Technical Field

[0001] The utility model relates to the technical field of quick joints, in particular to a quick joint connection structure with a self-sealing function. Background Art

[0002] A quick connector is a connector that can connect or disconnect pipes without tools. Due to the development of modern automation industry, it is required to quickly connect the fluid working medium in the working state and quickly disconnect in the non-working state, which has led to the rapid development of various quick connectors.

[0003] At present, the common quick connectors on the market are mainly ferrule threaded type, which usually adopts threaded connection, which is cumbersome to install and disassemble. Each installation and disassembly requires a lot of work for the staff. At the same time, the internal sealing is often only achieved by the sealing ring, and the overall sealing effect is relatively general. Therefore, in view of the above problems, we need to consider designing a self-sealing quick connector connection structure. Utility Model Content

[0007] In order to better achieve the above purpose, the utility model adopts a further technical solution: a sealing ring is arranged on the rear side of the first pipe, and the inner circle radius of the annular installation groove is equal to the outer circle radius of the second connecting ring.

[0008] In order to better achieve the above purpose, the utility model adopts a further technical solution: the rubber ring cooperates with the annular limiting groove, and the two limiting through grooves cooperate with the corresponding limiting blocks.

[0009] The advantages of the utility model are: a limiting mechanism is provided, and the limiting block is driven to move by pressing the bar button, so that the limiting block passes through and limits the corresponding limiting through groove, thereby effectively ensuring a stable connection between the first pipe and the second pipe, and the overall installation and disassembly are convenient and quick; the sealing ring is provided to improve the self-sealing property between the first pipe and the second pipe, and the rubber ring and the annular limiting groove can be used to further improve the overall self-sealing property while completing the preliminary limiting of the first pipe and the second pipe.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] Reference Figure 1-Figure 4As shown, a self-sealing quick connector connection structure comprises a first pipe 1 and a second pipe 2, a first connecting ring 3 is fixedly connected to the outer ring of the first pipe 1, a ring-shaped mounting groove 4 is provided on the rear side of the first connecting ring 3, a rubber ring 5 is fixedly connected in the ring-shaped mounting groove 4, two first connecting blocks 6 are fixedly connected to the rear side of the first pipe 1, and limiting through grooves 7 are provided on the right sides of the two first connecting blocks 6, a sealing ring 17 is provided on the rear side of the first pipe 1, and the sealing ring 17 can improve the self-sealing property between the first pipe 1 and the second pipe 2, a second connecting ring 8 is fixedly connected to the outer ring of the second pipe 2, the inner ring radius of the ring-shaped mounting groove 4 is equal to the outer ring radius of the second connecting ring 8, an annular limiting groove 9 is provided on the outer side of the second connecting ring 8, and the rubber ring 5 cooperates with the annular limiting groove 9 to preliminarily limit the first pipe 1 and the second pipe 2, and further improve the self-sealing property of the whole device; it also comprises two limiting mechanisms, and the two limiting mechanisms are used to limit the corresponding first connecting blocks 6 to the corresponding first connecting blocks 6. A connecting block 6 is fixedly connected, and the limiting mechanism includes a second connecting block 10 fixedly connected to the outer ring of the second pipe 2. A rectangular through groove 11 is opened on the front side of the second connecting block 10, and a limiting plate 12 that can move left and right is arranged in the rectangular through groove 11; the opposite sides of the two limiting plates 12 are elastically connected to the side of the corresponding rectangular through groove 11 close to the center of the second pipe 2 through two springs 13, and the two springs 13 can ensure the stable limiting of the corresponding limiting through groove 7 by the subsequent limiting blocks 14, and the opposite sides of the two limiting plates 12 are fixedly connected to the limiting blocks 14, and the two limiting through grooves 7 are matched with the corresponding limiting blocks 14. By passing the two limiting blocks 14 through the corresponding limiting through grooves 7 respectively, a stable connection between the first pipe 1 and the second pipe 2 is achieved, and the opposite sides of the two limiting plates 12 are fixedly connected to two connecting rods 15, and the other ends of each two matching connecting rods 15 pass through the corresponding rectangular through groove 11 and are fixedly connected with a strip button 16.

[0017] When in use, the staff first uses the thumb and index finger to press the two strip buttons 16 at the same time, and drives the two limit plates 12 to move toward each other through the four connecting rods 15, and drives the two limit blocks 14 to move toward each other to the leftmost end. At this time, the four springs 13 are all in a stressed and compressed state, and then the second connecting ring 8 is aligned with the annular mounting groove 4 and inserted. During the insertion process, it is necessary to ensure that the two first connecting blocks 6 are respectively aligned with the corresponding rectangular through grooves 11. When the rubber ring 5 is completely inserted into the annular limit groove 9, the insertion is stopped. At this time, the two first connecting blocks 6 will pass through the corresponding rectangular through grooves 11 , release the two strip buttons 16, and due to the reaction force of the four springs 13, the two limit plates 12 move back to each other, driving the two limit blocks 14 to penetrate the corresponding limit through grooves 7 respectively, so that the two limit blocks 14 can limit the two first connecting blocks 6, ensuring a stable connection between the first pipe 1 and the second pipe 2. When disassembly is required later, the two limit blocks 14 can be cancelled by pressing the two strip buttons 16 at the same time. The entire installation and disassembly process is convenient and quick. At the same time, the sealing ring 17 cooperates with the rubber ring 5 to effectively improve the self-sealing property of the entire device.
