When one support foot rotates relative to the base under external force, that support foot can simultaneously drive the other support foot to rotate relative to the base via the linkage mechanism. This design achieves relatively convenient deployment and folding of the bracket, and more convenient operation. However, its complex structure and numerous components require precise assembly, resulting in high requirements for manufacturing enterprises, high production costs, and a high barrier to entry for users. Utility Model Content

[0004] The purpose of this utility model is to provide a support structure that aims to solve the technical problem of complex structure in the existing support structure.

[0005] To achieve the above objectives, the present invention provides a support structure, comprising:

[0006] Support rod;

[0007] A sleeve, which is slidably fitted onto the support rod;

[0008] Multiple support leg assemblies, each pivotally connected to the sleeve at its top;

[0009] Each of the aforementioned support foot assemblies includes:

[0010] The outriggers are pivotally connected at their tops to the sleeves;

[0011] A connecting rod, one end of which is provided with a first pivot, so that one end of the connecting rod is pivotally connected to the support rod through the first pivot, and the other end of the connecting rod is pivotally connected to the middle position of the support leg;

[0012] A torsion spring is sleeved on the first pivot. One end of the torsion spring abuts against the support rod, and the other end of the torsion spring abuts against the connecting rod, so that the middle part of the outrigger is driven away from the support rod by the elastic force of the torsion spring, thereby causing the outrigger to unfold.

[0013] Furthermore, it also includes a limiting structure disposed between the support rod and the leg, so that when the leg is folded, the limiting structure can engage to limit the leg to a folded state.

[0014] Furthermore, the limiting structure includes:

[0015] A telescopic limiting component is telescopically disposed at the bottom of the support rod. The bottom of the telescopic limiting component is provided with multiple limiting protrusions, and the multiple limiting protrusions are provided one-to-one with the multiple support legs.

[0016] The structural component extends from the bottom of each leg toward the direction of the support rod. The top of the structural component is provided with a limiting groove so that when the leg is folded, the limiting groove can engage with the limiting protrusion.

[0017] Furthermore, the limiting structure also includes a pop-up switch, which is disposed at the bottom of the telescopic limiting member so that the telescopic limiting member can be moved upward by pressing the pop-up switch upward, so that the limiting protrusion separates from the limiting groove.

[0018] Furthermore, the support leg is provided with a receiving groove on the side facing the support rod, so that the connecting rod can be at least partially received in the receiving groove in the folded state.

[0019] Furthermore, the outrigger has a locking groove at the middle position on one side of the support rod, and the other end of the connecting rod has a second pivot. The connecting rod includes a locking block, so that by inserting the second pivot into the locking groove and locking the locking block into the locking groove, the other end of the connecting rod is pivotally connected to the middle position of the outrigger.

[0020] Furthermore, multiple of the support leg assemblies are pivotally connected to the sleeve at circumferential intervals.

[0021] Furthermore, the outer peripheral surface of the support rod is provided with a locking structure so that when the support leg is in the extended state, the bottom of the sleeve abuts against the locking structure.

[0022] Furthermore, the locking structure is a locking protrusion, and the locking protrusion and the support rod are integrally formed.

[0023] Furthermore, the sleeve includes:

[0024] Inner sleeve, which is slidably fitted onto the support rod;

[0025] An outer sleeve is fixedly fitted onto the outer peripheral surface of the inner sleeve, and the tops of the plurality of legs are rotatably connected to the outer sleeve.

[0026] As can be seen from the above technical solution, the support structure of this utility model simplifies the structure of the drive leg by setting a connecting rod and a torsion spring. The torsion spring provides power for the extension of the support leg. Specifically, one end of the connecting rod is provided with a first pivot and pivotally connected to the support rod, and the other end of the connecting rod is pivotally connected to the middle position of the support leg. The torsion spring is sleeved on the first pivot. The elastic action of the torsion spring can drive the middle of the support leg to move away from the support rod. Since the top of the support leg is pivotally connected to the sleeve, the sleeve moves downward and the support leg will rotate around the top of the support leg, thereby extending the support leg. This achieves the effect of relatively convenient and easy operation for the extension or folding of the support. Moreover, this support structure is simple, with fewer parts and simpler assembly, effectively reducing manufacturing costs and lowering the purchase threshold for users.

[0042] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] It should be noted that, with Figure 1 Based on this, the support structure is placed vertically, with the area above the observer being the top and the area below the observer being the bottom.

[0044] Please refer to the following: Figures 1 to 7 This embodiment provides a support structure, including a support rod 100, a sleeve 200 and a plurality of support foot assemblies 300; the sleeve 200 is slidably fitted onto the support rod 100, and the tops of the plurality of support foot assemblies 300 are respectively pivotally connected to the sleeve 200;

[0045] Each support leg assembly 300 includes a leg 310, a connecting rod 320, and a torsion spring 330. The top of the leg 310 is pivotally connected to the sleeve 200. One end of the connecting rod 320 is provided with a first pivot 321, so that one end of the connecting rod 320 is pivotally connected to the support rod 100 through the first pivot 321. The other end of the connecting rod 320 is pivotally connected to the middle position of the leg 310. The torsion spring 330 is sleeved on the first pivot 321. One end of the torsion spring 330 abuts against the support rod 100, and the other end of the torsion spring 330 abuts against the connecting rod 320, so that the middle part of the leg 310 is driven away from the support rod 100 by the elastic force of the torsion spring 330, thereby causing the leg 310 to unfold.

[0046] As can be seen, the support structure of this embodiment is simple in that it uses a connecting rod 320 and a torsion spring 330 to drive the outrigger 310 to unfold. The torsion spring 330 provides power for the unfolding of the outrigger 310. Specifically, one end of the connecting rod 320 is provided with a first pivot 321 and is pivotally connected to the support rod 100, and the other end of the connecting rod 320 is pivotally connected to the middle position of the outrigger 310. The torsion spring 330 is sleeved on the first pivot 321. The elastic action of the torsion spring 330 can drive the middle part of the outrigger 310 to move away from the support rod 100. Since the top of the outrigger 310 is pivotally connected to the sleeve 200, the outrigger 310 will rotate around the top of the outrigger 310, thereby unfolding the outrigger 310. This achieves the effect of relatively convenient unfolding or folding of the support and easy operation. Moreover, this support structure is simple, with fewer parts and simpler assembly, effectively reducing manufacturing costs and lowering the purchase threshold for users.

[0047] Furthermore, it is understood that when the bottom of the support rod 100 abuts against the plane, the plane is the ground, table, or countertop, etc. When the support leg 310 is extended, the sleeve 200 will slide downwards. The support leg 310 and the connecting rod 320 are made of lightweight rigid materials, preferably aluminum alloy. The torsion spring 330 is made of elastic metal material with good elasticity, preferably steel wire. In this way, the elastic force of the torsion spring 330 is sufficient to drive the middle part of the support leg 310 away from the support rod 100, thereby allowing the support leg 310 to be extended.

[0048] In this embodiment, the bottom of the outer peripheral surface of the support rod 100 is recessed inward to form an installation space. The installation space is used to accommodate one end of the connecting rod 320. The opposite side walls of the installation space are provided with installation holes so that the two ends of the first pivot 321 can be rotatably installed onto the opposite side walls of the installation space through the installation holes. One end of the connecting rod 320 is welded to the first pivot 321 so that one end of the connecting rod 320 is pivotally connected to the support rod 100. During assembly, the torsion spring 330 needs to be sleeved on the first pivot 321 first, and then one end of the connecting rod 320 is welded to the first pivot 321. The torsion spring 330 has a first lever arm and a second lever arm. The first lever arm abuts against the support rod 100, and the second lever arm abuts against the connecting rod 320. A first limiting groove for accommodating the second lever arm is also provided on the side of the connecting rod 320 near the support rod 100. A second limiting groove for accommodating the first lever arm is also provided on the top of the installation space so that the elastic force of the torsion spring 330 is stable.

[0049] In this embodiment, as Figure 1 and Figure 7 As shown, the support structure also includes a limiting structure, which is set between the support rod 100 and the leg 310. When the leg 310 is folded, the limiting structure can engage so that the leg 310 is limited to the folded state. The overall volume after folding is reduced, making it easier for users to put the support into backpacks, suitcases, and other spaces, thus improving portability.

[0050] When the support leg 310 is folded up, the limiting structure locks the support leg 310 in the folded position through a locking action, preventing the support leg 310 from automatically unfolding due to external force shaking or collision during transportation, storage or non-use, thus improving safety and reliability. When the support leg 310 is in the folded position, the length direction of the support leg 310 and the connecting rod 320 is parallel to the length direction of the support rod 100, so as to effectively reduce the volume of the support structure when it is folded up and improve the neatness of the product.

[0051] Preferably, the limiting structure includes a telescopic limiting member 410 and a structural member 420. The telescopic limiting member 410 is telescopically disposed at the bottom of the support rod 100. The bottom of the telescopic limiting member 410 is provided with a plurality of limiting protrusions 411, which are provided one-to-one with a plurality of support legs 310. The structural member 420 is formed by protruding from the bottom of each support leg 310 in the direction of the support rod 100. The top of the structural member 420 is provided with a limiting groove 421 so that when the support leg 310 is folded, the limiting groove 421 can engage with the limiting protrusion 411.

[0052] The bottom of the support rod 100 is a hollow tubular structure, and a compression spring is installed at the top inside the hollow tubular structure. The top of the telescopic limiting member 410 abuts against one end of the compression spring, so that the telescopic limiting member 410 can be telescopically installed at the bottom of the support rod 100. When the telescopic limiting member 410 is in the extended state, the limiting protrusion 411 is embedded in the limiting groove 421 to form a mechanical interlock. The locking interface is tightly fitted and can withstand a large external force. When the telescopic limiting member 410 retracts upward into the support rod 100, that is, when the compression spring is in the contracted state, the limiting protrusion 411 will disengage upward from the limiting groove 421. Then, the elastic force of the torsion spring 330 will drive the middle part of the support leg 310 away from the support rod 100, thereby causing the support leg 310 to unfold.

[0053] Furthermore, the limiting structure also includes a pop-up switch 430, which is disposed at the bottom of the telescopic limiting member 410 so that the telescopic limiting member 410 can be moved upward by pressing the pop-up switch 430 upward, so that the limiting protrusion 411 separates from the limiting groove 421.

[0054] Specifically, the pop-up switch 430 is located at the bottom of the telescopic limiting member 410. In the folded state, the bottom of the pop-up switch 430 extends out from the bottom of the support leg 310. When the pop-up switch 430 is pressed, the telescopic limiting member 410 moves upward as a whole, causing all the limiting protrusions 411 to simultaneously disengage from the limiting groove 421, thus unlocking all the support legs 310 at once. Furthermore, no complex structure is required for unlocking; typically, simply slamming the support rod 100 down into the ground will cause all the support legs 310 to unfold at once.

[0055] Preferably, the support leg 310 is provided with a receiving groove 311 along its length on the side facing the support rod 100, so that the connecting rod 320 can be received in the receiving groove 311 in the folded state. The shape of the receiving groove 311 matches the end contour of the connecting rod 320. When the connecting rod 320 is embedded in the receiving groove 311, the side wall of the receiving groove 311 can restrict the lateral movement and rotation of the connecting rod 320, so as to prevent the connecting rod 320 from being displaced due to vibration or collision after folding. Moreover, this arrangement can make the bracket structure compact, reduce the size of the bracket, and facilitate carrying.

[0056] Furthermore, the outrigger 310 has a locking groove 312 at the middle position on the side facing the support rod 100, and the other end of the connecting rod 320 has a second pivot. The connecting rod 320 includes a locking block 323, so that by inserting the second pivot into the locking groove 312 and locking the locking block 323 into the locking groove 312, the other end of the connecting rod 320 is pivotally connected to the middle position of the outrigger 310.

[0057] The second pivot is fixed to the other end of the connecting rod 320. The fastening block 323 is provided with a fastening protrusion, and the fastening groove 312 is provided with a fastening space corresponding to the fastening protrusion, so that the fastening block 323 can be fastened and installed into the fastening groove 312. In other embodiments, the fastening block 323 can be bonded or welded into the fastening groove 312.

[0058] Furthermore, such as Figure 6 and Figure 7 As shown, multiple support leg assemblies 300 are pivotally connected to the sleeve 200 at circumferential intervals. This circumferential spacing ensures the support leg assemblies 300 are evenly arranged around the support rod 100. In the unfolded state, the supporting force of each leg 310 on the support rod 100 can be evenly distributed in different directions. If the support leg assemblies 300 are concentrated on one side, it may cause the overall center of gravity of the support to shift or tilt. The circumferential spacing improves the stability of the support through a symmetrical structure, making it particularly suitable for scenarios requiring heavy loads or balance. The evenly distributed structure facilitates the synchronous unfolding or folding of all legs 310 by the sliding of the sleeve 200. For example, when the sleeve 200 slides down, each leg 310 is synchronously pushed outward by the connecting rod 320 and the torsion spring 330, improving ease of use. When carrying objects, the circumferentially distributed legs 310 can distribute the load from multiple directions, making it particularly suitable for scenarios requiring resistance to multi-angle external forces.

[0059] In this embodiment, the outer peripheral surface of the support rod 100 is provided with a locking structure 110 so that when the support leg 310 is in the unfolded state, the bottom of the sleeve 200 abuts against the locking structure 110, the sleeve 200 no longer moves downward, and the support leg 310 completes unfolding and reaches the maximum unfolded position.

[0060] Furthermore, the locking structure 110 is a locking protrusion, and the locking protrusion and the support rod 100 are integrally formed. Preferably, the support rod 100 is made of aluminum alloy, and the locking protrusion and the support rod 100 are integrally stamped. This structure is simple and has a low cost.

[0061] In this embodiment, the sleeve 200 includes an inner sleeve 210 and an outer sleeve 220. The inner sleeve 210 is slidably sleeved on the support rod 100, and the outer sleeve 220 is fixedly sleeved on the outer peripheral surface of the inner sleeve 210. The tops of the multiple support legs 310 are rotatably connected to the outer sleeve 220.

[0062] The inner sleeve 210 is directly fitted onto the support rod 100 to achieve a sliding function; the outer sleeve 220 is fixed to the outside of the inner sleeve 210 and serves as a pivotal connection carrier for the support foot assembly 300. The length of the inner sleeve 210 is greater than the length of the outer sleeve 220. The sleeve 200 also includes a rubber sleeve, which is fitted onto the inner sleeve 210 to form a handheld surface 500 on the outer surface of the rubber sleeve. The handheld surface 500 can also be used to attach advertising patterns, etc.

[0063] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0064] The structure of the outrigger 310 is simplified by using a connecting rod 320 and a torsion spring 330. The torsion spring 330 provides power for the outrigger 310 to unfold. Specifically, one end of the connecting rod 320 is provided with a first pivot 321 and pivotally connected to the support rod 100, and the other end of the connecting rod 320 is pivotally connected to the middle position of the outrigger 310. The torsion spring 330 is sleeved on the first pivot 321. The elastic action of the torsion spring 330 can drive the middle of the outrigger 310 to move away from the support rod 100. Since the top of the outrigger 310 is pivotally connected to the sleeve 200, the outrigger 310 will rotate around the top of the outrigger 310, thereby unfolding the outrigger 310. This achieves the effect of relatively convenient unfolding or folding of the bracket and easy operation. Moreover, this bracket structure is simple, with fewer parts and simpler assembly, effectively reducing manufacturing costs and lowering the purchase threshold for users.
