Description

Technical Field

[0001] This utility model belongs to the field of washing machine technology, and in particular relates to a washing machine base tube structure. Background Technology

[0002] Household washing machine drain pipes are typically connected to the washing machine's drain outlet via fixed pipe fittings, such as integrated clamps or connections using flexible corrugated pipes. However, in actual installation environments, differences in drain outlet location, floor slope, or spatial layout often necessitate flexible adjustments to the drain pipe's water flow direction. To address this, additional flexible drain pipes or bent fittings are often used, increasing space requirements and increasing the risk of leaks, damaging the pipe's seal, affecting the washing machine's normal operation, and creating a risk of further leaks.

[0003] Therefore, the market urgently needs a pipe fitting structure that can provide a stable connection while allowing users to freely and flexibly adjust the drainage direction as needed after installation. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a washing machine base pipe structure that allows the drain pipe to rotate infinitely after installation to adapt to different installation environments, while ensuring that the connection is reliably sealed and firmly fixed.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: it includes a drain pipe and a fastening fitting, and also includes an L-shaped bend. The fastening fitting includes a pair of spliced ​​clamping parts and a threaded fastener. After the two spliced ​​clamping parts are assembled, they cover the outside of one end of the L-shaped bend. The threaded fastener is sleeved on the outside of the spliced ​​clamping parts. The end of the drain pipe is inserted into the inside of the end of the L-shaped bend.

[0006] Furthermore, the two splicing clamping components include a cylindrical body, one end of which protrudes outward to form an annular clamping body. The outer surface of the cylindrical body is provided with threads that engage with the inner wall of the threaded fastener. The threaded fastener has an overall structure in the shape of a hexagonal nut and cooperates with the annular clamping body to clamp the outer wall of the washing machine.

[0007] Furthermore, one end of the L-shaped bend protrudes outward to form an annular limiting body, which is engaged at the inner end of the splicing clamp and the end faces are connected. The other end of the annular limiting body is abutted by the end of the drain pipe and the end faces are connected.

[0008] Furthermore, the outer surface of the drain pipe is divided into two sections with different outer diameters. The section with the smaller outer diameter is inserted into the inner side of the L-shaped bend end and abuts against the end face of the annular limiting body through the stepped surface formed at the junction of the outer diameters.

[0009] Furthermore, an annular groove is provided on the outer side of the section with a smaller outer diameter of the drain pipe, and an annular groove is also provided on the inner wall of the end of the L-shaped bend. A sealing slip ring is sandwiched in the two annular grooves.

[0010] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects: 1. In this utility model, the L-shaped bend is covered by two splicing clamping parts but is not circumferentially locked. Users only need to loosen the threaded fasteners to easily drive the L-shaped bend to rotate 360 ​​degrees, achieving stepless adjustment and accurately adapting to various complex installation environments and drainage outlet positions. 2. In this utility model, two spliced ​​clamping parts are tightened by threaded fasteners, and at the same time, they form a uniform locking force with the annular clamping body to clamp the outer wall of the washing machine drain outlet, which effectively prevents loosening and falling off due to vibration or pulling during use, and ensures the reliability of long-term use. 3. In this utility model, the unique double-ring groove and sealing slip ring design constitute a reliable sealing system. The sealing slip ring is compressed between the drain pipe and the L-shaped bend, forming an effective radial seal to ensure that sewage leakage is prevented at any rotation angle. The sealing slip ring has both sealing and connection functions, tightly combining the drain pipe and the L-shaped bend into a modular unit that can rotate as a whole, simplifying the structure. Axial positioning is achieved through the stepped surface and the annular limiting body, while radial fixing is achieved through the sealing slip ring. The structure is compact, the assembly process is clear, and production and installation are convenient. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Combination Figures 1 to 4 The washing machine base pipe structure shown includes a drain pipe 1 and a fastening pipe 2, as well as an L-shaped bend 3. The fastening pipe 2 includes a pair of splicing clamping parts 21 and a threaded fastener 22. After the two splicing clamping parts 21 are assembled, they cover the outside of one end of the L-shaped bend 3. The threaded fastener 22 is sleeved on the outside of the splicing clamping parts 21. The end of the drain pipe 1 is inserted into the inside of the end of the L-shaped bend 3.

[0015] Among them, the two splicing clamping parts 21 include a cylindrical body 211, one end of the cylindrical body 211 protrudes outward to form an annular clamping body 212, the outer surface of the cylindrical body 211 is provided with threads and engages with the inner wall of the threaded fastener 22, the threaded fastener 22 has an overall structure in the shape of a hexagonal nut, and it cooperates with the annular clamping body 212 to clamp the outer wall of the washing machine.

[0016] One end of the L-shaped bend 3 protrudes outward to form an annular limiting body 31. The annular limiting body 31 is locked at the inner end of the splicing clamping part 21 and the end faces are connected. The other end of the annular limiting body 31 is abutted by the end of the drain pipe 1 and the end faces are connected.

[0017] The outer surface of the drain pipe 1 is divided into two sections with different outer diameters. The section with the smaller outer diameter of the drain pipe 1 is inserted into the inner side of the end of the L-shaped bend 3 and abuts against the end face of the annular limiting body 31 through the stepped surface formed at the junction of the outer diameters.

[0018] An annular groove 11 is provided on the outer side of the section with a smaller outer diameter of the drain pipe 1, and an annular groove 11 is also provided on the inner wall of the end of the L-shaped bend 3. A sealing slip ring 12 is sandwiched in the two annular grooves 11.

[0019] Working principle: During installation, the L-shaped bend 3 with the annular limiting body 31 is first placed into the semi-circular groove of a splicing clamping piece 21. Then, another splicing clamping piece 21 is placed on top, so that the two splicing clamping pieces 21 are aligned to form a complete cylindrical body 211, which covers that end of the L-shaped bend 3. At this time, the annular limiting body 31 on the L-shaped bend 3 is clamped at the inner end face of the two splicing clamping pieces 21, restricting the axial movement of the L-shaped bend 3, but the L-shaped bend 3 can still rotate freely inside it. Then, the assembly is placed on the outer wall of the washing machine drain outlet, and the threaded fastener 22 is screwed onto the external thread of the splicing clamp 21. The threaded fastener 22 is tightened with a tool, which tightens inward, forcing the two splicing clamps 21 to fit tightly together. The annular clamp 212 and the threaded fastener 22 are firmly clamped on both sides of the washing machine outer shell. Next, a sealing slip ring 12, typically an O-ring or a flexible plastic ring, is pre-placed in the annular groove 11 of the section with the smaller outer diameter at the end of the drain pipe 1. Then, the end of the drain pipe 1 is inserted into the L-shaped bend 3. After insertion, the stepped surface of the drain pipe 1 abuts against the annular limiting body 31 of the L-shaped bend 3, and cooperates with the inner end face of the splicing clamping part 21 to complete axial positioning. The sealing slip ring 12 is compressed within the space formed by the annular groove 11 of the drain pipe 1 and the L-shaped bend 3, achieving radial sealing and fastening, connecting the drain pipe 1 and the L-shaped bend 3 into a whole, without affecting the rotation of the L-shaped bend 3.
