Description

Technical Field

[0001] This utility model relates to the field of water pipe connection technology, specifically a quick-connect sealing device for drain pipes. Background Technology

[0002] In daily life, the bottom drainage of facilities such as washbasins and sinks usually requires connecting the drain pipe to the ground drain pipe. This process usually involves inserting the rigid part of the drain pipe at the bottom into the drain pipe.

[0003] Chinese patent CN109723109A discloses an odor-proof sealing connector for a drain pipe, comprising an upper connecting pipe and a lower connecting pipe. The upper connecting pipe consists of a main pipe body, a threaded pipe, a washer, a rubber gasket, and a tightening cap. The main pipe body consists of a thicker pipe connected to a thinner pipe at its upper end. The threaded pipe is connected to the upper part of the thicker section of the main pipe body. The washer is fitted onto the thinner section of the main pipe body. The tightening cap is threaded onto the threaded pipe. The rubber gasket is fitted onto the thinner section of the main pipe body and contacts the tightening cap. The lower connecting pipe has a thicker pipe and a thinner pipe, with the thinner section of the lower connecting pipe inserted into the main pipe body of the upper connecting pipe. The lower connecting pipe is connected to the drain pipe via sealant, while the thinner section of the main pipe body of the upper connecting pipe is for the insertion of a sink drain pipe. Tightening the tightening cap compresses the rubber gasket, pressing the end of the sink drain pipe tightly.

[0004] The above technical solution has at least the following defects: the lower connecting pipe is connected to the drain pipe with sealant, but the upper connecting pipe and the lower connecting pipe are only connected by plugging, and the airtightness between the two is not good, which directly leads to poor odor prevention effect at the connection between the drain pipe and the drain pipe. If sealant is used to connect the two, it will be difficult to disassemble and clean the upper connecting pipe and the lower connecting pipe later, which is inconvenient for maintenance. This connection method needs to be improved. Utility Model Content

[0026] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of this utility model, and should not be construed as limiting the utility model.

[0027] Example 1: As Figure 1-4 As shown, this embodiment discloses a quick-connect sealing device for drain pipes, comprising two pipe bodies, one of which is connected to a drain pipe 1, and the other pipe body is connected to a drain pipe 6. The two pipe bodies are detachably connected by a first sealing assembly. The first sealing assembly includes a locking block 7 connected to one of the pipe bodies, a locking groove 8 connected to the other pipe body, and a first sealing ring 9 disposed between the two pipe bodies.

[0028] Specifically, in this embodiment, the pipe body connected to the drain pipe 1 is the upper pipe body 3, and the pipe body connected to the drain pipe 6 is the lower pipe body 4. A locking block 7 is disposed on the outer wall of the upper pipe body 3, and a locking groove 8 is disposed on the inner wall of the lower pipe body 4. An annular groove for placing the first sealing ring 9 is provided on the outer wall of the upper pipe body 3. The upper pipe body 3 can be fitted into the lower pipe body 4, and the connection between the two pipe bodies is achieved through the cooperation of the locking groove 8 and the locking block 7. The first sealing ring 9 is deformed by compression between the two pipe bodies, thereby achieving a sealed connection between the upper pipe body 3 and the lower pipe body 4. The locking groove 8 includes a slide 82, a locking opening 81 disposed at the top of the slide 82, and a positioning groove 83 disposed at the bottom of the slide 82. The locking block 7 can slide into or out of the positioning groove 83 through the locking opening 81 and the slide 82, realizing the assembly and disassembly of the upper pipe body 3 and the lower pipe body 4.

[0029] The upper pipe body 3 is fitted with a floor drain core 12 by snap-fit ​​or threaded connection. The floor drain core 12 is a conventional odor-proof floor drain core. The floor drain core 12 is used to prevent odors and sewage in the drain pipe 6 from overflowing into the drain pipe 1.

[0030] In this embodiment, the slide 82 is inclined, and the slide 82 is equipped with an inlet ramp 821 for the locking block 7 to slide into the positioning groove 83 and an outlet ramp 822 for the locking block 7 to slide out of the positioning groove 83. The locking block 7 is provided with a guide ramp 71 that matches the inlet ramp 821. When the locking block 7 slides into the slide 82 through the locking slot 81, as the upper tube 3 rotates, the guide ramp 71 and the outlet ramp 822 fit tightly together. Under the guidance of the inlet ramp 821, the locking block 7 can quickly enter the positioning groove 83 to achieve the limiting function. When the locking block 7 slides out of the slide 82, the outlet ramp 822 ensures that the locking block 7 can slide out quickly and smoothly through the locking slot 81. In this embodiment, there are three sets of locking blocks 7 and locking slots 8, which are circumferentially distributed between the upper tube 3 and the lower tube 4.

[0031] To achieve a seal between the upper pipe body 3 and the drain pipe 1, the upper pipe body 3 and the drain pipe 1 are detachably connected by a second sealing assembly. This second sealing assembly includes a first threaded pipe 2 threadedly connected to the upper pipe body 3, and a sealing sleeve 10 disposed between the first threaded pipe 2 and the upper pipe body 3. The inner wall of the sealing sleeve 10 is tightly fitted to the outer wall of the drain pipe 1. The sealing sleeve 10 is made of rubber, and the upper pipe body 3 is positioned relative to the bottom of the sealing sleeve 10. Therefore, when the first threaded pipe 2 is rotated, the sealing sleeve 10 deforms under its pressure, ensuring a tight fit between the sealing sleeve 10 and the drain pipe 1, thus achieving an effective seal between the upper pipe body 3 and the drain pipe 1.

[0032] To achieve a seal between the lower pipe body 4 and the drain pipe 6, the lower pipe body 4 and the drain pipe 6 are detachably connected via a third sealing assembly. The third sealing assembly includes a second threaded pipe 5 threaded to the lower pipe body 4 and a second sealing ring 11 disposed between the second threaded pipe 5 and the lower pipe body 4. The second sealing ring 11 is in contact with the outer wall of the drain pipe 6. When the second threaded pipe 5 is rotated, under its pressure, the second sealing ring 11 is pressed, thereby ensuring a tight seal between the second sealing ring 11 and the drain pipe 6, achieving an effective seal between the lower pipe body 4 and the drain pipe 6.

[0033] Installation Principle: First, the drain pipe 1 is connected to the upper pipe body 3 via the first threaded pipe 2 and the sealing sleeve 10. Then, the drain pipe 6 is connected to the upper pipe body 3 via the second threaded pipe 5 and the second sealing ring 11. Next, the upper pipe body 3 is inserted into the lower pipe body 4, allowing the locking block 7 to slide into the slide rail 82 through the locking slot 81. Subsequently, the upper pipe body 3 is rotated, causing the guide slope 71 of the locking block 7 to engage with the guide slope 821 of the slide rail 82. Under the action of the guide slope 821, the locking block 7 is engaged in the positioning groove 83. Then, the upper pipe body 3 is lifted, causing the locking block 7 to engage with the top of the positioning groove 83 (there is a certain friction between the first sealing ring 9 and the upper pipe body 3 and the lower pipe body 4 to prevent the upper pipe body 3 and the lower pipe body 4 from moving due to gravity). Therefore, the right side of the positioning groove 83 limits the locking block 7, preventing it from sliding out of the positioning groove 83.

[0034] When it is necessary to separate the upper tube body 3 and the lower tube body 4, simply press down on the upper tube body 3 to move the locking block 7 down within the positioning groove 83, disengaging it from its limiting position. Then, rotate the lower tube body 4 in the opposite direction to make the locking block 7 engage with the guide slope 822. Under the action of the guide slope 822, the locking block 7 disengages from the slide rail 82, achieving the separation of the upper tube body 3 and the lower tube body 4. This design not only provides a stable connection and excellent sealing effect, but also makes the disassembly and assembly process more convenient and efficient.

[0035] Example 2: Figure 5 , Figure 6 As shown, the difference between this embodiment and Embodiment 1 lies in the design of the second sealing component. In this embodiment, the third sealing component includes an adhesive layer disposed between the lower pipe body 4 and the drain pipe 6. The specific operation steps are as follows: first, the adhesive layer is evenly applied to the outer wall of the drain pipe 6, and then the lower pipe body 4 is fitted onto the drain pipe 1, using the adhesive layer to fix the two together. This method is not only simple to operate, but also significantly reduces costs.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
