[0023] 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.

[0024] like Figures 1 to 4 As shown, the present invention provides a quick-connect sealing structure for a plastic water outlet connection pipe, comprising:

[0025] Connecting fitting 1 includes pipe fitting 101, connectors 102 are fixedly connected to both sides of pipe fitting 101, anti-slip sleeves 103 are fixedly connected to the surface of pipe fitting 101, water outlet pipe 104 is provided on the outside of connector 102, and connecting ring 105 is fixedly connected to the surface of water outlet pipe 104.

[0026] Filter mechanism 2 is installed inside pipe fitting 101;

[0027] The reinforcement mechanism 3 includes a lifting sleeve 31. A lifting rod 32 is fixedly connected to the side of the lifting sleeve 31 near the pipe fitting 101. A lifting plate 33 is fixedly connected to the side of the lifting rod 32 near the connector 102, passing through the connector 102 and extending into the interior of the connector 102. A spring 34 is sleeved on the surface of the lifting rod 32. The side of the spring 34 near the lifting plate 33 is fixedly connected to the lifting plate 33, and the side of the spring 34 away from the lifting plate 33 is fixedly connected to the interior of the connector 102. A locking block 35 is fixedly connected to the outer end of the inner side of the lifting sleeve 31. The end of the locking block 35 away from the lifting sleeve 31 passes through the connecting ring 105 and extends into the interior of the connecting ring 105.

[0028] refer to Figure 2 The filter mechanism 2 includes a filter screen 21, a filter cotton 22 is provided on the right side of the filter screen 21, and a filter screen 23 is provided on the right side of the filter cotton 22. The surface of the filter cotton 22 is fixedly connected to the inside of the pipe fitting 101, the surface of the filter screen 23 is fixedly connected to the inside of the pipe fitting 101, and the surface of the filter screen 21 is fixedly connected to the inside of the pipe fitting 101.

[0029] As a technical optimization of this utility model, through the specific design of the filter mechanism 2, the filter screen 21 can intercept larger particulate impurities, the filter cotton 22 can adsorb fine impurities and some odors, and the filter screen 23 can further filter residual impurities. The multi-layer filtration significantly improves the liquid filtration effect, protects downstream pipelines and equipment, and extends the service life of the system.

[0030] refer to Figure 4 A sealing ring 4 is fixedly connected to the outside of the connector 102. The outer side of the sealing ring 4 passes through the connecting ring 105 and extends into the interior of the connecting ring 105.

[0031] As a technical optimization of this utility model, the sealing ring 4 on the outside of the connector 102 penetrates the inside of the connecting ring 105, forming an additional sealing barrier at the connection between the connector 102 and the connecting ring 105, which effectively enhances the sealing performance, reduces the possibility of liquid leakage, and ensures the sealing and safety of liquid transportation, especially suitable for high-pressure scenarios.

[0032] refer to Figure 2 The inner side of the surface of the water outlet pipe 104 is provided with a mating groove 5. The interior of the mating groove 5 is slidably connected with the soft pad buckle ring 6. The surface of the soft pad buckle ring 6 is fixedly connected to both sides of the inner wall of the pipe fitting 101.

[0033] As a technical optimization of this utility model, the water outlet pipe 104 is slidably connected to the inner groove 5 and the soft pad buckle ring 6. The sliding connection facilitates the quick docking of the water outlet pipe 104 and the pipe fitting 101, improving assembly efficiency. The soft pad material of the soft pad buckle ring 6 can adapt to a certain thermal expansion and contraction, enhancing the sealing and shock resistance of the connection part and reducing the risk of leakage caused by vibration or temperature changes.

[0034] refer to Figure 2 Both sides of the inner wall of the pipe fitting 101 are fixedly connected with limit sealing rings 7, and the outer side of the limit sealing rings 7 is in contact with the inner side of the outlet pipe 104.

[0035] As a technical optimization of this utility model, by setting a limiting sealing ring 7, the sealing characteristics can be used to further enhance the sealing performance between the pipe fitting 101 and the water outlet pipe 104 while limiting the position, reducing the risk of liquid leakage at the connection between the two, making the sealing effect better, and ensuring the safety and reliability of liquid transportation.

[0036] refer to Figure 4 Both sides of the lifting plate 33 are fixedly connected to sliders 8, and both sides of the inner wall of the connector 102 are provided with grooves 9, which are slidably connected to the sliders 8.

[0037] As a technical optimization of this utility model, the sliders 8 on both sides of the lifting plate 33 are slidably connected to the grooves 9 on the inner wall of the connector 102. The cooperation between the sliders 8 and the grooves 9 provides guidance for the lifting movement of the lifting plate 33, ensuring that it moves smoothly in a fixed direction, avoiding the lifting rod 32 from deviating or getting stuck, ensuring the accurate positioning of the locking block 35 in the reinforcement mechanism 3, and improving the working stability and reliability of the reinforcement mechanism 3.

[0038] The working principle and usage process of this utility model are as follows: During use, the user aligns the end of the water outlet pipe 104 with the connectors 102 on both sides of the pipe fitting 101 and inserts it into the pipe fitting 101. Because the locking block 35 has an inclined structure, the connecting ring 105 will push up the locking block 35 and the lifting sleeve 31 along the inclined surface of the locking block 35. The lifting sleeve 31 synchronously drives the lifting rod 32 and the lifting plate 33 to move. At this time, the sliders 8 on both sides of the lifting plate 33 slide in the grooves 9 on the inner wall of the connector 102 to ensure the smooth movement of the overall structure. Simultaneously, the spring 34 is compressed, causing the connecting ring 105 to fit tightly against the connector 102. Once the connecting ring 105 and the connector 102 are aligned... After completion, the spring 34 releases its elastic force to push the lifting plate 33, the lifting rod 32 and the lifting sleeve 31 back, allowing the locking block 35 on the lifting sleeve 31 to pass through the connecting ring 105 and extend into its interior for further reinforcement. During this process, the sealing ring 4 on the outside of the connector 102 passes through the interior of the connecting ring 105 to form a seal. During the liquid transportation process, the filter mechanism 2 inside the pipe fitting 101 begins to function. First, the filter screen 21 intercepts larger particulate impurities in the liquid. Then, the filter cotton 22 adsorbs small impurities and some odors in the liquid. Finally, the filter screen 23 further filters the residual impurities, thereby completing the filtration and transportation of the liquid.

[0039] In summary: This quick-connect sealing structure for the plastic water outlet connector, with its anti-slip sleeve 103 on the surface of the pipe fitting 101, facilitates gripping during installation and maintenance and prevents slippage; combined with the lifting sleeve 31, lifting rod 32, spring 34, and locking block 35 in the reinforcement mechanism 3, it achieves quick-connect connection while enhancing connection stability and improving assembly efficiency; the filter mechanism 2 can filter liquid impurities, making it adaptable to various scenarios and highly practical.
