Description

Technical Field

[0001] This application relates to the field of electrical connection components technology, and more specifically, to a fluid connector. Background Technology

[0002] Fluid connectors are primarily used to connect or disconnect pipelines for the transmission of liquids, gases, and other fluid media. They ensure the safe, efficient, and sealed transmission of fluids between different pipes or equipment. However, during use, fluid connectors require frequent mating to control the connection or disconnection of the pipeline. In practice, it has been found that after a certain period of use, the sealing ring wears down on the relative moving surfaces of the sealing ring and the metal seat due to the frequent reciprocating motion of the sealing ring within the metal seat. This makes it difficult to guarantee the sealing performance, often resulting in fluid leakage from the pipeline.

[0003] In conclusion, ensuring the sealing performance of fluid connectors during long-term use is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a fluid connector whose sealing performance is guaranteed during long-term use.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A fluid connector, comprising:

[0007] A fixing component includes a base and a guide member. The base has a conveying channel. The guide member is inserted into the conveying channel, and its second end is supported on the inner wall of the base. The second end of the guide member has a guide port. A portion of the conveying channel located on one side of the second end of the guide member is a first sub-channel, and a portion of the conveying channel located on the other side of the second end of the guide member is a second sub-channel. The first sub-channel is connected to the second sub-channel through the guide port.

[0008] The movable component includes a sealing ring and a first reset member. The sealing ring is sleeved outside the first end structure of the guide member and is slidably disposed in the conveying channel to close or open the space between the first end of the guide member and the seat. The first reset member is connected to the fixing component and the sealing ring and is used to push the sealing ring to reset.

[0015] The second reset member is connected to the fixing component and the positioning sleeve, and is used to push the positioning sleeve to reset;

[0016] The inner wall of the positioning sleeve or the outer wall of the seat has a positioning groove, and the positioning ring is sleeved in the positioning groove to position the positioning sleeve.

[0017] Preferably, the inner wall of the second end of the seat has a first threaded structure to thread-connect the pipe opening structure.

[0018] Preferably, the seat body includes a connecting housing, a socket housing, and a first sealing ring;

[0019] The inner wall of the first end of the connecting housing has a second thread structure, and the outer wall of the second end of the socket housing has a third thread structure. The first end of the connecting housing is threadedly connected to the second end of the socket housing through the second thread structure and the third thread structure.

[0020] The inner wall of the second end of the connecting housing has the first threaded structure;

[0021] The first end of the socket housing has the positioning through hole;

[0022] The wear-resistant sleeve is fitted inside the socket housing;

[0023] The inner wall of the connecting housing or the outer wall of the socket housing has a first sealing groove, and the first sealing ring is fitted in the first sealing groove.

[0024] Preferably, it also includes a second sealing ring and a third sealing ring;

[0025] The inner wall of the socket housing has a second sealing groove, and the second sealing ring is fitted in the second sealing groove;

[0026] The first end of the guide member has a third sealing groove on its outer periphery, and the third sealing ring is fitted in the third sealing groove.

[0027] Preferably, the sealing ring has a first cylindrical section and a second cylindrical section, wherein the cross-sectional dimension of the first cylindrical section is larger than the cross-sectional dimension of the second cylindrical section;

[0028] The inner wall of the socket housing has an annular protrusion, the second sealing groove is provided on the annular protrusion, and the second cylindrical section can be inserted into or removed from the inner cavity of the annular protrusion;

[0029] The first cylindrical section is slidably fitted onto the wear-resistant sleeve;

[0030] Furthermore, the stepped surface of the sealing ring located between the first cylindrical section and the second cylindrical section can abut against or separate from the positioning surface of the annular protrusion end.

[0031] Preferably, the connecting housing has a third cylindrical section and a fourth cylindrical section, the third cylindrical section has the first threaded structure, the fourth cylindrical section has the second threaded structure, and the inner diameter of the third cylindrical section is smaller than the inner diameter of the fourth cylindrical section;

[0032] The second end of the flow guide abuts against the stepped surface between the third and fourth cylindrical sections.

[0033] Preferably, both the first reset member and the second reset member are springs;

[0034] One end of the first reset member abuts against the flow guide, and the other end abuts against the sealing ring;

[0035] One end of the second reset member abuts against the socket housing, and the other end abuts against the positioning sleeve.

[0036] In this application, the fixing component has a conveying channel on the base; the guide member has a variable cross-section structure, and the second end of the guide member is supported on the peripheral wall of the conveying channel. There is a space between the peripheral surface of the middle structure of the guide member and the peripheral wall of the conveying channel. Correspondingly, the guide member is inserted in the middle position along the length direction of the conveying channel, and a through hole extending along the extension direction of the conveying channel is opened on the second end of the guide member as a guide port, so that the first sub-channel of the conveying channel located on the side of the conveying channel located on the guide member and the part of the channel located between the middle structure of the guide member and the base are connected through the guide port.

[0037] In the active component, the sealing ring is a hollow cylindrical structure and is fitted around the outer periphery of the first end of the guide member. Correspondingly, the sealing ring is slidably inserted into the conveying channel along its extension direction. The conveying channel is a variable cross-section channel, allowing the sealing ring to seal against the peripheral wall of the small-diameter channel and the first end of the guide member. This prevents fluid from flowing through the gaps between the guide member and the sealing ring, and between the seat and the sealing ring. Therefore, when the fluid flows along the conveying channel, it first flows through a portion of the inlet channel in the seat, and then is blocked by both the guide member and the sealing ring. The fluid cannot continue to flow to the left; conversely, when the sealing ring slides into the large-diameter channel of the conveying channel, there is a space between the circumferential surface of the sealing ring and the circumferential wall of the conveying channel for fluid flow. When the fluid flows along the conveying channel, it first flows through a portion of the channel at the inlet end of the conveying channel in the seat, then flows through the channel between the first end of the guide and the inner wall of the seat, then flows through the channel between the sealing ring and the intermediate structure of the guide, and finally flows out of the fluid connector from a portion of the channel at the outlet end of the conveying channel in the seat after passing through the guide port. The fluid connector can then control the connection or disconnection of the pipeline.

[0038] Furthermore, a first reset component is provided on the fixing component. One end of the first reset component is connected to the sealing ring, and the other end is connected to the fixing component, so as to push the sealing ring to the right to reset, thereby sealing the space between the right end of the guide and the seat.

[0039] A wear-resistant sleeve is fitted onto one of the seat body and the sealing ring, and the wear-resistant sleeve is located between the seat body and the sealing ring. This allows the sealing ring and the seat body to slide together through the wear-resistant sleeve, effectively avoiding wear such as scratches that may occur from direct contact between the sealing ring and the seat body. This ensures the sealing performance of the fluid connector during long-term use and prevents metal debris generated by wear from damaging other components as the medium flows.

Detailed Implementation

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] The core of this application is to provide a fluid connector whose sealing performance is guaranteed during long-term use.

[0049] This application provides a fluid connector, including a fixed component 1, a movable component 2, and a wear-resistant sleeve 3. The fixed component 1 includes a base 11 and a guide member 12. The base 11 has a conveying channel; the guide member 12 is inserted into the conveying channel, and its second end is supported on the inner wall of the base 11. The second end of the guide member 12 has a guide port 121. A portion of the conveying channel on one side of the second end of the guide member 12 is a first branch channel, and a portion of the conveying channel on the other side of the second end of the guide member 12 is a second branch channel. The first branch channel is connected to the second branch channel through the guide port 121. The movable component 3... The moving component 2 includes a sealing ring 21 and a first reset member 22. The sealing ring 21 is sleeved on the outside of the first end structure of the guide member 12 and is slidably disposed in the conveying channel to close or open the space between the first end of the guide member 12 and the seat 11. The first reset member 22 is connected to the fixing component 1 and the sealing ring 21 and is used to push the sealing ring 21 to reset. The wear-resistant sleeve 3 is fixedly sleeved on one of the seat 11 and the sealing ring 21, and the sealing ring 21 is slidably fitted to the seat 11 through the wear-resistant sleeve 3.

[0050] Specifically, such as Figures 1 to 3As shown, in the fixing assembly 1, a conveying channel extending laterally is provided on the base 11; the guide member 12 has a variable cross-section structure. Specifically, the left end of the guide member 12 is supported on the peripheral wall of the conveying channel. There is a space between the peripheral surface of the middle structure of the guide member 12 and the peripheral wall of the conveying channel. Correspondingly, the guide member 12 is inserted laterally in the middle position of the conveying channel, and a through hole extending laterally is provided on the left end of the guide member 12 as a guide port 121, so that the first sub-channel of the conveying channel located on the left side of the guide member 12 and the part of the channel located between the middle structure of the guide member 12 and the base 11 can be connected through the guide port 121.

[0051] In the active component 2, the sealing ring 21 is a hollow cylindrical structure and is fitted around the outer periphery of the right end of the guide member 12. Correspondingly, the conveying channel is a variable cross-section channel. The sealing ring 21 is slidably inserted into the conveying channel laterally, and the sealing ring 21 can seal against the peripheral wall of the small-diameter channel and the right end of the guide member 12. Therefore, fluid cannot flow through the gaps between the guide member 12 and the sealing ring 21, or between the seat 11 and the sealing ring 21. Figure 2 As shown, when the fluid flows from right to left, it first flows through a portion of the passage at the right end of the conveying channel in the seat 11, and then is blocked by the guide member 12 and the sealing ring 21, thus preventing it from continuing to flow to the left; conversely, when the sealing ring 21 slides laterally into the large-diameter passage of the conveying channel, there is a space between the circumferential surface of the sealing ring 21 and the circumferential wall of the conveying channel, as shown... Figure 3 As shown, for fluid flow, when the fluid flows from right to left, it first flows through a portion of the channel at the right end of the delivery channel in the seat 11, then flows through the channel between the right end of the guide member 12 and the inner wall of the seat 11, then flows through the channel between the sealing ring 21 and the intermediate structure of the guide member 12, and finally flows out of the fluid connector from a portion of the channel at the left end of the delivery channel in the seat 11 after flowing through the guide port 121. The fluid connector can control the connection or disconnection of the pipeline.

[0052] Furthermore, a first reset member 22 is provided on the fixing component 1. One end of the first reset member 22 is connected to the sealing ring 21, and the other end is connected to the fixing component 1, so as to push the sealing ring 21 to reset to the right, thereby closing the space between the right end of the guide member 12 and the seat 11.

[0053] It should be noted that the type of the first reset component 22 is not limited, as long as it can achieve the above function. For example, the first reset component 22 includes a first magnet and a second magnet with the same poles. The first magnet is fixed on the sealing ring 21, and the second magnet is fixed on the fixing component 1. The second magnet is located to the left of the first magnet. Then the mutual repulsion between the second magnet and the first magnet can push the sealing ring 21 to the right.

[0054] Optionally, in some other embodiments, the wear-resistant sleeve 3 is sleeved on the outside of the sealing ring 21 and is fixedly connected to the sealing ring 21 by means of bonding, interference fit, or snap-fit, so that the sealing ring 21 can move along the seat 11 through the wear-resistant sleeve 3; preferably, in some embodiments, such as Figure 2 and Figure 3 As shown, the wear-resistant sleeve 3 adopts a straight cylindrical structure and is fitted inside the seat 11. It is fixedly connected to the seat 11 by means of bonding or interference fit, so that the sealing ring 21 can move along the wear-resistant sleeve 3. This configuration makes the structure of the fluid connector simple and easy to assemble. In summary, the sealing ring 21 and the seat 11 slide together through the wear-resistant sleeve 3, which effectively avoids wear that may be caused by direct contact between the sealing ring 21 and the seat 11, so as to ensure the sealing performance of the fluid connector during long-term use.

[0055] It should be noted that there are no restrictions on the type of wear-resistant sleeve 3, as long as it can achieve the above functions. For example, the wear-resistant sleeve 3 can be made of nylon, carbon fiber, or plastic.

[0056] To ensure the smooth movement of the sealing ring 21, based on the above embodiment, the wear-resistant sleeve 3 is interference-fitted to the seat 11 and / or bonded to the seat 11.

[0057] Based on the above embodiment, it also includes a second reset member 4, a positioning sleeve 5, a positioning ring 6, and a plurality of positioning beads 7; the first end sidewall of the seat 11 has a plurality of positioning through holes 1121, and a plurality of positioning beads 7 are rotatably disposed in the corresponding positioning through holes 1121 for abutting against and positioning a plug inserted into the first end of the seat 11; the positioning sleeve 5 is slidably sleeved on the outside of the first end of the seat 11 to loosen or press the positioning beads 7; the second reset member 4 is connected to the fixing component 1 and the positioning sleeve 5 for pushing the positioning sleeve 5 to reset; the inner wall of the positioning sleeve 5 or the outer wall of the seat 11 has a positioning groove, and the positioning ring 6 is sleeved in the positioning groove to position the positioning sleeve 5.

[0058] Specifically, such as Figures 1 to 3As shown, two or three equal numbers of positioning through holes 1121 are formed on the peripheral wall of the right end of the base 11. All positioning through holes 1121 are circular holes. Correspondingly, the fluid connector is equipped with a number of round beads 7 equal to the number of positioning through holes 1121. Several positioning beads 7 are rotatably embedded in their respective positioning through holes 1121. Correspondingly, a positioning sleeve 5 is fitted onto the outside of the right end of the base 11, and the positioning sleeve 5 can slide laterally with the base 11. A second reset member 4 is provided, with one end connected to a positioning sleeve 5 and the other end connected to a fixing component 1. It is used to push the positioning sleeve 5 to reset to the right to press the positioning bead 7. A positioning ring 6 is also provided, with an annular groove as a positioning groove on the outer circumferential surface of the right end of the seat 11. The positioning ring 6 is fitted in the positioning groove, and the outer circumferential structure of the positioning ring 6 protrudes from the positioning groove. The positioning ring 6 can be a snap ring or a shaft retaining ring, etc., so that the positioning sleeve 5 can be blocked by the positioning ring 6 and cannot be separated from the seat 11.

[0059] Furthermore, in some specific embodiments, after the positioning sleeve 5 moves to the left to the first extreme position, all the positioning beads 7 are exposed and can rotate freely without restriction; conversely, after the positioning sleeve 5 moves to the right to the second extreme position, all the positioning beads 7 are covered by the positioning sleeve 5 and abut against it to restrict the rotation of the positioning beads 7.

[0060] In use, first push the positioning sleeve 5 to move it to the left to the first extreme position, then insert the plug into the conveying channel from right to left. After the plug is inserted into place, release the positioning sleeve 5. Under the push of the second reset member 4, the positioning sleeve 5 will move to the right to the second extreme position to achieve the positioning of the plug.

[0061] Based on the above embodiment, the inner wall of the second end of the seat 11 has a first threaded structure to connect the pipe opening structure by thread.

[0062] Specifically, such as Figure 2 and Figure 3 As shown, a first thread structure is machined on the inner wall of the left end of the seat 11, that is, the left end of the seat 11 has an internal thread. With this configuration, the fluid connector can be securely and tightly connected to the pipe structure.

[0063] Based on the above embodiments, the base 11 includes a connecting housing 111, a socket housing 112, and a first sealing ring 113; the inner wall of the first end of the connecting housing 111 has a second thread structure, and the outer wall of the second end of the socket housing 112 has a third thread structure. The first end of the connecting housing 111 is threadedly connected to the second end of the socket housing 112 through the second thread structure and the third thread structure; the inner wall of the second end of the connecting housing 111 has a first thread structure; the first end of the socket housing 112 has a positioning through hole 1121; the wear-resistant sleeve 3 is sleeved inside the socket housing 112; the inner wall of the connecting housing 111 or the outer wall of the socket housing 112 has a first sealing groove, and the first sealing ring 113 is sleeved in the first sealing groove.

[0064] The base 11 consists of three parts: a connecting housing 111, a socket housing 112, and a first sealing ring 113, wherein, as shown in the figure... Figures 1 to 3 As shown, the right end of the connecting housing 111 on the left side is machined with a second thread structure, and the left end of the socket housing 112 on the right side is machined with a third thread structure. That is, the right end of the connecting housing 111 has an internal thread, and the left end of the socket housing 112 has an external thread. Thus, the left end of the socket housing 112 can be inserted into the right end of the connecting housing 111 to achieve a threaded connection. Correspondingly, a first sealing ring 113 is sandwiched between the connecting housing 111 and the socket housing 112. Specifically, an annular groove is formed on the inner wall of the right end of the connecting housing 111 or the outer wall of the left end of the socket housing 112 as a first sealing groove. The first sealing ring 113 is fitted in the first sealing groove so that the connecting housing 111 and the socket housing 112 that are inserted into each other achieve a sealing fit.

[0065] Corresponding to the embodiment described above that includes a first threaded structure and a positioning through hole 1121, as follows: Figure 2 and Figure 3 As shown, the first threaded structure is set at the left end of the connecting housing 111 to facilitate the connection of the pipe port structure. The positioning through hole 1121 is opened at the right end of the socket housing 112 to facilitate the positioning of the plug inserted from the right side of the seat 11. The wear-resistant sleeve 3 is sleeved inside the socket housing 112. With this arrangement, when assembly is required, first insert the wear-resistant sleeve 3 from left to right into the socket housing 112 and fix it. Then, insert the sealing ring 21 into the socket housing 112, then insert the flow guide 12 into the socket housing 112. Finally, install the connecting housing 111 on the left end of the socket housing 112. The layout of this fluid connector is reasonable and easy to disassemble and assemble.

[0066] Based on the above embodiments, a second sealing ring 8 and a third sealing ring 9 are also included; the inner wall of the socket housing 112 has a second sealing groove, and the second sealing ring 8 is sleeved in the second sealing groove; the outer periphery of the first end of the guide member 12 has a third sealing groove, and the third sealing ring 9 is sleeved in the third sealing groove.

[0067] Specifically, such as Figure 2 As shown, a second sealing groove in the annular shape is provided on the peripheral wall of the socket housing 112 with a small diameter channel in the middle, so as to fit a second sealing ring 8, for sealing and engaging with the seat 11 when the sealing ring 21 moves to the position where the seat 11 has a small diameter channel; and a third sealing groove in the annular shape is provided on the outer periphery of the right end of the flow guide 12, so as to fit a third sealing ring 9, for sealing and engaging with the flow guide 12 when the sealing ring 21 moves to the position where the seat 11 has a small diameter channel.

[0068] Based on the above embodiments, the sealing ring 21 has a first cylindrical section 211 and a second cylindrical section 212, the cross-sectional dimension of the first cylindrical section 211 is larger than the cross-sectional dimension of the second cylindrical section 212; the inner wall of the socket housing 112 has an annular protrusion 1122, the second sealing groove is provided in the annular protrusion 1122, and the second cylindrical section 212 can be inserted into or withdrawn from the inner cavity of the annular protrusion 1122; the first cylindrical section 211 is slidably fitted to the wear-resistant sleeve 3; and the stepped surface of the sealing ring 21 located between the first cylindrical section 211 and the second cylindrical section 212 can abut against or separate from the positioning surface at the end of the annular protrusion 1122.

[0069] Specifically, such as Figure 1 and Figure 2 As shown, the sealing ring 21 has a stepped structure, and the cross-sectional dimension of the first cylindrical section 211 at the left end of the sealing ring 21 is larger than the cross-sectional dimension at its right end, that is, the diameter at the left end of the sealing ring 21 is larger than the diameter at its right end; correspondingly, the inner wall of the middle cylindrical section of the socket housing 112 has annular protrusions 1122. After being inserted into the socket housing 112 from left to right, the small-diameter section at the right end of the sealing ring 21 can be inserted into the annular protrusions 1122 of the socket housing 112, while the left end of the sealing ring 21 is inserted into and slides in the large-diameter channel at the left end of the socket housing 112.

[0070] In use, the sealing ring 21 moves to the right under the push of the first reset member 22. Figure 2 When the position is shown, the stepped surface between the first cylindrical section 211 and the second cylindrical section 212 in the sealing ring 21 abuts against the left end face of the annular protrusion 1122, that is, the left end face of the annular protrusion 1122 is the positioning surface.

[0071] Based on the above embodiments, the connecting housing 111 has a third cylindrical section 1111 and a fourth cylindrical section 1112. The third cylindrical section 1111 has a first threaded structure, and the fourth cylindrical section 1112 has a second threaded structure. The inner diameter of the third cylindrical section 1111 is smaller than the inner diameter of the fourth cylindrical section 1112. The second end of the guide member 12 abuts against the stepped surface between the third cylindrical section 1111 and the fourth cylindrical section 1112.

[0072] Specifically, such as Figure 2 and Figure 3 As shown, the internally threaded structure in the third cylindrical section 1111 at the left end of the connecting housing 111 is the first threaded structure, and the internally threaded structure in the fourth cylindrical section 1112 at the right end of the connecting housing 111 is the second threaded structure. The inner diameter of the third cylindrical section 1111 is smaller than the inner diameter of the fourth cylindrical section 1112, that is, the connecting housing 111 has a stepped through hole inside. The guide 12, which extends into the socket housing 112 at the right end, is supported on the stepped surface in the connecting housing 111 at the left end to achieve the positioning of the guide 12.

[0073] Based on the above embodiments, both the first reset member 22 and the second reset member 4 are springs; one end of the first reset member 22 abuts against the guide member 12 and the other end abuts against the sealing ring 21; one end of the second reset member 4 abuts against the socket housing 112 and the other end abuts against the positioning sleeve 5.

[0074] like Figures 1 to 3 As shown, the first reset member 22 extends laterally, and the left end of the guide member 12 has an edge structure so as to be supported on the stepped surface in the connecting housing 111. The left end of the first reset member 22 abuts against the right end face of the left end edge structure of the guide member 12, and the right end abuts against the sealing ring 21.

[0075] The second reset member 4 also extends laterally, and there is a gap between the positioning sleeve 5 and the right end of the socket housing 112 to accommodate the second reset member 4. The left end of the second reset member 4 abuts against the socket housing 112 and the right end abuts against the positioning sleeve 5, so as to push the positioning sleeve 5 to move to the right.
