Description

Technical Field

[0001] This utility model belongs to the field of quick-connect plug technology, specifically relating to a quick-connect plug with a sealing ring and a fixing pressure ring. Background Technology

[0002] In fluid or gas transmission systems, quick-connect plugs are widely used in automotive manufacturing, industrial equipment, aerospace, and many other fields due to their convenient and efficient connection. However, traditional quick-connect plug internal sealing ring installation methods often suffer from insecure fixation and unstable sealing performance. When the sealing ring is subjected to factors such as medium pressure fluctuations and temperature changes during long-term use, it is prone to displacement and deformation, leading to leaks at the connection point. This not only wastes resources but may also cause safety accidents.

[0003] Some quick-connectors use a simple embedding method to fix the sealing ring, lacking effective limiting and anti-loosening structures. Under frequent insertion and removal operations, the sealing ring is prone to loosening or even falling off, failing to guarantee the normal operation of the system. Furthermore, the existing quick-connectors are structurally designed to make it difficult to achieve a tight fit between the sealing ring and the inner wall of the connector, failing to meet the stringent sealing performance requirements under complex operating conditions such as high pressure and high flow rate. Therefore, designing a quick-connector with a reasonable structure, reliable sealing, and a securely fixed sealing ring has become an urgent technical challenge. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a quick connector with a sealing ring fixing pressure ring, wherein the quick connector has a sealing ring inside, an annular support platform inside the quick connector, a sealing ring fixing pressure ring is provided above the annular support platform, the sealing ring is located between the annular support platform and the sealing ring fixing pressure ring, the sealing ring fixing pressure ring is interference-fitted with the quick connector, the inner side of the sealing ring fixing pressure ring is provided with a plurality of evenly spaced inner positioning grooves, the outer side of the sealing ring fixing pressure ring is provided with a plurality of evenly spaced outer positioning grooves, and the inner wall of the quick connector is provided with a plurality of positioning blocks, the positioning blocks cooperating with the outer positioning grooves and respectively located in the corresponding outer positioning grooves.

[0005] As a preferred embodiment of the above technical solution, the inner wall of the quick plug is provided with an annular protrusion and an annular boss, the annular boss is located between the annular protrusion and the annular support platform, and the sealing ring fixing pressure ring is sandwiched between the annular protrusion and the annular boss.

[0006] As a preferred embodiment of the above technical solution, the two ends of the annular protrusion smoothly transition with the inner wall of the quick plug.

[0007] As a preferred embodiment of the above technical solution, the inner side of the sealing ring fixing pressure ring has a guide slope.

[0008] As a preferred embodiment of the above technical solution, the quick plug is equipped with a U-shaped retaining spring, and the two sides of the quick plug are respectively provided with side openings for the U-shaped retaining spring to extend into.

[0009] The beneficial effects of this utility model are as follows: By cooperating with the annular support platform and the sealing ring fixing ring, the sealing ring is securely clamped, effectively preventing displacement and deformation under pressure fluctuations and temperature changes, significantly improving sealing performance, preventing leakage, and reducing resource waste and safety risks. The design of the positioning block and outer positioning groove enhances the connection stability between the sealing ring fixing ring and the quick-connect plug. Combined with the limiting effect of the annular protrusion and annular boss, it is not easy to loosen or fall off even with frequent insertion and removal. The inner positioning groove on the inner side of the sealing ring fixing ring further optimizes the installation of the sealing ring, and the inner guide slope facilitates assembly. The U-shaped retaining spring provides additional reinforcement to the overall structure, enabling the quick-connect plug to operate stably under complex conditions such as high pressure and high flow rate, meeting diverse application needs.

[0015] like Figure 1-2 As shown, a quick-connect plug 1 with a sealing ring retaining pressure ring has a sealing ring 2 inside. An annular support platform 3 is located inside the quick-connect plug 1, and a sealing ring retaining pressure ring 4 is positioned above the annular support platform 3. The sealing ring 2 is located between the annular support platform 3 and the sealing ring retaining pressure ring 4. The sealing ring retaining pressure ring 4 is press-fitted with the quick-connect plug 1. The inner surface of the sealing ring retaining pressure ring 4 has several evenly spaced inner positioning grooves 5, and the outer surface of the sealing ring retaining pressure ring 4 has several evenly spaced outer positioning grooves 6. Several positioning blocks 7 are provided on the inner wall of the quick-connect plug 1, and the positioning blocks 7 cooperate with the outer positioning grooves 6 and are respectively located in their respective outer positioning grooves 6. The sealing ring 2 is fixed by the sealing ring retaining pressure ring 4, preventing it from misaligning or falling off inside the quick-connect plug 1, ensuring a sealing effect when the quick-connect plug 1 is connected to other plugs. The cooperation between the positioning blocks 7 and the outer positioning grooves 6 prevents relative rotation between the sealing ring retaining pressure ring 4 and the quick-connect plug 1. Several positioning parts are provided at the insertion points of other plugs into the quick-connect plug 1, and these positioning parts correspond to the inner positioning grooves 5. The inner positioning groove 5 cooperates with the positioning part of other plugs to prevent relative rotation between the sealing ring fixing pressure ring 4 and other plugs.

[0016] Furthermore, the inner wall of the quick connector 1 is provided with an annular protrusion 8 and an annular boss 9. The annular boss 9 is located between the annular protrusion 8 and the annular support platform 3, and the sealing ring fixing pressure ring 4 is sandwiched between the annular protrusion 8 and the annular boss 9. The annular protrusion 8 and the annular boss 9 respectively limit the upper and lower ends of the sealing ring fixing pressure ring 4 to prevent it from falling off.

[0017] Furthermore, both ends of the annular protrusion 8 smoothly transition into the inner wall of the quick-connect plug 1. This facilitates the locking ring 4 of the sealing ring to be engaged between the annular protrusion 8 and the annular boss 9.

[0018] Furthermore, the inner side of the sealing ring fixing ring 4 has a guide slope 10. The guide slope 10 facilitates the accurate and smooth insertion of other connectors into the quick plug 1 for docking.

[0019] Furthermore, a U-shaped retaining spring 11 is installed on the quick connector 1, and side openings 12 are provided on both sides of the quick connector 1 for the U-shaped retaining spring 11 to extend into. The U-shaped retaining spring 11 enables the quick connector 1 to maintain a fixed connection with other connectors and prevents the quick connector 1 from falling off.
