[0023] Example

[0024] refer to Figures 1 to 6This embodiment of a hydraulic hose quick-connect plug includes a hose body 1. A mating block 7 is snapped onto one side of the hose body 1. A first groove 2 is formed on one side of the hose body 1, and a second groove 3 is formed on the inner wall of the first groove 2. A circular groove 4 is formed on the inner side of the first groove 2. A first locking block 8 that matches the first groove 2 is fixedly connected to the other side of the mating block 7. A second locking block 9 that matches the second groove 3 is fixedly connected to the outer side of the first locking block 8. The second locking block 9 is snapped into the inner side of the circular groove 4. A sealing block 10 is threaded onto one side of the mating block 7. A plug body 11 is installed on one side of the sealing block 10. A switch is installed on the top of the plug body 11. The bottom end of the valve 12 and the plug body 11 is threaded with a connecting plate 14. The bottom end of the connecting plate 14 is provided with a discharge head 15. In use, the second locking block 9 is first sent into the circular groove 4, and then the second locking block 9 is adjusted to a position that is not corresponding to the second locking groove 3. This allows the second locking block 9 to be effectively locked in place, so as to prevent the connecting block 7 from falling off. At the same time, it will not hinder the normal use of the plug body 11. When the plug body 11 needs to be disassembled later, the second locking block 9 is first adjusted to a corresponding angle with the second locking groove 3, and then the first locking block 8 can be pulled out directly. This achieves the effect of convenient and quick disassembly and assembly of the plug body 11.

[0025] refer to Figures 1 to 3 A retaining spring 5 matching the second retaining block 9 is installed on the inner side of the circular groove 4. The other side of the second retaining block 9 is engaged with one side of the retaining spring 5. The second retaining block 9 is engaged with the inner side of the circular groove 4 through the retaining spring 5. A first sealing ring 6 is fixedly connected to one side of the oil pipe body 1. The first sealing ring 6 is 5 mm thick and made of rubber material. One side of the first sealing ring 6 is in contact with the other side of the docking block 7. Due to the presence of the retaining spring 5, the engagement of the retaining spring 5 can further limit the position of the second retaining block 9, thereby further improving the stability of the engagement of the second retaining block 9. When the second retaining block 9 is engaged, the docking block 7 will be pressed. After the second retaining block 9 is engaged, the rubber rebound of the first sealing ring 6 can also make the second retaining block 9 engage more tightly, and at the same time, it can also play a good sealing and protective role.

[0026] refer to Figure 3 and Figure 4 The bottom end of the plug body 11 is provided with a first threaded groove 13, and the top end of the connecting plate 14 is fixedly connected with a first connecting sleeve 16. The outer wall of the first connecting sleeve 16 is provided with a first external thread 17 that matches the first threaded groove 13. The first connecting sleeve 16 is threadedly connected to the inner side of the first threaded groove 13 through the first external thread 17. Due to the presence of the first connecting sleeve 16, the screwing in of the first connecting sleeve 16 can effectively limit the position of the connecting plate 14 to prevent the connecting plate 14 from shifting. It also facilitates the user to disassemble the connecting plate 14 later through the thread principle so as to clean or maintain the discharge head 15.

[0027] refer to Figure 5 and Figure 6 A second threaded groove 20 is provided on the other side of the sealing block 10. A second connecting sleeve 21 is fixedly connected to one side of the mating block 7. A second external thread 22 matching the second threaded groove 20 is provided on the outer wall of the second connecting sleeve 21. The second connecting sleeve 21 is threadedly connected to the inner side of the second threaded groove 20 through the second external thread 22. A second sealing ring 23 is fixedly connected to one side of the mating block 7. The thickness of the first sealing ring 6 is five millimeters. The second connecting sleeve 21 is located close to the inner side of the second sealing ring 23. One side of the second sealing ring 23 is in contact with the other side of the sealing block 10. The second sealing ring 23 is made of rubber material. A filter plate 18 is slidably connected to the inner wall of the sealing block 10. The filter plate 18 covers the inner side of the sealing block 10. A thread matching the second thread 20 is provided on the inner wall of the sealing block 10. The filter plate 18 is matched with the sliding groove 19. The filter plate 18 is slidably connected to the inner wall of the sealing block 10 through the sliding groove 19. Due to the presence of the second connecting sleeve 21, the second connecting sleeve 21 is screwed into the second threaded groove 20, which can effectively limit the position of the sealing block 10 to prevent the sealing block 10 from shifting. The second sealing ring 23 can effectively seal the connection point of the sealing block 10, which can play a good dustproof sealing role. The filter plate 18 can effectively filter the flowing oil and water, thereby improving the quality of oil and water discharge. When the filter plate 18 needs to be disassembled later, the second connecting sleeve 21 is first unscrewed by the thread principle, and then the filter plate 18 can be directly pulled out through the sliding groove 19, so as to facilitate the later cleaning or replacement of the filter plate 18.

[0028] Operating principle and advantages: In use, first insert the second locking block 9 into the circular groove 4, then adjust the second locking block 9 to a position that is not directly opposite to the second locking groove 3. This allows for effective locking of the second locking block 9, preventing the mating block 7 from falling off, and also ensuring the normal use of the plug body 11. When the plug body 11 needs to be disassembled later, first adjust the second locking block 9 to the corresponding angle with the second locking groove 3, and then directly pull out the first locking block 8. This facilitates quick and easy disassembly and assembly of the plug body 11. Due to the presence of the retaining spring 5, the locking action of the retaining spring 5 provides a secondary constraint on the position of the second locking block 9, further improving the stability of the locking action. When the second locking block 9 is engaged, the mating block 7 is pressed down. After the second locking block 9 is engaged, the rubber rebound of the first sealing ring 6 also makes the second locking block 9 engage more tightly, while also providing additional protection. Achieving good sealing and protection is achieved because the presence of the first connecting sleeve 16 effectively limits the position of the connecting plate 14 when it is screwed in, preventing displacement of the connecting plate 14. It also facilitates the user to disassemble the connecting plate 14 later through the thread principle for cleaning or maintenance of the discharge head 15. The presence of the second connecting sleeve 21, when screwed into the second threaded groove 20, effectively limits the position of the sealing block 10, preventing displacement of the sealing block 10. The second sealing ring 23 effectively seals the connection point of the sealing block 10, providing a good dustproof sealing effect. The filter plate 18 effectively filters the flowing oil and water, thereby improving the quality of the discharged oil and water. When the filter plate 18 needs to be disassembled later, the second connecting sleeve 21 is first unscrewed through the thread principle, and then the filter plate 18 is directly pulled out through the slide groove 19.
