Description

Technical Field

[0001] The utility model relates to the technical field of joints, in particular to a water pipe joint. Background Art

[0002] Water pipe joints are important parts for connecting water pipes. Their design and selection are crucial to ensure the normal operation of the water system. According to different usage methods, water pipe joints can be divided into various types such as external thread segment connection type, ferrule type, self-fixing type, etc. These joints are not only used to extend the length of water pipes, change the direction of water flow or connect multiple water pipes, but also play a key role in home decoration, industrial water supply systems and engine cooling systems.

[0003] When the existing water pipe joint is connected to the water outlet pipe, it is necessary to wrap raw tape around the water pipe joint to increase the sealing of the connection between the water pipe joint and the water outlet pipe. Although wrapping the raw tape can increase the sealing, it will also increase the difficulty of installation. Although reducing the number of raw tape wraps can reduce the difficulty of installation, it cannot guarantee the sealing of the connection, causing inconvenience to daily use. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology, the utility model proposes a water pipe joint.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A water pipe joint comprises a main body, wherein a water passage is formed in the main body, one end of the main body is formed with a first thread segment, and the other end of the main body is formed with a second thread segment, and the outer diameter of the first thread segment is smaller than the outer diameter of the second thread segment.

[0007] Preferably, the outer diameter of the second thread segment is 1.1-1.2 times the outer diameter of the first thread segment. Through the above improvements, the outer diameter of the first thread segment is only slightly smaller than the second thread segment in the overall structure, and the outer diameter of the second thread segment is 1.1-1.2 times the outer diameter of the first thread segment. The first thread segment needs to be connected to the water outlet pipe, so that the first thread segment needs to withstand greater water pressure, so more raw tape needs to be wound. When the raw tape is wound on the first thread segment and is close to the outer diameter of the second thread segment, it not only ensures the sealing between the first thread segment and the water outlet pipe, but also does not cause difficulty in connecting the first thread segment to the water outlet pipe. Since the second thread segment is far away from the water delivery area relative to the first thread segment, when connected to the water pipe, there is no need to wind too much raw tape, so the outer diameter of the second thread segment is larger than the first thread segment, which not only ensures the sealing of the connection with the water pipe, but also has good sealing.

[0008] Preferably, a transition section is formed between the first thread section and the second thread section, and a fixing nut meshing with the first thread section is provided on the transition section. Through the above improvement, the reliability of the water pipe joint installation is improved by using the fixing nut to cooperate with the first thread section.

[0009] Preferably, an abutment platform is formed on the transition section, and the fixing nut abuts against the abutment platform to limit the fixing nut from moving toward the second threaded section. Through the above improvement, a foolproof effect is achieved to prevent the user from moving the fixing nut toward the second threaded section.

[0010] Preferably, the length of the first thread segment is greater than that of the second thread segment. Through the above improvements, since the first thread segment is closer to the water source, a longer connection distance is required to ensure sealing.

[0011] Preferably, the length of the first thread segment is 19-21 mm. Through the above improvements, the distance of the first thread segment inserted into the water outlet pipe is ensured to ensure sealing.

[0012] Preferably, the length of the second thread segment is 16-18 mm. Through the above improvements, the distance of the second thread segment connecting other water pipes is guaranteed to ensure sealing.

[0013] Preferably, the thickness of the fixing nut is 6-8 mm. Through the above improvements, not only the reliability of fixing the water pipe joint is improved, but also the distance of the first threaded section will not be occupied too much.

[0014] Preferably, a glue injection channel is formed in the main body, and a glue injection port connected to the injection channel is formed on the main body, and a plurality of glue outlet holes connected to the glue injection channel are formed on the first thread segment. Through the above improvement, the glue injection port can be used to inject sealant into the glue injection channel, and the sealant can be placed on the first thread segment through the glue outlet holes, thereby improving the sealing of the connection between the first thread segment and the water pipe.

[0015] Preferably, the main body has a plurality of injection channels, and the injection channels are arranged at equal intervals along the radial direction of the main body. Through the above improvement, sealant can be injected into the plurality of injection channels, so that sealant is present at multiple points in the first threaded section, thereby further improving the sealing performance of the connection with the water pipe.

[0016] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0017] By connecting the first thread segment to a water pipe close to a water source, the first thread segment needs to bear a greater water pressure, and the second thread segment is used to connect other water pipes to achieve connectivity of the entire water path. Since the first thread segment needs to bear a greater water pressure, it is necessary to ensure the sealing between the first thread segment and the water outlet pipe, so that the outer diameter of the first thread segment is set to be smaller than the outer diameter of the second thread segment, so that more raw tape can be wound around the first thread segment, thereby ensuring the sealing of the connection between the first thread segment and the water pipe, and not causing any inconvenience in installation due to winding the raw tape, thereby improving user convenience.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0026] like Figure 1-2As shown, a water pipe joint includes a main body 1, a water passage 2 is formed in the main body 1, a first thread segment 3 is formed at one end of the main body 1, and a second thread segment 4 is formed at the other end, and the outer diameter of the first thread segment 3 is smaller than the outer diameter of the second thread segment 4.

[0027] During the use of the water pipe joint, the first threaded section 3 is connected to a water pipe close to a water source, so that the first threaded section 3 needs to bear a larger water pressure, and the second threaded section 4 is used to connect other water pipes to achieve connectivity of the entire waterway.

[0028] Since the first thread segment 3 needs to bear a greater water pressure, it is necessary to ensure the sealing between the first thread segment 3 and the water outlet pipe. It is necessary to wind more raw tape on the first thread segment 3, so that the outer diameter of the first thread segment 3 is set to be smaller than the outer diameter of the second thread segment 4, so that the first thread segment 3 can be wound with more raw tape without causing inconvenience in installation, and the sealing of the connection between the first thread segment 3 and the water outlet pipe can be ensured.

[0029] Further explanation of the implementation of the first thread segment 3 and the second thread segment, wherein the outer diameter of the second thread segment 4 is 1.1-1.2 times the outer diameter of the first thread segment 3.

[0030] In the overall structure, the outer diameter of the first thread segment 3 is only slightly smaller than that of the second thread segment 4, and the outer diameter of the second thread segment 4 is 1.1-1.2 times that of the first thread segment 3. Since the first thread segment 3 needs to be connected to the water outlet pipe, the first thread segment 3 needs to withstand a greater water pressure, so more raw tape needs to be wound. When the raw tape is wound on the first thread segment 3 and is close to the outer diameter of the second thread segment 4, not only the sealing between the first thread segment 3 and the water outlet pipe is ensured, but also the connection between the first thread segment 3 and the water outlet pipe will not be difficult. Since the second thread segment 4 is far away from the water delivery area relative to the first thread segment 3, there is no need to wind too much raw tape when connecting to the water pipe, so that the outer diameter of the second thread segment 4 is larger than the first thread segment 3, which not only can ensure the sealing of the connection with the water pipe, but also has good sealing.

[0031] In addition, a transition section 6 is formed between the first thread section 3 and the second thread section 4, and a fixing nut 5 meshing with the first thread section 3 is provided on the transition section 6. When the first thread section 3 is connected to the water outlet pipe, the fixing nut 5 is used to cooperate with the first thread section 3 to improve the reliability of the installation of the water pipe joint.

[0032] Furthermore, an abutment platform 7 is formed on the transition section 6 , and the fixing nut 5 abuts against the abutment platform 7 to limit the fixing nut 5 from moving toward the second threaded section 4 , thereby preventing the user from moving the fixing nut 5 toward the second threaded section 4 .

[0033] Preferably, the length of the first thread segment 3 is greater than that of the second thread segment 4, because the first thread segment 3 is closer to the water source and needs to be connected over a longer distance to ensure sealing.

[0034] Preferably, the length of the first thread segment 3 is 19-21 mm, which ensures the distance of the first thread segment 3 inserted into the water outlet pipe to ensure sealing.

[0035] Preferably, the length of the second thread segment 4 is 16-18 mm, which ensures the distance for the second thread segment 4 to connect to other water pipes to ensure sealing.

[0036] Preferably, the thickness of the fixing nut 5 is 6-8 mm, which not only improves the reliability of fixing the water pipe joint, but also does not occupy too much distance of the first threaded section 3.

[0037] Embodiment 2

[0038] like Figures 3 to 5 As shown, the difference between this embodiment and the first embodiment is that a glue injection channel 101 is formed in the main body 1, and a glue injection port 102 connected to the injection channel is formed on the main body 1, and a plurality of glue outlet holes 103 connected to the injection channel are formed on the first threaded section 3.

[0039] In daily use, if water leakage occurs, the water pipe joint often needs to be disassembled, replaced or repaired, which makes it inconvenient to use. However, the water pipe joint in this embodiment can use the injection port 102 to inject sealant into the injection channel 101, and the sealant can be placed on the first threaded section 3 through the glue outlet hole 103, thereby filling the gap between the first threaded section 3 and the water pipe, thereby avoiding water leakage.

[0040] Furthermore, a plurality of injection channels 101 are formed in the main body 1 and are arranged at equal intervals along the radial direction of the main body 1. Sealant can be injected into the plurality of injection channels 101, so that sealant is present at multiple points in the first threaded section 3, further improving the sealing performance of the connection with the water pipe.

[0041] Preferably, the glue outlet holes 103 are arranged on the first threaded section 3 at intervals along the axial direction of the water pipe joint.

[0042] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
