Description

Technical Field

[0001] The utility model relates to the technical field of petroleum transportation, in particular to a pressure quick connector. Background Art

[0002] With the continuous development of modern industrial production, pipelines are used to transport gas, liquid and other resources. In the process of oil transportation, quick connectors are often used to quickly connect and disconnect pipelines and equipment. Quick connectors can not only quickly connect, but also disconnect oil pipelines or oil equipment of different sizes, pressures and media.

[0003] The Chinese utility model patent with announcement number CN208503736U discloses a pressure pipe quick connector, which includes a first connector, a second connector and a locking piece; the first connector and the second connector respectively include an annular body, and the outer side wall and the inner side wall of the body are respectively provided with a plurality of claws arranged along the circumferential direction of the body, and the claws extend outside the body port to form a clamping part, and when the first connector and the second connector are docked, the clamping parts are engaged with each other by rotation; the locking piece passes through the clamping part on the outer side of one of the connectors to the body of the other connector to limit the relative rotation of the first connector and the second connector, so that the first connector and the second connector are fixedly connected. The pressure pipe quick connector thus constructed is the same as the commonly used female pipe, and the two can be effectively connected in the factory. Moreover, the quick connector is not male or female, and both ends of the pipe that need to be connected on site are of the same model, which can greatly simplify the processing process and reduce the difficulty of installation; however, the pressure pipe quick connector only realizes the quick connection of the two through the alignment design, but is not convenient for quickly locking the connected pipes, making the two easy to fall off, and the pressure pipe quick connector is only designed with a single sealing gasket, which easily leads to poor sealing and leakage. Summary of the invention

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1:

[0029] This example provides a pressure quick connector solution, such as Figure 1 and Figure 2 As shown, the pressure quick connector specifically includes a connecting pipe 1, a plurality of positioning blocks 2 are fixedly installed on the outer side of the connecting pipe 1, a positioning bolt 3 is arranged on the outer side of the plurality of positioning blocks 2, a positioning sleeve 4 is arranged on the outer side of the connecting pipe 1, a sleeve 5 is fixedly installed on the top of the positioning sleeve 4, a positioning rod 6 is fixedly installed on the outer wall of the sleeve 5, a rotating column 7 is fixedly installed on the outer side of the positioning rod 6, a locking rod 8 is rotatably installed on the outer wall of the rotating column 7, a positioning hole 9 is opened on the outer side of the locking rod 8, a locking ring 10 is arranged inside the positioning hole 9, a first fixing hole 11 is opened on the outer side of the locking rod 8, a second fixing hole 12 is opened on the outer side of the positioning rod 6, a connecting seat 13 is fixedly installed on the top of the sleeve 5, a first sealing gasket 14 is arranged on the outer wall of the connecting seat 13, an external thread 15 is arranged on the outer side of the connecting seat 13, and a second sealing gasket 16 is arranged on the top of the connecting seat 13.

[0030] Specifically, Figure 3 and Figure 4As shown, the positioning block 2 and the positioning sleeve 4 in this example are plug-in installed, and the positioning bolt 3 passes through the positioning block 2 and extends to the inside of the positioning sleeve 4. In this way, through the design of the positioning block 2 and the positioning sleeve 4, when the pipe 1 and the positioning sleeve 4 are installed, the positioning block 2 can be inserted into the bottom of the positioning sleeve 4, which can play a fool-proof role and avoid easy misalignment during the installation process. In addition, with the positioning bolt 3, the positioning block 2 and the positioning sleeve 4 can be fixedly installed.

[0031] Specifically, Figure 5 As shown, the first fixing hole 11 and the second fixing hole 12 in this example are of the same size, the locking rod 8 is rotatably mounted with the positioning rod 6 through the rotating column 7, and the rotation angle of the locking rod 8 and the positioning rod 6 is 0° to 90°. In this way, through the design of the first fixing hole 11 and the second fixing hole 12, when the locking rod 8 is not in use, the locking rod 8 can overlap with the positioning rod 6, and then the fixing piece can be inserted into the first fixing hole 11 and the second fixing hole 12, so as to limit the locking rod 8 and the positioning rod 6, and can be quickly retracted when not in use.

[0032] Specifically, Figures 3 to 5 As shown, the positioning hole 9 and the locking ring 10 in this example are matched, and the locking ring 10 is a "circular" structure. With such a configuration, through the positioning hole 9 and the locking ring 10, after the pipe is connected, the locking rod 8 can be rotated, and then the locking ring 10 that moves in the positioning hole 9 can be connected to the joint at the other end, which can quickly lock the pipes to be connected and prevent the two from falling off easily.

[0033] Embodiment 2:

[0034] This example further provides an optimization solution based on the solution in the first embodiment.

In this way, through the design of the two positioning rods 6, the rotating column 7, the locking rod 8, the positioning hole 9 and the locking ring 10, the joint and the pipe 1 can be locked from both sides, thereby ensuring the overall stability and avoiding the single component from being easily subjected to uneven force, which affects normal use.

[0037] Furthermore, in this example, the first sealing gasket 14 and the second sealing gasket 16 are rubber sealing gaskets, and the sleeve 5 is an aluminum alloy sleeve. In this way, the rubber first sealing gasket 14 and the second sealing gasket 16 can improve the sealing performance during connection because the rubber material has strong sealing performance, and in combination with the aluminum alloy sleeve 5, the service life of the sleeve 5 can be increased, thereby improving practicality.

[0038] With respect to the pressure quick connector solution formed based on the above-mentioned example solution, the following further illustrates its reference process and corresponding technical features.

[0041] On this basis, through the positioning hole 9 and the locking ring 10, after the pipeline is connected, the locking rod 8 can be rotated, and then the locking ring 10 that moves in the positioning hole 9 can be connected to the joint at the other end, which can quickly lock the pipeline to be connected and prevent the two from falling off easily.

[0042] On this basis, through the design of two positioning rods 6, rotating column 7, locking rod 8, positioning hole 9 and locking ring 10, the joint and pipe 1 can be locked from both sides, so as to ensure the overall stability and avoid uneven force on a single component, which affects normal use.
