Description

Technical Field

[0001] This application relates to the field of mechanics, and more specifically, to a connecting rod. Background Technology

[0002] A connecting rod is a type of rod formed by connecting multiple segments together. After use, the connecting rod can be disassembled into individual segments for easy storage. Before use, it is reassembled into a connecting rod by connecting the multiple segments together.

[0003] In the existing technology, various simple detachable connections between multiple connecting rods do improve the retractability of the connecting rods.

[0004] However, when multiple connecting rods are disassembled into individual rods, it's easier for rods to be lost. Furthermore, each rod needs to be identified before reassembly, wasting unnecessary time. This is especially true when used with tent frames for easy storage; while detachable rods facilitate storage after disassembly, the need to identify each rod before reassembly further delays the process. Summary of the Invention

[0005] The purpose of this application is to provide a connecting rod that connects links via connecting ropes, which can prevent the loss or disorder of the links and thus save time during assembly.

[0006] This application provides a connecting rod, including an elastic connecting rope, a first connecting rod, an intermediate connecting rod, and a tail connecting rod. The elastic connecting rope connects the first connecting rod, the intermediate connecting rod, and the tail connecting rod. The intermediate connecting rod includes a first connecting end and a second connecting end. One of the first connecting end and the second connecting end includes a first connecting portion located at the end of the connecting end, and a first connecting portion connected to the first connecting portion and located away from the end of the connecting end. The other of the first connecting end and the second connecting end includes a second connecting portion located at the end of the connecting end. The first connecting portion is configured to be detachably connected to the second connecting portion. The first connecting portion is configured to engage with a joint member by a snap-fit ​​mechanism to connect the connecting rod to the joint member.

[0007] The aforementioned connecting rod uses an elastic connecting rope to connect its first connecting rod, middle connecting rod, and tail connecting rod. This prevents the loss of any components when the connecting rod is in a disassembled state, where the first, middle, and tail connecting rods are detached from each other. Furthermore, the elastic connection ensures that the order of the components remains consistent even when the connecting rod is disassembled, eliminating the need for identification of the components before assembly. Additionally, the elastic connecting rope automatically adjusts its length regardless of whether the connecting rod is in a disassembled or assembled state, further improving the convenience of the connecting rod. Moreover, the first joint for engaging with joint components enhances the reliability of the assembled connecting rod when connected to joint components or other parts. It also improves the stability of the devices adapted to these other parts.

[0008] Optionally, the elastic connecting rope is specifically formed by passing through the first connecting rod, the middle connecting rod, and the tail connecting rod to form the connecting rod.

[0009] The aforementioned connecting rod simplifies the manufacturing process by using an elastic connecting rope that runs through the first connecting rod, the middle connecting rod, and the tail connecting rod.

[0010] Optionally, the elastic connecting rope is specifically formed by connecting the ends of two of the first connecting rod, the middle connecting rod, and the tail connecting rod to form the connecting rod.

[0011] The aforementioned connecting rod connects the ends of the segments that make up the connecting rod, thus achieving the series connection of the segments. This saves material used in making the elastic connecting rope.

[0012] Optionally, one of the first connecting portion and the second connecting portion is provided with an internal thread. The other of the first connecting portion and the second connecting portion is provided with an external thread that matches the internal thread.

[0013] The aforementioned connecting rods only require tapping the first and second connecting parts to enable each intermediate connecting rod to be detachable, thus simplifying the manufacturing process.

[0014] Optionally, one of the first connecting portion and the second connecting portion is provided with a first fastening member. The other of the first connecting portion and the second connecting portion is provided with a second fastening member that matches the first fastening member.

[0015] The aforementioned connecting rod is detachable via a snap-fit ​​mechanism, which further improves the assembly speed of the connecting rod.

[0016] Optionally, the joint member has an open groove for receiving the first connecting portion. The surface of the joint member is provided with inwardly recessed anti-slip countersinks along the edges of both ends of the groove. The diameter of the first connecting portion is smaller than the inner diameter of the groove and smaller than the diameter of the connecting rod. The diameter of the connecting rod matches the inner diameter of the anti-slip countersink. A step is formed at the end of the intermediate connecting rod where the first connecting portion connects to the first connecting portion. When the first connecting portion connects to the second connecting portion and the first connecting portion is engaged in the groove, the step abuts against the anti-slip countersink, and the connecting end of the intermediate connecting rod where the second connecting portion is located abuts against the anti-slip countersink.

[0017] When the connecting rod is engaged in the groove of the joint, the step on the connecting rod that matches the anti-slip sinking platform abuts against the anti-slip sinking platform, preventing the connecting rod from slipping out of the joint.

[0018] Optionally, one of the first connecting portion and the second connecting portion is provided with a protrusion extending outward along the length direction of the intermediate connecting rod. The other of the first connecting portion and the second connecting portion is provided with a recess extending inward along the length direction of the intermediate connecting rod and matching the protrusion.

[0019] The aforementioned connecting rod, by providing a protrusion extending outward along the length of the intermediate connecting rod in one of the first connecting part and the second connecting part, and a corresponding recess in the other, eliminates the need for further thread processing, thus further simplifying the manufacturing process.

[0020] Optionally, the joint member has a slot for receiving the first connecting portion, and flanges extend from the edges of both ends of the slot inward. One of the first and second connecting ends, each including the second connecting portion, further includes a first neck connected to the first connecting portion and located away from the end of the connecting end. The other of the first and second connecting ends, each including the second connecting portion, further includes a second connecting portion connected to the second connecting portion and located away from the end of the connecting end, and a second neck connected to the second connecting portion and located away from the end of the connecting end. The second connecting portion is configured to engage with the joint member by a snap-fit ​​mechanism. The diameters of the first and second connecting portions are greater than the inner diameter of the flanges and smaller than the inner diameter of the slot. The diameters of the first and second necks are smaller than the inner diameter of the flanges.

[0021] The aforementioned connecting rod, by providing a first neck and a second neck respectively at the first connecting part and the second connecting part, wherein the diameters of the first neck and the second neck are matched with the inner diameter of the slot and the inner diameter of the flange on the slot, respectively. When the first connecting part and the second connecting part are engaged inside the slot, the sliding movement of the connecting rod in its length direction is restricted.

[0022] Optionally, the diameters of the first and second connecting portions match the diameter of the slot. When the first connecting portion is connected to the second connecting portion, and the first and second connecting portions are engaged with the joint in the slot, the flanges abut against the first and second connecting portions respectively.

[0023] When the first and second connecting parts of the aforementioned connecting rod are engaged in the slot, there will be no gap between the connecting rod and the slot or between the connecting rod and the flange, thus improving the stability of the connection between the connecting rod and the joint.

[0024] Optionally, the intermediate link further includes a link body connected between the first neck and the second neck. The first neck and the second neck are detachably connected to the link body.

[0025] The aforementioned connecting rod has a first neck and a second neck that are detachably connected to the connecting rod body. This allows for separate processing and manufacturing of each part of the intermediate connecting rod during the manufacturing process, avoiding the complexity of mold opening required in one-piece molding. It also facilitates the replacement of parts.

[0026] Optionally, the first connecting rod includes one of the first connecting portion and the second connecting portion. The tail connecting rod includes the other of the first connecting portion and the second connecting portion.

[0027] The aforementioned connecting rods, by providing a first connecting part and a second connecting part to the first connecting rod and the tail connecting rod respectively, enable the assembly of the first connecting rod and the tail connecting rod with the intermediate connecting rod.

[0028] Optionally, the materials used to manufacture the first connecting rod, the intermediate connecting rod, and the tail connecting rod include at least one of carbon fiber, glass fiber composite material, and aluminum alloy.

[0029] The aforementioned connecting rods, made of carbon fiber, glass fiber composite material, and aluminum alloy, are high-strength and lightweight materials. Using at least one of these materials as the material for the first connecting rod, intermediate connecting rod, and tail connecting rod ensures the strength of the connecting rod while reducing its weight.

[0030] Optionally, the connecting rod is adapted to a tent frame. The tent frame includes a first support gantry and a second support gantry, both of which include a support rod rotatably connected by the joint. The connecting rod connects the first support gantry and the second support gantry by engaging with the joint.

[0031] The aforementioned connecting rods, when adapted to the tent frame and connected to each mast, allow the tent frame to extend at appropriate intervals for use. When the connecting rods are removed from the masts, they can be disassembled using the detachable first, middle, and last connecting rods, facilitating storage. Furthermore, the connecting rods are linked together by elastic connecting ropes, preventing the loss of any components and ensuring the correct order of the parts. When the tent frame is to be used again, there is no need to identify the parts to determine their assembly order; they can be directly assembled and connected to the masts. This reduces the overall assembly time of the tent frame by saving time on the connecting rods.

[0032] The connecting rod provided in this application achieves assembly and disassembly through the detachable connection between the first connecting rod, the intermediate connecting rod, and the tail connecting rod, facilitating the storage of the connecting rod. An elastic connecting rope connects the first connecting rod, the intermediate connecting rod, and the tail connecting rod, preventing the loss of components and disruption of their sequence when the connecting rod is in a disassembled state. The first connecting rod, the intermediate connecting rod, and the tail connecting rod can be connected in series by a single elastic connecting rope running through them, simplifying the manufacturing process. Alternatively, multiple elastic connecting ropes can be used, or they can be connected by connecting the ends of two of the first connecting rods, the intermediate connecting rod, and the tail connecting rod, saving material for manufacturing the elastic rope. The anti-slip countersinks or flanges on the connecting rod's joint portion, which cooperate with the joint component's groove, improve the stability and reliability of the connection between the connecting rod and the joint component. In particular, when the connecting rod provided in this application is adapted to the tent frame, it not only improves the stability of the tent frame, but also facilitates the storage of the tent frame after use and shortens the assembly time when the tent frame is put back into use.

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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 some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0046] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0047] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0048] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0049] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0050] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0051] Please refer to Figures 1 to 4 , Figure 1This is a schematic diagram of the first type of connecting rod 100 in a folded state provided in an embodiment of this application; Figure 2 This is a schematic diagram of the second type of connecting rod 100 in a folded state provided in an embodiment of this application; Figure 3 This is a schematic diagram of the first type of intermediate connecting rod 120 provided in the embodiments of this application; Figure 4 This is a schematic diagram of the assembled state of the connecting rod 100 provided in an embodiment of this application. The connecting rod 100 includes an elastic connecting rope 140, a first connecting rod 110, an intermediate connecting rod 120, and a tail connecting rod 130. The elastic connecting rope 140 connects the first connecting rod 110, the intermediate connecting rod 120, and the tail connecting rod 130. The intermediate connecting rod 120 includes a first connecting end 121 and a second connecting end 122. One of the first connecting end 121 and the second connecting end 122 includes a first connecting portion 1211 located at the end of the connecting end, and a first connecting portion 1212 connected to the first connecting portion 1211 and located away from the end of the connecting end. The other of the first connecting end 121 and the second connecting end 122 includes a second connecting portion 1221 located at the end of the connecting end. The first connecting portion 1211 is configured to be detachably connected to the second connecting portion 1221. The first connecting portion 1212 is configured to engage with the joint member 200 by a snap-fit ​​method to connect the connecting rod 100 to the joint member 200.

[0052] The aforementioned connecting rod 100 may include only one intermediate connecting rod 120. In this case, the connecting rod 100 would consist of only three rod segments: a first connecting rod 110, an intermediate connecting rod 120, and a tail connecting rod 130. Alternatively, the connecting rod 100 may include at least two intermediate connecting rods 120, with each connecting rod still connected by an elastic connecting rope 140. In this case, the connecting rod 100 would consist of several end rods. Therefore, the specific number of rod segments that the connecting rod 100 may consist of can be determined by those skilled in the art based on the embodiments of this application and actual needs. This application does not impose specific limitations in this regard.

[0053] The elastic connecting rope 140 is telescopic. The first connecting rod 110, the middle connecting rod 120 and the tail connecting rod 130 of the connecting rod 100 are connected by the elastic connecting rope 140. Whether the connecting rod 100 is in a combined state where the connecting rods are assembled together by means of detachable connection or in a disassembled state, the elastic rope can adjust its length adaptively by means of its own telescopicity.

[0054] Exemplarily, the connecting rod 100 has a coupling portion for engaging with a joint member 200 (i.e., an external structure) to achieve the connection of the joint members 200. The joint member 200 has an open slot for receiving the first coupling portion 1212, and a limiting device to prevent the first coupling portion 1212 from sliding within the slot along the length direction of the intermediate connecting rod 120 and from slipping out of the slot. This improves the stability of the connection between the connecting rod 100 and the joint member 200. It is worth noting that the connecting rod 100 can also be connected to other external structures that can engage with the first coupling portion 1212; this application does not limit the specific structure of the external structure engaging with the connecting rod 100.

[0055] In the above implementation process, an elastic connecting rope 140 is used to connect the first connecting rod 110, the intermediate connecting rod 120, and the tail connecting rod 130 of the connecting rod 100. When the connecting rod 100 is in a disassembled state where the first connecting rod 110, the intermediate connecting rod 120, and the tail connecting rod 130 are detached from each other, the loss of each part constituting the connecting rod 100 is prevented. At the same time, by elastically connecting each part, the order of each part will not be disordered when the connecting rod 100 is in a disassembled state, saving the time of identifying each part of the connecting rod 100 before assembly. In addition, by connecting the first connecting rod 110, the intermediate connecting rod 120, and the tail connecting rod 130 of the connecting rod 100 with the elastic connecting rope 140, the elastic connecting rope 140 can adjust its own length regardless of whether the connecting rod 100 is in a disassembled or assembled state, further improving the convenience of the connecting rod 100. Furthermore, the first engagement portion 1212 provided for engaging with the joint member 200 enhances the reliability of the assembled connecting rod 100 when it is connected to other parts such as the joint member. It also improves the stability of the device to which these other parts are adapted.

[0056] Please refer to the following for details. Figure 1 In one alternative embodiment, the elastic connecting rope 140 is specifically formed by passing through the first connecting rod 110, the middle connecting rod 120 and the tail connecting rod 130 to form the connecting rod 100.

[0057] In this embodiment of the application, the first connecting rod 110, the middle connecting rod 120 and the tail connecting rod 130 of the connecting rod 100 can be tubular hollow rods, and the elastic connecting rope 140 connects them together by passing through the hollow parts inside the first connecting rod 110, the middle connecting rod 120 and the tail connecting rod 130.

[0058] In this embodiment, regarding the fixing method of the elastic connecting rope 140 in the connecting rod 100, the elastic connecting rope 140 can be fixed at both ends of the connecting rod 100, that is, when the first connecting rod 110, the intermediate connecting rod 120, and the tail connecting rod 130 are assembled together by a detachable connection, the ends of the first connecting rod 110 and the tail connecting rod 130 away from the intermediate connecting rod 120. The elastic connecting rope 140 can also be fixed in the middle of the first connecting rod 110 and the tail connecting rod 130. Alternatively, the elastic connecting rope 140 can be fixed at the ends of the first connecting rod 110 and the tail connecting rod 130 near the intermediate connecting rod 120. In all three fixing methods described above, the remaining portion of the elastic connecting rope 140, except for the two ends, is not fixed to any part of the connecting rod 100.

[0059] In another embodiment of this application, another possible way to fix the elastic connecting rope 140 is that the middle part of the elastic connecting rope 140 is fixed to all the corresponding first connecting rods 110, intermediate connecting rods 120 and tail connecting rods 130. The elastic connecting rope 140 can be fixed to some of the connecting rods among the first connecting rods 110, intermediate connecting rods 120 and tail connecting rods 130.

[0060] Those skilled in the art can choose the above-described fixing method to fix the elastic connecting rope 140 to the connecting rod 100 according to actual needs, or they can use a fixing method other than the above-described fixing method to fix the elastic connecting rope 140 to the connecting rod 100. This application embodiment does not impose specific limitations in this regard.

[0061] In the above implementation process, the manufacturing process is simplified by using an elastic connecting rope 140 to pass through the first connecting rod 110, the middle connecting rod 120 and the tail connecting rod 130 of the connecting rod 100.

[0062] Please refer to the following for details. Figure 2 In one optional embodiment, the elastic connecting rope 140 is specifically formed by connecting the ends of two of the first connecting rod 110, the middle connecting rod 120 and the tail connecting rod 130 to form the connecting rod 100.

[0063] The aforementioned connecting rod 100 includes multiple elastic connecting ropes 140, the specific number of which is determined by the number of rods constituting the connecting rod 100.

[0064] Preferably, if the number of rods constituting the connecting rod 100 is N, then the number of elastic connecting ropes 140 is N-1.

[0065] The elastic connecting rope 140 connects the ends of two rods of the first connecting rod 110, the middle connecting rod 120 and the tail connecting rod 130 that are close to each other, thereby connecting the first connecting rod 110, the middle connecting rod 120 and the tail connecting rod 130 together.

[0066] In the above implementation process, the segments of the connecting rod 100 are connected by linking the ends of the segments. This saves material used in manufacturing the elastic connecting rope 140.

[0067] In one alternative embodiment, one of the first connecting portion 1211 and the second connecting portion 1221 is provided with an internal thread. The other of the first connecting portion 1211 and the second connecting portion 1221 is provided with an external thread that matches the internal thread.

[0068] In the above implementation process, only the first connecting part 1211 and the second connecting part 1221 need to be tapped to enable each intermediate connecting rod 120 to have a detachable function, which simplifies the manufacturing process.

[0069] In one alternative embodiment, one of the first connecting portion 1211 and the second connecting portion 1221 is provided with a first fastening member. The other of the first connecting portion 1211 and the second connecting portion 1221 is provided with a second fastening member that matches the first fastening member.

[0070] In the above process, a detachable connection is achieved through a snap-fit ​​mechanism, which further improves the assembly speed of the connecting rod 100.

[0071] Please refer to Figure 5 and Figure 6 , Figure 5 A schematic diagram of the external structure that can be matched with the connecting rod 100, provided for an embodiment of this application; Figure 6 This is a perspective view of the first type of connecting rod provided in this application when combined with an external structure. In an optional embodiment, the external structure includes a joint 200, which has a groove 210 for receiving a first connecting portion 1212. The surface of the joint 200 has inwardly recessed anti-slip recesses 220 along the edges of both ends of the groove 210. The diameter of the first connecting portion 1212 is smaller than the inner diameter of the groove 210 and smaller than the diameter of the connecting rod 100. The diameter of the connecting rod 100 matches the inner diameter of the anti-slip recesses 220. A step is formed at the end of the intermediate connecting rod 100 where the first connecting portion 1212 connects to the first connecting portion 1211. When the first connecting part 1211 is connected to the second connecting part 1221 and the first connecting part 1212 is engaged in the slot 210, the step abuts against the anti-slip sinking platform 220, and the connecting end of the intermediate connecting rod 100 provided with the second connecting part 1221 abuts against the anti-slip sinking platform 220.

[0072] The connecting rod 100 engages with the joint member 200 via a slot 210 formed on the joint member 200, thereby connecting the connecting rod 100 and the joint member 200. The diameter of the engaging part must be smaller than the inner diameter of the slot 210 to allow the slot 210 to receive the engaging part.

[0073] When the clamp of the joint is in the groove 210, in order to prevent it from slipping out of the groove 210, anti-slip countersinks 220 are provided at both ends of the groove 210 along its edge.

[0074] Preferably, the end face of the anti-slip sinking platform 220 is an arc surface, and the arc formed by the projection of this arc surface has a curvature greater than π. The width of the opening of the arc surface is less than the diameter of the connecting rod 100.

[0075] When assembling the joint 200, the joint can be placed in the slot 210 first, and then the first connecting rod 110, the middle connecting rod 120 and the tail connecting rod 130 in the connecting rod 100 can be assembled in a detachable manner, so that the step formed at the end where the first joint 1212 is connected to the first connecting part 1211 abuts against the anti-slip sinking platform 220.

[0076] During the above process, when the joint is engaged in the slot 210 of the joint member 200, the step on the connecting rod 100 that matches the anti-slip support abuts against the anti-slip countersink 220, preventing the connecting rod 100 from slipping out of the joint member 200.

[0077] Please refer to Figure 7 , Figure 7 This is a schematic diagram of a second type of intermediate connecting rod 120 structure provided in an embodiment of this application. In an optional embodiment, one of the first connecting portion 1211 and the second connecting portion 1221 is provided with a protrusion 1214 extending outward along the length direction of the intermediate connecting rod 120. The other of the first connecting portion 1211 and the second connecting portion 1221 is provided with a recess 1224 extending inward along the length direction of the intermediate connecting rod 120 and matching the protrusion 1214.

[0078] The aforementioned protrusion 1214 may not have external threads, and the aforementioned recess 1224 may not have internal threads. During assembly, the connecting rod 100 is assembled by inserting the protrusion 1214 into the recess 1224, thereby achieving a detachable connection between the first connecting rod 110, the middle connecting rod 120, and the tail connecting rod 130. The connecting rod 100 provided in this embodiment can be used as a support rod 311 for supporting sunshade nets, camouflage nets, etc.

[0079] In the above implementation process, by providing a protrusion 1214 extending outward along the length direction of the intermediate connecting rod 120 on one of the first connecting part 1211 and the second connecting part 1221, and providing a recessed part 1224 that cooperates with it on the other, the manufacturing process is further simplified without the need to process threads.

[0080] Please refer to Figure 8 and Figure 9 , Figure 8This is a top view of the second type of connecting rod 100 combined with an external structure according to an embodiment of this application; Figure 9 This is a perspective view of the second type of connecting rod 100 provided in this application embodiment when combined with an external structure. In an optional embodiment, the external structure is also described using the joint member 200 as an example. The joint member 200 has a slot 210 for receiving the first connecting portion 1212, and flanges 230 extend from the edges at both ends of the slot 210 inward. One of the first connecting end 121 and the second connecting end 122, which includes the second connecting portion 1221, further includes a first neck 1213 connected to the first connecting portion 1212 and located away from the end of the connecting end. The other of the first connecting end 121 and the second connecting end 122, which includes the second connecting portion 1221, further includes a second connecting portion 1222 connected to the second connecting portion 1221 and located away from the end of the connecting end, and a second neck 1223 connected to the second connecting portion 1222 and located away from the end of the connecting end. The second connecting portion 1222 is configured to engage with the joint member 200 by a snap-fit ​​mechanism. The diameters of the first joint 1212 and the second joint 1222 are greater than the inner diameter of the flange 230 and smaller than the inner diameter of the slot 210. The diameters of the first neck 1213 and the second neck 1223 are smaller than the inner diameter of the flange 230.

[0081] When the first connecting end 121 and the second connecting end 122 are engaged together, the protrusion 1214 and the recess 1224 restrict the misalignment movement between the first connecting end 121 and the second connecting end 122. When the first connecting part 1212 is engaged in the slot 210, the end faces of the first connecting part 1212 and the second connecting part 1222 facing away from each other are abutted by the flange 230 inside the slot 210, restricting their movement in the length direction of the connecting rod 100.

[0082] Preferably, the joint 200 is provided with a rotatable rotating hook. When the first connecting part 1212 and the second connecting part 1222 are engaged in the slot 210, the rotating hook rotates to engage the first neck 1213 and / or the second neck 1223, further preventing the first connecting part 1212 and the second connecting part 1222 from slipping out of the slot 210. The number of rotating hooks can be one, which can engage either the first neck 1213 or the second neck 1223. The number of rotating hooks can be two, which can engage the first neck 1213 and the second neck 1223 respectively. When there are two rotating hooks, the first connecting part 1211 and the second connecting part 1221 do not need to have corresponding protrusions 1214 and recesses 1224.

[0083] In the above implementation process, a first neck 1213 and a second neck 1223 are respectively provided in the first connecting part 1211 and the second connecting part, and the diameters of the first neck 1213 and the second neck 1223 are matched with the inner diameter of the slot 210 and the inner diameter of the flange 230 on the slot 210. When the first connecting part 1212 and the second connecting part 1222 are engaged in the slot 210, the sliding of the connecting rod 100 in its length direction is restricted.

[0084] Please continue to refer to Figure 8 and Figure 9 In one optional embodiment, the diameters of the first connecting portion 1212 and the second connecting portion 1222 match the diameter of the slot 210. When the first connecting portion 1211 and the second connecting portion 1221 are connected, and the first connecting portion 1212 and the second connecting portion 1222 are engaged with the joint member 200 in the slot 210, the flange 230 abuts against the first connecting portion 1212 and the second connecting portion 1222 respectively.

[0085] The diameters of the first connecting portion 1212 and the second connecting portion 1222 match the diameter of the slot 210. This means that when the first connecting portion 1212 and the second connecting portion 1222 are fitted into the slot 210, the arc surfaces on the outer surfaces of the first connecting portion 1212 and the second connecting portion 1222 fit against the inner arc surfaces on the inner surfaces of the slot 210.

[0086] When the first connecting part 1211 and the second connecting part 1221 are assembled by a detachable connection, the end faces of the first connecting part 1212 and the second connecting part 1222 facing away from each other can abut against the flange 230 of the slot 210.

[0087] In the above implementation process, when the first connecting part 1212 and the second connecting part 1222 are engaged in the slot 210, there will be no gap between them and the slot 210 and between them and the flange 230, which improves the stability of the connection between the connecting rod 100 and the joint 200.

[0088] Please continue to refer to Figure 8 and Figure 9 In one optional embodiment, the intermediate link 120 further includes a link body connected between the first neck 1213 and the second neck 1223. The first neck 1213 and the second neck 1223 are detachably connected to the link body, respectively.

[0089] In the above implementation process, the first neck 1213 and the second neck 1223 are detachably connected to the connecting rod body, which facilitates the separate processing and manufacturing of each part of the intermediate connecting rod 120 during the manufacturing process, avoiding the complexity of mold opening during one-piece molding. At the same time, it also facilitates the replacement of parts.

[0090] Please refer to Figure 1 and Figure 2 In one alternative embodiment, the first connecting rod 110 includes one of a first connecting portion 1211 and a second connecting portion 1221. The tail connecting rod 130 includes the other of the first connecting portion 1211 and the second connecting portion 1221.

[0091] The first connecting rod 110 and the last connecting rod 130 are the connecting rods 100 at both ends of the connecting rod 100. Therefore, the first connecting rod 110 only needs to include one of the first connecting portion 1211 and the second connecting portion 1221, and the last connecting rod 130 only needs to include the other of the first connecting portion 1211 and the second connecting portion 1221. This allows for detachable assembly with the intermediate connecting rod 120.

[0092] In the above implementation process, a first connecting part 1211 and a second connecting part 1221 are respectively provided for the first connecting rod 110 and the tail connecting rod 130. This enables the first connecting rod 110 and the tail connecting rod 130 to be assembled with the intermediate connecting rod 120.

[0093] In one alternative embodiment, the materials used to make the first connecting rod 110, the intermediate connecting rod 120, and the tail connecting rod 130 include at least one of carbon fiber, glass fiber composite material, and aluminum alloy.

[0094] In the above process, carbon fiber, glass fiber composite material and aluminum alloy are high-strength and lightweight materials. Using at least one of them as the material for the first connecting rod 110, the intermediate connecting rod 120 and the tail connecting rod 130 improves the strength of the connecting rod 100 while reducing its weight.

[0095] Please refer to Figure 10 , Figure 10 This is a schematic diagram of the connecting rod 100 provided in this application embodiment adapted to the tent frame 300. In an optional embodiment, the connecting rod 100 is adapted to the tent frame 300. The tent frame 300 includes a first support gantry 310 and a second support gantry 320, both of which include a support rod 311 rotatably connected by a joint 200. The connecting rod 100 connects the first support gantry 310 and the second support gantry 320 by engaging with the joint 200.

[0096] The support rods 311 are rotatably connected to the gantry of the tent frame 300 via the joints 200. The gantry frames are connected to each other by the joints 200 of the connecting rods 100, so that the gantry frames are spaced at appropriate distances to form the tent frame 300. The connecting rods 100 connect the gantry frames to keep the distance between the gantry frames of the tent frame 300 stable during use, thereby improving the stability of the tent frame 300.

[0097] Furthermore, if the masts of the tent frame 300 are connected via scissor assemblies, a telescopic tent frame 300 is formed. Each mast has a locking mechanism; when the tent frame 300 is in the extended state, the locking mechanism locks the scissor assembly to maintain the extended state. The masts are connected via the joint of the connecting rod 100 with the key engagement of the mast. This further improves the stability of the tent frame 300.

[0098] In the above implementation process, when the connecting rod 100 is adapted to the tent frame 300, and when the connecting rod 100 connects to each frame, the tent frame 300 is extended at the corresponding distance and put into use. When the connecting rod 100 is removed from each frame, the first connecting rod 110, the middle connecting rod 120, and the tail connecting rod 130, which are detachably assembled together, can be disassembled, facilitating the storage of the connecting rod 100. Furthermore, the elastic connecting rope 140 of the connecting rod 100 connects the various parts of the connecting rod 100 together, preventing the loss of any component and avoiding confusion in the order of the various parts of the connecting rod 100. When the tent frame 300 is put back into use, there is no need to identify the individual parts to determine their assembly order; they can be directly assembled and connected to the various frames of the tent frame 300. By saving the assembly time of the connecting rod 100, the assembly time of the tent frame 300 is shortened.

[0099] The connecting rod 100 provided in this application achieves assembly and disassembly through the detachable connection between the first connecting rod 110, the intermediate connecting rod 120, and the tail connecting rod 130, facilitating the storage of the connecting rod 100. An elastic connecting rope 140 connects the first connecting rod 110, the intermediate connecting rod 120, and the tail connecting rod 130. When the connecting rod 100 is in a disassembled state where the first connecting rod 110, the intermediate connecting rod 120, and the tail connecting rod 130 are detached from each other, the loss of the components of the connecting rod 100 and the disorder of their sequence are prevented. The first connecting rod 110, the intermediate connecting rod 120, and the tail connecting rod 130 can be connected in series by a single elastic connecting rope 140, simplifying the manufacturing process. Multiple elastic connecting ropes 140 can also be used to connect them in series, either by connecting the ends of two of the first connecting rod 110, the middle connecting rod 120, and the tail connecting rod 130, thus saving material for making the elastic ropes. The anti-slip sinker 220 or flange 230 of the joint part 200 in the groove 210 of the joint member 200 at the joint part 100 improves the stability and reliability of the connection between the connecting rod 100 and the joint member 200.

[0100] Especially when the connecting rod 100 provided in this application is adapted to the tent frame 300, it not only improves the stability of the tent frame 300, but also facilitates the storage of the tent frame 300 after use and shortens the assembly time when the tent frame 300 is put back into use. The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
