Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a new type of quick-connect fitting for a water purifier faucet. Background Technology

[0002] Quick-connect fittings for water purifiers are core components for connecting water purification equipment pipelines. They enable rapid installation through snap-fit ​​or quick-plug design, allowing for a sealed connection without tools.

[0003] Chinese patent discloses a quick-connect fitting for explosion-proof pipes in water heaters (authorization announcement number CN215674147U). This patented technology allows for quick assembly via threads while ensuring a tight seal after assembly. However, it is difficult to disassemble, has a complex structure, and is not easy to use. Therefore, this utility model provides a novel quick-connect fitting for water purifier faucets to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of quick-connect fitting for water purifier faucets to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel quick-connect fitting for a water purifier faucet includes a pipe body with an externally threaded interface at the upper end and a connector at the lower end. A snap-fit ​​ring is inserted into the connector, and a pressing element is slidably connected to the inner side of the snap-fit ​​ring. A sealing ring is placed on the inner side of the upper end of the pressing element. Several outwardly opening claws are located on the upper part of the pressing element, and a triangular-section clip is located at the upper end of each claw. A snap-fit ​​strip is fixed to the inner side of the clip, and the sealing ring is placed above the snap-fit ​​strip. A connector groove is fixed to the inner side of the upper end of the connector, and a sealing ring is fixed to the outer side of the connector groove. Several protrusions are fixed to the outer side of the snap-fit ​​ring, and the protrusions have a triangular cross-section for easy snap-fit ​​at the connector.

[0007] Preferably, the outer center of the card has a recessed groove to reduce material consumption.

[0008] Preferably, a guide flange is fixed on the inner side of the insertion groove, and the outer side of the guide flange is arc-shaped to guide the insertion of the pipe.

[0009] Preferably, the sealing ring has an L-shaped cross-section and is snapped onto the inner stepped surface of the insertion tube.

[0010] Preferably, the outer side of the pipe body is corrugated, which improves the elasticity and torsional force of the pipe body and facilitates installation.

[0011] Preferably, the upper end of the claw is located outside the sealing ring. When the claw moves downward, the inner side of the upper end of the claw squeezes the sealing ring, increasing the sealing consumption.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model uses a plug-in connector for quick connection and employs a sealing ring and sealing ring for double sealing to improve the pipe's sealing performance. In use, after inserting the pipe into the bottom of the plug-in connector, pull the pipe out downwards to complete the sealing. When disassembling, press the pressing part upwards, the claws open outwards, and then the pipe is released and pulled out.

[0014] This solution allows for quick disassembly and assembly without the need for other fixing parts, thus saving on other components and reducing costs. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figs. 1-2In this embodiment of the present invention, a novel quick-connect fitting for a water purifier faucet includes a pipe body 1, with an externally threaded interface 2 at the upper end of the pipe body 1 and a connector 3 at the lower end of the pipe body 1. A snap-fit ​​ring 4 is inserted into the connector 3, and a pressing member 5 is slidably connected to the inner side of the snap-fit ​​ring 4. A sealing ring 6 is placed on the inner side of the upper end of the pressing member 5. The upper part of the pressing member 5 has several outwardly opening claws 9, and the upper end of the claws 9 has a triangular cross-section clamp. A snap-fit ​​strip 10 is fixed on the inner side of the clamp. The sealing ring 6 is placed above the snap-fit ​​strip 10. A recessed groove is provided in the middle of the outer side of the clamp to reduce material consumption. A plug groove is fixed on the inner side of the upper end of the connector 3. 7. A sealing ring 8 is fixed to the outer side of the insertion groove 7. A guide flange is fixed to the inner side of the insertion groove 7. The outer side of the guide flange is arc-shaped and used to guide the insertion of the pipe. The sealing ring 8 has an L-shaped cross-section and is snapped onto the inner stepped surface of the insertion pipe 3. Several protrusions 11 are fixed to the outer side of the snapping ring 4. The protrusions 11 have a triangular cross-section and are easy to snap onto the insertion pipe 3. The outer side of the pipe body 1 has a corrugated groove 12. The corrugated groove 12 improves the elasticity and torsional force of the pipe body 1 and facilitates installation. The upper end of the claw 9 is located outside the sealing ring 8. When the claw 9 moves downward, the inner side of the upper end of the claw 9 squeezes the sealing ring 8, increasing the sealing consumption.

[0020] The working principle of this utility model is as follows: During assembly, the snap ring 4 is snapped onto the insertion tube 3, with the lower end face of the snap ring 4 flush with the insertion tube 3. Then, the sealing ring 6 is placed into the insertion tube 3, and the pressing part 5 is inserted to complete the assembly.

[0021] In use, insert the pipe into the connector 3. The pipe opens the sealing ring 6 and then inserts the end into the connector groove 7. After it is fully inserted, pull the pipe out downwards. The pipe then moves the pressing part 5 downwards. The pressing part 5 moves the claw 9 downwards. The locking ring 4 squeezes the claw 9. The claw 9 retracts inwards, thus squeezing the sealing ring 6. The claw 9 squeezes the sealing ring 8, completing the seal and installation.

[0022] During disassembly, press the pressing part 5 upwards, the claw 9 opens outwards, thereby releasing the pipe and pulling it out.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
