[0030] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a foldable joint assembly 1, which includes a first joint 11 and a second joint 12, which are arranged at opposite ends of the joint assembly 1 in a first direction X for mounting a pipe 10. Specifically, the first joint 11 and the second joint 12 are respectively provided with a connecting portion 130, and the connecting portion 130 of the first joint 11 and the connecting portion 130 of the corresponding second joint 12 can be rotatably connected to form a connecting assembly 13 to switch the folding and unfolding state of the joint assembly 1. It can be understood that the first joint 11 and the second joint 12 are provided with a connecting portion 130 at one end in the first direction X, and the other end is used to mount the pipe 10, and the ends of the first joint 11 and the second joint 12 provided with the connecting portion 130 are rotatably connected together, and the pipes 10 mounted at both ends of the joint assembly 10 rotate together with the rotation of the first joint 11 and the second joint 12, and the folding and unfolding of the pipes are achieved by the folding and unfolding of the joint assembly 1.

[0031] Specifically, there are at least two connecting components 13 that are spaced apart. That is, the first joint 11 and the second joint 12 are rotatably connected together by at least two spaced apart connecting components 13. It can be understood that in the expanded state, the joint assembly 1 is prone to swing back and forth in a direction perpendicular to the first direction X. During the swinging process, the spaced apart connecting components 13 will squeeze each other. When the connecting component 13 on one side deforms and generates an extrusion force, the connecting component 13 on the other side will generate an opposite force to offset the extrusion force, preventing the connecting component 13 from further deforming, thereby preventing the joint assembly 13 from bending in the expanded state, so as to maintain the stability of the joint assembly 1 connecting the pipe 10, thereby making the overall bending deformation smaller and being able to better maintain basically on the same straight line.

[0032] The embodiment of the present invention provides a foldable joint assembly, which includes a first joint and a second joint, which are arranged at opposite ends of the joint assembly in a first direction for installing pipes. The first joint and the second joint are respectively provided with a connecting portion, and the connecting portion of the first joint and the connecting portion of the corresponding second joint can be rotatably connected to form a connecting assembly to switch the folding and unfolding states of the joint assembly, and the connecting assembly has at least two and is spaced apart. The embodiment of the present invention sets at least two connecting assemblies so that the first joint and the second joint can be rotatably connected together through the spaced-apart connecting assemblies, and the two pipes are connected together through the joint assembly. In the unfolded state, the two connecting assemblies can interact with each other to offset the extrusion force to keep the joint assembly straight, so that the pipe is not easy to bend at the folding part of the joint assembly after connection, and the stability and straight state of the connection of the joint assembly are maintained, thereby improving product quality and optimizing the user experience.

[0033] In some embodiments, as Figure 2As shown, the connecting assemblies 13 are spaced apart in a second direction Y, which is perpendicular to the first direction X, which is the longitudinal extension direction of the joint assembly 1. It is understood that two adjacent connecting assemblies 13 are arranged parallel to each other between the first joint 11 and the second joint 12, and that the two adjacent connecting assemblies 13 maintain a certain distance in the second direction Y. In the deployed state, the spacing between adjacent connecting assemblies 13 allows for deformation of the connecting assemblies 13 in the second direction Y, thereby generating sufficient mutual resistance between the adjacent connecting assemblies 13, keeping the pipe 10 straight in the deployed state and maintaining the stability of the connection at the joint assembly 1.

[0034] The embodiment of the utility model provides at least two spaced-apart connection components so that adjacent connection components can generate mutual resistance to prevent the joint component from bending in the unfolded state, thereby ensuring the stability of the connection of the joint component. After unfolding, the joint component can still be stably maintained in a straight state, thereby improving the user experience.

[0035] In some embodiments, as Figure 1 and Figure 2 As shown, each connecting portion 130 includes two protrusions 131 spaced apart in the second direction Y. Specifically, the protrusions 131 on the first joint 11 and the second joint 12 are alternately arranged in the second direction Y, so that after they are rotated and connected with each other, they can guide the rotation path of the first joint 11 and the second joint 12. It can be understood that the connecting portion 130 has protrusions 131 alternately arranged with each other, and after the first joint 11 and the second joint 12 are connected, the protrusions 131 on the first joint 11 and the protrusions 131 on the second joint 12 are interlaced and connected together. During the rotation of the joint assembly 1, the first joint 11 and the second joint 12 rotate along the gap between adjacent protrusions 131. In other words, the gap between two adjacent protrusions 131 guides the rotation path of the first joint 11 and the second joint 12, so that the joint assembly 1 remains stable during the rotation process.

[0036] The embodiment of the utility model guides the path of the first joint and the second joint during rotation by alternately arranging protrusions on the first joint and the second joint, and multiple protrusions are respectively provided, and the multiple protrusions are cross-connected, so the structural strength is high, so that the joint assembly remains stable during rotation, thereby improving the quality of the product.

[0037] In some embodiments, as Figure 3As shown, the connecting portion 130 further includes a rotating shaft 133. The protruding member 131 has a through hole 132, and the rotating shaft 133 is inserted into the through hole 132 to connect with the protruding member 131. In other words, the protruding member 131 has corresponding through holes 132. After the protruding member 131 on the first connector 11 and the protruding member 131 on the second connector 12 are interlaced, the rotating shaft 133 passes through the through holes 132, connecting the first connector 11 and the second connector 12 together via the protruding member 131, allowing the first connector 11 and the second connector 12 to rotate about the rotating shaft 133.

[0038] In the embodiment of the utility model, the rotating shaft passes through the through hole set on the protrusion. Only one additional part needs to be installed to achieve the rotatable connection between the first joint and the second joint, which simplifies the structure of the joint assembly, facilitates installation and maintenance, and helps to reduce production costs.

[0039] In some embodiments, as Figure 3 As shown, the joint assembly 1 further includes a first positioning member 141 and a second positioning member 142. Specifically, the first positioning member is located on one of the first joint and the second joint, and the second positioning member is located on the other of the first joint and the second joint. Figure 4 As shown, in the expanded state, the first positioning member 141 and the second positioning member 142 cooperate to fix the rotation angle of the first joint 141 and the second joint 142. It can be understood that the first positioning member 141 and the second positioning member 142 are provided at the connection between the first joint 11 and the second joint 12. Specifically, when the first positioning member 141 is provided on the first joint 11, the second positioning member 142 is provided on the second joint 12; when the first positioning member 141 is provided on the second joint 12, the second positioning member 142 is provided on the first joint 11. In the expanded state, the first positioning member 141 and the second positioning member 142 can cooperate with each other to limit the joint assembly 11 from continuing to rotate, thereby preventing the joint assembly 11 from rotating at an excessively large angle, which makes it difficult to fix the joint assembly 1 in the expanded state.

[0040] The embodiment of the utility model provides a first positioning member and a second positioning member so that the first positioning member and the second positioning member can cooperate with each other to limit the rotation angle of the joint assembly, stably fix the joint assembly in the expanded state, keep the pipe straight, improve product quality, and optimize the product usage experience.

[0041] In some embodiments, as Figure 3 and 4As shown, the first positioning member 141 is a groove structure, and the second positioning member 142 is a protrusion structure. In the expanded state, the second positioning member 142 is at least partially located in the first positioning member 141. That is to say, the structure of the first positioning member 141 is a groove structure, and the structure of the second positioning member 142 is a protrusion structure. For example, when the groove structure is provided on the first joint 11, and the protrusion structure is provided on the second joint 12, when the connection assembly 1 is in the expanded state, the protrusion structure extends into the groove structure, realizing the cooperation between the first positioning member 141 and the second positioning member 142, restricting the second joint 12 from continuing to rotate, so that the joint assembly 1 can be stably maintained in the expanded state and kept straight. A plurality of protrusion structures are arranged at intervals along the second direction Y, and the number of grooves of the groove structure corresponds to the number of protrusions of the protrusion structure, so as to achieve stable cooperation.

[0042] It is understandable that the groove structure can also be provided on the second joint 12, and the protrusion structure can also be provided on the first joint 11. As long as the groove structure and the protrusion structure can be matched and positioned, no further limitation is made here.

[0043] The embodiment of the utility model realizes the positioning of the joint assembly through a simple structural setting by setting the first positioning member and the second positioning member to cooperate with a groove structure and a protrusion structure, thereby ensuring the stability of the joint assembly in the expanded state while simplifying the structure, optimizing the quality of the product, and facilitating production and manufacturing.

[0044] In some other embodiments, such as Figure 5 As shown, the first positioning member 141 and the second positioning member 142 can also be arranged in a stepped structure relative to each other. Specifically, the outer contours of the first positioning member 141 and the second positioning member 142 at their relative positions correspond to each other. It is understood that the first positioning member 141 and the second positioning member 142 can also be arranged in a stepped structure with matching outer contours. The contacting stepped surface of the first positioning member 141 and the second positioning member 142 restricts further rotation of the second connector 12 after rotating to the expanded state, thereby maintaining a straight line for the connected pipes.

[0045] The embodiment of the utility model arranges the first positioning member and the second positioning member as a step structure whose outer contours match each other, and realizes the positioning of the joint assembly through the contact and abutment of the step surfaces, thereby ensuring the stability of the connection of the joint assembly and simplifying the structure for easy production and processing.

[0046] In addition, it should be noted that the first positioning member and the second positioning member may also be other structures capable of cooperative positioning, and no further limitation is imposed herein.

[0047] In some embodiments, as Figure 6As shown, the first connector 11 has a first mounting groove 110, and the second connector 12 has a second mounting groove 120. In the longitudinal extension direction of the connector assembly 1, the first mounting groove 110 is located on the end of the first connector 11 away from the connecting portion 130, and the second mounting groove 120 is located on the end of the second connector 12 away from the connecting portion 130. The first mounting groove 110 and the second mounting groove 120 are used to insert and receive the pipe 10. It is understood that the first mounting groove 110 and the second mounting groove 120 are provided at opposite ends of the connector assembly 1 in the first direction X, with the first mounting groove 110 located on the first connector 11 and the second mounting groove 120 located on the second connector 12. The two pipes 10 are installed in the first mounting groove 110 and the second mounting groove 120, respectively, by insertion. The pipes 10 and the first mounting groove 110 and the second mounting groove 120 form an interference fit. The pipes 10 can be folded together by simple insertion, making installation simple and easy to operate.

[0048] The embodiment of the utility model provides a first installation groove and a second installation groove on the joint assembly, so that the pipe can be installed by simple insertion, making the pipe foldable, simple to operate, and easy to install, which brings great convenience to users.

[0049] In some embodiments, as Figure 3 and Figure 7 As shown, the rotating shaft 133 includes a deformable portion 1331 and a fixing portion 1332. The deformable portion 1331 is provided at one end of the rotating shaft 133, and the fixing portion 1332 is provided at both ends of the rotating shaft 133 in the longitudinal direction. The deformable portion 1331 has a deformation groove 13310 extending through the rotating shaft 133 in the diametrical direction. The rotating shaft 133 is inserted into the through hole 132. The fixing portion 1332 is wider than the diameter of the through hole 132 to fix the position of the rotating shaft 133 in the through hole 132. It can be understood that a deformation portion 1331 is provided at one end of the rotating shaft 133, and a deformation groove 13310 is provided on the deformation portion 1331. The deformation groove 13310 is arranged to pass through the diameter direction of the rotating shaft 133. Under the action of external force, the deformation portion 1331 is squeezed and deformed toward the inside of the deformation groove 13310. At this time, the width of the deformation portion 1331 is smaller than the diameter of the through hole 132, and the rotating shaft 133 can be smoothly inserted into the through hole 132. When the external force is removed, the deformation portion 1331 resumes its deformation and stably cooperates with the through hole 132, thereby rotatably connecting the first joint 11 and the second joint 12 together.

[0050] At the same time, fixing portions 1332 with a width greater than the diameter of the through hole 132 are provided at both ends of the rotating shaft 133. The fixing portions 1332 are located on the outside of the through hole 132, limiting the rotating shaft 133 in the length direction of the rotating shaft 133, and further fixing the rotatable connection between the first joint 11 and the second joint 12.

[0051] The embodiment of the utility model provides a deformation portion and a fixing portion on the rotating shaft, which facilitates the installation of the rotating shaft while preventing the rotatable shaft from moving in the length direction, thereby ensuring the stability of the connection between the rotating shaft and the through hole and optimizing the performance of the product.

[0052] In some embodiments, the first joint 11 and / or the second joint 12 can rotate in an angle range of 0 to 180 degrees. Figure 3 As shown, the first joint 11 and the second joint 12 are rotated to a state parallel to each other in the folded state, thereby achieving complete folding of the pipe for easy storage and transportation; Figure 2 As shown, the first joint 11 and the second joint 12 are in the unfolded state, and the first joint 11 and the second joint 12 are located on the same straight line, so that the pipes connected at both ends of the joint assembly 1 are fully unfolded, which is convenient for users to use. That is, the rotation range of the first joint 11 and the second joint 12 is 0 to 180 degrees to achieve complete folding and unfolding of the pipe.

[0053] The embodiment of the present invention limits the rotation range of the first joint and the second joint, so that the pipes installed at both ends of the joint assembly can be completely folded and unfolded. In the folded state, the pipes can be folded in half, reducing the space occupied by the pipes, making it easier for users to carry and transport them outside; in the unfolded state, the pipes at both ends of the joint assembly remain in the same straight line, so that the pipes can remain straight even after unfolding, further optimizing the function of the product, improving product quality, and improving the user experience.

[0054] The present invention also provides a tennis net, comprising a joint assembly 1, a net body, and a tubular body. Specifically, a plurality of tubular bodies are provided, each connected via a joint assembly to form a tennis net frame, with the net body being connected to at least one of the tubular bodies. In other words, the plurality of tubular bodies are foldably connected together via the joint assembly 1 to form a foldable tennis net frame, with the net body being connected to the net frame to form a foldable tennis net. When the user needs to use the tennis net, the net frame can be unfolded and the net body can be propped up for use. When the user no longer needs to use the tennis net, the net frame can be folded back up and stored for easy transportation and portability.

[0055] The embodiment of the utility model enables the joint assembly to connect multiple tubes to form a foldable earth net frame. The folded ball net is small in size and easy to store and transport. When the user needs to use it, the ball net frame can be unfolded for use. The operation is simple, which optimizes the user experience.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
