Description

Technical Field

[0001] The utility model relates to the technical field of water pipe fittings, and more specifically, to a faucet joint and a pipeline system. Background Technique

[0002] In the PVC water supply pipeline system of civil buildings, a faucet is often required to be connected to the water outlet end to control the water flow. However, since the outer wall of the water inlet of the faucet usually has a threaded design, it cannot be directly connected to the PVC water supply pipe. Therefore, in the actual installation process, a joint (elbow) is usually required as an intermediate connecting piece to realize the connection between the faucet and the water supply pipe.

[0003] One end of the traditional joint (elbow) is designed with internal threads for connecting with the external threads of the faucet, while the other end has a smooth inner wall and is adhesively fixed to the outer wall of the pipe through glue, so as to ensure that the faucet can be stably installed in the water supply pipeline system. However, this traditional installation method has an obvious drawback. When the joint (elbow) is damaged or needs to be replaced, due to the characteristics of the glue connection, the joint (elbow) often cannot be easily separated from the pipe. This usually requires cutting from the pipe end and then reconnecting a new joint (elbow). This method not only reduces the installation height of the faucet, but may also have an adverse impact on the use effect. If it is necessary to restore the original installation height, an additional straight-through pipe and a short section of pipe need to be added, which undoubtedly increases the cost and complexity of replacement.

[0004] The Chinese patent of the prior art CN201520148775.3 discloses a PPR internal thread insert plastic water pipe elbow. The water pipe elbow is composed of a copper insert, a plastic elbow, a first sealing ring and a second sealing ring. The bottom of the copper insert is provided with a sealing groove, and the periphery of the copper insert is provided with a dovetail groove. The first sealing ring is embedded in the sealing groove, and the second sealing ring is embedded in the dovetail groove. The outer shape of the plastic elbow matches that of the copper insert. The copper insert and the plastic elbow are in shape fit through the dovetail groove, and a first sealing ring and a second sealing ring are provided between the copper insert and the plastic elbow to achieve the effect of multiple leak prevention. However, after one end of the elbow is connected to the water supply pipe, it cannot be easily separated, resulting in difficult replacement of the elbow. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the problem of difficult replacement of the existing technology joints. The utility model provides a faucet joint and a pipeline system, which can realize the detachable connection between the joint and the water supply pipe and facilitate the replacement of the joint.

[0006] To achieve the above object, a faucet joint of the present technical solution includes a main body, a receiving pipe, and a locking assembly. The main body is a tubular structure. One end of the receiving pipe is used to be fixed to a water pipe, and the other end of the receiving pipe is slidably connected to one end of the main body. The locking assembly is connected to the end of the main body close to the receiving pipe, and the other end of the locking assembly presses against the pipe wall of the receiving pipe to fix the receiving pipe. The other end of the main body is used to be connected to a faucet.

[0007] In the present technical solution, one end of the receiving pipe is first fixed to the water outlet end of the water pipe, and one end of the main body is connected to the faucet. The locking assembly is sleeved on the main body, and then the end of the receiving pipe far from the water pipe is inserted into the end of the main body far from the faucet. The telescopic length of the receiving pipe in the main body is slidably adjusted to adapt to the installation height of the faucet. The locking assembly is installed so that one end of the locking assembly presses against the outer wall of the receiving pipe, thereby realizing the fixation of the receiving pipe and the main body. When it is necessary to adjust the height of the faucet or replace the main body of the joint, only the installation position of the locking assembly needs to be adjusted so that one end of the locking member loosens the receiving pipe, and then the sliding adjustment of the receiving pipe can be carried out or the main body and the receiving pipe can be separated to replace the main body of the joint. During the adjustment or replacement process, there is no need to damage the water pipe, and the adjustment and replacement are more convenient; in the maintenance of old pipelines, the old pipelines refer to pipelines that do not use the present utility model. Due to the function of the receiving pipe to adjust the installation length, when the water pipe is cut and combined with other straight pipes to connect the receiving pipe, the requirement for the cutting size accuracy is relatively low, which makes the installation more convenient, the error tolerance higher, and the maintenance cost lower.

[0008] Further, in order to facilitate the insertion of the receiving pipe into one end of the main body, one end of the main body is provided with a first socket, and one end of the receiving pipe is slidably connected to the inner wall of the first socket. The inner diameter of the first socket is slightly larger than the outer diameter of the receiving pipe.

[0009] Further, in order to fix the receiving pipe, the locking assembly includes a connecting sleeve and a sealing ring. An annular receiving groove is provided on the inner wall of the first socket, and the sealing ring is installed in the receiving groove. External threads are provided on the outer wall of the first socket, and internal threads are provided on the inner wall of the connecting sleeve. The connecting sleeve is screwed onto the first socket. A pressing block is formed by the inward protrusion of the end of the connecting sleeve. When the connecting sleeve is screwed into the first socket, the pressing block squeezes the sealing ring located in the receiving groove so that the sealing ring undergoes elastic deformation and presses against the outer wall of the receiving pipe. After the receiving pipe is inserted into the first socket, the connecting sleeve is screwed. As the connecting sleeve is screwed into the main body along the first socket, the pressing block formed at its end gradually squeezes the sealing ring, and the other side of the sealing ring is subjected to the reaction force of the receiving groove, causing the sealing ring to deform. The deformation process is as follows: as the axial length of the sealing ring is squeezed, the thickness of the sealing ring increases accordingly, so that the sealing ring uniformly presses against the outer wall of the receiving pipe to achieve the fixation and sealing of the receiving pipe.

[0010] Further, to ensure the sealing performance at the connection between the receiving pipe and the first socket, the axial length of the sealing ring is greater than or equal to the axial width of the receiving groove. To avoid interference with the sealing ring during the insertion or sliding adjustment of the receiving pipe, the inner diameter of the sealing ring is greater than or equal to the outer diameter of the receiving pipe.

[0011] Further, to facilitate the screwing of the connection sleeve, the outer wall of the connection sleeve is provided with knurling, which serves an anti-slip function.

[0012] Further, a second socket is provided at one end of the main body away from the receiving pipe. A metal insert is fixed to the inner wall of the second socket, and an internal thread for threaded connection with a faucet is provided on the inner wall of the metal insert. The metal insert can ensure the sealing performance of the faucet connection, and at the same time can improve the structural strength of the joint, enhancing the durability and reliability of the connection.

[0013] Further, to facilitate the connection between the joint and the water outlet end of the water supply pipe, a third socket for connecting the water supply pipe is provided at one end of the receiving pipe away from the main body. The inner diameter of the third socket is slightly larger than the outer diameter of the water supply pipe, which can better accommodate the water supply pipe, and different diameters of water supply pipes can be adapted by replacing receiving pipes of different sizes, showing strong compatibility.

[0014] Further, to adapt to the installation environment where the water outlet end of the water supply pipe is coaxial with the faucet, the main body is of a straight pipe structure.

[0015] Further, to adapt to the installation environment where the water outlet end of the water supply pipe is non - coaxial with the faucet, the main body is of a bent pipe structure.

[0016] To achieve the above - mentioned purpose, a pipeline system of the present technical solution includes the above - mentioned faucet joint, and also includes a water supply pipe and a faucet. The water outlet end of the water supply pipe is fixedly connected to the end of the receiving pipe away from the main body through an adhesive, and the faucet is detachably connected to the end of the main body away from the receiving pipe.

[0017] In this embodiment, the water outlet end of the water supply pipe is connected to the faucet through a joint. When the joint needs to be replaced, loosen the connection sleeve, separate the receiving pipe and the faucet at both ends of the main body, and then replace the main body without damaging the structure of the water supply pipe; when the position of the joint needs to be adjusted, loosen the connection sleeve, slide and adjust the telescopic length of the receiving pipe in the main body, and then tighten the connection sleeve again.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] 1. The utility model is connected to a faucet through a receiving pipe. The receiving pipe is slidably connected to one end of the main body and fixed by a locking component, making the receiving pipe and the main body detachable. When the joint main body needs to be replaced, only the locking component needs to be disassembled to separate the main body and the receiving pipe, without the need to cut from the water outlet end of the faucet. This makes the replacement of the joint main body more convenient, saving time and labor costs.

[0020] 2. By sliding and adjusting the position of the receiving pipe at one end of the main body, the length of the water outlet end of the water supply pipe can be telescopically adjusted, which can solve the problem that the position of the water outlet end of the water supply pipe does not match the installation position of the faucet, avoid cutting the water supply pipe, has strong compatibility, and is more convenient to install.

[0021] 3. By installing a metal insert into the third socket, it is for the installation of the faucet, with strong durability and strong sealing performance. Brief Description of the Drawings

[0030] The technical solutions of the present utility model will be further specifically described below through specific embodiments and in conjunction with the drawings:

[0031] Embodiment 1:

[0032] This embodiment is the first embodiment of a faucet joint. As Figure 1 shown, it includes a main body 1, a receiving pipe 2, and a locking assembly 3. The main body 1 is a tubular structure. One end of the receiving pipe 2 is used to be fixed to the water supply pipe 5. The other end of the receiving pipe 2 is slidably connected to one end of the main body 1. The locking assembly 3 is detachably connected to the end of the main body 1 close to the receiving pipe 2. The other end of the locking assembly 3 presses against the pipe wall of the receiving pipe 2 to fix the receiving pipe 2. The other end of the main body 1 is used to be detachably connected to the faucet 6.

[0033] In this embodiment, this joint solves the problem that the water supply pipe 5 cannot be directly connected to the faucet 6. The detachable connection between the receiving pipe 2 and the main body 1 and the telescopic adjustment of the receiving pipe 2 are realized through the locking assembly 3. The main body 1 and the receiving pipe 2 are made of PVC material. Its advantages mainly include light weight, excellent chemical resistance, small fluid resistance, large mechanical strength, good electrical insulation, no influence on water quality, and simple construction. In addition, the PVC pipe also has advantages such as good tensile and compressive strength, high water conveyance capacity, good corrosion resistance and chemical resistance, good water tightness, and adaptability to different environments, making it widely used in the fields of construction, agriculture, industry, etc.

[0034] Specifically, as Figures 2 to 4 shown, one end of the main body 1 is provided with a first socket 11. One end of the receiving pipe 2 is slidably connected to the inner wall of the first socket 11. In this embodiment, the outer diameter of the receiving pipe 2 is adapted to the inner diameter of the first socket 11.

[0035] Specifically, as Figure 2As shown, the locking assembly 3 includes a connecting sleeve 31 and a sealing ring 32. An annular accommodation groove 111 is provided on the inner wall of the first socket 11. The sealing ring 32 is installed in the accommodation groove 111. An external thread is provided on the outer wall of the first socket 11, and an internal thread is provided on the inner wall of the connecting sleeve 31. The connecting sleeve 31 is screwed onto the first socket 11. A pressing block 311 is formed by the inward protrusion at the end of the connecting sleeve 31. When the connecting sleeve 31 is screwed into the first socket 11, the pressing block 311 squeezes the sealing ring 32 located in the accommodation groove 111, causing the sealing ring 32 to undergo elastic deformation and tightly press against the outer wall of the receiving pipe 2.

[0036] In this embodiment, the sealing ring 32 is made of silicone rubber and has excellent high-temperature resistance. It can maintain stable sealing performance within a wide temperature range. Silicone is non-toxic, odorless, and has stable chemical properties. It is insoluble in water and any solvent. The end of the connecting sleeve 31 forms an L-shaped pressing block 311, which can slide in the accommodation groove 111 as the connecting sleeve 31 is screwed in, thereby evenly squeezing the sealing ring 32 located in the accommodation groove 111. The sealing ring 32 is elastically deformed under the extrusion, causing the inner ring of the sealing ring 32 to squeeze the outer wall of the receiving pipe 2, achieving the fixation and sealing of the receiving pipe 2.

[0037] Specifically, as Figure 4 shown, the axial length of the sealing ring 32 is greater than or equal to the axial width of the accommodation groove 111, and the inner diameter of the sealing ring 32 is greater than or equal to the outer diameter of the receiving pipe 2.

[0038] In this embodiment, the axial length of the sealing ring 32 is equal to the axial width of the accommodation groove 111. When the sealing ring 32 is placed in the accommodation groove 111 and not under extrusion pressure, the inner ring of the sealing ring 32 is flush with the inner wall of the first socket 11, enabling the receiving pipe 2 to slide telescopically within the first socket 11 and avoiding interference with the sealing ring 32.

[0039] Specifically, as Figure 2 shown, the outer wall of the connecting sleeve 31 is provided with knurling 312.

[0040] In this embodiment, in order to increase the friction when screwing the connecting sleeve 31 and prevent hand slippage, it is achieved by providing knurling 312 on the outer wall of the connecting sleeve 31.

[0041] Specifically, as Figure 3 、 4 shown, a third socket 21 for connecting to a water supply pipe 5 is provided at one end of the receiving pipe 2 away from the main body 1.

[0042] In this embodiment, the water supply pipe 5 can be connected to the third socket 21 through an adhesive.

[0043] Specifically, as Figure 1 shown, the main body 1 is a bent pipe structure.

[0044] In this embodiment, the main body 1 is a right-angled bent pipe structure, which is applicable to the case where the water supply pipe 5 is perpendicular to the faucet 6. When the water supply pipe 5 and the faucet 6 are coaxial, a straight pipe structure can also be used to realize the connection between the water supply pipe 5 and the faucet 6.

[0045] The working principle of a faucet joint in this embodiment is as follows:

[0046] First, fix the receiving pipe 2 to the water supply pipe 6 through the third socket 21 by gluing. Put the sealing ring 32 into the receiving groove 111, put on the connecting sleeve 31, then extend the end of the receiving pipe 2 away from the third socket 21 into the first socket 11, slide and adjust the extending length of the receiving pipe 2 in the first socket 11, tighten the connecting sleeve 31 until the receiving pipe 2 cannot move, and finally install the faucet 6 at the end of the main body 1 away from the first socket 11. When the main body 1 needs to be replaced, it is not necessary to cut the pipe material of the water supply pipe 5, but only loosen the connecting sleeve 31 to separate the receiving pipe 2 from the first socket 11 to remove the main body 1.

[0047] Embodiment 2:

[0048] This embodiment is the second embodiment of a faucet joint. This embodiment is similar to Embodiment 1, and the difference is that in this embodiment, as Figure 2 、 4 shown, a second socket 12 is provided at the end of the main body 1 away from the receiving pipe 2, a metal insert 4 is fixed to the inner wall of the second socket 12, and an internal thread for threaded connection with the faucet 6 is provided on the inner wall of the metal insert 4.

[0049] In this embodiment, the metal insert 4 is in interference fit with the second socket 12 and is reinforced by an adhesive.

[0050] Embodiment 3:

[0051] This embodiment is the first embodiment of a pipeline system. As Figure 5 shown, it includes a faucet joint as described above, and also includes a water supply pipe 5 and a faucet 6. The water outlet end of the water supply pipe 5 is fixed to the end of the receiving pipe 2 away from the main body 1 by an adhesive, and the faucet 6 is detachably connected to the end of the main body 1 away from the receiving pipe 2.

[0052] In this embodiment, the pipeline system has strong sealing performance, reliable connection, convenient installation, and avoids damaging the integrity of the water supply pipe 5.

[0053] Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present utility model. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present utility model.
