Description

Technical Field

[0001] This utility model belongs to the field of support technology, and in particular relates to a support structure. Background Technology

[0002] A folding stand is a flexible, adjustable, foldable, and storage rack that can be used in various scenarios. When unfolded, the stand can securely support items, and when not in use, it can be folded away to save space.

[0003] For example, Chinese patent document CN221171698U discloses a highly stable folding bracket, including a support frame. Several symmetrically radially distributed supports are hinged to the upper part of the support frame. A horizontally placed crossbar is fixed to the end of each support. An upper support rod is also hinged to the end of each support. A lower support rod is hinged to the bottom of the upper support rod, and the bottom of the lower support rod is hinged to the lower part of the support frame. A fixed insert rod is movably connected inside the upper support rod, and the fixed insert rod is movably inserted into the lower support rod, causing the upper and lower support rods to form an angle brace between the support and the support frame. After use, pulling up the fixed insert rod allows the bracket to fold downwards under gravity until the upper and lower support rods fold into the support rod cavity. When it is necessary to open the bracket, simply lift the bracket until the fixed insert rod is inserted downwards into the second insertion cavity under gravity, thus fixing the bracket.

[0004] In the aforementioned patent document, the stable folding and unfolding of the folding bracket is achieved by pulling up the fixing rod and inserting it downwards into the second insertion cavity. However, the bracket's unfolding and folding require the fixing rod to extend out of the bracket, making it inconvenient to connect other items above the bracket's support, thus greatly reducing the application range of the folding bracket. Utility Model Content

[0005] The purpose of this invention is to provide a support structure that solves the problem that existing high-stability folding brackets require a fixed insert rod to extend outside the bracket in order to unfold and fold the bracket for storage, thus reducing its application range.

[0006] To achieve the above objectives, this utility model provides a support structure including a first connector, a second connector, and a folding support rod. The first connector and the second connector are movably connected, and both the first connector and the second connector are provided with mounting holes. The two ends of the folding support rod are respectively hinged to the free ends of the first connector and the second connector. The folding support rod includes a first support rod, a second support rod, and a rotating shaft. The first support rod and the second support rod are rotatably connected around the rotating shaft. The second support rod is provided with a positioning component. One end of the first support rod connected to the second support rod is provided with an extension portion, and the extension portion is provided with a positioning hole. The positioning component is positioned on the positioning hole for locking the folding support rod.

[0007] Furthermore, the positioning component includes a positioning element, an elastic element, and a fixing element. The fixing element is located on one side of the second support rod and has a groove inside. The second support rod has a through hole connected to the groove. The elastic element is located in the groove. One end of the positioning element is connected to the elastic element, and the other end extends out of the through hole and is positioned in the positioning hole.

[0008] Furthermore, one end of the positioning member connected to the elastic member extends toward the side wall of the groove with a limiting block, the limiting block being slidably connected to the groove, and the diameter of the limiting block being larger than the diameter of the through hole.

[0009] Furthermore, the first support rod is provided with a sliding groove, one end of which is connected to the positioning hole, and the other end of which passes through the end of the first support rod.

[0010] Furthermore, the end of the positioning member away from the elastic member has an arc-shaped structure.

[0011] Furthermore, the first support rod is provided with a guide groove, which is located on the side of the rotating shaft away from the positioning hole.

[0012] Furthermore, the second connector is provided with a connecting plate, which is bent toward the first connector, and the first connector is rotatably connected to the connecting plate.

[0013] Furthermore, the free end of the connecting plate is provided with a first rotating post, and the first connecting member is provided with a second rotating post, and the first rotating post and the second rotating post are connected by a connecting rod.

[0014] The support structure provided in this embodiment of the utility model has at least the following technical effects:

[0015] Because the positioning component of the second support rod is positioned in the positioning hole of the first support rod, it locks the folding support rod, keeping both the first and second support rods in the unfolded state. The folding support rod is hinged to the first and second connecting pieces respectively, supporting them and improving the stability of the support structure. Since both the first and second connecting pieces have mounting holes, they can be fixed to the product to be folded, expanding the scope of application of the support structure. When storage is required, press the positioning component to disengage it from the positioning hole, then rotate and fold the first and second support rods to complete the folding and storage of the first and second connecting pieces.

[0026] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0027] In one embodiment of the support structure of this utility model, please refer to Figures 1-3 The support structure includes a first connector 100, a second connector 200, and a folding support rod 300. The first connector 100 and the second connector 200 are movably connected, and both the first connector 100 and the second connector 200 are provided with mounting holes 110. The two ends of the folding support rod 300 are respectively hinged to the free ends of the first connector 100 and the second connector 200. The folding support rod 300 includes a first support rod 310, a second support rod 320, and a rotating shaft 330. The first support rod 310 and the second support rod 320 are rotatably connected around the rotating shaft 330. The second support rod 320 is provided with a positioning component 340. One end of the first support rod 310 connecting to the second support rod 320 is provided with an extension 311. The extension 311 is provided with a positioning hole 312. The positioning component 340 is positioned on the positioning hole 312 to lock the folding support rod 300.

[0028] Specifically, the positioning component 340 of the second support rod is positioned in the positioning hole 312 of the first support rod to lock the folding support rod 300, keeping the first support rod 310 and the second support rod 320 in the unfolded state. The folding support rod 300 is hinged to the first connector 100 and the second connector 200 respectively, supporting the first connector 100 and the second connector 200 and improving the stability of the support structure. Since both the first connector 100 and the second connector 200 are provided with mounting holes 110, the first connector 100 and the second connector 200 of the support structure can be fixed to the product to be folded, expanding the application range of the support structure. When storage is required, press the positioning component 340 to disengage it from the positioning hole 312, and then rotate and fold the first support rod 310 and the second support rod 320 to complete the folding and storage of the first connector 100 and the second connector 200.

[0029] Furthermore, the positioning assembly 340 includes a positioning member 341, an elastic member 342, and a fixing member 343. The fixing member 343 is located on one side of the second support rod 320, and a groove 344 is provided inside the fixing member 343. The second support rod 320 is provided with a through hole 321 connected to the groove 344. The elastic member 342 is located inside the groove 344. One end of the positioning member 341 is connected to the elastic member 342, and the other end extends out of the through hole 321 and is positioned inside the positioning hole 312. Specifically, because one end of the positioning member 341 is connected to the elastic member 342 and the other end extends out of the through hole 321, when the second support rod 320 and the first support rod 310 are unfolded, the positioning member 341 first abuts against the first support rod 310 until it moves to the positioning hole 312 and then engages with the positioning hole 312, thereby ensuring that the first support rod 310 and the second support rod 320 are in the unfolded state.

[0030] Furthermore, one end of the positioning member 341 connected to the elastic member 342 extends toward the side wall of the groove 344 with a limiting block 345. The limiting block 345 is slidably connected to the groove 344, and the diameter of the limiting block 345 is larger than the diameter of the through hole 321. Specifically, because the diameter of the limiting block 345 is larger than the diameter of the through hole 321, the positioning member 341 is prevented from fully extending out of the through hole 321 under the action of the elastic member 342, thus avoiding the inability to reset.

[0031] Furthermore, the first support rod 310 is provided with a sliding groove 313, one end of which is connected to the positioning hole 312, and the other end passes through the end of the first support rod 310. Specifically, the sliding groove 313 allows the positioning member 341 to slide into the positioning hole 312 from the sliding groove 313, thereby improving the stability and smoothness of the movement of the positioning member 341.

[0032] Furthermore, the end of the positioning member 341 away from the elastic member 342 has an arc-shaped structure. Specifically, the arc-shaped structure facilitates the positioning member 341 to engage with the positioning hole 312, reducing resistance.

[0033] Furthermore, the first support rod 310 is provided with a guide groove 314, which is located on the side of the rotating shaft 330 away from the positioning hole 312. Specifically, since the first support rod 310 is provided with a guide groove 314 on the side away from the positioning hole 312, when the first support rod 310 and the second support rod 320 are folded and stored, the positioning member 341 slides into the guide groove 314, keeping the first connecting member 100 and the second connecting member 200 in a folded state, thereby preventing them from loosening and separating.

[0034] Furthermore, the second connector 200 is provided with a connecting plate 210, which is bent toward the first connector 100, and the first connector 100 is rotatably connected to the connecting plate 210. Specifically, the connecting plate 210 is used to prevent the first connector 100 and the second connector 200 from being directly rotatably connected at the corner, thereby improving the load-bearing capacity of the support structure.

[0035] Furthermore, the free end of the connecting plate 210 is provided with a first rotating post 220, and the first connecting member 100 is provided with a second rotating post 120. The first rotating post 220 and the second rotating post 120 are connected by a connecting rod. Specifically, the first connecting member 100 rotates around the connecting rod, so that the first connecting member 100 and the second connecting member 200 rotate to achieve unfolding and folding for storage.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
