[0048] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all the other embodiments obtained by a person skilled in the art without creative labor are within the protection scope of the present application.

[0049] In this document, reference to“an embodiment” or“the embodiments” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. A person skilled in the art will understand that an embodiment described herein can be incorporated in other embodiments.

[0050] The embodiment of the present application provides a joint assembly for a faucet, which is convenient to install and can avoid damage of the assembly caused by assembly actions.

[0051] Please refer to Figures 1 to 4 The joint assembly comprises a first joint 10 and a second joint 20, wherein Figure 1 and Figure 2 The up-down direction shown in the drawing is the length direction.

[0052] The first joint 10 comprises a first channel 100 extending through the length direction of the first joint 10, a first connecting part 11, and a first guide structure 12 and a first connecting structure 13 arranged on the first connecting part 11. The second joint 20 comprises a second channel 200 extending through the length direction of the second joint 20, a second connecting part 21, and a second guide structure 22 and a second connecting structure 23 arranged on the second connecting part 21. The second connecting part 21 is arranged to be sleeved on the first connecting part 11 to realize the mutual sleeving of the second connecting part 21 and the first connecting part 11. During the mutual sleeving of the second connecting part 21 and the first connecting part 11, the first guide structure 12 and the second guide structure 22 can guide each other to limit the movement direction of the first connecting part 11 and the second connecting part 21, so as to align the first connecting structure 13 with the second connecting structure 23 during the sleeving process. After the first connecting part 11 and the second connecting part 21 are sleeved, the first connecting structure 13 and the second connecting structure 23 are matched to fix the relative position of the first connecting part 11 and the second connecting part 21 after being sleeved.

[0053] For example, in one embodiment of the present application, the first guide structure 12 and the second guide structure 22 guide the relative rotation of the first connecting part 11 and the second connecting part 21, so as to limit and adjust the movement direction of the first connecting part 11 and the second connecting part 21 during the sleeving process. Therefore, the first connecting structure 13 and the second connecting structure 23, which are not aligned, can be rotated and aligned during the sleeving process of the first connecting part 11 and the second connecting part 21, so as to facilitate the matching of the first connecting structure 13 and the second connecting structure 23.

[0054] The joint assembly in the embodiment of the present application can limit the movement direction of the first connecting part 11 and the second connecting part 21 through the mutual matching of the first guide structure 12 and the second guide structure 22 during the sleeving process, so as to automatically realize the alignment of the first connecting structure 13 and the second connecting structure 23 during the execution of the assembling action. The first connecting structure 13 and the second connecting structure 23 are matched to fix the relative position of the first connecting part 11 and the second connecting part 21 after being sleeved, without the need for artificial alignment of the first connecting structure 13 and the second connecting structure 23 in advance. The installation is convenient, and the damage of the assembly caused by the non-prealignment can be avoided.

[0055] For example, please refer to Figures 5 to 9The first guide structure 12 comprises two guides 120 which are arranged on the outer wall of the first joint part 11 at intervals along the length direction of the first joint part 10; the second guide structure 22 comprises two guide plates 220 which are arranged on the inner wall 210 of the second joint part 21 at intervals along the length direction of the second joint part 20, and a guide groove 2200 is formed between two adjacent guide plates 220, and each guide groove 2200 corresponds to a guide 120. During the process of sleeving the second joint part 21 on the first joint part 11, each guide 120 can be accommodated in and slide in the corresponding guide groove 2200.

[0056] For example, each guide 120 comprises two first guide walls 121 which intersect at one end of the guide 120 and form a first guide tip 122, and each guide plate 220 comprises two second guide walls 221 which intersect at one end of the guide plate 220 and form a second guide tip 222. During the process of sleeving the second joint part 21 on the first joint part 11, the first guide tip 122 faces the second joint part 21, the second guide tip 222 faces the first joint part 11, and the first guide wall 121 is located in the guide groove 2200 and slides against at least one second guide wall 221 of the two adjacent guide plates 220. During the process of sliding the first guide wall 121 against the second guide wall 221, the second joint part 21 and the first joint part 11 will rotate relative to each other, so that the first connecting structure 13 is aligned with the second connecting structure 23 during the sleeving process by the cooperation of the first guide structure 12 and the second guide structure 22, so as to facilitate the cooperation and fixation of the first connecting structure 13 and the second connecting structure 23.

[0057] Optionally, in an embodiment, the two first guide walls 121 and the first guide tip 122 in each guide 120 form an isosceles triangle top corner structure, that is, the two first guide walls 121 have the same length, opposite inclination directions but the same inclination angle, so as to form a bilateral symmetry structure in the circumferential direction of the first joint part 11; similarly, the two second guide walls 221 and the second guide tip 222 in each guide plate 220 form an isosceles triangle top corner structure, that is, the two second guide walls 221 have the same length, opposite inclination directions but the same inclination angle, so as to form a bilateral symmetry structure in the circumferential direction of the second joint part 21. This design not only makes the structure processing more convenient, but also enables the first guide wall 121 to produce the same force effect and movement restriction effect when cooperating with different second guide walls 221, and ensures that the same alignment effect can be produced when sleeving the first joint part 11 and the second joint part 21 from different angles.

[0058] It is easy to understand that in other embodiments of the present application, the first guide tip 122 and the second guide tip 222 can also be made as arc surfaces, when the two arc surfaces abut against each other, the first guide wall 121 and the second guide wall 221 on the two sides of the arc surfaces are designed to be inclined, so that the first guide wall 121 slides along the second guide wall 221, thereby causing the relative rotation between the second connecting part 21 and the first connecting part 11 during the relative sliding of the first guide wall 121 along the second guide wall 221, so as to align the first connecting structure 13 with the second connecting structure 23 in the sleeving process by the cooperation of the first guide structure 12 and the second guide structure 22, so as to facilitate the cooperation and fixation of the first connecting structure 13 and the second connecting structure 23.

[0059] In addition, the first guide structure 12 and the first connecting structure 13 can be manufactured respectively and then assembled and fixed as a whole, or can be directly integrally manufactured as a whole. For example, in the embodiments of the present application, the first guide structure 12 and the first connecting structure 13 are integrally manufactured as a whole, that is, the first guide structure 12 and the first connecting structure 13 are integrally arranged.

[0060] In a feasible embodiment of the present application, the first guide structure 12 and the first connecting structure 13 are connected to each other, and the first guide structure 12 and the first connecting structure 13 can rotate on the outer wall of the first connecting part 11, so that when the installation space is limited or needs to be maintained, the relative rotation between the first guide structure 12, the first connecting structure 13 fixedly connected to the second connecting part 21 and the first connecting part 11 can make the operator operate more conveniently, and the relative rotation design scheme can also reduce the stress of the connecting part caused by water flow impact or external force, thereby extending the service life of the joint assembly.

[0061] Further, for example, in the embodiments of the present application, the first joint 10 further comprises a first rotating structure 14, the first rotating structure 14 is arranged on the outer wall of the first connecting part 11, and the first rotating structure 14 can rotate on the outer wall of the first connecting part 11; the first guide structure 12 and the first connecting structure 13 are arranged on the first rotating structure 14, and the first guide structure 12 is closer to the free end of the first connecting part 11 than the first connecting structure 13. Further, the first rotating structure 14 is a sleeve ring sleeved on the outer wall of the first connecting part 11, the first connecting structure 13 extends from the sleeve ring towards the second connecting part 21, and the first guide structure 12 extends from the end of the first connecting structure 13 towards the second connecting part 21.

[0062] The first guide structure 12, the first connecting structure 13 and the first rotating structure 14 can be manufactured respectively and then assembled and fixed as a whole, or can be directly integrally manufactured as a whole. For example, in the embodiment of the present application, the first guide structure 12, the first connecting structure 13 and the first rotating structure 14 are integrally manufactured as a whole, that is, the first guide structure 12, the first connecting structure 13 and the first rotating structure 14 are integrally arranged.

[0063] For the first rotating structure 14, the sleeve ring can be an O-shaped ring or a C-shaped ring. When the first rotating structure 14 is a C-shaped ring, it can be deformed under external force to make the opening wider, thereby facilitating the operator to disassemble it from the first combining part 11. In this way, when the first guide structure 12 and / or the first connecting structure 13 are damaged, the first rotating structure 14 can be removed and replaced, and the operation process is simple and fast.

[0064] It should be noted that, in one feasible embodiment of the present application, one of the first connecting structure 13 and the second connecting structure 23 comprises a coupling part, and the other comprises a clamping hole or a clamping groove for accommodating the coupling part to fix the relative position of the first combining part 11 and the second combining part 21 after they are sleeved with each other.

[0065] For example, please continue to refer to Figure 5 and Figure 6 The first connecting structure 13 comprises a coupling part 130 and a limiting part 131 connected with the coupling part 130, the limiting part 131 is recessed inwardly (that is, towards the direction close to the central axis of the first combining part 11) from the end of the coupling part 130, the second connecting structure 23 comprises a clamping hole 24 arranged on the inner wall of the second combining part 21, after the first combining part 11 and the second combining part 21 are sleeved with each other, the clamping hole 24 is used to accommodate the coupling part 130, and the limiting part 131 is used to abut against the inner wall 210 of the second combining part 21 to limit the first connecting structure 13 from being completely accommodated in the clamping hole 24, thereby realizing the cooperative connection of the first connecting structure 13 and the second connecting structure 23. The clamping hole 24 penetrates through part of the side wall of the second combining part 21.

[0066] It is not difficult to understand that the clamping hole 24 can also be arranged as a clamping groove, as long as it can accommodate the coupling part 130 and realize the cooperative connection of the first connecting structure 13 and the second connecting structure 23.

[0067] Further, one of the first joint 10 and the second joint 20 of the embodiment of the present application can further comprise an operating structure 25 for driving the first connecting structure 13 or the second connecting structure 23 to be deformed to release the connection relationship between the first connecting structure 13 and the second connecting structure 23.

[0068] For example, in one example embodiment of the present application, the first connecting structure 13 comprises a coupling portion 130 connected with the first guiding structure 12, the second connecting structure 23 comprises a clamping hole 24 arranged on the second connecting portion 21, the clamping hole 24 is used to accommodate the coupling portion 130 when the second connecting portion 21 is sleeved on the first connecting portion 11, the operating structure 25 is arranged on the second connecting portion 21, the operating structure 25 and the clamping hole 24 are arranged correspondingly, the operating structure 25 is used to drive the coupling portion 130 located in the clamping hole 24 to deform (towards the direction close to the central axis of the first connecting portion 11, i.e. towards the direction close to the central axis of the second connecting portion 21) and move from the clamping hole 24 to the second channel 200. At this moment, pulling the first connecting portion 11 towards the direction away from the second connecting portion 21 can separate and remove the first connecting portion 11 from the second connecting portion 21 when the clamping hole 24 no longer accommodates and clamps the coupling portion 130. It should be noted that the clamping hole 24 is more conducive to the operating structure 25 driving the coupling portion 130 located in the clamping hole 24.

[0069] Further, as an example, in one embodiment of the present application, the operating structure 25 comprises a pressing portion 250 and a protruding portion 251, the protruding portion 251 is arranged on the inner side of the pressing portion 250 and at least partially extends into the clamping hole 24, and the pressing portion 250 can deform under the action of an external force. During the process of sleeving the second connecting portion 21 on the first connecting portion 11, the coupling portion 130 reaches the clamping hole 24 and presses the protruding portion 251 located in the clamping hole 24, the protruding portion 251 drives the pressing portion 250 to deform outwardly, so that the coupling portion 130 can be clamped into the connecting hole; under the action of an external force, the outer wall of the pressing portion 250 deforms inwardly, the protruding portion 251 is driven to press the coupling portion 130, and the coupling portion 130 is driven to deform inwardly by the pressing of the protruding portion 251 and retreats from the clamping hole 24 to the second channel 200. At this moment, pulling the first connecting portion 11 towards the direction away from the second connecting portion 21 can separate and remove the first connecting portion 11 from the second connecting portion 21 when the clamping hole 24 no longer accommodates and clamps the coupling portion 130. It should be noted that the top end of the protruding portion 251 can be designed as a spherical surface or an arc surface, which not only has a simple processing technology, but also can avoid the phenomenon of being stuck.

[0070] The number of operation structures 25 can be one or more. In order to facilitate the operator to hold and operate with two fingers, in the exemplary embodiment of the present application, the operation structure 25 is two, each operation structure 25 is located between two adjacent guide plates 220, the pressing portion 250 and the protruding portion 251 of each operation structure 25 are located at the end of the guide groove 2200 and are directed to the coupling portion 130 in the card hole 24 after the guide piece 120 slides through the corresponding guide groove 2200, so as to facilitate the extrusion of the coupling portion 130 under the condition of receiving external force. Exemplarily, the two operation structures 25 are oppositely arranged, facilitating the user to hold and operate with the thumb and the index finger.

[0071] Exemplarily, the second joint 20 can further include a blocking structure 26 arranged on the second connecting portion 21, the blocking structure 26 is arranged on the inner wall of the second channel 200 and extends to the position of the card hole 24, so as to block the outer wall of the pressing portion 250 from deforming and deepening into the second channel 200 under the condition of receiving external force.

[0072] Further, the operation structure 25 of the embodiment of the present application can further include a sleeve ring 252 sleeved on the outer wall of the second connecting portion 21, the pressing portion 250 extends from the sleeve ring 252 to the first connecting portion 11, and the protruding portion 251 is arranged on the inner side of the pressing portion 250 and is arranged adjacent to the end of the pressing portion 250.

[0073] The pressing portion 250, the protruding portion 251 and the sleeve ring 252 can be manufactured respectively and then assembled and fixed as a whole, or can be directly integrally manufactured as a whole. Exemplarily, in the embodiment of the present application, the pressing portion 250, the protruding portion 251 and the sleeve ring 252 are integrally manufactured as a whole, that is, the pressing portion 250, the protruding portion 251 and the sleeve ring 252 are integrally arranged.

[0074] The sleeve ring 252 can be an O-shaped ring or a C-shaped ring. When the sleeve ring 252 is a C-shaped ring, it can be deformed under the action of external force to make the opening wider, thereby facilitating the operator to detach it from the second connecting portion 21. In this way, when the pressing portion 250 and / or the protruding portion 251 is damaged, the sleeve ring 252 can be removed and replaced, and the operation process is simple and fast.

[0075] It can be understood that, in order to ensure the sealing performance of the joint assembly after assembly and avoid leakage of the joint assembly, the first connecting portion 11 is further sleeved with a sealing ring 15. In addition to the sealing function, the sealing ring 15 can also absorb vibration and impact, prolong the service life of the joint, and compensate for the change of the sleeve gap caused by the deformation of the pipeline when the temperature changes, thereby further improving the sealing performance.

[0076] The application further provides a faucet comprising the joint assembly as described above, which will not be described herein again.

[0077] The above has described the application in detail, and the principle and implementation of the application are described by using specific examples. The above description of the examples is only used to help understand the method of the application and its core idea. Meanwhile, for those skilled in the art, the specific implementation and application range can be changed according to the idea of the application. In conclusion, the content of the specification should not be understood as a limitation of the application.
