[0002] However, in the prior art, although folding furniture such as folding chairs, folding beds, folding tables, folding tents, etc. significantly optimize the space utilization efficiency in design, their diverse folding frame structures have become a pain point that cannot be ignored. The unique folding mechanisms and assembly methods of each piece of furniture not only increase the training cost and time of employees on the production line, but also hinder the standardization and automation processes of the production process. Whenever a new folding furniture product is introduced, employees often need to go through a learning curve to master its unique assembly skills again, which not only reduces production efficiency, but also increases labor costs and management complexity. In addition, the diverse folding structure designs may also complicate the spare parts inventory management, because different folding components are often not interchangeable, increasing the inventory pressure and logistics costs. Therefore, there is an urgent need for a modular and standardized folding frame. Summary of the Utility Model

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0032] Referring to Figures 1 to 5 as shown, a folding frame that can be switched between an unfolded state and a stored state, the folding frame includes a first connecting seat 1 and at least three second connecting seats 2. Among them, the number of the second connecting seats 2 includes but is not limited to three. Preferably, the second connecting seats 2 are arranged around the outside of the first connecting seat 1 at equal intervals, so that the force on the folding frame is more balanced.
[0033] The first connecting seat 1 and the second connecting seat 2 are connected by a first connecting rod 3, and the second connecting seat 2 is provided with at least one second connecting rod 4; one end of the second connecting rod 4 is connected to the second connecting seat 2, and the other end of the second connecting rod 4 is a free end for connecting a folding furniture.
[0034] The first connecting seat 1 has a first end face 11, and the second connecting seat 2 has a second end face 21; referring to Figure 1 and Figure 2 as shown, when the folding frame is in the unfolded state and the first end face 11 is facing downwards, the second end face 21 is lower than or flush with the first end face 11, and the free end of the second connecting rod 4 extends upwards. Among them, the first end face 11 and the second end face 21 can be a flat surface or an arc surface.
[0035] When the folding furniture using the folding frame is a folding chair (such as a folding sunshade chair, a folding recliner, a folding swing chair, a folding hanging basket, etc.), a folding bed (such as a folding hammock) or a folding table, the corners of a plate member (such as a wooden board, a plastic board, an iron board, etc.) or a fabric (such as canvas, etc.) can be connected to the second connecting rod 4 or the third connecting rod 5. Referring to Figure 1 and Figure 2 as shown, when the folding frame is in use, it is placed with the first end face 11 facing downwards, and the above-mentioned folding furniture is placed with the second end face 21 of the second connecting seat 2 as the support point.
[0036] When the folding furniture using the folding frame is a folding sunshade, a table food cover or a folding mosquito net, etc., referring to Figure 5 as shown, when the folding frame is in use, it is placed with the first end face 11 facing upwards, and the above-mentioned folding furniture is placed with the free end of the second connecting rod 4 or the free end of the third connecting rod 5 as the support point, and then a fabric is covered above or below the first connecting seat 1 and the first connecting rod 3.
[0037] The present utility model provides two embodiments for increasing the number of free ends of the second connecting rod 4 on the premise of keeping the number of the second connecting seats 2 unchanged.
[0038] Embodiment 1 is: Referring to Figure 7As shown, the second connecting seat 2 is provided with a V-shaped hole so that it can connect two second connecting rods 4 at the same time. These two connecting rods are not arranged in parallel, but are staggered with each other in an optimized V-shaped layout. This layout not only effectively disperses the pressure of the fabric or plate on the connection point, but also enhances the connection stability and torsional resistance through the structural characteristics of the V shape. Thus, by keeping the number of second connecting seats 2 unchanged, ensuring that the usage quantities of the second connecting seats 2 and the first connecting rods 3 are not increased, the free ends of the second connecting rods 4 are increased without increasing the manufacturing cost of the folding frame.
[0039] Embodiment 2 is as follows: The free ends of the second connecting rods 4 are two bifurcated rods arranged in a V shape. Through the arrangement of the V-shaped bifurcated rods, additional support points and connection surfaces are provided for the fabric or plate, effectively dispersing the pressure of the fabric or plate on the connection point. Thus, by keeping the number of second connecting seats 2 unchanged, ensuring that the usage quantities of the second connecting seats 2 and the first connecting rods 3 are not increased, the free ends of the second connecting rods 4 are increased without increasing the manufacturing cost of the folding frame.
[0040] When the folding furniture using the folding frame is a folding chair, folding bed or folding table, by increasing the number of free ends of the second connecting rods 4, the connection points between the fabric or plate and the folding frame can be increased, thereby effectively dispersing the pressure of the fabric or plate on the connection point, further enhancing the connection stability between the fabric or plate and the folding frame, and thus improving the overall usage experience and durability.
[0041] When the folding furniture using the folding frame is a folding sunshade, dining table cover or folding mosquito net, etc., by increasing the number of free ends of the second connecting rods 4, there can be more support points between the folding frame and the ground. This design principle of dispersing the support pressure effectively reduces the risk of local overload, significantly enhances the stability and diversity requirements of the folding furniture in various usage scenarios, and avoids deformation problems caused by long-term use or bearing heavy objects or external pressure.
[0042] When the folding furniture using the folding frame is a folding chair, referring to Figures 6 to 8 As shown, at least two free ends of the second connecting rods 4 are provided with a third connecting rod 5. The fabric part connected by the third connecting rod 5 can be used as a backrest for the human body, improving the comfort of use.
[0043] The second connecting rod 4 and the third connecting rod 5 can be connected in the following ways. Specifically, the second connecting rod 4 and the third connecting rod 5 can be connected by integral molding, welding, gluing or plugging and unplugging, etc.
[0044] Referring to Figure 6As shown, the first connecting rod 3, the second connecting rod 4, and the third connecting rod 5 can all achieve a telescopic structure by sleeving an inner tube and an outer tube, that is, by respectively arranging spring pins and a plurality of linearly arranged hole positions on the inner and outer tubes for cooperation. The telescopic property of the first connecting rod 3 is beneficial to reducing the overall size of the folding frame when it is in the storage state. The telescopic structures of the second connecting rod 4 and the third connecting rod 5 can achieve the height adjustment of the folding furniture, improving the convenience of use and adapting to various usage scenarios.
[0045] In addition, the lengths of the respective first connecting rods 3 can be selected to be of different lengths according to the differences of the folding furniture, that is, the lengths of the respective first connecting rods 3 can be set to be equal or unequal.
[0046] In addition, one or two second connecting rods 4 can be selected to be arranged on part of the second connecting seats 2. For example, the folding frame of the folding furniture is provided with eight second connecting seats 2 as fulcrums to support on the ground, and then four of the eight second connecting seats 2 are selected to connect the second connecting rods 4, and then the above-mentioned fabric or plate members are connected to the four second connecting rods 4.
[0047] Both ends of the first connecting rod 3 are respectively rotatably or pluggably connected to the first connecting seat 1 and the second connecting seat 2. Among them, the specific structures of rotation or pluggability can refer to the following two embodiments.
[0048] As a first embodiment, the first connecting rod 3 is rotatably connected to the first connecting seat 1. Specifically, referring to Figure 2 and Figure 3 As shown, the first connecting seat 1 is provided with a first support surface 12 and side plates 13 spaced on both sides of the first support surface 12. The first connecting rod 3 is rotatably connected between the two side plates 13. The first support surface 12 is used to abut against the first connecting rod 3 and keep the first connecting rod 3 in the unfolded state. When the folding frame is in the unfolded state, the first support surface 12 can provide a certain supporting force for the first connecting rod 3.
[0049] As a second embodiment, the first connecting seat 1 is provided with a hole position for inserting the first connecting rod 3. The first connecting rod 3 is inserted into the hole position in a pluggable manner and locked by means of a spring buckle or a screw, etc. As an extension, internal threads can be provided on the inner circumference of the hole position, and the first connecting rod 3 is threadedly connected to the internal threads of the hole position to stably connect the first connecting rod 3 to the first connecting seat 1.
[0050] Similarly, the first connecting rod 3 can be pluggably or rotatably connected to the second connecting seat 2 through the above same structure. One end of the second connecting rod 4 can be pluggably or rotatably connected to the second connecting seat 2 through the above same structure.
[0051] When the second connecting rod 4 and the second connecting seat 2 adopt a pluggable connection method, it further includes an elastic cord 6. The elastic cord 6 passes through the second connecting rod 4 and the second connecting seat 2, and both ends of the elastic cord 6 are fixedly connected to the second connecting rod 4 and the second connecting seat 2 respectively. Therefore, even if the user pulls out the second connecting rod 4 from the second connecting seat 2 to achieve separation between the two, the existence of the elastic cord 6 can ensure that they remain in a connected state, preventing the second connecting rod 4 from completely detaching inadvertently, thereby effectively avoiding the problem of component loss that may occur during the storage or handling of the folding furniture.
[0052] Referring to Figure 2 As shown in the figure, when the folding frame is in the unfolded state, preferably, the second end face 21 of the second connecting seat 2 is a surface parallel to the horizontal plane, thereby increasing the contact area between the folding frame and the ground, enabling the folding frame to be more stably supported by the second connecting seat 2, and preventing the folding frame from shaking during use.
[0053] Referring to Figure 4 As shown in the figure, both ends of the second connecting seat 2 are provided with a first hole 22 and a second hole 23 for the first connecting rod 3 and the second connecting rod 4 to be inserted, as well as a reinforcing rib plate 24 connecting the first hole 22 and the second hole 23. An arc-shaped connecting plate 25 is further provided on the reinforcing rib plate 24, thereby ensuring the strength of the second connecting seat 2 and preventing the second connecting seat 2 from deforming during use.
[0054] Referring to Figure 2 As shown by the angle A in the figure, the included angle between the first connecting seat 1 and the first connecting rod 3 is 65° - 85°, thereby being able to more effectively disperse the force of the user sitting on the folding frame, and improving the overall load-bearing capacity and stability of the folding frame.

[0056] Referring to Figure 7 As shown in the figure, when a folding recliner is made of the folding frame of the present utility model, part A in the figure represents the fabric used. This fabric can be a fabric such as canvas that can bear the weight of the human body. The fabric can be connected to the second connecting rod 4 and the third connecting rod 5 by means of tying with straps, etc. By adding the third connecting rod 5, the fabric in this part can be used as the backrest of the human body, improving the comfort of use.
[0057] Referring to Figure 8As shown, when a folding sun chair is made using the folding frame of the present utility model, part A in the figure represents the fabric used, and the fabric can be canvas or other fabrics capable of bearing the weight of the human body. The fabric can be connected to the second connecting rod 4 and the third connecting rod 5 by means such as tying with straps. By adding the third connecting rod 5, the fabric in this part can be used as the backrest of the human body, improving the comfort of use. A sunshade part B can be connected above the third connecting rod 5, thus forming a folding sun chair.
[0058] Referring to Figure 9 As shown, when a folding hammock or a folding hanging basket is made using the folding frame of the present utility model, it is supported on the ground by more than three second connecting seats 2. Part A in the figure represents the fabric used, and the fabric is connected by selecting symmetrically arranged second connecting rods 4, thus forming a folding hanging basket.
