Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, and in particular to a faucet connecting pipe assembly. Background Technology

[0002] In water-using scenarios such as bathrooms and kitchens, the faucet connection pipe is a key component for connecting the faucet to the air outlet assembly. It not only needs to have a stable ventilation function, but also needs to adapt to the angle adjustment requirements of different installation environments. Therefore, the corrugated pipe structure is widely used in the main design of faucet connection pipes due to its good flexibility and deformation capability.

[0003] In existing technologies, the connection between the two ends of the faucet connecting pipe and the air outlet component / faucet generally adopts a combination structure of "rubber seal with buckle". That is, a rubber ring is set at the connection point to achieve a seal, and then the connecting pipe and the docking component are directly locked and fixed by a buckle. This connection method has significant drawbacks: First, the buckle connection is a one-time or semi-permanent fixing structure. In subsequent use, when the connecting pipe becomes blocked, the rubber ring ages and leaks air, or the air outlet component needs to be replaced, the disassembly process requires special tools to forcibly pry open the buckle. This is not only cumbersome, but also very easy to cause the buckle to break and the connecting pipe itself to be damaged, resulting in the scrapping of the entire connecting pipe, which greatly increases maintenance costs and difficulty. Second, after long-term use, the rubber seal is prone to aging and deformation, and the non-removable nature of the buckle structure makes it impossible to replace the seal separately, further reducing the service life of the connecting pipe.

[0004] In summary, existing faucet connecting pipes have technical problems in terms of connection method and structural design, such as being difficult to disassemble, inconvenient to maintain, high maintenance costs, and components that cannot be replaced individually. There is an urgent need for a faucet connecting pipe structure that can solve the above problems. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention provides a faucet connecting pipe assembly, which can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] According to one aspect of the present invention, it includes: a connecting pipe, the two ends of which are respectively connected to an air outlet assembly and a faucet assembly; the two ends of the connecting pipe are respectively detachably connected to a first connector and a second connector; it also includes a first sleeve nut, a multi-way connecting pipe, and a second sleeve nut; the first sleeve nut is rotatably sleeved on the outside of the first connector; the first sleeve nut is threadedly connected to one end of the air outlet assembly; one end of the multi-way connecting pipe is fixedly connected to the second connector, and the other end is engaged with the second sleeve nut; the second sleeve nut is threadedly connected to one end of the faucet assembly.

[0008] Furthermore, the connecting pipe is a corrugated pipe, one end of which is threaded to the first connector and the other end of which is threaded to the second connector, and the space between the corrugated pipe and the first and second connectors is filled with sealant.

[0009] Furthermore, a second limiting boss is formed by extending inward from one end edge of the first sleeve nut, and the lower end face of the second limiting boss abuts against the upper end face of the first connector.

[0010] Furthermore, the multi-way connecting pipe is a tee pipe, and the branch pipe of the tee pipe is equipped with a wire plug for wiring.

[0011] Furthermore, the wire plug is detachably plugged at the end of the branch pipe, and the end of the branch pipe is provided with at least one positioning groove at intervals. At least one end of the wire plug extends toward the positioning groove and is provided with a positioning protrusion, which fits into the positioning groove.

[0012] Furthermore, one end of the multi-way connecting pipe extends outward in an annular shape to form a first limiting boss, and one end of the second sleeve nut extends inward in an annular shape to form a buckle, and the edge of the buckle is distributed with several second grooves at intervals. When the second sleeve nut is sleeved on one end of the multi-way connecting pipe, the buckle cooperates with the first limiting boss.

[0013] Furthermore, the upper surface of the first limiting boss is provided with a plurality of reinforcing ribs at intervals, and the plurality of reinforcing ribs abut against the inner circumferential surface of the second sleeve nut.

[0014] Furthermore, the second connector is ultrasonically welded to one end of the multi-channel connecting pipe.

[0015] Furthermore, a seal is fitted between the multi-way connecting pipe and the second sleeve nut; a seal is also fitted between the first connector and the air outlet assembly.

[0016] Furthermore, one end of the second sleeve nut is provided with an internal thread for engaging with the faucet assembly.

[0017] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0018] Firstly, the two ends of the connecting pipe are connected to the air outlet assembly and the faucet assembly respectively through a detachable first connector and a second connector. This abandons the traditional non-detachable snap-fit ​​structure and replaces it with a combination of "the first sleeve nut threadedly connects to the air outlet assembly and the second sleeve nut snaps in place and then threadedly connects to the faucet assembly". During subsequent maintenance, it can be disassembled simply by turning the sleeve nut in the opposite direction without damaging the connecting pipe or connector, thus solving the problems of cumbersome disassembly and easily damaged parts. The overall structure, through detachable connection and threaded sealing, ensures the stability of the ventilation function and meets the needs of individual component replacement during subsequent maintenance, greatly reducing maintenance costs and operational difficulty.

[0019] Secondly, the bellows is connected to the first and second connectors via threads, and the thread gaps are filled with sealant. Compared with traditional rubber seals, the sealant can more comprehensively cover the thread gaps, preventing moisture from seeping in from the threaded joints. At the same time, the detachable nature of the threaded connection makes it easy to replace the bellows or connectors separately later, further improving maintenance convenience. The aging resistance of the sealant is better than that of ordinary rubber rings, which can extend the service life of the sealing structure, reduce air leakage caused by the aging of the seals, and reduce the frequency of maintenance.

[0020] Thirdly, the second limiting boss of the first sleeve nut abuts against the upper end face of the first connector, which can precisely limit the axial displacement of the first sleeve nut, preventing it from shifting and causing loosening when rotating to connect the air outlet assembly, thus ensuring the stability of the threaded connection. While limiting the displacement, the limiting structure does not affect the free rotation of the first sleeve nut around the first connector, satisfying both the operational flexibility during assembly and ensuring the structural stability after connection, thus preventing sealing failure due to sleeve nut shaking.

[0021] Fourth, the multi-way connection pipe is designed as a T-shaped pipe, with its branch pipes specifically for wiring. This allows for the centralized storage of connection wires for control circuit boards and sensors, water pipes, soap solution pipes, and other wiring, preventing the wiring from being exposed to moisture or damaged by external forces. This solves the problems of messy and easily damaged traditional wiring. The installation of the wire plug can seal the end of the branch pipe, preventing moisture and dust from entering the branch pipe and contaminating the wiring. It also prevents the wiring from coming out of the branch pipe, ensuring the neatness of the wiring and improving the safety and stability of the wiring.

[0022] Fifth, the plug is removable by engaging with the positioning groove at the end of the branch pipe via a positioning protrusion. When the wiring needs to be adjusted or the plug needs to be replaced, it can be pulled out directly without damaging the branch pipe or the plug, making maintenance convenient. The precise engagement of the positioning protrusion and the positioning groove ensures the sealing of the plug, preventing moisture from seeping in from the end of the branch pipe, and also preventing the plug from falling off due to vibration or external force during use, ensuring the stability of the wiring structure. The design of at least one positioning groove and positioning protrusion simplifies the assembly operation, allowing the plug to be fixed without complicated alignment, thus improving assembly efficiency.

[0023] Sixth, the first limiting boss of the multi-way connecting pipe and the snap-fit ​​of the second sleeve nut can quickly achieve snap-fit ​​positioning of the two. Compared with the traditional threaded connection, the snap-fit ​​structure is more convenient to assemble and can limit the axial displacement of the second sleeve nut, preventing it from falling off during use. The second groove on the edge of the snap-fit ​​can disperse the stress concentration during snap-fit, prevent the snap-fit ​​from breaking due to excessive force, and extend the service life of the second sleeve nut.

[0024] Seventh, the reinforcing rib on the upper surface of the first limiting boss abuts against the inner circumferential surface of the second sleeve nut to prevent radial wobbling of the second sleeve nut during use, thereby improving the stability of the overall structure and preventing loosening of the threaded connection and failure of the seal due to wobbling; the reinforcing rib can enhance the structural strength of the first limiting boss and prevent it from deforming when subjected to the pressure of the second sleeve nut for a long time, further extending the service life of the multi-way connecting pipe and ensuring the long-term reliability of the snap-fit ​​structure.

[0025] Eighth, the first connector and the air outlet component, as well as the multi-way connecting pipe and the second sleeve nut, are all equipped with sealing components to form a double sealing structure. Compared with a single seal, this can further enhance the water vapor barrier effect, prevent water vapor that seeps in from the connection point from affecting the internal structure of the component, and improve the overall waterproof performance.

[0036] like Figures 1 to 7 As shown, this solution provides a faucet connection pipe assembly.

[0037] Please see Figures 1 to 7 The assembly includes: a connecting pipe 1, with its two ends connected to an air outlet assembly (not shown) and a faucet assembly (not shown), respectively. The two ends of the connecting pipe 1 are detachably connected to a first connector 2 and a second connector 4. Specifically, the connecting pipe 1 is a corrugated pipe, preferably a steel wire corrugated pipe. One end of the corrugated pipe is threaded to the first connector 2, and the other end is threaded to the second connector 4. Sealant (not shown) is filled between the corrugated pipe and the first connector 2 and the second connector 4. The sealant is a direct application of existing technology, and its principle will not be elaborated here. When assembling the corrugated pipe, the first connector 2, and the second connector 4, sealant is first applied to one end of the corrugated pipe, and then the sealant-coated end is screwed into the first connector 2. It also includes a first sleeve nut 3, which is rotatably fitted onto the outside of the first connector 2. The first sleeve nut 3 is threadedly connected to one end of the air outlet assembly. One end edge of the first sleeve nut 3 extends inward to form a second limiting boss 31, and the lower end face of the second limiting boss 31 abuts against the upper end face of the first connector 2. The other end of the first sleeve nut 3 has an internal thread that is threadedly connected to the air outlet assembly. Preferably, a sealing element 7 is assembled between the first connector 2 and the air outlet assembly.

[0038] Please see Figures 1 to 7The assembly also includes a multi-way connecting pipe 5 and a second sleeve nut 8. One end of the multi-way connecting pipe 5 is fixedly connected to a second connector 4. Preferably, the second connector 4 and one end of the multi-way connecting pipe 5 are ultrasonically welded. The other end of the multi-way connecting pipe 5 is snapped into the second sleeve nut 8. Preferably, a sealing element 7, which is an O-ring, is installed between the multi-way connecting pipe 5 and the second sleeve nut 8. The second sleeve nut 8 is threaded to one end of the faucet assembly. Preferably, the multi-way connecting pipe 5 is a tee pipe, and the branch pipe 51 of the tee pipe is equipped with a wire plug 6 for wiring. The wire plug 6 is made of rubber or silicone. One end of the wire plug 6 is provided with multiple wire holes 62. In this embodiment, the number of wire holes 62 is three. The three wire holes 62 are respectively used for threading the connection wires of the control circuit board sensor, the water pipe, and the soap solution pipe connector. The wire plug 6 is detachably plugged at the end of the branch pipe 51. At least one positioning groove 53 is provided at the end of the branch pipe 51. At least one end of the wire plug 6 extends toward the positioning groove 53 and is provided with a positioning protrusion 61, which fits into the positioning groove 53.

[0039] Please see Figures 1 to 7 One end of the multi-way connecting pipe 5 extends outward in a ring shape to form a first limiting boss 52, and one end of the second sleeve nut 8 extends inward in a ring shape to form a buckle 82. The edge of the buckle 82 is spaced with several second grooves 83. When the second sleeve nut 8 is fitted onto one end of the multi-way connecting pipe 5, the buckle 82 engages with the first limiting boss 52. Preferably, the several second grooves 83 are equidistantly distributed on the buckle 82. The upper surface of the first limiting boss 52 has several reinforcing ribs 521 spaced apart, and these reinforcing ribs 521 abut against the inner circumferential surface of the second sleeve nut 8. Preferably, the several reinforcing ribs 521 are equidistantly distributed on the first limiting boss 52. Preferably, one end of the second sleeve nut 8 has an internal thread for engaging with the faucet assembly, and preferably, this internal thread has several first grooves 81 spaced apart. The several first grooves 81 facilitate the removal of the second sleeve nut 8 from the mold.

[0040] Working principle:

[0041] First, apply sealant evenly to one end of the bellows, then screw one end of the bellows into the first connector 2, connecting it with the threaded joint of the first connector 2. Next, insert the first sleeve nut 3 from the end of the first connector 2 away from the bellows, so that the lower end face of the second limiting boss 31 inside the first sleeve nut 3 abuts against the upper end face of the first connector 2. The second limiting boss 31 restricts the axial displacement of the first sleeve nut 3, while ensuring that it can rotate freely around the first connector 2. Assemble the sealing element 7 into the first connector 2, and rotate the first sleeve nut 3 so that its internally threaded end connects with the externally threaded end of the air outlet assembly until it is tightened, thus completing the connection and fixation between the connecting pipe 1 and the air outlet assembly. For subsequent disassembly, simply rotate the first sleeve nut 3 in the opposite direction without damaging the components.

[0042] After evenly applying sealant to the other end of the bellows, screw it into the second connector 4 to make it threadedly connected with the second connector 4; assemble the sealing element 7 onto one end of the multi-way connecting pipe 5, and slip the second sleeve nut 8 onto the end of the multi-way connecting pipe 5 away from the second connector 4, so that the buckle 82 inside the second sleeve nut 8 engages with the first limiting boss 52 on the outside of the multi-way connecting pipe 5. The second groove 83 on the edge of the buckle can reduce stress concentration during engagement. At the same time, the reinforcing rib 521 on the upper end of the first limiting boss 52 abuts against the inner circumferential surface of the second sleeve nut 8, enhancing structural stability; rotate the second sleeve nut 8 so that its internally threaded end is threadedly connected to the externally threaded end of the faucet assembly, completing the connection and fixation between the connecting pipe 1 and the faucet assembly. Disassembly can be done by rotating in the opposite direction, making the operation convenient;

[0043] If wiring is required, the connecting wires of the control circuit board sensor, water pipe, soap solution pipe connectors, etc., are passed through the corresponding wire holes 62 on the wire plug 6; align the positioning protrusion 61 of the wire plug 6 with the positioning groove 53 at the end of the branch pipe 51 of the multi-way connecting pipe 5, and plug the wire plug 6 into the end of the branch pipe 51. The positioning protrusion 61 and the positioning groove 53 are used to fix it. If the wiring needs to be adjusted or the wire plug 6 needs to be replaced later, it can be pulled out directly without damaging the overall structure.

[0044] Through the above assembly steps, each component can be detachably connected and effectively sealed, which not only meets the needs of ventilation and wiring, but also greatly improves the convenience of maintenance and reduces maintenance costs and resource waste.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
