Description

Technical Field

[0001] The utility model relates to the technical field of plugs, in particular to a plug with a quick connection structure. Background Art

[0002] In modern industry and daily life, the demand for plugging the ports of various pipelines, containers and equipment is increasing day by day. The demand for plugs that can achieve quick connection is becoming more and more urgent. This demand not only requires simple and rapid connection operations, but also needs to ensure good sealing performance and stability to adapt to different working environments and pressure conditions.

[0003] Chinese Utility Model Patent Publication No.: CN 219673271 U3, discloses: a plug for a flow port. The plug for the flow port is composed of upper and lower bases, elastic blocks and sealing rings. Both types of materials are available, which can ensure the sealing performance during the processing. The adjustable plug between the rigid materials also facilitates the adjustment operation by workers. However, the plug for the flow port does not design multiple fastening methods, which easily leads to the use of a single tool for fastening during connection, resulting in a large overall limitation. Moreover, the plug for the flow port does not design multiple connection methods. When connecting pipes with different diameters, it is easy to replace the plug, resulting in poor overall diversity. Summary of the Invention

A plug cover 2 is fixedly installed at the top of the connecting column 1. A fixed block 3 is fixedly installed at the top of the plug cover 2. A first limiting groove 6 is opened on one side of the plug cover 2 close to the connecting column 1. A card block 7 is opened inside the top of the first limiting groove 6. A first sealing ring 8 is arranged inside the first limiting groove 6. A second groove 9 is opened at the top of one side of the first sealing ring 8. A second sealing ring 10 is fixedly installed on the outside of the first sealing ring 8. A second limiting groove 12 is opened on the outside of the connecting column 1. A connecting block 14 is fixedly installed at the bottom of the connecting column 1. A limiting block 16 is fixedly installed at the bottom of the plug cover 2. A second sealing gasket 17 is fixedly installed at the bottom of the limiting block 16.

[0030] Specifically, a card slot 4 is opened at the top of the fixed block 3. The cross-section of the fixed block 3 and the card slot 4 is in a "regular hexagon" structure. The diameter of the fixed block 3 is larger than the diameter of the card slot 4. A first groove 5 is opened inside the card slot 4. The cross-section of the first groove 5 is in a "cross" structure. The advantage is that through the regular hexagon fixed block 3 and the card slot 4, when installing the overall plug, a hexagon wrench with a larger diameter can be inserted outside the fixed block 3, and a hexagon wrench with a smaller diameter can also be inserted inside the card slot 4 to realize the rotation of the plug. At the same time, in cooperation with the first groove 5, a socket wrench can also be inserted into the first groove 5 to realize the rotation of the plug. The installation tool can be selected according to the actual situation, improving the convenience during connection.

[0031] Specifically, the length of the second sealing ring 10 extends to the outside of the connecting column 1. Both the first sealing ring 8 and the second sealing ring 10 are rubber sealing rings. The advantage is that through the cooperation of the first sealing ring 8 and the second sealing ring 10, when the plug is connected to the pipeline, one end of the pipeline can be attached to the first sealing ring 8 and the second sealing ring 10, avoiding internal leakage and affecting normal use.

[0032] Specifically, the first limiting groove 6 and the clamping block 7 are adapted to each other. There are the same number of the first limiting grooves 6 and the clamping blocks 7, and the multiple first limiting grooves 6 and the clamping blocks 7 are annularly distributed about the central line of the connecting column 1. The advantage is that through the cooperation of the first limiting groove 6 and the clamping block 7, when installing the first sealing ring 8, the first sealing ring 8 can be first snapped into the first limiting groove 6. Since the rubber material has strong deformation, when the first sealing ring 8 is snapped in, through the adaptation of the first limiting groove 6 and the clamping block 7, its quick alignment can be achieved, and it is prevented from easily falling off.

[0033] Embodiment 2: As Figures 2-6 shown, as an improvement over the previous embodiment.

[0034] Specifically, a first sealing gasket 13 is arranged inside the second limiting groove 12, and the diameter of the first sealing gasket 13 is larger than the diameter of the connecting column 1. The advantage is that through the cooperation of the second limiting groove 12 and the first sealing gasket 13, when connecting through the external thread 11, the first sealing gasket 13 can be made to fit against the inner wall of the pipeline, thereby improving the overall sealing performance and preventing it from easily leaking.

[0035] Specifically, an external thread 11 is arranged on the outer side of the connecting column 1, and an internal thread 15 is provided inside the connecting column 1. The lengths of the external thread 11 and the internal thread 15 are the same. The advantage is that through the cooperation of the external thread 11 and the internal thread 15, when installing a pipeline with a larger diameter, quick connection can be achieved through the external thread 11, and when connecting a pipeline with a smaller diameter, connection can be made through the internal thread 15, which can improve the diversity in the use of the overall plug and facilitate quick connection.

[0036] Specifically, the limiting block 16 and the second sealing gasket 17 are located inside the connecting column 1, and the second sealing gasket 17 is a rubber sealing gasket. The advantage is that through the design of the limiting block 16 and the second sealing gasket 17, when connecting through the internal thread 15, the second sealing gasket 17 can be made to fit against the pipeline, and at the same time, the plug cover 2 can also provide a certain degree of sealing performance. The cooperation between the two can prevent leakage from easily occurring when used inside.

[0037] Working principle: During use, through the regular hexagon fixing block 3 and the card slot 4, when installing the overall plug, a hexagon wrench with a larger diameter can be inserted outside the fixing block 3, and a hexagon wrench with a smaller diameter can also be inserted into the inside of the card slot 4 to achieve the rotation of the plug. At the same time, in cooperation with the first groove 5, a socket wrench can also be inserted into the first groove 5 to achieve the rotation of the plug. The installation tool can be selected according to the actual situation to improve the convenience during connection. Through the cooperation of the first sealing ring 8 and the second sealing ring 10, when the plug is connected to the pipeline, one end of the pipeline can be fitted with the first sealing ring 8 and the second sealing ring 10 to avoid internal leakage and affect normal use. Through the cooperation of the first limiting groove 6 and the clamping block 7, when installing the first sealing ring 8, the first sealing ring 8 can be first snapped into the first limiting groove 6. Due to the strong deformation of the rubber material, when the first sealing ring 8 is snapped in, it can be adapted through the first limiting groove 6 and the clamping block 7 to achieve its quick alignment and prevent it from easily falling off. Through the cooperation of the second limiting groove 12 and the first sealing gasket 13, when connecting through the external thread 11, the first sealing gasket 13 can be made to fit the inner wall of the pipeline, thereby improving the overall sealing performance and preventing it from easily leaking. Through the cooperation of the external thread 11 and the internal thread 15, when installing a pipeline with a larger diameter, quick connection can be achieved through the external thread 11, and when connecting a pipeline with a smaller diameter, connection can be achieved through the internal thread 15, which can improve the diversity of the overall plug during use and facilitate quick connection. Through the design of the limiting block 16 and the second sealing gasket 17, when connecting through the internal thread 15, the second sealing gasket 17 can be made to fit the pipeline, and at the same time, the plug cover 2 can also play a certain sealing role. The cooperation between the two can prevent leakage from easily occurring when used internally.
