support leg 5 is connected to the second support rod 7. In this case, the support frame can be used for a folding chair or a footrest.

[0036] Other technical features of this embodiment are the same as those of Embodiment 1, and will not be detailed here again.

[0037] The present disclosure is described in detail above. Specific cases are used herein to illustrate the principle and implementation of the present disclosure, and the description of the above embodiments is only intended to help understand the core idea of the present disclosure. It should be noted that several improvements and modifications may also be made by those of ordinary skill in the art without departing from the principles of the present disclosure, which also fall within the protection scope of the claims of the present disclosure.
