[0001] The utility model relates to the technical field of sanitary wares, in particular to a bent foot joint assembly. Background Art

[0002] At present, sanitary ware products are increasing day by day. As a main accessory of a faucet, a bent foot is an essential part. In common shower devices, usually two sets of bent foot assemblies with the same structure are adopted to connect a cold water pipe and a hot water pipe with a shower faucet respectively, so as to introduce cold water and hot water into the shower faucet respectively for mixing to form warm water suitable for showering, and then the faucet is connected to the water outlet end of the shower faucet to take water for showering.

[0003] The applicant previously applied for a utility model patent, and the authorization announcement number is CN222277788U. It discloses a multi-functional adjustable bent foot assembly, which includes a first pipe fitting connected to a pre-buried water pipe and a second pipe fitting connected to a water outlet control member. The first pipe fitting and the second pipe fitting are eccentrically arranged. Both the first pipe fitting and the second pipe fitting have a hollow structure. The outer periphery of the first pipe fitting is provided with a first external thread. The second pipe fitting includes a connection section connected to the water outlet control member and a movable section eccentrically arranged on the connection section. The movable section is fixedly connected to the connection section. The outer periphery of the connection section is provided with a second external thread. The movable section extends into the hollow part of the first pipe fitting, and the movable section axially slides in the first pipe fitting to adjust the overall length of the bent foot assembly. The movable section circumferentially rotates in the hollow part of the first pipe fitting to adjust the position of the connection section. A locking member for locking the second pipe fitting after the second pipe fitting moves is arranged on the first pipe fitting.

[0004] The above-mentioned bent foot assembly sets a threaded hole on the first pipe fitting and locks the first pipe fitting and the second pipe fitting by installing a screw in the threaded hole. However, as shown in the specification drawings of the above document Figure 1 the threaded holes of the bent foot assembly are arranged on the outer peripheral surface of the enlarged diameter section of the first pipe fitting. In this way, after the bent foot assembly is installed on the wall, when the screw is tightened, it is easily blocked by the wall, resulting in inconvenient installation of the screw and easy slipping of the screw during installation. Content of the Utility Model

[0005] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a bent foot joint assembly, which sets the locking hole on the end surface of the first pipe fitting close to the second pipe fitting, and the locking hole is inclined, which is convenient for the installation of the screw, will not be blocked, and the screw is not easy to slip during installation.

[0006] Technical solution of the utility model: A bent-foot joint assembly includes a first pipe fitting and a second pipe fitting. Both the first pipe fitting and the second pipe fitting have a hollow structure. The second pipe fitting includes a connecting section and a movable section eccentrically arranged on the connecting section. The movable section is located within the hollow part of the first pipe fitting, and the movable section can axially slide and circumferentially rotate relative to the first pipe fitting. A locking hole is provided on the end face of the first pipe fitting facing the connecting section of the second pipe fitting. The locking hole is inclined and communicates with the hollow part of the first pipe fitting. A locking member is connected in the locking hole to lock the second pipe fitting and the first pipe fitting.

[0007] With the above technical solution, the locking hole is inclined and is provided on the end face of the first pipe fitting facing the connecting section. This makes it so that when installing the locking member, it will not be hindered by the wall, and the installation is smoother. At the same time, due to the inclined setting of the locking hole, the locking member is not likely to slip during installation, which can optimize the mechanical properties of the threaded connection. Especially in the case of bearing large loads or vibrations, the inclination of the threaded hole can help evenly distribute the force, avoid local stress concentration, and improve the strength and stability of the connection.

[0008] Further setting of the utility model: The first pipe fitting includes a reduced-diameter section and an enlarged-diameter section. Threads are provided on the outer peripheral surface of the reduced-diameter section. The enlarged-diameter section is located at one end of the first pipe fitting close to the second pipe fitting. An inclined surface is provided on the enlarged-diameter section, and the locking hole is provided on the inclined surface.

[0009] With the above further setting, the reduced-diameter section is connected to the pre-buried water pipe, and the threaded connection is more convenient. The enlarged-diameter section is located outside the wall, and the locking hole is provided on the inclined surface, reducing the limitation of space when installing the locking member and facilitating the installation of the locking member.

[0010] Another further setting of the utility model: The connecting section includes a first connecting part and a second connecting part. The first connecting part is located between the movable section and the second connecting part. The first connecting part is arranged in a frustum shape, and the diameter of the first connecting part increases sequentially from the movable section to the second connecting part.

[0011] With the above another further setting, when installing the water outlet control member, it is located outside the connecting section and is fixed by screw connection. Therefore, the first connecting part is arranged in a frustum shape, which can prevent the screw from withdrawing and separating, making the structure between the water outlet control member and the bent foot more firm.

[0012] Another even further setting of the utility model: The inner end of the connecting section away from the movable section is provided with an internal hexagon.

[0013] With the above another even further setting, after installing the bent foot on the wall, by inserting a tool into the internal hexagon and rotating the connecting section, the first pipe fitting is driven to rotate to adjust the position of the bent foot, further improving the firmness of the bent foot.

[0014] Further improvement of the present utility model: Grooves are provided on both the second connecting portion and the movable section, and sealing rings are installed in each groove to make the connecting section and the water outlet control member in sealing fit, and the movable section and the first pipe fitting in sealing fit.

[0015] With the above further improvement, the sealing performance between the first pipe fitting and the second pipe fitting and between the second pipe fitting and the water outlet control member is good. The water flowing out of the water pipe can only flow from the second pipe fitting into the water outlet control member, avoiding leakage from the gap between the first pipe fitting and the second pipe fitting.

[0016] Further improvement of the present utility model: There is a diameter difference between the diameter of the movable section and the diameter of the first pipe fitting, so that the second pipe fitting swings and inclines relative to the first pipe fitting. At least three locking members and locking holes are provided to lock the movable section after the second pipe fitting swings and inclines relative to the first pipe fitting.

[0017] With the above further improvement, due to the obvious diameter difference between the diameter of the movable section and the aperture of the first pipe fitting, the first pipe fitting and the second pipe fitting can swing relative to each other and are inclined, so that the axis of the movable section is no longer parallel to the axis of the first pipe fitting and there is an included angle. When the pre-buried water pipe is skewed, the first pipe fitting and the second pipe fitting can be swung and inclined and then connected to the skewed pre-buried water pipe without demolishing the wall and reinstalling. After swinging, the movable section is locked by the locking member. At least three locking members lock the movable section, so that the movable section can always remain inclined relative to the first pipe fitting after locking, and the stability is good.

[0029] Such as Figures 1-6As shown in the figure, a bent-foot joint assembly includes a first pipe fitting 1 and a second pipe fitting 2. Both the first pipe fitting 1 and the second pipe fitting 2 have a hollow structure. The second pipe fitting 2 includes a connecting section 21 and a movable section 22 eccentrically arranged on the connecting section 21. The movable section 22 is located inside the hollow part of the first pipe fitting 1, and the movable section 22 can axially slide and circumferentially rotate relative to the first pipe fitting 1. The movable section 22 axially slides inside the first pipe fitting 1 to adjust the overall length of the bent-foot assembly. The movable section 22 circumferentially rotates inside the hollow part of the first pipe fitting 1 to adjust the position of the connecting section 21. The second pipe fitting 2 can rotate 360°. The first pipe fitting 1 is connected to the water pipe embedded in the wall, and the second pipe fitting 2 is connected to the water outlet control part. When it is necessary to adjust due to different depths of the two embedded water pipes, the second pipe fitting 2 is driven to axially slide inside the first pipe fitting 1, thus solving the problem of different depths. At the same time, when the positions of the two embedded water pipes are not on the same horizontal line or the distance between the two water pipes is too large or too small, the second pipe fitting 2 can be rotated to change the position of the connecting section 21, so that the water outlet control parts are on the same horizontal line, or the distance between the two second pipe fittings 2 is changed. After adjustment, the second pipe fitting 2 is locked by a locking part 4. A locking hole 3 is provided on the end face of the first pipe fitting 1 facing the connecting section 21 of the second pipe fitting 2. The locking hole 3 is inclined and communicates with the hollow part of the first pipe fitting 1. The locking part 4 is connected in the locking hole 3 to lock the second pipe fitting 2 and the first pipe fitting 1. Preferably, the locking hole 3 is a threaded hole, and the locking part 4 is a screw. The locking hole 3 is inclined and is provided on the end face of the first pipe fitting 1 facing the connecting section 21. In this way, the installation of the locking part 4 will not be hindered by the wall, and the installation is smoother. At the same time, due to the inclined setting of the locking hole 3, the locking part 4 is not easy to slip during installation, which can optimize the mechanical properties of the threaded connection. Especially in the case of bearing large loads or vibrations, the inclination of the threaded hole can help evenly distribute the force, avoid local stress concentration, and improve the strength and stability of the connection.

[0030] The first pipe fitting 1 includes a reduced-diameter section 11 and an enlarged-diameter section 12. Threads are provided on the outer peripheral surface of the reduced-diameter section 11. The enlarged-diameter section 12 is located at one end of the first pipe fitting 1 close to the second pipe fitting 2. An inclined surface 121 is provided on the enlarged-diameter section 12. The locking hole 3 is provided on the inclined surface 121. The reduced-diameter section 11 is connected to the embedded water pipe, and the threaded connection is more convenient. The enlarged-diameter section 12 is located outside the wall. The locking hole 3 is provided on the inclined surface 121, reducing the space limitation for the installation of the locking part 4 and facilitating the installation of the locking part 4.

[0031] The connecting section 21 includes a first connecting portion 211 and a second connecting portion 212. The first connecting portion 211 is located between the movable section 22 and the second connecting portion 212. The first connecting portion 211 is arranged in a frustum shape, and the diameter of the first connecting portion 211 increases successively from the movable section 22 towards the second connecting portion 212. When the water outlet control member is installed, it is located on the outer periphery of the connecting section 21 and is connected and fixed to the first connecting portion 211 by screws. Therefore, the first connecting portion 211 is arranged in a frustum shape, which can prevent the screws from withdrawing and disengaging, making the structure between the water outlet control member and the elbow more firm; the inner end portion of the connecting section 21 away from the movable section 22 is provided with an internal hexagon. After the elbow is installed on the wall, the connecting section 21 is rotated by inserting a tool into the internal hexagon to drive the first pipe fitting 1 to rotate and adjust the position of the elbow, further improving the firmness of the elbow; grooves 5 are provided on both the second connecting portion 212 and the movable section 22, and sealing rings are installed in each groove 5 to enable the connecting section 21 to be in sealing fit with the water outlet control member, and the movable section 22 to be in sealing fit with the first pipe fitting 1, so that the sealing performance between the first pipe fitting 1 and the second pipe fitting 2 and between the second pipe fitting 2 and the water outlet control member is good. The water flowing out of the water pipe can only flow from the second pipe fitting 2 into the water outlet control member, avoiding flowing out from the gap between the first pipe fitting 1 and the second pipe fitting 2 and causing water leakage.

[0032] There is a diameter difference between the diameter of the movable section 22 and the diameter of the first pipe fitting 1, so that the second pipe fitting 2 can swing and tilt relative to the first pipe fitting 1. At least three locking members 4 and locking holes 3 are provided to lock the movable section 22 after the second pipe fitting 2 swings and tilts relative to the first pipe fitting 1. Due to the obvious diameter difference between the diameter of the movable section 22 and the aperture of the first pipe fitting 1, the first pipe fitting 1 and the second pipe fitting 2 can swing relative to each other and are arranged obliquely, so that the axis of the movable section 22 is no longer parallel to the axis of the first pipe fitting 1 and there is an included angle. When the pre-buried water pipe is skewed, the first pipe fitting 1 and the second pipe fitting 2 can be swung and tilted and then connected to the skewed pre-buried water pipe without knocking down the wall for reinstallation. After swinging, the movable section 22 is locked by the locking member 4. At least three locking members 4 lock the movable section 22, so that the movable section 22 can always remain tilted with respect to the first pipe fitting 1 after being locked, and the stability is good.
