Description

Technical Field

[0001] This utility model relates to the field of water pipe connection technology, specifically a snap-fit ​​leak-proof HPTE water supply pipe connection component. Background Technology

[0002] HDPE water supply pipes are made of high-density polyethylene (HDPE). HDPE water supply pipes are a substitute for traditional steel pipes and polyvinyl chloride drinking water pipes, and have excellent performance and a wide range of applications.

[0003] Traditional pipeline filtration devices mostly use fixed filter screens, which have limited filtration area and are prone to clogging by impurities. They require frequent disassembly and cleaning, resulting in high maintenance costs. To address this, we propose a snap-fit ​​leak-proof HPTE water supply pipeline connection component. Utility Model Content

[0004] The purpose of this utility model is to provide a snap-fit, leak-proof HPTE water supply pipe connection component.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a snap-fit ​​leak-proof HPTE water supply pipe connection assembly, comprising a first connecting pipe and a second connecting pipe, wherein a snap-fit ​​assembly is provided inside the first connecting pipe and a filter assembly is provided inside the second connecting pipe;

[0006] The snap-fit ​​assembly includes a snap-fit ​​plate, a threaded sleeve, a limiting groove, a top plate, and a mounting groove. The mounting groove is formed on the side of the first connecting pipe, the limiting groove is formed on the side of the second connecting pipe, the side of the snap-fit ​​plate is rotatably connected to the inner wall of the mounting groove, the side of the snap-fit ​​plate is snapped into the inner wall of the limiting groove, the inner wall of the threaded sleeve is threadedly connected to the side of the second connecting pipe, and the side of the top plate is slidably connected to the inner wall of the mounting groove.

[0007] The filter assembly includes a sealing plate, a filter plate, and a storage chamber. The storage chamber is formed on the inner wall of the second connecting pipe. The side of the sealing plate is rotatably connected to the inner wall of the storage chamber, and the side of the filter plate is connected to the inner wall of the second connecting pipe.

[0008] As a further embodiment of this utility model: a spring is connected inside the mounting groove, one end of the spring is connected to the side of the top plate, and the side of the top plate abuts against the side of the snap-fit ​​plate.

[0009] As a further embodiment of this utility model: the filter plate is configured in a conical shape, and the storage cavity is located on the side of the filter plate.

[0010] As a further embodiment of this utility model: the first connecting pipe is connected to one end of the second connecting pipe, and the water flow direction in the first connecting pipe and the second connecting pipe is from the second connecting pipe to the first connecting pipe.

[0011] As a further embodiment of this utility model: the shape of the side of the snap-fit ​​plate matches the shape of the inner wall of the limiting groove, and the shape of the side of the sealing plate matches the shape of the side of the second connecting pipe.

[0012] As a further embodiment of this utility model: the inner wall of the threaded sleeve is slidably connected to the side of the snap-fit ​​plate, and the inner wall of the threaded sleeve is threadedly connected to the side of the sealing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0014] 1. This utility model expands the filtration area through a conical filter plate, which can effectively intercept impurities in the water flow and ensure water quality. The storage chamber is set on the side of the filter plate, which facilitates the deposition and collection of impurities, and avoids impurities clogging the pipes or affecting the smoothness of the water flow. The sealing plate is rotatably connected to the inner wall of the storage chamber. When cleaning impurities, the storage chamber can be opened by simply rotating the sealing plate. There is no need to disassemble the entire pipe assembly, which reduces the difficulty and cost of maintenance.

[0015] 2. This utility model uses the shape of the snap-fit ​​plate matching the inner wall of the limiting groove. By rotating the threaded sleeve, the snap-fit ​​plate is pushed into the limiting groove to form a mechanical interlocking fixation. Pipe connection can be completed quickly without complicated tools, improving installation efficiency. The spring pushes the top plate to abut against the snap-fit ​​plate, which, together with the tightening effect of the threaded sleeve, makes the connection structure more stable and prevents the pipe from loosening due to water flow impact or vibration. The tight snap-fit ​​between the snap-fit ​​plate and the limiting groove can effectively fill the gap at the connection, and combined with the squeezing effect of the threaded sleeve, it reduces the water leakage path.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0024] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see the appendix Figure 1 - Appendix Figure 5 The present invention relates to a snap-fit ​​leak-proof HPTE water supply pipe connection assembly, comprising a first connecting pipe 1 and a second connecting pipe 2, wherein a snap-fit ​​assembly 3 is provided inside the first connecting pipe 1 and a filter assembly 4 is provided inside the second connecting pipe 2.

[0026] In embodiment 1, the snap-fit ​​assembly 3 includes a snap-fit ​​plate 31, a threaded sleeve 32, a limiting groove 33, a top plate 34, and a mounting groove 36. The mounting groove 36 is opened on the side of the first connecting pipe 1, and the limiting groove 33 is opened on the side of the second connecting pipe 2. The side of the snap-fit ​​plate 31 is rotatably connected to the inner wall of the mounting groove 36, and the side of the snap-fit ​​plate 31 is snapped into the inner wall of the limiting groove 33. The inner wall of the threaded sleeve 32 is threadedly connected to the side of the second connecting pipe 2. The side of the top plate 34 is slidably connected to the inner wall of the mounting groove 36. A spring 35 is connected inside the mounting groove 36, and one end of the spring 35 is connected to the side of the top plate 34. The side of the top plate 34 abuts against the side of the snap-fit ​​plate 31. The filter plate 42 is set in a conical shape, and the storage cavity 43 is located on the side of the filter plate 42. The shape of the side of the snap-fit ​​plate 31 matches the shape of the inner wall of the limiting groove 33. The inner wall of the threaded sleeve 32 is slidably connected to the side of the snap-fit ​​plate 31.

[0027] Specifically, in the initial state when the threaded sleeve 32 is not rotated, the spring 35 pushes the top plate 34, causing the front end of the snap-fit ​​plate 31 to slightly protrude from the mounting groove 36 and align with the entrance of the limiting groove 33. The threaded sleeve 32 is rotated clockwise, and its inner wall thread engages with the second connecting pipe 2. The sleeve moves axially towards the first connecting pipe 1, and the protrusion on the inner wall of the sleeve contacts the back of the snap-fit ​​plate 31, applying a radial thrust. This forces the snap-fit ​​plate 31 to rotate around the pivot, and its front end snaps into the limiting groove 33. The spring 35 is compressed and stores energy, providing a continuous clamping force to ensure that the snap-fit ​​plate 31 is tightly fitted with the inner wall of the limiting groove 33, thus locking the threaded sleeve 32. After the threaded sleeve 32 is tightened, the snap-fit ​​plate 31 is fully embedded in the limiting groove 33, forming a triple locking structure of "mechanical engagement + spring clamping + thread fastening" to prevent axial loosening.

[0028] In embodiment 2, the filter assembly 4 includes a sealing plate 41, a filter plate 42, and a storage chamber 43. The storage chamber 43 is opened on the inner wall of the second connecting pipe 2. The side of the sealing plate 41 is rotatably connected to the inner wall of the storage chamber 43. The side of the filter plate 42 is connected to the inner wall of the second connecting pipe 2. One end of the first connecting pipe 1 is connected to one end of the second connecting pipe 2. The water flow direction in the first connecting pipe 1 and the second connecting pipe 2 is from the second connecting pipe 2 to the first connecting pipe 1. The shape of the side of the sealing plate 41 matches the shape of the side of the second connecting pipe 2. The inner wall of the threaded sleeve 32 is threadedly connected to the side of the sealing plate 41.

[0029] Specifically, water enters through the inlet of the second connecting pipe 2. When it passes through the conical filter plate 42, impurities are trapped by the filter holes. Clean water flows through the filter holes toward the cone tip and enters the first connecting pipe 1. The conical design causes the water flow to form a diffusion flow on the surface of the filter plate 42, expanding the filtration area and reducing the probability of impurities clogging the filter holes. The trapped impurities (such as mud, rust, and suspended solids) slide down the surface of the filter plate 42 under the impact of the water flow and settle at the bottom of the storage chamber 43. Gravity is used to separate the impurities from the water flow. The sealing plate 41 is rotated counterclockwise to open the opening of the storage chamber 43 around the pivot. Impurities in the chamber are removed by flushing or suction. After cleaning, the sealing plate 41 is rotated back to its original position without disassembling the pipe.

[0030] Working principle:

[0031] First, insert the second connecting pipe 2 into the first connecting pipe 1, so that the limiting groove 33 on the side of the second connecting pipe 2 is aligned with the snap-fit ​​plate 31 in the mounting groove 36 of the first connecting pipe 1. At this time, under the action of the spring 35 (the spring 35 in the mounting groove 36 abuts against the top plate 34, and the top plate 34 pushes the snap-fit ​​plate 31), the side of the snap-fit ​​plate 31 contacts the inner wall of the limiting groove 33. Rotate the threaded sleeve 32 so that its inner wall is threadedly connected to the side of the second connecting pipe 2. During the rotation of the threaded sleeve 32, the inner wall pushes the snap-fit ​​plate 31 to rotate around the inner wall of the mounting groove 36. The snap-fit ​​plate 31 gradually snaps into the limiting groove 33, realizing the engagement and fixation of the first connecting pipe 1 and the second connecting pipe 2.

[0032] The side of the snap-fit ​​plate 31 matches the shape of the inner wall of the limiting groove 33, forming a tight snap-fit. Combined with the fastening effect of the threaded sleeve 32, it can effectively prevent water leakage at the connection. At the same time, the side of the sealing plate 41 matches the shape of the side of the second connecting pipe 2, further enhancing the sealing effect. When the water flows from the second connecting pipe 2 to the first connecting pipe 1, it first passes through the filter plate 42. Impurities in the water are intercepted by the filter plate 42. The clean water flows through the filter plate 42 and enters the first connecting pipe 1. The intercepted impurities are impacted and accumulated in the storage cavity 43 on the side of the filter plate 42. The sealing plate 41 is rotatably connected to the inner wall of the storage cavity 43. When it is necessary to clean the impurities, the sealing plate 41 can be rotated to open the storage cavity 43 for easy discharge of impurities. At this point, the entire process is completed.
