Description

Technical Field

[0001] This utility model relates to the field of sealing joint technology, and in particular to a fluid connector and sealing joint. Background Technology

[0002] Fluid connectors and sealing joints are important components used for connection and sealing in pipeline systems. Fluid connectors are used to connect pipeline devices that transport high-pressure production fluids, ensuring that the pipelines can move relative to each other without affecting fluid transmission. Sealing joints are key parts that work in conjunction with fluid connectors, achieving a tight connection through threads, clamps, etc., thereby preventing fluid leakage.

[0003] However, in existing technologies, sealing joints typically employ threaded connections and clamps for connection. Threaded connections, due to the need for a seal, require strict control of the installation torque during installation to ensure the tightness and sealing of the threaded connection. Furthermore, each disassembly for maintenance leads to a decrease in sealing performance. Clamp-type connections, compared to threaded connections, have a more complex assembly process and are inconvenient for disassembly and maintenance. Therefore, both of these connection methods suffer from inconvenient installation and disassembly, presenting certain limitations. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing sealing joints usually use threaded connections and claws to achieve connection, both of which are inconvenient to install and disassemble. Therefore, a fluid connector and sealing joint is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fluid connector and sealing joint, comprising a tee pipe and three connecting seats, the three connecting seats being respectively connected and fixed to three joints of the tee pipe, a connecting pipe being inserted into the middle of each of the three connecting seats, a slot being provided on the outer side of the middle of each connecting seat, a rotating groove being provided on one side of the end of the slot, and arc-shaped limiting plates being fixedly installed at both ends of one side of the rotating groove, an insertion hole being provided at one end of each of the two arc-shaped limiting plates, a T-shaped insertion rod being fixedly installed at one end of the connecting pipe, an installation hole being provided in the middle of one side of the connecting seat, a positioning hole being provided in the middle of the upper end of the connecting pipe, the installation hole and the positioning hole being connected, a retaining pin being inserted between the installation hole and the positioning hole, a pressure plate being rotatably installed in the middle of the installation hole, a screw being threadedly connected to one side of the middle of the connecting seat, one end of the screw abutting against one end of the pressure plate, a retaining block being fixedly installed in the middle of the lower end of the retaining pin, and the other end of the pressure plate abutting against the retaining block.

[0006] Preferably, the larger diameter end of the T-shaped insert is slidably engaged between the two arc-shaped limiting plates and the insertion hole.

[0007] Preferably, the smaller end of the T-shaped plug is slidably engaged with the middle of the two arc-shaped limiting plates, and one end of the T-shaped plug abuts against the side away from the plug hole on the two arc-shaped limiting plates.

[0008] Preferably, the connecting tube is inserted into the middle of the slot.

[0009] Preferably, a slot is provided on the outer side of the mounting hole, and a protective cover is inserted into the middle of the slot.

[0010] Preferably, the tee pipe, the connector, and the connecting pipe are connected in a continuous manner.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, when installing the connecting pipe, align the T-shaped insert at the end of the connecting pipe with the insertion hole and insert it until it touches the bottom. Then rotate the connecting pipe to rotate the T-shaped insert to the side away from the insertion hole and abut it. At this time, the positioning hole is exactly below the mounting hole. Then insert the clip along the mounting hole and positioning hole. During the process, the clip on one side of the clip will drive the pressure plate to rotate. When the clip touches the bottom, the pressure plate will return to its original position. At this time, the operator will turn the screw to move its end down until it abuts against one end of the pressure plate, while the other end of the pressure plate rests on the top of the clip, thereby limiting the clip. At this time, the connection between the connecting pipe and the connecting seat can be completed. When disassembling and maintaining, turn the screw back to remove the limitation on the pressure plate, so that the operator can pull out the clip and remove the limitation on the rotation angle of the connecting pipe at the same time. The operator can then rotate the connecting pipe to rotate the T-shaped insert to the insertion hole to complete the disassembly. The installation and disassembly are simple and quick, and the sealing performance of the next connection will not be affected during disassembly and maintenance.

[0013] 2. In this utility model, by providing a removable protective cover on the outside of the mounting hole, the protective cover can prevent external dust and air from directly contacting the screw and causing it to rust. Rust will cause the threads to be unclear and difficult to disassemble, affecting subsequent maintenance, thus having higher practicality. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1-5 As shown, this utility model provides a fluid connector and sealing joint, including a tee pipe 1 and three connecting seats 11. The three connecting seats 11 are respectively connected and fixed to three joints of the tee pipe 1. A connecting pipe 2 is inserted into the middle of each of the three connecting seats 11. A slot 12 is opened on the outer side of the middle of each connecting seat 11. A rotating groove 13 is opened on one side of the end of the slot 12. Arc-shaped limiting plates 14 are fixedly installed at both ends of one side of the rotating groove 13. An insertion hole 15 is opened at one end of each of the two arc-shaped limiting plates 14. One end of the connecting pipe 2 is fixedly installed. There is a T-shaped insert 22, and a mounting hole 26 is opened in the middle of one side of the connecting seat 11. A positioning hole 21 is opened in the middle of the upper end of the connecting pipe 2. The mounting hole 26 and the positioning hole 21 are connected. A clip 25 is inserted between the mounting hole 26 and the positioning hole 21. A pressure plate 27 is rotatably installed in the middle of the mounting hole 26. A screw 28 is threadedly connected to one side of the middle of the connecting seat 11. One end of the screw 28 abuts against one end of the pressure plate 27. A clip 29 is fixedly installed in the middle of the lower end of the clip 25. The other end of the pressure plate 27 abuts against the clip 29.

[0023] The specific setup and function of this embodiment are described below. When installing the connecting pipe 2, the T-shaped insert 22 at the end of the connecting pipe 2 is aligned with the insertion hole 15 and inserted until it touches the bottom. Then, the connecting pipe 2 is rotated so that the T-shaped insert 22 rotates to the side away from the slot 13 of the insertion hole 15 and abuts against it. At this time, the positioning hole 21 is exactly below the mounting hole 26. Then, the retaining pin 25 is inserted along the mounting hole 26 and the positioning hole 21. During the process, the retaining block 29 on one side of the retaining pin 25 will drive the pressure plate 27 to rotate. When the retaining pin 25 touches the bottom, the pressure plate 27 will return to its original position. At this time, the operator turns the screw 28 to make the end of the retaining pin 25 rotate. The part moves down until it abuts against one end of the pressure plate 27, while the other end of the pressure plate 27 rests on top of the locking block 29, thereby limiting the locking pin 25. At this point, the connection between the connecting pipe 2 and the connecting seat 11 can be completed. When disassembling and maintaining, turn the screw 28 back to remove the limiting effect on the pressure plate 27, so that the operator can pull out the locking pin 25 and at the same time remove the limiting effect on the rotation angle of the connecting pipe 2. This allows the operator to rotate the connecting pipe 2 so that the T-shaped insert 22 can be rotated to the insertion hole 15 to complete the disassembly. The installation and disassembly are simple and quick, and the sealing performance of the next connection will not be affected during disassembly and maintenance.

[0024] Example 2, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the larger diameter end of the T-shaped plug 22 is slidably engaged between the two arc-shaped limiting plates 14 and the insertion hole 15, and the smaller diameter end of the T-shaped plug 22 is slidably engaged in the middle of the two arc-shaped limiting plates 14. One end of the T-shaped plug 22 abuts against the side away from the insertion hole 15 on the two arc-shaped limiting plates 14. The connecting pipe 2 is inserted into the middle of the slot 12. A slot 23 is provided on the outside of the mounting hole 26. A protective cover 24 is inserted into the middle of the slot 23. The three-way pipe 1, the connecting seat 11, and the connecting pipe 2 are connected.

[0025] The overall effect of this embodiment is as follows: When installing the connecting pipe 2, the T-shaped insert 22 at the end of the connecting pipe 2 is aligned with the insertion hole 15 and inserted until it touches the bottom. Then, the connecting pipe 2 is rotated so that the T-shaped insert 22 rotates to the side away from the slot 13 of the insertion hole 15 and abuts against it. At this time, the positioning hole 21 is exactly below the mounting hole 26. Then, the locking pin 25 is inserted along the mounting hole 26 and the positioning hole 21. During the process, the locking block 29 on one side of the locking pin 25 will drive the pressure plate 27 to rotate. When the locking pin 25 touches the bottom, the pressure plate 27 will return to its original position. At this time, the operator turns the screw 28 so that its end moves down until it abuts against one end of the pressure plate 27, while the other end of the pressure plate 27 rests on top of the locking block 29, thereby limiting the locking pin 25. The connection between the connecting pipe 2 and the connecting seat 11 can be completed. During disassembly and maintenance, the screw 28 is reversed to remove the restriction on the pressure plate 27, allowing the operator to pull out the clip 25 and simultaneously remove the restriction on the rotation angle of the connecting pipe 2. This allows the operator to rotate the connecting pipe 2 so that the T-shaped plug 22 is rotated to the plug hole 15 to complete the disassembly. The installation and disassembly are simple and quick, and the sealing performance of the next connection will not be affected during disassembly and maintenance. Furthermore, a removable protective cover 24 is provided on the outside of the mounting hole 26. The protective cover 24 can prevent external dust and air from directly contacting the screw 28 and causing it to rust. Rust will cause the threads to become unclear and difficult to disassemble, affecting subsequent maintenance, thus making it more practical.

[0026] The usage and working principle of this device are as follows: When installing the connecting pipe 2, align the T-shaped insert 22 at the end of the connecting pipe 2 with the insertion hole 15 and insert it until it touches the bottom. Then rotate the connecting pipe 2 so that the T-shaped insert 22 rotates to the side away from the slot 13 of the insertion hole 15 and abuts against it. At this time, the positioning hole 21 is exactly below the mounting hole 26. Then insert the locking pin 25 along the mounting hole 26 and the positioning hole 21. During the process, the locking block 29 on one side of the locking pin 25 will drive the pressure plate 27 to rotate. When the locking pin 25 touches the bottom, the pressure plate 27 will return to its original position. At this time, the operator will turn the screw 28 so that its end moves down until it abuts against one end of the pressure plate 27. The pressure plate 2... The other end of 7 rests on top of the locking block 29, thereby limiting the locking pin 25. At this time, the connection between the connecting pipe 2 and the connecting seat 11 can be completed. When disassembling and repairing, reverse the screw 28 to remove the limitation on the pressure plate 27, so that the operator can pull out the locking pin 25 and remove the limitation on the rotation angle of the connecting pipe 2. The operator can then rotate the connecting pipe 2 to rotate the T-shaped plug 22 to the plug hole 15 to complete the disassembly. A disassembly protective cover 24 is also provided on the outside of the mounting hole 26. The protective cover 24 can prevent external dust and air from directly contacting the screw 28 and causing it to rust, thus having higher practicality.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
