[0002] In the field of antenna support, foldable tripods are widely used in various scenarios such as mobile communication, field surveying, and emergency support due to their portability and rapid deployment. Current tripods typically rely on complex mechanical structures, such as multi-stage hinges and independent locking systems, designed to ensure stability and adjustability. However, this traditional design has significant limitations.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] like Figures 1 to 5As shown, this utility model provides a foldable support frame, including: a main support part 1 and multiple support legs 2. One end of each support leg 2 is used to connect to the main support part 1, and the other end of each support leg 2 is used to contact the support base surface to jointly support the main support part 1. Each support leg 2 includes multiple connecting tubes 21, which can be connected sequentially in a direction away from the main support part 1 to form an unfolded state or separated from each other to form a folded state. Multiple elastic connectors 3 are arranged one-to-one with the multiple support legs 2. The first end of each elastic connector 3 is connected to the main support part 1, and the second end of each elastic connector 3 passes sequentially through the multiple connecting tubes 21 of the corresponding support leg 2 and connects to the last connecting tube 21 to switch the multiple connecting tubes 21 from the folded state to the unfolded state.

[0031] Technically, this invention utilizes an elastic connector 3 to automatically unfold the support legs 2, avoiding the complexity and failure rate of mechanical hinges in existing technologies, thus improving the reliability and service life of the foldable support frame. In principle, this invention allows for the rapid manual separation of multiple connecting tubes 21, switching them from an unfolded to a folded state. The elastic connector 3 is pre-tensioned when the connecting tubes 21 are folded; when released, the inherent elastic potential energy of the elastic connector 3 is released, propelling the connecting tubes 21 to the unfolded state quickly. In terms of effectiveness, the technology in this invention makes the unfolding and folding process of the foldable support frame extremely fast and simple, solving the problem of high failure rates and low efficiency in the unfolding and folding process of existing foldable support frames due to their complex structures, greatly improving the deployment efficiency of the foldable support frame.

[0032] This utility model's foldable support frame uses pre-tightened elastic connectors 3 that penetrate the interior of the legs as the sole source of kinetic energy, replacing traditional mechanical hinges and other features. This achieves efficient and instantaneous transition from a stored state to a working state without external energy input, improving portability and ease of operation. It ensures synchronous unfolding or folding of each leg 2, greatly reducing the failure rate of the foldable support frame, simplifying maintenance requirements, and achieving a dual improvement in structural stability and unfolding speed. Each elastic connector 3 penetrates the interior of its corresponding leg 2, creating a continuous and efficient kinetic energy transmission path for automatic tripod unfolding. Once multiple connecting tubes 21 are released, the accumulated force of each elastic connector 3 quickly pushes the multiple connecting tubes 21 of each leg 2 into place, without manual intervention, greatly improving operational efficiency and convenience.

[0033] like Figures 1 to 5As shown, the main support part 1 includes a strip support column 11 and an intermediate adapter 12. The intermediate adapter 12 includes a first connection port 121 and a plurality of second connection ports 122. The first connection port 121 is connected to the strip support column 11, and the plurality of second connection ports 122 are used to connect to a plurality of outrigger parts 2 in a one-to-one correspondence. The first ends of a plurality of elastic connectors 3 are connected in a one-to-one correspondence within the plurality of second connection ports 122.

[0034] Technically, the combined design of the strip support column 11 and the intermediate adapter 12 in this invention ensures the structural strength and stability of the main support part 1. In principle, the connection of the multiple second connection ports 122 of the intermediate adapter 12 with the support leg part 2 achieves a uniform distribution of supporting force, ensuring the overall stability of the foldable support frame. In terms of effectiveness, the technology in this invention ensures the structural stability and load-bearing capacity of the foldable support frame when the multiple connecting tubes 21 are in the unfolded state, maintaining good performance even in harsh environments.

[0035] Specifically, there are three support legs 2. The strip support column 11 serves as a sturdy bridge between the supported component and the three support legs 2, and is also key to ensuring a balanced load distribution. It cleverly distributes the entire weight of the supported component evenly to the three support legs 2. The three support legs 2 undertake the main load transfer task, improving the structural stability and load-bearing efficiency of the foldable support frame. The intermediate adapter 12 serves as the central node for the transition from the strip support column 11 to each support leg 2. Its precise design ensures that the three support legs 2 are evenly distributed at 120 degrees to each other, forming a stable triangular support system that can maintain an ideal stable posture regardless of changes in terrain.

[0036] like Figures 1 to 5 As shown, each connecting pipe 21 includes a first pipe section 2101 and a second pipe section 2102 connected to each other. The outer diameter of the first pipe section 2101 is smaller than the inner diameter of the second pipe section 2102. The outer diameters of the first pipe sections 2101 of each connecting pipe 21 are equal, and the inner diameters of the second pipe sections 2102 of each connecting pipe 21 are equal.

[0037] Technically, the nested design among the multiple connecting tubes 21 of this invention allows the foldable support frame to be tightly stored when the multiple connecting tubes 21 are folded, reducing the storage volume of the foldable support frame. In principle, the dimensions of the first tube segment 2101 and the second tube segment 2102 of this invention ensure the smoothness of the foldable support frame during the unfolding and folding process of the multiple connecting tubes 21. In terms of effectiveness, this invention achieves a lightweight and miniaturized foldable support frame, making it easy to carry and store.

[0038] like Figures 1 to 5As shown, the plurality of connecting pipes 21 include: a first connecting pipe 211, wherein the outer diameter of the first segment 2101 of the first connecting pipe 211 is smaller than the inner diameter of the second connecting port 122, for insertion or separation from the corresponding second connecting port 122; a second connecting pipe 212, wherein the first segment 2101 of the second connecting pipe 212 is used for insertion or separation from the second segment 2102 of the first connecting pipe 211; and the second end of each elastic connector 3 is connected to the second connecting pipe 212.

[0039] like Figures 1 to 5 As shown, this invention achieves multi-stage unfolding or folding of the support leg 2 through the combination of the first connecting tube 211 and the second connecting tube 212, reducing the required storage volume of the foldable support frame. In principle, the connection between the second end of the elastic connector 3 and the second connecting tube 212 ensures that the multiple connecting tubes 21 do not disperse in the folded state.

[0040] like Figures 1 to 5 As shown, the plurality of connecting pipes 21 include: a first connecting pipe 211, wherein the outer diameter of the first segment 2101 of the first connecting pipe 211 is smaller than the inner diameter of the second connecting port 122, for insertion or separation from the corresponding second connecting port 122; an intermediate connecting pipe 213, wherein the first segment 2101 of the intermediate connecting pipe 213 is used for insertion or separation from the second segment 2102 of the first connecting pipe 211; a second connecting pipe 212, wherein the first segment 2101 of the second connecting pipe 212 is used for insertion or separation from the second segment 2102 of the intermediate connecting pipe 213; and the second end of each elastic connector 3 is connected to the second connecting pipe 212.

[0041] Technically, this invention achieves multi-stage unfolding or folding of the support leg 2 by adding an intermediate connecting tube 213, thereby improving the structural stability of the foldable support frame. In principle, the connection between the elastic connector 3 and the second connecting tube 212 ensures that the support leg 2 does not disperse in the folded state, while the addition of the intermediate connecting tube 213 enables the foldable support frame to achieve a higher unfolding effect.

[0042] like Figures 1 to 5 As shown, there is one intermediate connecting pipe 213; or, there are multiple intermediate connecting pipes 213 arranged sequentially from the first connecting pipe 211 to the second connecting pipe 212.

[0043] Technically, this invention allows for flexible control of the height range and structural strength of the foldable support frame by adjusting the number of intermediate connecting tubes 213. In principle, the number of intermediate connecting tubes 213 is directly related to the height and stability of the foldable support frame; a higher number results in a taller frame and greater stability. In terms of effectiveness, the technology in this invention can meet the needs of different usage scenarios. Whether a higher height or greater stability is required, it can be achieved by adjusting the number of intermediate connecting tubes 213.

[0044] like Figures 1 to 5 As shown, the second connecting pipe 212 further includes: a tapered pipe section 2103, which is disposed at one end of the second pipe section 2102 of the second connecting pipe 212 away from the first pipe section 2101 of the second connecting pipe 212, for contacting or inserting into the support base surface; or a helical anchor, which is disposed at one end of the second pipe section 2102 of the second connecting pipe 212 away from the first pipe section 2101 of the second connecting pipe 212, for insertion into the support base surface; or a suction cup component, which is disposed at one end of the second pipe section 2102 of the second connecting pipe 212 away from the first pipe section 2101 of the second connecting pipe 212, for contacting the support base surface.

[0045] Technically, this invention enhances the connection stability between the foldable support frame and a supporting base surface such as the ground by incorporating a tapered pipe section 2103, a spiral anchor, or a suction cup component at the end of the second connecting pipe 212, especially on soft or hard surfaces. In principle, the design of these components in this invention increases the friction or anchoring force with different supporting base surfaces, thereby ensuring the stability of the foldable support frame. In terms of effectiveness, the technology in this invention enables the foldable support frame to remain stable under various terrain conditions, improving its usability in field or emergency scenarios.

[0046] like Figures 1 to 5 As shown, the foldable support frame includes a load-bearing hook 4, which is connected to the main support 1 and located between multiple support legs 2 for suspending additional counterweights.

[0047] Technically, this invention, by setting a load-bearing hook 4 on the main support part 1, allows for the suspension of additional counterweights, such as sandbags or batteries, to enhance the wind resistance and stability of the foldable support frame. In principle, the load-bearing hook 4 lowers the center of gravity of the foldable support frame, improving its wind resistance. In terms of effectiveness, the technology in this invention enables the foldable support frame to maintain stability in harsh environments such as strong winds by adding additional counterweights, improving its usability in field or emergency scenarios.

[0048] like Figures 1 to 5 As shown, the foldable support frame also includes a binding component 5, which is used to bind the main support 1 and the multiple connecting pipes 21 together when the multiple connecting pipes 21 are in a folded state.

[0049] Technically, this invention, by incorporating a binding component 5, effectively secures the foldable support frame when the multiple connecting tubes 21 are folded. The volume of the bound foldable support frame is reduced to one-quarter of its volume when the connecting tubes 21 are unfolded, facilitating carrying and storage, and is particularly suitable for confined spaces such as vehicle trunks or aircraft cargo compartments. In principle, the binding component 5 constrains the pre-tension of the elastic connector 3, preventing accidental unfolding of the connecting tubes 21. Effectively, this invention allows the foldable support frame to remain compact when the connecting tubes 21 are folded, facilitating carrying and storage, while ensuring the pre-tension of the elastic connector 3 and improving the unfolding efficiency of the connecting tubes 21.

[0050] like Figures 1 to 5 As shown, the binding component 5 includes: a strip binding part for binding around the main support part 1 and multiple connecting tubes 21; a first connecting part and a second connecting part, which are respectively disposed at both ends of the strip binding part to connect or disconnect the two ends of the strip binding part; wherein, the first connecting part and the second connecting part are hook and loop fasteners that can be glued to each other; or, the first connecting part and the second connecting part are magnetic fasteners that can be magnetically attracted to each other; or, the first connecting part and the second connecting part are snap fasteners that can be interlocked with each other.

[0051] Technically, this invention, by setting a strip-shaped binding part and a first connecting part and a second connecting part located at both ends, enables the rapid fixing and release of the foldable support frame when multiple connecting tubes 21 are in a folded state. In principle, the use of hook-and-loop fasteners, magnetic fasteners, or snap-fit ​​fasteners in this invention makes the binding or releasing operation of the binding part 5 extremely simple. In terms of effectiveness, the technology in this invention makes the folding and unfolding process of the multiple connecting tubes 21 of the foldable support frame extremely rapid and simple, greatly improving the deployment efficiency of the foldable support frame.

[0052] When the first and second connecting parts are magnetically attracted to each other, they can be released in half a second with just one hand, instantly releasing the potential energy of the elastic connecting part 3 and accelerating the deployment speed of the foldable support frame.

[0053] Alternatively, the foldable support frame can be secured in the folded state of the multiple connecting tubes 21 by using other types of binding components 5, such as rubber bands, straps or ropes.

[0054] Among them, the binding component 5 can also be a thermal break rope, whose thermal break mechanism is suitable for rapid release in emergency situations.

[0055] Optionally, the elastic connector 3 includes at least one of an elastic rope and a torsion spring; and / or, the main support 1 is made of at least one of carbon fiber, aluminum alloy and titanium alloy; and / or, the leg 2 is made of at least one of carbon fiber, aluminum alloy and titanium alloy.

[0056] Technically, this invention achieves both lightweight and high strength in the foldable support frame by selecting appropriate materials for the elastic connector 3, main support 1, and outriggers 2. In principle, the selection of these materials is based on their lightweight, high strength, and corrosion resistance, ensuring the stability and durability of the foldable support frame in various environments. In terms of effectiveness, the technology in this invention enables the foldable support frame to achieve lightweight and miniaturization while maintaining structural strength, facilitating portability and storage, and improving its usability in field or emergency scenarios.

[0057] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0058] The foldable support frame of this utility model includes: a main support part 1 and multiple support legs 2. One end of each support leg 2 is connected to the main support part 1, and the other end of each support leg 2 is used to contact a support base surface to jointly support the main support part 1. Each support leg 2 includes multiple connecting tubes 21, which can be connected sequentially in a direction away from the main support part 1 to form an unfolded state or separated to form a folded state. Multiple elastic connectors 3 are arranged one-to-one with each support leg 2. The first end of each elastic connector 3 is connected to the main support part 1, and the second end of each elastic connector 3 passes sequentially through the multiple connecting tubes 21 of the corresponding support leg 2 and connects to the last connecting tube 21 to switch the multiple connecting tubes 21 from the folded state to the unfolded state. Technically, this utility model uses elastic connectors 3 as elastic connectors to achieve automatic unfolding of the support legs 2, avoiding the complexity and failure rate of mechanical hinges in the prior art, and improving the reliability and service life of the foldable support frame. In principle, this invention allows for the rapid manual separation of multiple connecting tubes 21, enabling them to switch from an unfolded to a folded state. The elastic connector 3 is pre-tensioned while the connecting tubes 21 are folded; when the connecting tubes 21 are released, the inherent elastic potential energy of the elastic connector 3 is released, propelling the connecting tubes 21 to the unfolded state quickly. In terms of effectiveness, the technology in this invention makes the unfolding and folding process of the foldable support frame extremely fast and simple, solving the problem of high failure rates and low efficiency in the unfolding and folding process of existing foldable support frames due to their complex structure, thus greatly improving the deployment efficiency of the foldable support frame.
