[0042] The present disclosure will be further described below with reference to the accompanying drawings and embodiments:

[0043] As shown in Figures 1 to 7, a support frame includes a support tube 1, a leg tube 2 and a bracket 3. The two brackets 3 are connected by a cross tube 4. The support tube 1 and the leg tube 2 are detachably arranged at the upper and lower ends of the bracket 3, respectively. The bracket 3 is also provided with a receiving hole 32. After the support tube 1 and the leg tube 2 are disassembled, the support tube 1 and the leg tube 2 are respectively inserted into the receiving hole 32 from both sides, and the support tube 1 and the leg tube 2 are inserted into each other.

[0044] The detachable connection between the support tube 1, the leg tube 2 and the bracket 3 can be a threaded connection, a plug-in connection, etc. This embodiment adopts a plug-in connection structure, and the specific structure is as follows:

[0045] The bracket 3 has two insertion slots A31 on its upper portion, located at two corners of the bracket 3. The two support tubes 1 are inserted into the insertion slots A31, forming an inverted figure eight shape. The bracket 3 has two insertion slots B33 on its lower portion, located at two corners of the bracket 3. The two leg tubes 2 are inserted into the insertion slots B33, forming an inverted figure eight shape.

[0046] It is worth noting that the top surface of the bracket 3 in this embodiment is in the shape of a rectangular parallelepiped, and the two upper corners and the two lower corners can be understood as the corner positions of the rectangular parallelepiped. When the two support tubes 1 are respectively inserted into the two insertion slots A31, the two support tubes 1 and the two insertion slots A31 as a whole present an inverted figure eight shape. When the two leg tubes 2 are respectively inserted into the two insertion slots B33, the two leg tubes 2 and the two insertion slots B33 as a whole present an inverted figure eight shape. Because the two insertion slots A31 are located at the top of the bracket 3 and the two insertion slots B33 are located at the bottom of the bracket 3, the two figure eight shapes formed are opposite.

[0047] Of course, the top surface of the bracket 3 can also be polygonal, circular, elliptical or other shapes, and there is no limitation on the specific shape. In addition, the above-mentioned figure eight shape and inverted figure eight shape can also be understood as shapes close to figure eight or herringbone.

[0048] The insertion slots A31 and B33 are not connected, and the support tube 1 and the leg tube 2 are not in a straight line, so as to avoid the situation in which the support tube 1 and the leg tube 2 cannot form effective support due to mutual insertion during use.

[0049] As shown in Figures 5 and 11, the accommodating hole 32 is a stepped hole, including a large-diameter through hole 321 and a small-diameter through hole 322 that are interconnected. A step surface 323 is formed at the connection between the large-diameter through hole 321 and the small-diameter through hole 322. The large-diameter through hole is located on the side of the horizontal tube 4, and the leg tube 2 is inserted into the large-diameter through hole 321, and the end portion is against the step surface 323; the corresponding support tube 1 is inserted through the small-diameter through hole and inserted into the leg tube 2, reducing the exposed surface of the support tube 1.

[0050] It is worth noting that the inner diameter of the large-aperture through-hole 321 is larger than that of the small-aperture through-hole 322. Furthermore, a stepped surface 323 is formed on the end surface of the large-aperture through-hole 321 near the small-aperture through-hole 322. The extended direction of the stepped surface 323 forms an angle with both the extension direction of the small-aperture through-hole 322 and the extension direction of the large-aperture through-hole 321. The angle can be a right angle, an acute angle, or an obtuse angle. Furthermore, the stepped surface 323 can be either a flat surface or a curved surface.

[0051] Optionally, the support tube 1 can also be inserted into the large-diameter through hole 321, with the end thereof abutting against the step surface 333; the corresponding leg tube 2 is inserted through the small-diameter through hole 322 and into the support tube 1, reducing the exposed surface of the leg tube 2.

[0052] As shown in Figures 12 and 13, a guide wire 4 or an elastic member 5 is connected between the support tube 1 and the leg tube 2, wherein the elastic member 5 can specifically be a connection structure with elastic potential energy such as an elastic rope or a spring. The above structure makes it difficult for the support tube 1 and the leg tube 2 to be connected as a whole and makes it difficult to lose, and the installation of the support tube 1 and the leg tube 2 can be traced. A long strip-shaped notch 34 is provided on the side wall of the plug-in slot A31 and the plug-in slot B33, and the long strip-shaped notch 34 is connected to the receiving hole 32. The guide wire 4 or the elastic member 5 can be set in the plug-in slot A31 and the plug-in slot B33 along the long strip-shaped notch 34 to make the outer surface more regular.

[0053] A blind hole 30 is provided in the middle of the bracket 3. The two ends of the cross tube 4 are respectively inserted into the blind holes 30 of the two brackets 3. The bracket 3 may also be provided with threaded holes, and the cross tube 4 and the bracket 3 are connected by threads. There are two receiving holes 32, located on either side of the cross tube 4, with one receiving hole 32 tilted upward and the other tilted downward. This ensures that the support tubes 1 and leg tubes 2 on the two brackets are tilted upward and downward respectively when stored, avoiding mutual interference and reducing the storage volume.

[0054] Optionally, in this embodiment, the cross tube 4 and the bracket 3 are directly plugged into each other through the receiving hole 32. The specific structure is as follows:

[0055] A support frame includes a support tube 1, a leg tube 2 and a bracket 3. A receiving hole 32 is provided in the middle of the bracket 3. The receiving hole 32 is a stepped hole, including a large-diameter through hole 321 and a small-diameter through hole 322 that are interconnected. A step surface 323 is formed at the connection between the large-diameter through hole 321 and the small-diameter through hole 322. The cross tube 4 is inserted into the large-diameter through hole 321, and the end portion abuts against the step surface 323; the support tube 1 and the leg tube 2 are respectively detachably arranged at the upper and lower ends of the bracket 3, and after the support tube 1 and the leg tube 2 are disassembled, they respectively pass through the small-diameter through hole 322 and are inserted into the cross tube 4.

[0056] The support tube 1 and leg tube 2 can be arranged to be inserted into each other or to fit together. Alternatively, both tubes can be C-shaped tubes that fit together to restrict each other's freedom. The interlocking structure can also be any other structure that fits together to restrict relative freedom.

[0057] At the same time, one of the support tube 1 and the leg tube 2 may be a C-shaped tube. Specifically, the support tube 1 may be a C-shaped tube, or the leg tube 2 may be a C-shaped tube.

[0058] As shown in Figure 8, when the support frame of the present invention is applied to a bed, multiple support frames are required. The multiple support frames are arranged side by side, and the multiple support tubes 1 are the same length, and the multiple leg tubes 2 are the same length. The multiple support tubes on both sides are respectively connected to the two edge tubes of the bed through clamping blocks to form a stable support.

[0059] As shown in FIG9 , when the support frame of the present disclosure is applied to a table, the four leg tubes 2 are of the same length and constitute a support foot frame, and the four support tubes 1 are of the same length and constitute a support top frame. The table top is installed behind the support top frame and placed horizontally.

[0060] As shown in Figure 10, when the support frame of the present invention is applied to a chair, the length of the support tube 1 at the rear of the crossbar is greater than the length of the support tube 1 at the front of the crossbar, and the four support tubes constitute a support top frame. When the soft surface support of the chair is installed on the support top frame, the height difference between the rear support tube and the front support tube is suitable for providing a sitting or lying space.

[0061] The support frame disclosed herein is also suitable for use in a hanging chair. In this case, only one support tube needs to be provided at the upper middle portion of a bracket, and the soft-surface seat pocket can be hung on the two support tubes.

[0062] The various components of the support frame disclosed herein are folded together to form a whole, making the opening and folding of the product easier and more traceable, while also making the volume smaller and more regular after folding.

[0063] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "examples," "specific examples," or "some examples" means that a specific feature, structure, material, or characteristic described in conjunction with that embodiment or example is included in at least one embodiment or example of the present disclosure. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0064] Although the embodiments of the present disclosure have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limiting the present disclosure. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present disclosure without departing from the principles and purpose of the present disclosure. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present disclosure are still within the scope of the technical solution of the present disclosure. Industrial Applicability

[0065] The support frame inserts the support tubes and leg tubes through the bracket from both sides and then inserts them into each other so that the support tubes, leg tubes and bracket form a whole after being folded, making the opening and folding of the product easier and more traceable. At the same time, the insertion of the tubes into each other after folding reduces the exposed surface, making the volume smaller and more regular after folding.
