[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A welded nylon hose adapter four-way structure includes a connecting pipe 1, a connecting mechanism 2 connected to the surface of the connecting pipe 1, and a sealing mechanism 3 fixedly connected to the side of the connecting mechanism 2 away from the connecting pipe 1.

[0027] The connecting mechanism 2 includes four connecting pipes 21, a fixed ring 22, a rotating rod 23, an upper rotating ring 24, a lower rotating ring 25, and three fixed rods 26. The connecting pipes 21 are fixedly connected to the surface of the connecting pipe 1. The fixed ring 22 is welded to the surface of the connecting pipe 21. The rotating rod 23 is rotatably connected to the surface of the fixed ring 22. The upper rotating ring 24 is fixedly connected to the side of the rotating rod 23 away from the fixed ring 22. The lower rotating ring 25 is welded to the bottom surface of the connecting pipe 21. The fixed rods 26 are welded to the bottom of the surface of the fixed ring 22. The side of the fixed rod 26 away from the fixed ring 22 is welded to the surface of the lower rotating ring 25.

[0028] In this embodiment: By setting the connecting pipe 1 as the main support structure, it provides the initial connection point with the external pipeline, ensuring the basic passage for fluid transmission. The connecting pipe 21 forms a four-way branch structure, realizing the simultaneous connection of pipelines in multiple directions, improving the flexibility of pipeline layout. The fixing ring 22 provides stable support for the rotating rod 23. It is firmly combined with the connecting pipe 21 by welding, enhancing the overall strength of the structure and ensuring that it will not loosen during long-term use. The rotating rod 23 realizes the opening and closing function of the upper half rotating ring 24, allowing nylon tubes or rubber hoses to be quickly inserted or removed, simplifying the installation process and improving operating efficiency. The upper half rotating ring 24 and the lower half rotating ring 25 cooperate to form a ring clamping structure. After being locked by the fixing screw 7, uniform pressure is applied to the pipeline to prevent the pipeline from falling off. It is suitable for vibration or high-pressure scenarios. When the upper half rotating ring 24 rotates, it can drive the upper sealing ring 33 to rotate synchronously through the limiting rod 32. The fixing rod 26 can strengthen the connection between the lower half rotating ring 25 and the connecting pipe 21, distribute the force, avoid stress concentration leading to weld breakage, and extend the service life.

[0029] Specifically, such as Figure 3 , Figure 4 As shown, the sealing mechanism 3 includes a sealing ring 31, six limiting rods 32, an upper sealing ring 33, a lower sealing ring 34, an injection groove 35, and an injection hole 36. The sealing ring 31 is located on the side of the connecting pipe 21 away from the connecting pipe 1.

[0030] Specifically, such as Figure 3 , Figure 4 As shown, the limiting rod 32 is welded to the surface of the upper half rotating ring 24 and the surface of the lower half rotating ring 25 respectively, and the upper sealing ring 33 is welded to the side of the limiting rod 32 away from the upper half rotating ring 24.

[0031] Specifically, such as Figure 3 , Figure 4 As shown, the lower sealing ring 34 is welded to the side of the limiting rod 32 away from the lower half rotating ring 25. The injection grooves 35 are respectively opened on the inner wall of the upper sealing ring 33 and the inner wall of the lower sealing ring 34. The injection hole 36 is opened on the top of the upper sealing ring 33.

[0032] In this embodiment: the sealing ring 31 provides an initial sealing barrier, filling the gap between the pipeline and the connecting pipe 21 interface, preventing fluid leakage under low pressure or static conditions. The three limiting rods 32 welded to the surface of the lower half rotating ring 25 can fix the position of the lower sealing ring 34, while the three limiting rods 32 welded to the surface of the upper half rotating ring 24 can fix the position of the upper sealing ring 33, so that the upper sealing ring 33 and the upper half rotating ring 24 move synchronously. The upper sealing ring 33 and the lower sealing ring 34 form an annular sealing cavity, which, together with the injection groove 35, stores sealant to achieve secondary sealing. In response to high pressure, high temperature or corrosive media, the injection groove 35 can limit the sealant and fix it to the external pipeline for secondary sealing. The injection hole 36 allows the user to easily inject sealant into the inside of the injection groove 35.

[0033] Specifically, such as Figure 5 As shown, a stopper cap 4 is snapped into the inner side of the injection hole 36, and the surface of the stopper cap 4 is engraved with anti-slip texture.

[0034] Specifically, such as Figure 5 As shown, reinforcing rings 5 ​​are welded to both sides of the limiting rod 32, and the surface of the reinforcing rings 5 ​​is coated with anti-corrosion paint.

[0035] In this embodiment: by setting a plug cap 4, the injection hole 36 is sealed by a snap-fit ​​method to prevent impurities from entering the sealant or the sealant from overflowing. By setting anti-slip texture, it is easy to quickly disassemble and assemble by hand without the need for tools, which improves maintenance efficiency and convenience. By setting a reinforcing ring 5, the structural strength of the connection between the limiting rod 32 and the upper sealing ring 33 and the lower sealing ring 34 is enhanced, the stress is distributed, and stress concentration is prevented from causing breakage. By setting an anti-corrosion coating, it can isolate media such as acids, alkalis and water vapor, and extend the service life of the structure in harsh environments.

[0036] Specifically, such as Figure 4 As shown, both sides of the upper rotating ring 24 and the lower rotating ring 25 are provided with connecting screw holes 6, and the inner side of the connecting screw holes 6 is threaded with a fixing screw 7.

[0037] Specifically, such as Figure 5 As shown, a handle 8 is welded to the top surface of the upper rotating ring 24, and the surface of the handle 8 is engraved with anti-slip texture.

[0038] In this embodiment: by setting the connecting screw hole 6, an installation base is provided for the fixing screw 7, realizing the rapid opening and closing and fastening of the ring structure. By setting the fixing screw 7, the upper and lower half rotating rings 25 are locked by the threaded connection, and uniform pressure is applied to the inserted nylon tube or rubber tube to form a firm clamping fixation. By setting the handle 8, it is convenient for the operator to quickly rotate the upper half rotating ring 24 to open and close. By setting the anti-slip texture, the friction is increased to prevent the hand from slipping.

[0039] Working principle: First, the operator opens the upper rotating ring 24 using the handle 8. When the upper rotating ring 24 is open, the upper sealing ring 33 is simultaneously opened by the limit rod 32. At this time, the operator inserts the nylon tube or rubber tube into the connecting pipe 21. After the nylon tube or rubber tube is inserted into the connecting pipe 21, the operator closes the upper rotating ring 24, so that the upper rotating ring 24 and the lower rotating ring 25 form a ring-shaped wrapping structure. The fixing screw 7 is tightened through the connecting screw hole 6 to apply uniform pressure to the pipeline. Then, when the upper rotating ring 24 and the lower rotating ring 25 are closed, the upper rotating ring 24 and the lower rotating ring 25 are closed. After the semi-rotating ring 25 is closed, the upper sealing ring 33 will also close with the lower sealing ring 34. Then, the operator injects sealant into the injection tank 35 through the injection hole 36. After the sealant is injected, the operator snaps the plug 4 into the injection hole 36. The sealant cures in the injection tank 35 to form a secondary sealing layer. Finally, the operator connects the four external pipes to the connecting pipe 21 in sequence. After that, when maintenance or replacement of the pipes is required, the operator unscrews the fixing screw 7 and rotates the handle 8 to open the upper semi-rotating ring 24, so that the pipes can be quickly disassembled.

[0040] 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.
