Description

Technical Field

[0001] This application relates to the field of drain assembly technology, and in particular to a high-sealing, spring-loaded drain assembly. Background Technology

[0002] As an essential component of sanitary ware such as sinks and basins, the pop-up drain primarily controls the opening and closing of the drainage channel. It must also possess excellent sealing performance and structural stability to ensure ease of use and durability. Currently, pop-up drains on the market typically include core components such as a base, connecting pipe, pop-up inner core, top cover, and spring. Pressing the top cover activates the internal pop-up mechanism, thus opening and closing the drainage channel.

[0003] Existing pop-up drainers do not provide ideal sealing in actual use. They mostly use a single sealing structure, which is difficult to fully cover the gaps between components, making water leakage easy and affecting the user experience. Utility Model Content

[0004] The purpose of this application is to provide a high-sealing, spring-loaded drain assembly that has both high sealing and anti-loosening properties, thus solving the problems mentioned in the background art.

[0005] The high-sealing spring-loaded drainer provided in this application adopts the following technical solution: The high-sealing spring-loaded drainer includes a base and a connecting pipe installed inside the base. The inner wall of the connecting pipe is provided with a guide groove. A spring-loaded inner core is installed on the inner wall of the connecting pipe. A guide block is fixedly connected to the outer surface of the spring-loaded inner core. The guide block is slidably sleeved in the inner wall of the guide groove. A reserved through groove is provided at the top of the connecting pipe. The bottom end of the reserved through groove extends into the interior of the connecting pipe. An L-shaped sliding rod is hinged to the top of the reserved through groove. An inverted V-shaped sliding groove is provided inside the spring-loaded inner core. The bottom end of the L-shaped sliding rod is slidably sleeved in the inner wall of the inverted V-shaped sliding groove.

[0006] The inner core of the spring has a connecting groove, and a spring body is fixedly connected to the inner wall of the connecting groove. A spring connecting block is fixedly connected to the inner bottom wall of the connecting tube. The top of the spring body is fixedly connected to the outer surface of the spring connecting block. A top cover is provided on the top of the connecting tube. An installation groove is provided on the bottom of the top cover. A sealing cover is installed on the inner wall of the installation groove. A sealing ring is fixedly connected to the bottom of the top cover.

[0007] By adopting the above technical solution, the sliding cooperation of the guide groove and the guide block can effectively constrain the movement trajectory of the connecting pipe outside the spring-loaded inner core, preventing it from deviating or misaligning during sliding. The linkage between the L-shaped slide rod and the inverted V-shaped slide groove, combined with the elastic support of the spring body and the spring connecting block, ensures that the opening and closing action of the connecting pipe is smooth and continuous, and not easy to loosen. At the same time, the sealing cover is installed through the mounting groove, providing a stable installation carrier for the top sealing structure, initially blocking water flow from seeping into the joint gap, laying the foundation for the overall high sealing performance, and solving the problems of jamming action and unstable installation of the sealing structure in traditional spring-loaded drainers.

[0008] Preferably, the bottom end of the base is provided with a first internal thread, the bottom end of the bouncing inner core is provided with a first external thread, and the base is connected to the bottom thread of the bouncing inner core through the first internal thread and the first external thread.

[0009] By adopting the above technical solution, the base is connected to the first external thread of the spring-loaded inner core through the first internal thread, so that the two are tightly and firmly connected, effectively avoiding the loosening of the connection caused by water flow impact or frequent operation during long-term use of the drainer, and improving the stability of the overall structure.

[0010] Preferably, the top of the connecting pipe is provided with a second external thread, and the inner wall of the top cover is provided with a second internal thread. The top cover is connected to the top of the connecting pipe by the second external thread and the second internal thread.

[0011] By adopting the above technical solution, the top cover is fixed to the second external thread of the connecting pipe through the second internal thread, which not only realizes the convenient disassembly and assembly of the top cover and the connecting pipe, but also ensures the sealing of the two after connection, prevents water from leaking from the connection, and enhances the overall anti-loosening performance of the structure.

[0012] Preferably, the sealing cover is located between the base and the top cover.

[0013] By adopting the above technical solution, the sealing cover located between the base and the top cover can initially block water infiltration. Together with the sealing ring at the bottom of the top cover, it forms a double sealing protection, further improving the sealing performance of the device and reducing the risk of water leakage.

[0014] Preferably, the sealing cover is located above the sealing ring, and the sealing ring is located at the gap between the contact end of the base and the top cover.

[0015] By adopting the above technical solution, the sealing cover and the sealing ring are distributed in an upper and lower layer. The sealing ring can cover the contact gap between the base and the top cover. The sealing cover protects the sealing ring while enhancing the sealing effect, thereby blocking the water leakage path in all directions.

[0016] Preferably, the bottom of the base has a mesh channel for water passage.

[0017] By adopting the above technical solution, the mesh channel at the bottom of the base can not only ensure smooth water flow, but also perform preliminary filtration of larger debris in the water, preventing debris from entering the drain pipe and causing blockage, thus ensuring the smooth drainage of the drain device.

[0018] Preferably, a pressing block is fixedly connected to the top of the top cover.

[0019] By adopting the above technical solution, the pressing block at the top of the cover provides users with a convenient operating point, allowing users to control the on / off state of the device by pressing, thus improving the ease of use of the device.

[0020] Preferably, an anti-slip ring is fixedly connected to the outer surface of the base, and the anti-slip ring is located above the mesh channel.

[0021] By adopting the above technical solution, the anti-slip ring on the outer surface of the base can increase the friction between the device and the mounting surface, prevent the device from rotating or shifting after installation, and help improve the overall structure's anti-loosening effect.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This high-sealing pop-up drainer features a double-threaded fixation system. The base's first internal thread and the pop-up inner core's first external thread, along with the top cover's second internal thread and the connecting pipe's second external thread, form a double-threaded fixation. Combined with an anti-slip ring on the base's outer surface to increase friction with the mounting surface, this system firmly locks the components in place during water flow impact and frequent operation, effectively preventing loosening and displacement. The hierarchical distribution of the sealing cover and sealing ring, with the sealing ring filling the contact gap between the base and top cover and the sealing cover providing protection from above, creates a dual-structure working together to block water leakage paths and achieve a high-sealing effect. Guide grooves and guide blocks constrain the movement trajectory of the connecting pipe. The interlocking action of the L-shaped slide rod and the inverted V-shaped slide groove, along with the elastic support of the spring body and spring connecting block, ensures smooth and continuous opening and closing of the connecting pipe. Overall, this system guarantees stability and sealing while improving ease of operation and drainage, making it more practical. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0026] Example 1: High-sealing spring-loaded drain assembly, refer to Figure 1 , Figure 4 and Figure 5 The system includes a base 1 and a connecting pipe 2 installed inside the base 1. The inner wall of the connecting pipe 2 has a guide groove 3, and a spring-loaded inner core 4 is installed on the inner wall of the connecting pipe 2. The bottom end of the base 1 has a first internal thread 12, and the bottom end of the spring-loaded inner core 4 has a first external thread 13. The base 1 is connected to the bottom of the spring-loaded inner core 4 via the first internal thread 12 and the first external thread 13. The connection between the base 1 and the spring-loaded inner core 4 via the first internal thread 12 and the first external thread 13 ensures a tight and secure connection, effectively preventing water leakage. To prevent loosening of connections due to water flow impact or frequent operation during long-term use, and to improve the stability of the overall structure, a guide block 5 is fixedly connected to the outer surface of the spring-loaded inner core 4. The guide block 5 is slidably sleeved in the inner wall of the guide groove 3. A reserved through groove 6 is opened at the top of the connecting pipe 2. The bottom end of the reserved through groove 6 passes through the interior of the connecting pipe 2. An L-shaped slide rod 7 is hinged at the top of the reserved through groove 6. An inverted V-shaped slide groove 8 is opened inside the spring-loaded inner core 4. The bottom end of the L-shaped slide rod 7 is slidably sleeved in the inner wall of the inverted V-shaped slide groove 8.

[0027] It should be noted that the shape of the inverted V-shaped groove 8 is as follows: Figure 4 As shown, the top of the inverted V-shaped chute 8 is pointed, and the bottom of the inverted V-shaped chute 8 is open. When the L-shaped slide rod 7 is located at the pointed top of the inverted V-shaped chute 8, the device can drain water normally. However, when the L-shaped slide rod 7 is located at the opening at the bottom of the inverted V-shaped chute 8, the device is blocked and cannot drain water. This is because both the top and bottom openings of the inverted V-shaped chute 8 can limit the L-shaped slide rod 7, preventing it from moving further. Only when the connecting pipe 2 moves can the L-shaped slide rod 7 deflect, allowing it to move along the side groove of the inverted V-shaped chute 8. This allows the L-shaped slide rod 7 to switch between the top and bottom openings of the inverted V-shaped chute 8, thus achieving the opening and closing effect.

[0028] Reference Figure 3 , Figure 4 and Figure 5 The inner core 4 has a connecting groove 9 inside, and a spring body 11 is fixedly connected to the inner wall of the connecting groove 9. A spring connecting block 10 is fixedly connected to the inner bottom wall of the connecting tube 2. The top of the spring body 11 is fixedly connected to the outer surface of the spring connecting block 10. The top of the connecting tube 2 is provided with a top cover 14. The top of the connecting tube 2 has a second external thread 15. The inner wall of the top cover 14 has a second internal thread 16. The top cover 14 is threadedly connected to the top of the connecting tube 2 through the second external thread 15 and the second internal thread 16. The top cover 14 is threadedly fixed to the second external thread 15 of the connecting tube 2 through the second internal thread 16. This not only realizes the convenient disassembly and assembly of the top cover 14 and the connecting tube 2, but also ensures the sealing after the connection between the two, preventing water leakage from the connection point, and enhancing the overall anti-loosening performance of the structure. The bottom of the top cover 14 has an installation groove 17. A sealing cover 18 is installed on the inner wall of the installation groove 17.

[0029] Example 2: High-sealing spring-loaded drain assembly, refer to Figure 1 , Figure 2 and Figure 3 Based on the same concept as Embodiment 1 above, this embodiment proposes a sealing cover 18 located between the base 1 and the top cover 14. A sealing ring 19 is fixedly connected to the bottom end of the top cover 14. The sealing cover 18 located between the base 1 and the top cover 14 can initially block water seepage. Together with the sealing ring 19 at the bottom end of the top cover 14, it forms a double sealing protection, further improving the sealing performance of the device and reducing the risk of leakage. The sealing cover 18 is located above the sealing ring 19, which is located at the gap between the contact ends of the base 1 and the top cover 14. The sealing cover 18 and the sealing ring 19 are distributed in a hierarchical manner. The sealing ring 19 can cover the contact gap between the base 1 and the top cover 14. The sealing cover 18 protects the sealing ring 19 while enhancing the sealing effect, achieving all-round blocking of the water seepage path. The bottom of the base 1 has a mesh channel 20 for water flow. The mesh channel 20 at the bottom of the base 1 can not only ensure smooth water flow, but also perform preliminary filtration of larger debris in the water to prevent debris from entering the drain pipe and causing blockage, thus ensuring the smooth drainage of the drain. The top of the top cover 14 is fixedly connected to a pressing block 21, which provides a convenient operating point for the user to control the on / off state of the device by pressing, thus improving the ease of use of the device. The outer surface of the base 1 is fixedly connected to an anti-slip ring 22, which is located above the mesh channel 20. The anti-slip ring 22 on the outer surface of the base 1 can increase the friction between the device and the mounting surface, preventing the drain from rotating or shifting after installation, and helping to improve the anti-loosening effect of the overall structure.

[0030] The implementation principle of this embodiment is as follows: the base 1 is directly installed in the drain tank and remains fixed. The spring-loaded inner core 4 is threadedly connected to the first internal thread 12 at the bottom of the base 1 via the first external thread 13, and is thus simultaneously fixed. The anti-slip ring 22 on the outer surface of the base 1 is tightly fitted to the mounting surface, further increasing the friction with the mounting surface and preventing the device from rotating or shifting during use. The top cover 14 is installed on the top of the connecting pipe 2 via the second external thread 15 and the second internal thread 16, providing a stable foundation for subsequent actions. The user triggers the opening and closing action by pressing the pressing block 21 at the top of the top cover 14. The top cover 14 is connected to the top of the connecting pipe 2 via the second internal thread 16 on the inner wall. The second external thread 15 of the part is fixedly connected, and the pressing force is directly transmitted to the connecting tube 2, causing the connecting tube 2 to move up and down outside the fixed spring-loaded inner core 4. During this process, the guide groove 3 opened in the inner wall of the connecting tube 2 and the guide block 5 fixed on the outer surface of the spring-loaded inner core 4 form a sliding fit, which precisely constrains the movement trajectory of the connecting tube 2 and prevents it from deviating or misaligning during movement. At the same time, an L-shaped sliding rod 7 is fixed in the through groove 6 reserved at the top of the connecting tube 2. Its bottom end is slidably sleeved in the inverted V-shaped sliding groove 8 inside the spring-loaded inner core 4. As the connecting tube 2 moves up and down, the L-shaped sliding rod 7 slides along the inverted V-shaped sliding groove 8 and forms a linkage, while the connecting groove 9 inside the spring-loaded inner core 4 is fixed The spring body 11, with its top end fixedly connected to the spring connecting block 10 on the inner bottom wall of the connecting pipe 2, will elastically expand and contract with the movement of the connecting pipe 2, thereby realizing the automatic reset of the connecting pipe 2. When the pressing block 21 is pressed, it causes the connecting pipe 2 to move downward. After releasing, the spring body 11 rebounds and causes the connecting pipe 2 to move upward. At this time, the drainage channel is in the open state. When the pressing block 21 is pressed again, the L-shaped slide rod 7 will move along the inverted V-shaped slide groove 8 and lock into the downward opening of the inverted V-shaped slide groove 8. At this time, the drainage channel is in the closed state. When the device is in the closed state, the sealing cover 18 in the mounting groove 17 at the bottom of the top cover 14 is located between the base 1 and the top cover 14 and is sealed. The bottom surface of the cover 18 abuts against the upper surface of the base 1, and the sealing ring 19 below fills the contact gap between the base 1 and the top cover 14. The sealing cover 18 forms a protective layer above the sealing ring 19. The double structure works together to block the water leakage path. When the device is in the open state, the connecting pipe 2 and the top cover 14 move upward, and the bottom surface of the sealing cover 18 does not contact the upper surface of the top cover 14. At the same time, the sealing ring 19 will not fill the contact gap between the base 1 and the top cover 14. This allows the drainage channel to be unobstructed, and the water flows out through the mesh channel 20 at the bottom of the base 1. The mesh channel 20 also performs preliminary filtration of larger impurities in the water to prevent impurities from entering the drain pipe and causing blockage.
