Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically a structure for preventing the twisting and deformation of the inner and outer water outlet pipes of a faucet. Background Technology

[0002] Faucets are an indispensable part of modern household and industrial water systems. They are used to control the flow of water, turn it off, and regulate the water temperature. Traditional faucet designs typically include one or more handles to operate the internal valve mechanism. However, in certain designs, especially in some earlier models, the internal structure of the faucet may be defective, causing the nozzle to not rotate smoothly during use, and resulting in twisting and deformation of the connected internal and external water pipes due to excessive resistance.

[0003] The "revolve" here refers to the inner and outer pipes of the faucet. Tube The difficulty in rotating and getting stuck around the center line of the pipe during operation increases the possibility of the inner and outer pipes twisting and deforming, thus making it difficult for the faucet to dispense water. Utility Model Content

[0004] The purpose of this utility model is to provide a structure for preventing the twisting and deformation of the internal and external water outlet pipes of a faucet, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A structure for preventing the twisting and deformation of the inner and outer water outlet pipes of a faucet includes a main body, a connector fixedly connected to the main body, an outer pipe fixedly connected to the connector, an inner pipe fixedly connected to the main body inside the outer pipe, and a nozzle connected to the other end of the outer pipe and the inner pipe.

[0007] The nozzle includes a housing, inside which is a connector three. An outer tube passes through the housing and abuts against the top of connector three. An inner tube passes through the interior of connector three and is fixedly connected to a connector one. A sealing ring two is located on the outside of connector one, and the sealing ring two is coated with lubricating oil. Connector one is located inside connector three. One end of the sealing ring two abuts against connector one, and the other end contacts the inner sidewall of connector three. Connector three has an external hexagonal head and an external thread on the upper part. The housing has an internal hexagonal head. The external hexagonal head is engaged in the internal hexagonal head. The upper part of the internal hexagonal head has a step one, and a locking nut is on the step one for locking connector three in the housing. A nozzle is fixedly connected to the lower end of connector three. The nozzle communicates with the inner tube. Several spray nozzles are arranged in a ring at the bottom of the nozzle.

[0008] Furthermore, the main body includes an outer shell, a second connector is installed inside the outer shell, an installation groove is provided on the outer side of the second connector, a fixing ring is placed on the installation groove, the main body and the fixing ring are provided with threaded holes communicating with each other, a screw is threaded into the threaded hole, one end of the inner tube is fixedly connected to the second connector and communicates with the inside of the outer shell, a cold water pipe and a hot water pipe communicating with the inner tube are fixedly connected inside the outer shell, and a threaded fitting is threadedly connected to the bottom of the outer shell.

[0009] Furthermore, both the outer and inner tubes are U-shaped bends.

[0010] Furthermore, a fixing rod is fixedly connected to the side of the first connector, and a magnetic attractor is fixedly connected to the other end of the fixing rod. A magnet is fixedly connected between the housing and the third connector.

[0011] Furthermore, each end of the inner tube is provided with at least one inner groove, and each inner groove is provided with a sealing ring.

[0012] Furthermore, the second connector is provided with an inner groove below the mounting groove, and a sealing ring is provided on the inner groove.

[0013] The beneficial effects of this utility model are:

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please refer to Figure 1-6 ;

[0026] A structure for preventing twisting and deformation of the inner and outer water pipes of a faucet includes a main body 4, a connector 3 fixedly connected to the main body 4, an outer pipe 1 fixedly connected to the connector 3, an inner pipe 2 fixedly connected to the main body 4 inside the outer pipe 1, so that the inner pipe 2 and the outer pipe 1 will not rotate, and a nozzle 7 is connected to the other end of the outer pipe 1 and the inner pipe 2.

[0027] The nozzle 7 includes a housing 91, within which a connector 92 is provided. An outer tube 1 passes through the housing 91 and abuts against the top of the connector 92. An inner tube 2 passes through the interior of the connector 92 and is fixedly connected to a connector 10, preventing the connector 10 from rotating. A sealing ring 11, coated with lubricating oil, is located outside the connector 10. One end of the sealing ring 11 abuts against the connector 10, and the other end contacts the inner wall of the connector 92. The sealing ring 11 seals the interior of the nozzle 7, achieving a dynamic seal between the nozzle 7 and the connector 92 to prevent leakage. Simultaneously, the connector 3 92 is allowed to rotate; the connector 3 92 has an external hexagon 13 on the outside and an external thread 15 on the top, and an internal hexagon 14 inside the housing 91. The external hexagon 13 is engaged in the internal hexagon 14, so that the two rotate synchronously. The internal hexagon 14 has a step 12 on the top, and a locking nut 9 on the step 12, which is used to lock the connector 3 92 in the housing 91. The lower end of the connector 3 92 is fixedly connected to a nozzle 93. The nozzle 93 is connected to the inner tube 2. The bottom of the nozzle 93 is provided with several water spray holes in a ring, so that when the nozzle 7 rotates, the inner and outer water outlet pipes and the connector 10 do not rotate. The other parts connected to the nozzle 7 can rotate together with the nozzle 7.

[0028] In this embodiment, the main body 4 includes a shell 16, and a connector 2 5 is installed inside the shell 16. The outer side of the connector 2 5 is provided with an installation groove 51, and a fixing ring 52 is placed on the installation groove 51. The main body 4 and the fixing ring 52 are provided with a threaded hole 53 that communicates with each other. A screw 54 is threaded into the threaded hole 53. The fixing ring 52 supports the connector 2 5, and then the screw 54 fixes the fixing ring 52, the shell 16 and the connector 2 5 together. One end of the inner tube 2 is fixedly connected to the connector 2 5 and communicates with the inside of the shell 16 to ensure that water can flow from the inside of the shell 16 to the inner tube 2. A cold water pipe 41 and a hot water pipe 42 that communicate with the inner tube 2 are fixedly connected inside the shell 16, realizing the mixing function of cold water and hot water. Users can precisely control the water temperature by adjusting the flow ratio of cold and hot water. A threaded fitting 6 is threadedly connected to the bottom of the shell 16, and the faucet is fixed to the washbasin by the threaded fitting 6.

A magnet 94 is fixedly connected between the housing 91 and the connector 92. By attracting the magnet 94 through the magnetic suction component 32, the nozzle 7 can be easily attracted to the fixing rod 31 without shaking. Preferably, the magnetic suction component 32 is wrapped with a plastic shell 16. This shell 16 can not only appropriately reduce the magnetic force and prevent the nozzle 7 from being attracted too tightly, making it easy for the user to pull it out, but also plays a waterproof role, preventing the magnetic suction component 32 from being corroded by prolonged contact with water. This not only improves the convenience of use, but also extends the service life of the product.

[0030] To improve the overall sealing performance of this utility model, at least one inner groove 21 is provided at both ends of the inner tube 2, and a sealing ring 8 is provided on each inner groove 21; the connector 2 5 is provided with an inner groove 55 below the mounting groove 51, and a sealing ring 8 is provided on the inner groove 55.
