Using ordinary coupling devices such as bolts, nuts, etc. fasteners, although they can achieve basic connection functions, often have the following technical problems:

[0003] Device, equipment needs to rotate synchronously: due to the immovability and non-rotatability of the wall or device, when using ordinary coupling devices, if the device, equipment itself needs to have certain rotating flexibility, the traditional coupling method cannot meet this demand. This may cause the device, equipment to not work normally after installation, or to be damaged during use due to limited rotation.

[0004] Connection instability: ordinary coupling devices often cannot provide sufficient stability and reliability, especially when bearing large loads or long-term use. Instability of connection may cause loosening or falling of the device, equipment, and thus cause safety hazards.

[0005] Difficult installation: traditional coupling methods often require complex operation steps and accurate measurements during installation to ensure the accuracy and stability of the connection. This not only increases the difficulty and cost of installation, but also may prolong the installation period.

[0042] Hereinafter, the present application will be further described based on the preferred embodiments and with reference to the accompanying drawings.

[0043] The words in the present specification are used for describing the embodiments of the present application, but are not intended to limit the present application. Unless explicitly defined and limited, if the terms "arranged", "connected", "linked" appear, they should be interpreted broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be mechanically connected, can be directly connected, or indirectly connected through an intermediate medium, can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be specifically understood.

[0044] In addition, in the description of the embodiments of the present application, various components on the drawings are enlarged or reduced for the convenience of understanding, but this practice is not intended to limit the protection scope of the present application.

[0045] The present application provides an articulating device 1 for connecting a first device and a second device, the first device being a wall surface or device that cannot be rotated or moved, and the second device being a structure or device to be installed on the surface of the first device, so that flexible connection between the device, equipment and the wall surface or device can be achieved, the stability and reliability of the connection can be improved, and the installation process can be simplified.

[0046] The structure of the articulating device 1 in the present application will be described in detail below,Figure 1 and Figure 2 respectively show the overall structure diagram and the exploded view of the articulated device 1 in the present application, as Figure 1 and Figure 2 shown, the articulated device 1 comprises a positioning structure 11, a fastener 15, and an inner sleeve structure 12, a limiting structure 13 and a matching structure 14 connected in turn along the axis direction of the articulated device 1, the matching structure 14 extends into the positioning structure 11, the fastener 15 is sleeved on the outer periphery of the matching structure 14 and is clamped between the matching structure 14 and the positioning structure 11, and the bottom end of the limiting structure 13 abuts against the top end of the positioning structure 11; wherein the inner sleeve structure 12 extends into the first device and is threadedly connected with the first device, the positioning structure 11 is threadedly connected with the second device, and the inner sleeve structure 12 and the positioning structure 11 can rotate independently. In the present application, the inner sleeve structure 12 can be connected or separated with the first device during rotation; at the same time, through the cooperation of the limiting structure 13, the matching structure 14, the fastener 15 and the positioning structure 11, a stable connection is established between the inner sleeve structure 12 and the first device, and at the same time a stable connection is also established between the positioning structure 11 and the second device. In particular, the circumferential rotation between the positioning structure 11 and the inner sleeve structure 12 does not interfere with each other, ensuring that the positioning structure 11 and the second device can remain stationary and not rotate when the inner sleeve structure 12, the limiting structure 13 and the matching structure 14 rotate, and by the same token, the inner sleeve structure 12 also does not rotate when the positioning structure 11 rotates. This design not only realizes the flexible connection between the first device and the second device, but also guarantees the stability and reliability of the connection. More importantly, it greatly simplifies the installation process and improves work efficiency. Through such a delicate structure design, the present application successfully solves the complexity and instability problems that may exist in the traditional connection method.

[0047] Further, as Figure 5 shown, to realize the connection of the inner sleeve structure 12 and the first device, the inner sleeve structure 12 is provided with a first through hole penetrating along its axis direction, the shape of the first through hole is matched with the first fastening tool, and the first fastening tool drives the inner sleeve structure 12 to rotate through the first through hole, thereby realizing the connection or separation of the inner sleeve structure 12 and the first device.

[0048] In some specific embodiments of the present application, the cross section of the first through hole is hexagonal, and the first fastening tool can adopt a universal wrench, which makes the operation more convenient in limited space and has better adaptability with the universal wrench. It can be imagined that the cross section of the first through hole can also be triangular, quadrilateral and other polygonal shapes, or other shapes such as elliptical shape, and the first fastening tool only needs to adopt a tool matched with the shape of the through hole.

[0049] Further, as Figure 1 and Figure 2As shown, the inner sleeve structure 12 has an external thread on its outer periphery, and the first device has an internal thread that mates with this external thread. When the first fastening tool drives the inner sleeve structure 12 to rotate through the first through hole, the external thread of the inner sleeve structure 12 will rotate synchronously relative to the internal thread component of the first device. This rotational motion allows the inner sleeve structure 12 and the first device to be connected or separated by a threaded connection. Specifically, if the rotation direction is the tightening direction, the inner sleeve structure 12 and the first device will tighten further and further, achieving a connection; conversely, if the rotation direction is the loosening direction, they will gradually separate.

[0050] Furthermore, the positioning structure 11 has an internal thread on its inner circumference, and the second device has an external thread that mates with this internal thread. When the second fastening tool drives the positioning structure 11 to rotate via its outer circumference, the internal thread of the positioning structure 11 rotates synchronously relative to the external thread of the second device. This rotational motion allows the positioning structure 11 and the second device to connect or separate via a threaded connection. Specifically, if the rotation direction is the tightening direction, the positioning structure 11 and the second device will tighten further, achieving a connection; conversely, if the rotation direction is the loosening direction, they will gradually separate.

[0051] In some preferred embodiments of this application, the hinge device 1 is not only versatile but also suitable for connecting water pipe fittings. In water systems, to prevent leakage—a critical issue—the hinge device 1 is designed with a tight sealing mechanism and a reliable connection structure. For example... Figure 2 As shown, the hinge device 1 also includes a sealing structure 16. A second limiting groove 121 is formed on the outer periphery of the inner sleeve structure 12. The sealing structure 16 is housed within the second limiting groove 121, and the inner sleeve structure 12 is sealed to the first device via the sealing structure 16. Through precisely matched threads, sealing gaskets, or other advanced sealing technologies, the tightness of the connection is ensured, effectively preventing liquid leakage. This design not only improves the safety and stability of the water system but also significantly extends the system's service life, providing users with a more reassuring and convenient user experience.

[0052] In some specific embodiments of this application, such as Figure 2 and Figure 7As shown, the fastener 15 is a C-shaped clamp structure, and the cooperating structure 14 is provided with a first limiting clamping groove 141 on the outer periphery, the fastener 15 is accommodated in the first limiting clamping groove 141, and the top end thereof is in abutment with the top end of the first limiting clamping groove 141 and the positioning structure 11. The cooperating structure 14 realizes the limiting of the fastener 15 in the axial direction of the hinge device 1 through the first limiting clamping groove 141. At the same time, the cooperating structure 14 realizes the limiting of the positioning structure 11 in the axial direction through the contact with the first limiting clamping groove 141 and the positioning structure 11, thereby ensuring the limiting of the second device in the axial direction. In this way, the positioning stability of the second device and the positioning structure 11 is ensured during the rotation of the cooperating structure 14.

[0053] In some specific embodiments of the present application, as shown in Figure 3 and Figure 4 As shown, the outer periphery of the positioning structure 11 is designed in a hexagonal shape, and the second fastening tool drives the positioning structure 11 to move circumferentially relative to the second device through the cooperating connection with the outer periphery.

[0054] Especially important is that when the inner sleeve structure 12 rotates, the positioning structure 11 and the second device can remain in a relatively static state due to the close cooperation between the positioning structure 11 and the second device. This means that although the inner sleeve structure 12 is constantly rotating, the positioning structure 11 and the second device fixed thereby can maintain their original position and posture and will not rotate unnecessarily.

[0055] In summary, the design of the hexagonal positioning structure not only enhances the stability and reliability of the structure, but also provides a strong guarantee for the smooth operation of the entire system, simplifies the structure while ensuring stability and reliability.

[0056] It can be imagined that the positioning structure 11 can also be designed in a triangular, quadrilateral, or other polygonal shape, or an elliptical, star-shaped, or other regular or irregular shape, or through the setting of a limiting piece to ensure the synchronization of the positioning structure 11 and the second device.

[0057] Further, when the fastener 15 is a C-shaped clamp structure, and in order to ensure the stability of the limiting, the clamp spring is generally made of metal material, and a larger force is required to open the clamp spring and place it in the first limiting clamping groove 141 when it is accommodated in the first limiting clamping groove 141, which causes the problem of difficult installation. Based on this problem, as shown in Figure 2As shown, the matching structure 14 is specially designed with a slope expansion structure 142, the minimum outer diameter of which is smaller than that of the fastener 15. The structure is located at the bottom end of the matching structure 14, and its longitudinal section is a slope structure with the slope facing away from the limiting structure 13, meaning that the outer diameter of the slope expansion structure 142 gradually decreases in the direction away from the limiting structure 13. When the fastener 15 (i.e. the C-shaped spring) moves in the direction close to the limiting structure 13, its inside is gradually expanded due to the slope expansion structure 142, until it moves to the position of the first limiting slot 141, the fastener 15 can be automatically and smoothly accommodated in the first limiting slot 141, thereby greatly simplifying the installation process and improving the installation efficiency.

[0058] Further, in order to facilitate the smooth displacement of the fastener 15 along the axis direction of the articulated device 1 into the first slot 141 and clamped between the matching structure 14 and the positioning structure 11, the application also provides an installation assembly 2, Figures 5-7 respectively show the overall structure diagram, the exploded view and the cross-sectional view of the installation assembly 2 and the articulated device 1 in the application, as Figures 5-7 shown, the installation assembly 2 and the articulated device 1 are coaxially arranged, and the end thereof facing the articulated device 1 abuts against the fastener 15 and can push the fastener 15 to displace through the slope expansion structure 142 and be smoothly accommodated in the first limiting slot 141.

[0059] Further, the installation assembly 2 includes a fixed structure 21 and a pushing structure 22, the fixed structure 21 extends into the articulated device 1 and abuts against the articulated device 1 in a limiting and movable manner, and the pushing structure 22 is sleeved on the outer periphery of the fixed structure 21 and the end thereof facing the articulated device 1 can abut against the fastener 15 and push the fastener 15 to move along the axis direction of the installation assembly 2. The fixed structure 21 is used to fix the articulated device 1 to achieve the position of the articulated device 1 and the first device, and the pushing structure 22 is used to push the fastener 15 to smoothly accommodate in the first limiting slot 141 through the slope expansion structure 142.

[0060] Further, Figure 9 and Figure 10 respectively show the overall structure diagram and the cross-sectional view of the pushing structure 22 in the application, as Figure 9 and Figure 10As shown, the push structure 22 is provided with a through hole penetrating along the axial direction thereof, which is used to accommodate the fixing structure 21 and provide guidance for the displacement of the push structure 22 based on the fixing structure 21, so as to ensure that the fixing structure 21 can stably exist inside the push structure 22; the push structure 22 comprises a push part 221 and an accommodation part 222 connected in sequence along the axial direction thereof, the inner diameter of the push part 221 is greater than that of the accommodation part 221, and the push part 221 and the accommodation part 222 are transitioned through a limiting end face 223, which is arranged towards the articulated device 1. The push part 221 moves synchronously with the accommodation part 222, the push part 221 acts on the fastener 15, and the limiting end face 223 is limitedly abutted with the fixing structure 21, so as to avoid the axial displacement of the fixing structure 21 in the direction away from the articulated device 1, so as to further ensure the stability of the position of the articulated device 1 and the first device.

[0061] In some preferred embodiments of the present application, in the face of the challenge brought by the complex shape of the slope expansion structure 142 to the design of the push structure 22, especially the need for high-precision machining of the through hole to adapt to such shape, we propose an innovative solution. In order to avoid the problem of high machining precision, the push structure 22 is designed to further comprise an abutting piece 224. The abutting piece 224 is cleverly sleeved on the outer periphery of the cooperating structure 14, one end of which is in close abutment with the push part 221, and the other end is directly in contact with the fastener 15.

[0062] This design makes the push structure 22 not need to adapt to the slope expansion structure 142 through a complex through hole shape, but through the intermediate medium of the abutting piece 224 to transfer the force. The abutting piece 224 can smoothly transmit the pushing force of the push part 221 to the fastener 15, and use the expansion effect of the slope expansion structure 142 to easily push the fastener 15 into the first limiting clamping groove 141.

[0063] In this way, we not only simplify the design of the push structure 22 and reduce its machining precision requirement, but also improve the efficiency and reliability of the entire installation process. The introduction of the abutting piece 224 is a clever and effective innovation of the present application in solving the problem of complex structure cooperation.

[0064] In some preferred embodiments of the present application, the abutting piece 224 is at least one C-shaped circlip, the number of which is determined based on the length of the slope expansion structure 142 along the axial direction thereof, which has the advantages of flexibility, simplicity, and reliable pushing.

[0065] Further, Figure 8 The overall structure diagram of the fixing structure 21 in the present application is shown, which comprises a fixing part 211 and a limiting part 212 connected in sequence along the axial direction thereof, the fixing part 211 is provided with a through hole penetrating along the axial direction thereof, which is used to accommodate the cooperating structure 14 and provide guidance for the displacement of the fixing structure 21 based on the cooperating structure 14, so as to ensure that the cooperating structure 14 can stably exist inside the fixing structure 21; the fixing part 211 and the limiting part 212 are transitioned through a limiting end face 213, which is arranged towards the articulated device 1. Figure 8 and Figure 7As shown, the fixing structure 21 includes an insertion part 211, a limiting part 212 and an extension part 213 connected in sequence along the axial direction, the outer diameter of the insertion part 211 and the extension part 213 is smaller than that of the limiting part 212, the insertion part 211 extends into the articulated device 1, the limiting part 212 abuts against one end of the cooperating structure 14 and the other end abuts against the limiting end face 223. Among them, the outer diameter of the insertion part 211 is relatively small, which can easily extend into the interior of the articulated device 1, as a guide part for the fixing structure 21 to enter the articulated device 1, and prepares for the subsequent fixing operation; the limiting part 212 forms a obvious step or flange, which not only ensures the firm connection between the fixing structure 21 and the articulated device 1, but also ensures the accurate positioning of the pushing structure 22 when moving and limits its movement range, thereby increasing the stability and reliability of the whole structure; the extension part 213 provides additional structural support for the whole fixing structure 21, and can further fix or connect other parts. In summary, the fixing structure 21 in the present application realizes the effective fixing of the articulated device 1 through its unique three-section design, and also ensures the accurate positioning and limitation of the pushing structure 22 when moving, thereby improving the stability and reliability of the whole system.

[0066] In summary, the detailed assembly process of the articulated device 1 and the mounting assembly 2 thereof in the present application is as follows:

[0067] First, the inner sleeve structure 12 of the articulated device 1 is partially inserted into the inner thread of the first device, preparing for the subsequent connection. Then, the inner sleeve structure 12 is rotated by using the first fastening tool, so that it is tightly connected with the first device through threads.

[0068] Subsequently, the top end of the positioning structure 11 is accurately abutted against the bottom end of the limiting structure 13, ensuring that the positional relationship between the two is correct.

[0069] Next, the fastener 15 (such as a C-shaped clamp spring) and the abutting piece 224 are sequentially sleeved on the slope expansion structure 142 of the cooperating structure 14. This step is to use the special shape of the slope expansion structure 142 to prepare for the smooth installation of the fastener 15.

[0070] Then, the fixing structure 21 is inserted into the interior of the articulated device 1, ensuring that the insertion part 211 of the fixing structure 21 smoothly enters, while the limiting part 212 abuts against one end of the cooperating structure 14 and the limiting end face 223 of the pushing structure 22, providing support for the subsequent positioning and fixing.

[0071] At this time, the pushing part 221 and the containing part 222 of the pushing structure 22 are sleeved outside the fixed structure 21, and a pushing force is applied to make the fastener 15 and the abutting part 224 move along the slope expansion structure 142. With the movement of the fastener 15, it is gradually expanded until it is smoothly inserted and clamped in the first limiting clamping groove 141, and the fixing is completed.

[0072] After the above steps are completed, the fixed structure 21 and the pushing structure 22 can be removed from the articulated device 1, at which time the articulated device 1 has been firmly fixed to the fitting structure 14 by the fastener 15.

[0073] Finally, the second device is screw-connected with the positioning structure 11 by the second fastening tool, ensuring that the inner sleeve structure 12 and the first device remain relatively stationary during the rotation of the positioning structure 11.

[0074] The entire assembly process is designed ingeniously and the steps are clear, ensuring that the articulated device 1 and its installation assembly 2 can be efficiently and accurately assembled together to meet the needs of various application scenarios.

[0075] The specific embodiments of the present application are described in detail above, and for those skilled in the art, without departing from the principles of the present application, some improvements and modifications can be made to the present application, and these improvements and modifications also belong to the protection scope of the present application.
