[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 , Figure 2As shown, a quick-connect structure includes: a male connector 10, the first end of which is used to connect to a first pipe; a female connector 20, the first end of which is fitted onto the second end of the male connector 10; the second end of the female connector 20 is used to connect to a second pipe; a sealing structure 30, which is tightly installed on the outer surface of the second end of the male connector 10 and tightly fitted to the inner surface of the first end of the female connector 20; and a fixing structure 40, which is snapped onto the outside of the male connector 10 and the female connector 20, and is used to limit the relative position of the male connector 10 and the female connector 20 in the axial direction so that the sealing structure 30 is always radially tightly fitted to the inner surface of the first end of the female connector 20 and the outer surface of the second end of the male connector 10, respectively.

[0026] Specifically, in actual production engineering, it is sometimes necessary to connect two pipelines to allow the medium to flow between them. These two pipelines are the first pipeline and the second pipeline in this application. The quick-connect structure in this application is used to connect the first pipeline and the second pipeline, thus enabling them to flow together. In the quick-connect structure, the first end of the male connector 10 connects to the first pipeline, the first end of the female connector 20 connects to the first end of the male connector 10, and the second end of the female connector 20 connects to the second pipeline, thereby connecting the first pipeline and the second pipeline through the quick-connect structure. The sealing structure 30 is tightly installed on the outer surface of the second end of the male connector 10 and tightly fitted to the inner surface of the first end of the female connector 20. When the male and female connectors are mated, the sealing structure 30 is pressed between them, forming a radial seal. The fixing structure 40 adopts a snap-fit ​​type, restricting the relative position of the male connector 10 and the female connector 20 in the axial direction, ensuring that the sealing structure 30 is always tightly fitted with the mating surfaces of the male connector 10 and the female connector 20, maintaining a good sealing effect even under vibration or pressure changes. The snap-fit ​​design allows for quick connection and fixation without the need for tools or tightening screws, making it simple and efficient to operate.

[0027] In summary, the sealing structure 30 employs a radial sealing design. When the male connector 10 and female connector 20 are mated, the sealing structure 30 is pressed between them, forming a reliable seal. The fixing structure 40 prevents relative axial movement between the male connector 10 and female connector 20, thereby ensuring that the sealing structure 30 always fits tightly, maintaining a good sealing effect even under vibration or pressure changes. The simple structure simplifies the assembly process, improves work efficiency, and reduces maintenance costs, making it particularly suitable for pipe connections requiring frequent disassembly and assembly.

[0028] In one possible implementation, the male connector 10 includes:

[0029] A first tubular structure 11 has a first pagoda-shaped connector on the outer surface of its first end, and the first tubular structure 11 is connected to the first pipe through the first pagoda-shaped connector; the outer surface of the second end of the first tubular structure 11 is in contact with the inner surface of the first end of the female connector 20.

[0030] The first protrusion 12 is annular and sleeved on the outer surface of the first tubular structure 11. The first protrusion 12 is located between the first end of the first tubular structure 11 and the second end of the first tubular structure 11.

[0031] When the male connector 10 is inserted into the female connector 20, the first end face of the first boss 12 abuts against the end face of the first end of the female connector 20.

[0032] Specifically, a first pagoda-shaped connector is formed on the exterior of the first end of the first tubular structure 11, and the outer surface of the second end of the first tubular structure 11 is fitted with the female connector 20. The first boss 12 is integrally formed with the first tubular structure 11. The first boss 12, located between the first and second ends of the first tubular structure 11, provides axial positioning. When the male connector 10 is inserted into the female connector 20, the first end face of the first boss 12 abuts against the end face of the female connector 20. The positioning function of the first boss 12 ensures effective compression and tight fit of the sealing structure 30.

[0033] In one possible implementation, the female connector 20 includes:

[0034] The second tubular structure 21 has a second pagoda connector on the outer surface of its second end, and the second tubular structure 21 is connected to the second pipe through the second pagoda connector; the inner surface of the first end of the second tubular structure 21 is in contact with the outer surface of the second end of the first tubular structure 11.

[0035] The second protrusion 22 is annular and is sleeved on the outer surface of the second end of the second tubular structure 21.

[0036] When the male connector 10 and the female connector 20 are inserted, the first end face of the second boss 22 abuts against the first end face of the first boss 12.

[0037] Specifically, the second pagoda-shaped connector on the outer surface of the second end of the second tubular structure 21 is used to connect with the second pipe, while the inner surface of the first end of the second tubular structure 21 is fitted with the outer surface of the second end of the first tubular structure 11. The second boss 22 is integrally formed with the second tubular structure 21. The second boss 22, as a positioning element, is fitted onto the outer surface of the second tubular structure 21 to provide axial positioning. When the male connector 10 and the female connector 20 are inserted, when the first end face of the second boss 22 abuts against the first end face of the first boss 12, it indicates that the insertion position of the male connector 10 and the female connector 20 can ensure the sealing of the sealing structure 30, simplifying the assembly process. Through the positioning function of the second boss 22, the effective compression and tight fit of the sealing structure 30 are ensured.

[0038] In one possible implementation, the outer surface of the first end of the second tubular structure 21 has an annular groove formed radially therein, and the sealing structure 30 includes:

[0039] Sealing ring 31, the sealing ring being tightly fitted into the annular groove;

[0040] When the male connector 10 and the female connector 20 are inserted, the sealing ring 31 is tightly fitted to the inner surface of the first end of the second tubular structure 21.

[0041] Specifically, in the second tubular structure 21, an annular groove radially formed on the outer surface of the first end of the second tubular structure 21 is used to tightly fit the sealing ring 31. During installation, the sealing ring 31 is first fitted into the annular groove, and then when the male connector 10 and the female connector 20 are inserted, the sealing ring 31 is pressed between the inner surface of the second tubular structure 21 and the outer surface of the male connector 10, forming a radial seal. The radial seal ensures the tightness of fluid transmission.

[0042] In one possible implementation, the fixing structure 40 includes:

[0043] The first edge 41 has a first arc-shaped surface in the middle, and the first arc-shaped surface has a first strip groove.

[0044] The second edge 42 has a second arc-shaped surface in the middle, and the second arc-shaped surface has a second groove.

[0045] Wherein, the second retaining edge 42 is symmetrical to the first retaining edge 41; the width of the first strip groove and the second strip groove is greater than the total axial length of the first boss 12 and the second boss 22;

[0046] The first end of the first retaining edge 41 is connected to the first end of the second retaining edge 42; the openings of the first arc-shaped surface and the second arc-shaped surface are opposite to each other; when the first arc-shaped surface and the second arc-shaped surface are snapped onto the outside of the first tubular structure 11 and the second tubular structure 21, the first boss 12 and the second boss 22 are restricted within the frame of the first strip groove and the second strip groove.

[0047] Specifically, such as Figure 3 As shown, the first retaining edge 41 and the second retaining edge 42 in the fixing structure 40 are symmetrical. The width of the strip groove on its arc surface is greater than the total length of the first boss 12 and the second boss 22, ensuring that the male connector 10 and the female connector 20 can be restrained in the proper position after insertion. The snap-fit ​​structure effectively prevents relative axial movement of the connector, ensures the continuous tight fit of the sealing ring, and improves the sealing performance and reliability of the connector, making it particularly suitable for occasions requiring frequent disassembly and assembly. The first retaining edge 41 and the second retaining edge 42 are integrally formed.

[0048] In one possible implementation, the second end of the first retaining edge 41 extends in the direction opposite to the opening of the first arc-shaped surface, and the second end of the second retaining edge extends in the direction opposite to the opening of the second arc-shaped surface.

[0049] Specifically, the second ends of the first retaining edge 41 and the second retaining edge 42 extend in opposite directions. When the connector needs to be disassembled, the reverse-extending retaining edge ends provide an operating space that is easy for the fingers to grip. The user can easily apply force by pinching the retaining edge ends to make the buckle structure open outward and separate from the male and female connectors, achieving quick separation. During installation, the reverse-extending retaining edge ends can guide the buckle to align with the arc-shaped surface of the outer wall of the male and female connectors. By pressing the retaining edge ends, the strip groove can smoothly slide past the first boss 12 and the second boss 22 until the first boss 12 and the second boss 22 reach the limit position of the first strip groove and the second strip groove, reducing the assembly difficulty.

[0050] In one possible implementation, the sealing ring 31 is made of highly elastic rubber or silicone material.

[0051] Specifically, the sealing ring 31 is made of highly elastic rubber or silicone material. Firstly, its high elasticity allows the sealing ring 31 to deform sufficiently when the male connector 10 and female connector 20 are inserted, tightly filling the tiny gap between the annular groove and the inner surface of the second tubular structure 21, forming a reliable radial seal. Secondly, both rubber and silicone materials have excellent resistance to various media, allowing them to withstand long-term contact with multiple fluid media without swelling or corrosion. Thirdly, rubber or silicone materials possess good aging resistance, maintaining a stable elastic modulus during long-term use, ensuring durable and reliable sealing performance. Finally, their low-temperature toughness and high-temperature stability allow the sealing ring to maintain good sealing performance over a wide temperature range, making it particularly suitable for industrial environments with large temperature differences. These characteristics collectively ensure the long-term stable operation of the sealing joint under complex working conditions.

[0052] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
